Remarks
. This species was described by Johnson on the basis of a single female from the Baie d’Antongil, Ambohitsitondroina, leg. J.Vadon, ‘lavage de terre’,
1100 m
,
January 1953
. The short description states that the base of the pronotum is ‘much broader’ than the elytra, which is confirmed by the accompanying photograph, and he placed the species provisionally in s.str.
Flachiana
. In his notes presented to the writer, however, he records
19 specimens
from Plateau de
Tampoketsae
, leg H.Franz,
1500 m
, mountain forest,
11 April 1969
as being this species, and states ‘There is no difference in the relative breadths of the pronotum and elytra, the
type
specimen being aberrant (as well as badly mounted) in this respect.’
