INTRODUCTION

Hippopsis Lepeletier & Audinet-Serville, 1825 is a large genus of Agapanthiini Mulsant, 1839, including 44 species distributed from Canada to southern South America (Bezark, 2023Bezark, L.G. 2023.

Breuning (1962)Breuning, S. 1962. Révision des Agapanthiini Muls. américains (Col., Cerambycidae). Pesquisas, Porto Alegre, (6)13: 1-48. described Hippopsis as follows: body extremely elongate, cylindrical and very narrow in stature; antennae very slender, much longer than the body, at least the first segments fringed below; scape very long and slender; eyes slightly coarsely faceted, rather slightly emarginate; frons trapezoidal; pronotum from slightly transverse to longer than wide, convex, without lateral tubercles; elytra extremely elongate, very narrow, parallel-sided, convex, slightly wider than pronotum; head not retractile [sic]; legs short, with femora slightly clavate, tibiae with dorsal sulcus, and tarsal claws divergent.

The separation between Hippopsis and Megacera Audinet-Serville, 1835 has always been problematic and questionable. Galileo et al. (2017b)Galileo, M.H.M.; Santos-Silva, A. & Wappes, J.E. 2017b. Two new species of Lamiinae, synonymies in Hemilophini, and corrections on the concept of four genera with transfers of three species (Coleoptera, Cerambycidae). Zootaxa, 3247(4): 445-460. questioned the previous concept of these two genera (Bates, 1866Bates, H.W. 1866. Contributions to an insect fauna of the Amazon Valley. Coleoptera: Longicornes. The Annals and Magazine of Natural History, Serie 3, 17: 1-42.; Breuning, 1962Breuning, S. 1962. Révision des Agapanthiini Muls. américains (Col., Cerambycidae). Pesquisas, Porto Alegre, (6)13: 1-48.; Martins & Galileo, 2006Martins, U.R. & Galileo, M.H.M. 2006. Gênero Hippopsis (Coleoptera, Cerambycidae, Lamiinae): chave para as espécies, sinonímia e descrição de espécies novas. Revista Brasileira de Entomologia, 50(4): 475-487.) and reported: “Provisionally, we are keeping them as different genera and using the combination of two characters to separate them: head behind eyes distinctly elongate (2 or 3 times longer than length of upper eye lobes), and typically with frons clearly oblique in Hippopsis; head behind eyes less elongate (usually about equal to length of upper eye lobe) and frons vertical in Megacera)”.

Here we describe a new species of Hippopsis from Napo Province, Ecuador. The type locality is found within a tropical mountain cloud forest with annual rainfall averages between 2,500 and 3,500 mm and the mean monthly temperatures ranging from 15 to 17℃. The forest consists of thick vegetation with tree trunks densely covered with epiphytes (Mariscal et al., 2022Mariscal, A.; Tigabu, M.; Savadogo, P. & Odén, P.C. 2022. Regeneration status and role of traditional ecological knowledge for cloud forest ecosystem restoration in Ecuador. Forests, 13(92). https://doi.org/10.3390/f13010092.
https://doi.org/10.3390/f13010092...
).

During the process of identification of the new species, we encountered an issue with the definition of Hippopsis quadrivittata Breuning, 1940 by Galileo & Martins (1988a)Galileo, M.H.M. & Martins, U.R. 1988a. Notas sobre Agapanthiini (Coleoptera, Cerambycidae, Lamiinae). IV. Hippopsis do grupo pradieri.

Gênero Hippopsis (Coleoptera, Cerambycidae, Lamiinae): chave para as espécies, sinonímia e descrição de espécies novas. Revista Brasileira de Entomologia, 50(4): 475-487.. Therefore, we are addressing this problem herein.

MATERIAL AND METHODS

Photographs were taken at MZSP with a Canon EOS TD Mark II camera and Canon MP-E 65 mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in “mm” using measuring ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope, also used in the study of the specimens. The terminology used herein for morphological structures follows Lawrence et al. (2010.)Lawrence, J.F.; Beutel, R.G, Leschen, R.A.B. & Ślipiński, A. 2010.

Dimensions (mm) (Holotype female/paratype female). Total length, 20.20/18.60; prothoracic length, 2.60/2.50; anterior prothoracic width, 2.30/2.25; posterior and maximum prothoracic width, 2.55/2.30; humeral width, 4.10/3.85; elytral length, 15.30/14.05.

Type material: Holotype female from ECUADOR, Napo: Cosanga, 2,100 m, on cut wood at night, 25.XI.2022, J. Vlasak leg. (MZSP). Paratype female, same data as holotype (JVCO).

Etymology: The specific epithet “sexlineata”, from Latin “sex” (six) and “lineata” (lined), refers to the six distinct yellow pubescent bands on the dorsal side of elytra.

Remarks: The new species, H. sexlineata sp. nov., fits in the key by Breuning (1962)Breuning, S. 1962. Révision des Agapanthiini Muls. américains (Col., Cerambycidae). Pesquisas, Porto Alegre, (6)13: 1-48. at the alternative of couplet “10” with H. quadrivittata Breuning, 1940 and following toward the alternative of couplet “11”. The alternative of couplet “10” has the first part very subjective: Disk of the pronotum distinctly transversely striate, leading to H. quadrivittata; disk of the pronotum not or slightly striate, leading to alternative of couplet “11”. However, in the second part, he provided a more reliable feature: abdomen with a longitudinal pubescent band centrally, leading to H. quadrivittata; abdomen without a longitudinal pubescent band centrally, leading the alternative of couplet “11”. As H. sexlineata sp. nov. has no central pubescent band on the abdominal ventrites, it cannot be confused with H. quadrivittata (Fig. 3L). In the alternative of couplet “11” H. sexlineata sp. nov. cannot be identified as H. assimilis Breuning, 1940 because the prothorax has six longitudinal pubescent bands (seven if considered the very narrow central pubescent band on the pronotum) (four in H. assimilis - five if considered the slightly distinct central pubescent band on the pronotum of some specimens), then following toward the alternative of couplet “12”, with H. truncatellaBates, 1866Bates, H.W. 1866. Contributions to an insect fauna of the Amazon Valley. Coleoptera: Longicornes. The Annals and Magazine of Natural History, Serie 3, 17: 1-42. and H. densepunctata Breuning, 1940. The feature used by Breuning (1962)Breuning, S. 1962. Révision des Agapanthiini Muls. américains (Col., Cerambycidae). Pesquisas, Porto Alegre, (6)13: 1-48. to separate these two species is very subjective: Elytra densely and slightly finely punctate, leading to H. truncatella; Elytra very densely and very finely punctate, leading to H. densepunctata. However, H. truncatella has the pronotum not transversely striate, not even slightly. Bates (1866)Bates, H.W. 1866. Contributions to an insect fauna of the Amazon Valley. Coleoptera: Longicornes. The Annals and Magazine of Natural History, Serie 3, 17: 1-42. did not report the presence of striation in H. truncatella and Galileo & Martins (1988b)Galileo, M.H.M. & Martins, U.R. 1988b. Notas sobre Agapanthiini (Coleoptera, Cerambycidae, Lamiinae). V. Revisão do gênero Hippopsis Lepeletier & A.-Serville, 1825. Revista Brasileira de Entomologia, 32(2): 199-207. affirmed that the pronotum is not striate. Therefore, H. sexlineata sp. nov. differs from H. truncatella by the pronotum transversely striate and by the prothorax distinctly shorter than distance between humeri (about as long as the distance between humeri in H. truncatella). The new species differs from H. densepunctata by the lower eye lobes distinctly shorter than twice genal length (according to Breuning, 1940bBreuning, S. 1940b. Novae species Cerambycidarum. X. Folia Zoologica et Hydrobiologica, 10: 407-437., more than twice genal length in H. densepunctata), pronotum transversely striate (only punctate in H. densepunctata), and outer angle of the elytra distinctly spiniform (not spiniform in H. densepunctata). Hippopsis sexlineata sp. nov. also differs from H. assimilis and H. quadrivittata by the dorsal surface of elytra with six longitudinal yellow pubescent bands (four in H. assimilis and H. quadrivittata); from H. truncatella by the antennomeres III-IV bicolorous (antennomeres III-IV unicolorous in H. truncatella); and from H. densepunctata by the elytra distinctly bispinose (strongly oblique with only the outer angle projected in H. densepunctata).

Revista Brasileira de Entomologia, 50(4): 475-487. leads H. sexlineata sp. nov. to the alternative of couplet “8”, with H. pradieri Guérin-Méneville, 1844 (Figs. 2C-2D) and H. macrophthalma Breuning, 1940 (Figs. 2A-2B). The new species differs from both especially by the truncate and bispinous elytral apex, while it has a long and single spiniform projection in H. pradieri and H. macrophthalma, similar to specimens of H. fractilinea (Fig. 3A-3K).

According to him, the innermost longitudinal yellow pubescent band on elytra is not distinct apically. The photograph of the holotype suggests that this pubescent band was grated. Breuning (1940a)Breuning, S. 1940a. Novae species Cerambycidarum. VIII. Folia Zoologica et Hydrobiologica, 10: 37-85. did not clearly report the shape of the elytral apex. He made it clear that there was a short spine on the sutural angle, but the shape of the elytral apex was not provided. In the key to species of Hippopsis by Breuning (1962)Breuning, S. 1962. Révision des Agapanthiini Muls. américains (Col., Cerambycidae). Pesquisas, Porto Alegre, (6)13: 1-48. this species was included in the alternative of couplet “8”, (translated): “Elytral sutural angle projected in spine”. Based on the photograph of the holotype (Fig. 3L), the elytral apex is distinctly transverse and concave, with outer and sutural angles spiniform.

Pesquisas, Porto Alegre, (6)13: 1-48.: 8) [redescription] separating H. biapicata from H. fractilinea is the relation between the length of lower eye lobe and the genae: twice the length of the genae in H. biapicata and less than twice the length of the genae in H. fractilinea. This is a secondary sexual feature, which invalidates the distinction between species. Furthermore, D.S. Napp (pers. comm.) examined the two holotypes [sic - syntypes of H. fractilinea] at the “Muséum National d’Histoire Naturelle”, Paris, and considered them as belonging to the same species. Hippopsis fractilinea and H. quadrivittata have elytral color pattern similar and are separated by the appearance of the apex of the elytra”. Still, according to Galileo & Martins (1988a)Galileo, M.H.M. & Martins, U.R. 1988a. Notas sobre Agapanthiini (Coleoptera, Cerambycidae, Lamiinae). IV. Hippopsis do grupo pradieri. Revista Brasileira de Entomologia, 32(2): 196-198., H. quadrivittata (translated): “The holotype [of H. quadrivittata] was not located by D.S. Napp (pers. comm.) at the “Muséum National d’Histoire Naturelle”, Paris”.

The holotype of H. quadrivittata was photographed in Paris by Jesus Santiago Moure and Gérard L. Tavakilian (Fig. 3L). Evidently, the specimens considered as being H. quadrivittata by Galileo & Martins (1988a)Galileo, M.H.M. & Martins, U.R. 1988a. Notas sobre Agapanthiini (Coleoptera, Cerambycidae, Lamiinae). IV. Hippopsis do grupo pradieri. Revista Brasileira de Entomologia, 32(2): 196-198. and Martins & Galileo (2006)Martins, U.R. & Galileo, M.H.M. 2006. Gênero Hippopsis (Coleoptera, Cerambycidae, Lamiinae): chave para as espécies, sinonímia e descrição de espécies novas. Revista Brasileira de Entomologia, 50(4): 475-487. are specimens of H. fractilinea. The elytral apex in H. fractilinea is very variable (Figs. 3A-3K, 3M). Also, the width of the longitudinal yellow pubescent bands, vertex, pronotum, and elytra, are somewhat variable, and not related to the geographical distribution. The specimens in Figures 3A-3G were identified by Ubirajara R. Martins de Souza as H. fractilinea at MZSP collection and the specimens in Figures 3H-3K as H. quadrivittata.

Currently, H. fractilinea is known from Ecuador, Brazil (Amazonas, Pará, Rondônia), Peru, and Bolivia (Cochabamba, Santa Cruz), while H. quadrivittata from Colombia, Ecuador, and French Guiana (Monné, 2023Monné, M.A. 2023.
