Ischnocolus hancocki Smith 1990: 127 , f. 803–818 (Df).

Type material

Holotype female ( BMNH 1990.10.15.2) from El Araich, Morocco, examined.

Additional material

MOROCCO: El Araich: 1f ( ZMUC 8166); 1f ( ZMUC 8169); 1f ( ZMUC 8167); 1f ( ZMUC 8168); 1f and juveniles ( ZMUC 620).

Diagnosis

Female representatives can be distinguished from congeners by the triangular apical segment of the posterior lateral spinnerets and by the spermathecae formed by triangular receptacula lacking lobes ( Figure 4A ). Males unknown.
