In contrast to  G. cicatricosa MOTSCHULSKY 1857and  G. rossii spec. nov., the head of  G. laeviceps SHARP, 1887is polished and without micro-striae.   Description: Length: 3.5–3.9 mm. Colouration: black, legs dark yellow, antennae dark brown. Head: 0.45 mmlong, 0.59 mmwide; eyes large and prominent; as long as temples; temples convergent to neck in convex curve; sides in front of eyes parallel; parallel part as long as eyes; then deeply sinuate to narrow clypeus; width of clypeus one third as wide as width of head; with swelling at base of antennae; punctation extremely sparse; only with few scattered small punctures; on average, interstices between punctures four to six times as wide as diameter of punctures; few punctures on vertex larger than others; without microsculpture; surface polished. Antennae nearly as long as head, pronotum and elytra combined, first antennomere thick and rectangular; second only half as long as first and distinctly smaller; third approximately quadrate; following antennomeres approximately as wide as third and longer than wide; penultimate antennomere slightly thicker and again approximately quadrate; last antennomere slightly longer than penultimate; all antennomeres with long setae; setae slightly longer than width of antennomeres; surface of antennomeres matt. Pronotum: 0.71 mmlong, 0.74 mmwide; approximately globular; slightly pear-shaped; sinuate in front of posterior angles, but angles indistinct and rounded; posterior edge not wider than mesonotum; without lateral margin; punctation irregular; punctures extremely large and cori- aceous; three punctures in anterior half on both sides of midline more deeply impressed than laterally; deep furrow along midline more deeply impressed in anterior half than in posterior half; surface of midline and of punctures with deep isodiametric microsculpture, matt; interstices between punctures with weaker microsculpture and more shiny. Elytra: 0.98 mmlong, 0.98 mmwide; sides smoothly curved; widest at middle; shoulders shortly denticulate; disc with two carinae on each side of suture; one in middle between suture and lateral margin; one from shoulders to posterior angles; on inner side of discal carina three indistinct irregular rows of large punctures; on each side of suture indistinct furrow without punctures; on outer side of discal carina and inner side of lateral carina with irregular row of smaller punctures; between these rows wider space without punctures; space between carinae inclusively surface of punctures with deep isodiametric microsculpture; in some parts microsculpture longitudinally reticulate; surface matt. Abdomen at segments III to V with deep transverse groove formed by deep large punctures; posterior half of segments impunctate; surface shiny; segments VI to VIII without transverse row of large and deep punctures and surface totally shiny; only with pair of short yellow setae on both sides of midline. Aedeagus forming nearly rectangular angle between basal and apical lobe; apical lobe long and approximately straight; acute short apex more strongly curved and pointing ventrally; inner edge of apical lobe indistinctly undulate; wider in middle than at base; with numerous sensillae in middle; thin paramere long; reaching apical third of apical lobe; in middle with undulate structure.
