A review of the encyrtid wasp tribe Aenasiini,with descriptions of new Afrotropical taxa (Hymenoptera: Chalcidoidea)

The tetracnemine tribe Aenasiini is discussed and a key is provided for the separation of the nine genera that can be attributed to this tribe. Neodiscodes is synonymized with Aenasius and the following seven species, which were originally assigned to the former genus, are transferred to Aenasius as new combinations: abengouroui (Risbec), comperei (Kerrich), lepelleyi (Kerrich), martinii (Compere), indicus (Narayanan & Subba Rao), parvus (Kerrich) and subbaraoi (Kerrich). A key is given for the separation of the four Afrotropical species of Aenasius and the male of A. comperei is described for the first time. Incisencyrtus gen. n. is described for the following three new Afrotropical species: secus (the type-species), sirus and afer. Cladiscodes incisius sp. n. is described from South Africa and it represents the first species of this genus from Africa. New distribution records are given for three Alfrotropical species of Metaphaenodiscus.     

A review of the species of Neococcidencyrtus (Hymenoptera: Encyrtidae), parasites of diaspidid scale insects

A key is provided to the 18 known species of Neococcidencyrtus. Platylyca is synonymized with Neococcidencyrtus and its type-species, quadraticeps, is transferred to Neococcidencyrtus. The following species are described as new: brenhindis, cleddis, cliradainis, colynis, cullainis, delis, dryslydis, hynodis, melynis, selogis, synodis, and two further undescribed species are keyed but not formally described. All available published information on the biology and distribution of each species is listed and the pest status of the hosts is included.     

Two new species of Clinocentrus Haliday (Hymenoptera: Braconidae) from Argentina,with notes on South American species

The Argentine species of the genus Clinocentrus Haliday are revised. Two new species are described, Clinocentrus mamull sp. nov. and Clinocentrus roigi sp. nov., which represent the southernmost records of the genus in South America. Additionally Clinocentrus nigripectus Enderlein is redescribed and a key to known South American species is provided.     

A taxonomic and zoogeographical census of the extant ant taxa (Hymenoptera: Formicidae)

The numbers of extant ant taxa in the world are analysed taxonomically and zoogeographically. A table detailing numbers of subfamilies, tribes and genera, and the numbers of species they contain, and one analysing the number of species per genus per zoogeographical region, are presented. Subfamilies are analysed by number and percentage of genera and species; the most speciose genera are isolated and listed in terms of absolute size and speciosity per subfamily. Tables detailing total numbers of genera and species per subfamily per region, and endemic genera per subfamily per region are given, and the endemicity and speciosity of genera are tabulated on a regional basis.     

Partial revision of the Indo-Australian braconine wasp genus Gammabracon Quicke (Hymenoptera: Braconidae) with descriptions of new species from Indonesia (Mollucas), Malaysia,Philippines and Thailand

Ten distinctive new species of the taxonomically difficult braconine wasp genus Gammabracon Quicke, 1984 are described: G. apicoluteus sp. nov. from Malaysia (Negri); G. curticornis sp. nov. from Malaysia (Negri); G. philippinensis sp. nov. from the Philippines; G. siamensis sp. nov. from Thailand; G. striatus sp. nov. from West Malaysia; G. strandorum sp. nov. from Indonesia (Java), G. subvena sp. nov. from Malaysia (Negri and Sabah); G. townesorum sp. nov. from the Philippines; G. variipennis sp. nov. from Thailand; and G. wegeneri sp. nov. from Indonesia. Myosoma forticarinata Cameron, 1902 is transferred to Gammabracon, hence Gammabracon forticarinata comb. nov. A lectotype is designated for Gammabracon erythroura (Cameron). The status of Cratobracon strandiellus (Cameron) is discussed and a new combination proposed, Shelfordia strandiellus Cameron, 1910 comb. nov. (=Bracon strandiellus Cameron). Paucity of discrete morphological variation makes separation of most of the species with orange-red mesosoma, black metasoma and conspicuous back setae currently unrealistic and it may be that there is a single widespread and morphologically variable species.

Three new genera of Banchinae (Hymenoptera: Ichneumonidae) from Central and South America

Three new genera and four new species of Banchinae are described from Central and South America: Terrylee gen. n., is described from Peru and Honduras to accommodate Terrylee olearius sp. n. and Terrylee peruensis sp. n. (type species: Terrylee peruensis sp. n.); Valdiviglypta gen. n. and Pristiboea gen. n. are described from Chile (type species: Valdiviglypta nimbus sp. n. and Pristiboea leiomano sp. n.). Terrylee and Pristiboea are placed in the tribe Atrophini, Valdiviglypta tentatively in the tribe Glyptini. All the three new genera are morphologically very distinctive and two have such character suites that they may not immediately be recognizable as banchines. By describing these three Neotropical genera from Chile, Honduras and Peru we aim to draw further attention to the considerable morphological variation within the ichneumonid subfamily Banchinae.     

Insects associated with galls of a new species of Eurytomidae (Hymenoptera: Chalcidoidea) on Ephedra nebrodensis in Spain

Galls found on Ephedra nebrodensis in Spain are formed by a species of Eurytoma (Hymenoptera, Chalcidoidea, Eurytomidae) which is described as new. Four other species of Chalcidoidea (two described as new) and one species of Braconidae are parasitoids or inquilines of the eurytomid. An account is given of the biology of the community of insects associated with the gall.     

A new genus and species of Pteromalidae (Hymenoptera,Chalcidoidea) from Spain,parasitic in cynipid galls on Fumaria

Neaylax versicolor (Hymenoptera, Cynipidae), which forms galls on fumitory (Fumaria), is attacked in Spain by Rivasia fumariae, a species of Pteromalidae (Hymenoptera, Chalcidoidea) herein described as new and assigned to a new genus. The new genus has an unusual combination of morphological characters but seems best placed in the pteromalid subfamily Ormocerinae. An account is given of the biology and larval morphology of the new species.

Chelodesmid studies. XVIII. On some new or poorly-known taxa in the tribe Batodesmini (Polydesmida: Chelodesmidae)

Summary

Some new and poorly-known taxa of batodesmine diplopods are described from northern South America, with notes on their affinities. New genera include Igaraparana, based on I. batesi, sp. nov. from Amazonian Colombia; Curimagua, based on C. granulata, sp. nov. from Edo. Falcon, Venezuela; and Cheirogonus, based on C. pittieri, sp. nov. from Panama. The inadequately proposed species Leptodesmus interrupticolor Silvestri (southeastern Ecuador) is redescribed and figured from type material, and referred to Cordilleronomus as its third species. The enigmatic genus Tunochilus Chamberlin, 1950, is clarified and referred to the Batodesmini from its incorrect location in the Cryptodesmidae, with notes and drawings made from a paratype of the type species T. marginis; the presumptive congener T. marcuzzii is described as new from material taken at Caracas, Venezuela.     

New taxa of Rhagidiidae (Acari: Prostigmata) from North America. Part V. Genus Robustocheles Zacharda,with a key to world species of the genus

Six new species of rhagidiid mites from the Nearctic region, Robustocheles (R.) pascuaria n.sp., R. (R.) similis n.sp., R. (Mexia) longichelae n.subgen, n.sp., R. (Lewia) lacustris n. sp., R. (L.) obscuritata n. sp. and R. (L.) spinaea n. sp., are described. Additional morphological data are given for R. infernalis Zacharda and Elliott which is placed in the new subgenus Mexia. A key to adults of the known four subgenera and 15 species of the genus Robustocheles Zacharda of the world is presented.     

Two new taxa from the Lesser Sundas in the genus Onthophagus (Coleoptera: Scarabaeidae: Scarabaeinae)

Two new Indonesian taxa are proposed in Onthophagus Latreille, 1802, illustrating the composite faunal spectrum of the Lesser Sundas (Indonesia): O. montishannoniae, a new species from Flores, and O. accedens nusatenggaricus, a new subspecies from Lombok and Flores. O. accedens Lansberge, 1883 is, with O. dux Sharp, 1875, placed in what is here defined as the dux subgroup within the subgenus Parascatonomus Paulian, 1932. The three included species‐group taxa are keyed, their status is discussed, and new records are given. The position of O. montishannoniae seems taxonomically and geographically isolated: this species has no known close relatives in the region, neither in the Lesser Sundas, nor anywhere else in Wallacea.     

The taxonomy and biology of the British Adelognathinae (Hymenoptera: Ichneumonidae)

Summary

The known biology of Adelognathus, including new findings, is summarized. An illustrated key is given to the 15 species found in the British Isles. One species, A. stelfoxi, is described as new.     

Two new earthworm species from Belize (Oligochaeta: Acanthodrilidae)

In 2001 the Soil Biodiversity Group of the Natural History Museum, London collected Oligochaeta material from bromeliad epiphytes and litter samples in Belize. This material remained unidentified until being passed to the Annelida curator in 2010. Elaborating this material resulted in discovery of two earthworm species new to science Eutrigaster (Graffia) georgei sp. nov. and Kaxdrilus sherbutti sp. nov. belonging to the family Acanthodrilidae (Benhamiinae) and Acanthodrilidae (Acanthodrilinae) respectively. http://www.zoobank.org/urn:lsid:zoobank.org:pub:6BEB9E5A-7D54-4E48-913D-EF76D7DACC16

A character analysis of the North American potter wasps (Hymenoptera: Vespidae; Eumeninae)

A cladistic analysis of the nearctic genera of Eumeninae is presented. The ground plan states of 43 character systems are discussed, and the first comprehensive cladogram for any significant portion of the subfamily is presented. At least eight of the 26 genera are apparently nonmonophyletic: Zethus, Montezumia, Euodynerus, Odynerus, Pterocheilus, Stenodynerus, Leptochilus and Microdynerus. A key to the nearctic genera accompanies the text.     

On Paraclausenia gen. nov., Metapterencyrtus and Neocharitopus from India (Hymenoptera: Encyrtidae)

Swallowing sea water plays an important part in the process of egestion in several, epidermis-feeding, monogenean parasites from the skin and gills of fishes. In Entobdella soleae, from the skin of the common sole, Solea solea, the retracted pharynx acts as a peristaltic pump, forcing sea water into the branched and blind-ending intestine, inflating the gut diverticula and providing a suspension medium for debris from the digestive process. This secondary role for the pharynx has not previously been recorded. Inflation of the gut extends the muscles lying beneath the gastrodermis, and possibly neighbouring parenchymal muscles, permitting them to contract. This expels the sea water and flushes out the debris from the gut via the mouth. In E. soleae, the myofibrils associated with the gastrodermis appear to have narrower thick filaments than nearby parenchymal myofibrils. A similar series of swallowing movements, involving consecutive contractions of the pharynx followed by an egestion event, has been observed in the freshwater temnocephalan ectosymbiont Craspedella sp., from the gills of the Australian crayfish Cherax quadricarinatus.
