Glaberana acuta sp. nov.

Figs. 1 M , 4 M , 7 M , 25 A–H.

Pygofer in lateral view broad anteriorly and narrowed posteriorly, with caudodorsal process blade-like, slightly curved, tapering to acute apex, margin widely crenulate, with one basal tooth on lateral margin ( Figs. 25 F–H). Subgenital plate, long, narrow, with apical spine preceeded by serrate outer margin in apical 1/5 ( Fig. 25 C ). Style broad at base, apophysis narrowed apically ( Fig. 25 D ). Connective as wide as long with prominent median ledge along entire length ( Fig. 25 E ). Aedeagus dorsally curved in distal ¼, in dorsal view, slightly sinuate near midlength, gonopore subapical on lateral margin ( Figs. 25 A–B).

PARATYPES 1 ♂, INDIA: Meghalaya: Ri-Bhoi, ICAR RC NEH, Umiam , 1031m, 25º41’ N 91º55’ E, 12.vi.2013, Vinayaka, T., sweep net ; 1 ♂, same data except 25.x.2013, C.A. Viraktamath ; 1 ♂, Mizoram: Lunglei , 22xi.1981, C.S. Wesley ( UASB) . Other material: INDIA: Manipur, 2 ♂, Senapati, Sjang, Monjang, 1053m, 24 o 58’ N 94 o 08’ E, 28.ix.2013, Yeshwanth, H.M. (UASB).

Etymology. The species name is descriptive for the pointed caudodorsal process of the pygofer.

Remarks. G. acuta resembles G. khasiensis (Rao) in general habitus and in the structure of male genitalia. It differs from G. khasiensis in having a more acute caudodorsal process of the pygofer. Specimens from Manipur have the pygofer process slightly asymmetrically developed, one being longer and serrated and the other typical.
