Latidrymus zetteli View in CoL sp. nov.

( Figs 4 View Figs 2–7 , 11 View Figs 8–12 )

Type locality. India, Meghalaya State, W Garo Hills, Balphakram National Park, 25°11’N 90°51’E.

Type material. HOLOTYPE: J, ‘NE INDIA: Meghalaya State / W Garo Hills, Balphakram NP / 22.–27. V. 1996, 250– 550 m / GPS N 25°11’ E 90°51’ (WGSB4) / leg. E. Jendek & O. Sausa’ ( NHMW).

Description. Colour. Head fuscous, anteclypeus, mandibular plates, labium excluding tip, scape and pedicel stramineous, basiflagellum and basal part of distiflagellum reddish brown, apical part dark brown; pronotum stramineous with slightly darker punctures, anterior pronotal disk dark brown except margins and collar ( Fig. 4 View Figs 2–7 ); scutellum brown except stramineous midline; clavus whitish except a small basal spot; anterior half of corium and some obscure spots on apical half of corium whitish, posterior half mostly brown, endocorium posteriorly between inner rows of punctures black (extending laterally in anterior part); membrane translucent with some small brown spot on disk and three larger spots on hind margin; sternum fuscous with brown margins and stramineous metepisternum; legs stramineous, preapical rings of femora obscure; abdomen brown, posterior half of connexivum dorsally and ventrally pale. Structure. Similar to L. elevatus sp. nov. but elevations close to transverse impression on anterior pronotal lobe weaker. Labium reaching apex of mid coxae, segment I reaching base of head. Pronotal lateral margin posteriorly continued to basal margin without a strong incision. Posterior half of pronotum more densely punctate, punctures partly touching each other. Median carina of pronotum indistinct. Scutellum with nearly T-shaped carina. Mesosternum with extremely fine punctures, medially with strong punctures, submedially transversely wrinkled. Paramere similar to that of L. puskasi sp. nov, albeit with a more slender sensory lobe ( Fig. 11 View Figs 8–12 ).

Measurements (in mm). Holotype. Total body length 2.84; head: length 0.42, width 0.68, interocular space 0.42; pronotum: length 0.86, width at base 1.22; scutellum: length 0.52, width 0.56; claval commissure length 0.20; length of antennal segments: scape 0.22, pedicel 0.36, basiflagellum 0.36, distiflagellum 0.48; length of labial segments: I 0.28, II 0.26, III 0.21, IV 0.16.

Differential diagnosis. In some characters Latidrymus zetteli sp. nov. is transitional between L. puskasi sp. nov. and L. elevatus sp. nov., but differs from both species in the small body and the coloration of the antenna, corium and membrane. It is the only species in the genus in which the dark spot of the endocorium extends beyond the two inner rows of punctures. The pale midline of scutellum is present only in L. elevatus sp. nov. and L. zetteli sp. nov., but only L. elevatus has a continuous dark margin on the membrane and the coloration of the anterior lobe of the pronotum of L. elevatus sp. nov. is much paler than the head (it is similarly dark brown to the head in L. zetteli sp. nov.).

Etymology. The new species is named in honour of Herbert Zettel, prominent specialist on Oriental Gerromorpha and Nepomorpha, curator of Hemiptera at the NHMW, who made my studies in NHMW possible and helped me with loans of specimens during the last two decades. Collection circumstances. The habitat at the type locality, Balphakram National Park, is illustrated on Fig. 14 View Figs .
