Type locality. India, Karnataka, route de Kadari, 800– 900 m.

Holotype: 1 male, India, Karnataka, route de Kadari, 800–900 m, forêt dégradée, cavités dans paroi de terre (MNHN-ENSIF2945). Allotype: 1 female, same data as the holotype (MNHN-2947). Paratypes. Same data as holotype, 2 males (MNHN-ENSIF2946, IISc) and 8 females (MNHN-ENSIF 2948-2951, ENSIF 2961-2962, IISc).

Other material examined. Same data as the holotype, 2 juveniles ( MNHN).

Diagnosis. In addition to the characters of the genus: Colouration. Face yellowish brown, bordered by a dark band extending between each eye and the mandibula, as on Fig. 10 F, and including a dark, thin triangular spot close to epistemal suture bordered by yellow, a brown rounded spot and a transverse fleck under each eye, and a dark round spot circled with black under median ocellus; cheeks with a light-yellow line under the eye lower angle; palpi yellow and brown; pronotum brown to dark brown with a transverse yellow band, the dorsal margins yellow ( Fig. 10 E), the lateral lobes entirely dark; legs annulated ( Fig. 10 D); tergites brown, mottled with yellowish and dark brown ( Fig. 10 E); cerci brown with a basal yellowish ring. Male. Apterous. Metanotum not glandular, but tergite 1 elongate, covering tergite 2, and with a thick distal margin ( Fig. 10 E). Male genitalia ( Fig. 12 ): median lobe of pseudepiphallus rounded, only slightly longer than the lateral parts ( Fig. 12 A); lateral lobes sclerotized on inner and outer sides; pseudepiphallic parameres hook like ( Fig. 12 B, C); ectophallic fold deeply subdivided apically ( Fig. 12 C), slightly asymmetrical laterally, and with sclerotized lateral margins; ectophallic arc lacking ( Fig. 12 A); endophallic sclerite having the shape of a wide U, with a crest-like apodeme ( Fig. 12 A, B). Female. Subgenital plate distal margin deeply sinuate ( Fig. 11 G). Ovipositor very small, about half femur length. Female genitalia. As on Fig. 11 H–J.

Description. In addition to the characters of the genus: Legs. TIII inner and outer apical spurs as on ( Fig. 11 C, D); inner serrulation: no spine between spurs 1 and 2, zero to four spines between spurs 2 and 3 (mean 0.6, n= 5 in males, mean 1.9, n= 8 in females), zero to five spines between spurs 3 and 4 (mean 1.8, n= 5 in males, mean 2.6, n= 8 in females), zero to six spines above spurs (mean 1.8, n= 5 in males, mean 2.8 n = 8 in females); outer serrulation: one to four spines between spurs 1 and 2 (mean 3.0, n= 5 in males, mean 3.0, n= 8 in females), four to eight spines between spurs 2 and 3 (mean 4.0, n= 5 in males, mean 5.3, n= 8 in females), four to seven spines between spurs 3 and 4 (mean 5.6, n= 5 in males, mean 6.0, n= 8 in females), three to seven spines above spurs (mean 5.6, n= 5 in males, mean 5.6, n= 8 in females). Basitarsomeres III with two rows of small spines dorsally: zero to one inner spine (mean 0.2, n= 9 in males, mean 0.1, n= 8 in females), and two to six outer spines (mean 2.8, n= 5 in males, mean 4.5, n= 8 in females), in addition to distal spines. Terminalia. Cerci long, longer than body length.

Colouration. Body dark brown, legs yellow annulated with brown. Face, buccal parts and cheeks yellow, with dark brown spots ( Fig. 10 F): a black acute triangular close to epistemal suture, a rounded dark spot under each eye, lower margin of each eye brown, connected to a wide brown band extended down to mandibula basal third; a dark round spot circled with black under median ocelli. Palpi yellow and brown; joint 5 yellow, brown in distal third. Antennae brown. Scapes yellow and brown. Pronotum brown to dark brown, the pyriform inscriptions dark ochre, a transverse spot in anterior half light ochre; lateral lobes entirely and distinctly dark. Legs yellow, annulated and marked with brown: FI, FII with three brown rings and a small basal brown spot; TI, TII with three brown rings, the basal one reaching almost tibia mid length; FIII with three brown rings in apical half, and additional brown spots on basal inner and outer sides ( Fig. 10 G). Body brown; distal margin of meso-, metanotum and tergite 1 yellow ( Fig. 10 E); a rounded yellow spot more or less distinct on each side. Cerci brown with a basal yellowish ring.

Male. Apterous. Metanotum and tergites not glandular. Supra anal plate lateral lobes slightly elongate ( Fig. 11 E); brown, the base yellow. Subgenital plate long and relatively flat ( Fig. 11 F).

Male genitalia. Median lobe of pseudepiphallus rounded, only slightly longer than the lateral parts, and sclerotized on its margins only ( Fig. 12 ). Lateral lobes higher than wide or long, sclerotized on inner and outer sides. Pseudepiphallic parameres comprising a very thin apical, semi-circular hook and a more basal, not sclerotized plate ( Fig. 12 B). Ectophallic fold very close to pseudepiphallic sclerite dorsally, deeply subdivided apically ( Fig. 12 B, C); left lateral margin larger than the right one; membranous, except for sclerotized lateral margins. Epi-ectophallic invagination narrow dorsally (ectophallic arc lacking), but deeper laterally with sclerotized margins ( Fig. 12 A); ectophallic apodemes short and divergent, higher than wide ( Fig. 12 A, D). Endophallic sclerite having the shape of a wide, rounded U ( Fig. 12 A, B); endophallic apodeme short, crest-like ( Fig. 12 A, B).

Female. Apterous. Subgenital plate emarginate distally ( Fig. 11 G). Ovipositor very short, about two thirds of TIII length.

Female genitalia. Distal margin of copulatory papilla emarginate; sclerotization apical only ( Fig. 11 H–J).
