The type series is the only record for this species that we have encountered in our studies, except for: one female labeled “ Mexico, Gro, Taxco, 25 June, 1970, Peter M. Jump” (OSUC); one male labeled “ Mex. Puebla, Acatlan, 45 mi. n., VII- 30-63, J. Doyen” (CISC); 1 female labeled “ Mex, Puebla, 8 mi. s. of Izúcar de Matamoros, XII- 10-1948, E. S. Ross” (CASC); and 1 female labeled “ México, Michoacán, S. Jose Purúa, 4800 ’, VII- 27-1955, G. H. Dieke” (OSUC). These are not designated as paratypes, but appear to be conspecific. Variation. Except for size and slight difference in elytral punctures, there is little variation in the type series and other specimens examined. Females: Length: 18–20 mm, width: 8.5–11 mm. Males: 18.5–22 mm, width: 7.8–9 mm. Etymology. The name, a noun in apposition, is derived from Latin (curvi=bent; dens=tooth) in reference to the downcurved profemoral tooth in the male. Ecology and Phenology. Specimens were collected in Quilamula, a small community located in the state of Morelos, Mexico, that occurs in a marginal zone of the Sierra de Huautla Biosphere Reserve. Primary vegetation in the site corresponds to dry tropical forest, and is characterized by a marked seasonality. In general, the rainy season occurs from June to September, and the dry season from October to May (Dorado et al., 2005). The habitat at the type locality of Eleodes curvidens n.sp. is relatively well preserved and has extensive tree cover. Cattle were rarely seen there. The dominant tree species is Lysiloma divaricatum (Jacq.) J. F. Macbr., and the dominant herbaceous species is Oplismenus burmannii (Retz.) P. Beauv. Unbaited pitfall traps were used to collect specimens. Sixteen traps were set the third week of each month from December, 2006 to November, 2007. They were arranged in 4 columns by 4 rows separated by 11.5 m in two sites, one better preserved than the other (i.e. with differences in plant communities such asspecies composition, and individual density). Eleodes curvidens was the dominant tenebrionid species present in the traps. Twenty five individuals were collected (three more were collected by hand in April). The species was present mainly during the dry season from December to April and in November. A sympatric species, Eleodes ponderosus Champion, was the second most abundant species (17 individuals) and was also present during the dry season: December, January, March, April and November and in two months of the rainy season: August and October. It is remarkable that both species were present mainly during the dry season. Food abundance at this time of year could be the reason. In dry tropical forests, the peak of litter production (composed of leaves, seeds, and fruits) takes place during the dry season, as well as flowering and fruiting episodes, and seed dispersion with different intensities (Bullock and Solis-Magallanes, 1990; Lawrence, 2005). At least in more arid environments such as grasslands and shrubland, Eleodes species feed on plant detritus and predate on seeds (Crawford, 1981; Thompson, 1985; Wiens et al., 1995). It is noteworthy that both species were collected only in the more preserved site and were absent in the site with the poorer plant structure where cattle are kept, and the dominant tree is the secondary vegetation species Acacia cochliacantha Humb. & Bonpl. ex Willd. A lack of shelters, such as pieces of bark, and food may explain this pattern. Doyen and Tschinkel (1974) for example, reported that some species of Eleodes were found with more frequency under decomposing trunks than in other kinds of substrates such as herb cover, pine needles or bare soil.Published as part of Triplehorn, Charles A. & Ruiz, Paulina Cifuentes, 2011, A new species of Eleodes (Eleodes) from Mexico, with ecological and phenological notes (Coleoptera: Tenebrionidae), pp. 66-68 in Zootaxa 2937 on pages 66-67, DOI: 10.5281/zenodo.20237

Biodiversidad de Tenebrionidae (Insecta: Coleoptera) en México

ResumenA partir de la consulta de la Colección Nacional de Insectos del Instituto de Biología, UNAM, de bases de datos y bibliografía, se actualiza la información sobre la diversidad de Tenebrionidae en México y su estudio. Asimismo, se aporta información sobre la distribución estatal de las especies. Con base en estos datos, se detecta que el trabajo taxonómico y el trabajo de campo son aún insuficientes y se ubican los estados que deberían muestrearse en un futuro, así como algunos taxones que deberían revisarse.AbstractAfter consulting the National Insect Collection holdings of the Instituto de Biología, UNAM, databases and literature, information about Mexican Tenebrionidae diversity and its study in Mexico is updated. Information about the species state distribution is presented as well. Based on these data, we detected that taxonomic and exploratory field work is still insufficient, so states where future sampling should be done are proposed as well as several taxa that should be revised

A preliminary phylogenetic analysis of the New World Helopini (Coleoptera, Tenebrionidae, Tenebrioninae) indicates the need for profound rearrangements of the classification

Helopini is a diverse tribe in the subfamily Tenebrioninae with a worldwide distribution. The New World helopine species have not been reviewed recently and several doubts emerge regarding their generic assignment as well as the naturalness of the tribe and subordinate taxa. To assess these questions, a preliminary cladistic analysis was conducted with emphasis on sampling the genera distributed in the New World, but including representatives from other regions. The parsimony analysis includes 30 ingroup species from America, Europe and Asia of the subtribes Helopina and Cylindrinotina, plus three outgroups, and 67 morphological characters. Construction of the matrix resulted in the discovery of morphological character states not previously reported for the tribe, particularly from the genitalia of New World species. A consensus of the 12 most parsimonious trees supports the monophyly of the tribe based on a unique combination of characters, including one synapomorphy. None of the subtribes or the genera of the New World represented by more than one species (Helops Fabricius, Nautes Pascoe and Tarpela Bates) were recovered as monophyletic. Helopina was recovered as paraphyletic in relation to Cylindrinotina. One Nearctic species of Helops and one Palearctic species of Tarpela (subtribe Helopina) were more closely related to species of Cylindrinotina. A relatively derived clade, mainly composed by Neotropical species, was found; it includes seven species of Tarpela, seven species of Nautes, and three species of Helops, two Nearctic and one Neotropical. Our results reveal the need to deeply re-evaluate the current classification of the tribe and subordinated taxa, but a broader taxon sampling and further character exploration is needed in order to fully recognize monophyletic groups at different taxonomic levels (from subtribes to genera)

First report of the genus Cladotoma Westwood, 1837 (Coleoptera, Ptilodactylidae, Cladotominae) in Mexico

Cladotoma ovalis Westwood, 1837 is record for the first time in Mexico, in the states of Jalisco and Chiapas. Illustrations, distribution map and a diagnosis for the genus and for C. ovalis are herein presented. A checklist of Ptilodactylidae species in Mexico and an identification key for Mexican genera is also presented

Life cycle and description of the immature stages of a terrestrial firefly endemic to Mexico: Photinus extensus Gorham (Coleoptera, Lampyridae)

The life cycle, morphology, and bionomy of Photinus extensus Gorham, 1881, an endemic species of Mexico, are described. Redescriptions of adults (male and female) are also presented. Larvae were reared to the adult stage from eggs laid by females collected at the El Pedregal de San Ángel Ecological Reserve, south of Mexico City. The activity period of adults of P. extensus begins at the end of July and finishes by the end of August. Females lay between 3 and 198 eggs. Larvae hatch from the eggs after a period of 11 to 71 days, undergo 6 larval instars and a pupal stage in an annual cycle. Morphological characters of the sixth larval instar of P. extensus are compared with those of several other genera assigned to the tribe Photinini. Knowledge of the natural history of firefly larvae is relevant since most species do not feed as adults and therefore depend on resources acquired during the larval stage
