Note
Blackwall (1865)
indicated one female as the
type
material used in the description of
Ctenus velox
, but two adult females were found in the OUMNH collection and, according to the label, both were designated as
types
. Based on the original description we here designate the smaller specimen as the
lectotype
and the other female as the
paralectotype
.
Diagnosis
The males of
Afroneutria velox
comb. nov.
differ from males of the other species of the genus by the laminar and truncated tip and the additional subdistal projection of the embolus (
Fig. 1
B) and the shape of the RTA (
Fig. 3
A–C). The females can be distinguished from the remaining species of the genus by the acuminated and short lateral projections of the epigynum and rounded dorsal spermathecae in the vulva (
Fig. 3
D–E).
