Original description (Lewis, 1898). "Elongatum,
subparallelum, convexum, nigrum, nitidum; fronte impressa, stria
integra, pronoto disco bipunctato, stria marginali lateralibus
valida, antice integra, basi in medio vix interrupta; elytris
striis 1 3 integris, 4 5 dimidiatis; propygidio pygidioque
planis, punctatis; prosterno angustato haud striato; mesosterno
emarginato, stria marginali integra; tibiis late dilatatis. L.
7.1/2 mill.
Elongate, somewhat parallel, convex, black and shining; the head
smooth, stria well-marked over the eyes, complete anteriorly,
but fine and irregular, sinuous in the middle, impressed anteriorly;
the thorax, marginal stria strong at the sides, fine but complete
behind the head, and at the base it is continued until it is narrowly
interrupted before the scutellum, on the disc are two small but
very distinct punctures, which with the antescutellar point form
a triangular arrangement, thus ; the elytra, the epipleura
striae are cariniform and complete, humeral short, fine, and oblique,
striae 1 3 strong and complete, 4 apical and dimidiate,
5 similar but a little shorter; the propygidium and pygidium are
flat and rather densely punctate; the prosternum impunctate, keel
narrow except at the base; the mesosternum emarginate anteriorly,
marginal stria complete and well defined; the tibiae are all greatly
dilated, anterior pair 4-dentate, intermediate and posterior 4-spinose.
Platysoma palmipes, Lew., and P. extrarium, Lew., are somewhat
similar to the species above, but they are less elongate. In P.
palmipes the tarsi are short, but in P. extrarium and P. pinnigerum
they are of normal length and not very dissimilar to those of
P. ovatum, Er.
