A New Species

The Ambrysus pudicus Stål species complex is revised, its species diagnosed, and an illustrated key is presented. The complex includes A. abortus La Rivers, A. amargosus La Rivers, A. funebris La Rivers, A. hungerfordi Usinger, A. parviceps Montandon, A. pudicus Stål, and A. relictus Polhemus & Polhemus. A new species, A. chinanteco, belonging to this complex is described from southern Mexico. The subspecies A. hungerfordi angularis La Rivers, A. h. spicatus La Rivers, and A. h. triunfo La Rivers are herein elevated to full species level and considered members of this species complex. The subspecies A. pudicus barberi Usinger is synonymized with the nominate subspecies. Based on specific combinations of morphological features, two subcomplexes of species are recognized within the complex. The species A. funebris is transferred from the subgenus Acyttarus La Rivers to the subgenus Ambrysus Stål. In order to fix the identity of three species in the complex, neotypes for A. amargosus and A. spicatus and a lectotype for A. pudicus are designated here. The species in the A. pudicus complex are distributed in North America from the southwestern and southern United States to northern Costa Rica. New country records from Central America are presented for A. parviceps and A. pudicus. New state records from Mexico are presented for A. abortus, A. angularis, A. hungerfordi, A. parviceps, A. pudicus, and A. spicatus.

A New Species

Moraria hudsoni n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA. The new species differs from its congeners in chaetotaxy, body ornamentation, and other characters. We review published records of members of Moraria from North and Central America; no species is known from South America. Species of this genus have been found in the mountains of southern Mexico, Guatemala, and Honduras, but none of these has been validly described. In North America, eight species have been recorded from Alaska, Canada, and the conterminous USA as far south as North Carolina. We report new geographical records of M. affinis from Virginia, and of both M. cristata and M. virginiana from Maryland and Virginia. We provide a tabular key to aid in identification of the named species of Moraria in North America.

Competition For Resources

AbstractA new species of gopher, Gregorymys mixtecorum n. sp., is described from the Arikareean 1 (early Oligocene) of Oaxaca, southern Mexico. Phylogenetic analysis indicates that it is the sister species of G. veloxikua, which was also recently described from southern Mexico. Both species were collected from sediments of the Chilapa Formation that crop out in northwestern Oaxaca. Gregorymys mixtecorum n. sp. and G. veloxikua show differences in size and proportions that possibly reduced competition for resources, exploiting different microhabitats. Both Mexican species represent the oldest and the most southern records of Gregorymys in North America. The Mexican record of Gregorymys suggests that at least some entoptychine rodents diversified in southern Mexico or Central America, and that Geomyidae has had a wide geographic distribution in North America since the early Oligocene.UUID: http://zoobank.org/0f4ad549-2f59-442b-87fa-5c9be0573ea4

Iucn Criteria

High-throughput sequencing, when combined with taxonomic expertise, is a powerful tool to refine and advance taxonomic classification, including at the species level. In the present work, a new species, Plantago campestris, is described out of the P. commersoniana species complex, based on phylogenomic and morphological evidence. The main morphological characters that distinguish the new species from P. commersoniana are the glabrous posterior sepals and the slightly broader leaves. The new species is known from only three localities, all in natural high-elevation grasslands in Paraná and Santa Catarina states, southern Brazil. According to the IUCN criteria new species should be assessed as Endangered (EN). We present field photographs of P. campestris and related species, and we provide an identification key to the species previously included within the circumscription of P. commersoniana.

A New Species

A new species of bee fly of the genus Chrysanthrax Osten Sacken, C. pennyi, n. sp., is described and illustrated. It was reared from the larva of a myrmeleontid, which marks the first record of parasitism by the genus of that family. The pupal exuvium is described and illustrated and a key to species known from Central America is given.

A New Species

AbstractCopris incertus Say, 1835 (Coleoptera: Scarabaeidae: Scarabaeinae: Coprini) has been described as a New World coprophagous scarab distributed from Mexico to Ecuador with large discontinuities in its range between the Yucatán province and Costa Rica. The C. incertus species complex of the Copris minutus (Drury, 1773) species group consists of C. incertus, Copris laeviceps Harold, 1869, and Copris lugubris Boheman, 1858. Based on external morphology and male genitalia, we discovered that multiple species have been classified as C. incertus. Of these species, five are new: Copris amazonicusnew species, Copris brevicornisnew species, Copris davidinew species, Copris moroninew species, and Copris susanaenew species. Herein, we revise the organisation of the C. incertus species complex and propose a new species complex, the C. laeviceps species complex, which includes: C. davidi, Copris igualensis Warner, 1990, and C. laeviceps, formerly included in the C. incertus species complex. We provide an identification key along with species distribution maps, images of habitus, and diagnostic characters.

A New Species

A new species of pseudothelphusid crab, Allacanthos yawi n. sp., from the Río Volcán drainage, Puntarenas Province, southern Costa Rica, Central America, is described and illustrated. This is the second species to be assigned to the genus Allacanthos Smalley, 1964. The new species is distinguished by its congener by having a first gonopod with a mesiolaterally flattened distal portion, a concave and nearly smooth subdistal portion of the lateral and cephalic sides, a narrow marginal process with a nearly straight distal border, and a lateral lobe with a sharp tip on the apex. An amended diagnosis for Allacanthos is provided.

A New Species

Bothriomyrmex paradoxus Dubovikov and Longino sp. nov. is described from Costa Rica, based on two collections from widely separated localities. These are the first collections of the genus Bothriomyrmex in the Americas. The genus Bothriomyrmex can be divided into Palearctic species (Both- riomyrmex s.s.) and Oriental and Australian species, based on differences in palp formula and queen wing venation. Bothriomyrmex paradoxus shares palp and wing characters with the Palearctic species. It is probably native to Central America and long separated from its Old World relatives.

A new species of Deltaspis Audinet-Serville (Coleoptera: Cerambycidae: Cerambycinae) from Mexico

Shared Character

As currently defined, the genus Deltaspis Audinet-Serville, 1834, contains 16 species ranging in distribution from the southwestern United States to eastern Mexico. However, the generic distinction between Deltaspis and its closely allied genera, such as Crossidius LeConte, 1851 and Muscidora Thomson, 1864, is in need of clarification. According to Audinet-Serville, Deltaspis is so named due to its distinctive triangular scutellum (i.e., Δετα, delta, ασπιζ écusson), which is actually a commonly shared character of all these genera. Members of the tribe Trachyderini Dupont (1836), which includes the above genera, also have mandibles with an emarginate-truncate apex with the edge chisel-like or bifid. This modification of mouthpart appears to be for consumption of pollen and/or petals from composite flowers visited by the adult beetles (Krenn et al., 2005; Beierl & Barchet-Beierl, 1999). Other genera from this tribe with this modification of mandibles from North America, and mostly from Mexico, include: Chemsakiella Monné, 2006, Giesbertia Chemsak & Linsley, 1984, Hoegea Bates, 1885, Neocrossidius Chemsak, 1959, Paroxoplus Chemsak, 1959, Plionoma Casey, 1912, Schizax LeConte, 1873, and Tylosis LeConte, 1850. The remainder of Trachyderini genera have unmodified or simple mandibles with apex acute.
