Liu, Luxi, Yoshizawa, Kazunori, Li, Fasheng & Liu, Zhiqi, 2013, Atrichadenotecnum multispinosus sp. n. (Psocoptera: Psocidae) from southwestern China, with new synonyms and new combinations from Psocomesites and Clematostigma, Zootaxa 3701 (4), pp. 460-466 : 462-464

Atrichadenotecnum multispinosus sp. n.

Male. Coloration (in alcohol). Body generally brown. Compound eyes grayish black; ocelli brown with dark brown ocellar field. Rest of head brown with dark brown markings. Antennae dark brown except scape, pedicel and first flagellar segment yellowish. Maxillary palpi dark brown. Thorax dark brown, with membranous regions paler. Legs brown, with margin of femora, distal part of tibiae, and tarsi dark brown. Fore wing ( Fig. 1 ) hyaline with brown markings; basal region dark brown; nodal band continuous, without distinct spots; pterostigma entirely pigmented, without hyaline spots basally; submarginal markings continuous, ranging from cell R3 to middle of areola postica. Hind wing ( Fig. 2 ) hyaline with pale brownish along anterior margin; veins brown except in basal regions white. Abdominal segments creamy brown, with brown irregular markings; apical regions dark brown.

Morphology. Fore wing membranous, glabrous; Sc ending free in membrane, Rs and M fused for a distance, slightly shorter in length than 1st section of Rs; pterostigma triangular with apex moderately rounded; distal closure of discoidal cell concave; areola postica triangular, with short roof almost of equal length as roof of cell M3; radial fork branches diverge at an angle less than 90°. Hind wing without marginal setae between R2+3 and R4+5. Phallosome ( Figs. 3, 4 ) much longer than wide, gradually tapered apically, its left margin almost straight and right margin strongly curved to the left, apex with tiny projections. Hypandrium ( Figs. 5, 6 ) almost symmetrical, with five developed spines dorso-medially (two in left and three in right); pair of serrated ventral projections strongly projected dorso-laterally; distal margin with pair of processes bearing with fine spines. Clunium ( Fig. 7 ) with dorsal margin straight and slightly extended posteriorly. Epiproct ( Fig. 7 ) with almost straight posterior margin, unsclerotized medially; paraprocts broad, with a strong apical spine, sensory fields with about 28 trichobothria.

Measurements. Bw: 3935, B: 2267, FW: 3233, HW: 2367; F: 573, T: 1253, t1: 393; t2: 146, f1: 492, f2: 372, f3: 338, Mx4: 121, IO/d: 705.

Female unknown.

Material examined. Holotype male, CHINA: Guizhou Province, Kuankuoshui Nature Reserve, 13.viii.2010, Luxi Liu (CAU).

Etymology. The species name refers to the prominent developed spines on the hypandrium.

Remarks. The new species appears to be closely related to Atrichadenotecnum nudum (Thornton, 1961) and A. ryukyuense Yoshizawa, 1998 , but can be distinguished from the two species by hypandrium characters with five strong spines dorso-medially.
