species:
Saprinus rubripes
Erichson, 1834
, original designation.
Diagnosis.
The subgenus
Nessus
differs from the subgenera
Hypocacculus
and
Colpellus
by densely and usually coarsely punctated frontal disc, often with shallow irregular rugae (frontal disc occasionally coarsely granulate, especially in several species from the Afrotropical
Region
); frontal stria usually well impressed, curved or straight, in most cases interrupted behind eyes; supraorbital stria usually absent.
Biology.
As it is common with this genus, members of this subgenus are mostly found on carrion and in dung, excrements, etc. Several species are apparently psammophilous (e.g.
Hypocacculus
(
Nessus
)
eremobius
Reichardt, 1932
).
Distribution.
This subgenus includes the bulk (about 54 species) of representatives of the genus
Hypocacculus
, and is especially species-rich in the Afrotropical Region. Several species occur as far east as
India
and
Sri Lanka
.
Hypocacculus
(
Nessus
)
interpunctatus
has been introduced into
Australia
(

).

Notes on the taxonomic status of
Hypocacculus
(
Nessus
)
grosclaudei
.
Hypocacculus (
N.
)
grosclaudei
has been originally described in the genus
Exaesiopus
. However,
PEYERIMHOFF (1936)
proposed to include it in the genus
Hypocacculus
, subgenus
Nessus
. Although KRYZHA- NOVSKIJ & REICHARDT (1976) likewise objected placing it in
Exaesiopus
,
MAZUR (1984
,
1997
) left its taxonomic status unchanged. After examining several specimens of this species (one of them has been compared with the
type
species by Peyerimhoff (
MNHN
)) the opinion of
PEYERIMHOFF (1936)
is upheld in this work.
