Redescription. Body red-brown to dark-brown; body length 1.50–2.30 mm. Habitus as in Figs. 41View FIGURES 39–46, 49View FIGURES 47–50. Head and antennomeres 4-11 dark-brown; pronotum slightly paler than head, red-brown; disc of elytra golden-brown, with posterolateral angles dark-brown; abdomen red-brown except of segments V–VI dark-brown; antennomeres 1-3 yellow-brown; mouthparts brown; legs yellow-brown to red-brown. Body with distinct reticulate microsculpture. Head 1,4 times as wide as long, with distinct reticulate microsculpture and more than 8 rather large (about 0,0 1 mm diam.), distinct punctures forming rows behind eyes; median portion of head impunctate. Antennomeres 1–3 elongate, antennomere 4 subquadrate to slightly elongate, antennomeres 5–10 subequal in length, subquadrate to slightly transverse; apical antennomere conical, 1.4 times as long as wide. Pronotum somewhat flat, 1.4 times as wide as long and 1.3 times as wide as head; microsculpture as that on head, with two median rows consisting of small, irregular punctures and with similar punctures on sides of each row near margins of pronotum; median portion impunctate; basal portion with slightly defined punctation. Elytra 1.6 times as wide as long and 1.4 times as wide as pronotum, with distinct reticulate microsculpture; each elytron with indistinct, sparse, small punctation and few weakly defined tubercles on posterior angles. Abdomen wedge-shaped, with microsculpture as that on head and pronotum.

Male. Abdominal tergite VII with two elliptic median tubercles obliquely turned towards each other, and with two pairs of longer lateral elevations from each of median tubercle. Apical margin of abdominal tergite VIII with four teeth: two widely separated, moderately wide and markedly elongate, slightly curved toward rounded apices and two very short and narrow medial teeth ( Figs. 43–44View FIGURES 39–46, 48View FIGURES 47–50). Ventral plate of aedeagus narrowly elongate, arcshaped (if see laterally), ventral margin even in outline (without bulging on the middle part and not angled bent near the base), acute apically (lower edge of the ventral plate even); apical projection short ( Figs. 42View FIGURES 39–46, 47View FIGURES 47–50); dorsal projection of internal sac equal to ventral plate, inclined to it, twisted into narrow tube, rather regularly elongate in shape.

Female. Surface of abdominal tergite VII somewhat flat, with a number of small round tubercles on apical margin; tergite VIII widely trapezoid, truncate apically ( Fig. 45View FIGURES 39–46); sternite VIII rounded apically, blunt-pointed ( Fig. 46View FIGURES 39–46).

Comparative notes. Based on the punctation, microsculpture, and coloration of the body, G. hochhuthi  is similar to G. congrua  , which is distributed in Europe, the European part of Russia, Caucasus, Siberia and the Russian Far East ( Schülke & Smetana 2015). It can be distinguished by the shape of middle teeth on the apical margin of male abdominal tergite VIII (these teeth are significantly longer in G. congrua  ), and the morphology of the aedeagus (lower margin of the ventral process of G. congrua  slightly angled; dorsal projection of the internal sac of the aedeagus narrowly elongate and sinuate).

Remarks. Bernhauer (1908) described G. hochhuthi  ( Figs. 49–50View FIGURES 47–50) based on the single female from Margilan, south-eastern part of Fergana Valley ( Uzbekistan). It is noteworthy that the author compared this species with G. fasciata  , which I interpret as G. congrua  , because these species ( G. fasciata  and G. congrua  ), as well as G. laevipennis Kraatz 1856  were confused with each other in nineteenth and twentieth centuries ( Bruge 2005, Enushchenko & Semenov 2016).

Among large series of G. hochhuthi  from Kazakhstan and Kyrgyzstan, I found several specimens that are slightly different from other specimens in the shape of aedeagus and the male abdominal tergite VIII ( Figs. 47–48View FIGURES 47–50). Lateral teeth on apical margin of its abdominal tergite VIII rather long, thin and weak, slightly acute and curved inwards (medial teeth of abdominal tergite VIII of G. hochhuthi  often shorter, rather stout and obtuse); median teeth short, blunt and weak as that in G. hochhuthi  . Ventral plate of aedeagus narrowly elongate, with distinct convex ventral margin, acute apically; apical projection rather long and curved, blunt; dorsal projection of the internal sac equal to the ventral plate, inclined to it, twisted into a rather wide tube, slightly broadened apically, irregularly elongate in the shape. Based on the characters of the body, it corresponds with other studied specimens of G. hochhuthi  . I suppose, that is an example of aberrant variability of this species.
