A new genus and species of Callipogonini, description of the male of Strongylaspis boliviana Monne & Santos-Silva, 2003, and a new distributional record for Chorenta reticulata (Coleoptera, Cerambycidae)

Seticeros gen. n. and Seticeros tunupai sp. n. of the tribe Callipogonini (Coleoptera, Cerambycidae) from Yungas, Bolivia and the male of Strongylaspis boliviana Monné & Santos-Silva, 2003 are described and illustrated. Chorenta aquilus (Th omson, 1865) is transferred to Seticeros gen. n. A new distributional record for Chorenta reticulata (Dalman, 1817) is given.


Introduction
Th e Bolivian Yungas, a mountain forest area mainly located in the departments of La Paz and Cochabamba, is one of the world's biodiversity hotspots and is characterized by high levels of endemism (Barthlott and Winiger 1998).Wappes et al. (2006) cited records for six species of Prioninae for the departments of La Paz and Cochabamba and 15 for the department of Santa Cruz, which is mainly covered by lowland forests.Nine species were cited with country record only.Of the listed prionine species from the department of La Paz, Strongylaspis boliviana Monné & Santos-Silva, 2003 is the only known endemic representative, while the female holotype is the only known specimen (Monné and Santos-Silva 2003).Wappes et al. (2006) affi rm that the higher level of knowledge about the fauna of the department of Santa Cruz -as a result of the collection bias -is one of the reasons for the diff erence found between the Cerambycidae diversity in Santa Cruz and the remaining departments.
Th is paper contributes to the knowledge of the cerambycid diversity of the Bolivian Yungas, while it proposes a new species of the tribe Callipogonini possibly endemic to this area.
A new genus for the newly described species is proposed and, based on the similarities from important characteristics, Chorenta aquilus (Th omson, 1865) from Colombia is also transferred to the new genus.
Th e male of Strongylaspis boliviana is described and a new distributional record for Chorenta reticulata (Dalman, 1817) for the Bolivian Yungas is given.Male.Body weakly depressed; head (without mandibles) + prothorax smaller than 2.0 times to almost 2.5 times of the elytral length.Head (Figs 1,3,6,8) proportionally large and wide; punctation of dorsal surface (Figs 6, 8) consistently coarse and deep or confl uent.Eyes large; upper ocular lobe slightly narrower than lower ocular lobe; distance between upper ocular lobes (Figs 1, 3) little larger than 2.0 times the width of antennomere III at basal third; distance between lower ocular lobes (Figs 6,8) equal to approximately 1.5 times distance between posterior tentorial pits.Ocular carina (Figs 1, 2, 3) indistinct or absent.Clypeus wide, strongly depressed centrally, and strongly oblique towards labrum.Labrum horizontal, narrow, concave frontally, and distinctly lower than base of clypeus.Hypostomal area sculptured; pilosity moderately long, sparse; hypostomal carina narrow and slightly distinct.Galea surpassing base of second segment of maxillary palps.Mandibles (Figs 1,2,3,6,8) longer or approximately as long as half of length of head; inner surface with sparse hairs; lowerinner margin with single, somewhat rounded and wide tooth, near inner apical tooth.Antennae (Figs 1, 2) reach apical fourth of elytra; scape reaching or just surpassing posterior edge of eye; ventral surface of antennal segments (Fig. 2) with somewhat long and abundant hairs, gradually shorter and sparser towards segment XI.

Apolinar col.(MZSP).We also examined photos of the fi ve syntypes of this species.
Geographical distribution: Colombia and Bolivia.
Comments.Seticeros gen.n. diff ers from Chorenta Gistel, 1848 as follows: ventral surface of antennal segments (Fig. 2) with somewhat long and abundant hairs, mainly in segments III-VI, more conspicuous in female; hypostomal area of male without abundant pilosity (Figs 6,8), and in female more distinctly punctate (Figs 7, 9), metasternum and metepisternum with abundant pilosity.In Chorenta the antennal segments are glabrous in both sexes; the hypostomal area of the male (Figs 10, 12) has somewhat long and very abundant pilosity, in the female less punctate (Figs 11,13) and the metasternum and metepisternum are glabrous.
It diff ers from Hephialtes Th omson, 1864 as follows: labrum narrow and placed distinctly lower than the base of clypeus; antennal segments, metasternum and metepisterna as described in the comparison with Chorenta; protibia not distinctly enlarged towards apex; elytral carina very distinct.In Hephialtes the labrum is wide and coplanar with the clypeus, the antennal segments, metasternum, and metepisterna are glabrous, the protibia is distinctly enlarged towards apex, and the elytral carinae is not strongly marked.
From Stictosomus Audinet-Serville, 1832 it diff ers in the following characters: mandibles short in both sexes (approximately as long as the half of the head); antennal segments, metasternum and metepisterna as described in the comparison with Chorenta; profemurs rugose; metatarsomere V at most as long as the metatarsomeres I-II together.In Stictosomus the mandibles are distinctly longer than the half of the length of head (mainly in the male), the antennal segments, metasternum, and metepisterna are glabrous, in the male the third antennal segment is about as large as antennal segments IV, V, and VI together; the profemurs are smooth, and tarsomere V in all tarsi is longer than I-II together.

Seticeros tunupai sp. n.
urn:lsid:zoobank.org:act:B7D31BDA-279A-4259-B760-123AA98F1511Figs 1-5 Etymology.Named after Tunupa, a god of the Aymara tribe, which is the largest group of native people living in the Yungas area.Tunupa is believed to be the creator of the Altiplano.
Hypostomal area fi nely and densely punctate, with long light-brown hair, pilosity only visible from lateral view (Fig. 2).Antennae (Figs 1, 2) reaching apical fourth of elytra; scape reaching posterior edge of eye; third antennal segment as long as segments IV-V together; ventral surface of antennal segments with somewhat long and abundant light-brown hairs, gradually shorter and sparser towards segment XI.
Legs robust.Profemur rugose; ventral surface of pro-and mesofemura with longitudinal grooves.Dorsal surface of protibia with depression gradually deeper towards the tibial-femur joint.Tibia and tarsi medial with short light-brown hairs.
Female (Fig. 4).Size 38-42 mm.Coloration of the elytra uniformly brown, pronotum dark brown, or as in elytra.Length of elytra 2.8-2.9 times as long as length of head (without mandibles) and prothorax.Size of mandibles and legs smaller than in male.

Comments: Seticeros tunupai sp.n. diff ers from Seticeros aquilus (Th omson, 1865) as follows: hypostomal area less coarsely punctate, more pilose.Pronotum in S. aquilus about 1.7 times as wide as long, anterior and lateral angles rounded and not clearly distinct, posterior angles without spine.Protuberances in central area of pronotum in S. aquilus without impressions, median elytral ridge convergent with the inner.Apical spine of elytra in S. tunupai sp.n. considerably longer than in S. aquilus.
Sternites fi nely, abundantly punctate; pilosity of sternites I-IV abundant laterally, sparser medially; sternite V strongly emarginate at apex, and with pilosity sub-equally distributed throughout.Profemora and protibiae scabrous, with coarse, small, spines on ventral face; mesofemora and mesotibiae less scabrous, and with spines of ventral face smaller and sparser; metafemora not scabrous, abundantly punctate on ventral face, sub-smooth in remaining areas, without spines on ventral face; metatibiae distinctly less scabrous than pro-and meso-tibiae, and with spines of ventral face less distinct and sparser.Metatarsomere I as long as II-III together.
Comments.Monné & Santos-Silva (2003) described Strongylaspis boliviana based on a single female from Nor Yungas (Bolivia).Th e specimen mentioned above is the fi rst collected after the original description.Th e male can be included in the key presented by Monné & Santos-Silva (2003) together with the female.
Despite the absence of specimens in southeastern Brazil and middle-eastern Argentina, the specimens collected in Bolivia are consistent with the specimens examined by us (more than 100 specimens from Brazil).Material examined.BOLIVIA: 1 ♂, Department of La Paz, Nor Yungas, street from Caranavi to Coroico, 1600-1800 m, XI.2009 (NDC); 1 ♂, 1 ♀, same data (RPC).
