Scolioplanes pusilla Sseliwanoff, 1884: 92.

Strigamia pusilla: Bonato et al. 2012: 21; Dányi 2006: 44, figs 1 a – f; Dobroruka 1960: 17.

Material examined.

None.

Diagnosis.

Body length reaching at least 13 mm; number of leg-bearing segments usually 33–37; cephalic capsule longer than wide or as long as wide; antennae short; tergites smooth; coxosternite of first maxillae with a median sulcus; metasternites with mid-longitudinal deep sulcus and two smaller lateral sulci (except ultimate metasternite); metasternite of ultimate leg-bearing segment elongated, narrowing dorsally; coxal pores at least 6 on each coxopleuron; sparse on the ventral surface but dense in lateral margin of the metasternite; anal pores distinct.

Remarks.

As illustrated in fig. 1 d in Dányi (2006), the coxosternite of the first maxillae in this species possesses a median sulcus, a feature not reported in the descriptions or illustrations of other species. Therefore, “ coxosternite of first maxillae with a median sulcus ” is the key diagnostic feature for this species.

Distribution.

Mongolia.
