    International audienceAim: Locally abundant species are usually widespread, and this pattern has been related to properties of the niches and traits of species. However, such explanations fail to account for the potential of traits to determine species niches and often overlook statistical artefacts. Here, we examine how trait distinctiveness determines the abilities of species to exploit either common habitats (niche position) or a range of habitats (niche breadth) and how niche position and breadth, in turn, affect abundance and occupancy. We also examine how statistical artefacts moderate these relationships. Location: Sixteen sites in the Neotropics. Time period 1993–2014. Major taxa studied Aquatic invertebrates from tank bromeliads. Methods: We measured the environmental niche position and breadth of each species and calculated its trait distinctiveness as the average trait difference from all other species at each site. Then, we used a combination of structural equation models and a meta-analytical approach to test trait–niche relationships and a null model to control for statistical artefacts. Results: The trait distinctiveness of each species was unrelated to its niche properties, abundance and occupancy. In contrast, niche position was the main predictor of abundance and occupancy; species that used the most common environmental conditions found across bromeliads were locally abundant and widespread. Contributions of niche breadth to such patterns were attributable to statistical artefacts, indicating that effects of niche breadth might have been overestimated in previous studies. Main conclusions: Our study reveals the generality of niche position in explaining one of the most common ecological patterns. The robustness of this result is underscored by the geographical extent of our study and our control of statistical artefacts. We call for a similar examination across other systems, which is an essential task to understand the drivers of commonness across the tree of life

    Heterachthes caceresae sp. nov. urn:lsid:zoobank.org:act: BED20ABD-5CD7-4C08-A1B3-A729208E0830 Figs 1–6 Diagnosis Heterachthes caceresae sp. nov. (Figs 1–6) is similar to H. viticulus Martins, 1970 (Figs 7–10), but differs as follows: antennae dark brown; distance between antennal tubercles less than half of basal width of scape; prothorax in male proportionally longer (Fig. 1); pronotum not transversely rugose (Fig. 5). In H. viticulus, antennae are reddish, distance between antennal tubercles distinctly greater than half of basal width of scape, prothorax in male proportionally shorter (Fig. 10), and pronotum is distinctly transversely rugose in both sexes (Figs 7–9).

    Longhorned woodboring beetles (Coleoptera, Cerambycidae) from Cusuco National Park, Honduras: new species, new records, and revalidation

    An ongoing study of the longhorned beetle fauna in the cloud forests of Cusuco National Park revealed multiple additions to the Honduran fauna. Four new species are described: Heterachthes caceresae sp. nov. (Cerambycinae, Neoibidionini), Oreodera kawasae sp. nov. (Lamiinae, Acrocinini), Phrynidius guifarroi sp. nov. (Lamiinae, Apomecynini), and Strangalia lunai sp. nov. (Lepturinae, Lepturini). Additionally, Lagocheirus parvulus Casey, 1913 (Lamiinae, Acanthocinini) is revalidated as Lagocheirus araneiformis parvulus Casey, 1913 (Lagochirus [sic]). We recorded Arixiuna varians (Bates, 1881) (Lamiinae, Hemilophini) for the first time for Honduras. These findings confirm how poorly the invertebrate biodiversity of cloud forests is documented and hints at the large number of species we are losing with the ongoing deforestation

Material examined HONDURAS ‱ 1 ♂; CortĂ©s, Cusuco National Park, Base camp; 10 Jun. 2017; ED. Leg.; RBINS. New formal country record Remarks Bates (1881a) described H. varians based on a series of males and females from Mexico and Guatemala, and reported on the elytral color (translated from Latin): “Elytra entirely fulvous, or posteriorly black and fulvous anteriorly, or with the humerus fulvous [remaining surface black].” Martins & Galileo (1992), erected Arixiuna, and separated it from Hemilophus Audinet-Serville, 1835 by the absence of whitish pubescence on sides of the elytra (present in Hemilophus), and from Cuicirama Martins & Galileo, 1992 by the non orthogonal humerus (orthogonal in Cuicirama) (Martins & Galileo 1992). Later, Galileo & Martins (2005) described Hemilocrinitus and separated it from Arixiuna especially by the antennal tubercles close to each other (distant in Arixiuna). Hovore (2006) reported the geographical distribution of Arixiuna varians as “eMEX (VC), GUA-CR”, meaning that the geographical distribution of the species is from east Mexico (Veracruz), and from Guatemala to Costa Rica. Swift et al. (2010) reported that the species occurs from Mexico (Veracruz) to Costa Rica (Heredia). MonnĂ© (2021) reported the species as present in Mexico (Veracruz), Guatemala, and Costa Rica. We think that the report by MonnĂ© is better because, although it is very probable that the species also occurs in Honduras and Nicaragua, there is no evidence.Published as part of Santos-Silva, Antonio, Roie, Martijn Van & JocquĂ©, Merlijn, 2021, Longhorned woodboring beetles (Coleoptera, Cerambycidae) from Cusuco National Park, Honduras: new species, new records, and revalidation, pp. 37-61 in European Journal of Taxonomy 764 on page 52, DOI: 10.5852/ejt.2021.764.1469, http://zenodo.org/record/523606

Males of the new species differ from those of S. beltii, S. bivittata, S. elegans, S. picticornis, S. saltator, and S. veracruzana by the pronotum lacking two longitudinal dark bands (present in all these species); from S. doyeni by the pronotum mostly black (orange in S. doyeni), and by the sides of the abdominal ventrite V not strongly flap-shaped (noticeably flap-shaped in S. doyeni); from S. eickworti by the distal antennomeres not distinctly yellowish (distinctly yellowish in S. eickworti), and profemora bicolorous (unicolorous in S. eickworti); from S. emaciata by last antennomeres not distinctly yellowish (distinctly yellowish in S. emaciata), and maxillary palpomere IV not widened apically (widely expanded in S. emaciata); from S. instabilis by the distal antennomeres not distinctly yellowish (distinctly yellowish in S. instabilis), and sides of the abdominal ventrite V not strongly flap-shaped (noticeably flap-shaped in S. instabilis); from S. occidentalis by the sides of the abdominal ventrite V not strongly flap-shaped (noticeably flap-shaped in S. occidentalis); from S. pectoralis by the elytra proportionally longer (shorter in S. pectoralis); from S. sexocellata by the antennae only surpassing middle of elytra (reaching elytral apex in S. sexocellata). Males of S. sallaei are unknown. However, based on other similar species, the pronotum probably has two dark longitudinal bands and the antennae are distinctly bicolorous.

Lagocheirus stroheckeri granulatus Dillon, 1956: 139. Material examined HONDURAS ‱ 2 ♀♀; CortĂ©s, Cusuco National Park, Santa Thomas, transect 2; 20 Jul. 2015; beginning of night, ‘ disturbed forest’; L. Geeraert and M. JocquĂ© leg.; RBINS. Remarks Voet (1778?) described Cerambyx ypsilon (Fig. 11) from “ America septentrionali”.According to Santos- Silva et al. (2010) on Polyrhaphis spinosa (Drury, 1773) (translated from Portuguese): “
it is worth noting that this work was successively added to new parts from 1766 onward and, contrary to what appears in almost all the catalogs on Cerambycidae, many species are before 1778 and were already published in 1776 (Beckmann 1776). Sherborn (1902) was probably the first to report that Voet’s work (op. cit.) did not follow the binominal system 
 Anyway, in relation to Polyrhaphis spinosa, the name used by Voet (op. cit.), only appeared after 1776 because, according to Beckmann (op. cit.), in that year the work only included 14 species in Cerambyx and eight pages (Cerambyx horridus was published on page 15, as species number 59). With the death of Johannes Eusebius Voet, in 1778, the work was unfinished, but in 1796 volume II, in which Cerambyx was addressed, already had 24 pages and 24 prints (Dryander & Banks 1796). As the work did not undergo additions between 1778 (Voet’s passing) and 1804 [British Museum (Natural History) 1915], Voet had undoubtedly already included Cerambyx horridus [= Polyrhaphis spinosa] in his work.” The same reasoning can be used regarding Cerambyx ypsilon, which was published on page 11 (Latin part). Nevertheless, the names published by Voet (1766 – 1806) cannot be considered as nomenclaturally available, as has been indicated by some authors, for example, Alonso-Zarazaga & Lyal (1999), Santos-Silva et al. (2010), and Krell (2012). Schönherr (1817) synonymized Cerambyx ypsilon with Cerambyx araneiformis Linnaeus, 1767. Dillon (1956) described Lagocheirus stroheckeri granulatus based on males and females from the USA (Texas), and Linsley & Chemsak (1995) synonymized it with L. araneiformis ypsilon. Dillon (1957) considered C. ypsilon as a subspecies of Lagocheirus araneiformis, without comment about the synonymy proposed by Schönherr (1817), which is also present in Aurivillius (1922), and Blackwelder (1946). In the same work, Dillon (1957) synonymized L. parvulus with L. araneiformis ypsilon, which was described by Casey (1913) based on a single male from Panama. Currently, the species is known as Lagocheirus araneiformis ypsilon, with L. parvulus, and L. stroheckeri granulatus as junior synonyms. It is not possible to be sure whether Cerambyx ypsilon is really synonymous with Lagocheirus parvulus Casey, 1913 (generic name published as Lagochirus, attributed to Erichson (1847), but Lagocheirus is by Dejean (1835)). This is because the short description and drawing in Voet (1778?) do not allow confirmation. Unfortunately, Voet’s collection is probably lost; according to Santos-Silva et al. (2010) discussing Polyrhaphis armiger (Schönherr, 1817) (translated from Portuguese): “According to British Museum (Natural History) (1915), the stock from Johannes Eusebius Voet was acquired by Bakhuysen in 1804. We do not know whether Voet’s insect collection was part of the material acquired by G. Bakhuysen, but according to Reichard (1827), this insect collection remained in La Haye: “La Haye. Cette ville, qui n’a ni murs ni portes, est entourĂ©e d’un large fossĂ© sur lequel on a pratiquĂ© des ponts-levis. Elle surpasse nĂ©anmoins plusieurs villes cĂ©lĂšbres par la magnificence de ses bĂątimens et ses autres ornemens. CuriositĂ©s: 
 les cabinets d’insectes de MM. Voet et Meuschen, le cabinet de conquillages de M. Lyonnet”
 [The Hague. This city, which has neither walls nor gates, is surrounded by a wide moat over which drawbridges have been made. It nevertheless surpasses several famous cities by the magnificence of its buildings and its other ornaments. Curiosities: 
 the insect cabinets of Voet and Meuschen, the cabinet of shells of Mr. Lyonnet 
].” However, it is not within the scope of this work to verify previously proposed synonymies, but only to solve the problem related to the correct name of the species/ subspecies. As Lagocheirus parvulus is the oldest available name, it is used instead of “ ypsilon ”. Accordingly, the name of the subspecies is L. araneiformis parvulus. The specimens from Honduras examined by us (Fig. 12) agree well with several specimens identified as L. araneiformis ypsilon in MZSP collection. However, comparing the original description of L. stroheckeri Dillon, 1956 (currently, L. araneiformis stroheckeri), as well as photographs of the holotype and allotype of this species with the specimens usually identified as L. a. ypsilon, the only reliable difference we have found is the more angulate humerus in L. stroheckeri. This suggests that the current subspecies of L. araneiformis need a full revision because at least part of them may be just variations of the same taxon (especially L. stroheckeri, which is probably synonymous with L. parvulus).Published as part of Santos-Silva, Antonio, Roie, Martijn Van & JocquĂ©, Merlijn, 2021, Longhorned woodboring beetles (Coleoptera, Cerambycidae) from Cusuco National Park, Honduras: new species, new records, and revalidation, pp. 37-61 in European Journal of Taxonomy 764 on pages 42-43, DOI: 10.5852/ejt.2021.764.1469, http://zenodo.org/record/523606
