Neomuelleriella klomax Kornicker 1995

Neomuelleriella klomax

ETYMOLOGY.—From the Greek klomax (heap of stones).

HOLOTYPE.—Adult female on slide and in alcohol in the collection of the Museum of Victoria.

TYPE LOCALITY.—Slope 19, 37°07.30′S, 150°20.20′E, New South Wales, off Eden, depth 520 m.

PARATYPES.—None.

DISTRIBUTION.—Slope 19, 520 m.

DISTRIBUTION.—Off Australia, 363–400 m.

DIAGNOSIS (adult female).—Caudal process of carapace with inner row of broad spinous bristles along list. 1st antenna: medial bristle of 6th joint absent; c-, f-, and g-bristles not claw-like; and d-bristle present. Tip of 7th limb with teeth. Each lamella of furca with 6 claws, without secondary claws between primary claws, and only claw 1 nonarticulated. Genus based mainly on inner bristles of caudal process and distribution of furcal claws.

COMPARISONS.—Only two previous genera have a row of broad spinous bristles along list of caudal process: Cymbicopia and Spinacopia. The furca of Alphasarsiella differs from that of Cymbicopia in having claw 1 rather than claws 1 and 2 nonarticulated, and from Spinacopia in having no secondary claws between main claws. Some species of the genus Parasarsiella Poulsen, 1965:70 have a furca similar to that of Alphasarsiella, but the carapace is without the row of broad spinous bristles along the list of the caudal process. In A. altrix and A. anax the row of bristles on the list extends from the dorsal to ventral margins of the caudal process; whereas, on known species of Spinacopia most bristles are in the dorsal part. A medial bristle is absent on the 6th joint of the 1st antennae of Cymbicopia, Alphasarsiella, and some species of Neomuelleriella, but is present on other genera.
