Type material

(1 ♂). Holotype: ♂, labeled 'CHINA: Yunnan / Pass SW from Baoshan / Gaoligong Shan / 4-8.VI.2006, Jeniš lgt. // HOLOTYPE [red] / Tyrodes jenisi / sp. n., Yin & Li / det. 2013.' (pvPH).

Description.

Male (Fig. 1A). Length 1.84 mm. Head about as long as wide, HL 0.37 mm, HW 0.36 mm; eyes each composed of about 35 facets; maxillary palpi as in Fig. 1E; antennae (Fig. 1B) elongate, scapes (Fig. 1D) triangularly projecting basolaterally, antennomeres II–VIII successively shorter; terminal three antennomeres enlarged (Fig. 1C). Pronotum about as long as wide, PL 0.39 mm, PW 0.38 mm, with rounded lateral margins, evenly narrowed apically at middle. Elytra wider than long, EL 0.55 mm, EW 0.77 mm. Legs lacking spines or projections. Abdomen broad at base and narrowed apically, AL 0.53 mm, AW 0.73 mm. Tergite VIII (Fig. 1F) and sternite VIII (Fig. 1G) transverse. Aedeagal length 0.24 mm, stout; with short, asymmetric median lobe (Figs 1H, I); endophallus composed of two sclerites curved to left.

Female. Unknown.

Comparative notes.

Tyrodes jenisi can be separated from all congeners, except for Tyrodes clavatus , by the distinct form of the aedeagus, as well as the consideration of distributional patterns.

Tyrodes championi is subequal in size (1.8 mm), but its aedeagal median lobe forms a distinct process at apex; Tyrodes histrio is smaller (1.5 mm), with the aedeagus being split at apex, and the endophallus with a long sclerite on the left side; Tyrodes janetscheki is greater in size (1.9 mm), its aedeagus has much more complicated structure of endophallus; Tyrodes segrex has a greater size as well (1.9-2.0 mm), and has clear different structure of aedeagal endophallus; Tyrodes setosus is subequal in size (1.8 mm), but the apical portion of aedeagal median lobe is curving to right, and has a strong apophysis on the right side. Aedeagus of Tyrodes clavatus has not been illustrated in any reference, but it is much smaller (1.4 mm), and is found in Singapore.

Comments.

In his world catalog of the genera of Pselaphidae , Raffray (1908) moved Pselaphodes clavatus Raffray, 1895 to Tyrodes , followed in the later Coleopterorum Catalogus ( Raffray 1911). Jeannel (1957: 32) compared the new species Tyrodes setosus Jeannel with Tyrodes clavatus when treating the pselaphines collected from Tonkin, Vietnam by Albert de Cooman. Besuchet (1970: 316), Newton & Chandler (1989: 60) and Kurbatov (1990: 145) also suggested or mentioned the placement of clavatus in Tyrodes . In the recent catalog of Tyrini ( Hlaváč and Chandler 2005), this placement was probably overlooked, the species was remained in the genus Pselaphodes . According to the original description, it is clear that clavatus belongs to Tyrodes .

Distribution.

Southwest China: Yunnan.

Etymology.

The new species is named after Ivo Jeniš ( Náklo, Czech Republic), collector of the holotype.
