Simple Summary
This study explores the aphid genus Drepanaphis, focusing on its diverse species and their relationships with host plants across North America. The research includes a comprehensive taxonomic revision, identifying 18 species with the addition of Drepanaphis robinsoni sp. nov. Detailed descriptions and illustrations cover 44 morphs, including alate viviparous females, oviparous females and males, accompanied by new identification keys. For the first time, sexual morphs of 15 species, particularly oviparous females, are documented. Current range maps for all species and microscopy images of key morphological features contribute to a more comprehensive understanding of this genus, which has received limited study in the past.
Abstract
The Nearctic aphid genus Drepanaphis Del Guercio, 1909, the largest within the subfamily Drepanosiphinae (Hemiptera: Aphididae), is characterised by distinctive dorsal abdominal tubercles. This study presents a comprehensive taxonomic revision of the genus, expanding the recognised species to 18, including the newly described Drepanaphis robinsoni Malik sp. nov. Detailed descriptions and figures for 44 morphs, encompassing alate viviparous females, oviparous females and males, are provided, with new identification keys for all known species and morphs. The sexual morphs of 15 species, particularly oviparous females, are documented for the first time. Morphometric and principal component analyses (PCA) are employed to distinguish the studied taxa. This study identifies and corrects numerous misidentifications in museum collections, previously labelled as D. acerifoliae, D. choanotricha, D. kanzensis, D. knowltoni, D. parva, D. sabrinae or D. tissoti. Furthermore, it revalidates the distinct status of D. nigricans and D. tissoti, which had been synonymised in earlier works. Current range maps for all species and images of key morphological features obtained through light and scanning electron microscopy are also presented, providing a more complete understanding of this understudied genus.
