Type material examined

MALAYSIA: Syntypes of Gergithus rugulosus (examined on photographs, Fig. 8 ): 1 ♂ [Malacca, Perak] [ rugulosus M det. Melichar] [Typus] [ NHRS-GULI 000009432 ] ( NHRS) ; 1 ♀ [ Malacca, Perak] [ rugulosus M det. Melichar] [Paratypus] [ NHRS-GULI 0 0 0 0 29484 ] ( NHRS) ; 1 ♀ [ Malacca, Perak] [ rugulosus M det. Melichar] [Syn-typus] [transcriptio Gergithus rugulosus sp. n. ♀, L. Melichar 1906] [Invent. č 3377 / Ent, Mor. Museum, Brno] ( MMBC) .

Remarks

This species was described based on 3 syntype specimens ( Fig. 8 ) from southern Malaysia. The genitalia of the male syntype were not illustrated to date.

The species was later mentioned from China: from Fujian by Jacobi (1944), from Guangxi, Sichuan and Yunnan by Che et al. (2003), and from Guizhou by Chen et al. (2014).

Male genitalia attributed to the species were illustrated by Chen et al. (2014) based on a male specimen from Guizhou. It seems worth mentioning that the specimens from Guizhou are from the same collecting event as female specimens attributed by Chen et al. (2014) to another species, G. carinatifrons , and illustrated as such (see comments under G. carinatifrons ). We consider that the specimens illustrated as G. rugulosus and G. carinatifrons by Chen et al. (2014) are actually conspecific and should represent a new species.

Subsequently, the presence of G. rugulosus in China remains highly questionable. This issue needs to be solved by the study of the genitalia of the male syntype of G. rugulosus .
