Lacvietina nabanhensis Chang, Li & Yin View in CoL , sp. nov.

( Fig. 1 View FIGURE 1 )

Type material. HOLOTYPE: CHINA: ♂: ‘ China : Yunnan Prov., Nabanhe Conv. (ṂDzāŊǾae ữ), B engganghani (ṞNJḐẽ), 14.i.2004, Li & Tang leg.’ ( SNUC).

Diagnostic description. Male. Habitus as in Fig. 1A View FIGURE 1 (both antennae broken and missing); TBL 3.55 mm, FBL 2.23 mm; head, pronotal disc, elytra, abdomen, and most parts of legs dark reddish-brown, lateral and basal margins of pronotum, posterior areas of tergites, and tarsi yellowish-brown. Head sub-triangular, HL 0.32 mm, HW 0.70 mm, with distinct punctures, without microsculpture; eyes prominent, EyL 0.17 mm; antenna broken. Pronotum strongly transverse, PL 0.70 mm, PW 1.35 mm, PL / PW = 0.52, with punctures similar to those of head, without microsculpture. Elytra transverse, EL 1.00 mm, EW 1.32 mm, EL/EW = 0.75, with punctures similar to those of pronotum, without microsculpture, with slightly produced posterolateral angles. Abdominal surface with fine pubescence, without microsculpture; tergite VIII ( Fig. 1B View FIGURE 1 ) with four short lobes; inner lobes longer than outer ones; sternite VI with shallow, glabrous sub-triangular depression ( Fig. 1C View FIGURE 1 ; arrow) at middle of posterior marginal area; sternite VII ( Fig. 1D View FIGURE 1 ) with posterior margin sub-triangularly emarginate, with granules along posterior margin of sternite; sternite VIII ( Fig. 1E View FIGURE 1 ) with four lobes, deeply incised between inner lobes, mid-length 0.53 times as long as depth of incision. Length of aedeagus ( Fig. 1 View FIGURE 1 F–G) 0.72 mm, parameres elongate and asymmetric, right paramere longer than left one in ventral view, median lobe broad at base and narrowing toward apex.

Female. Unknown.

Comparative notes. Lacvietina nabanhensis is similar to L. lii and L. punctatissima in general appearance. It may be separated from L. lii by the much less distinct impressions on tergites V–VI, and a deeper emargination of sternite VII of the male, and the less curved left paramere of the aedeagus; and from L. punctatissima by the markedly deeper emarginations of male sternites VII and VIII.

Distribution. China: Yunnan.

Etymology. The new specific epithet refers to the type locality of the new species, i.e., Nabanhe Nature Reserve.
