Remarks.
BOHEMAN (1855)
described
Coptocycla rubrotestacea
presumably from a single specimen. Subsequently, the species was listed only in catalogues (see BOROWEC 1999a) and
BOROWIEC (1989)
synonymized it with
Charidotella ventricosa
(
Boheman, 1855
)
. However,
C. rubrotestacea
differs by the uniformly pale explanate margin of elytra (humeral spots always present in
C. ventricosa
), subcircular body shape (subtriangular in
C. ventricosa
), clypeus with an apical sulcus (smooth in
C. ventricosa
), and less convex elytra with much lower and obtuse postscutellar tubercle (high and sharp in
C. ventricosa
). I therefore restore the species status of
C. rubrotestacea
. The quite unusual combination of morphological features of this species is similar only to
Charidotella morio
(Fabricius, 1801)
, which differs by the primarily black ventral side (uniformly yellow in
C. rubrotestacea
), explanate margin of elytra declivous in their entire length (canaliculate in apical third in
C. rubrotestacea
), more constricted pronotum in its basal half, thus appearing subpentagonal (broadly rounded and nearly semicircular in
C. rubrotestacea
), and large basal teeth of claws (small in
C. rubrotestacea
).
Charidotella rubrotestacea
is so far known only from the
holotype
.
Distribution.
