An unusual suite of sexual characters in three new species of Hymenorus (Coleoptera,Tenebrionidae, Alleculinae) from Guatemala and Mexico

Two species, Hymenorus bifurcatus, and H. excavatus are described as new from Guatemala and the new species H. balli from both the state of Chiapas in southern Mexico and Guatemala. These three species are unique among the species of Hymenorus Mulsant, 1851 in the unusual and highly modified fifth ventrites of the male and the modified shape of the female ninth tergites. The unusual sexual characters of the males and females are illustrated with photographs. The usage of the generic names Hymenorus Mulsant versus Hymenophorus Mulsant is discussed.     

Review of the species of Paratenetus Spinola inhabiting America,north of Mexico (Coleoptera,Tenebrionidae)

The North American (north of Mexico) species of the tenebrionid genus Paratenetus Spinola are reviewed and a key is presented for their identification. Five species are recognized, P. gibbipennis Motschulsky, P. fuscus LeConte, P. punctatus Spinola and two sp. n., P. exutus [type locality: Tabusintac, Nova Scotia] and P. texanus [type locality: Port Isabel, Cameron County, Texas]. Two syn. n. are proposed: P. cribratus Motschulsky, 1868 with P. gibbipennis Motschulsky, 1868 and P. crinitus Fall, 1907 with P. fuscus LeConte, 1850. A lectotype is selected for Paratenetus punctatus Spinola. A type species is designated for Storthephora Mäklin, 1875 (Storthephora denticollis Mäklin, 1875).

Integrative taxonomy of New Caledonian beetles: species delimitation and definition of the Uloma isoceroides species group (Coleoptera,Tenebrionidae, Ulomini), with the description of four new species

New Caledonia is an important biodiversity hotspot with much undocumented biodiversity, especially in many insect groups. Here we used an integrative approach to explore species diversity in the tenebrionid genus Uloma (Coleoptera, Tenebrionidae, Ulomini), which encompasses about 150 species, of which 22 are known from New Caledonia. To do so, we focused on a morphologically homogeneous group by comparing museum specimens with material collected during several recent field trips. We also conducted molecular phylogenetic analyses based on a concatenated matrix of four mitochondrial and three nuclear genes for 46 specimens. The morphological study allowed us to discover and describe four new species that belong to the group of interest, the Uloma isoceroides group. Molecular analyses confirmed the species boundaries of several of the previously described species and established the validity of the four new species. The phylogenetic analyses also provided additional information on the evolutionary history of the group, highlighting that a species that was thought to be unrelated to the group was in fact a member of the same evolutionary lineage. Molecular species delimitation confirmed the status of the sampled species of the group and also suggested some hidden (cryptic) biodiversity for at least two species of the group. Altogether this integrative taxonomic approach has allowed us to better define the boundaries of the Uloma isoceroides species group, which comprises at least 10 species: Uloma isoceroides (Fauvel, 1904), Uloma opacipennis (Fauvel, 1904), Uloma caledonica Kaszab, 1982, Uloma paniei Kaszab, 1982, Uloma monteithi Kaszab, 1986, Uloma robusta Kaszab, 1986, Uloma clamensae sp. n., Uloma condaminei sp. n., Uloma jourdani sp. n., and Uloma kergoati sp. n. We advocate more studies on other New Caledonian groups, as we expect that much undocumented biodiversity can be unveiled through the use of similar approaches.

Revision of the genera Hovadelium Ardoin and Mimolaena Ardoin (Coleoptera,Tenebrionidae, Laenini) from Madagascar,with remarks on tribal assignment

The genera Hovadelium Ardoin, 1961 and Mimolaena Ardoin, 1961, endemic in Madagascar, are revised and assigned to the tribe Laenini Seidlitz, 1896 (subfamily Lagriinae Latreille, 1825). New species: Hovadelium ardoini sp. n., Hovadelium bremeri sp. n. and Mimolaena janaki sp. n. An identification key is compiled for all taxa. Distribution of Hovadelium (5 species) and Mimolaena (3 species) is mapped. The congeners might be indicator species for the highly endangered mature forests in Madagascar.     

Pseudaptinus (Thalpius) nobilis Liebke, new to the United States, and a key to the species of subgenus Thalpius LeConte in North America, including Mexico (Coleoptera, Carabidae, Zuphiini)

The Mexican carabid species Pseudaptinus (Thalpius) nobilis Liebke is documented from the United States for the first time based on two specimens captured in southeastern Texas. A new taxonomic key distinguishes the 10 members of subgenus Thalpius known in North America, including Mexico. Pseudaptinus (Thalpius) dorsalis, which is found to be highly variable in its dorsal coloration, is compared to similar Pseudaptinus (Thalpius) hoegei. Geographic ranges are extended for several species.

New Coleoptera records from New Brunswick, Canada: Tenebrionidae and Zopheridae

Thirteen species of Tenebrionidae are newly reported for New Brunswick, Canada. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded for the first time from the Maritime provinces. Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum Laporte and Brullé for the province is confirmed. This brings the total number of species of Tenebrionidae known from New Brunswick to 42. Two species of Zopheridae, Bitoma crenata Fabricius and Synchita fuliginosa Melsheimer, are newly recorded for New Brunswick, bringing the number of species known from the province to four. Bitoma crenata is new to the Maritime provinces. Collection and habitat data are presented for these species.
