Epitarsipus
Le Cerf, 1922
stat. rev.
Type species:
Epitarsipus rufithorax
Le Cerf, 1922
, by original designation.
Le Cerf (1922)
described
Epitarsipus
and the single species
E. rufithorax
on the basis of one male and one female. Later
Viette ([1955]
: 92, 1957: 94, 1982: 28) regarded
Epitarsipus
Le Cerf, 1922
a
synonym of
Malgassesia
. However, the external characters and the genitalia of the
type
species of genera,
Epitarsipus rufithorax
and
Malgassesia rufescens
(figured by
Viette 1982
: 28, 32 and 20, 21), differ to such an extent, that the synonymy cannot be confirmed. The most important differential characters between
Epitarsipus
and
Malgassesia
are:
Epitarsipus
with antenna narrow, minimally clavate (distally broader, clearly clavate in
Malgassesia
); first tarsomere of hindleg distinctly elongated (not in
Malgassesia
); male genitalia with crista sacculi of valva uniquely bipartite, consisting of a flat and broad part medio-basally and an elevated, bulbous part at the ventral margin (crista sacculi simple, broad and flat in
Malgassesia
); phallus simple (distal part very long and slender in
Malgassesia
); female with ovipositor long and narrow (short and thick in
Malgassesia
); antrum weakly sclerotized, simple, long and continuously narrow (strongly sclerotized, broader and medially narrowed in
Malgassesia
); ductus bursae enlarged with numerous longitudinal folds (narrow, without folds or other specialization in
Malgassesia
). As long as no other species with intermediate characters become known, I regard
Epitarsipus
stat. rev.
a valid genus containing a single species,
E. rufithorax
