Batriscenellus pengzhongi Jiang and Yin View in CoL , new species
( Fig. 7 View FIGURE 7 )
Type material (3 exs). Holotype: ♂: ‘ China: N. Guizhou, Daozhen Co. ( AEAH), Dashahe (XÒÑ), 29°10'12"N, 107°33'36"E, mixed leaf litter, sifted, 1730 m, 07.VII.2015, Jiang, Peng, Tu & Zhou leg.’ ( SNUC) GoogleMaps . Paratypes: 2 ♂♂, same collection data as the holotype (SNUC).
Diagnosis of male. Dorsal surface of head and pronotum finely punctate, tergite IV with sparse and shallow punctures; antennomeres subcylindrical; elytra with shallow sutural and discal striae; protibiae with small apical bunch of setae; tergite IV modified, with a distinct triangular tubercle at posterior portion, and two much smaller tubercles lateral to tubercle; aedeagus with suberect, and markedly elongate ventral and dorsal lobes.
Description. Male ( Fig. 7 View FIGURE 7 A). Body reddish-brown, length 2.18–2.24 mm. Head subrectangular, wider than long, HL 0.40–0.43 mm, HW 0.51–0.52 mm, dorsal surface finely punctate ( Fig. 7 View FIGURE 7 B); vertex lacking median ridge, U-shaped sulcus only indicated at anterior margin; antennomeres subcylindrical, clubs formed by apical three antennomeres; each eye composed of about 30 facets. Pronotum about as long as wide, PL 0.48–0.49 mm, PW 0.48–0.50 mm finely punctate ( Fig. 7 View FIGURE 7 B). Elytra wider than long, EL 0.74–0.76 mm, EW 0.82–0.83 mm, narrowed at base, shallow discal striae extending to apical 2/3 of elytral length; sutural striae complete. Protibiae with small apical bunch of setae. Abdomen wider than long, AL 0.48–0.49 mm, AW 0.48–0.50 mm, tergite IV ( Fig. 7 View FIGURE 7 C) with sparse and shallow punctures, with distinct triangular tubercle at posteromedian portion, and two much smaller tubercles lateral to tubercle. Aedeagus ( Fig. 7 View FIGURE 7 D–E) strongly asymmetric, length 0.38 mm, with elongate and erect ventral and dorsal lobes, ventral lobe laterally projecting near middle.
Female. Unknown.
Comparative Notes. At present, this new species cannot be placed in any known species groups within the genus. The unique presence of a distinct triangular tubercle on the posteromedian portion of male tergite IV, and the elongate and erect aedeagal ventral and dorsal lobes quickly separate B. pengzhongi from all other known congeners.
Distribution. China: Guizhou.
Etymology. The specific epithet is dedicated to Zhong Peng, co-collector of the type series.
