Indoapterolampra rugosiuscula Anisyutkin View in CoL , sp. nov.

( Figs. 1A–C View FIGURE 1. A, D, F , 2 View FIGURE 2 A–K, 3 View FIGURE 3 A–J)

Material. Holotype — male, SOUTH INDIA, state Tamil Nadu, Coimbatore, 1400 ft., November 1959, coll. P.S. Nathan ( MMUM); paratype — male, same data as the holotype ( ZIN) .

Description. Male (the holotype). General color black, with yellowish elements ( Figs. 1A–C View FIGURE 1. A, D, F , 2 View FIGURE 2 B); central part of facial part of head ( Fig. 2 View FIGURE 2 A), thoracic and abdominal tergites black; eyes and antennae brownish; vertex, areas at ocellar spots, lateral parts of head and mouthparts yellowish; pronotum and, in less degree, mesonotum bordered with yellow along anterior and lateral sides, metanotum and abdominal tergites bordered with yellow along lateral sides; pro-, meso- and metanotum with yellow spots on caudal margins; legs contrastingly colored ( Fig. 1C View FIGURE 1. A, D, F ), brown, partly yellowish; abdominal sternites reddish brown; cerci and styli yellowish. Surfaces lustrous; antennae with lustrous proximal 12–13 segments, the rest of segments dull; thoracic and abdominal tergites strongly punctuated, somewhat rugose, with longitudinal inflations ( Figs. 1B View FIGURE 1. A, D, F , 2 View FIGURE 2 B); facial part of head punctuated, with wrinkles above mouthparts ( Figs. 1A, C View FIGURE 1. A, D, F , 2 View FIGURE 2 A). Head distinctly rounded at vertex, slightly longer than wide ( Figs. 1A, C View FIGURE 1. A, D, F , 2 View FIGURE 2 A); ocellar spots distinct; distance between eyes about as long as eye length; distance between antennal sockets about 2.2 times of the scape length (1 mm); approximate length ratio of 3rd–5th segments of maxillary palps 1: 1:. 1.1. Thoracal tergites convex; thoracic and abdominal tergites laterally margined ( Figs. 1B View FIGURE 1. A, D, F , 2 View FIGURE 2 B). Pronotum campaniform, anterior and lateral margins semicircular; meso- and metanotum transverse; pro- and metanotum with posterior margin weakly projected caudally, mesonotum with posterior margin nearly straight; posterolateral margins distinctly attenuate caudally ( Figs. 1B View FIGURE 1. A, D, F , 2 View FIGURE 2 B). Anterior margin of fore femur armed as in the type B, with 5 spines, including 2 apical ones. Fore tibiae thickened distally ( Fig. 2 View FIGURE 2 C), all tibiae distinctly dorsoventrally flattened. Claws symmetrical, simple; arolium vestigial ( Fig. 2 View FIGURE 2 F). Anal plate (tergite X) with caudal margin rounded, median incision indistinct ( Fig. 2 View FIGURE 2 G); cerci short, dorsoventrally flattened, with indistinct segmentation, densely covered with bristles from below ( Fig. 2 View FIGURE 2 H, I).

Variations. The facial part of head in the paratype more sculptured, rugose. Approximate length ratio of 3rd–5th segments of maxillary palps 1: 1: 1.3. Anterior margin of fore femur with 5 spines, including 1 apical one. Anal plate with caudal margin very weakly incised. Sclerite R3 of male genitalia with cranial apex bent upward in less degree ( Fig. 3 View FIGURE 3 F); R5 comparatively larger than in holotype, irregularly sclerotized ( Fig. 3 View FIGURE 3 E).

Female unknown.

Measurements (mm). Head length: 4.5 (4.5), width 4.3 (4.3), pronotum length 5.7–6.3(5.7), width 8.8–9.3(8.8), mesonotum length 2.7–3(2.7), width 9.4–10(9.4), metanotum length 3.0(3.0), width 9.8–10.1(9.8). Measurements in parenthesis are those of holotype.

Comparison. As given for the genus.

The new species is somewhat similar to Placoblatta rugosa Bey-Bienko, 1969 , but readily differs from it in the absence of tegmina and the structure of the apical part of sclerite L2D ( Anisyutkin 1999).
