Vervoort, 1949
Short Description:
Pseudochirella gibbera is an aetideid calanoid copepod known after female (5.50 mm in length) from the Timor Sea.
Taxonomic Description:
Female. (Description after Vervoort (1949) with modifications). Total length 5.50 mm. Cephalothorax 4.26 times longer than abdomen. Th5 posterior corners asymmetrical: left corner rounded, right one supplied with spine. Genital segment abruptly asymmetrical, much wider than long; right side with large projection covered with hairs distally, on the left there is also projection, but smaller in size (dorsal view). Oral parts similar to that in P. obtusa. Re P1 3-segmented. Ri P2 (?) one-segmented. P4 coxopodite with 5 strong, pointed spines.
Remarks. Grice and Hulsemann (1967) had attributed their specimens to present species, but this attribution may be doubtful, because the authors recorded the absence of spine on Th5 posterior corner. The latter feature is very important in identification of species of Pseudochirella .
