Compsidolon flavidum, 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 : 475-477

Compsidolon flavidum sp. nov.

( Figs. 5–6 , 22 , 32–35 )

Type specimens. Holotype: Male (photographed), CHINA: Naxi Autonomous County of Lijiang (27°06'N, 100°15'E), Yunnan Province, 11.VIII.1979, Huan-Guang ZOU leg.. Paratypes: 3 males, 5 females (one of them photographed), same data as holotype; 3 males, 2 females, same data as holotype, 12.VIII.1979, Guo-Qing LIU leg.. (The type specimens are deposited in the Institute of Entomology, Nankai University, Tianjin, China)

Diagnosis. Moderately large size, total length 4.32–4.46; frons and pronotum without spots; hemelytra (except cuneus) and scutellum with dark spots; antennal segments I and II with black rings at bases; labium relatively long, reaching abdomen; tibiae with black base; endosoma with two apical spines, one slender and straight, and other shorter, weakly bent ( Fig. 32 ). Body structure similar to C. uncum and their endosoma sigmoid with two apical spicules, but in C. uncum frons with reddish brown radial stripes and pronotum with dark spots, and endosoma of uncum much bigger than in C. flavidum . Similar to C. cytisellum (Lindberg, 1953) in sharing frons and pronotum without obvious spots, but they can be easily separated by the coloration of antenna, with antennal segments I and II in C. cytisellum without black rings at base.

Description. Male ( Fig. 5 ): Total length 4.35–4.46, elongate ovoid.

Coloration: General dorsal coloration yellow; antenna yellow, segments I and II with black rings at base; apex of clypeus black; labium pale, infuscate apically; pronotum yellow without any spots; exposed part of mesoscutum yellow; scutellum yellow, apex slightly darkened; hemelytra light yellow, clavus and corium with dark spots, cuneus usually pale without spots, membrane pale with big dark marks; legs usually yellow, femora with black spots, and apically with two black spines on dorsal surface; tibial spines black with black spots at base, several rows of black spinules on hind tibiae, tibiae pale at base; tarsal segment III and claw darkened; abdominal venter yellow with golden yellow setae.

Suface and structure: Dorsum smooth, weakly shining; vestiture of dorsum composed of recumbent, black, simple setae and golden setae; head declining; clypeus not visible in dorsal view; frons projecting well beyond anterior margin of eyes, broadly transversely rounded in dorsal view; posterior margin of vertex straight; interocular distance longer than width of eye; eyes occupying nearly total height of head in lateral view; antenna inserted below ventral margin of eye, antennal segment II longer than width of pronotum; labium reaching abdomen; callus clear; hemelytra nearly parallel-sided, slightly deflexed at cuneal suture; claws slender and small, weakly curving; metathoracic scent-gland evaporative area as in Fig. 22 ; gentital capsule occupying about 1/3 of the length of abdomen.

Male genitalia ( Figs. 32–35 ): Endosoma sigmoid, body relatively heavy, base falling well below level of secondary gonopore, two apical spines at the endosoma, one slender and straight, the other shorter, weakly bent; left paramere boat-shaped; right paramere lanceolate; phallotheca bending as in Fig. 35 .

Female ( Fig. 6 ): Total length 4.32–4.43. Very similar to male, but body more ovoid.

Distribution. China (Yunnan).

Etymology. Named for its general coloration, from the Latin “flavidus”, meaning yellow.
