Redescription. Body moderately narrow ( Fig. 64 ), length ca. 2.00 mm. Head, mouthparts, antennomeres 4–11 and abdomen dark brown, pronotum reddish-brown, elytra yellow-brown with dark brown lateroapical and posterolateral portions; antennomeres 1–3 and legs yellow. Microsculpture of forebody indistinct, reticulate. Head 1.2 times as wide as long, with rows of fine, indistinct punctures in laterobasal portions behind eyes; middle and basal portion without punctures. Basal antennomere twice as long as wide, antennomere 2 distinctly shorter and narrower, twice as long as wide; 3 narrower than 2, twice as long as wide, 4 distinctly transverse, twice as wide as long, 5–6 longer and slightly wider than 4, 7–10 slightly shorter than 6, apical antennomere about twice as long as 10. Pronotum 1.6 times as wide as long, 1.2 times as wide as head, with two longitudinal rows of very fine punctures (0.01 mm diam.) and two moderately large (0.03 mm diam.) mediobasal punctures; basal portion of pronotum without punctation. Elytra 1.4 times as wide as long, 1.3 times as wide as pronotum, surface covered with sparse and fine (0.01 mm diam.) punctures. Abdomen moderately narrow, gradually narrowed apically.

Male. Basal portion of aedeagus very wide; dorsal projection very narrow and long, with folded short flagellum; ventral plate S-shaped, distinctly shorter and about as wide as dorsal projection, with acute apex ( Fig. 65 ). Abdominal tergite VII with rounded tubercle in middle. Apical margin of abdominal tergite VIII with two widely separated, strong and moderately wide, slightly curved inwards latero-apical projections ( Fig. 66 ). Apical margin of abdominal sternite VIII with wide, small, rounded notch ( Fig. 67 ).

Female. Abdominal tergite VII without modification. Apical margin of abdominal tergite VIII slightly concave ( Fig. 68 ). Apical margin of abdominal sternite VIII rounded ( Fig. 69 ).

Comparative notes. Based on the coloration of the body, shapes of the antennomeres, some features of the punctation and microsculpture, and the general shape of the dorsal projection of the median lobe, G. permutaria is similar to Taiwanese G. taiwanova Pace 2007 , described from Kaohsiung Hsien ( Pace 2007), from which it can be distinguished by the smaller body and different shape of the ventral plate of the aedeagus.

Distribution. India (Kashmir).

Remarks. Schubert (1906) described G. permutaria var. puncticolle based on the single specimen, which distinguished from G. permutaria by insignificant details of the coloration and punctation of the pronotum. Bernhauer & Scheerpeltz (1926) synonymized it with the latter taxon.
