Dendromyia Theobald, 1903

ADULTS ‒ Species of Dendromyia differ from species of other subgenera of Wyeomyia principally in features of the male genitalia, larvae and pupae; members are morphologically distinct from but more similar to species of Caenomyiella than to species of the other subgenera. ADULTS ‒ Clypeus with or without scales; mesopostnotum with patch of numerous setae, no scales; paratergite without scales; lower mesokatepisternal setae extend above dorsal margin of mesomeron; upper calypter of wing with or without marginal setae. MALE GENITALIA ‒ Tergum IX lobes variable, indistinct or noticeably produced, with strongly developed setae; gonocoxite with long lateral seta and tergal triad; gonostylus without stem, with 2 or 3 lobes arising at base (lobe C, lobe M and lobe AE or AE/M), lobes variously developed; aedeagus as broad as long or longer than wide, broadest at mid-length, submedian tergal arms not joined; paraproct with 1 or 2 apical teeth, cercal setae present. LARVAE ‒ Setae 4‒6-C single, 5-C inserted more or less level with or slightly anterior to seta 7-C, seta 6-C inserted anterolateral to seta 5-C on line between setae 4- and 7-C; seta 1-A single, inserted near apex of antenna; maxilla elongate, with strongly developed apical tooth, seta 4-Mx single, stout, shorter than maxillary brush, hypostomal sclerite ill-defined, seemingly fused to maxillary body and maxillary palpus, seta 6-Mx small, single; seta 14-C strongly developed, significantly longer than seta 15-C, inserted posterior to or on level with setae 12,15-C; seta 1-P usually single, inserted posterolateral to and longer than setae 2,3-P; seta 4-P relatively short, multi-branched; seta 11-P,M,T single, short, spine-like; seta 7-M small, branched, similar to seta 4-M; seta 4-T small, with 1‒4 branches; seta 8-T inserted anterior to anterolaterad of sclerite bearing setae 9‒12-T; seta 13-T multi-branched, not much longer than 0.5 length of thorax, inserted near lateral margin posterior to posteromesad of setae 9‒12-T; seta 1-I,II small, usually similar in size to seta 2, seta 1-III‒VI branched, 0.5‒1.0 length of segment; seta 2-I‒VII short, single, seta 2-III‒VII inserted anteromesal to seta 1; seta 9-I‒VI short, single; seta 13-I inserted near anterior margin of segment, 13-II‒VI inserted slightly anterior to seta 7 on or near mid-length of segment; comb plate absent, dorsal comb scales spine-like with short fringe at sides, ventral scales spine-like or squamiform with apical and lateral fringes; siphon with single mid-posterior row of pecten spines beyond level of seta 1-S, seta 1-S inserted some distance from base of siphon, only 1‒4 seta la-S and normally 3 seta 2a-S present; seta 4-X much shorter than setae 1‒3-X, multi-branched. PUPAE ‒ Cephalothorax and abdomen without spots; trumpet gradually slightly broadened distally, narrowly funnel-like; seta 1-I strongly developed, dendritic, with 3 or 4 primary stems and usually numerous apical branches; setae 1,2-II‒VII inserted near posterior margin of tergum, seta 2-I inserted lateral to seta 2, seta 2-II‒VII inserted a greater distance mesal to seta 1; seta 3-II,III,VII inserted lateral to seta 1, seta 3-IV inserted anterior and seta 3-V,VI inserted mesal to seta 1; seta 6-II single, long, reaching well beyond posterior margin of tergum III, seta 6-VII inserted on sternum ventrad of seta 9-VII; paddle longer than tergum VIII, elongate triangular in shape, bluntly pointed apex fringed with short to long spicules that diminish in length and presence on both inner and outer margins.
