Pherolepis longipilus sp.nov.

( Figs. 6, 7 , 37–48 )

Type specimens: Holotype: male, CHINA: Tianjin Municipality (39°02'N, 117°12'E), alt. 50m, 1. VII. 1994, Nan Lu leg.. Paratypes: 2 females, same data as holotype; 2 males, 1 female, same data as holotye except for date, 18. V. 1994; 1 male, CHINA: Fengxian County (33°55'N, 106°31'E), Shaanxi Province, alt. 1400m, 27. VII. 1994, Wen-jun Bu leg.; 2 males, 2 females, CHINA: Anyang City (36°6'N, 114°21'E), Henan Province,?. V. 1954.

Diagnosis: Recognized by the distinctively long, dense, erect or suberect, deep brown simple setae covering the dorsal surface of the body ( Figs. 6, 7 , 39, 40 ), the shining sericeous setae densely scattered on the proximal 2/3 of hemelytron, the yellow-brown hemelytron, the castaneous head, pronotum and scutellum. Most similar to P. amplus Kulik ( Figs. 3, 4 ) in size and coloration of dorsum, but distinguished by the structure of male genitalia ( Figs. 43–47 ) and the presence of extremely long simple setae ( Figs. 37, 39–40 ).

Description: Male ( Fig. 6 ): Macropterous, oval, medium-sized.

Coloration: General coloration yellowish brown or brown, without distinctive colored markings on dorsum; head, pronotum, exposed part of mesoscutum and scutellum castaneous to almost black; membrane fumose, without spots; eyes dark brown with outer margin reddish; antennal segment I and proximal half of segment II dirty yellow, distal half yellow-brown to castaneous, segment III and IV castaneous to black; clypeus and buccula reddish brown; labium yellowish brown; coxae and trochanter pale-yellow, femora and tibiae pale-brown, tarsal segment III blackish brown; abdomen dark brown.

Surface and Vestiture: Dorsal surface of body covered densely with two types of setae, distinctly long, erect or suberect, simple setae ( Figs. 37, 39–40 ) and decumbent or appressed, flattened, shining sericeous setae.

Structure: Head ( Fig. 37 ): Triangular in frontal view and transverse in dorsal view, weakly convex posteriorly; vertex and frons moderately inclined, densely covered with two types of setae mentioned above, posterior margin of vertex forming a complete, weakly rounded carina; frons and clypeus distinctly protrudent, easily visible in dorsal view; mandibular and maxillary plates, and buccula covered with sparse, recumbent, simple setae; labium elongate, almost reaching posterior margin of hind trochanter; eyes broadly ovoid; antennal segment I short and stout, narrow at base, segment II long, tubular and weakly curved; segment III equal to segment IV in diameter and length, more slender than segment II. Thorax: Pronotum broad, weakly tumidiform, anterior and posterior lobes not demarcated, posterolateral angles rounded, posterior margin slightly concave; mesoscutum broadly exposed, weakly declining; scutellum slightly swollen mesially; hemelytron broad, clavus weakly elevated along the claval commissure; cuneus broadly triangular, moderately declining; veins of membrane indistinct; femora stout and somewhat flattened, tibiae cylindrical and straight, with two rows of black short spicules; tarsal segment I and II subequal in length, segment III about two times length of segment II; claws distinctly curved, slightly broadened basally, pulvilli absent, parempodia lamellate, recurved, and convergent apically. Abdomen: Relatively stout and broad, generally covered with recumbent, pale simple setae.

Male genitalia ( Figs. 43–47 ): Vesica typically L-shaped, with a large, flattened, spinelike projection on shaft, near apex with a fingerlike process, apex of vesica with broad membrane ( Fig. 43 ); left paramere boatshaped, hypophysis elongate, sensory lobe blunt ( Figs. 44, 45 ); right paramere leaflike ( Fig. 46 ); phallotheca elongate, apex weakly curved ( Fig. 47 ).

Female ( Fig. 7 ): Macropterous. Surface and coloration similar to male, the size weakly bigger than male, body broader.

Female genitalia: Structure as figure 48.

Distribution: China (Nei Mongol, Tianjin, Henan).

Host: No data available.

Etymology: Named for the distinctly dense, long, erect or suberect setae on dorsum.
