The endophallic structure of the genus Laius is studied and discussed based on the examination of 19 species from Asia to the Indian Ocean. The structure contains two primary sclerites (named gonoporal piece and ligula), a secondary sclerite on the basal part of the gonoporal piece (named additional sclerite) in some species, and a membranous basal area closely covered with many spines (named spinous area). Five species groups are recognized based on the morphology of the endophallic sclerites. The sympatric species have different body sizes and quite distinguishable endophallic sclerites (= different species group), while the allopatric species have overlapping body sizes and similar endophallic sclerites (= same species group). Three new species are described and six previously known species are redescribed with endophallic sclerites, and the descriptions of endophallic sclerites of the remaining ten species are added. The larva of Laius rodriguesensis sp. nov. is also described. The genus
Nossibeus Evers, 1994 is synonymised with Laius Guérin-Méneville, 1830.

The taxonomy of the family Desmodoridae (Nematoda: Desmodorida) is partially revised based on morphology. The diagnoses of the Desmodoridae and the subfamilies Desmodorinae and Spiriniinae are emended to accommodate re-analyzed morphological features. Eight known species are redescribed and the implication of the new findings for the taxonomy of the group is discussed. Amphispira and Metadesmodora are confirmed as genera inquirendae. Alaimonema and Sigmophoranema, and their corresponding type species, are proposed as inquirendae due to poor descriptions of the type material. The other three species of Sigmophoranema are transferred to the genus Onyx because they bear the diagnostic features of this group: spear-like dorsal tooth and s-shape precloacal supplements. Echinodesmodora, Paradesmodora and Stygodesmodora are transferred to the Spiriniinae based on the absence of a head capsule and on the amphidial fovea being surrounded by cuticle striation. Paradesmodora toreutes is transferred to the genus Acanthopharyngoides as A. toreutes comb. nov. The genus Onepunema does not fit in the family Desmodoridae because of diorchic males; thus, it is regarded as taxon incertae sedis.
Lists of valid genera for the two subfamilies are provided. A dichotomic key for the identification of the 14 genera within the Spiriinae is provided.

The South African endemic bees of the "euryglossiform" species of the genus Scrapter Lepeletier & Serville, 1828 are revised and illustrated. The species-group is defined for the first time and comprises 20 species, 16 of which are described here as new: Scrapter exiguus sp. nov. ♀, ♂, S. gessorum sp. nov. ♀, S. inexpectatus sp. nov. ♀, S. luteistigma sp. nov. ♀, ♂, S. minutissimus sp. nov. ♂, S. minutuloides sp. nov. ♀, S. minutus sp. nov. ♀, S. nanus sp. nov. ♀, ♂, S. nigerrimus sp. nov. ♀, S. nigritarsis sp. nov. ♀, S. papkuilsi sp. nov. ♀, ♂, S. punctatus sp. nov. ♀, ♂, S. pygmaeus sp. nov. ♀, S. roggeveldi sp. nov. ♀, ♂, S. spinipes sp. nov. ♀, ♂ and S. ulrikae sp. nov. ♀, ♂. For S. acanthophorus Davies, 2005 and S. sittybon Davies, 2005 the female is here described for the first time. A key to all species is provided.

The Afrotropical Rhyssinae are reviewed. A total of 12 species are reported from the region, including five new species: Epirhyssa brianfisheri sp. nov., E. gavinbroadi sp. nov., E. shaka sp. nov., E. villemantae sp. nov. and E. tombeaodiba sp. nov. The generic status of E. brianfisheri sp. nov. is discussed since this species could also be considered to be an extra-limital Triancyra species, emphasizing the putative paraphyletic status of Epirhyssa. Epirhyssa ghesquierei Seyrig, 1937, E. overlaeti Seyrig, 1937 and E. uelensis Benoit, 1951 are newly reported from Cameroon. We provide illustrated diagnoses and identification notes. Finally, we discuss the apparent scarcity of African rhyssines compared to other regions.

This study presents a taxonomic update of the Tetramorium weitzeckeri species group.
Tetramorium mpala sp. nov. is described from Laikipia, Kenya, and placed in the T. weitzeckeri species complex. In addition, we also provide an illustrated identification key to the three species complexes of the T. weitzeckeri species group, and an updated illustrated identification key to the species of the T. weitzeckeri species complex.

Populations of Stegelleta are described from California, New Zealand and Senegal. An amphimictic population from California is identified as belonging to S. incisa and compared with type specimens from Utah and an amphimictic population from Italy. One population from New Zealand is close to S. incisa but considered to represent a new species, Stegelleta laterocornuta sp. nov. It is particularly characterised by a 379–512 μm long body in females and 365–476 μm in males; cuticle divided into 16 rows of blocks at midbody (excluding lateral field); lateral field with four incisures; three pairs of asymmetrical lips, U-shaped primary axils without guarding processes, each lip asymmetrically rectangular with a smooth margin, only lateral lips have slender acute tines; three labial probolae, bifurcated at half of their length; vulva without flap; spermatheca 17–31 μm long; postuterine sac 7–24 μm long; spicules 21.5–23.5 μm long. Other specimens from New Zealand are identified as belonging to S. tuarua. A parthenogenetic population from Senegal is identified as belonging to S. ophioglossa and compared with type specimens from Mongolia and records of several other populations of S. ophioglossa. The generic diagnosis is emended and a key to the species of Stegelleta is provided.

Kempfidris : a new genus of myrmicine ants from the Neotropical region (Hymenoptera: Formicidae)
(2014)
The new genus Kempfidris gen. nov. is described based on the workers of a single species, K. inusualis comb. nov., from Brazil, Ecuador, and Venezuela. Kempfidris inusualis comb. nov. was originally described by Fernández (2007) and provisionally placed in Monomorium awaiting a better understanding of the internal relationships in Myrmicinae. Kempfidris gen. nov. has a series of distinctive morphological characters including the mandibular configuration, vestibulate propodeal spiracle, propodeal carinae, and cylindrical micro-pegs on the posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII. This last trait appears to be autapomorphic for the genus.

This paper summarizes current knowledge about Central African pholcids. Central Africa is here defined as the area between 10°N and 7°S and between 6°E and 18°E, including mainly the Lower Guinean subregion of the Guineo-Congolian center of endemism. This includes all of Gabon, Equatorial Guinea, São Tomé and Príncipe, most of Cameroon and Congo Republic, and parts of the neighboring countries. An annotated list of the 14 genera and 79 species recorded from this area is given, together with distribution maps and an identification key to genera. Seven species are newly described: Anansus kamwai sp. nov., Leptopholcus gabonicus sp. nov., Ninetis faro sp. nov., Pholcus punu sp. nov., P. rawiriae sp. nov., Spermophora abibae sp. nov., and S. awalai sp. nov. Additional new records are given for 16 previously described species, including 17 new country records. Distribution and diversity patterns are compared with data on West and East Africa. While West Africa contains a similar set of genera it is significantly less diverse than Central Africa. East Africa is taxonomically more distinct. It has similar levels of diversity as Central Africa, but appears to be less undersampled.
