( Fig. 1 )

Pseudonortonia abbreviaticornis Giordani Soika 1941: 246 , fig. 21 (5), ♂ —“ China meridionale: East Kwantung , Tsin-Leng ” (lectotype MSNVE).

Pseudonortonia crassipunctata Gusenleitner 2001: 655 , 657, ♂ —“ Laos: Louangnamtha Prov., Namtha—Muang Sing , 21°09’N 10119’E, 900-1200m ” (OLML). Syn. nov.

Diagnosis. The female of this species can be distinguished from the other Oriental species of Pseudonortonia by the following combination of characters: clypeus sparsely and finely punctate; occipital carina shallow and straight on gena; pronotal carina almost entirely absent dorsally; propodeal shelf as long as metanotum and deeply furrowed, about at same level as scutellum; T1 1.0–1.1× as long as apically wide and densely punctate, interspaces forming reticulation; T2 with punctures becoming abruptly coarser and denser preapically, interspaces mostly smooth and shiny, short smooth apical part not preceded by elongate pits; S2 evenly convex in basal half.

Distribution. China: Guangdong; Laos; Vietnam * ( Giordani Soika 1941; Gusenleitner 2001) ( Fig. 10 ).

Notes. Gusenleitner (2001) described Pseudonortonia crassipunctata comparing it to P. bhamensis , but also mentioning that the very small F10–11 of the male were like those observed in P. abbreviaticornis . Comparison of the holotype of P. crassipunctata with specimens of P. abbreviaticornis from Guangdong, including the lectotype, revealed in fact that the two taxa correspond in all characters, making the former a junior synonym. Photos of the holotype of P. crassipunctata are available at ZOBODAT (2023).
