description: Opiliosina meridionalis Desutter-Grandcolas n. sp.
(Figs 10 D–G, 11, 12, Table 7)
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).
