Ocypus (Pseudocypus) teuthras sp. nov.

(Figs. 171–175)

Type material. Holotype (male): CHINA: Sichuan: “CHINA Sichuan Jingping Shan W of MoFangGou 3345 m 28.12.983'N 101.44.285'E 28.5.– 4.6.2005 R. Sehnal & M. Tryzna ” ( ASC).

Paratypes: CHINA: Sichuan: same data as holotype, 2 ♂♂ ( ASC) .

Diagnosis. A medium-sized species, sharing most character states with O. semenowi , but differing from it by differently shaped aedoeagus, and by some external characters, as given in the description.

Description. Average size slightly larger, body shape more robust. Abdomen entirely black, i.e. not becoming paler at apex. Pubescence of dorsal side of entire body deep black; antennae piceous with first three segments rufobrunneous. Head larger, more distinctly wider than long (ratio 1.35) eyes relatively smaller, tempora more distinctly longer than eyes from above (ratio 2.66); punctation of head similar, but finer and less dense, microsculpture on interspaces between punctures similar, but slightly finer. Antenna more robust and longer, segment 3 longer than segment 2 (ratio 1.40), segments 4–7 longer than wide, gradually becoming shorter, outer segment about as long as wide. Pronotum slightly longer than wide (ratio 1.15); punctation of pronotum finer. Punctation of elytra finer, difficult to observe among dense, granulose microsculpture. Punctation of abdominal tergites finer, microsculpture becoming gradually coarser toward lateral margins of each tergite.

Male. Sternite 8 with rather deep, moderately wide, obtusely triangular medioapical emargination. Genital segment with sternite 9 with narrow, moderately long basal portion, distinctly emarginate apically (Fig. 171). Tergite 10 with slightly differentiated apical portion with narrowly arcuate apex, bearing numerous long setae at and near apical margin (Fig. 172). Aedoeagus moderately large, shaped as in Figs. 173–175; median lobe elongate, narrow, apical portion slightly asymmetrical, with arcuate to subtruncate apex, with bisinuate formation on face adjacent to paramere just below apex (Fig. 174); paramere large, situated on median lobe slightly asymmetrically, on face away from median lobe with distinct, characteristically curved carina; apical portion of paramere slightly asymmetrical, with obtusely rounded apex not quite reaching apex of median lobe; underside of paramere with numerous sensory peg setae, forming two lateral groups connected along apical margin of paramere; apical setae minute, situated as in Fig. 175.

Female. Unknown.

Length 13.0–15.0 mm.

Bionomics. Nothing is known about the habitat requirements of this species.

Geographical distribution. Ocypus teuthras is at present known only from the type locality in north-central Sichuan .

Recognition and comments. Ocypus teuthras may be easily distinguished from O. semenowi , in addition to the entirely differently shaped aedoeagus (see Figs. 161, 173), by the characters given in the diagnosis. It is also similar to O. glabrio , for the distinguishing characters see under the latter species.

One of the paratypes is missing all but 3 basal segments of the left antenna, and all but 4 basal segments of the right antenna.

Etymology. The specific epithet is the name of Teuthras, - antis, m, a king of Mysia , father of Thespius, in apposition.
