Revision of Cataulax Spinola, with Architas Distant as a new synonymy (Heteroptera: Pentatomidae: Discocephalini)

Abstract

Five species are here recognized for the genus Cataulax Spinola, 1837: Cataulax eximius (Stål, 1860), Cataulax froeschneri, n. sp., Cataulax pudens (Distant 1889), Cataulax radians, n. sp. and Cataulax subtiliterconspersus, n. sp. Cataulax pudens is transferred from Architas Distant, 1889, here considered a junior synonym of Cataulax. Cataulax annulicornis Walker, 1868, Cataulax punctipes Walker, 1868 and Cataulax subvittatus Walker, 1868 are considered incertae sedis.

An update of the distribution of the stink bugs (Hemiptera: Pentatomidae) from Argentina

“…The genus Cataulax has the following combination of diagnostic characters: body obovate; rostrum with a minute intercalary segment between basal two segments; mesosternum tumid, in a median, elevated, broad calloused ridge; metasternum hexagonal, elevated into a thicket plate, with the apical margin emarginate; third abdominal segment with a median, flat tubercle which fits in apical emargination of the metasternum; and median abdominal furrow broad and shallow, reaching sixth sternite. Cataulax froeschneri can be distinguished from other species of the genus by the structure of the parameres, the pattern of the membrane venation, the presence of bands of fuscous punctures on head and pronotum and arranged in four darkest patches along basal portion of scutellum (Grazia et al, 2000).
