3.1. Taxonomic Documentation of Acalyptris Meyrick Species from the Tropical Dry Forests of the Pacific Coast of Honduras
Among the materials obtained by us in the dry season from the tropical dry forests of Honduras, minuscule, grey-colored moths were found to be abundant and distinctly predominated (
Figure 3). Laboratory dissections of the genitalia structures showed that all examined species possess the complex of morphological characters characteristic of the genus
Acalyptris Meyrick [
39], including the unique lateral apodemes. The wing venation of the examined species was neither studied nor deemed necessary, as the genitalia structures clearly exhibited the differences. Additionally, wing venation provides minimal diagnostic value due to its highly reduced state and resulting uniformity.
Our morphological studies led to the identification of five species. Two species,
Acalyptris lascuevella Puplesis & Robinson and
A. basicornis Remeikis & Stonis, were new to the Honduran fauna but previously known from neighboring countries:
A. lascuevella from Belize [
12] and Mexico [
9,
15], and
A. basicornis from Guatemala [
9,
13]. Based on the specimens sampled in Honduras and subsequently examined during the preparation of this paper, we also described three new species:
Acalyptris podenasi sp. n.,
A. palpiformis sp. n., and
A. tortoris sp. n. Along with our morphological examination, we have barcoded all new species, as well as
A. lascuevella, which was exceptionally abundant in the available materials and exhibited some morphological variation.
Acalyptris podenasi Stonis, Dobrynina & Remeikis, sp. nov.
(accessed on 24 August 2024)
Diagnosis. The exact taxonomic position of this new species within the
Acalyptris species groups is currently not fully understood (see Discussion). Tentatively, it is placed in the
A. murex species group as a satellite species. Externally,
A. podenasi sp. nov. (
Figure 3a–c and
Figure 4) closely resembles the very similar
A. lascuevella Puplesis & Robinson, 2000 (see
Figure 3i,j), making them easily confused based solely on external characters. In male genitalia,
A. podenasi sp. nov. can be distinguished from all other
Acalyptris species, including
A. lascuevella, by the combination of a short but wide genital capsule, a slender transtilla with small sublateral processes, a broadly rounded pseuduncus caudally, an anchor-shaped juxta, and a phallus with one distally pointed carina and one rounded or truncate apical lobe. Notably, the anchor-shaped juxta alone can provide the immediate identification of
A. podenasi sp. nov. Among the female genitalia features,
A. podenasi sp. nov. is characterized by an irregular vaginal sclerite, a pair of pointed vaginal lobes, and unique signa with unusually large cells.
Barcodes. We barcoded four male paratype specimens from the Pacific coast of Honduras, 11–16 February 2023 and 18–19 March 2023 (with genitalia slides DV158, DV162, DV183, and RA1148); sequences are available in GenBank (the accession IDs: PQ008650–PQ008653) and BOLD (the process IDs: ACAL001-24–ACAL004-24).
Male (
Figure 4). The forewing length ranges from 1.3 to 1.5 mm, with a wingspan of 3.0 to 3.3 mm (n = 28).
The head: The palpi are silvery cream; the frontal tuft varies from brownish-orange to pale orange; the collar consists of two somewhat indistinct tufts of piliform scales; the scape is unusually large, cream-colored with sparse scattered scales; the antenna is shorter than one-third of the length of the forewing; the flagellum is blackish-grey to pale grey, silvery-cream on the underside.
The thorax: The tegula is silvery-cream, speckled with dark scales; the thorax is predominantly silvery-cream with a few dark scales. The forewing is densely irrorated with black-brown scales; it bears two large, irregular, almost merging silvery-cream or silvery-white (occasionally cream) postmedian costal and dorsal spots, or a silvery-cream to silvery-white oblique postmedian fascia; sometimes the dark scales of the forewing are less developed in the basal half, giving it a silvery-cream appearance; the fringe is cream to silvery-cream or silvery-white, pale grey on the tornus, with a distinctive fringe line; the underside of the forewing is blackish-grey. The hindwing and its fringe are greyish-cream to cream; the apical third is covered with tiny pale grey scales (androconia), visible at certain angles. The legs are glossy cream, covered with glossy grey scales on the upper side.
The genitalia (
Figure 5): The capsule measures 180–190 µm in length and 140–175 µm in width. The pseuduncus is widely rounded. The uncus is inverted Y-shaped, with a short, ventrally directed process. The gnathos possesses a stout caudal process, a slender median plate, and well-developed lateral arms. The lateral apodeme is relatively short and slender, with an enlarged, lobe-like caudal part. The valva is 105–110 µm long, almost triangular, heavily papillated medially, with a subbasal bulge. The transtilla features a slender transverse bar and tiny, pointed sublateral processes. The vinculum is relatively wide but short, with two short, triangular lateral lobes. The phallus is 175–190 µm long and 60–75 µm wide, with a rounded or truncated apical lobe and an irregularly shaped, distally thickened carina; cornuti are absent. The juxta is distinctive and thickened, anchor-shaped (note: the shape may distort during inaccurate dissections).
Female. Externally, the female is similar to the male. Genitalia (
Figure 6 and
Figure 7): The total length of the genitalia is approximately 440 µm. The abdominal apex is wide and slightly rounded caudally, with two rows of short setae. Both the anterior and posterior apophyses are slender, with the posterior ones distinctly longer. The vestibulum contains an irregular vaginal sclerite. The corpus bursae is oval-shaped, densely covered with minute pectinations; the signa have exceptionally large cells, up to 35–40 µm in width. The ductus spermathecae is with compressed, heavily thickened, irregular coils and a lobe-shaped, rounded vesicle.
Bionomics. The host plant remains unknown. Adults are attracted to light. All currently available specimens were abundantly collected at a light trap from early February to the end of March, during the peak of the dry season. Otherwise, the biology of this species is unknown.
Distribution. This new species occurs and appears to be very common in the tropical dry forests along the Pacific coast of Honduras, including the islands of the Gulf of Fonseca.
Etymology. The species is named after our colleague Prof. Dr. Sigitas Podėnas, an entomologist specializing in Tipulimorpha, the Director of the State Research Institute Nature Research Centre (NRC), and an Academician of the Lithuanian Academy of Sciences, in recognition of his passion for studying insect diversity. We also greatly appreciate his efforts in providing the wonderful image of the nepticulid moth included in this paper (see
Figure 4).

Remarks. Identifying species from the tropical dry forests of Honduras based solely on external characteristics can be challenging or even impossible. A sizeable additional collection was excluded from the type series and deposited at the BRG/NRC. The material, left undissected, comprises male and female specimens of two externally similar species, Acalyptris podenasi sp. nov. and A. lascuevella Puplesis & Robinson.
Acalyptris palpiformis Stonis, Remeikis & Diškus, sp. nov.
(accessed on 24 August 2024)
Diagnosis. Acalyptris palpiformis sp. nov. is assigned to the A. trifidus species group (see Molecular Considerations). Externally, this new species is characterized by two pale postmedian spots and a pale antemedian fascia, setting it slightly apart from other grey-speckled Acalyptris species. In the male genitalia, A. palpiformis sp. nov. can be distinguished from all other Acalyptris species, including those of the A. trifidus group, by the presence of two palpi-like lateral processes of the uncus, as well as a slender valva, transtilla with long pointed sublateral processes, and unique long carinae of the phallus. In the female genitalia, A. palpiformis sp. nov. is characterized by unusually long posterior apophyses, large specific vaginal lobes, and laterally thickened vaginal sclerite.
Barcode. We barcoded one male paratype specimen from Terra Mar, Isla Zacate Grande, Honduras, 20 March 2023 (with genitalia slide no. RA1151); the sequence is available in GenBank (the accession ID: PQ008656) and BOLD (the process ID: ACAL007-24).
Male (
Figure 3e). The forewing length ranges from 1.5 to 1.8 mm; wingspan from 3.5 to 4.0 mm (n = 8).
Head: Palpi cream; frontal tuft pale beige-orange; collar comprised of two tufts of ochre-cream piliform scales; scape yellowish-cream; antenna longer than one third the length of the forewing; upper side of flagellum dark grey with purple iridescence, pale yellowish-grey underside.
Thorax: Tegula cream, speckled with dark brown-grey scales; thorax yellowish-silvery cream, with a few brownish-grey scales. The forewing is densely irrorated with dark blackish-brown scales, with two large cream or yellowish-cream postmedian costal and dorsal spots, and cream or yellowish-cream postmedian fascia, twice wider at the dorsal margin than on the costal margin; the fringe is yellowish-cream, grey-cream to grey on the tornus; the fringe line is indistinctive or absent; the forewing underside is densely irrorated with grey-black or blackish-brown scales. The hindwing is pale grey with pale grey fringe. Legs are cream, covered with grey scales on the upper side.
Abdomen: The upper side is glossy grey-black to black, and the underside is ochre-cream; the genital plates are ochre-cream; the anal tuft inconspicuous, cream.
Genitalia (
Figure 8 and
Figure 9): The capsule is 310–320 µm long, 170–175 µm wide. The pseuduncus is triangular, widely rounded distally. The uncus is complex, consisting of a main body with palp-like lateral processes and a median lobe attached to the main body by lateral arms. The gnathos possesses a stout caudal process, small angular median plate, and well-developed lateral arms. The lateral apodeme is long, rod-like. The valva is 195–210 µm long, slender and slightly sinuous. The transtilla has relatively long, pointed sublateral processes and a transverse bar. The vinculum is relatively short, with two large triangular lateral lobes. The phallus is 290–325 µm long, with two large horn-like pointed carinae: one smaller and curved, another very long and slightly sinuous, almost straight; cornuti absent. The juxta is attached to the phallus, with a curved hook-like distal part and proximal plate.
Female (
Figure 3f)
. Externally, similar to the male. The forewing length is 1.5–1.8 mm; the wingspan is 3.5–4.0 mm (n = 4). The antenna is significantly shorter than one third the length of the forewing.
Genitalia (
Figure 10): The total length of the genitalia is ca. 470 µm. The abdominal apex is triangular, caudally rounded or almost truncated. Both the anterior and posterior apophyses are slender, but the posterior ones are distinctly longer. The vestibulum is with an irregular, laterally chitinized vaginal sclerite and large vaginal lobes. The corpus bursae is oval-shaped, without or with little pectinations; the signa is with large cells. The ductus spermathecae is 3–4 heavily thickened coils and lobe-shaped.
Bionomics. The host plant is unknown. Adults are attracted to light. All currently available specimens were collected at a light trap from February to March, during the peak of the dry season. Otherwise, the biology of this species remains unknown.
Distribution. Currently, this new species is known only from tropical dry forests along the Pacific coast of Honduras, including the islands of the Gulf of Fonseca.
Etymology. The species name is derived from the Latin word “palpus” (meaning a palp), referring to the male genitalia characterized by the unique uncus with two palp-like processes.

Acalyptris tortoris Stonis, Diškus & Dobrynina, sp. nov.
(accessed on 24 August 2024)
Diagnosis. Acalyptris tortoris sp. nov. is assigned to the
A. fortis species group (see Discussion). Externally, this new species is distinguished by an irregular and indistinct oblique cream median fascia and a cream or beige-cream dorsal margin to the forewing, traits that resemble those of
Acalyptris lascuevella Puplesis & Robinson. In the male genitalia,
A. tortoris sp. nov. is easily distinguished from all other
Acalyptris species, including those of the
A. fortis group, by the valva with unique processes (
Figure 11a,b). In the female genitalia,
A. tortoris sp. nov. is characterized by a unique comb-like vaginal sclerite and a rounded ventral plate of the ovipositor.
Barcode. We barcoded one male paratype specimen from Playa Caracol, Honduras, 18.ii.2023 (with genitalia slide DV153); the sequence is available in GenBank (the accession ID: PQ008657) and BOLD (the process ID: ACAL008-24).
Male (
Figure 3g). The forewing length is 1.3–1.5 mm; the wingspan is 3.0–3.5 mm (n = 3).
Head: The palpi cream; the frontal tuft is pale beige-orange; the collar is comprised of two tufts of ochre-cream piliform scales; the scape is cream; the antenna is significantly shorter than one third the length of the forewing; the flagellum is grey on the upper side, but cream on the underside.
Thorax: The tegula is cream, speckled with dark brown-grey scales; the thorax is yellowish-cream with a few brownish-grey scales. The forewing is densely irrorated with dark, blackish-brown scales and of an irregular and indistinctive, oblique, cream median fascia; the latter can be undeveloped; the dorsal margin of the forewing is cream to yellowish cream; the fringe is cream to pale grey on the tornus; the fringe line is distinctive; the forewing underside is densely irrorated with dark brown-grey or blackish-grey scales. The hindwing and its fringe are pale grey. The legs are beige-cream, often covered with black scales on the upper side.
Genitalia (
Figure 11 and
Figure 12): The genitalia capsule is ca. 280 µm long, 170–175 µm wide. The pseuduncus is narrowed and truncated distally. The uncus is inverted Y-shaped. The gnathos possesses a relatively long and slender process, small anteriorly rounded median plate, and well-developed lateral arms. The lateral apodeme is long and slender, rod-like, caudally wide. The valva is 175–180 µm long, with a long slender, distally pointed basal process; the left valva possesses a median spine (a short spine-like process), while the right valva has no spine-like process (a case of genital asymmetry). The transtilla is with slender, relatively long sublateral processes. The vinculum is with two short but wide lateral lobes and relatively shallow anterior excavation. The phallus is 275–280 µm long, with two large, horn-like, sinuous carinae and about five shorter, spine-like carinae. The juxta is absent.
Female (
Figure 3h)
. Externally similar to the male.
Genitalia (
Figure 13): The total length of the genitalia is 620 µm. The abdominal apex is widely rounded, with a rounded thickened plate in the middle ventrally. The anterior and posterior apophyses are almost equal in their length. The vestibulum is a complex, laterally chitinized vaginal sclerite; the median part of the latter is comb-like. The corpus bursae is oval-shaped, with pectinations; each signum with one row of small cells. The ductus spermathecae is 2–3 coils and a lobe-like vesicle.
Bionomics. The host plant is unknown. Adults are attracted to light. All currently available specimens were collected at a light trap from February to March, during the peak of the dry season. Otherwise, the biology of this species remains unknown.
Distribution. Currently, this new species is only known from tropical dry forests along the Pacific coast of Honduras, including the islands of the Gulf of Fonseca.
Etymology. The species name is derived from the Latin word “tortoris” (meaning torture), referring to the heavily armed genitalia with large spines in the male and the comb-like vaginal sclerite in the female genitalia.
Material examined. Holotype: ♂, HONDURAS, The Pacific, Isla Zacate Grande, El Moray (Restaurante Terra Mar), 20 m, 13°21′28.5′′ N, 87°36′06.5′′ W, 15–16 February 2023, leg. J.R.

Acalyptris lascuevella Puplesis & Robinson
Acalyptris lascuevella Puplesis & Robinson, 2000 [
12] (pp. 49,50).
General data. Host plants are unknown. The forewing length ranges from 1.5 to 1.7 mm, with a wingspan of 3.4 to 3.7 mm (n = 12♂♀) (
Figure 3i,j). Originally described from the tropical moist forests of Belize [
12], it was later discovered in a tropical dry forest habitat in Mexico [
15]. Based on our study of large material, we report
A. lascuevella for the first time in Honduras, marking a new distribution record and documenting the genitalia morphology (
Figure 14 and
Figure 15). The females of
A. lascuevella were previously unknown; therefore, they are documented here for the first time (
Figure 15).
Barcodes. We barcoded two male specimens from the Pacific coast of Honduras, 18 February 2023 (with genitalia slide DV170) and 14 March 2023 (with genitalia slide RA1149); the sequences are available in GenBank (the accession IDs: PQ008654, PQ008655) and BOLD (the process IDs: ACAL005-24, ACAL006-24).
Remarks. Our examination of A. lascuevella collected in the tropical dry forests of Honduras revealed variations in the morphology of the male genitalia. The basal inner lobe of the valva varied in shape and the presence of a spine; the juxta also showed slight variations among the examined specimens: in some cases, it appeared less chitinized and slender, while in others, it was strongly chitinized and distinctly triangular. It is worth noting that approximately 70–80% of the studied male genitalia of A. lascuevella exhibited various transitional forms. Additionally, numerous instances were observed where the right valval lobe differed in shape from the left lobe of the same specimen. Moreover, these differences did not correlate with each other or with the variations found in the molecular sequences.
For illustrations of specimens from Belize (the type locality), we recommend consulting the following publication by Puplesis and Robinson (2000) [
12] (Figures 180 and 181).

Acalyptris basicornis Remeikis & Stonis
Acalyptris basicornis Remeikis & Stonis, 2013 [
13] (p. 102).
General data. The host plant is unknown. The forewing length is 1.7 mm; the wingspan is 3.7 mm (n = 1 ♂) (
Figure 3d). The species was originally described from a single specimen collected at a light trap in a moist tropical forest in Guatemala [
13]. Based on the dissection and examination of a single specimen collected in the tropical dry forest (
Figure 16a–e), we now report
A. basicornis from Honduras for the first time, establishing a new distribution record.
Remarks. Our examination of
A. basicornis collected in the tropical dry forests of Honduras did not indicated significant differences in the morphology of the male genitalia (
Figure 16). However, the sublateral processes of the transtilla and the lateral lobes of the vinculum were found to be slightly longer than those of the holotype of
A. basicornis from Guatemala. No barcodes were obtained for this species either previously or during the current research.
Material examined. 1 ♂, HONDURAS, the Pacific, Isla del Tigre, Amapala, Playa Grande, approx. 40 m, 13°16′32.3′′ N 87°39′37.5′′ W, 13–14 March 2023, leg. J.R. Stonis, genitalia slide no. RA1163♂ (MfN).
