Agetocera yuae , new species

Agetocera taiwana Chûjô, 1962: 59 (part).

Male. Length 9.5–10.3 mm, width 4.3–5.0 mm. Antennomeres (Figs 5, 13) VIII–XI black, antennomere II shortest, antennomeres III and IV subequal in length and longer than II, antennomeres V–VII subequal in length, longer than II and slightly shorter than III and IV, apically widened, antennomere VIII strongly swollen, with a short sharp process at anterior-lateral angle, antennomere IX (Fig. 17) moderately flattened dorsally, dorsal surface oblique, and more or less concave, dense hairs along outer margin, antennomere X subequal to IX, antennomere XI longest, about 1.6 times as long as X. Genitalia ( Fig. 32 View FIGURES 32 ) with median process extremely flattened laterally; lateral processes short and narrow; endophallus with lateral spiculae long and recurved apically.

Female. Antenna (Fig. 14) filiform, antennomeres VIII–XI black, antennomere VIII conspicuously wider than IX–XI, relative length of antennomeres II–XI about 1.0: 1.5: 1.8: 1.7: 1.7: 1.8: 2.6: 2.3: 2.7: 4.8.

Diagnosis. This species is similar to A. choui with the laterally flattened median process of the male genitalia, but differs by its short and narrow processes, and the long and recurved lateral spiculae of endophallus.
