Diagnosis.
Males of
Celaetycheus aberem
sp. nov.
(
Figs 6A–B
) resemble those of
C. mungunza
sp. nov.
(
Figs 12A–B
) by the large embolus, absence of a tegular projection and a median apophysis curved prolaterally at tip, but can be distinguished by the larger median apophysis (
Fig. 6A
). Females of
C. aberem
sp. nov.
(
Figs 6C–D
) can be distinguished from the remaining species of the genus by the subquadrangular shape of the median sector of the epigynum (
Fig. 6C
).
