This species was also examined by Hancock (1907) who added new information. The only specimen known of the type series is housed at the NMW Vienna Museum was classified as syntype ( Paris 1994; Cigliano et al. 2018) ( Fig. 10 ) however there is no indication of other specimens and this specimen is a holotype. Regarding this specimen, in ventral view there is a longitudinal suture on the subgenital plate ( Fig. 10D ).
