Anoplodactylus pygmaeus

(Hodge, 1864)

Body more or less slender, with comparatively long lateral processes. The general shape is more compact than Anoplodactylus petiolatus . Cephalon broad. Abdomen approximately twice as long as the last pair of lateral processes. A small dorsal protuberance on each lateral process, each with a terminal spine.
Ocular tubercle located at the extremity of the frontal part, long and well developed. Proboscis issuing from the ventral side of the cephalon, rounded at the end, with a subterminal constriction, directed obliquely downwards. Chelifores comparatively feeble, covered with hair, having the chela small and the fingers scarcely forcipate. Palps absent.
Ovigerous legs in male only, with six segments; terminal segment very small, bristle-bearing, without any claw.
Ambulatory legs slender, more or less elongate, sparingly hair-beset; tarsus very short; propodus produced, with two spines on the heel, and one or two spines and a long cutting lamella on the sole; terminal claw elongate and sickle-shaped; auxiliary claws rudimentary.
Colour usually pale straw or colourless. Length of the body, taken from the tip of the proboscis to the posterior end of the abdomen up to 1 mm, with legs two and a half times as long.

A shallow-water species.
