Supplementary description.
Male
(
Fig. 2
). Head, pronotum, and antennomeres I and II brownish red; antennomeres III to XI, elytra, and legs brownish black.
Antennae (
Fig. 16
) longer than total length of head and pronotum combined; antennomere I swollen and bent; II compact; III to X pectinate, with branches arising at base of antennomeres; XI fusiform.
Pronotum smooth at apex; postcoxal projections (
Fig. 35
) long; prosternal process not extending contact point of postcoxal projections. Elytra with rows of large, deep, asetigerous punctures in basal half; apical margins finely indented. Mesoventrite with sparse setigerous punctures except for central portion. Metaventrite with evenly arranged fine setigerous punctures except for central portion; metaventral anterior process elongate, as wide as mesoventral posterior process. Metendosternite (
Fig. 52
) without furcal laminae; process extending anteriorly, tapered; furcal arms almost straight, extending anterolaterally.
Protibiae (
Fig. 28
) gently widening from basal 1/3 to apex, weakly curved; meso- and metatibiae almost straight. Tibial spur formula 0–0–0.
Apical margin of abdominal ventrite V broadly and weakly emarginate. Apical margin of pygidium (
Fig. 53
) straight; struts short. Apical margin of ventrite VI (
Fig. 54
) slightly emarginated. Spicular fork (
Fig. 55
) with intraspicular plate, which is 1/2 as long as spicular fork.
CM (
Figs 56–58
) covered with large spines and fine spines, 1/4 as long as tegmen. Tegmen shorter than phallus; phallobasic apodeme fused with phallobasic struts. Phallus widest at 1/3, thence tapered apically.
Female.
Unknown.
