Cenocorixa montana sp. nov.

( Figs. 11–14 , Fig. 17)

Description: Measurements: Male: Length of body 5.1, width of body 1.8; length of head 0.32, width of head 1.8, width of an eye 0.6, interocular space 0.7; length of pronotum 0.8, width of pronotum 1.6; length of pala 0.55, width of median 0.26; length of front tibia 0.25, length of front femur 0.7; length of segments of mesoleg: femur: tibia: tarsus: claw = 1.70: 1.0: 0.6: 0.8. length of forewing 4.2, length of claval suture 2.2, length of pruinose area of claval suture 0.9, length of prenodal pruinose area of embolium 1.7, length of postnodal pruinose area of embolium 0.74. Female: Length of body 5.3, width of body 2.1; length of head 0.4, width of head 1.9, width of an eye 0.7, interocular space 0.8; length of pronotum 0.9, width of pronotum 1.6; length of forewing 4.3.

Color: Body brown, with yellowish patterns, head dark yellow, transverse bands on pronotum yellow, chorion, and membrane separated by a pale line, mesosternum and metaxyphus fuco-piceous, abdomen ventral yellowish but male’s basal 3 segments fuscous.

Structural Characteristics: Vertex broad and rounded in both sexes, face of male a little flat; pronotum rugose; 7–8 bands on pronotum, sometime incontinuous or bifurcate, slightly wider than dark interspaces; lateral angles of pronotum rounded; lateral lobes of prothorax gradually narrow towards end, apex obtuse ( Fig. 11 -a); metaxyphus triangular, wide almost equal to long, apex obtuse; male pala broad, with a curving peg row consisting of 29 pegs, peg row interrupted at oblique ridge crossing face of pala, 13 anterior and 16 posterior ( Fig. 12); forewing brightness, with procumbent hairs, patterns small and with low contrast; clavus rugose, anterior part of clavus with 6–7 regular bands, the posterior part and corium with vermiculate patterns; strigil subrounded, of medium size, consisting of 5–6 combs ( Fig. 14); median setiferous lobe of 7th abdominal tergite well developed, triangular, slightly curved and apex rounded ( Fig. 13); apical 1/3 part of right paramere slim, with a tuber at its tip ( Fig. 11 -b); left paramere with blunt pegs as in Figs. 11 -c, d and 11- e.

Etymology: Named for the habitat of the new species.

Type: Holotype: 3, CHINA Yunnan (Mt. Fenghuang Nanjian) 2400m, 2001. VI.3. Wenjun Bu leg.; paratype: 33, 2ƤƤ, CHINA Yunnan (Mt. Fenghuang Nanjian) 2400m, 2001. VI.3. Wei Bing Zhu leg.. All types were deposited in NKUM.

Discussion: This new species is similar to Cenocorixa bifida (Hungerford) in the outline of the male pala, but the body smaller, the peg row is divided into two parts at the oblique ridge on the male pala; the right paramere is not bifurcated at its tip; the strigil is subrounded, consisting of 5–6 combs. All these characters can help to distinguish the two species.
