( Fig. 2 )

Parancistrocerus acclivus Gusenleitner 2007: 97 , 99, ♀ —“ Laos: Lao Pako env., 55 km NE of Vientiane ” (OLML).

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 entirely absent dorsally and forming spiniform teeth on humeri; propodeal shelf shorter than metanotum and shallowly depressed; T1 1.3× as long as apically wide, sparsely punctate with interspaces large and flattened, and with apical margin reflexed; T2 preapically depressed and densely punctate, with reflexed and crenate apical margin; S2 evenly convex.

THAILAND: Chiang Mai, 100 km N of Chiang Mai, Chiang Dao Hill Resort , 540-640 m, 4-11.IX.2016, 1♀ ( MSVI).

Distribution. Laos; Thailand * ( Gusenleitner 2007) ( Fig. 10 ).

Notes. Gusenleitner (2007) described this species in the genus Parancistrocerus Bequaert , but it clearly cannot be assigned to that genus due to the following characters: strongly elongate mesosoma, propodeum with a long horizontal shelf behind metanotum, subpetiolate T1 and absence of a basal acarinarium on T2. These characters support instead the placement of the taxon in the genus Pseudonortonia , where it is morphologically related to P. gujaratica (Nurse) .
