Neumania (Neumania) liberiensis Cook, 1966

( Figure 20 )

New record. Ghana. 3/2/1, Afiaso stream, Kakum NP, 5°30.087′ N 1°26.373′ W, 114 m

a.s.l., 12 Feb. 2013.

Remarks. The male matches the description of Cook (1966), apart from the apodemes of the anterior coxae. According to Cook, they extend to the anterior part of Cx-IV, the specimens from Ghana have longer apodemes, extending to the middle of Cx-IV. Cook (1966) was uncertain about the assignment of the female, but in my opinion this is correct. Females have the venter with less secondary sclerotization compared to the male, and the apodemes of the anterior coxae extend to the middle of Cx-IV. Some measurements are given below. Males:

Integument smooth. Idiosoma dorsally 437-454 long and 421-441 wide, ventrally 429-470

long. Females: Idiosoma dorsally 514-591 long and 454-531 wide, ventrally 535-591 long.

Distribution. Liberia (Cook 1966), Ghana (this study).
