Scapheremaeus luxtoni sp. n. is morphologically most similar to Scapheremaeus yamashitai Aoki, 1970, but differs from the latter by the morphology of notogastral and rostral setae, morphology of leg solenidia φ₂ and development of humeral processes. The species Scapheremaeus zephyrus Colloff, 2010 is recorded for the first time in New Zealand. An identification key to the known New Zealand species of Scapheremaeus is provided.     

Redescription of Mymarilla Westwood,new synonymies under Cremnomymar Ogloblin (Hymenoptera,Mymaridae) and discussion of unusual wings

The monotypic genus Mymarilla Westwood is known only from St. Helena, a remote island in the South Atlantic Ocean. The peculiar species M. wollastoni Westwood (Mymaridae) is redescribed and illustrated from non-type material. Mymarilla is compared with Cremnomymar Ogloblinspp. from the Juan Fernández Islands in the South Pacific Ocean. Stephanodes Enock is shown to be the most likely sister genus to Mymarilla. Nesopolynema Ogloblin, syn. n., Oncomymar Ogloblin, syn. n., Scolopsopteron Ogloblin, syn. n., are placed in synonymy under Cremnomymar and their species transferred as Cremnomymar caudatum (Ogloblin 1952), comb. n., C. dipteron (Ogloblin 1957), comb. n., and C. kuscheli (Ogloblin 1952), comb. n. Wing shape and wing reductions in Mymaridae are discussed in relation to biogeography, particularly with respect island faunas and to four genera, Cremnomymar, Mymarilla, Parapolynema Fidalgo, and Richteria Girault, some or all of whose species have more or less convex fore wings.     

Contributions to the knowledge of oribatid mites (Acari,Oribatida) of Indonesia. 3. The genus Galumna (Galumnidae) with description of a new subgenus and seven new species

Seven new species of oribatid mites of the genus Galumna are described from litter and soil materials of Sumatra, Indonesia. A new subgenus, Galumna (Atypicogalumna) subgen. n., is proposed; it differs from all galumnid genera and subgenera by the simultaneous presence of porose areas and sacculi on the notogaster (vs. either porose areas or sacculi present). Galumna (Galumna) calva Starý, 1997 is recorded for the first time in the Oriental region, and Galumna (Galumna) sabahna Mahunka, 1995 is recorded for the first time in the Indonesian fauna.     

Status of the enigmatic Oriental genus Rhithrogeniella Ulmer, 1939 (Ephemeroptera,Heptageniidae)

Based on historic collections and new material from Sumatra and Java, the species Rhithrogeniella ornata Ulmer, 1939, type species of the genus Rhithrogeniella, is reinvestigated. The nymph is described for the first time and is closely related to the continental Southeast Asian species Rhithrogeniella tonkinensis Soldán and Braasch, 1986. Rhithrogeniella belongs to the subfamily Ecdyonurinae, and is related to the genera Nixe Flowers, 1980 and/or Paracinygmula Bajkova, 1975 based on characters of the nymphal stage. Species described from Taiwan in the genus Nixe are transferred to the genus Rhithrogeniella: Rh. littoralis (Kang and Yang, 1994) comb. n., Rh. mitifica (Kang and Yang, 1994) comb. n. and Rh. obscura (Kang and Yang, 1994) comb. n.

Two new species of oribatid mites of the genus Lasiobelba (Oribatida, Oppiidae), Lasiobelba (Lasiobelba) daamsae sp. n. and Lasiobelba (Antennoppia) nepalica sp. n., are described from eastern Nepal. Lasiobelba (L.) daamsae sp. n. is most similar to L. (L.) remota Aoki, 1959 and L. (L.) gibbosa (Mahunka, 1985), however, it differs from both by the anterior part of pedotecta I specifically curved, rostrum pointed and exobothridial setae not shorter than bothridial setae. Lasiobelba (Antennoppia) nepalica sp. n. is most similar to L. (A.) granulata (Mahunka, 1986), however, it differs from the latter by the larger body size, exobothridial setae longer than rostral setae and bothridial setae not longer than interlamellar setae. An identification key to known species of Lasiobelba is given.

The ant genus Carebara Westwood (Hymenoptera,Formicidae): synonymisation of Pheidologeton Mayr under Carebara,establishment and revision of the C. polita species group

In this paper the genus Pheidologeton Mayr, 1862 is synonymized under Carebara Westwood, 1840 and the Carebara polita group is established and revised. This species group currently includes six species from the Afrotropical region (C. madibai, C. nicotianae, C. perpusilla, C. polita, C. silvestrii, and C. villiersi) and two species from the Neotropical region (C. brevipilosa and C. urichi). The polita group clearly links Carebara and Pheidologeton, and, due to a lack of autapomorphic characters for the latter, a separation of the two genera is no longer justified. As a result Carebara is presented as a monophyletic and better defined genus that can be separated from other genera with more confidence. We present an overview of the distribution and biology of Carebara as well as images from the various genera currently in synonymy under Carebara, and discuss the characters they share. The polymorphism present in Afrotropical and Malagasy Carebara is discussed and one new species from Africa, C. madibai sp. n., is described. The subspecies Carebara perpusilla arnoldiana syn. n., Carebara perpusilla concedens syn. n., and Carebara perpusilla spinosa syn. n. are new synonyms of Carebara perpusilla. Oligomyrmex politus nicotianae is re-elevated to species level and transferred into Carebara, C. nicotianae comb. n., stat. rev.; C. punctata is a new synonym of C. silvestrii comb. n. and C. pygmaea albipes comb. n., syn n., C. pygmaea bugnioni comb. n., syn. n., and C. simularensis syn. n. are new synonyms of C. pygmaea comb. n.. The following names are transferred from Pheidologeton to Carebara as new combinations (with the species epithets adjusted to female endings where necessary): aberrans, affinis, affinis javana, affinis minor, affinis spinosior, affinis sumatrensis, ceylonensis, dentiviris, diversa, diversa draco, diversa ficta, diversa laotina, diversa macgregori, diversa philippina, diversa standfussi, diversa taprobanae, diversa tenuirugosa, diversa williamsi, hammoniae, hostilis, kunensis, latinoda, maccus, mayri, melanocephala, melasolena, nana, nanningensis, obscura, petulens, pullata, pungens, pygmaea, rubra, rugiceps, rugosa, schossnicensis, silena, silvestrii, solitaria, transversalis, trechideros, varia, vespilla, volsellata, yanoi, and zengchengensis. Three new combinations are creating secondary junior homonyms and are here replaced with new names: C. mayri (Santschi, 1928) = C. gustavmayri nom. n., C. rugosa (Karavaiev, 1935) = C. rugoflabella nom. n., and C. silvestrii (Wheeler, 1929b) = C. luzonensis nom. n. Two new combinations are creating secondary junior homonyms among species already in Carebara: C. taprobanae (Forel, 1911a) = C. sinhala nom. n., and C. nana Santschi, 1919 = C. pumilia nom. n.     

Revision of three camaenid and one bradybaenid species (Gastropoda,Stylommatophora) from China based on morphological and molecular data,with description of a new bradybaenid subspecies from Inner Mongolia,China

We have revised the taxonomy of three camaenid and one bradybaenid species from China and described one new subspecies of the genus Bradybaena (Family Bradybaenidae) from Inner Mongolia, China. The genitalia of three Satsuma (Family Camaenidae) species S. mellea stenozona (Moellendorff, 1884), S. meridionalis (Moellendorff, 1884), comb. n. and S. uncopila (Heude, 1882), comb. n. assigned to the genus Bradybaena previously,lack a dart sac and mucous glands. Moreover, the molecular phylogeny has revealed close relationships between the three species and the genus Satsuma. Two species, S. stenozona (Moellendorff, 1884) from Fuzhou and Ganesella citrina Zilch, 1940 from Wuyi Mountain, are considered as synonymous and should be a subspecies of S. mellea mellea (Pfeiffer, 1866) because of the morphological and molecular similarities. Meanwhile, the other two are placed in the genus Satsuma: S. meridionalis (Moellendorff, 1884), comb. n. and S. uncopila (Heude, 1882), comb. n. G. virgo Pilsbry, 1927 differs from species of the genera Ganesella and Satsuma not only in its shell, but also in anatomical characters, such as having a dart sac and mucous gland, and lacking a flagellum. Additionally, phylogenetic analyses highly support the sister relationship with other Bradybaena species. Thus, placement of G. virgo Pilsbry, 1927 in the genus Bradybaena issuggested.     

Alocanthedon, a new subgenus of Chalicodoma from Southeast Asia (Hymenoptera, Megachilidae)

A new subgenus, Alocanthedon Engel and Gonzalez subgen. n., is described for five species of unusual Southeast Asian bees in the genus Chalicodoma Lepeletier de Saint Fargeau (Megachilinae: Megachilini). The subgenus is most noteworthy for the deep postgenal depression or furrow in males (bordered outwardly near the base of the mandible by a protuberant, thick lamella) and the presence of a dense patch of black setae posteriorly in the forewing medial cell (except in one species) [resembling the dense patch of setae among the submarginal cells of Thrinchostoma Saussure (Halictidae: Halictinae: Halictini)]. The subgenus is characterized and distinguished from the related Callomegachile Michener. A key to the following five species presently included in the subgenus is provided: Chalicodoma aterrimum (Smith), Chalicodoma atratiforme (Meade-Waldo) comb. n., Chalicodoma memecylonae Engel sp. n., Chalicodoma odontophorum Engel sp. n., and Chalicodoma apoicola Engel sp. n.Chalicodoma (Callomegachile) atratiforme sininsulae (Cockerell) is newly placed in synonymy with C. (C.) fulvipenne (Smith). Species have been collected from Memecylaceae (Myrtales) and Fabaceae (Fabales). The phylogenetic relationships of Alocanthedon among other Megachilini are briefly elaborated upon.     

A new genus and species of oribatid mite, <Emphasis Type="Italic">Cretaceobodes martinezae</Emphasis> gen. et sp. nov., from the lower cretaceous amber of San Just (Teruel Province,Spain) (Acariformes,Oribatida, Otocepheidae)

A new fossil genus and species of oribatid mite, Cretaceobodes martinezae gen. et sp. nov., belonging to the family Otocepheidae is described. The new species is preserved in a piece of amber from the San Just outcrop (Teruel Province, Spain), which is believed to be Albian in age. The new genus is compared with the extant genus Carabocepheus Berlese, 1910 and its relationships with the superfamilies Otocepheoidea and Carabodoidea are discussed. Carabocepheidae is regarded as a junior synonym of Otocepheidae. Ranking Carabocepheus lounsbury latior Balogh et Mahunka, 1966 as a separate species is proposed.

The lectotypes of Neoserica abnormis Moser, 1908 and the taxonomically uncertain N. inclinata Brenske, 1898, which very likely also belongs to this species group, are designated herein. A key to the species and to species groups is given, the genitalia of all species including their habitus are illustrated. Maps of species distribution are included.     

Two new species of oribatid mites of the family Galumnidae (Acari,Oribatida) from Vietnam

Two new species of oribatid mites of the family Galumnidae, Allogalumna monodactyla sp. n. and Galumna (Galumna) paracalcicola sp. n., are described from dark loamy soil under crown of Ficus sp. in southern Vietnam. Allogalumna monodactyla sp. n. is the first identified member of Allogalumna recorded for Vietnam. The identification keys to the species of Allogalumna from the Oriental region and species of Galumna (Galumna) from Vietnam and the calcicola-group are given.     

A new genus and species of Laelapidae from Iran with notes on Gymnolaelaps Berlese and Laelaspisella Marais & Loots (Acari,Mesostigmata)

Pogonolaelaps gen. n. a new genus of Laelapidae Berlese is erected and described based on Pogonolaelaps canestrinii (Berlese), comb. n. as well as on specimens which were collected from soil and ant nests in different parts of Iran. Also, a new species Pogonolaelaps beaulieui sp. n. is described based on specimens collected from soil, litter and ant nests in various parts of Chaharmahal va Bakhtiari province, Iran. The genus Gymnolaelaps is revised considering species with some morphological deviations. Gymnolaelaps reniculus (Karg, 1981) and Gymnolaelaps triquetrus (Karg, 2003) are removed from this genus and placed in their original genus Pseudoparasitus. The characters of Laelaspisella Marais & Loots, 1969 are discussed in a detail along with a proposal of a new definition.
