DIAGNOSIS. — Cornea subglobular. A2 protopod with flattened, articulated plate on inner dorsal margin. Raptorial claw with terminal ischiomeral articulation; propodus pectinate, with one movable spine proximally; dactylus with two teeth, uninflated basally. Abdominal somites subcylindrical in cross-section, without dorsal carinae; articulation compact. Telson with distinct MD carina, short anterior SM carinae, minute SM and two IM denticles. Uropodal protopod with one primary spine; exopod segments with terminal articulation.

REMARKS
The specimen agrees well with the
holotype
(tl 17) but shows several size related differences: the rostral plate is slightly broader, the median carina on the telson is sharper, and four instead of three movable spines are present on the outer margin of the uropodal exopod. The present specimen is female and the type series is based on subadults (and possibly some postlarvae), so the adult morphology of the endopod of the male first pleopod remains uncertain.
According to
Moosa’s (1991)
account,
Alainosquilla
resembles eurysquillids in having a depressed, loosely articulated body, and resembles gonodactylids in bearing a fixed dorsal process on the antennal protopod and in having subterminally articulated uropodal exopod segments. Re-examination of the
type
material along with the present specimen shows that the body is strongly convex with compact articulation, the dorsal process on the antennal protopod is articulated and the uropodal exopod segments are terminally articulated, as in hemisquillids and pseudosquillids.
Alainosquilla foresti
is rediagnosed above.
