Males can be distinguished from all species by the ventrally projecting tibial apophysis ( Fig. 7 ). Females are distinguished by the elongated lateral processes of the epigynum, from C. otonga by the triangular median sector of the epigynum ( Fig. 8 ). Description. Male ( holotype ) .

GENITALIA: Epigynum with triangular median sector, apically with wide unsclerotized sector, slightly concave; lateral processes elongated ( Fig. 8 ). Internal genitalia with copulatory ducts elongated, curved; head of spermathecae oval with an apico-lateral pore, base of spermathecae square; fertilization ducts short ( Fig. 9 ). FIGURES 6–9. Chococtenus neblina new species . Male. 6, 7. Female. 8, 9. 6. Palp, ventral view. 7. Palp, retrolateral view. 8. Epigynum, ventral view. 9. Internal genitalia, dorsal view. Abbreviations: Male genitalia: rts, retrolateral tegular swelling. Female genitalia: cd, copulatory ducts; ilp, internal lateral pockets. Natural history. Most specimens where collected in pitfall lines set up between 1997–2225 m , a few where also collected on leaves at night or sifting litter. This species inhabit the cloud forest and qualifies as a cloud forest specialist. Distribution. Only known from the type locality ( Fig. 57 ).
