(L.) trimaculatus (Hermann, 1804), Valgothrombium mallorcensis (Haitlinger, 2003) comb. n., Podothrombium proti Haitlinger, 1994 is not synonym of P. filipes (C.-L. Koch, 1837).     

Revision of the larvae of Leptus Latreille (Acarina: Erythraeidae) of Europe and North America, with descriptions of post-larval instars

The larvae of Leptus Latreille, 1796 (Acarina: Erythraeidae) of Europe and North America are comprehensively revised. Of those described since 1900 a total of 34 species is considered recognizable and capable of being keyed; no species described before 1900 is considered recognizable. The nominal type of the genus, Acarus phalangii de Geer, 1778 is rejected as an illegitimate name. Eighteen European and 17 North American species are described and keyed, of which 17 are new to science. One new subspecies from North America, of a species previously known from Europe, is described and keyed. Standard metric data are given for each species or subspecies from available specimens (except two North American species, L. ariel Southcott and L. clarki Southcott, recently described elsewhere; for these last-named two additional metric data are given). Larvae have been recorded from April to September, with the greatest number found being for July and August.
Protonymphs are described for two North American species ( L. ghiradellae sp. nov. and L. welbourni sp. nov. ), and deutonymphs for two North American species ( L. calix sp. nov. and L. ghiradellae ). Keys are given to separate the reared protonymphs, and three described deutonymphs (the two preceding and the European L. galerucae Feider). Data on the duration of the protonymphal instar suggest that in North America and Europe there are two modes: one lasting 3–4 weeks, the other 5–7 months. Developmental abnormalities are recorded systematically.

Teratological abnormalities are recorded for L. cultellus, L. fisheri, L, minno and L. urodaci.     

New Spiroplasma in parasitic Leptus mites and their Agathemera walking stick hosts from Argentina

Here we report the presence of Spiroplasma 16S rRNA in populations of two parasitic Leptus mites (Leptus sayi; Leptus lomani) and their Agathemera walking stick hosts. In walking sticks Spiroplasmas were detected in the gut, as well as muscle-tissues, but not in eggs. Throughout Argentina 15.4% of L. sayi populations and 14.3% of L. lomani populations surveyed screened positive for Spiroplasma. Phylogenetic analyses (ML, BCMC) place all sequences within the Ixodetis group. Most sequences form a well-supported sister subclade to the rest of Ixodetis. We briefly discuss the role of Leptus mites in the natural transmission of Spiroplasma.

The new species are placed in their appropriate groups and differentiated from the other species in the group.     

Three new Leuctra Species from Tunisia (Plecoptera: Leuctridae)

Three new Leuctra species, L. khroumiriensis sp. n., L. sartorii sp. n. and L. medjerdensis sp. n., from Tunisia, are described. They share a close morphological relationship with two other species of the hippopus group, L. occitana Despax and L. vaillanti Aubert, which are redescribed. L. occitana is redescribed from material collected in Southern Spain, and L. vaillanti from Moroccan and Tunisian material, constituting the first record for Tunisia.     

Seven new species and two new subspecies of Sclerocypris SARS, 1924 from Africa,with new records of some other Megalocypridinids (Crustacea,Ostracoda)

Sclerocypris dayae n.sp., S. dedeckkeri n.sp., S. dumonti n.sp., S. zelaznyi n.sp. and S. zelaznyi etoshensis n.ssp. are described from South — West Africa (Namibia). S. exserta makarikarensis n.ssp. originates from the endorheic pan system Makarikari in Botswana. S. woutersi n.sp. was described from Lake Albert where it is quite common. S. virungensis n.sp. is known from the Virunga National Park, south of Lake Edward (Zaire). The latter two species are closely related and from part of the flabella-species group. S. longisetosa n.sp., described from a marsh near Kisumu (Kenya), is an enigmatic species, holding an isolated position in the genus due to an aberrant T1.Present address: Rijksuniversiteit Gent, Laboratorium voor ecologie der dieren, zoögeografte en natuurbehoud (Institute for Ecology), K. L. Ledeganckstraat 35, B9000 Gent, Belgium.     

Three new species from the subfamily Phyllocoptinae (Acari,Trombidiformes, Eriophyidae) in Iran

Three new eriophyid species (Phyllocoptinae), Shevtchenkella denticulata sp. n., Notallus pestehae sp. n. and Echinacrus ruthenicus sp. n., were described from Eryngium thyrsoideum Boiss. (Apiaceae), Pistacia vera L. (Anacardiaceae) and Lycium ruthenicum Murray (Solanaceae), respectively. All the three new species were collected from southwest of the East Azerbaijan province, Iran in 2011. It is the first record of an eriophyoid mite collected from E. thyrsoideum and L. ruthenicum and the first record of Notallus from Anacardiaceae plant family.     

The marine Tubificidae (Oligochaeta) of the barrier reef ecosystems at Carrie Bow Cay, Belize, and other parts of the Caribbean Sea, with descriptions of twenty-seven new species and revision of Heterodrilus, Thalassodrilides and Smithsonidrilus

Fifty-nine species of Tubifieidae are recorded from Belize on the Caribbean side of Central America. Twenty-five are new to science: Ainudrilus geminus sp.n., Heronidrilus gravidus sp.n., Heterodrilus flexuosus sp.n., H. ranus sp.n., H. modestus sp.n., Coralliodrilus rugosus sp.n., C. randyi sp.n., Phallodrilus compactus sp. n., P. singularis sp.n., P. vicinus sp.n., P. nasutus sp.n., P. bipartitus sp.n., Inanidrilus reginae sp.n., Olavius finitimus sp.n., O. vacuus sp.n., O. (Olavius) pravus sp.n., Bathydrilus vetustus sp.n., B. egenus sp.n., Thalassodrilides bruneti sp.n., Limnodriloides anxius sp.n., L. major sp.n., L. sacculus sp.n., L. adversus sp.n., Smithsonidrilus appositus sp.n., S. involutus sp.n. Phylogenetic analyses indicate that Heterodrilus Pierantoni, 1902, Thalassodrilides Brinkhurst & Baker, 1979, and Marcusaedrilus Righi & Kanner, 1979, are paraphyletic taxa as previously defined. They are therefore revised to include also apomorphic species earlier attributed to separate genera; in so doing, Marcusaedrilus becomes a junior synonym of Smithsonidrilus Brinkhurst, 1966. Smithsonidrilus pauper sp.n. (Peru), and S. multiglandularis sp.n. (Florida and Puerto Rico) are also described, and Limnodriloides claviger Erséus, 1982 is regarded as a synonym of L. pierantonii (Hrabě, 1971).     

Three new species of mites (Acari: Prostigmata: Erythraeidae) from the Republic of Cape Verde

Leptus (Leptus) salicus sp. n. collected from unidentified Orthoptera, L. (L.) korneli sp. n. and Erythraeus (Erythraeus) capeverdensis sp. n. both collected from herbaceous plants from the Republic of Cape Verde are described.     

Attachment Sites and Frequency Distribution of Erythraeid Mites, Leptus Indianensis (Acari: Prostigmata), Ectoparasitic on Harvestmen, Leiobunum Formosum (Opiliones)

Host attachment sites and frequency distribution of parasitism were investigated for the larval erythraeid mite Leptus indianensis parasitising a sample of 500 harvestmen, Leiobunum formosum in Tennessee, USA. A significant difference was found in the number of mites attached to different body segments of the harvestmen with the greatest number of mites attached to femurs I–IV. Scanning electron microscopy revealed that the mites attached to smooth areas of the host integument between rows of stout setae. The frequency distribution of mites parasitising the harvestman population was highly clumped (Coefficient of Dispersion=3.34) with a relatively small number of hosts being parasitised by most of the mites.     

Ten new species of Haliotrema (Monogenoidea: Dactylogyridae) from Australian fish and a revision of the genus

Ten new species of Haliotrema from Australian fish are described and figured: H. cteno-chaeti sp. n. from Ctenochaetus strigosus; H. falcanalis sp. n. from Triacanthus falcanalis; H. lineate sp. n. from Acanthurus lineatus; H. chrysotaeniae sp. n. from Lutjanuschrysotaenia; H. cromileptis sp. n. from Cromileptis altivelis; H. epinepheli sp. n. from Epinephelus merra and E. fasciatus; H. holocentri sp. n. from Holocentrus ruber; Haliotrema chrysostomi sp. n. from Lethrinus chrysostomus and Plectorhinchus pictus; H. fleti sp. n. n. from L. fletus and L. chrysostomus; H. scari sp. N. from Scarus fasciatus.

H. brevis (Mizelle & Price, 1964) comb, n. , H. canescens (Mizelle & Price, 1964) comb. n. and H. zanclus (Mizelle & Price, 1964) comb. n. are transferred from Pseudohaliotrema Yamaguti, 1953; H. eilatica (Paperna, 1965) comb. n. , H. teuthis (MacCallum, 1915) comb. n. , H. triacantha (Tripathi, 1959) comb. n. and H. lethrini (Yamaguti, 1937) comb. n. are transferred from Ancyrocephalus Creplin, 1839.
The generic diagnosis is emended to include the above-mentioned species and the taxonomy of the genus is discussed and the formation of six species groups is proposed.     

Six new species of Lepidapedon Stafford, 1904 (Digenea: Lepocreadiidae) from deep-sea macrourid fishes from the Gulf of Mexico and Caribbean Sea, with revised keys to the species of the genus

Species of the genus Lepidapedon are divided into various groups and subgroups based on vitelline distribution relative to the acetabulum and anterior extent of the excretory vesicle. Members of this genus predominantly parasitise gadiform fishes and are commonly collected from relatively deep waters. A recent study of deep-sea helminths from macrourids of the Gulf of Mexico and Caribbean Sea revealed six new species of this genus. L. mexicanensis n. sp., of the elongatum group, elongatum subgroup, differs from other species in this subgroup in proportions (as % of body length), lacking confluent vitelline fields between both the ovary and anterior testis and the testes, and in having a smaller egg and body size. L. nezumiatis n. sp., of the elongatum group, desclersae subgroup, differs from both L. filiformis and L. desclersae in having intermediate egg and body sizes, and a longer oesophagus than prepharynx. L. caribbaei n. sp. and L. longivesicula n. sp., of the garrardi group, congeri subgroup, differ from L. congeri in having a sucker-ratio of 1:<1. L. caribbaei n. sp. and L. longivesicula n. sp. differ from each other in that L. caribbaei n. sp. has numerous long, barb-like, deeply imbedded spines, a less elongate body, an infundibuliform oral sucker, a similar-sized oesophagus and prepharynx, and a caecal bifurcation which is closer to the acetabulum than oral sucker, while L. longivesicula n. sp. has shorter, serrate or plate-like, lightly imbedded, widely to sporadically spaced spines, a more elongate body, a spherical to subspherical oral sucker, a longer oesophagus than prepharynx, and a caecal bifurcation which is closer to the oral sucker than acetabulum. L. desotoensis n. sp., of the rachion group, rachion subgroup, is distinct from both L. luteum and L. abyssensis in having a smaller size, lacking cervical glands or pharyngeal gland cells, and possessing dark-staining particles in the mesenchyme, while it differs from L. abyssensis specifically in having a much longer oesophagus than prepharynx, lateral vitelline fields that are not confluent intertesticularly, and wider eggs. L. zaniophori n. sp., also of the rachion subgroup, differs from both L. cascadensis and L. genge in having a smaller egg size, a shorter prepharynx and oesophagus than pharynx, and vitelline fields that are intertesticular but only slightly encroach between the ovary and anterior testis. L. sammari and L. spiniferi are designated as incertae sedis, and L. quiloni and L. stromateusi are designated as species inquirendae. New parasite keys and host records for Coelorinchus coelorhincus, C. caribbaeus and Nezumia cyrano are offered. Support is given to Lepidapedon probably being the dominant digenean genus in deep water.
