DIAGNOSIS. An apterous black species similar to G. linearis sp.n. and more so to G. sublineata sp.n. It differs from the latter by the head shorter, HL/HW 1.13 (vs. 1.20–1.24), and barely wider, PW/HW 1.20 (vs. 1.24–1.32), the pronotum broadest a third (vs. two fifths) from apex and about as much (vs. almost half) wider at base than at apex. Aedeagus, including the armature o the finternal sac, is similar, except that the apex of the median lobe is smooth ventrally (vs. longitudinally grooved and finely carinate along middle).

DESCRIPTION. As for G. linearis sp.n. except the following. BL 23.5 mm. Body ( Fig. 21 View Figs 19–21 ) black, vertex with a pair of vague, oblique, reddish spots. Scape dark brown, basal two palpomeres, antennomeres 2–11 and tarsi red (this pale colour may be due to teneral condition of the holotype).

Head elliptic, with genae evenly curved to neck; frontal carina short, traceable up to the level of eye mid-length, limited behind by almost indistinct impression on vertex.

Pronotum with sides distinctly diverging to base in basal fifth; basal angles subacute and blunt. Base truncate, apex sinuate and straight at middle. Disc moderately convex, rather finely and confluently punctate. Basolateral foveae and sublateral lines very shallow, separated at middle.

Elytral apices obliquely truncate and angulate combined, nearly straight, rounded at sutural angles, thus forming minute re-entrant angle; outer angles less obtuse and narrowly rounded. Pubescence similar, yet slightly sparser and arranged in 1–2 (mostly single) rows on each side of ridge 2 in apical half and of ridge 4 before apex. Interval 3 with four discal setae.

Aedeagus poorly sclerotized due to teneral condition of the specimen ( Figs 62 View Figs 44–65 , 108–110 View Figs 108–113 ): left paramere parallel-sided in basal three fifths, triangular toward a moderately rounded apex. Internal sac with at least right laterobasal bulb, twelve (large ten and small two) dorsomedial and seven left lateral sclerites; of these latter, basalmost one being large and curved (perhaps it is situated at apex of left laterobasal bulb, which is vestigial or ill-defined due to imperfect preparation of the teneral specimen).

DISTRIBUTION. Only known from the type locality.

NAME. Refers to the fairly short head.

HABITATS AND HABITS. The only specimen was hand collected from under log on the ground in a monsoon forests.
