Elpeytonius Reinert, Harbach & Kitching, 2009

Characters that define the Elpeytonius clade in the phylogenetic analysis of Reinert et al. (2009) are indicated with an asterisk (*). ADULTS – Decumbent scales of vertex all narrow, numerous erect forked scales on occiput and vertex; eyes above antennal pedicels contiguous or separated by diameter of 2 corneal facets; antennal pedicel with few setae and sometimes few scales on mesal surface; maxillary palpus of females dark-scaled, maxillary palpus of males with 5 palpomeres, palpomeres 4 and 5 somewhat downturned, palpomeres 4 and 5 and distal part of 3 with ventrolateral setae; *proboscis pale-scaled ventrally near mid-length; scutum with narrow falcate scales; acrostichal (anterior and posterior) and dorsocentral (anterior and posterior) setae present; scutellum with broad silvery scales on all lobes; paratergite broad, with pale scales; antepronotum with broad silvery scales; postspiracular area without scales; *upper proepisternum with 1−4 setae; lower mesepimeral setae absent; wing dark-scaled with pale scales at base of costa; hindfemur and hindtibia with apical pale scales; hindtarsomeres *1, *2, 3 and 4 with wide apical white band, hindtarsomere 5 entirely or nearly entirely white-scaled; fore- and midungues of females equal, each with tooth, fore- and midungues of males unequal, both foreungues with tooth, larger midunguis with tooth; laterotergite of tergum I with board pale scales, terga I−VI dark-scaled dorsally (*tergum III without median basal pale-scaled area), *segment VII of females laterally compressed. FEMALE GENITALIA – *Tergum VIII with setae on distal 0.60 or less; sternum VIII wider than long, *apex with median emargination, scales absent or few in number, seta 2-S inserted posterior to seta 1-S; 1 large spermathecal capsule (shared with subgenus Catageiomyia); insula is tongue-like with 4−6 distal tuberculi; cercus moderately long, moderately wide, apex broadly rounded, without scales. MALE GENITALIA – Gonocoxite with broad scales, gonostylus attached at apex; *distal part of gonostylus slightly broader than proximal part, with elongate lobe on lateral surface (shared with subgenus Catageiomyia), apex with broad leaf-like gonostylar claw; claspette a short narrow plaque at base of gonocoxite, with few basal setae; aedeagus comprised of 2 sclerites. LARVAE – Seta 4-C with 3−9 branches, inserted mesal to seta 6-C; seta 6-C branched (shared with subgenus Catageiomyia), inserted close to 5-C; setae 1−3-P not inserted on common setal support plate; seta 7-I long, double; seta 12-I absent; seta 5-II longer than seta 3-II (shared with subgenus Catageiomyia); *seta 1-VII ≥ 0.94 length of segment X; comb scales in patch; siphon acus present; spines of pecten evenly spaced; seta 1-S with 2−5 branches, inserted distal to pecten; saddle incomplete, acus absent; seta 1-X single to triple, inserted on saddle; ventral brush (seta 4-X) with branched fan-like setae on grid with both transverse and lateral bars, several precratal setae. PUPAE – Seta 1-CT triple, shorter than seta 3-CT; seta 11-CT single; seta 3-I very long, stout, single; seta 6-I longer than 7-I; seta 3-II inserted mesal or anterior to seta 2-II; seta 5-V longer than tergum VI; seta 9-VII branched, inserted anterolateral to seta 6-VII; paddle without hair-like marginal spicules, apical margin rounded, midrib complete; seta 1-Pa short, double or triple.
