TYPE LOCALITY. — Colombia.
DISTRIBUTION. — Brazil, Colombia, Peru (Amazonian Basin). The specimen from Colombia is not mapped on Fig. 16C View FIG as the data is too vague.
ETYMOLOGY. — This species is named after its very close similarity with Teramocerus pulcher n. comb., making the two species impossible to discriminate without examination of male genitalia.
DIAGNOSIS (MALES). — Elytra and pronotum metallic green; antennomeres much longer than broad; setae on venter of rostrum not reaching prorostrum; apical tooth of elytra rimmed, more or less dorso-ventrally flattened; legs brownish-reddish; first metatarsal segment not carinate on upper side; proximal sclerite of internal sac forming hook with sharp apex.
Measurements. Length of head (rostrum included): 4.5- 10.4 mm; length of body (from front margin of pronotum to apex of elytra): 8.3-15.5 mm; width across humeral calli: 1.3-2.3 mm. Elytra, pronotum and head metallic green; rostrum, antennae, legs and elytral sutura reddish. Habitus: Fig. 6E View FIG .
Head. Prorostrum much shorter than metarostrum and mesorostrum together. Mesorostrum elevated, longitudinally grooved. Metarostrum not grooved, with weak median carina, weakly carinate on sides. Eyes quite large but shorter than or

I am not able to attribute with certainty any of the female Teramocerus examined to this taxon.
SPECIES INCERTAE SEDIS
Two additional species may be part of Teramocerus : Proteramocerus micans Kleine, 1921 and P. nitidus Kleine, 1921 . The type series of these two taxa were already on loan to another person and it was impossible, despite several requests, to have any information or even pictures of these specimens. Both descriptions by Kleine (1921) do not allow knowing the identity of these taxa. Nothing contradicts that they belong to Teramocerus , but also nothing proves it as there is no information about the shape of the scutellum, the base of elytra and the genitalia in the original descriptions. Kleine (1927c) reports P. micans from Costa Rica; as T. suturalis n. comb. is the sole species of the genus Teramocerus known from this country, it is possible that P. micans is its synonym. P. nitidus seems to be quite close to P. micans . Soares & Dias (1971) cite these two species but their descriptions are only translations of Kleine’s text and give no additional information. In the collections of the MNHN, two specimens have an identification label as P. nitidus , written by R. Kleine: one is a female of T. janthinus , the other one is a male of Teramocerus mamillatus Meyer, 1959 … As usual with R. Kleine, identifications in the collections are very fanciful and completely unreliable, even for taxa described by himself. No further information about the identity of P. nitidus can be drawn from these two specimens. Taxa listed in the part material and methods (except for the two species above), and for which the types were not found, very probably do not belong to Teramocerus considering the descriptions and drawings available ( Kleine 1926; Soares 1970; Soares & Scivittaro 1979).
