Arenopontia acantha Chappuis, 1954 sensu Božić (1967)

Original description. Božić (1967): 872–873; Fig. 3 (3–4).

Type locality. India, west coast:intertidal locality not specified but probably along the Kerala coast (southwestern India).

Body length. 400 μm (♀).

Remarks. Božić (1967) illustrated the P5 (possibly of the female) and the posterior part of the urosome. From his brief text it appears that identification was made without dissection and based solely on the presence of paired spinous processes on the anal somite and the general morphology of the caudal rami. At that time most currently known species of the acanthus -group were still awaiting description and it is conceivable that Božić (1967) compared his material with N. acanthus only. No reference was made to the number of elements on P3 enp-2 which is of critical importance in resolving its affinities; should only one seta be present on this segment, Božić’s (1967) material may well fall within Wells & Rao’s (1987) proposed taxonomic boundaries of N. indicus .
