( Figs. 6 View FIGURES 1–6 , 12 View FIGURES 7–12 , 22 View FIGURES 17–22 , 28 View FIGURES 23–28 , 34 View FIGURES 29–34 , 40 View FIGURES 35–40 , 46 View FIGURES 41–46 , 52 View FIGURES 47–52 , 58 View FIGURES 53–58 , 64 View FIGURES 59–64 )
Material examined. Holotype: apterous male, CHINA, Anhui Prov., Anqing city, Yuexi County, Yaoluoping Nature Reserve , 20 July 2012, Zhen Ye leg. ( NKUM) . Paratypes: CHINA, Anhui Prov.: 2 apterous males, 1 apterous female, same data as holotype ( NKUM) ; CHINA, Henan Prov.: 1 apterous male, 1 apterous female, Xinyang city, Jigongshan Nature Reserve , 27 August 2014, Zhen Ye leg. ( NKUM) .
Diagnosis. P. zhengi sp. nov. is similar to P. taiwanensis Ye, Polhemus & Bu, 2013 and P. sichuanensis Ye & Bu, 2015 . However, P. zhengi sp. nov. can be distinguished from P. taiwanensis by its relatively longer body ( P. zhengi sp. nov. 2.26–2.31 vs. P. taiwanensis 2.05–2.09) and more slender abdominal segment VIII (i.e., about 2.31 times as long as wide, Figs. 40 View FIGURES 35–40 , 46 View FIGURES 41–46 ), whereas abdominal segment VIII of P. taiwanensis is about 1.96 times as long as wide. In addition, compared with P. taiwanensis , the medial portion on the venter of the fore tibia of P. zhengi sp. nov. has a distinct process. This species can be distinguished from P. sichuanensis by the hind margin of abdominal segment VIII without some distinct specific modifications (e.g., distinct laminar processes) ( Figs. 40 View FIGURES 35–40 , 46 View FIGURES 41–46 , 52 View FIGURES 47–52 , 58 View FIGURES 53–58 ). Moreover, the abdomen of P. zhengi sp. nov. is more slender than the abdomen of P. sichuanensis , and the end of the abdomen of P. zhengi sp. nov. does not have dense, short hairs compared to that of P. sichuanensis .
Description. Apterous male ( Fig. 6 View FIGURES 1–6 ). Color: ground color yellowish-brown, head brown, clypeus brown, rostrum yellowish-brown with black apex, buccula red-brown; antennal segment I yellowish-brown, apical part infuscated, segments II–IV brown; pronotum yellowish-brown, with dense black spots on posterior part, lateral part of metanotum yellowish-brown; legs ( Figs. 22 View FIGURES 17–22 , 28 View FIGURES 23–28 , 34 View FIGURES 29–34 ) mainly yellowish-brown, femora yellowish, apices of femora infuscated, tibiae and tarsi brown, grasping combs brown; mediotergites dark-brown, connexiva yellowish-brown, lateral part of mediotergite I, medial parts of mediotergites II, III, VI and VII with prominent silvery pubescence; abdominal segment VIII ( Figs. 40 View FIGURES 35–40 , 52 View FIGURES 47–52 ), pygophore ( Fig. 64 View FIGURES 59–64 ) and proctiger yellowish, each of them weakly infuscated apically. Structural characteristics: body small-sized, bearing short and grayish setae, area around eyes and antennal segment I covered by relatively few, longer, grayish setae. Head short and wide, relatively perpendicular to thorax, without inflection; buccula clearly visible, but not produced posteriorly; eyes bare except for the presence of two ocular setae. Pronotum relatively broad, bearing dense, dark punctures on the posterior portion of lobe, hind pronotal margin nearly straight, anterior margin slightly emarginated; metanotum completely hidden beneath pronotal lobe except laterally. Fore tibia ( Fig. 22 View FIGURES 17–22 ) covered with dense, short setae, medial part of venter on fore tibia with process, grasping comb relatively thin; middle leg ( Fig. 28 View FIGURES 23–28 ) slender, tibia covered with dense, suberect, slender setae; hind femur ( Fig. 34 View FIGURES 29–34 ) slightly stout, tibia with suberect, needle-like setae, basal part of venter on hind tarsal segment I with a tuft of long, black bristles ( Fig. 34 View FIGURES 29–34 ), ventral arolium bristle-like. Abdomen almost flat, connexiva slightly raised, with suberect, few, short and brown setae; abdominal venter flat. Genital segments: relatively small, abdominal segment VIII ( Figs. 40 View FIGURES 35–40 , 46 View FIGURES 41–46 , 52 View FIGURES 47–52 , 58 View FIGURES 53–58 ) relatively slender, tubular-like, about 2.31 times as long as wide, hind margin with dense, short and brown hairs, ventrally with subtriangular depression, lateral margins of depression with a pair of short, brown setae, hind margin of depression with a pair of tiny processes with tufts of short, brown setae; lateral margin of pygophore ( Fig. 64 View FIGURES 59–64 ) with a pair of yellowish hairs, posterior part of pygophore with dense, yellowish hairs; proctiger subrectangular, with rounded apex; parameres symmetrical, small, stick-like, with rounded apex.
Apterous female ( Fig. 12 View FIGURES 7–12 ). Color: similar to male. Structural characteristics: body medium-sized, relatively stout, slightly larger than males, structure of head including antenna as in male; fore tibia without grasping comb, hind tibia and tarsus not modified, venter of hind tarsal segment I without a tuft of bristles; abdomen pleurally and ventrally without special modifications, connexiva relatively broad, slightly raised, converging posteriorly and touching caudally; gonocaxa I elongate, proctiger yellowish-brown, with dense, short, brown setae.
Macropterous female and macropterous male: unknown.
