Analysis of the Geographical Distribution of Paraphlebia zoe Selys in Hagen, 1861 (Odonata: Megapodagrionidae)

ABSTRACT: Paraphlebia zoe Selys in Hagen, 1861, an endemic Mexican species included in the IUCN Red List of threatened species, is recorded for the first time in Querétaro state. Based on recent collections in mountain cloud forests during the dry and rainy seasons, we added three new records for Hidalgo. There were compiled 16 historical records of the species, that permitted us to generate a range map for P. zoe showing that most records are from the southern region of the Sierra Madre Oriental with some records from the Mexican Gulf provinces. This distributional pattern also occurs in several species of Staphylinidae, Passalidae and Scarabaeidae.

Discovery of the Male of Homalolinus tlanchinolensis Márquez and Confirmation of Renda debilis (Sharp) (Coleoptera: Staphylinidae: Xantholinini) from Mexico

The Neotropical species of Xantholinini of the genera Heterolinus Sharp, Homalolinus Sharp, Plochionocerus Dejean, and Renda Blackwelder have been the object of recent study (Márquez 2001, 2003, 2010; Asiain 2006; Asiain et al. 2007). The latter works yielded a significant increase of new species: one for Heterolinus, 20 for Homalolinus, eight for Plochionocerus, and 20 for Renda. In addition, preliminary phylogenetic hypotheses have been proposed. Many species are known from only one sex and from few specimens, and our knowledge of their biology and distribution is poor. Homalolinus tlanchinolensis Márquez, 2003 was described based on three female specimens from Tlanchinol, Hidalgo, Mexico. This species is sympatric with and is morphologically similar to Homalolinus divisus (Erichson, 1839), but was considered a separate species based on non-sexual characters, even though characters of the often diagnostic aedeagus were not known. Based on one female specimen, Márquez (2006) recorded H. tlanchinolensis from Huayacocotla, Veracruz, Mexico, a place near the type locality, but in a different Mexican state. The only specimen of Renda debilis (Sharp, 1885) known from Mexico is an old specimen without detailed locality data (Márquez 2010). The purpose of this note is to describe the male of H. tlanchinolensis, provide an illustration of its aedeagus and a comparison between it and the aedeagus of H. divisus, and confirm the presence of R. debilis in Veracruz, Mexico. Six specimens of H. tlanchinolensis and one specimen of R. debilis were recently collected in the state of Veracruz, Mexico. The H. tlanchinolensis specimens are deposited in the Coleoptera Collection of the UAEH (CC-UAEH, Pachuca, Hidalgo, Mexico; J. Márquez), and the specimen of R. debilis is deposited in the Entomological Collection of the Instituto de Ecología, A.C. (IEXA, Xalapa, Veracruz, Mexico; M. A. Morón). The H. tlanchinolensis specimens were compared with several Mexican specimens of H. divisus deposited in the CC-UAEH. Terminology and nomenclature follows that of Márquez (2003, 2010).

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.

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.

Distribution Patterns of the Mexican Species of Carrion Beetles (Coleoptera: Silphidae)

Abstract Silphidae in Mexico, as in other countries, are a broadly studied family of Coleoptera. However, their geographical distribution in this country has been poorly analyzed. The aim of this study was to perform a track analysis of the Mexican species of Silphidae to discuss their distribution patterns. We used bibliographic and new distribution data of 11 Mexican species of Silphidae to construct their individual tracks in maps of biogeographic provinces. The superposition of these tracks allowed detection of generalized tracks, which were compared with previously published distribution patterns to propose hypotheses of primary biogeographic homology. We record Nicrophorus olidus Matthews, 1888 for the first time in Nicaragua and confirm its presence in Honduras. Additionally, three species are new state records for Aguascalientes, and new localities are provided for seven species. We recovered three main distribution patterns. Four species correspond to the Californian Nearctic pattern, followed by the continental Nearctic plus the montane Mexican pattern represented by three species, and the Mesoamerican plus the montane Mexican pattern constituted by two species. Each of the last two species showed a unique distribution. Seven of the 11 Mexican silphid species show Nearctic affinity, three have a Neotropical affinity, and one is endemic to the montane Mexican component. Patterns detected for Mexican silphids have been documented for other families of Coleoptera, thus they can be postulated as hypotheses of biogeographic primary homology. These hypotheses should be tested with other biological groups, and their causes need to be investigated with different historical biogeographical methods.

PRELIMINARY ANALYSIS OF THE COLOR VARIATION IN CYPARIUM TERMINALE FROM MEXICO, WITH COMMENTS ON C. PALLIATUM, AND A NEW RECORD FOR C. YAPALLI (COLEOPTERA: STAPHYLINIDAE, SCAPHIDIINAE)

ABSTRACT Preliminary analysis of the color pattern of the body, antennae, head, pronotum, pronotal hypomeron, elytra, elytral epipleura, and last two visible pregenital tergites of Cyparium terminale Matthews is presented based on specimens from four Mexican states. Taxonomical remarks are included for C. palliatum Erichson based on study of the holotype. To augment the poor original description of C. palliatum, the holotype is compared to specimens of C. terminale. Cyparium yapalli Fierros-López is reported from the state of Guerrero for the first time and from a new locality in the state of Oaxaca.
