Sinichella gen.nov.

Type species: Sinichella chengkou nov.sp.

D e s c r i p t i o n: The new genus differs from the other genera of Xantholinini from the Palaearctic and Oriental regions by the somultaneous presence of the following characters: superior epipleural line of pronotum not joint with the inferior line; maxillary palpi with last segment wide to the base about as the previous segment one and longer than it ( Fig. 85 ); labial palpi with long segments, the last longer and narrower than the previous one ( Fig. 86 ); gular sutures longly contiguous; antisternal plate with suture; mandibles with a wide lateral groove; antennae with 2° article scarcely longer than 3°; frontal grooves evident; ocular grooves superficial with some punctures; labrum bilobed; surface of head without micro-sculpture, with sparse micro-puncturation and deep, dense puncturation; pronotum with dorsal and lateral series; metatibiae with the apical ctenidium only; anterior tarsi a little dilated; male genital segment with characteristic tergite and sternite; aedeagus of particular shape, with long, symmetrical parameres.
