Kontiloleucon n. gen.

Type species. Kontiloleucon australiensis n. gen., n. sp.

Diagnosis. Female and subadult male. Carapace similar to Leucon ; pseudorostrum anteriorly directed. Pereonite 5 without ventral teeth. Subadult male in pre-adult molt with pair of small penial lobes. Adult male. Antennal flagellum extending at least to pleonite 5 or beyond. Pereonite 5 with pair of simple tube-like penial lobes, subequal in length to the basis of pereopod 5. Maxilliped 3 to pereopod 4 with fully developed exopods. With 2 pairs of fully developed pleopods.

Etymology. The new generic name is formed from the combination of the Greek, kontos, meaning long pole, with Leucon . The overall body form of the new genus resembles that found in the genus Leucon , with the addition of a pair of long, simple penial lobes in the adult male, the poles referred to by kontos.

Remarks. There are now several cumacean genera with penial lobes present in the male. Most cumacean penial lobes are simple tube-like structures, with the only exception being Campylaspenis which is described with several setae terminally on the penial lobes ( Băcescu & Muradian 1974). The most similar genus to Kontiloleucon is Phalloleucon , described from the Peru Basin by Mühlenhardt-Siegel (2008), with body form similar to Bytholeucon and in the male a short antennal flagellum, a pair of stout penial lobes broader than the pereopod 5 bases, and one pair of reduced pleopods. In Kontiloleucon the body form is similar to Leucon , and the male has a long antennal flagellum, penial lobes that are approximately the same diameter as the pereopod 5 bases, and two fully developed pairs of pleopods.
