Diagnosis and comments
It differs from the other
Tropicis
by the six longitudinal keels at elytra, most conspicuous at the apical half, and the coarse pronotal punctation with coalescent punctures. It most resembles
Trop. flexicarinatus
, but do not co-occur with it (see
Fig. 158
). The species is variable morphologically and may be a complex of close related species.
Lesne (1917)
reported
Cis sexcarinatus
Waterhouse
from
Mauritius
,
La Reunión
,
Madagascar
and
Seychelles
, before
Scott (1926)
erected the genus
Tropicis
based on this species and other two species from
Seychelles
. The specimens of
Lesne (1917)
from
La Reunión
were collected in
Microporus affinis
(cited as
Polyporus microloma
), being the unique record of host-fungus for
Trop. sexcarinatus
. The record of the species from
Seychelles
should be considered with care: it may refer to
Trop. flexicarinatus
, a morphologically similar species described by
Scott (1926)
. The record from
Madagascar
may be correct, as that is very close to
Mauritius
and
La Reunión
, but it should be checked.
