2. Pseudokuzicus (Similkuzicus) quadridentatus sp.nov.

(Figs. 13–18, 21)

Male (figs. 13–17, 21). Body very similar to Pseudokuzicus longidentatus Chang, Zheng & Wang, 1998 . Fastigium of vertex conical, apex faintly obtuse, with thin longitudinal furrow. Compound eyes round, protruding obviously. Apical segment of maxillary palpi distinctly longer than subapical one, apex strongly enlarged. Pronotum with almost straight anterior margin, posterior margin angularly rounded, prolonged backwards and covered stridulatory area of tegmina, metazona flattened; lateral lobe longer than high (length 2.5mm, height 1.5mm), both anterior and posterior margins oblique, humeral sinus absent. Thoracic auditory spiracle comparatively small. Anterior coxa with a spine, anterior tibia with 2 internal and 3 external spines and 1 apical spur on both ventral margins, tibial tympana free on both sides; posterior femur strong, posterior tibia with 19–22 spines and a pair of apical spurs both on ventral and dorsal margins. Tegmina abbreviated, not reaching apex of posterior femur, but slightly exceeding abdominal apex, hind wings shorter than tegmina. Tenth abdominal with a pair of colliculose processes in middle. Cerci rather similar to Pseudokuzicus longidentatus , separated into external and internal processes, internal one with thin apex, external process longer than internal one. Titillator sclerotized obviously, comparatively small, apex with four thin teeth. Subgenital plate relatively large, posterior margin slightly narrow, with triangular medial notch. styli absent.

Female (fig. 18). Cerci conical, apex acute. Ovipositor stout at base, moderately curved upward in apical half, ventral valvulae slightly longer than dorsal one, apices hooked. Subgenital plate widen in the middle.

Coloration. Body multicolor (see figs C–D). Frons, clypeus and labrum black brown. Inner raised margin of antennal foveola with black edge. Dorsum of head with two irregular longitudinal dark brown stripes, behind the inner side of compound eye with a small dark brown spot. Several basal segments of antennae brown, other segments with some brown ring stripes. Pronotum light yellow in prozona and with two dark brown spots on lateral lobes; metazona slightly dark with a pair of black brown spots on lateral area. Antenna, anterior and medial legs and posterior femura with irregular brown stripes. Tegmina brown, with some irregularly dark brown spots. Basal half cerci yellowish brown, apical half blackish brown.

Type material. Holotype: male, China: Lianhuaping, Leigongshan, Leishan , Guizhou Province, 14. Sept. 2005, collected by Liu Hao-Yu . Paratype: 1 male, 1 female, 15. Sept. 2005, orther data same to holotype.

Measurements (in mm). Length of body: ♂ 7.0–8.0, ♀ 7.0; Length of pronotum: ♂ 3.8, ♀ 4.5; Length of tegmina: ♂ 5.0–6.0, ♀ 6.5; Length of hind femora: ♂ 8.0–8.5, ♀ 9.0; Length of ovipositor: 5.5.

Etymology. The specific name comes from titillator morphology.

Diagnosis. This new species is very similar to P. (P.) longidentatus Chang, Zheng & Wang, 1998 , it is different from the latter in: (1) Male tenth abdominal tergite with a pair of colliculus-shaped processes; (2) Titillator with four teeth at apex; (3) Male subgenital plate broader in distal third.
