Telogmometopius bifasciatus sp. nov.

( Figures 32 , 83–85 )

Description

Relatively small species, length: „ 5.2 mm.

General colour brown; ocelli suffused with red; antennal scape, pedicel, and expanded flagellar base, upper margin of frons, and mesosterna, fuscous; fore wings pale, with two transverse fuscous fasciae: one before middle and the other subapical.

Postclypeus strongly compressed laterally and median keel on postclypeus very fine and sharp.

Male genitalia with pygofer ( Figure 83 ) in lateral view with posterior margin rounded; subgenital plates ( Figure 84 ) with basal expanded region narrow and slender, nearly triangular in ventral view, base broad, tapered from base to apex; apical spine-like process relatively stout, tapered from base to apex, posterodorsally directed in lateral view; genital styles not examined (missing). Aedeagal shaft ( Figure 85 ) very long and slender with an elongate, anteriorly directed filamentous process arising from dorsal margin of an expanded apex, in lateral view.

Material examined

Holotype: „, [ Malaysia]: northern Borneo [Sabah], Alcock , Lallemand Coll., B. M. 1955– 832 ( BMNH).

Non-type material examined. One female specimen from Sabah, Mt Kinabalu (BMNH) may belong to this species.

Distribution

Sabah.

Remarks

This species is similar to rangoonensis but has the subgenital plate tapering more gradually and the aedeagal shaft more elongate. The styles and one subgenital plate of the unique type are missing. With respect to the aedeagus its process is now detached and lying within the pygofer (drawn re-associated in Figure 85 ). In consequence it is not clear if the lightly sclerotized apical part (basad of the process), as figured, is complete. Despite these deficiencies, sufficient critical parts of the male genitalia remain to enable adequate identification.
