Two new species of Sensillonychiurus, are described from Changbai Mountains, northeastern China: S. reducta sp. nov. and S. pseudoreducta sp. nov. Both these species are very similar to each other, sharing such characters as a reduced unguiculus, 4 papillae and 3 guard chaetae on the Ant. III sensory organ, the AC type of labium, 5 5 chaetae on Th. I tergum, 9 distal tibiotarsal chaetae, as well as the absence of anal spines. Yet they can be differentiated by the presence vs. absence of pso on Th. I tergum, of chaetae p2 on Th. II tergum, and of chaetae b2 on the upper anal valve, respectively, as well as by the number of dorsal S-chaetae, of sublobal hair on the maxillary palp, of p-row chaetae on Abd. IV tergum.

A list of 18 species of the planthopper family Issidae known from Vietnam is given. Pseudochoutagus rubens sp. nov. is described from Northern Vietnam. New records for Macrodaruma pertinax Fennah, 1978 and Euxaldar jehucal Fennah, 1978 are provided. Convergence in body shape for the issid genera Pseudochoutagus Che, Zhang et Wang, 2011 and Choutagus Zhang, Wang et Che, 2006 and for the genus Philagra Stål, 1863 (Aphrophoridae) is mentioned for the first time.

A new species of the family Flatidae (Sisciini) Phlebopterum tapiae sp. nov. from Madagascar is described and illustrated. Additionally, environmental affinities of newly described species are discussed. A key to all Madagascan Phlebopterum Stål species is also provided.

A new species, Myrmica elbrusi sp. nov., is described from the North Caucasus (Kabardino-Balkaria, Russia). Its main diagnostic features are: the scape smoothly curved at the base, with no trace of lobe or carina; the frontal carinae very feebly curved, merging with the rugae that extend to the posterior margin, not curved outwards and not merged with the rugae surrounding antennal sockets; the frontal lobes not extended; the anterior clypeal margin distinctly prominent, narrowly rounded, not notched medially. Based on the above characters, M. elbrusi well differs from any other known Euro-Caucasian Myrmica species with smoothly curved scape [e.g. M. rubra (L.), M. ruginodis Nyl., M, gallienii Bondr., M. bergi Ruzs.], but fits well either to the rugosaor dshungarica species-groups (sensu Radchenko and Elmes 2010). Unfortunately, until males of M. elbrusi are found, this question cannot be resolved.

A new subgenus, Lophanthedon subg. nov., is described and figured for five species of distinctive Southeast Asian bees in the genus Chalicodoma Lepeletier de Saint Fargeau (Megachilinae: Megachilini). Two new species of the subgenus Pseudomegachile Friese from Africa, Chalicodoma, (Pseudomegachile) strangei sp. nov., and C. (P.) gibbsi sp. nov., and one of the subgenus Largella Pasteels from Malaysia, C. (Largella) donbakeri sp. nov., are described and figured. The subgenus Neochalicodoma Pasteels, consisting of the two African species C. pseudolaminata Pasteels and C. pseudocincta Pasteels, is synonymized with Pseudomegachile (syn. nov.). Chalicodoma pseudocincta, is newly placed in synonymy with C. (P.) scindularia (Buysson), syn. nov. The morphological diversity of Pseudomegachile is briefly discussed in an attempt to highlight useful characters for recognizing natural species groups and inferring floral hosts. Revised diagnoses as well as information on the species composition of Largella and Pseudomegachile are provided.

A new species Leptanilla lamellata is described from the north-west Shivalik region of India. Earlier the genus was represented by a single species viz., Leptanilla escheri (Kutter, 1948), which is here redescribed. A key to the known Oriental species of this genus is also provided.

The new extinct ant genus and species, Boltonidris mirabilis, are described from the late Eocene Rovno Amber (Ukraine). This genus belongs to the tribe Stenammini of the subfamily Myrmicinae. It possesses the plesiomorphic characters of the tribe Stenammini, e.g. 12-segmented antennae with 3-segmented apical club, characteristic structure of the clypeus and frontal lobes, absence of gastral shoulder, but it has a series of autapomorphies, e.g. modified mandibles with the only two teeth on the masticatory margin, well developed longitudinal medial groove on the head dorsum, somewhat depressed areas lateral to the frontal carinae (like “vestigial” antennal scrobes), and finely swollen postero-lateral area of head, close to the occipital corners. Additionally, it has two short blunt teeth on the pronotum.

The pupa and imago of Chironomus acerbiphilus (a senior synonym of C. crassimanus) show wide variation of external morphology characters. This paper describes the external morphology of larva, pupa and adult of C. acerbiphilus from Poland. Variability of morphological characters is evaluated for the Polish population in comparison with other European, Asian and North American populations. Pupal subgeneric characters are discussed.

Lygistorrhina caribbiana sp. nov. (Diptera: Lygistorrhinidae), the first fossil of this extant genus, is described from Dominican amber. All other fossil Lygistorrhinidae, which are known from older amber deposits in other regions, belong to extinct genera. This is the first fossil record of this rare family in Dominican amber and the first record for Hispaniola in general as the family is currently unknown from the extant fauna.

A catalogue of Chilean Elateridae is included with 11 subfamilies: Cebrioninae Latreille, Agrypninae Candèze, Lissominae Laporte, Semiotinae Jakobson, Campyloxeninae Costa, Pytiobiininae Hyslop, Dendrometrinae Gistel, Negastriinae Nakane and Kishii, Elaterinae Leach, Cardiophorinae Candèze, and Physodactylinae Lacordaire 1857, distributed in 52 genera and 140 species.

The Australian species classified in the cosmopolitan genus Scymnus are revised. Nomenclatural history, diagnoses, illustrations and distribution are provided for each of the eleven recognized species. Scymnus fuscatus Boheman, 1859 is recorded from Australia for the first time. Four new species, Scymnus alligator, S. bunya, S. leai and S. tasmanicus are described. Lectotypes are designated for: Midus pygmaeus Blackburn, 1892, Scymnomorpha duplopunctulata Blackburn, 1892, Scymnus ambulans Blackburn, 1895, S. mitior Blackburn, 1895, S. parallelus Blackburn, 1889, S. queenslandicus Blackburn, 1892 and S. varipes Blackburn, 1895. A new name Scymnus blackburni nom. nov. is introduced for Scymnus pygmaeus (Blackburn, 1892) preoccupied by Scymnus pygmaeus (Fourcroy, 1785). Scymnus varipes Blackburn, 1895 is recognised as a junior synonym of Scymnus ambulans Blackburn, 1895 (syn. nov.)

Henosepilachna, frusciantei, a new species from New Guinea is described and illustrated. It belongs to the group of species related to Henosepilachna vigintioctopunctata (Fabricius, 1775).

Species of Anisorcus Crotch are revised, diagnosed and illustrated. Notes on the genus and nomenclatural history for each species are provided. Lectotypes are designated for Anisorcus affinis Crotch and Anisorcus fryi Crotch. Anisorcus malayanus Crotch is recorded from Solomon Islands and Vanuatu for the first time. Keys to Australasian genera of Chilocorini and to Anisorcus species are presented.

Pentaphyllus reibnitzi sp. nov. from Cyprus is described, representing the fourth species of Pentaphyllus from the western Palaearctic Region. All four species from this area are figured, a key for their identification and selected faunistic data are given. Two species have a wider distribution in the western Palaearctic Region, and two are restricted to limited areas in Azerbaijan or Cyprus, respectively. The type specimens of the new species were found in polypores, collected from a dead tree of Ficus carica in an extensively cultivated garden near seashore. Lectotype of Pentaphyllus nitidulus Reitter, 1884 is designated.

The nomenclatural status of three darkling beetle species previously described under the name Helops gracilis, by Fisher von Waldheim in 1823, Küster in 1850 and Bland in 1864, is clarified. The status of a fourth species, a misidentification of Helops gracilis Küster by Allard (1876, 1877) and Seidlitz (1896), is also discussed. The following new nomenclatural acts are included: Helops gracilis Fisher von Waldheim in 1823 is recognized as Odocnemis (Heloponotus) gracilis (Fisher von Waldheim, 1823) comb. nov. (from Helops); Catomus kuesteri (Weise, 1878) comb. nov. (from Helops) is the valid name for Helops gracilis Küster, 1850; Helops blancli Bousquet and Bouchard, nom. nov. is proposed for Helops gracilis Bland, 1864. Odocnemis perplexus (Ménétriés, 1848) is considered a new synonym of Odocnemis gracilis (Fisher de Waldheim, 1823) and Catomus dichrous Reitter, 1902 as a new synonym of Catomus kuesteri (Weise, 1878). Lectotypes are designated for Helops gracilis Fischer von Waldheim, 1823, H. gracilis Bland, 1864 and H. seidlitzi Gebien, 1911.

Forty nine species of jumping spiders from the Calabar area in southeastern Nigeria and two from Kaduna Junction in central northern Nigeria are listed in this paper. Among these, the following 8 species are described as new to science: Bacelarella gibbosa sp. nov. (♂ ♀), Brancus lacrimosus sp. nov. (♂), “Brancus” nigeriensis sp. nov. (♀), Mexcala smaragdina sp. nov. (♂), Phintella paludosa sp. nov. (♂), Thiratoscirtus atakpa sp. nov. (♀), Thiratoscirtus efik sp. nov. (♂) and Thiratoscirtus procerus sp. nov. (♀). Females of Baryphas jullieni Simon, 1902, Longarenus brachycephalus Simon, 1903 and Thiratoscirtus torquatus Simon, 1903 are described for the first time. Two species names are synonymized, Schenkelia gertschi Berland et Millot, 1941 with Schenkelia modesta Lessert, 1927 and Myrmarachne insulana Roewer, 1942 with Myrmarachne hesperia (Simon, 1887). Four new combinations are proposed, Viciria mondoni Berland et Millot 1941, Viciria niveimana Simon, 1902 and Viciria peckhamorum Lessert, 1927 are transferred to the genus Brancus, and Mithion grassei Berland et Millot, 1941 is transferred to the genus Pseudicius. Twenty eight salticid species are recorded for the first time in Nigeria.

A new oribatid mite subgenus, Perscheloribates (Ecuadoribates) subgen. nov., and three new species, Perscheloribates (Ecuadoribates) pentasacculus sp. nov., Fissurobates neotropicus sp. nov. and Mucrobates microsetosus sp. nov., of the family Scheloribatidae are described from Ecuador. The new subgenus differs from Perscheloribates (Perscheloribates) by the number of notogastral sacculi and number of genital setae. Fissurobates and Mucrobates are recorded for the first time in Ecuador. The morphology of gnathosoma and legs are presented for the first time for any member of Fissurobates and Mucrobates.

The maturation, growth and reproduction of Alinda biplicata, in the laboratory were studied over a five-year period. The snails were kept in pairs and groups of a few individuals. The initial material came from two populations from SW. Poland. The snails reproduced during the whole year, more intensively in the spring and autumn. We confirmed the ovoviviparity of A. biplicata: the whole embrynic development takes place in eggs retained in the parent's uterus. The snails gave birth to juveniles (no egg-laying was observed), and the uteri of dissected individuals contained from 3 to 15 eggs. The number of juveniles per litter was 1 to 8. The snails produced 3 to 20 juveniles in 2–9 batches per year. The neonate shells had 2.1–2.9 whorls and height of 1–1.6 mm. Growth to adulthood lasted 20 to 56 weeks and the time increased with increasing density of snails. The snails became sexually mature 5–6 months after completeion of shell growth and formation of the closing apparatus. The juvenile mortality ranged from 16.7% to 60.6% and increased with density. The life span in the laboratory was 220 to 295 weeks (4 to 6 years). These results are compared with those for other species; A. biplicata resembles other large ovoviviparous Clausiliidae species.
