Comments: This species lacks a true spiniform subcercopodal process, instead having a rounded process covered in short spines, as observed in some juvenile Eulimnadia species (DCR personal observation). The cercopod spine is placed at about 40% of the cercopod length, and there are 13 antennomeres on each flagellum ( Table 2). Amplexus position and sex ratios are unknown.

Figures

Fig. 1. Representative male cercopods of Australian Eulimnadia and Paralimnadia. A, P. stanleyana (King) (typical sub-basal area of cercopod in Paralimnadia); B, E. gnammaphila (typical sub-basal cercopod spiniform spine in Eulimnadia); C, P. hyposalina; D, P. montana; E, E. feriensis; F, E. vinculuma; G, E. datsonae; H, E. palustrea. Cercopods range in length from 1.2 to 1.5 mm and have plumose setae dorsally except P. montana which has spines.
