Details About Males
Description:
Adult males can be distinguished from other species of Neoantistea (except N. alachua and N. oklahomensis) by the presence of a tibial apophysis with its lower 2/3 almost perpendicular to the tibia and by a narrow, curved spur on the patella of the palp about 1/2 as long as the tibial apophysis (Opell & Beatty, 1976). Most specimens have 3 retromarginal teeth on each chelicera.
Male Dimensions:
A+B = 3.21 mm
A = 1.35 mm
C = 1.16 mm
