Iheringia New species of Eclipta from the Brazilian Atlantic Rainforest ( Coleoptera , Cerambycidae , Cerambycinae , Rhinotragini )

In this work, a new species of cerambycid beetles is described and illustrated: Eclipta dendensis sp. nov., from the state of Bahia, Brazil.

According to Monné (2016), Eclipta Bates, 1873 includes 58 species distributed from Mexico to southern South America.Bates (1873) divided Ommata White, 1855 in 3 groups of species, based primarily on the shape of the legs.The fi rst group included the species with "Legs long and slender; middle femora gradually and moderately clavate".This group included 4 subgroups, characterized by the elytral shape: Phoenissa, Chrysaethe, Ommata, and Rhopalessa.The second group included the species with "Legs slender; middle femora abruptly but not very broadly clavate; elytra with sides subparallel, apex truncated".Finally, the third group included species with "Legs robust; middle femora abruptly and very thickly clavate; fi rst joint of hind tarsi greatly elongated; elytra entire", that included only Agaone Pascoe, 1859.Currently, Chrysaethe, Ommata, Rhopalessa, Eclipta, Phoenissa (= Oregostoma Audinet-Serville, 1833) and Agaone are considered distinct genera.Notwithstanding, the division between "legs long and slender" and "legs long" is completely subjective and not true and we see the species allocated in each group by Bates (1873).For example, the legs in Ommata (Eclipta) eirene (Newman, 1841) (currently, Eclipta eirene), are long and slender, exactly as in Ommata (Chrysaethe) beltiana Bates, 1872 (currently, Chrysaethe beltiana).In the same way, the diff erence in the shape of mesofemora is not true, and it is very variable in the species currently placed in Eclipta (even in species originally placed in this genus by Bates, 1873) and Chrysaethe.
As Eclipta and Chrysaethe have the elytral apex truncate, and the elytra is very variable in the species placed in Eclipta by Bates (1873), it is absolutely impossible to separate these genera based on the features originally included.However, the type species of each genus, designated by Peñaherrera-Leiva & Tavakilian (2004), allow separating them (notably by the pronotal shape), although it would be necessary a complete revision of these genera to correctly place each species currently in them.
The new species agrees moderately well with the type species of Eclipta [Ommata (Eclipta) fl avicollis Bates, 1873], mainly by the antennal, pronotal, elytral and legs shape.Thus, we are describing it in Eclipta.

MATERIAL AND METHODS
Photographs were taken in the MZSP with macro lens, controlled by Zerene Stacker AutoMontage software.Measurements were taken in "mm" using an ocular micrometer and stereomicroscope, was also used in the study of the specimen.

Eclipta dendensis sp. nov.
(Figs 1-4) urn:lsid:zoobank.org:pub:0955960C-B4BA-452D-9301-1BD0E13A69B6 Female.Integument black with greenish or violaceous refl ections on some areas; antennomere VIII with dark reddish-brown ring on basal quarter; antennomere IX with reddish-brown ring on basal quarter, more yellowish ventrally; antennomeres X-XI with pale yellow ring on basal third; pronotum yellow except transverse reddish-brown band close to distal margin; sides of prothorax mostly yellow except black area close to procoxal cavity, reddish-brown basal area and black distal area, and irregular reddish-brown macula on distal third; elytra with small reddish macula on sides of humeri; metacoxae brown maculated with reddishbrown areas; metatrochanters yellowish-brown; distal 2/3 of metatarsomere I and entire surface of II pale yellow; metatarsomere III reddish-brown on basal half, brown on lobes; metatarsomere IV reddish-brown; basal half of metatarsomere V reddish-brown, distal half dark brown; basal projection of abdominal ventrite I pale yellow.
Etymology.The name refers to the region where the holotype was collected, popularly known as Costa do Dendê.
Remarks.Eclipta dendensis sp.nov.resembles E. eirene (Newman, 1841) by the metatarsi mostly pale yellow, but differs as follows (female): distal antennomeres with basal light ring; pronotum coarsely punctate-reticulate; distal 2/3 of outer side of the elytra parallel-sided; sutural distal third of the elytra not dehiscent; elytra not narrowed toward apex from midlength; apex of metafemora slightly surpassing elytral apex; elytral apex reaching apex of fourth abdominal segment.In E. eirene, the distal antennomeres are not ringed, pronotum is moderately finely and abundantly punctate, the distal 2/3 of outer side of the elytra is somewhat concave, distal third of the sutural angle of the elytra is dehiscent, elytra narrowed toward apex from midlength, apex of metafemora distinctly surpasses the elytral apex, and elytral apex reaching at about midlength of third abdominal segment (sometimes the apex of third segment).It differs from E. thoracica (Bates, 1873), but differs mainly by the metatarsi mostly pale yellow (dark in E. thoracica).
