Redescription of male (lectotype): General colour reddish-brown with scattered small dark dots. Eyes and 5th (ultimate) segment of maxillary palps black. Scapi, mouthparts (with exception of 5th segment of maxillary palps) and legs dirty yellowish. Surfaces smooth and lustrous, distal parts of antennae (from 14th segments) dull; very weak punctuation present in tegmina. Head about as long as wide (Fig. 38); ocellar spots small; facial part globular, without impression or wrinkles between eyes; distance between eyes about as long as eye length; distance between antennal sockets about 1.7 times scape length (0.8 mm); approximate length ratio of 3rd-5th segments of maxillary palps 1.0: 1.0: 1.4. Pronotum as in Fig. 39. Tegmina strongly shortened, about as long as wide (Fig. 40), reaching 3rd abdominal tergite; venation obsolete, thickened Sc visible only on ventral side of tegmina, remnants of CuP discernible on dorsal side. Wings vestigial, completely hidden under tegmina. Fore tibiae not thickened distally. Anterior margin of fore femora of armed type B, with 4-5 spines, including 1-2 apical one. Tibial spines well developed. Structure of hind tarsi: metatarsus about as long as other segments combined; euplantulae of 1st-4th segments small and apical; metatarsus with 2 more or less equal rows of spines along lower margin; “additional spines” bordering euplantulae of 2nd-3rd segments from inside and outside present; claws symmetrical, simple; arolium small, less than half of claw length. Abdomen without glandular specializations. Anal plate (tergite X) partly membranous, trapezoidal in shape, caudal margin weakly concave, without medial incision (Fig. 41). Cerci short, with distinct segments. Paraprocts of blaberid-type (Fig. 42, par.). Hypandrium asymmetrical, caudal margin membranous, concave; right stylus flattened and weakly sclerotized, left stylus absent (Figs 43, 44).
Genitalia (Figs 46-55). Right phallomere (R+N): caudal part of sclerite R1T well sclerotized, subrectangular in shape, with rounded apex (Figs 46, 47, c.p.R1T), covered with bristles; R2 weakly curved; R3 subtriangular, widened caudally; R4 large, plate-like; R5 plate-like, situated in dorsal side of phallomere, partly covered with very small tubercles. Sclerite L2D (L1) divided into basal and apical parts (Figs 48-51); basal part rodlike, distinctly widened cranially (Fig. 48, b.L2D); “apical sclerite” densely covered with bristles; “dorsal outgrowth” large (Figs 49-52, d.o.); Sclerite L3 (L2d) small, with basal subsclerite, (Fig. 53, b.L3); “folded structure”, bristles, “apical crest” and groove hge absent. Sclerite L4U (L3d) large (Fig. 53).
Variation (paralectotypes): Antennae dull from 12th segments. Caudal margin of hypandrium more rounded, as compared with that of lectotype; left stylus present as very small vesicle (Fig. 45). “Dorsal outgrowth” of “apical sclerites” slightly vary in shape (Fig. 52, d.o.).
Redescription of female: Similar to male, but larger. Antennae dull from 11-12th segments. Head with distance between eyes 1.1 times eye length (Fig. 56); distance between antennal sockets about 1.6 times of the scape length (0.9 mm); approximate length ratio of 3rd-5th segments of maxillary palps 1.3: 1.0: 1.3. Pronotum and tegmen as in Figs 57, 58. Anal plate transverse, caudal margin widely rounded with weak medial incision (Fig. 20). Cerci shortened, as compared with male (Fig. 20). Genital plate as in Fig. 21.
Ovipositor and adjacent structures (Figs 22, 23): Intercalary sclerite absent; tergal processes of abdominal segment VIII not reaching paratergites of VIII tergite (Fig. 22, teVIII.); tergal processes of abdominal segment IX completely developed (Fig. 22, teIX.). Gonangulum distinct, well sclerotized (Figs 18, 19, gg.). First valves of ovipositor large and membranous at apex (Fig. 22, v.I.), with setae (not shown in Fig. 22) along inner side. Base of 2nd and 3rd pairs of valves as in Fig. 23. Anterior arch of second valvifer as in Fig. 23, aa. 2nd valves of ovipositor small. 3rd valves of ovipositor (gonoplacs) wide, partly membranous (Fig. 22, v.III.). Basivalvulae well sclerotized, semicircular, not divided into two parts, with reflexed outer margins (Figs 22, 23, bsv.). Vestibular sclerite weakly sclerotized, bilobed (Fig. 22, vs.). Brood sac membranous, with indistinct weakly sclerotized medial plate (Fig. 22, m.pl.).

Scale bars 1 mm: a = 38, b = 39, c = 40, d = 41, e = 42, f = 43, g = 44, h = 45, i = 46, 47, j = 48, k = 49-52, l = 53-55, m = 56, n = 57, o = 58.
female 3.1-3.5; pronotum length: male 3.5-4.0 (3.5), female 4.1-5.1; pronotum width: male 4.6-5.4 (4.7), female 5.5-7.0; tegmen length: male 4.5-5.0 (4.5), female 4.8-6.2; tegmen width: male 3.5-4.0 (3.5), female 4.0-5.0. Measurements in parenthesis are those of lectotype.
Note: In the author’s opinion, the series labelled “ carinulata var. pallida ” do not deserve a separation at the infraspecific level as they differ only in the slightly lighter colouration.
