Diagnosis.

Medium-small-sized species for the subgenus ( BL = 6.3–7.8 mm), BW = 2.5–3.2 mm; elytra with microsculpture linear in both sexes; antennomeres 3 without accessory setae; pronotum nearly quadrate, lateral margins subparalleled behind middle; basal foveae usually with a few fine punctures along inner sulcus and basal margin; outer sulcus shallow and short, inner sulcus usually closer to median line than to lateral margin; elytral humeral tooth sharp, apex distinctly hooked backwards; interval 3 with two setigerous pores, all adjacent to stria 2, first pore positioned near middle of elytra, the other one near apical fourth; fifth tarsomeres with two or three pairs of setae ventrally; male sternites without sexual modification. Apical lamella of aedeagus short and wide, with very small lamellar denticle; ventral surface of median lobe sharply ridged. Gonocoxite 2 of female ovipositor small, widely crescent-shaped, outer margin with two or three large ensiform setae, dorsal margin not ridged, with an ensiform seta near apical third.

Comparisons.

This species can be readily differentiated from all other species from Hubei by the relatively small body size; body form subparallele; elytral interval 3 with two pores, all adjacent to striae 2; fifth tarsomere setose ventrally. It is only similar to the species described below, P. yaotiao sp. nov. Their comparisons will be provided under the description of the new species.

Compared with species not occurring in Hubei Province, P. hubeicus is most similar to P. janatai Sciaky & Wrase, 1997 which is distributed in Shaanxi Province. These two species share the following important characteristics: submentum with one seta on each side; pronotum nearly quadrate, not narrowed to base; elytral interval 3 with two setigerous pores, all adjacent to stria 2; median lobe of aedeagus with sharp ventral ridge, without a distinct lamellar denticle. However, P. hubeicus can be differentiated from P. janatai by the body size much smaller; basal foveae usually with punctures along inner sulcus; apical lamella of aedeagus wider and bent downward.

Description.

This species is easily recognizable and has been sufficiently described by Facchini and Sciaky (2003). A redescription is unnecessary here, except for the following supplementary descriptions on the endophallus (Fig. 19 A, B View Figure 19 ): Endophallus bent to right-dorsal side of aedeagus, major parts of endophallus located on dorsal side of aedeagus; gonopore opened to basal-dorsal direction of aedeagus; surface with very fine scales, densest near gonopore; gonoporal piece large and strongly chitinized, comma-shaped. Four distinct lobes recognized: basal lobe (bl) rounded, close to apical lamella, membranous without decoration; left pre-apical lobe (lp) large, protruding towards right side of aedeagus, membranous without decoration; left apical lobe (la) rounded, close to gonopore, with fine scales; right apical lobe (ra) relatively small, visible in both lateral views, decorated with coarse scales; three small but strongly chitinized pieces present near gonopore and base of ra.

Distribution.

This species is known from two localities: Shennongjia in Hubei and Wuxi in Chongqing, and is distributed at mid- to high altitudes of 1700–2500 m.
