Some new and unrecorded Arrenurus Dugès 1834 (Acari: Hydrachnellae) species from Turkey

In this paper two new species, Arrenurus (s.str.) hasankalensis n.sp. and A. (s.str.) afyonensis n.sp., and the females of A. (s.str.) turgidus Koenike 1911 and A. (s.str.) ayyildizi Erman 1993 are described. In addition, a list of Arrenurus species known from Turkey is presented.     

Tanypodine midges of the genus Ablabesmyia Johannsen (Diptera: Chironomidae) from West Bengal with a note on their seasonal incidence and sex ratios

Summary

A key to the species of the subgenus Ablabesmyia occurring in India is provided. Four new species of Ablabesmyia, alba, ensiceps, maculitibialis and transversus are described. Systematic positions of paivai (Kieffer) and photophilus (Kieffer) in the genus are confirmed and is placed in the subgenus Karelia Roback previously unrecognised in the Oriental region. Seasonal incidence and sex ratio of some species are given.     

The female genitalia of Gonioctena,subgenus Spartoxena (Coleoptera: Chrysomelidae)

The taxonomy of the eight species of Gonioctena Chevrolat belonging to the subgenus Spartoxena Motschulsky is mostly based on male genitalia due to the unsuitability of external characters (i.e. coloration patterns) for identification. In order to provide similar diagnostic characters for both genders, the female genitalia of the eight species are described and illustrated. Considering the lack of spermathecae within the genus, the shapes of tergite 8, and sternites 8 and 9 have been explored as possible diagnostic characters. These structures present marked differences between taxa and simultaneously stability among individuals of each species, and thus they are very useful for taxonomic purposes. A key to the females of the subgenus Spartoxena is provided, and figures of tergite 9, and sternites 8 and 9 of each species are included.     

Variation in three centipede species of the genus Otostigmus and its bearing on species discrimination (Chilopoda; Scolopendromorpha; Scolopendridae)

Individual variation in populations of three species of the scolopendromorph centipede genus Otostigmus subgenus Otostigmus (O. spinicaudus (Newport, 1844), O. politus Karsch, 1881 and O. astenus (Kohlrausch, 1881)) is described and the reliability of their characters and those of other members of the subgenus is discussed.     

Description of two new species of Guernea (Crustacea,Amphipoda, Dexaminidae) from Japan,with tentative revision of subfamily Prophliantinae

Guernea minor sp. nov. and G. ezoensis sp. nov. are described from Japan. Based on these new species and the literature, a tentative revision of the subfamily Prophliantinae is proposed. The subgenus Prinassus of the genus Guernea is invalidated. The subgenus Haustoriopsis of the genus Guernea is re-elevated to a separate genus from Guernea. Dexaminoculus is transferred from Prophliantinae to Dexamininae.     

A new subgenus of the genus Colastes Haliday (Hymenoptera: Braconidae: Exothecinae) for species reared from bracket fungi,with description of two new species from Europe

A new Holarctic subgenus (Fungivenator subgen. nov.) of the genus Colastes Haliday, 1833 (Hymenoptera: Braconidae: Exothecinae) is proposed for a group of species that, as far as is known, has its larvae living on hosts in bracket fungi. The type species (Colastes sandei sp. nov. from Netherlands, Germany and England) and a second species (C. fritzeni sp. nov.) from Finland are described and illustrated. A key to the five known species is included.     

The immature stages of Simulium speculiventre,type-species of Stilboplax Enderlein (Diptera: Simuliidae)

Synopsis

The previously unknown immature stages of Simulium speculiventre are described and figured, and a lectotype is designated for this species from the adult syntypes. S. speculiventre is assigned to the subgenus Eusimulium (new subgeneric combination) and the genus-group name Stilboplax Enderlein is sunk in synonymy with Eusimulium Roubaud (new synonym).     

Predatory behaviour in Deltochilum: convergent evolution or a primitive character within a clade?

We present data on predatory behaviour in Deltochilum cupreicolle viridescens, which belongs to the subgenus Aganhyboma, and we contrast it with the behaviour of a species from the subgenus Deltohyboma. By this comparison we can investigate whether the predatory behaviour in Deltochilum could have appeared independently in these two subgenera, or if the behaviour is so similar that it suggests a single origin in a possible ancestor exclusive to those two groups. These laboratory studies on the behaviour of Deltochilum c. viridescens individuals on diplopods are described and divided into the following stages: (1) approach and recognition of the diplopod; (2) attack and death of the prey; (3) on-site feeding; (4) transport of the diplopod. The results found here strengthen the hypothesis of a primitive and highly specialized behaviour within a possible clade formed by the predatory species of Diplopoda.     

Water mites of the family Hygrobatidae Koch from southern Africa (Acari: Hydrachnidia)

New records are given of the water mite family Hygrobatidae (without the genus Atractides) from southern Africa (South Africa, Botswana, Namibia). In addition to one new subgenus of the genus Hygrobates, namely Inflatibates, four new species are described, namely Hygrobates draconicus, H. laceratoides, H. okavangoensis, and H. inflatipes as well as one new subspecies, namely Hygrobates spathuliferus cederberg. The following synonyms are established: the subgenus Capobates Thor with Hygrobates Koch, Hygrobates sanguineus transvaalensis K. O. Viets with Hygrobates spathuliferus (Lundblad), and Ambiguobates permixtus agnewi K. O. Viets with Ambiguobates permixtus K. Viets. The male of Australiobates pilosus (K. Viets) is described for the first time. The synonymization of Diversibates with Australiobates can now be confirmed. Finally, keys are given for the known genera of southern Africa, as well as for all known species of the genus Hygrobates from southern Africa.     

The flower bug genus Orius Wolff, 1811 (Hemiptera: Heteroptera: Anthocoridae: Oriini) of Thailand

The flower bug genus Orius Wolff, 1811 (Hemiptera: Heteroptera: Anthocoridae: Oriini) in Thailand is reviewed. Eleven valid species are recognised; seven of them are described as new to science: Orius (O.) sakaerat, O. (O.) taksini, O. (O.) tomokunii, O. (O.) filiferus, O. (O.) machaerus, O. (O.) inthanonus and O. (Trichorius) crassus. Orius (Heterorius) dravidiensis Muraleedharan, 1977, which has been known from India, is recorded from Thailand for the first time, and is correctly placed in the subgenus Dimorphella Reuter, 1884. The subgenus Paraorius Yasunaga and Miyamoto, 1993 is proposed as a synonym of Dimorphella. Diagnoses, digital habitus images, scanning electron micrographs and illustrations of diagnostic features including both male and female genitalia are provided. Keys to the Thai species are offered to facilitate identification. Biology of Thai species is also discussed.     

Descriptions of the Patagonian species of the subgenus Trichohelea of Forcipomyia,with a key to the Neotropical species (Diptera: Ceratopogonidae)

The following two new species of Forcipomyia (Trichohelea) collected in the Nothofagus patagonian forest are described and illustrated: F. (T.) sayhuequei from the province of Chubut in Argentina and Llanquihue in Chile, and F. (T.) tehuelche from the Argentinean province of Santa Cruz. Based on the examination of the types, the previously known species Lasiohelea shannoni Ingram and Macfie is recognized as a junior synonym of Forcipomyia limnetis Ingram and Macfie, and the species is redescribed and illustrated. A key to recognition of females and males of the 14 Neotropical species of the subgenus is included.     

Taxonomy and cladistic analysis of the subgenus Xenomorellia Malloch (Diptera: Muscidae: Morellia Robineau-Desvoidy) with description of two new species

Xenomorellia Malloch, a subgenus of Morellia Robineau-Desvoidy, is revised to include two new species, Morellia (Xenomorellia) inca Nihei and Carvalho sp. nov. from South America, and M. (X.) maia Carvalho and Nihei sp. nov. from Costa Rica and Mexico. Diagnoses for M. (X.) holti (Malloch) and M. (X.) montanhesa (Albuquerque) are provided, as well as an identification key to the four species of the subgenus. A cladistic analysis was performed to test the monophyly of Xenomorellia and to recover the phylogenetic relationships among its species. Tree searches resulted in one single most-parsimonious cladogram, wherein the monophyly of Xenomorellia is supported, as well as a sister-group relationship with the Neotropical subgenus Trichomorellia Stein. Xenomorellia was divided into two clades: one with Caribbean–Andean species (maia?+?inca), and another with species from southeastern South America (holti?+?montanhesa).     

New species of Isometopinae (Hemiptera: Miridae) from the Ivory Coast and Yemen

Myiomma cobbeni n. sp. and Paloniella nodifrons n. sp. are described from the Ivory Coast. Additionally, M. maculata n. sp., Isometopus yemenensis n. sp. and I. quadrivittatus n. sp. are described from the Republic of Yemen. The new species from Yemen represent the first records of Myiomma Puton and the subgenus Jehania Distant of Isometopus Fieber from the Middle East.     

A key to Neodohrniphora (Diptera: Phoridae), parasites of leaf-cutter ants (Hymenoptera: Formicidae)

A key to the females of Neodohrniphora Malloch is provided. A species referred to as Apocephalus sp. by Eibl-Eibesfeldt and Eibl-Eibesfeldt (1967) is assigned to N. attae sp. nov., and to a newly designated subgenus Eibesfeldtphora for the N. curvinervis (Malloch) group of species. Neodohrniphora frontalis (Curran) is confirmed as a synonym of N. (E). curvinervis. The paratype of N. (N.) acromyrmecis Borgmeier differs from the lectotype, and is reassigned to N. (N.) similis Prado. A new subgenus, Wallerphora, is designated for N. (W.) mexicanae sp. nov. from Mexico.     

Palaearctic species of Ammoplanus (Hymenoptera: Sphecidae)

The Palaearctic species of the genus Ammoplanus Giraud are revised, based on material of over 1750 specimens from Europe, North Africa and Central Asia. For almost all species it was possible to examine the type material and in six species the lectotypes have been designated, in two cases (A. perrisi and A. marathroicus) the neotypes. As a result 38 species are recognized as valid, keyed out and commented on. Eight species are described as new and four species names are here placed in synonymy. Several species are of wide distribution, which made it necessary to include also those described from Central Asia and Mongolia. The keys are made to all Palaearctic species but no material is known from the regions east of Mongolia, although four undescribed species are available from South-East Asia. The Afrotropical species are listed and most of them were also examined. Two subgenera are recognized in the region; 32 species are classified in Ammoplanus sensu stricto and six in the subgenus Ammoplanellus. In the nominal subgenus the following species are described as new: A. atlasensis from Morocco, A. biscopula from Israel, A. biskrensis from Algeria, A. denesi from Turkey (Anatolia), A. freidbergi and A. kaplanae from Israel, A. minutus from Bulgaria and Turkey and A. strumae from Bulgaria and Greece. New synonymy: A. angelae becomes a junior synonym of rhodesianus (known before only from Africa), A. crudelis a synonym of A. kaszabi, A. handlirschi a synonym of A. marathroicus, A. suarezi a synonym of A. kohlii, A. subcompressus of A. gegen, A. orbiculatus of A. simplex and A. zarcoi of A. kohlii; A. wesmaeli is confirmed as a synonym of A. perrisi. Otherwise the synonymy is corrected under A. bischoffi and the names A. dusmeti and A. curvidens are re-established as valid. In a short review of the African species A. (Ammoplanellus) cradockensis Arnold, 1959 is placed as a new synonym under A. (Ammoplanellus) latiscapus Leclercq, 1959. The nomenclatural changes are explained under the relevant species.     

Taxonomic notes on the Asian frogs of the tribe Paini (Ranidae,Dicroglossinae): 1. Morphology and synonymy of Chaparana aenea (Smith, 1922), with proposal of a new statistical method for testing homogeneity of small samples

The species from northern Vietnam described as Rana fansipani Bourret, is shown to be a synonym of the species from northern Thailand described as Rana aenea Smith, . The male secondary sex characters of this species are described in detail for the first time. Combined with a few other characters, they allow this species to be distinguished from the closely related Rana unculuanus Liu, Hu and Yang, 1960 from southern China. Both species should be placed in a subgenus Chaparana (Chaparana), a member of the tribe Paini of the subfamily Dicroglossinae of the Ranidae. In this study, we propose a new statistical method for testing homogeneity of small samples: this consists of considering the values obtained for each specimen and for each regression factor score as morphometric characteristics of this specimen within the frame of this analysis; these values, or some of them, can be used to compare subgroups of specimens by non‐parametric tests such as the Mann–Whitney U test.
