( Fig. 32 A–H )

Smittia (Smittia) bilobulata Edwards, 1931: 299 .

Pseudosmittia bilobulata (Edwards) ; Paggi 1993: 171.

Allocladius bilobulatus (Edwards) ; Andersen et al. (2010: 6).

Material examined: ARGENTINA: Territorio Rio Negro, Viedma , holotype male, 23.x.1926, F. & M. Edwards (BM 1927–63). Other material as in Andersen et al. (2010) .

Diagnostic characters: The presence of a single pars ventralis ( Fig. 32 C ) together with a thumb-nail like virga ( Fig. 32 B ) will separate the species from other species of the nanseni group.

The species is described in detail in Andersen et al. (2010: 6).
