ABSTRACT
Two new species of Afidentula, Afidentuladentata sp. n. and Afidentulajinpingensis sp. n. are described from China. Afissasiamensis Dieke is moved to Afidentula comb. n.. All three species are described and illustrated, and a distribution map is given. A key to Asian species of Afidentula is updated. Diagnostic similarities and differences between Afidentula and Afidenta are discussed and illustrated.

Mentions: Species of Afidentula are most similar to Afidenta by the general body shape and colouration (Figs 1a–d, 2a–c, 3a–d, 4a–c), bifid tarsal claws with a large basal tooth (Figs 1k, 2k), abdominal sternite VIII in female not divided longitudinally and female genitalia with oval coxites lacking styli (Figs 1h, o, 2d, o, 3e, j, 4d). Afidentula in the present sense (Szawaryn et al. 2015) constitutes morphological pretty diverse group, especially after inclusion of some species of former Epilachna and Henosepilachna from Madagascar. The Asian species of Afidentula, however, can be easily distinguished from Afidenta (and other Epilachnini genera) by the following combination of characters: mandibular incisor edge smooth (incisor edge microdenticulate in Afidenta, Fig. 1e), ventral surface of incisor edge without tubercles, terminal labial palpomere narrower and shorter than penultimate one (narrower but as long as penultimate one in Afidenta), metaventral postcoxal lines joined on metaventral process in form of straight line (forming somewhat w-shaped line along discrimen in Afidenta), tibial spurs absent (present in Afidenta, Figs 1i-j), abdominal postcoxal lines complete or almost so (distinctly incomplete in Afidenta, Fig. 1h), tegminal strut triangularly expanded apically (simple in Afidenta, Fig. 1m–n), parameres shorter than penis guide and very narrow (in Afidenta, parameres as long as penis guide and much broader than in Afidentula, Fig. 1m–n).
