Tobochares sp. A
Material examined
(1). VENEZUELA: Amazonas: Tobogan de la Selva, leg. M. Balke (1 female, SEMC; DNA voucher SLE526).
Differential diagnosis.
This species is morphologically very similar to
T. pallidus
, and shares most diagnostic features of that species (in particular its very pale coloration). This species can be separated from
T. pallidus
by the faint but distinctly impressed striae in the posterior quarter of the elytra, and the slightly less emarginated eyes.

Remarks.
This species is only known from a single specimen, which we also extracted for DNA. Molecular data also supports this taxon as sister to
T. pallidus
, to which it is also similar morphologically. We refrain from describing the species until additional specimens, including ideally a male, can be found.
