D e s c r i p t i o n: Species of moderately large size, 2.7-3.7 mm (abdomen fully extended). Coloration: head dark brown to blackish; pronotum brown to blackish brown; elytra yellowish brown to dark brown; abdomen blackish, often with the apex and segments III-V paler; legs testaceous; antennae brown to dark brown.

Facies as in Fig. 1 View Figs 1-12 . Head and pronotum with shallow microreticulation ( Fig. 2 View Figs 1-12 ). Eyes moderately small ( Fig. 3 View Figs 1-12 ), weakly protruding from lateral outline of head, approximately half the length of postocular region in dorsal view.

Pronotum without sexual dimorphism, in both sexes approximately 1.15 times as wide as head and approximately as long as wide or indistinctly oblong ( Fig. 2 View Figs 1-12 ). Elytra with rather weakly pronounced sexual dimorphism, less than 0.6 times as long as pronotum.

Abdomen rather shining; puncturation relatively dense and coarse on anterior tergites, sparse and fine on posterior tergites; microsculpture composed of transverse striae and transverse meshes, more distinct on tergites VI and VII than on tergites III-V; posterior margin of tergite VII without or with very narrow rudiment of a palisade fringe.

(large): elytra with somewhat granulose puncturation especially near posterior angles, a short distance anterior to posterior angles with short fold ( Figs 2, 4 View Figs 1-12 ); abdominal tergites III-V unmodified; process of tergite VII long, acute, and erect ( Figs 5-6 View Figs 1-12 ); sternite VIII as in Fig. 7 View Figs 1-12 ; median lobe of aedeagus with thin cristal process ( Figs 8-9 View Figs 1-12 ); apical lobe of paramere shaped as in other species of the subgenus.

: elytra with unmodified fine puncturation, near posterior angles at most with indistinct indication of fold; sternite VIII as in Fig. 10 View Figs 1-12 ; spermatheca as in Figs 11-12. View Figs 1-12

E t y m o l o g y: The name (Lat., adj.) is derived from the name of the mountain where the species is probably endemic.

I n t r a s p e c i f i c v a r i a t i o n: The male secondary sexual characters are pronounced only in seven of the twelve male type specimens. In the other males, the elytral puncturation is only indistinctly granulose, the elytral folds are weakly elevated, the process of tergite VII is completely absent or nearly so, and the cristal process of the median lobe of the aedeagus is thinner ( Fig. 9 View Figs 1-12 ).


C o m p a r a t i v e n o t e s: See comparative notes in section on G. atromonis sp.n. and supplementary key in the section on G. renneri   sp.n.

D i s t r i b u t i o n a n d b i o n o m i c s: As can be inferred from the restricted distributions of other species of the subgenus, G. nifica   is probably endemic to the Nif Da÷ı to the east of Izmir ( Map 3 View Map 3 ). The types were sifted from grass roots and litter below scattered old pine trees and from litter in rocky crevices at altitudes of 920-1400 m.
