Diagnosis: The main diagnostic characters of Eupachypeltis are: presence of punctures on clavus and R + M (as in fig. 11C, D in Namyatova et al., in press); presence of three tubercles on frons (as in Fig. 10B, M ); head almost flat dorsally in lateral view; antennal fossa tuberculate (as in Fig. 10L ); distance between antennal fossae longer than antennal fossa diameter; ASI swollen medially (as in fig. 9D in Namyatova et al., in press); ASII subequal to head and pronotum combined, filiform; labium slightly surpassing posterior margin of pronotum; LSI–II only twice as long as wide; metepimeron distinctly enlarged, subtriangular, twice as long as wide (as in Fig. 13E ); costal margins straight, corium not broadened posteriorly; membrane cell forming right angle (fig. 13B in Namyatova et al., in press); distance from cell to apex of membrane subequal to half of cell length; outgrowths on phallobase supporting ductus seminis very short; ductus seminis shorter than phallotheca length, without coils ( Fig. 15I ); DLP without sclerotized bands ( Fig. 19A ).
