- Fore wing marginal vein with seta M6 present (Fig. 6) or if seta M6 absent then marginal fringe on fore wing short, fore wing LMS:fore wing width about 0.05); occipital margin narrowly rounded or acute; hind wing shape variable.............. 3
2(1) Head prognathous and subrectangular in frontal aspect; mesotibia subcylindrical and without long spines on dorsal surface; mandibular ducts not enlarged apically; male genitalia with digitus bearing a single apical denticle, and bearing medial denticles on phallobase between digiti.............................................................. Clytina Erd ỏs
- Head hypognathous and approximately round in frontal aspect; mesotibia obconic and with long spines on dorsal surface; mandibular ducts enlarged apically; male genitalia with digitus bearing two denticles, one at apex and one at midpoint, and without medial denticles between digiti.............................................. Thysanus Haliday in Walker
3(1) Protibia calcar without a comb of fine setae; medial sclerite of propodeum without lamelliform process; female antenna with 4 anelli; male with 3 anelli; mesofemur usually with 3 or 4 long spines; body entirely black or dark brown, often with metallic reflections, but without light coloration on mesosoma or metasoma.......................... Chartocerus Motschulsky
- Protibia calcar with a comb of fine setae; medial sclerite of propodeum with lamelliform process; female antenna variable but often with 3 anelli; male antenna also variable but usually with 3 anelli; mesofemur with 1 or 2 long spines; body color variable...........................................................................

4(3) Fore wing submarginal vein with 1 seta; hind wing marginal vein with 2 setae; hind wing with parallel margins and discal seta absent; male genitalia without medial denticles......................................... flavopalliata species group
- Fore wing submarginal vein with 2 setae (one species with 1 seta but lacking other features above); hind wing marginal vein with 1 seta; hind wing with posterior margin narrowly or broadly rounded and with discal seta present or absent; male genitalia with medial denticles variable........................................................................... 5
5(4) Female antenna with 4 anelli; male antenna with 3 anelli; hind wing without discal seta; male genitalia without medial denticles...................................................................... dipterophaga species group (part)
- Antenna of either sex with 1–3 anelli; hind wing with or without discal seta; male genitalia with medial denticles........ 6
