Neocteniza coylei Goloboff & Platnick, 1992 Figures 4-6

Neocteniza coylei Goloboff & Platnick, 1992: 4 , f. 7-11 (Df).

Diagnosis: It partially resembles Neocteniza fantastica Platnick & Shadab, 1976 , and Neocteniza minima Goloboff, 1987 in the structural form of the cymbia, palpal bulb and the presence of ventral spines on the palpal tibia and differs by dilation in the femurs of legs I and II (dilated in the femur of leg III in N. fantastica ). Furthermore, it differs in the color pattern on the anterior and posterior legs, as well as in the number and arrangement of spines on the palpal tibia of males ( Figure 5 ).
