ADULTS ‒ Not currently definitely distinguishable from other subgenera of Wyeomyia, but bearing the following possible differential characters: interocular space broad, scutum with metallic purple, gold, bronze and blue scaling, mesepimeron without scales, abdominal sterna largely or completely without dark scales; proboscis shorter than forefemur, gradually swollen distally; mesopostnotal setae present; paratergite without scales; lower mesokatepisternal setae not extending above dorsal margin of mesomeron; upper calypter of wing without marginal setae. MALE GENITALIA ‒ Tergum IX lobes produced; gonocoxite short, with numerous long setae; gonocoxite short, broad, with numerous long strong setae; gonostylus with short stem, lobe C apparently not developed; aedeagus large, broad, complex, with apical pair of fine divergent ‘horns’; proctiger normal, cercal setae absent.  LARVAE ‒ Head elongate; setae 5,6-C usually single or double, 6-C inserted anterior to seta 7-C; seta 1-A branched, inserted near apex of antenna; maxilla longer than broad, with strong apical tooth, seta 4-Mx single, as long as or longer than maxillary brush, hypostomal sclerite present, bearing single or branched seta 6-Mx; seta 14-C very strongly developed, stellate, inserted slightly if at all anterior to seta 12-C; seta 15-C stellate but much smaller than seta 14-C, inserted far caudad on labiogula; setae 0-P, 1,8,11-P,M,T, 3-P, 14-P,M, 5-M, 4-T and 13-T strongly stellate with numerous branches, seta 13-T about as long as thorax; seta 7-M weakly developed, single or branched; seta 8-T inserted anterior to setae 9‒12-T; setae 1,2,5,9,13-I‒VII, 11-I and 1-VIII strongly stellate with numerous branches; seta 13-I inserted far anterior to seta 7, 13-II‒VI inserted slightly anterior to seta 7; comb plate absent, comb a single long row of close-set spine-like scales; siphon without pecten, seta 1-S single or double, inserted near base of siphon, more or less in line with straight row of single seta la-S, seta 2a-S also a straight row of single setae; saddle nearly complete, narrowly incomplete ventrally; seta 4-X stellate, much shorter than setae 1‒3-X. PUPAE ‒ Cephalothorax and abdomen without spots; trumpet slightly flattened, not laterally expanded; seta 13-CT often present; seta 1-I weakly developed, with 1‒6 branches; seta 2-II‒VII inserted near mid-length of tergum lateral to insertion of seta 1; seta 6-II single, about as long as seta 7, seta 6-VII inserted on sternum ventrad of seta 9-VII; paddle short, length <1.5 greatest width, extending slightly beyond apex of genital lobe, apex fringed with minute spicules.
