Three New Species of the Philonthus furvus Species Group (Coleoptera: Staphylinidae) from Guatemala and México, with Taxonomic Remarks and Distributional Records of Related Mexican Species

ABSTRACT Three new species of Philonthus furvus species group with orange elytra are described: P. rufotibialis sp. nov. from Chiapas (Mexico) and San Marcos (Guatemala); P. pollens sp. nov. from Morelos (Mexico) and P. navarretei sp. nov. from Oaxaca (Mexico). Diagnostic features, new state and locality records for P. hoegei, P. testaceipennis and P. yaqui are included. Also, a key to identify the six species recorded from Mexico and the species shared with Guatemala is presented, with some schemes of the most important structures.

The Staphylinidae (Coleoptera) Fauna of Los Mármoles National Park, Hidalgo, Mexico

ABSTRACT Staphylinid beetles were collected from May to December 2007 using several different sampling methods at three sites in Los Mármoles National Park, Hidalgo, Mexico. Two sampling sites were in pine—oak forest and one was in oak forest. In addition, records were included from less structured occasional collecting at other sites in the park. A total of 2,680 specimens belonging to 111 species, representing 91.7% of the 121 species currently known in Hidalgo state, were collected. The highest number of species and specimens were recorded at Las Trancas (Zimapán), followed by Minas Viejas and La Encarnación. These were the three sites where systematic collections were made, using a wide variety of methods. The highest number of staphylinid species was recorded in sifted leaf litter, followed by dung traps and carrion traps. The present contribution can help to identify the taxa inhabiting this protected natural area and aid in understanding the importance of continuing to conserve them.

A NEW SPECIES OF PLOCHIONOCERUS (COLEOPTERA: STAPHYLINIDAE: XANTHOLININI) FROM COSTA RICA, VENEZUELA, AND ECUADOR

ABSTRACT A new species of Plochionocerus Dejean, 1833 is described, based on six specimens from Costa Rica, one from Venezuela and one from Ecuador. Dorsal habitus and diagnostic structures for its identification, as well as geographical and biological data, are provided.

New Records of Coleoptera from the State of Hidalgo, Mexico

ABSTRACT: We report the first time for the state of Hidalgo, Mexico, the following five species of Coleoptera: Tetracha carolina (Linnaeus, 1766) (Carabidae, Cicindelinae), Chalcolepidius lafargi Chevrolat, 1835 (Elateridae), Aegithus cardinalis Chevrolat, 1834, Gibbifer boisduvali Chevrolat, 1834 (Erotylidae) and Renda debilis (Sharp, 1884) (Staphylinidae). We also provide a precise locality for Euchroma gigantea Linnaeus, 1758 (Buprestidae). It is unknown whether it has been previously recorded for this state. Some biological comments also are included for each species.

First State Records for Three Mexican Staphylininae (Coleoptera: Staphylinidae) with Comments on Their Distributional Patterns

ABSTRACT Three poorly known Mexican species of Staphylininae are recorded for the first time from four states, namely Philonthus pollens Márquez and Asiain, 2010 from Estado de México and Michoacán, Phanolinus speciosus Sharp, 1884 from Chiapas and Plochionocerus discedens (Sharp, 1885) from Jalisco. Their distribution is described based on previously detected distributional patterns for staphylinids and other beetles, as well as in relation to the Mexican biogeographic provinces and biotic components.

Comentarios taxonómicos sobre Oxyporus flohri Sharp (Coleoptera: Staphylinidae) y primer registro de la especie para el Estado de Hidalgo, México

Oxyporus flohri Sharp is recorded for the fi rst time from Hidalgo State, Mexico. The description and illustration of the aedeagus of this species based on four specimens (three males and one female) is provided for the first time. The geographic distribution, the general morphometric variation of the specimens from Hidalgo State and the intraspecific color variation based on the specimens recently collected, and the information of previous publications are included. Additionally, biological information over this species is included.
