Paralimnadia marplesi (Timms and McLay, 2020) Timms & Rogers, 2020

Timms, Brian V. & Rogers, D. Christopher, 2020, Fig. 5 in Paralbunea dayriti, Zoological Studies (Zool. Stud.) 59 (38), pp. 1-10 : 6

Paralimnadia marplesi comb. nov.

= Eulimnadia marplesi Timms and McLay, 2005: 409–414 , Figs. 1–4

Comments: This New Zealand species also lacks a true subcercopodal spiniform process, instead having a triangular process ( Timms and McLay 2005, Figs. 2G , 3C ). Moreover, its cercopod spinal position is at 50% of the cercopod length, there are 9–12 antennomeres per flagellum, and in the only collection available there are nine males and two females, hardly a ratio expected for Eulimnadia , but indicative that gonochoristic reproduction is likely. There is a small mound on the endite IV corm medial surface, again not definitive. This species has far more affinities with Paralimnadia than Eulimnadia and so should be shifted to Paralimnadia .

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.

Fig. 2. Ventral views of subcercopod spine /projection of representative Australian Eulimnadia and Paralimnadia. A, E. australiensis; B, E. beverleyae; C, E. gnammaphila; D, E. taroomaensis; E, E. uruluensis; F, P. cygnorum; G, E. datsonae; H, E. palustera; J, P stanleyana; K, E. vinculuma. Scale bars = all about 0.4 to 0.6 mm.

Fig. 3. Representative claspers of Eulimnadia and Paralimnadia. A, P. badia (Wolf); B, P. multispinosa; C, E. uluruensis; D, E. dahli; E, E. centenaria. Scale bars = 1 mm.
