Members of the genus Centris Fabricius (Hymenoptera: Apoidea: Anthophila) constitute a significant component of the Neotropical (including insular) bee fauna, exhibiting high species richness, a moderate to large body size, and extensive interactions with various important plant groups. Females of most species possess specialized morphology adapted for collecting oils from flowers. This study documents the presence of the genus in Cuba, recognizing six species: C. aethiops Cresson, C. cornuta Cresson, C. fulviventris Cresson, C. poecila Lepeletier, C. taina Genaro and Breto new species, and C. tarsata F. Smith. Detailed information is provided for each species, encompassing a diagnosis, natural history, floral associations, seasonal occurrence, and distribution. Centris taina new species is described from Cuba, based on both sexes, which were previously misidentified as C. versicolor (Fabr.) for females and C. fasciatus F. Smith for males due to sexual dimorphism. Centris tarsata is reported as a new national record for Cuba, possibly introduced by humans from South America and now established and widely distributed across the entire island. A key to differentiate the Cuban species of Centris is presented.

This contribution adds data to the conservation and distribution of Histeridae species (Coleoptera) in the Neotropical region through a survey of Brazil’s South region. More specifically, it provides: i) a list of local Histeridae species; ii) a list of species that are inside Conservation Units in southern Brazil; iii) biotic (biome, ecoregion and associations/affinities) and abiotic information (altitude and month of occurrence) for each species. In total, 66 genera and 164 histerid beetle species were recorded, distributed in seven subfamilies and 11 tribes. Among these, one genus and three species are new records for the region. Fifty percent of the species are known from a single geographic record. The Atlantic Forest is the richest biome in the South, in terms of number of species, and the Alto Paraná Atlantic forest is the richest ecoregion. Carcinops (s. str.) troglodytes (Paykull), Euspilotus (Hesperosaprinus) azureus (Sahlberg) and Omalodes (s. str.) angulatus (Fabricius) were recorded every month of the survey. Species’ richness was higher in October, December and January. Of the species recorded, 45 (27% of the total) are legally protected by Conservation Units in southern Brazil. Twenty-seven percent of the species recorded are associated with live animals. Collectively, the data presented here is a contribution to the taxonomic catalog of the Brazilian fauna.

A new species of Microphotina Beier, 1935 (Mantodea: Photinaidae: Microphotinini), Microphotina cristalino sp. nov., is described from Mato Grosso, Brazil based on two male specimens. The new species extended the distribution of Microphotina to the southern limits of the Amazon rainforest, in the Cerrado-Amazônia ecotone. A synthesis of the taxonomy, systematics, natural history, and geographic distribution of Microphotina spp. is provided, along with an updated dichotomous key to species. The hypothesis that Microphotina represents a canopy-dwelling lineage is formulated. The role of praying mantises as flagship species for insect and Amazon conservation is briefly discussed.
The New World genus Axina Kirby (Coleoptera: Cleridae) is revised for the first time. Thirty-two new species are described: Axina acutipennis, A. adelosa, A. atmis, A. bahia, A. bella, A. brunnea, A. chiasta, A. furcula, A. heveli, A. ignota, A. klisis, A. latilinea, A. lobispinula, A. luzia, A. macilenta, A. megaspina, A.minas, A. ochra, A. oligocheia, A. ordinis, A. orcastomata, A. pallidioccabus, A. phallospina, A. piperata, A. pollex, A. polycaula, A. rio, A. schenklingi, A. spina, A. trinalis, A. villa, and A. vista. The 19 previously described species are: Axina analis Kirby, A. apicalis Pic, A. basalis Schenkling, A. bifasciata (Chevrolat), A. centrimaculata Schenkling, A. conspicua Schenkling, A. diversesignata Pic, A. equestris (Schenkling), A. fasciata Kirsch, A. fortipes Pic, A. lateralis Pic, A. longevittata Pic, A. munda Schenkling, A. nigrifrons Schenkling, A.parcepunctata Schenkling, A. picta Schenkling, A. plagiata Schenkling, A. proxima (Chevrolat), and A. sexmaculata Spinola. Two species Priocera equestris Schenkling and Priocera proxima Chevrolat, are transferred into the genus Axina becoming new combinations: Axina equestris (Schenkling) and Axina proxima (Chevrolat). Two names, Priocera podagrica Schenkling, 1900, and P. podagrica variety pygmaea Schenkling, 1902, are new synonymies of Priocera proxima Chevrolat, 1876. Lectotypes are here designated for nine species: Axina basalis Schenkling, 1900; Axina centrimaculata Schenkling, 1900; Axina conspicua Schenkling, 1900; Axina diversesignata Pic, 1946; Axina munda Schenkling, 1900; Axina nigrifrons Schenkling, 1906; Axina parcepunctata Schenkling, 1900; Axina picta Schenkling, 1907; and Axina plagiata Schenkling, 1900. It is proposed that Axina species are predators of lignicolous insects, particularly bark beetles. The species of Axina can be classified into eight species groups and a theory of their phylogenetic relationships is proposed via WINCLADA in conjunction with NONA. Of the 51 species that now comprise Axina, only one traversed the Panamanian portal before the Colombian Andes reached their modern altitudes. This work includes a generic-level morphological analysis, brief treatise of natural history, key to species, comments about Axinazoogeography, and hypotheses of species-group phylogeny.
Host flower records for 111 species of Cerambycinae, collected from 40 plant species (21 families) in three Bolivian Departments during the period 2002–2011 are presented for the following tribes: Basipterini, Callichromatini, Clytini, Compsocerini, Eburiini, Ectenessini, Heteropsini, Hexoplonini, Molorchini, Oxycoleini, Pteroplatini, Rhopalophorini, Tillomorphini, and Trachyderini. The importance of anthophilous cerambycids as pollinators, their behavior, and methods used for collecting them are presented, and some preliminary comparisons between the tropical fauna in the north and the temperate fauna in the Chaco forests of the south are outlined.
A new species of praying mantis, Vates phoenix sp. nov. (Mantidae, Vatinae), is described from localities within Rio de Janeiro and São Paulo states, Brazil. This is the first record of Vates from the Atlantic Rainforest biome. The new species is unique among its congeners in having, among other features, strongly reduced cuticular projections above the lateral ocelli, structures otherwise well developed and produced in all other species of Vates. Remarks on the natural history and biogeography of Vates, in relation to this new finding, are further discussed.
Descriptions and illustrations of the fi fth instar and prepupal larval stages of Stethon pectorosus LeConte, 1866 (Coleoptera: Eucnemidae: Eucneminae: Mesogenini) are provided. These are the fi rst larval descriptions for the genus Stethon LeConte within the subfamily Eucneminae in the Nearctic region. Biological information is provided and comparison with larval morphology of other Eucnemidae is briefl y discussed.
