Arapari gen. nov.

Type species: Arapari bellus sp. nov.

Etymology. Arapari , called “Cruzeiro do Sul” (Southern Cross) in Tupi-Guarani language; allusive to the metallic bright of the type species. Masculine gender.

Integument metallic. Frons distinctly wider than long. Antennal tubercles distant from each other. Distance between upper eye lobes greater than 3.0 times width of lobe; lower eye lobes occupy most of side of head. Genae rounded at apex.

Last segment of palpi fusiform. Antennae with eleven segments; not reach elytral apex; scape conical, not exceed anterior margin of prothorax, without dorsal depression; antennomere III without dorso-longitudinal sulcus; antennomeres V–X serrate. Mandibles short, approximately as long as length of frons.

Prothorax cylindrical, slightly wider than long; lateral tubercle slightly indicate; lateral margins slightly convergent forward. Prosternum in males with evident sexual punctation. Scutellum small, longitudinally depressed. Elytra approximately 3.5 times as long as length of prothorax; lateral margins subparallel; surface densely punctate; apex unarmed, subtruncate.

Profemora fusiform; mesofemora subclavate; metafemora distinctly long (approximately 2.0 times as long as length of mesofemora), subclavate. Metatarsomere I distinctly longer than metatarsomeres II and III together.

Remarks. Arapari was provisionally included in Trachyderini based on similarities with males of some species of this tribe and, at the same time, absolute impossibility of inclusion in other tribes of Cerambycinae . Since there is no feature that defines males of Trachyderini , it is not possible to be absolutely sure.

Arapari resembles some genera with metallic integument. It differs from Neochrysoprasis Franz, 1969 as follows: antennae not reach elytral apex in males (notably exceed in Neochrysoprasis ); prothorax with lateral tubercle slightly indicate (very distinct in Neochrysoprasis ); scutellum short (distinctly elongate in Neochrysoprasis ).

It differs from Unachlorus Martins & Galileo, 2008 as follows: base of antennal tubercles far away from each other (next to each other in Unachlorus ); antennae not reaching elytral apex (distinctly exceed in Unachlorus ); prothorax with lateral tubercle slightly indicate (very distinct in Unachlorus ); metatarsomere I longer than metatarsomeres II and III together (subequal length in Unachlorus ).

It differs from Weyrauchia Tippmann, 1953 by the antennae, in both sexes, not reaching elytral apex (they distinctly exceed in males of Weyrauchia ), by the antennomeres V–X serrate (filiform in Weyrauchia ), and by the metafemora exceeding elytral apex (not exceed in Weyrauchia ).

It differs from Chlorotherion Zajciw, 1962 by the prothorax with lateral tubercle slightly distinct (very distinct in Chlorotherion ), by the metafemora approximately twice as long as length of mesofemora (distinctly shorter in Chlorotherion —less than 1.5 times length of mesofemora).

It differs from Micropelta Zajciw, 1961 by the scape without dorsal-basal depression (present in Micropelta ), by the antennomere III without dorsal sulcus (present in Micropelta ), by the prothorax with lateral tubercle slightly indicated (very distinct in Micropelta ), and by the pronotum punctate, without distinct tubercles on disk (transversely striate, with distinct tubercles on disk in Micropelta ).

Arapari differs from Neogalissus Monné & Martins, 1981 by the antennae not reaching elytral apex (distinctly exceed in Neogalissus ), by the antennomeres V–X serrate (filiform in Neogalissus ), and by the metafemora distinctly longer than mesofemora (slightly longer in Neogalissus ).

It differs from type species of Zenochloris Bates, 1885 ( Zenochloris is markedly heterogeneous, including species with different types of antennae, prothorax and tarsomeres) by the prothorax with lateral tubercle slightly distinct (different in Z. paradoxa Bates, 1885 ).

Arapari is also similar to species of Eriphus Audinet-Serville, 1834 , which have bodies with a metallic color, but differs by the prothorax with lateral tubercle slightly distinct (more conspicuous in species of Eriphus ), and slightly narrowed forward (more distinctly narrowed forward in species of Eriphus ).
