Dubiostalon inusitatus Szelényi, 1981b: 293 .

Material examined ( HNHM). Holotype (♂): “HUNGARIA Hortobagy, Zám. 1975. VI. 16-18 leg. Kaszab & Mahunka.” / “Hym. Typ. No. 6826 Mus. Budapest.”

Remarks. The monospecific genus Dubiostalon was originally described as representing a potential new tribe of Tetrastichinae , distinguished in part by having a 7-segmented funicle ( Szelényi 1981b). However, the antenna in D. inusitatus should be interpreted as having seven elongate flagellomeres that are not distinctly segregated into funicular versus claval segments ( Fig. 26). This type of antenna is not uncommon for male Neotrichoporoides ( Graham 1987) , and Dubiostalon is here synonymized under Neotrichoporoides because it does not differ from the definition of the latter genus provided by Graham (1987).

The ventral plaque of the scape is relatively small and situated mainly in the apical half of the scape, although the two antennae on the holotype vary in the placement of the plaque ( Fig. 27). The space between the submedian scutellar grooves is very narrow ( Fig. 28), and the body is relatively dark ( Fig. 25). In Graham’s (1987) revision of Tetrastichinae , it keys with difficulty to Neotrichoporoides cavigena Graham. It is similar to N. cavigena in nearly all characters, but differs at least in that the propodeal spiracle of N. inusitatus is adjacent to the metanotum instead of separate from it ( Fig. 30). Given that some other species similar to N. cavigena have been more recently described ( Kostjukov 2004; Yegorenkova & Kostjukov 2006), the species should be kept distinct until they can be examined together.
