Compsidolon pilosum, Li, Xiao-Ming & Liu, Guo-Qing, 2014

Li, Xiao-Ming & Liu, Guo-Qing, 2014, A study on the genus Compsidolon Reuter, 1899 from China (Hemiptera: Heteroptera: Miridae: Phylinae), with descriptions of three new species, Zootaxa 3784 (4), pp. 469-483 : 479-480

Compsidolon pilosum sp. nov.

( Figs. 13–14 , 23 , 48–51 )

Type specimens. Holotype: Male (photographed), CHINA: Lixian County (24°44'N, 100°54'E), Sichuan Province, alt. 3150m, 4.VIII.1963, Le-Yi ZHENG leg.. Paratypes: 10 males, 10 females (one of them photographed), same data as holotype. (The type specimens are deposited in the Institute of Entomology, Nankai University, Tianjin, China)

Diagnosis. Moderately large size, range total length 4.00–4.66; head, pronotum, hemelytra and scutellum with dark spots; frons with dark brown radial stripes; antennal segment I with a black ring at base and two or three black marks at the middle; interocular distance wider than width of eye; cuneus with obvious dark spots; all tibiae obviously darkened at base; body of endosoma slender, sigmoid, apex fork-shaped, secondary gonopore removed from apex of endosoma ( Fig. 48 ). Similar to C. uncum , in sharing dark spots near the posterior margin of vertex and coloration of dorsum somewhat reddish, but they can be easily separated by the the structure of endosomae. Similar to C. eximium in shape of endosomae, apex fork-shaped, but in C. pilosum , secondary gonopore farther from the apex of endosoma. In addition, the interocular distance shorter than width of eye in male and cuneus without obvious dark spots in C. eximium .

Description. Male ( Fig. 13 ): Total length 4.52–4.66, elongate ovoid.

Coloration: General coloration yellowish brown, somewhat reddish; antenna dark yellow, segment I with a black base; eye reddish brown; labium yellow, dark distally; pronotum with dark spots, calli pale; exposed part of mesoscutum orange-red; apex of scutellum black; hemelytra yellowish brown, clavus and corium with clear dark spots, cuneus reddish, pale at base, and with obvious dark spots, membrane fumose, with big pale marks; legs dark yellow, femora somewhat reddish with black spots; all tibiae obviously darkened at base, tibial spines dark with black base; tarsus and claw darkened; abdomen yellowish brown with golden setae.

Suface and structure: Dorsum smooth, dull to weakly shining; vestiture composed of recumbent, dense, dark, simple setae and silvery setae; head declining; clypeus not visible in dorsal view; frons and vertex slightly convex in lateral view; interocular distance wider than width of eye; eyes almost occupying entire height of head in lateral view; antennal segment II greatly longer than width of pronotum; labium reaching to posterior margin of hind coxae; hemelytra nearly parallel-sided, weakly deflexed at cuneal suture; membrane relatively developed and veins obvious; metathoracic scent-gland evaporative area as in Fig. 23 ; genital capsule large relative to total size of abdomen.

Male genitalia ( Figs. 48–51 ): Endosoma slender, sigmoid, apex fork-shaped, near the apex of endosoma twisting, secondary gonopore far from apex of endosoma; left paramere boat-shaped; right paramere lanceolate; phallotheca attenuated apically as in Fig. 47 .

Female ( Fig. 14 ): Total length 4.00–4.05. Smaller than male, more ovoid, general coloration similar to male. Distribution. China (Sichuan).

Etymology. Named for its dense body hair, from the Latin “ pilosum ”, meaning comous.
