Type materials.
Holotype: China • ♂; Yunnan, Yaonan Village, Mt Ailaoshan, Xinping County, Yuxi City; 12.V.2016; Lu Qiu & Zhiwei Qiu leg.; SWU-B-BL-082901. Paratypes: China • 3♂♂, 2♀♀; Yunnan; Yaonan Village, Mt Ailaoshan, Xinping County, Yuxi City; 11-12.V.2016; Lu Qiu & Zhiwei Qiu leg.; SWU-B-BL-082902 to 082906.
Diagnosis.
Combining the following characteristics, this species is easily distinguished from other Blattinae species: 1) pulvilli developed, pulvilli of front metatarsus occupy nearly 1/3 of ventral surface; 2) supra-anal plate short; 3) L4C curved and subhyaline, the base irregular; 4) the distal part of R1G with two curved and strong spines; 5) female tegmina small, lobe-like, and hind wings absent.
Description.
Sexual dimorphism present. Coloration. Body dark brown to black; vertex black; ocelli white; tegmina dark yellowish brown (Fig. 6A-D View Figure 6 ).
Male (Fig. 6A, B View Figure 6 ). Body length including tegmen: 28.5-30.1 mm; body length: 19.6-21.4 mm; pronotum length × width: 4.2-4.7 mm × 5.7-6.7 mm; tegmina length × width: 24-26.6 mm × 6.4-7.8 mm. Head and thorax. Vertex slightly exposed. Interocular space slightly wider than the interocellar space, slightly shorter than the distance between antennal sockets (Fig. 6E View Figure 6 ). Antennae longer than the body. Pronotum subelliptical; anterior margin straight, hind margin slightly convex; the widest point near the midpoint (Fig. 6F View Figure 6 ). The posterior-lateral angles of metanotum without finger-like projections (Fig. 6K View Figure 6 ). Tegmina and wings well developed, surpassing the tip of abdomen (Fig. 6 A, B, G, H View Figure 6 ). Tegmina with ScP strong, posterior branch of R not reaching the end of tegmina (Fig. 6G View Figure 6 ). Front femur of type A2 (Fig. 6I View Figure 6 ). Hind metatarsus equal to the remaining segments combined (Fig. 7D View Figure 7 ). Pulvilli present, pulvilli of front metatarsus developed, pulvilli of front metatarsus occupy nearly 1/3 of ventral surface (Fig. 6J View Figure 6 ). Claws symmetrical and unspecialized, arolium moderate (Fig. 7D View Figure 7 ). Abdomen. First tergite of male abdomen with visible gland, setose gland not obscured by metanotum and grown upward and downward (Fig. 6K View Figure 6 ). Posterolateral corners of abdominal tergite V-VII produced. Supra-anal plate short, lateral margin slightly shrunken inward; middle part of hind margin concave at an obtuse angle. Paraprocts (pp.) long, strip-shaped, the end curved downward. Cerci long and robust (Fig. 6L View Figure 6 ). Subgenital plate nearly square; the hind margin straight. Styli symmetrical and apically rounded (Fig. 6M View Figure 6 ). Genitalia (Fig. 6N View Figure 6 ). L1 membranous and irregular, margin thick. L4C curved and subhyaline, the base irregular. L2 irregular and folded, the dorsal sclerite broad, the distal part with a long spine. L3 unciform and well sclerotized, the basal part bifurcated. L4G strip-like. R1H slightly broad, inner margin of the distal part with two strong spines. The distal part of R1G with two curved, strong spines inward.
Female (Fig. 5C, D View Figure 5 ). Body length: 17.9; pronotum length × width: 5.4-5.6 mm × 7.9-8.0 mm; tegmina length × width: 3.5-3.7 mm × 2.3 mm. Head and thorax. Pronotum subelliptical, the widest point near hind margin; anterior margin curved, hind margin nearly straight (Fig. 6C View Figure 6 ). Tegmina and wings reduced. Tegmina small, lobe-like (Fig. 6C View Figure 6 ). Pulvilli present, pulvilli of front metatarsus developed, pulvilli of front metatarsus occupy nearly 1/3 of ventral surface (Fig. 6J View Figure 6 ). Claws symmetrical and unspecialized, arolium moderate (Fig. 7D View Figure 7 ). Abdomen. Hind margin of tergum X (TX) with median invagination, and with a membranous line inside (Fig. 6O View Figure 6 ). Genitalia (Fig. 6O View Figure 6 ). The surface of first valve (v.I.) with small punctures. First valvifer (vlf.I) slightly sclerotized and hyaline. Posterior lobes of valvifer II (p.l.) irregular, the outer margin unclear. Laterosternite IX (ltst.IX) slightly sclerotized and hyaline. Anterior arch (a.a.) with microtrichia near basal surface. Spermathecal plate (sp.pl.) nearly triangle. Spermathecal opening (sp.o.) located at the base of basivalvulae (bsv.). Spermatheca branched, the leading duct longer than the branching duct, and the branching duct also branched, the end capsule oval (Fig. 7E View Figure 7 ). Basivalvulae broad, surface with microtrichia; the left and right basivalvulae connected. Laterosternal shelf (ltst.sh.) symmetrical.
Etymology.
The species epithet is from the Latin word " crassispinus ", in reference to the two strong spines on the distal part of R1G.
