Discovery of the diving beetle Laccornis oblongus (Stephens, 1835) in Bavaria, southern Germany (Coleoptera, Dytiscidae, Hydroporinae, Laccornini)

The diving beetle Laccornis oblongus (Stephens, 1835) is recorded for the first time from Bavaria, southern Germany, which marks the most south-westerly record of the species known to date. Three specimens were collected in the Murnauer Moos nature reserve in Upper Bavaria. We summarize what is known about the species habitat in Germany and provide photographs of the sampling site and habitus, median lobe of aedeagus, and paramere of the species. We provide a checklist of the 20 other diving beetle species we found syntopic with L. oblongus. 

Tsounkranaglenea hefferni gen. et sp. nov. from Sabah, Malaysia (Coleoptera, Cerambycidae, Lamiinae: Saperdini)

A new saperdine species belonging to a new genus, Tsounkranaglenea hefferni gen. et sp. nov., is described from Sabah, Malaysia. The new genus differs from other genera of the tribe Saperdini by the special male sternite VII modified into a rake-shape, with the apex of the ventral plate of the median lobe unusually emarginated.

Two new ultraspecialized troglomorphic Leptodirini from Croatia (Coleoptera, Leiodidae, Cholevinae)

Two new ultraspecialized troglomorphic Leptodirini (Coleoptera, Leiodidae, Cholevinae) from two Croatian caves are described. Hygrodromus (new genus) nikolinae, a new species from Mladenova cave near Orebić, is a very enigmatic taxon of “tetramerous”Leptodirini, markedly distinct for several morphological features in antennae, mouthparts, male genitalia and the peculiar sexually dimorphic apex of elytra. However, because of some characters, it could be assigned to the phyletic lineage of Hadesia and Nauticiella, which so far includes only “pentamerous”species. Leptomeson vuicae from Dragina lipa jama cave near Čelopek in central Dalmatia, owing to its morphological features, is the south-eastern substitutive adelphotaxon of L. dombrowskii, from which it differs by its smaller size, longer elytral pubescence and the different shape of the median lobe of the aedeagus with a stouter apex.

A case of allopatric speciation in the Central System (Iberian Peninsula): Leistus elpis sp. nov., a sibling species of Leistus constrictus (Coleoptera, Carabidae)

The aim of this work was to demonstrate that the Leistus (Leistus) constrictus Schaufuss 1862 populations from Sierra de Ayllón belong to a new sibling species of the true L. (L.) constrictus from Sierra de Guadarrama. We describe Leistus (Leistus) elpis sp. nov. The species were separated by the study of external morphology of qualitative characters, especially male genitalia, and quantitative characters (morphometric analysis). In L. (L.) constrictus the apical lamina of the aedeagus appears to be a long gutter flanked by lateral ridges with an open truncation in its anterior part; in L. (L.) elpis sp. nov. the apical lamina is completely ridged, even in the anterior part, forming a kind of labial thickening, enclosing the median lobe, and giving the apex a clearly closed and pointed outline. It is not possible, or very difficult, to distinguish between females of L. (L.) constrictus and females of L. (L.) elpis sp. nov., based on their external anatomy as they are practically identical. The female genitalia do not offer taxonomic information for discriminating between the species using the genital armour or the structure of the spermathecal complex. However, subtle differences were found through morphometric analysis, as well as for males of both species. Field surveys suggest that the pass Puerto de Somosierra is the geographical barrier that has led to this allopatric speciation.

Anthrenus (s. str.) corona (Coleoptera, Dermestidae, Anthrenini): a new species in the A. pimpinellae Fabricius, 1775 complex from Turkey

A new species from Turkey, Anthrenus (s. str.) corona, belonging to the Anthrenus pimpinellae complex is presented. The species is described from a single specimen discovered in the collection held by the Natural History Museum, London. The species was uncovered during the dissection of many specimens for the purpose of curation. The species is compared in detail to A. goliath, the most likely confusion species. An obvious external feature of the specimen is its large size, putting it apart from nearly all other species within the complex. The parameres and median lobe are slim, differing in many ways from A. goliath.

Studies on Neotropical crickets: A new Anurogryllina genus (Orthoptera: Gryllidae: Gryllinae)

Andeogryllus n. gen. including two new species from the inter-Andean slopes and valleys of the Magdalena and Cauca rivers of Colombia are described. This new genus is similar to Zebragryllus in their habitus, differed by not have white stripes on the body or antennae and by a modified pseudoepiphallic sclerite. The genus Atsigryllus (Atsigryllae group) is located in the subtribe Anurogryllina, highlighting the secondary reduction of the median lobe. An updated key is provided for the genera of the subtribe Anurogryllina and the species of the new genus.
