Remarks and comparative notes
Numerous specimens from the Ditsong National Museum of Natural History (Pretoria), were, at first sight, considered to belong to one, or even several, new species. Examination of the aedeagi revealed, however, no differences sufficient for a separation of these forms from
P. laetulus
(
Fig. 7
E–G). Unless reliable diagnostic differences dictate otherwise, it is considered appropriate to treat
P. laetulus
as a species that shows significant variability.
Fig. 7A–D
shows the pronota of specimens from different locations to illustrate individual variations.

A

B
. Cape Province, South Africa.
C
. KwaZulu-Natal, South Africa.
D
. Mpumalanga, South Africa.
E–F
. Aedeagus of specimen from Mahe, Seychelles (E = dorsal, F = ventral view).
G
. Aedeagus of specimen from Mpumalanga, South Africa, dorsal view. Scale lines: A–D = 0.5 mm, E–G = 0.2 mm.
One of the Malvern specimens (KwaZulu Natal Province of
South Africa
) collected by Marshall in 1897 (BMNH) bears a
type
label by A. Grouvelle, with the name ‘
Psammoecus distinctus
’. Since no description of a taxon with that name is available, the name is to be considered a manuscript name.
