The phallobase of both taxa are characterized by the presence of a ventral lamellous process in the apical third and by a semicircular sharply pointed apophysis at the right side of the apical phallobasis. G. shaanxiana sp. n. may be differentiated from G. hubeiana by the shape of parameres: the left paramere is simple, the right paramere is a little longer and more robust.

Metatibia moderately broad and short, at middle convexly widened, ratio width / length: 1 / 3.5, dorsally sharply edged, with two groups of spines, the basal group at one third, apical one at two third of metatibial length, basally with a few single spines in punctures; lateral face longitudinally convex, with moderately dense and fine punctures, some of them longitudinally impressed, sparsely and finely setose; ventral edge serrated, with three strong and long spines, of which the distal one is more distant; medial face not punctate and smooth, apex interiorly near tarsal articulation sharply truncate. Tarsomeres dorsally glaborus and finely punctate, ventrally with sparse, short setae; metatarsomeres dorsally with strong longitudinal impressions, ventrally with a strongly serrated ridge, laterally with a strong longitudinal carina, first metatarsomere as long as the following two tarsomeres combined and more than twice as long as the upper tibial spur. Protibia short, bidentate, protarsal claws symmetrical.

B04187B5500DFF853C683F78FBE0F9B4.taxon	diagnosis	Diagnosis. G. stictica sp. n. has an external morphology which is very similar to that of G. namthana Ahrens and G. contaminata sp. n. It may be differentiated from both taxa by its longer antennal club in male as well as by the morphology of aedeagus: the phallobase has apically at the left side a long and broad apophysis, wich is apically in cross section s­shaped, the parameres are slender, very long (little longer than the phallobase) and medially moderately curved.	en	Ahrens, Dirk, Pacholátko, Petr (2003): New data on the distribution of species of Gastroserica Brenske, 1897, with descriptions of five new taxa from China and Laos (Coleoptera: Scarabaeidae: Sericini).
