Spilonympha Motta & Lourenço-de-Oliveira, 2005

Species of Spilonympha differ from species of other subgenera of Wyeomyia in features of the male genitalia, larvae and pupae; members are morphologically distinct from but more similar to species of Cruzmyia than to species of the other subgenera. ADULTS ‒ Similar to the adults of other subgenera of Wyeomyia in overall habitus; proboscis shorter than forefemur, thickened distally; mesopostnotal setae present, some scales also present; paratergite without scales; lower mesokatepisternal setae extend above dorsal margin of mesomeron; upper calypter of wing without marginal setae. MALE GENITALIA ‒ Tergum IX lobes small, each with few strong setae; gonocoxite without long setae except for long lateral seta and 2 tergomesal setae (= tergal triad); gonostylus with conspicuous long stem, lobes A, C, E and M present at apex; aedeagus longer than wide, broadest at mid-length, submedian tergal arms joined, apical tergal arms not joined; paraproct with 1 or 2 apical teeth, cercal setae present. LARVAE ‒ Setae 4‒6-C single, widely separated, 6-C inserted anterior to seta 7-C; seta 1-A single, inserted near apex of antenna; maxilla short, with strong apical tooth, seta 4-Mx single or bifid, relatively long, about as long as maxillary brush, seta 6-Mx inserted on margin of maxillary body or on hypostomal sclerite when present; seta 14-C about 3 times as long as seta 15-C; seta 15-C inserted at most slightly posterior to seta 14-C, on level with seta 12-C; seta 1-P inserted posterolateral to setae 2,3-P; seta 4-P relatively short, multi-branched; seta 11-P,M,T single, short, spine-like; seta 7-M relatively weakly developed, branched, about as long as seta 3-M; seta 8-T inserted laterally between seta 7-T and sclerite bearing setae 9‒12-T; seta 13-T multi-branched, shorter than 0.5 length of thorax; seta 1-I,II small, similar in size to seta 2, seta 1-IV‒VII multi-branched, about half length of segment; seta 2-I‒VII short, single, 2-III‒VII inserted far mesad of seta 1, 2-III,IV inserted nearer to seta 1 than to midline of segment, 2-V‒VII inserted approximately midway between seta 1 and midline; seta 13-III,IV inserted posterior to seta 12, slightly posterior to level of seta 7; comb plate present, comb scales spine-like, fringed at sides, borne on posterior margin of sclerite; siphon with distal posterior row of pecten spines, seta 1-S inserted near base of siphon, seta la-S in more or less straight posterolateral row, seta 2a-S more numerous, inserted in more or less double anterolateral row; seta 4-X much shorter than setae 1‒3-X, multi-branched. PUPAE ‒ Cephalothorax and abdomen darkly pigmented or with pattern of dark pigmentation and interspersed pale spots; trumpet nearly cylindrical or expanded near mid-length; seta 1-I strongly developed, dendritic, seta 1-III,V,VI inserted lateral to setae 2 and 3; seta 2-II‒VII inserted near posterior margin of terga, 2-II inserted lateral to seta 1, 2-III‒VII inserted mesal to seta 1; seta 3-III,V,VI inserted mesal to seta 1, 3-IV inserted noticeably anterior to seta 1; seta 5-IV,V strongly developed, long, extending well beyond posterior margin of following tergum; seta 6-II as long as or longer than tergum III, 6-VII inserted on tergum posterior to seta 9-VII; paddle long and broad, outer part much broader than inner part, more than twice as broad, inner and outer margins serrate.
