Remarks.
BLAKE (1939)
described
Paratrikona rubescens
from Jarabacoa and added that
Darlington
wrote that the specimens were ‘rather deep red with conspicuous white blotches irregularly arranged’ while only slight trace of the white markings remained on the dried specimens; as a result, Blake did not indicate them in her drawings.
BLAKE (1971)
published additional specimens of
P. rubescens
collected at ‘Arroya de Toro, Quebrada Honda’ including a figure showing clear white markings.
BOROWIEC (2009b)
described
P. albomaculata
from Jarabacoa and separated it from other species based on the conspicuous white pattern on elytra.
Paratrikona albomaculata
has clearly marked, contrasting white spots on reddish-brown elytra while the
holotype
of
P. rubescens
has the spots only slightly indicated. Nevertheless, they are on exactly same position as in
P. albomaculata
. Both taxa also have identical punctation of elytra and pronotum, similar convexity of elytra, identical M-shaped black pattern of prontum, and are thus in my opinion conspecific. For these reasons I synonymized
P. albomaculata
with
P. rubescens
.
Distribution.
Endemic to
Dominican Republic
(
BLAKE 1939
,
1971
;
BOROWIEC 2009b
