Diagnosis: G. obscuricolle ( BERNHAUER, 1908)  is the largest species of the group. The vertex of the head is finely punctate, whereas punctures are larger in the other species of the group. The longitudinal micro-striae of the vertex give a characteristic iridescent shine. The smoothly curved aedeagus resembles that of G. schuhi  spec. nov., but the apical lobe is shorter and has fewer sensillae.

Description: Length: 3.2 mm, Colouration: Black; elytra slightly lighter, dark brown; legs and antennae still lighter brown.

Head: 0.40 mm long, 0.60 mm wide; eyes slightly prominent; eyes as long as temples; temples smoothly rounded to the neck in convex curve; sides in front of eyes up to base of antennae parallel; parallel part as long as length of eyes; then, abruptly angulate; narrowed to anterior edge of clypeus in sinuate curve; anterior edge of clypeus 2.5 times as wide as distance between base of antennae; clypeus with moderately dense setiferous punctation; on average, interstices between punctures as wide as or wider than diameter of punctures; on vertex punctation sparer than on clypeus; interstices between punctures at least twice as wide as diameter of punctures; microsculpture extremely dense; consisting of diagonal micro-striae pointing to centre of vertex; on central line of vertex micro-striae more or less longitudinal; thus, surface matt, in central area slightly shiny.

Antennae as long as head, pronotum and half of elytra combined; antennomeres slightly widened anteriad; second antennomere slightly narrower than first; slightly wider than long; third to ninth antennomeres approxi- mately quadrate; tenth antennomere again slightly wider than long.

Pronotum: 0.50 mm long, 0.55 mm wide; widest in anterior third; slightly narrowed to anterior angles in smooth convex curve; anterior angles obtuse, but distinct; anterior edge also slightly convex; posteriad narrowed in concave curve to obtusely rounded posterior angels; posterior edge as wide as neck; setiferous punctation coarse and dense; central area less densely punctate; laterally, interstices between punctures restricted to extreme narrow ridges; punctures partly coriaceous; on disc, punctures smaller; interstices between punctures ranging between as wide as or even wider than diameter of punctures; pair of larger punctures in middle of posterior half in front of posterior edge; margined by transverse moon-shaped carinate structure separated by short longitudinal carinae; indistinct transverse depression in middle shortly behind anterior edge; longitudinal micro-striae microsculpture slightly weaker than on head; surface of large punctures with more or less isodiametric microsculpture; surface matt, but slightly shinier than on head.

Elytra: 0.80 mm long, 0.70 mm wide; widest in posterior third; sides slightly curved in convex curve, but nearly parallel; shoulders obtusely rounded; anterior edge margined; discal carinae distinct; slightly curved; lateral carina absent; suture line deeply impressed; marked by small extremely dense punctures; continuing to posterior edge; between suture line and discal carina two irregular rows of large slightly elongate setiferous punctures; punctation of outer row at discal carina denser than of inner row adjacent to sutural line; outer row partly coriaceous; laterad of discal carina another coriaceous row of setiferous punctures; laterally two more irregular rows of sparser punctures; interstices partly restricted to narrow ridges; longitudinally striate microsculpture dense; on surface of large punctures, microsculpture widely isodiametric; surface matt, but still shinier than on pronotum.

Abdomen with irregular transverse rows of large punctures; on average, width of abdominal punctures as wide as width of punctures of inner rows of elytra.

Aedeagus smoothly curved from basal to apical lobe; apical lobe ending in acute apex; apical lobe laterally with two groups of sensillae; one with numerous sensillae at middle and one with four sensillae at base; paramere thin; reaching middle of apical lobe.
