1] in a broad definition of the genus
Macquartia. For practical reasons, and to reduce the amount of changes in traditional binominal usages.
Generic diagnosis. Macquartia may be easily distinguished from other tachinids by the following characters: hairs or setulae on posteroventral half of head all black, without any pale hair. Second costal section with fine hairs ventrally. Scutum with three pairs each of presutural dorsocentral bristles and postsutural intra-alar bristles. Preapical posteroventral seta on hind tibia distinctly shorter than the preapical anteroventral seta.
Description. Body length more than 4.0 mm. Eye densely covered with hairs, each hair longer than combined diameter of three eye facets. Frons of male at most one-fourth eye width in dorsal view, proclinate orbital setae absent in male, or with two proclinate orbital setae in female. Ocellar setae developed, proclinate. Lower margin of face usually not visible in profile. Facial ridge with setae on lower half or less. Hairs or setulae on posteroventral half of head all black, without pale hairs. First flagellomere not pointed apically, less than two times as long as pedicel. Arista thickened on basal one-fourth or less, first aristomere distinctly shorter, arista short pubescent, the longest hairs longer than basal diameter of arista or plumose. Palpus dark brown or at least reddish yellow at apex. Scutellum and abdomen black. Scutum before suture without dark stripes, with two or three pairs of presutural and usually three postsutural dorsocentral setae, two or three postsutural intra-alar setae present. Scutellum usually with three pairs of setae along its margin, with strong crossed apical setae, but weaker than subapical scutellar setae, lateral scutellar setae absent or present. Prosternum and proepisternum bare. Postpronotum with two or three setae, arranged in a straight line. Katepisternum with two or three setae, anepimeral setae well developed, anatergite almost always with a group of minute hairs or setulae below lower calypter. Second costal section of wing with fine hairs ventrally. Only base of vein R4+5 with hairs. Wing cell r4+5 open or with a very short petiole, Bend of vein M without continuation or with a very short stub. Dorsal surface of lower calypter bare, divergent from scutellum or not divergent from scutellum. Legs usually black, sometimes reddish yellow. Inner anterior surface of fore coxa bare or predominantly bare. Preapicall posteroventral seta on hind tibia distinctly shorter than preapical anteroventral seta. Middorsal depression on abdominal syntergite 1 + 2 not or extending back to the hind margin of that segment, without or with two median marginal setae, fourth tergite barely with a complete row of discal setae. Male genitalia very long, middle part of cerci narrowed and pointed, surstyli more or less narrowed.

Relative lengths of costal sectors second, third, and fourth approximately as 1:3.6:1.2; vein M from dm-cu crossvein to its bend about five times the distance between the bend and wing hind margin. Legs yellow, expect tarsi dark brown. Abdomen. Third tergite without median marginal seta; fifth tergite with two discal setae. Base of sternite 5 bluntly round, the depth of V-shaped median cleft of sternite 5 about 1/5 of the sternite length, posterior lobe bluntly rounded apical. Pregonite short and thick, postgonite short and pointed, distiphallus narrowed on apical half, and bluntly round at apex. In caudal view, cerci thick and short, apex bent backward, surstylus thick and apex slightly bent inward. In lateral view, cerci thick and its apex bent backward, surstylus thick and spoon-like, apex bent front-outward.
Female. Differing from male as follows: frons wide, vertex 0.27–0.3 of head width. Parafacial bare. Frontal vitta wider than fronto-orbital plate, latter with sparse black hairs. Seven frontal setae, one outward prevertical seta, two proclinate outer orbital setae, outer vertical seta about 1/2 length of inner vertical seta. Tegula brown at base and reddish at apical half, basicosta reddish yellow. Pulvilli yellowish, claws and pulvilli shorter than fifth tarsomere. Fore tibia with 2–3 anterodorsal setae, lower one longer, 1 preapical anterodorsal and 1 preapical dorsal seta in equal length, and 1 preapical posteroventral seta. Mid femur with 2–3 anterior setae and 2 preapical posterodorsal setae. Mid tibia with one anterodorsal, two posterior, and one anteroventral seta, apex with one anterior, one anterodorsal, one dorsal, one posterodorsal, one anteroventral, and one posteroventral seta. Hind femur with a complete row of anterodorsal setae, one anterior and three ventral (two at basal half, one at apex) setae. Hind tibia with a row of irregular anterodorsal setae, lower two of them strong, two posterodorsal and three anteroventral (lower two longer) setae, one preapical dorsal, one short anterodorsal and one preapical anteroventral seta. Abdomen without discal seta on intermediate tergites, syntergite 1 + 2 with 2–3 lateral marginal setae; third tergite with two median marginal setae or absent, with 2–3 lateral marginal setae; fifth tergite with a complete row of discal setae.
Etymology. The specific epithet is taken from a character of this species, i.e., legs reddish yellow. It is derived from the Latin adjective flavus (=yellow) and the Latin noun femur (=femora).
Distribution. China (Hubei).
Remarks. This new species is similar to
Macquartia flavipedicel sp. nov., but differs from it having reddish yellow basicosta and legs. The major differences of four new species are listed (
