Cg4 is (1) absent in M. ponderi, (2) clearly pos- terior to suture C2/C3 but still close to it in M. (M.) thienemanni and M.

Ac. Three pairs of Ac of equal size in Mamersella () and in some of the species "incertae ; Gap be- tween first and second Ac longer than length of Ac in M () ponderi Hsiryey, 1990. I-L-6. Simple claws, hook-like and (1) without ven- tral or dorsal clawlets in Mamersella (), (2) with FIG. 82. Mamersella thienemanni: Anterior portion of dorsal shield with nasal plate and eye region (top), dorsum (bottom). Note: the two figures are turned by 180° against one another [DS = dorsal shield]. dorsal clawlet in M. () ponderi, and (3) with ventral clawlets and dorsal clawlet in M. () mesoamericana. IV-L-6. Without swimming hairs. With claws reduced or small and (1) without long terminal seta in Ma- mersella (), or (2) with long terminal seta in the other species. Palpus. Palpus (1) "anisitsiellid-like" and slender in Mamersella () and M. () ponderi, or (2) "anisit- siellid-like" and robust in M. () mesoamericana. Discussion of species In this study, the two species M. thienemanni d^nA M. maryellenae are placed in the subgenus Mamersella (). They are similar to each other regarding shape and chaetotaxy of palps and legs, shape of coxae and chelicera (see figures above). M. mesoamericana and M. ponderi are placed in this study as species "incertae ; They show more similarities to certain m
