A new species of Oxelytrum Gistel (Coleoptera, Silphidae) from southern Argentina, with a key to the species of the genus.

ABSTRACT: A new species of the forensically interesting genus Oxelytrum Gistel (Coleoptera, Silphidae), Oxelytrum selknan, is described from Santa Cruz and Tierra del Fuego provinces, Argentina. The new species resembles Oxelytrum biguttatum (Philippi) in outer aspect, but has different male genitalia, in particular a median lobe longer than the paramera. All the described species of Oxelytrum have the median lobe shorter than the paramera. The internal sac, as far as it could be reconstructed from dry-pinned specimens, also shows differences between the two species. A key to the species of Oxelytrum is given and illustrated.

Description of Nicrophorus efferens, new species, from Bougainville Island (Coleoptera, Silphidae, Nicrophorinae).

Project description:A new species of Nicrophorus in the nepalensis species-group, Nicrophorus efferens Sikes and Mousseau, is described from Bougainville Island in the Solomon Islands archipelago. It is distinguished from the known species of the genus Nicrophorus and its likely closest relative, Nicrophorus reticulatus Sikes and Madge, based on external morphology. A comparison among the four Nicrophorus species known from the Solomon Island archipelago and Papua New Guinea is presented.

<i>Lophorrhinidesmuellerae</i> (Coleoptera, Scarabaeidae, Cetoniinae): a new genus and species from southern Tanzania.

Project description:A male cetoniine specimen recently submitted for identification from the Ditsong Museum of Natural History (Pretoria, South Africa) has been found to represent a yet unknown species. A review of the recently published book of Beinhundner (2017) has further revealed that one of the specimens mistakenly figured as Lophorrhinadonckieri Bourgoin, 1913 in that work is most likely the female of this new species. Analysis of the diagnostic characters of the genus Lophorrhina Westwood, 1842 shows that the new species differs in several key areas. In particular, the clypeal armature is virtually identical in both sexes, the male protibiae are not typically elongate and narrow as in all the members of Lophorrhina, but are remarkably more robust, laterally expanded and with a tridentate margin in both sexes, even though the third tooth in the female and the second and third teeth in the male are virtually obsolete. The general body shape in the new species is also more globose and lacks the typical deplanate and apically tapering elytra of the Lophorrhina males. These and other characters are, in our view, sufficient to justify the erection of a new genus, Lophorrhinides gen. n., to accommodate the new species, here described as L.muellerae sp. n. The new genus is presumably a mountain specialist, as both known specimens were collected in the southern highlands of Tanzania, at Manow and Rungwe respectively.

Taxonomic revision of genus Ablattaria Reitter (Coleoptera, Silphidae) using geometric morphometrics.

Project description:The genus Ablattaria Reitter, 1884 (Coleoptera: Silphidae: Silphinae) is revised. Four taxa are recognized as valid species: Ablattariaarenaria (Kraatz, 1876), Ablattariacribrata (Ménétries, 1832), Ablattarialaevigata (Fabricius, 1775) and Ablattariasubtriangula Reitter, 1905. Ablattarialaevigatavar.meridionalis Ganglbauer, 1899 is newly treated as a junior subjective synonym of Ablattarialaevigata. Lectotypes are designated for Phosphugaarenaria Kraatz, 1876, Ablattariaarenariavar.punctigera Reitter, 1884, Ablattariaarenariavar.alleoni Portevin, 1926, Silphacribrata Ménétries, 1832, Silphalaevigata Fabricius, 1775, Silphagibba Brullé, 1832, Ablattariagibbavar.costulata Portevin, 1926, Ablattariagibbavar.distinguenda Portevin, 1926, Ablattariagibbavar.punctata Portevin, 1926 and Ablattariasubtriangula Reitter, 1905. The distribution of all taxa is mapped, based on material examined. Geometric morphometric methods were used to evaluate shape variability in Ablattaria. Results indicated sexual dimorphism in all species. Shape inconsistency was found between the sexes of all taxa when tested independently. The first two relative warp axes indicated 65.17% shape variation in males and 65.72% in females. Canonical variate analysis separated the taxa studied. There was minimal overlap between some groups in both sexes. Differences in body shape between populations of Ablattarialaevigata from Central Europe, Italy and Greece + Turkey were also examined. Relative warps implied 58.01% shape variability on both axes in males and 64.78% in females. CVA revealed noticeable overlaps between the groups, although the Italian population demonstrated a higher separation in both sexes.

A new species of Oileus Kaup (Coleoptera, Passalidae) from Guatemala, with a key to the species of the genus.

Project description:Oileus gasparilomisp. n. is described from nine specimens from the mountains of Quiché in Guatemala, from cloud forest at 1795 m elevation.

A key to the species of Oileus is given.

Two new species of the genus <i>Anillinus</i> Casey (Coleoptera, Carabidae, Anillini) from the southern United States.

Project description:Two new species of blind ground beetles are described from the southern United States. One species, Anillinus relictus sp. nov. (type locality: E of Oneonta, Blount County, Alabama), based on the structure of male genitalia, is similar to Texan Anillinus, in particular to the endogean A. sinuatus Jeannel. The second species, A. felicianus sp. nov. (type locality: 4 mi SW Jackson, West Feliciana Parish, Louisiana), is superficially similar to the endogean A. sinuaticollis Jeannel from Roane County, Tennessee, and represents the first record of the genus for the state of Louisiana. All species are illustrated with digital images of habitus, body parts, and male and female genitalia. Biogeographical and evolutionary implications of the new findings are discussed.
