A—Female in lateral aspect; B—Fore wings in focus; C—Mesosoma in focus; D—Head in frontal aspect; E—Label data. Mesosoma. Length of mesosoma 1.8 × its height; pronotum crenulate, dorsally and ventrally rugose ( Fig. 2D ); mesopleuron ( Fig. 2C ) anterior one third strongly crenulated and remaining part smooth and glabrous in posterior two third; mesoscutum smooth; notauli narrow, crenulate; scutellar sulcus wide, with one carina and few weak rugae; scutellum nearly smooth with few shallow punctures; propodeum irregularly reticulate-rugose, with median carina basally and areola obsolescent ( Fig. 2F ). Fore wing ( Fig. 2G ): 1-SR+M slightly curved, SR1 straight. Veins (relative length) r:3-SR: 2-SR: SR1 = 27:29:29.5:106; r-m = 13.2; 1-CU1:2-CU1 = 12:51.5. Vein m-cu far antefurcal and curved; second submarginal cell subquadrate. Hind wing vein 2-SC+R longer than wide (11.2); cu-a: 1-M: M+CU = 19.5: 60: 58; r/3-SR = 0.9. Legs. Hind coxa almost smooth; length of femur, tibia, and basitarsus of hind leg 5.0, 10.3 and 9.2 × their width, respectively; length of hind tarsus 1.1 × as long as hind tibia; length of longer hind tibial spurs 0.3 × as long as hind basitarsus. Metasoma. Length of first tergite 1.1 × its apical width, its surface longitudinally rugose ( Fig. 2H ), dorsal carina united at basal one third, connected to a distinct median carina; dorsope large; second tergite distinctly longitudinally rugose; third tergite weakly longitudinally rugose with transverse short rugae; length of second tergite 1.2 × as long as third tergite and third tergite narrowed posteriorly; fourth and its following tergites smooth and largely retracted ( Fig. 2E ); length of ovipositor sheath 0.5 × as long as fore wing and slightly shorter than metasoma. Etymology. Named after the Karbi tribe, which is the main tribe in the Karbi Anglong and West Karbi Anglong districts of Assam . Comments. The Indian species does not fit in the key to the Chinese species by Chen & He (1997) . The new species shows similarity with C. cephalus , C. hubeiensis , C. nigricans and C. xinjiangensis in having vein r of fore wing 0.9 × as long as vein 3-SR. However, it can be clearly differentiated using the following characters: length of ovipositor sheath 0.7 × length of metasoma in C. xinjiangensis ( vs nearly as long in C. karbi ); length of third, fourth and penultimate segments 4.2, 3.2 and 2.4 × their width in C. cephalus ; 3.8, 3.0 and 2.0 × in C. hubeiensis ; and 4.0, 3.0, 2.5 in C. nigricans , respectively ( vs 2.2, 2.5, 2.6 × in C. karbi ). Clinocentrus foveatus is similar to the new species because of the robust basal antennal segments and the similar shape of the metasoma. Comparing with the images of C. foveatus ( Fig. 3 ; coll.mfn-berlin.de/u/49d382) kindly supplied by Stefanie Krause (Museum für Naturkunde, Berlin) the following differences in fore wing venation and propodeal sculpture are observed. The areolate portion of the propodeum is minimally developed to almost smooth at basal one third with presence of median carina in C. foveatus (vs propodeum completely irregularly reticulate-rugose in C. karbi ); veins 2-M and 3-SR of fore wing straight in C. foveatus ( vs clearly convex or curved in C. karbi ); mesopleuron with oblique row of crenulae in C. foveatus ( vs smooth in middle and apical region, without any oblique row of crenulae in C. karbi ). Clinicentrus compositus is easy to separate from the new species because of the elongated first metasomal tergite (about 2.0 × longer than its apical width in C. compositus ( vs 1.1 × in C. karbi ) and the inter-ocellar distance slightly greater than diameter of an ocellus ( vs slightly smaller than diameter of one ocellus in C. karbi ).
