Sinharaja gen. n., a new Uropodina mite genus from Sri Lanka with description of two new species (Acari: Mesostigmata: Uropodidae)

A new Uropodina genus (Sinharaja gen. n.) is described on the basis of two new species (S. ceylonensis sp. n. and S. sinhala sp. n.) from Sri Lanka. The new genus differs by the strongly sclerotised dorsal lines, pentagonal pygidial shield, the shape and length of dorsal setae and the shape of first and fourth hypstomal setae, internal malae and epistome from the other known Uropodina genera.     

Eriorhynchidae, a new family of Prostigmata (Acarina), with a cladistic analysis of eupodoid species of Australia and New Zealand

A new family of eupodine Prostigmata, Eriorhynchidae fam.n. , is established to accommodate Eriorhynchus gen.n. , and five species from Australia: E.australicus (Womersley), E.hades sp.n. , E.ramosus sp.n. , E.walteri sp.n. and E.womersleyi sp.n. The new family is unique in the possession of 15–34 setae on the gnathosomatic base, a naso-prodorsal process with 9–28 setae and a palp tibia with 6 or 7 setae. A key to the families of Eupodoidea is provided. A cladistic analysis of twenty-seven eupodoid species from Australia and New Zealand is presented. Results indicate that the genus Eriorhynchus gen.n. (thus Eriorhynchidae) is monophyletic, and the Australian and New Zealand species of Halotydeus Berlese, Penthaleus C. L. Koch, Rhagidia Thorell and Stereotydeus Berlese form separate monophyletic goups, while the Penthaleidae are not monophyletic. The new family Eriorhynchidae is a sister group to a clade consisting of Penthaleus and Chromotydaeus quartus Qin & Halliday.     

A new oribatid mite of the genus Rhynchoribates (Acari,Rhynchoribatidae) from equador

A new oribatid mite species, Rhynchoribates parafabulosus sp. n., is described from Ecuador. This species is similar to R. fabulosus Beck 1961 (from Peru) in the rostrum structure and the length of prodorsal and notogastral setae. However, it clearly differs from the above species by the absence of thorns on the leg femora, location of adanal lyrifissures, and the structure of notogastral setae.     

New Quill Mites of the Family Syringophilidae (Acari: Cheyletoidea)

Five new species and two new genera belonging to the family Syringophilidae (Acari: Cheyletoidea) are described from birds that died in the Antwerp Zoo during their quarantine: Charadriaulobia vanelli n. g., n. sp. from Vanellus chilensis (Charadriiformes: Charadriidae) in Brazil; Fritschisyringophilus lonchurae n. g., n. sp. from Lonchura punctulata (Passeriformes: Estrildidae) in India; Mironovia coturnae n. sp. from Coturnix coturnix (Galliformes: Phasianidae) in Europe; Syringophiloidus daberti n. sp. from Passerina ciris (Passeriformes: Emberizidae) in Mexico; and S. serini n. sp. from Serinus mozambicus (Passeriformes: Fringillidae) in Central Africa. Charadriaulobia n. g. differs from the closely related Aulobia Kethley, 1970, in both sexes, by the divergent epimeres I; in females, by the absence of protuberances on the hypostomal apex and by the situation of the bases of setae l4 distinctly anterior the bases of setae d4. Fritschisyringophilus n. g. differs from the closely related Syringophiloidus Kethley, 1972, in both sexes, by the presence of setae vs ' on legs II, the absence of setae dT on legs III and IV; in females, by the presence of median hypostomal protuberances and by short setae l1, l2 and l3. The relationships between the Syringophilidae and their hosts are briefly discussed. A list of all known syringophilid genera and their distribution on bird families is provided.     

Mixacarus (Phyllolohmannia) pectinatus sp. n. (Acari,Oribatida, Lohmanniidae), a new species of oribatid mites from India

A new species of oribatid mites (adult and juvenile instars), Mixacarus (Phyllolohmannia) pectinatus sp. n., is described from India. The new species differs from the majority of species of the subgenus in the absence of distally dilated setae and narrower leaf-shaped setae on dorsal and ventral body sides.     

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.     

Reductive evolutionary trends in two new cavernicolous species of a new Australian cixiid genus (Homoptera: Fulgroidea)

Abstract A new genus, Undarana gen.n., is established to accomodate six new closely related cixiid species from Queensland, Australia: U.tamborina sp. n.(type species), U.gloriosa sp.n., U.towomba sp.n., U. daybora sp. n., U. rosella sp.n. and U.collina sp.n. Two of the species live in lava tubes in northern Queensland and show different degrees of troglomorphy (reduction of eyes and bodily pigmentation) U.rosella is regarded as being troglophilic (facultative cavernicole), adn U.collina as being troglobitic (facultative cavernicole), and U.collina as being troglobitic (obligatory cavernicole), and it is considered likely that they represent a single invasion into the cave environment. Reductive evolutionary trends displayed by cave-dwelling Undarana species are described, and notes on their ecology and distribution are given. Hypotheses on the factors that might have led to cave-adaption in Undarana species are discussed.     

First record of the genus Gratia Thomas (Ephemeroptera,Baetidae) from China with the description of a new species

A new species of Baetidae, Gratia baibungensis sp. n., is described and illustrated based on nymphal stage collected from the southeastern Tibet (Xizang) and the genus is reported for the first time from China. This new species can be readily differentiated from its congeners by the absence of a protuberance on the posterior margin of the abdominal tergum X, glabrate simple submarginal setae on the labrum, and the posterior margin of sterna VI–IX having much longer spatulate setae.     

Four new genera of the PIesiobracon Cameron group (Insecta, Hymenoptera, Braconinae)

Crinibracon gen.n. (type species: Crinibracon malayensis sp.n. from Malaysia), C. indicus sp.n. from India, C. striatus sp.n. from New Guinea, Lyricibracon gen.n. (type species: Lyricibracon bicolorus sp.n. from Brunei), Rugosibracon gen.n. (type species: Rugosibracon maculithorax sp.n. from S. Africa), R. nigerianus sp.n. from Nigeria and Simplicibracon gen.n. (type species: Simplicibracon maculigaster sp.n. from Taiwan) are described and illustrated. A key to the Plesibracon group of genera is provided, together with specific keys for the new genera Crinibracon and Rugosibracon .     

Two new species of oribatid mites of Lasiobelba (Acari,Oribatida, Oppiidae) from Nepal,including a key to all species of the genus

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.     

A new genus and four new species of quill mites (Acari: Prostigmata: Syringophiudae) from phasianid birds (Galuformes: Phasianidae)

A new genus and four new species of the quill mites are described. Galliphilopsis gen. n. (G. francolinus sp. n., type species) differs from the closely related Dissonus Skoracki, 1999 by loss of leg setae dGII, the slightly divergent tips of epimeres I and the stylophore constricted posteriorly. Three new species of the genus Galliphilopsis gen. n. and one new species of the genus Mironovia Chirov and Kravtsova, 1995 are described from galliform birds (Phasianidae) collected at the Museum of Natural History, Wroclaw University (Poland): G. lophurus sp. n. from Lophura leucomelanos, G. bochkovi sp. n. from Tragopan sp. and Alectoris barbara, G. francolinus sp. n. from Francolinus levalliantoides, and Mironovia rouloul sp. n. from Rollulus rouloul.     

New Species of Oribatid Mites of the Superfamily Oripodoidea Jacot, 1925 (Acari,Oribatida) from Trinidad and Tobago

Two new species of oribatid mites of the superfamily Oripodoidea (Acari, Oribatida) are described from Trinidad and Tobago. Scheloribates (Scheloribates) tobagoensis sp. n. (Scheloribatidae) differs fromS. (Scheloribates) papillaris Tseng, 1984 in the structure of the rostral and lamellar setae and leg solenidia, in the length of the prolamellae, the absence of aggenital setae, and in reduction of setae on tarsi III. Areozetes ryabinini sp. n. (Haplozetidae) differs from A. altimontanus Hammer, 1961 in the structure of the bothridial and notogastral setae and rostrum and in the number of claws on the tarsi.     

Viracochiella orientalis, a new species of oribatid mites (Acariformes, Oribatida) of the family Ceratozetidae from Sakhalin

A new species, Viracochiella orientalis sp. n., from the southern part of Sakhalin is described. The species differs in the shape of cuspises with strong medial teeth and in the absence of translamellae. The smooth notogaster, shorter interlamellar and genital setae, and some other characters distinguish this species from V. tuberculata. This species differs from V. sergienkoae in the number of genital setae (V. sergienkoae has five pairs), shorter interlamellar setae, smooth trichobothria, fine pore areas without borders of sclerotization, and thin hysterosomal setae.     

Three new species of the subgenus Neoribates (Neoribates) (Acari,Oribatida, Parakalummidae) from Nepal

Three new parakalummid mites of the subgenus Neoribates (Neoribates), N. (N.) parabulanovae sp. n., N. (N.) paramacrosacculatus sp. n. and N. (N.) pararotundus sp. n., are described from Nepalese soils. Neoribates (Neoribates) parabulanovae sp. n. is morphologically most similar to N. (N.) bulanovae Grishina, 2009, N. (N.) rotundus Aoki, 1982 and N. (N.) setiger Balogh & Mahunka, 1978, however, it differs from N. (N.) bulanovae by the body length, body and leg integument, morphology of bothridial setae, absence of aggenital setae, length of interlamellar setae and location of adanal setae ad₃; from N. (N.) rotundus by the body size, body integument, morphology of bothridial setae and length of interlamellar setae; from N. (N.) setiger by the body size, number of genital setae and absence of aggenital setae. Neoribates (Neoribates) paramacrosacculatus sp. n. is morphologically most similar to N. (N.) macrosacculatus Aoki, 1966, however, it differs from the latter by the body size, body integument, length and morphology of bothridial setae, number of genital setae, absence of lamellar setae and length of interlamellar setae. Neoribates (Neoribates) pararotundus sp. n. is morphologically most similar to N. (N.) rotundus, however, it differs from the latter by the number of notogastral setal alveoli, body integument and length of interlamellar setae.     

Six new species of marine Tubificidae (Oligochaeta) from the continental shelf off Peru

Six species of marine tubifieids are described from the continental shelf off Peru. Two of them are members of the gutless genus Olavius Erséus, 1984 (subfamily Phallodrilinae). Olavius bullatus sp.n. possesses 2 pairs of large penial setae in voluminous copulatory sacs, tiny atria, and spermathecal pores in line with dorsal setae. Olavius crassitunicatus sp.n. is characterized by small atria with thin muscular layer, spermathecae with short ducts, opening dorso-laterally, and lack of penial setae. Four species arc members of the subfamily Limnodriloidinae. Limnodriloides busilicus sp.n. belongs to the appendiculatus-group (sensu Erséus). It is discriminated by somatic setae with subdental ligaments, and its voluminous elongate prostatic pads. Limnodriloides clavellatus sp.n. is distinguished from its congeners by a peculiar bulge in the cavity of each atrial ampulla, and spermatozeugmata imbedded in the walls of the spermathecae. Tectidrilus intermixtus sp.n. is similar to T. bori (Righi & Kanner, 1979); it is distinguished from the latter by having trisetal bundles in segment V or V-VI and by lacking copulatory glands. Marcusaedrilus peruanus sp.n. is characterized by nongranulated atrial ducts and bipartite spermathecae.     

A new family, genus, and seven new species of Entodiniomorphida (Protozoa) from the gut of African rhinoceros

This report deals with a group of ciliated protozoa with short ciliary bands found mainly in the cecum of black rhinoceros, Diceros bicornis (linnaeus, 1758), and white rhinoceros, Ceratotherium simum (Burchell, 1817) from southern Africa. A new genus, Rhinozeta, based on the sum total of the characteristics of seven new related species is described. The species described are R. rhinozeta n. sp., R. triciliata n. sp., R. caecalis n. sp., R. addoensis n. sp., R. cristata n. sp., R. multiplatus n. sp., and R. unilaminatus n. sp. The specific features of the new genus make it incompatible with any of the known families of the Order Entodiniomorphida containing the ciliates present in the digestive tract of herbivorous mammals. This merits the creation of a new family, the Rhinozetidae.     

A new oribatid mite species of the genus Protoribates (Acari,Oribatida, Haplozetidae) from Ethiopia

A new oribatid mite species, Protoribates aethiopicus sp. n., from Ethiopia is described. This species is morphologically similar to Protoribates dentatus (Berlese, 1883), but differs from it in the longer lamellae and notogastral setae, shorter adanal setae ad ₁ and smaller notogastral porous areas, as well as in the presence of two claws on all legs.
