Eclipta dendensis Nascimento & Santos Silva, 2017 (nomen nudum) is validated. The Neotropical Eclipta Bates, 1873, together with five other genera, composes a generic complex in Rhinotragini, which were previously allocated in Ommata White, 1855. In Brazil, many species of Eclipta are distributed in the Amazon and Atlantic forest regions. In this work, Eclipta dendensis sp. nov. from the Brazilian Atlantic Forest is described and illustrated.

KEYWORDS: Neotropical region; South America; taxonomy

For the purpose of following the rules of the ICZN (1999) concerning on works issued and distributed electronically (Art. 8.5.2; 8.5.3), the work by Nascimento & Santos-Silva (2017) is republished. The following text was copied from Nascimento & Santos-Silva (2017.

Ommata White, 1855 was divided by Bates (1873) in three groups of species, based primarily on the shape of the legs. The first group included the species with “Legs long and slender; middle femora gradually and moderately clavate”. This group included four 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 and apex truncated. Finally, the third group included Agaone Pascoe, 1859, with legs robust, middle femora abruptly and very thickly clavate, first joint of hind tarsi greatly elongated and elytra entire.

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 false, as we could see in 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 difference in the shape of mesofemora is not true, and it is very variable in the species currently placed in Eclipta and Chrysaethe, originally allocated in these genera by Bates (1873).

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.

The new species agrees moderately well with the type species of Eclipta (Ommata (Eclipta) flavicollisBates, 1873), mainly by the antennal, pronotal, elytral and legs shape. Thus, we are describing it in Eclipta.

According to Monné (2017), EcliptaBates, 1873 includes 58 species distributed from Mexico to southern South America. In Brazil, the species of Eclipta are distributed mainly in the Atlantic forest and some species also inhabit the Amazonian regions. The new species was described based on a specimen from the Atlantic Forest in the Bahia state, Northeast Brazil.


Photographs were taken in the MZSP (Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil) with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in “mm” using a micrometer ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope.

Dimensions in mm (holotype ♀). Total length (from mandibular apex to abdominal apex), 8.55; prothorax: length, 1.75; basal width, 1.26; distal width, 1.25; widest prothoracic width, 1.45; humeral width, 1.60; elytral length, 5.00.

Type material. Holotype female from BRAZIL, Bahia: Igrapiúna (Reserva Ecológica da Michelin, Pacangê; 13°50’16.0”S / 39°14’28.9”W; 139 m), 21-22.V.2012, M. Aragão, E. Menezes & E. Mota col. (MZSP).

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 edge of the elytra parallel-sided; distal third of the elytra not dehiscent; elytra not narrowed toward apex from midlength; elytral apex reaching apex of fourth abdominal segment; apex of metafemora slightly surpassing elytral apex. In E. eirene, the distal antennomeres are not ringed, pronotum is moderately finely and abundantly punctate, distal 2/3 of outer edge of the elytra is somewhat concave, distal third of the elytra is dehiscent, elytra narrowed toward apex from midlength, elytral apex reaching at about midlength of third abdominal segment (sometimes the apex of third segment and apex of metafemora distinctly surpasses the elytral apex). It also resembles E. thoracica (Bates, 1873), but differs mainly by the metatarsi mostly pale yellow which is darker in E. thoracica.
