Redescription.

Male. Head brownish, with dark brown markings; compound eyes grayish black, ocelli black with grayish black ocellar field; antennae and labrum brown, maxillary palpi brown with distal segments dark colored. Thorax brown with dark brown spots dorsally; legs pale brown, with tarsi dark brown. Fore wing (Fig. 1E) hyaline with yellowish tinge, pterostigma and veins brown, except for Rs fork and M-Cu1a fusion hyaline. Venation: Rs and M fused for short distance; distal margin of discoidal cell straight; first section of Cu1a little longer than the second section, diverging at angle about 120°. Hind wing hyaline; veins brown.

Abdomen. Male genitalia: 8th sternum strongly sclerotized and fused to hypandrium. Clunium (Fig. 6A) with posterior margin convex medially. Epiproct (Fig. 6AB) swollen, unsclerotized medially, with round projection at middle of anterior margin. Paraproct broad. Hypandrium (Fig. 6C) 5-lobed, lateral lobes carinate with outer surface covering denticles; posteromedian lobe forming dorsal-curved structure, with distal margin convex tapering to point; internal lobes tortuous forming right-angle and distally not forked. Phallosome (Fig. 6D) free posteriorly, distally broadened and paired with parameres.

Female genitalia: Subgenital plate (Fig. 6E) with egg guide round distally, basally invaginated and sclerotized at basal 1/3; pigment arms forming flat V-shaped regions and expanded laterally. Gonapophyses (Fig. 6F) with ventral valve distally tapering to slender tip; dorsal valve long and narrow with pointed distal process; outer valve oval, with posterior lobe narrow and well pointed. Internal plate (Fig. 6G) with brown coloration around spermathecal opening and marginally, with rod-like dark brown sclerotization anteriorly.

Measurements.

Male: Body length 2.1-2.9 mm; fore wing length 2.6-3.6 mm; hind wing length 2.0-2.7 mm. Female: Body length 2.6-3.3 mm; fore wing length 3.1-3.8 mm; hind wing length 2.4-2.9 mm.

Distribution.

China (Anhui, Fujian, Guangxi, Guizhou, Hunan, Jiangxi, Shaanxi, Shanxi).

Discussion.

These three species were very similar according to Li (1990, 2002). Neopsocopsis flavida was described based on the holotype specimen from Huaxi (Guiyang), with distribution range in central and southeast China. Blastopsocidus pini was described based on specimens from Bagongli (Guiyang), and could be differentiated from Neopsocopsis flavida by the fore wing veins M<M1+2 and by a smaller outer valve of the gonapophyses (Li, 1990). In 2002, Li described Pentablaste lanceolata based on 3 males which were formerly named under Blastopsocidus pini , with different character states of the postclypeus, paraproct and parameres. By our reexamination of all these species, there are only minor differences among Neopsocopsis flavida , Blastopsocidus pini and Pentablaste lanceolata , and it is hardly possible to distinguish them from each other by the genitalic characters. Therefore, we consider Blastopsocidus pini and Pentablaste lanceolata to be new junior synonyms of Neopsocopsis flavida . The species is distinguished from the other species by the posteromedian lobe of the male hypandrium convex tapering to a point, by the pigmented pattern of the female subgenital plate and by the narrow dorsal valve of the gonapophyses.
