Anatlanticus longispeculi Liu sp. n.

( Fig. 2 C, G; Fig. 3 C; Fig. 4C; Fig. 5C, G, M)

Holotype. male [IOZ(E)1340197]. China: Jinlin Prov.: Manjiang, 1955. VII.31, Coll. Li Zhiying.

Diagnosis. Small-sized compared to the species in the genus Mongolodectes . Male tegmen extending beyond caudal margin of the seventh tergum when contracted ( Fig. 2 C,G). Tenth abdominal tergum with an elliptical notch in apical half; apical one-third part of two lateral apical lobes strongly curved outwards (Fig. 5C). Epiproct narrow, triangular (Fig. 5C). Cerci short, robust, slightly narrowed backwards; apex with neighboring inner tooth and apical hook, and the latter shorter than the former (Fig. 5G). Subgenital plate narrow long; apical margin with a shallow trapezoidal notch between styli, notch much shorter than stylus (Fig. 5M).

Description. Fastigium of vertex slightly shorter than first antennal segment; dorsally with a shallow median sulcus. Compound eyes subcircular. Disc of pronotum with slightly concaved anterior margin and widely round posterior margin. Disc of prozona slightly convex, with smooth lateral margins; metazona approximately flat, with obvious lateral carinae. Disc of prozona approximately equally wide; metazona abruptly ampliate caudad from proximal part. The first transverse sulcus lying at anterior one fifth, and central transverse sulcus shallow, Ushaped. Lateral lobes of pronotum longer than high. Tegmen amplified, deepened, with clear longitudinal and cross veins; twice longer than pronotum; apex round ( Figs. 2 C,G). 2/3 basal part of stridulatory file on underside of left tegmen with 50 distinct stridulatory teeth. These teeth are middle-spaced arranged and gradually becoming larger centrad ( Fig. 3 C). Mirror on right tegmen heart-shaped, slightly longer than wide (Fig. 4C).

Fore coxae armed with a sharp spine. Fore femur with 0-1 interior ventral spines. Middle femur without spines. Hind legs lost. Fore tibiae with 6 ventral spines on both margins and 3 dorsal exterior spines. Middle tibiae with 6 ventral spines on both margins, 2 dorsal exterior spines and 4 dorsal interior spines.

Coloration. Generally testaceous with exception of golden tegmen. Face, gena, compound eyes and upper portion of compound eyes, a narrow stripe along ventral margin of lateral lobes of pronotum, coxae and trochanter generally slightly yellow. Following parts shining dark testaceous: antennae, apex of fastigium of frontis, postocular fascia, disc of pronotum except a pair of yellowish blotches on base of metazona, lateral lobes of pronotum except a comparatively narrow fascia, disc of prozona, meso- and metanotum, dorsal exterior surface of fore femur, and abdomen. Inner margin of fore femur yellowish with five discontinuous black central spots. Median femur yellowish with numerous black dorsal and central spots. Tibiae yellowish, base of spines black. Tegmen golden, with exception of about proximal three quarters part of subcostal, radial and medial veins dark brown.

Female unknown.

Etymology. The name is named for the comparatively long speculum of male.

Notes. The specimen of the type species A. uvarovi is not available and not examined. From the original description and illustration of A. uvarovi ( Miram, 1940) , it clearly shows that characteristics of male cerci and mirror on right tegmen. The male cerci possess one inner and one apical spine, both which extend outwards to similar extent, although the inner spine is smaller than apical one. In addition, the mirror of A. uvarovi is obviously wider than long. By contrast, the inner spine is larger than the apical one for the new species A. liaoningensis sp. n.. It also differs from A. uvarovi by the mirror which is obviously as long as wide.
