Phoniomyia Theobald, 1903

ADULTS ‒ Proboscis unusually long and slender, much longer than forefemur, curved downward; 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 weakly to strongly produced, setae short and stout or longer and narrower and often with apices bent laterad; gonocoxite rather long and relatively slender, tergal triad and basal mesal lobe absent; gonostylus either usually short and setose or divided proximally into 2 long arms, longer ventral arm with an elongate knife-like arm along one side; aedeagus elongate, apical tergal arms not fused to form an apical tergal bridge; proctiger with apical teeth, cercal setae present. LARVAE ‒ Setae 4‒6-C usually multi-branched (may be single or double in Wy. theobaldi), 4-C not inserted close to median labral plate, on level with antennal prominence, 6-C inserted anterior to seta 7-C, 5-C usually inserted more or less on level with seta 7-C (distinctly anterior to 7-C in Wy. palmata); seta 1-A single or branched, inserted about 0.75 from base of antenna; maxilla longer than wide, with very small apical tooth, seta 3-Mx borne in lateral cup-like notch (as in species of Hystatomyia), seta 4-Mx single, stout, brush-tipped, as long as or longer than maxillary brush, seta 6-Mx single, arising from distinct hypostomal sclerite or sclerite unapparent with seta 6-Mx apparently arising from membrane; seta 15-C inserted posterior to seta 12-C at level of mid-length of labiogula; seta 1-P multi-branched, as long as or slightly shorter than seta 2-P; seta 4-P short, multi-branched; seta 11-P,M,T normal, not spine-like; seta 4-T relatively large, about as long as seta 1-M; seta 13-T multi-branched, about 0.5 length of thorax; comb plate absent, comb scales generally numerous, in patch; siphon long and tapered, with single or 2 close-set posterior rows of pecten spines, seta 1-S branched, inserted about 0.25 from base of siphon, setae la,2a-S long and numerous; saddle without spicules on posterior margin; seta 1-X with 1‒3 branches, usually double; seta 4-X multi-branched, very short, <0.25 length of seta 1-X. PUPAE ‒ Cephalothorax and abdomen often with variable pattern of pigmentation; trumpet slender and more or less cylindrical; seta 1-I strongly developed, dendritic; 2-II‒VII inserted near posterior margin of terga, 2-II inserted between setae 1,3-II, seta 2-III‒VII inserted mesal to seta 1; seta 3-II inserted lateral to seta 1, 3-IV‒VI inserted anterolateral to seta 1; seta 6-II single, long, reaching well beyond posterior margin of tergum III, seta 6-VII inserted on tergum posterior to seta 9-VII; paddle length variable, as long as or distinctly longer than tergum VIII, generally ovoid, apex rounded or slightly narrowed, with or without short apical spicules.
