Pseudeburia, a New South American genus of longhorned beetle (Cerambycidae: Cerambycinae: Bothriospilini)

Based on the terminalia structures, the species Eburia albolineata Fisher 1944 is transferred from Eburiini (Cerambycoinia) to Bothriospilini (Trachyderoinia) in a new genus: Pseudeburia gen. nov. http://zoobank.org/urn:lsid:zoobank.org:pub:1C803D54-8B84-4800-A91B-04F5EC8DBA8D

The subfamily Cerambycinae is divided into two supertribes: Cerambycoinia and Trachyderoinia, this division was proposed by Fragoso et al. (1987) based on the structure of the terminalia. Lacordaire (1869) subdivided the 'cerambycides vrais sylvains' into two sections according to the diameter of the ommatidial lenses (i.e. coarsely and finely faceted eyes). The proposal of Fragoso et al. (1987) is contrary to Lacordaire's classification; Fragoso et al. (1987) proposed that terminalia differentiation preceded the transformation of the ommatidia, a trend that occurred independently in many groups of Cerambycinae.
The differentiation of terminalia between these two supertribes is as follows: in Cerambycoinia females the ovipositor is elongate (longer than sternites VI and VII together), clearly divided into an anterior and posterior region; in females, sternite VIII is not modified and in males sternite VIII has a long apodeme. The supertribe Trachyderoinia was erected to include the taxa in which females possess purpuriceniform terminalia, characterized by a short ovipositor (shorter than or equal to sternites VI and VII together), sternite VIII with a brush of differentiated setae and tergite VIII bi-or trilobate; in males sternite VIII is wider than long with a very short or absent apodeme (Fragoso et al. 1987). This Trachyderoinia terminalia pattern has been described in many works: Moura and Galileo (1992), Monné and Napp (2000), Monné (2005b), Monné and Napp (2005), Botero and Monné (2012), and Quintino and Monné (2014).
Members of the tribe Eburiini possess terminalia of the Cerambycoinia pattern and the tribe is therefore placed in this supertribe. Studying material of tribe I provided the opportunity to examine the terminalia of many Eburiini genera and all of them present this pattern. I observed that the terminalia of Eburia albolineata Fisher 1944 is actually purpuriceniform, necessitating the transfer of this species to Trachyderoinia and its inclusion in a new genus, Pseudeburia gen. nov., in the tribe Bothriospilini.

Prothorax rounded at sides, with a short, acute, median-lateral spine. Pronotum with two antemedian tubercles, rounded at top; with a median longitudinal gibbosity, slightly elevated. Procoxal cavity rounded, not angulated at sides. Prosternal process narrow, about one-third as wide as procoxal cavity. Mesosternal process tuberculated, mesocoxal cavities about 1.5 times width of mesosternal process. Prosternal and mesosternal process with lateral projections that fit into notches on coxae.
Scutellum small, rounded at apex. Elytra convex, parallel-sided, elongate, at least three times as long as the width across humeri, with eburneus callosities. Apex truncated, bispinose, external spine longer than inner spine.
Mesotibiae, metatibiae and femora linear, inner apex of mesotibiae and metatibiae with a long and acute spine (longer than pedicel length), mesotarsomere and metatarsomere I 1.5 times longer than mesotarsomere and metatarsomere II.
Urosternites transverse, subequal in width; urosternite V truncate and sinuous at middle.

Remarks
Eburia albolineata was described by Fisher (1944) based on a unique female, from Caripito, Venezuela, and placed in the tribe Eburiini (Cerambycoinia). The general appearance and especially the eburneus callosities are typical of Eburiini, but examination of the female holotype, and specimens of the MNRJ, showed that the terminalia of Pseudeburia albolineata comb. nov. is purpuriceniform. The differentiation of this type of terminalia is a very complex trend that involves some sternites, not only in the female terminalia but also in the male terminalia and should have evolved only once in Cerambycinae (Fragoso et al. 1987). The eburneus callosities, on the other hand, are a characteristic that occurs in many tribes of Cerambycinae, as for example in Trachyderini, Torneutini, Bothriospilini (Trachyderoinia), Heteropsini and Hesperophanini (Cerambycoinia) and does not occur in all the Eburiinie.g. Styliceps sericata (Pascoe 1859), Simplexeburia divisa Martins and Galileo 2010, Opades costipennis (Buquet 1844).
In Trachyderoinia only two tribes have eyes coarsely faceted, Torneutini and Bothriospilini. Bothriospilini is characterized by the antennae elongate in both sexes, prothorax with lateral projections, procoxal cavities rounded at sides, mesosternal process with lateral projections, mesofemora and metafemora spinose at apex and hind legs twice as long as forelegs (Monné and Napp 2005). All of these characteristics are present in Pseudeburia gen. nov.
Beyond Pseudeburia gen. nov., in Bothriospilini only three genera have eburneus callosities: Bothriospila Aurivillius 1923, Taygayba Martins and Galileo 1998and Timbaraba Monné and Napp 2005. Bothriospila differs from the other genera because its eburneus callosities are irregular and clothed with short pubescence (Monné and Napp 2005). Pseudeburia gen. nov. differs from Taygayba by having the sides of the prothorax armed with an acute spine, by the spinose elytral apices and the inner apices of the mesofemora and metafemora with a long spine. In Taygayba the sides of the prothorax, apices of elytra, and the inner apices of the mesofemora and metafemora are unarmed. Pseudeburia gen. nov. differs from Timbaraba by having the inner apical spine of the mesofemora and metafemora well developed (longer than pedicel length). In Timbaraba the inner apical spine of the mesofemora and metafemora are moderately short (shorter than pedicel length).
