The south Indian species of CharaeaBaly, 1878 are revised. The genus CneoridesJacoby, 1896 is synonymized with Charaea. Cneorides flaviventrisJacoby, 1896 is transferred to Charaea and new replacement name Ch. jacobyinom. nov. is proposed for it due to homonymy with Charaea flaviventre (Motschulsky, 1861). Three new species, Ch. boukalisp. nov., Ch. nilgiriensissp. nov. and Ch. sahyadricasp. nov. are described. Lectotype is designated for Cneorides flaviventris. Colour photos of habitus and drawings of both male and female genitalia are presented.

In this paper we describe a new species of a tardigrade of the Macrobiotus hufelandi group from the Tien Shan mountains in Kyrgyzstan. Live specimens extracted from a moss sample were used to establish a laboratory culture in order to obtain more eggs and animals needed for an integrative description of the new species. This description is based on traditional morphological and morphometric data collected using both light and scanning electron microscopy, which at the same time were combined in an integrative approach with DNA sequences of four genetic markers, three nuclear (18S rRNA, 28S rRNA and ITS-2) and one mitochondrial (COI). The analysis showed that Macrobiotus caelestissp. nov. is most similar to Macrobiotus kazmierskiiKaczmarek and Michalczyk, 2009 from Argentina by having eggs with the persimilis type egg shell surface. However the new species can be easily distinguished from it by having very wide terminal discs on the egg shell processes and a small number of processes around the egg circumference. The use of DNA sequences allowed for the more accurate verification of the taxonomic status of M. caelestissp. nov. as an independent species within the hufelandi group.

The enigmatic Neotropical genus Protandroconnus Franz is redescribed and redefined, based on examination of its type species, P. peruensis Franz. Superficially similar Trichocircusgen. nov. is described, a genus showing bizarre male cephalic modifications. Three new species are described: Trichocircus decorissp. nov. (type species of Trichocircus; Panama), T. antennatussp. nov. (Panama) and T. misersp. nov. (Costa Rica). A first attempt is made to subdivide the Neotropical genera of Glandulariini into informal groups and summarize the current state of knowledge to facilitate further studies, especially descriptions of new genera. Protandroconnus is included in the ‘Microscydmus-Homoconnus-Protandroconnus complex’, whereas Trichocircus is in the ‘Amimoscydmus-Protoconnus-Trichocircus complex'; the groups are proposed based on the presence or absence of the lateral submental sutures, the anterior metaventral process, and three variants of complete and incomplete fusion of the prosternum with the hypomera.

A leptochromine ant-like stone beetle, †Rovnoleptochromus balticussp. nov., is described, based on an exquisitely preserved inclusion in Upper Eocene Baltic amber from Kaliningrad Region. The holotype specimen reveals novel characters, not observed (presumably because of poorer preservation) in the previously known †R. ableptonoides Jałoszyński & Perkovsky of Rovno, Ukraine: three pairs of thick, long setae on the head (on vertex, near each eye and near each antennal insertion). Similar, presumably sensory structures (sensilla chaetica), are known in extant and extinct (Upper Cretaceous) Leptomastacini and the enigmatic Upper Cretaceous †Palaeoleptochromus O'Keefe. However, in these taxa, at most two pairs occur. The new finding broadens the known distribution of †Rovnoleptochromus during the Eocene, and suggests that the paired sensory bristles on the head may represent an ancestral condition in at least some of the tribes currently included in Mastigitae, which have later been partly or completely reduced in most members of this group.

An account of the Anthicidae (ant-like flower beetles) of New Caledonia is presented for the first time. Seventeen species are confirmed for this archipelago, including five new to science: Sapintus (s. str.) monochromussp. nov., Trichananca cheesmanaesp. nov., T. novacaledonicasp. nov., Macratria lipsbergisp. nov. and M. manfredjaechisp. nov. One new combination is made, Sapintus wiesneri (Uhmann, 1993) comb. nov. At least one anthicid species appears to have been introduced by human activities. As a result of the present study, confirmed endemism rate in New Caledonian Anthicidae is about 71%.

Holocanthon is a dung beetle genus distributed across South American open environments such as the Humid Chaco, the Brazilian Cerrado and the Argentinian Espinal, as well as some more forested localities in the southern Atlantic Forest and in the Bolivian and Argentinian Yungas. Considered monospecific for more than 60 years, the genus now includes two species: H. fuscorubrus (Blanchard, 1846), new comb. (= H. mateui Martínez et Pereira, 1956, new junior subjective synonym), from Paraguay, Argentina and southern Brazil, and H. giosilvai Sawaris, Cupello & Vaz-de-Mello sp. nov., known only from three distant localities in Bolivia and southern Brazil. The lectotype of Canthon fuscorubrus is herein designated from the only known syntype, while the holotype and the rest of the type series of H. mateui is deemed to be lost.

A new genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Lembakariagen. nov., is described for Lembakaria saintemariaesp. nov. (type species) and Lembakaria mikeaesp. nov. from the island of Madagascar. Habitus, male and female external and internal genital structures of the new species are illustrated. Lembakaria is probably endemic to Madagascar where it is known to date, only from a southern part of the island and is confined to the vegetation of Spiny Forest Ecoregion.

The bee genus Caupolicana Spinola is most diverse in temperate South America, and poorly represented in Brazil, where only two species (C. gaullei Vachal and C. lugubris Smith) were hitherto known. Here, a third species of the genus (C. rupestris Zama, Ferrari, Coelho and Silveira sp. nov.) in that country, is being described, from the ‘rocky fields’ of Minas Gerais state. Additionally, the male terminalia and the female of C. gaullei are described for the first time. A key to the Brazilian species of Caupolicana is also given.

We describe the new species Temnothorax almeqerisp. nov. from the Asir Mountains, Kingdom of Saudi Arabia based on the worker caste and present a revised key to the Arabian Temnothorax species. The new species is illustrated using Scanning Electron Microscope (SEM). Temnothorax almeqerisp. nov. closely resembles the African species, T. cinatusBolton 1982 from Kenya, but can be distinguished by the following characters: promesonotum and mesosoma in profile meet in an elevated ridge; profile of propodeal spines sharp, long and curved; meosomal sculpture strong; body pilosity more abundant, finer and distinctly longer on mesosoma, petiole and postpetiole; body brown; mandibles, appendages, anterior ¼ portion of first gastral tergite and end of gaster uniform yellow.

Two new fossil Carebara Westwood (1840) species are described from the Late Eocene Bitterfeld and Baltic ambers: C. kutscheri sp. nov. is described based on soldier and workers, and formally could be attributed to the former genus Pheidologeton Mayr, 1862 (now junior synonym of Carebara); its workers differ clearly from those of any known fossil Carebara species by the much bigger, well-developed eyes, while eyes in the other species are vestigial, containing several facets, and soldier is the first known one for the fossil Carebara species. Carebara groehni sp. nov. is described based on male, and differs clearly from males of C. antiqua (Mayr, 1868) by the distinctly longer antennal scape and the shorter funicular segments. Furthermore, it is somewhat smaller (the total length is ca. 4 mm vs. ca. 5 mm in C. antiqua), with the gradually rounded propodeum, while propodeum in the latter species is slightly angulate. Additional data for males of C. antiqua, including morphometrics, is provided. Taxonomic position of several fossil species ascribed to Carebara, is discussed.

Stenocorse (Braconidae) is a doryctine wasp genus widely distributed from southern USA to central Argentina, and it has been reported to be ectoparasitoid of over 60 bruchine (Coleoptera: Chrysomelidae) species. The genus currently contains a single described species, S. bruchivora (Crawford), though recent molecular and morphological evidence revealed that it is actually composed of various undescribed species. Here we redescribe S. bruchivora (Crawford) and describe five new species from various geographic regions along the Neotropics (S. atlanticussp. nov., S. maesoi sp. nov., S. pacificus sp. nov., S. rosabricenae sp. nov., S. sudamericanus sp. nov.) We could not morphologically distinguish S. atlanticus sp. nov. from S. pacificus sp. nov., though they can be consistently delimited both geographically and with mitochondrial and nuclear DNA sequence data. We include information about the host plant legumes where the recognised species of Stenocorse and their associated bruchines were reared. A key to the recognised species of Stenocorse is provided.

Alphasida (Alphasida) perezveraisp. nov. is described from areas near El Ejido, in Almería province, South Eastern Spain. It is a one of the glabrous species in a subgenus where most taxa have a peculiar velvety pubescence on elytra. This new species correspond to A. geminaKoch, 1944, not available according to the Code (ICZN 1999) because being originally described as Alphasida lorcana ssp. mendizabali forma geminaKoch, 1944, an infrasubspecific name as a fourth name added to a trinomen. Habitus and aedeagus of the new species and its velvety “homologue” species A. mendizabaliKoch, 1944 are illustrated.
