Plumolepilius Barrios-Izás & Anderson, 2016 is a leaf litter weevil genus that inhabits montane broadleaf forests from southern Mexico to northern Panama. The genus consists of 27 species, 22 distributed in the Chiapas Highlands province (Mexican Transition Zone) and 5 found in the Pacific dominion (Neotropical region) in Costa Rica and Panamá. Here, we analyze the phylogenetic relationships of the species of Plumolepilius based on 20 external body characters and 9 characters from the genitalia. The first dichotomy of the cladogram separates two species from the Pacific dominion from the remaining species of Plumolepilius from the Chiapas Highlands province and three species restricted to the Pacific dominion. We hypothesize that redundant distributions in the taxon-area cladogram of the genus may be due to dispersal events, probably during the Pleistocene glaciations.

Abstract The genus Boiga includes 35, primarily arboreal snake species distributed from the Middle East to Australia and many islands in the western Pacific, with particularly high species diversity in South-East Asia. Despite including the iconic mangrove snakes (Boiga dendrophila complex) and the brown tree snake (Boiga irregularis; infamous for avian extinctions on small islands of the Pacific), species-level phylogenetic relationships and the biogeographic history of this ecologically and morphologically distinct clade are poorly understood. In this study, we sequenced mitochondrial and nuclear DNA for 24 Boiga species and used these data to estimate a robust phylogenetic inference, in order to (1) test the hypothesis that Boiga is monophyletic, (2) evaluate the validity of current species-level taxonomy and (3) examine whether geographic range evolution in Boiga is consistent with expectations concerning dispersal and colonization of vertebrates between continents and islands. Our results support the prevailing view that most dispersal events are downstream – from continents to oceanic islands – but we also identify a role for upstream dispersal from oceanic islands to continents. Additionally, the novel phylogeny of Boiga presented here is informative for updating species-level taxonomy within the genus.

The genus Oosternum Sharp, 1882 is divided into ten species groups based on external adult characters. An identification key to the species groups and a table of diagnostic characters as well as many charater state illustrations for each group are provided. Representatives of the newly defined O. aequinoctiale species group are revised. Six species of this group are recognized, all occurring in the Neotropical region: Oosternum acutheca sp.n. (Honduras, Costa Rica, Nicaragua), O. aequinoctiale (Motschulsky, 1855) (Bolivia, Colombia, Costa Rica, Ecuador, Mexico, Panama, Peru, Venezuela), O. attenuatum sp. n. (Panama, Colombia, Ecuador), O. gibbicolle sp. n. (Ecuador, Panama), O. holosericeum sp. n. (Argentina), and O. latum sp. n. (Lesser Antilles: St. Vincent Island). A key to the species and drawings or SEM photographs of diagnostic characters are provided.

In this work, I revise a group of thirteen species in a natural assemblage of Calligrapha Chevrolat previously shown to represent a distinct and highly divergent lineage relative to other Calligrapha. The group is given subgeneric status, under the name Erythrographa subgen. nov., based on the morphological features of its representatives, which include reddish testaceous color to dark parts of body, including elytral markings, the presence of two spots enclosed by the humeral lunule, and a bifid end of the flagellum in male genitalia, among other typical features. One of the species of the new subgenus is also new and formally described as Calligrapha synthesys sp. nov. All the species of the subgenus Erythrographa subgen. nov. are found in Mexico (with the exception of C. wickhami, only known from southern Texas), with five species with larger distributions, reaching Nicaragua (C. notatipennis Stål), Costa Rica (C. labyrinthica Stål) or Panama (C. suboculata Stål, C. synthesys sp. nov. and C. tortilis Stål). The subgenus can be considered Neotropical, endemic of Central America and particularly diverse in the Mexican Transition Zone, between the Nearctic and Neotropical realms.

Nearctic Region

A transition zone shows the overlap between two or more regions and represents an event of biotic hybridisation, where different cenocrons assembled as a result of historical and ecological processes. The Mexican transition zone, the area where the Nearctic and Neotropical regions overlap, includes the following five biogeographical provinces: Sierra Madre Occidental, Sierra Madre Oriental, Sierra Madre del Sur, Transmexican Volcanic Belt and Chiapas Highlands. Within this transition zone, the following five cenocrons have already been recognised: Paleoamerican, Mexican Plateau, Mountain Mesoamerican, Nearctic and Typical Neotropical. We undertook three cladistic biogeographic analyses on the basis of 49 cladograms of terrestrial taxa, partitioning them into three time-slices, namely, Miocene (Mountain Mesoamerican cenocron), Pliocene (Mountain Mesoamerican plus Nearctic cenocrons) and Pleistocene (Mountain Mesoamerican, Nearctic and Typical Neotropical cenocrons). For the Miocene time-slice, we observed a close relationship of the Transmexican Volcanic Belt with the Neotropical region, whereas, for the Pliocene and Pleistocene time-slices, the closest relationship of the Transmexican Volcanic Belt was with the Nearctic region. We conclude that the Transmexican Volcanic Belt may have played a different role according to the cenocron analysed, and that the Mexican transition zone differs in its delimitation depending on the taxa analysed, strengthening the idea that it is a complex area.

New World species of the genus Incisitermes Krishna, 1961 range from California to Peru.  The soldier of this genus is notable for the incised anterior margin of the pronotum and the elongated third antennal article.  I report the broad occurrence of Incisitermes platycephalus (Light, 1933) from extreme southern Mexico to the Pacific coast of Nicaragua. Incisitermes nigritus (Snyder, 1946) from Guatemala is a junior synonym of I. platycephalus.  Among Incisitermes, I.  platycephalus is characterized by its small size, dark imago, and dorsoventrally compressed soldier head capsule.

The species of the New World genus Ecnomocephala Gibson (Hymenoptera: Chalcidoidea: Eupelmidae: Eupelminae) are revised. Seven species are recognized, the type species, E. townesi Gibson, 1995 (♀♂: USA), and the following six new species: E. ashei Gibson n. sp. (♀♂: French Guiana, Guyana, Venezuela), E. boliviensis Gibson n. sp. (♀: Bolivia), E. gilli Gibson n. sp. (♀♂: Brazil, Costa Rica, Panama), E. hypha Gibson n. sp. (♀: Costa Rica), E. retia Gibson n. sp. (♀: Mexico), and E. speculum Gibson n. sp. (♀: Colombia, Ecuador, Peru). The species are illustrated through macrophotography and keyed. Morphology of the sexes is compared to each other relative to sexual dimorphism and examined for implications for inferring function, character-state evolution, and phylogenetic relationships within the subfamily.

The genus occurs from Jamaica and southern Mexico to southern Brazil, Paraguay, and Bolivia. One species has been reared from the fruit of Styrax (Styracaceae), one from a fungus gall on Inga longispina (Fabaceae), and one from the stem of Vernonia (Asteraceae). We re-examine phylogenetic relationships among Anopinella and its putative related genera, Seticosta Razowski, Punctapinella Brown, Strophotina Brown, and Apolychrosis Amsel. We synonymize Ecuadorica Razowski & Becker, 2000, with Anopinella.

The phylogenetic relationship between the two extant subfamilies of Ptychopteridae is examined using morphological characters. Bittacomorphinae is supported as a monophyletic group with several synapomorphies. Monophyly of the Ptychopterinae is less certain. Descriptions are provided for the family and subfamilies. The genera and species of Bittacomorphinae are reviewed, and phylogenetic relationships within the subfamily are discussed. While Bittacomorpha is a monophyletic group, Bittacomorphella is probably paraphyletic. Redescriptions of the species of Bittacomorpha and most of Bittacomorphella are presented. Bittacomorphella furcata sp. nov, is described from the central Coast Range of Oregon and Olympic Peninsula of Washington, USA. The range of Bittacomorphinae is found to extend into the Neotropical region with a record of Bittacomorpha clavipes from Costa Rica. A key to the world species of Bittacomorphinae is provided. Printed copy of this book is available from US$25.8 plus postage, Click here to order.

We provide a map of the 14 biogeographic provinces of Mexico based on the ecoregions recognized for the country, which combine climatic, geological and biotic criteria. These provinces belong to the Nearctic region (Californian, Baja Californian, Sonoran, Chihuahuan Desert and Tamaulipas provinces), Neotropical region (Pacific Lowlands, Balsas Basin, Veracruzan and Yucatán Peninsula provinces) and the Mexican transition zone (Sierra Madre Occidental, Sierra Madre Oriental, Transmexican Volcanic Belt, Sierra Madre del Sur and Chiapas Highlands provinces). In order to facilitate future biogeographic analyses, we provide a file of the biogeographical regionalisation of Mexico by converting the map into a polygon shapefile and a raster file with all provinces. We also separately provide each of the provinces in vector and raster format. All the maps are in geographical and Lambert Conformal Conic projections.

Furcidentia Zettel, 1990 (Braconidae: Cheloninae) from the New World has been recently recognised as a genus separate from Pseudophanerotoma Zettel, 1990. Previously known from three species, three additional new species of Furcidentia are described here from the Neotropical region: F. jenningsi sp. nov. (French Guiana), F. llama sp. nov. (Guatemala), and F. tikalensis sp. nov. (Guatemala). The species F. clypeata Zettel (Ecuador) comb. nov., F. pulchra Zettel (Costa Rica) comb. nov., and F. sharkeyi Zettel (Ecuador) comb. nov. are transferred to Furcidentia. Additionally, one new species of Pseudophanerotoma is described: P. austini sp. nov. (Guatemala), while P. paranaensis (Costa Lima) (Brazil) and P. thapsina (Walley) (Texas, USA) are redescribed and are here recorded from French Guiana for the first time, thus considerably expanding their known distribution. Redescriptions include the description of the male of P. thapsina (Walley) for the first time and of the female of P. paranaensis (Costa Lima). Identification keys to the Neotropical genera of Phanerotomini and the species of Furcidentia and Pseudophanerotoma are provided.
