description: Xestophrys namtseringa Kumar & Chandra sp. nov.
Holotype: male, India, Arunachal Pradesh, Tawang, Namtsering, 27.53236N, 91.67328E, alt. 1180m., 16.iv.2018, (Collected by H. Kumar).
Description: Male (Figures: 1A–B): Small-sized for the genus, robust. Fastigium of vertex (Figure 2A) elongate angular with obtusely rounded apex; slightly convex above, densely punctate; longer than both eye and scape. Fastigium of vertex without a ventral tubercle at the base of fastigium (Figure 2B). Frons (Figure 2F) convex in profile. Dorsum of pronotum (Figure 2A) densely rugose; anterior margin straight with slight median concavity, posterior margin convex; lateral carinae absent; transverse sulcus distinct throughout, placed in anterior part of pronotum; humeral sinus (Figure 2F) deep. Prosternum bispinose (Figure 2C). Mesosternal lobes (Figure 2C) deeply bifurcated in the middle, apex triangularly rounded and curved upward; metasternal lobes (Figure 2C) triangular. Tegmina surpassing the apex of hind tibia when stretched, narrowing towards obliquely truncated apex (Figure 2H); stridulatory file (Figure 2E) broad, narrow at both ends; mirror of right tegmina (Figure 2D) broad. Hind wing slightly shorter than tegmina. Thoracic auditory spiracle oval, covered by pronotum. Tympanum (Figure 2I) present on fore tibia, laterally closed, opening slit like and directed dorsally. All legs short and thick. All femora dorsally unarmed, genicular lobes unarmed on both sides. Fore coxae spined. Fore femora ventrally armed in apical half by 3 spines on inner margin, 2 spines on outer margin. For tibia unarmed dorsally, ventrally with 6 spines internally and 5 spines externally. Mid femora ventrally unarmed in apical half on inner margin; 3 spines present on outer margin. Mid tibia unarmed dorsally, ventrally with 5 spines on both internal and external margin. Hind femur surpassing the apex of the abdomen. Hind femora ventrally armed by 2 spines apically on inner margin, 8 spines on outer margin. Hind tibiae (Figure 2J) dorsally armed with 11 spines on inner margin, 7 spines on outer margin; ventrally armed with 5 spines on inner margin, 6 spines on outer margin; dorsal spurs one pair, ventral spur two pairs (inner small and outer large). Tenth abdominal tergite (Figure 2K) bifurcated almost from base to form two large triangular lobes. Supra-anal plate (Figure 2M) triangular, longer than wide. Cerci (Figures 2 K–M) robust, conical, apex terminated into large incurved spine; internal tooth well developed, conical, inner margin concave, curved upwards, apex obtuse. Subgenital plate (Figure 2N) long, posterior margin concave; styli long and cylindrical, converged apically, 2.6 times shorter than subgenital plate.
Female: Unknown.
Coloration: General colour yellowish-brown. Labrum and clypeus yellowish. Mandibles black on inner side.
Measurements (mm):
Female: Length of body: 28.69; length of tegmina: 33.69; length of hind wing: 30.2; length of pronotum: 8.7; length of fore femur: 7.1; length of hind femur: 17.3; length of fore tibia: 7.0; length of hind tibia: 15.9.
Discussion: The new species described in this paper is the second species of Xestophrys Redtenbacher, 1891 from India and differs from the previous Indian species, Xestophrys agraensis Farooqi & Usmani, 2018 by not only the characters outlined in the key to species but also by the presence of large spine of male cerci and deeply concave posterior margin of male subgenital plate. The new species is similar with Xestophrys horvathi Bolívar, 1905 but differs from latter by its smaller size, shape of mirror of right tegmen and other characters outlined in the key to species.
Etymology: The geographic name of the new species is based on the locality (Namtsering) of Arunachal Pradesh, India.
Distribution: India: Arunachal Pradesh.
