Telogmometopius bicarinatus sp. nov.

( Figures 31 , 69–73 )

Description

Small and slender species, length: „ 5.4 mm, ♀ 5.3 mm.

Vertex and pronotum pale ochraceous; ocelli suffused with reddish; callous areas on posterior area of vertex and anterior area of pronotum brown; head ventrally brown, median keel of postclypeus (including its lower expanded area), anteclypeus and rostrum ochraceous; antennae with pedicle and expanded flagellar base fuscous; thorax ventrally and legs ochraceous with brown suffusion; fore wings pale stramineous with an indistinct, narrow, obliquely transverse, pale white fascia, before middle; area behind transverse pale white fascia and apical outer margin dark brown; abdomen brown or dark brown with posterior margins ochraceous.

Postclypeus with lower two-thirds of median keel distinctly dilated laterally resulting in a diamond-shaped, flattened, median region, laterally carinate.

Male genitalia with subgenital plates ( Figures 69–71 ) with expanded basal region small and apical spine-like process very long and straight, about three times length of expanded basal region. Style as in Figures 72 and 73 . Aedeagal shaft ( Figure 70 ) very elongate with distal third tapered into an apical, sinuate, filamentous process, apex curved posterodorsally.

Material examined

Holotype: „, India: Meghalay , Cherrapunji, 1299 m, 5 November 1981 (C. A. Viraktamath) ( BMNH) . Paratype: India: 1♀, same data as holotype ( UASB) .

Distribution

Northeastern India.

Remarks

This species can be distinguished externally by its postclypeus with the lower two-thirds of the median keel distinctly dilated laterally, resulting in a diamond-shaped, slightly sulcate, median area bordered laterally with a carina. It can be distinguished in the male genitalia by its subgenital plates having a small expanded basal region and a very elongate apical spinelike process.
