A rich fauna of subterranean short-range endemic Anillini (Coleoptera, Carabidae, Trechinae) from semi-arid regions of Western Australia.

Globally, the great majority of Anillini species are endogean, adapted to live in the interstices of soil and leaf litter, while the extremely low vagility of these minute ground beetles gives rise to numerous shortrange endemic species. Until recently the Australian Anillini fauna was known only from leaf litter in rain forests and eucalypt forests in the wetter, forested regions of eastern and south eastern Australia, as well as Lord Howe and Norfolk islands. The first hypogean Anillini in Australia (17 species in six genera) were described in 2016 from mineral exploration drill holes in iron-ore bearing rocks of the Pilbara region in Western Australia, representing the first finding of the tribe deep underground in a semi-arid climate region. A further eight new genera and 20 new species are described herein, mostly from the Pilbara region as well as the semi-arid Kimberley and Goldfields regions; all were collected in mineral exploration drill holes. The following new genera are described: Erwinanillus gen. nov., Gregorydytes gen. nov., Pilbaraphanus gen. nov., Neoillaphanus gen. nov., Kimberleytyphlus gen. nov., Gilesdytes gen. nov., Pilbaradytes gen. nov., and Bylibaraphanus gen. nov. The following new species are described: Erwinanillus baehri sp. nov.; Gracilanillus hirsutus sp. nov., G. pannawonicanus sp. nov.; Gregorydytes ophthalmianus sp. nov.; Pilbaraphanus chichesterianus sp. nov., P. bilybarianus sp. nov.; Magnanillus firetalianus sp. nov., M. sabae sp. nov., M. salomonis sp. nov., M. regalis sp. nov., M. serenitatis sp. nov.; Neoillaphanus callawanus sp. nov.; Kimberleytyphlus carrboydianus sp. nov.; Austranillus jinayrianus sp. nov.; Gilesdytes pardooanus sp. nov., G. ethelianus sp. nov.; Pilbaradytes abydosianus sp. nov., P. webberianus sp. nov.; Bylibaraphanus cundalinianus sp. nov.; and Angustanillus armatus sp. nov. Identification keys are provided for all Australian anilline genera, and Western Australian species. All the described species are known from a single locality and qualify as short-range endemics. The Anillini are recognised as a significant and diverse element making up part of Western Australia's remarkable subterranean fauna, and whose conservation may potentially be impacted by mining developments.

The genus Diplocheila Brullé, 1834 in Cambodia, with descriptions of two new species (Coleoptera, Carabidae, Licinini).

The Diplocheila species recorded from Cambodia are discussed and two new species, Diplocheila walterrossii sp. nov. and D. erwini sp. nov. are described. Moreover, the holotypes of D. laevigata (Bates, 1892) and D. laevigotoides Jedlicka, 1936, two often misinterpreted species from the Oriental Region, are illustrated and some aspects of their morphology are clarified. Finally, an analytical key to all species recorded from Cambodia is provided.

Abacaecus n. gen. walterrossii n. sp., a notable hypogean carabid species from Sierra Leone, Western Africa (Coleoptera, Carabidae, Pterostichinae).

Abacaecus n. gen. walterrossii n. sp., a notable blind species from Sierra Leone, is described. A. walterrossii n. sp. probably belongs to a separated phyletic lineage inside Abacetini sensu lato and is the first recorded blind African species of this tribe. It is also compared to Pterostillichus caecus Straneo, another African blind species of uncertain affinities, of which is given an integrative description enriched by illustration of a few characters.

Synonymic notes on Trechini from Argentina (Coleoptera: Carabidae: Trechinae).

Nine new Trechisibus species from South America (Peru and Patagonian Argentina) were recently described (Allegro & Giachino 2016). Five of them were based on material labelled "Argentina, Neuquen, Pen. Quetrihué" offered to the authors for study by its collector (Riccardo Sciaky). Shortly after publication, Martin Donabauer kindly communicated that a mistake probably had occurred, as they are five well known European Trechus species from Koralpe (Austria) living in low subalpine forests at 1200-1700 m a.s.l. As a subsequent control allowed us to ascertain that the collector had stayed in Koralpe collecting some material, a mistake evidently occurred in labelling, misleading a correct taxonomic interpretation of these species by the authors.

Nine new Trechisibus species from Peru and Argentina (Coleoptera: Carabidae: Trechinae).

Nine new Trechisibus species are described, four from Central Peru (T. huascarani n. sp. and T. recuayi n. sp. from Dept. Ancash, T. curtii n. sp. and T. lemairei n. sp. from Dept. Huanuco) and five from Patagonian Argentina, Province of Rio Negro (T. brevis n. sp., T. longipenis n. sp., T. parvulus n. sp., T. sciakyi n. sp., T. striatus n. sp.).

Ecology and sampling techniques of an understudied subterranean habitat: the Milieu Souterrain Superficiel (MSS).

The term Milieu Souterrain Superficiel (MSS) has been used since the early 1980s in subterranean biology to categorize an array of different hypogean habitats. In general terms, a MSS habitat represents the underground network of empty air-filled voids and cracks developing within multiple layers of rock fragments. Its origins can be diverse and is generally covered by topsoil. The MSS habitat is often connected both with the deep hypogean domain-caves and deep rock cracks-and the superficial soil horizon. A MSS is usually characterized by peculiar microclimatic conditions, and it can harbor specialized hypogean, endogean, and surface-dwelling species. In light of the many interpretations given by different authors, we reviewed 235 papers regarding the MSS in order to provide a state-of-the-art description of these habitats and facilitate their study. We have briefly described the different types of MSS mentioned in the scientific literature (alluvial, bedrock, colluvial, volcanic, and other types) and synthesized the advances in the study of the physical and ecological factors affecting this habitat-i.e., microclimate, energy flows, animal communities, and trophic interactions. We finally described and reviewed the available sampling methods used to investigate MSS fauna.

Annotated checklist of the Blennidus subgenus Agraphoderus species from Peru with description of B. bombonensis n. sp. and synonymic notes (Coleoptera: Carabidae: Pterostichinae).

Forty species belonging to the subgenus Agraphoderus of Blennidus have been recorded so far from Peru. An annotated checklist is provided with information about their type locality, distribution and habitat. The nomenclature of each species is also provided, together with some notes on their systematic status. Blennidus bombonensis n. sp. from Cerro de Pasco is described; Blennidus pseudangularis nomen novum for Ogmopleura angularis Straneo, 1993 (nec Straneo, 1985) is proposed and the following synonymies are stated: Blennidus pseudangularis Allegro & Giachino, nomen novum = Blennidus rectangulus (Straneo, 1993) syn. nov.; Ogmopleura minor Straneo, 1993 = Blennidus rectangulus (Straneo, 1993) syn. nov. Type specimens of most species are illustrated, as well as male genitalia. Finally, a revised key to all the Agraphoderus species from Peru is provided.

Two new species of Oxytrechus Jeannel, 1927 from Ecuador (Coleoptera, Carabidae).

Two new species of Oxytrechus Jeannel 1927 are described from the páramos of the Ecuadorian Andes in Pichincha province (Ecuador: Northern Sierra): O. osellai n. sp. from Cangahua at 3375 m a.s.l. and O. belloi n. sp. from Paso de la Virgen at 3515 m a.s.l.

A new remarkable subterranean beetle of the Rhodopes: Paralovricia gen. n. beroni sp. n. belonging to Lovriciina new subtribe (Coleoptera, Carabidae, Trechinae, Bembidiini).

Paralovriciagen. n.beronisp. n., belonging to the new subtribe Lovriciina, is described from two caves in the Western Rhodopes (Bulgaria): Kraypatnata peshtera, near Smilyan Village (Smolyan Municipality) and Snezhanka, near Peshtera Town (Peshtera Municipality). Three currently known genera, Lovricia Pretner, 1979, Neolovricia Lakota, Jalzic & Moravec, 2009 and Paralovriciagen. n. represent a monophyletic unit supported by important synapomorphies that allows to propose the establishment of the new subtribe Lovriciina, characterized by the following characters: last maxillary palpomeres very long and narrow, basal angles of pronotum without seta, elytra without discal setae, elytral umbilicate series of nine pores in which the main pores are the 2nd, 6th and 9th, apical recurrent striole absent and mesotibial apex expanded outward. Its systematic position within the subfamily Trechinae (sensu Lorenz 2005) is discussed and Lovriciina is placed near Anillina. Key to the genera of the subtribe is proposed. Distribution data and zoogeographical hypotheses are discussed.
