Ubick , W. Rauscher ( CAS ) .

Etymology : The species epithet recognizes the collector, Darrell Ubick of the California Academy of Sciences.

Legpairs one and two reduced, three to seven enlarged, with elongate tarsi, large fungiform knobs basal on femora seven, mesodistal low swellings on femora 6, knobs of femora seven roughened by small teeth ( Figs. 53–57 ). Anterior gonopods ( Fig. 51 ) simple, slender, tapering, slightly hooked apically, with subapical posterior tooth. Posterior gonopod coxites ( Fig. 52 ) bearing short, curved fimbriate branch midlength, terminating in small, bifurcate process. Legpair 10 coxae of normal size, with small glands, legpair 11 femora with blunt, dorsally directed knobs. Distribution : known only from the type locality. Notes : C alityla ubicki would seem to have some adaptation to cave life, with reduced eyes and pigment and somewhat elongate leg tarsi.
