A review of the genus Isaurus Gray, 1828 (Zoanthidea), including new records from Fiji

Summary

The first case is reported of a non-lethal interaction between a butterfly and tachinid which had little effect on host or parasite, and is discussed in its implications in relation to tropical tachinids and their hosts.     

A survey of the genus Stegana Meigen from southern Japan (Diptera,Drosophilidae), with descriptions of three new species

Nine species of genus Stegana from southern Japan, including three new species, S. (Oxyphortica) nigripennis Hendel, S. (Steganina) ctenaria Nishiharu, S. (Steganina) izu Sidorenko, S. (Steganina) kanmiyai Okada and Sidorenko, S. (Steganina) masanoritodai Okada and Sidorenko, S. (Steganina) ornatipes Wheeler and Takada, S. (Oxyphortica) dendrobium sp. nov., S. (Steganina) biprotrusa sp. nov. and S. (Steganina) bacilla sp. nov. are surveyed and described with designation of a new synonym S. (Steganina) maymyo Sidorenko. A key to all species of genus Stegana from southern Japan is provided.     

Reproduction and morphology of Polydorella (Polychaeta: Spionidae), including the description of a new species from the Philippines

A new spionid polychaete, Polydorella kamakamai, associated with sponges is described from the Philippines. Polydorella kamakamai is characterized by acicular neurosetae in segments 2–7, a fifth segment containing a ventral row of spines with digitiform bosses, and lack of branchiae. As in all members of the genus, P. kamakamai undergoes asexual reproduction via paratomy; the process of paratomy is examined through scanning electron and light microscopy. This species exhibits a growth zone following segment 10, leading to the production of stolon individuals budding from the stock individual; five or more individuals can thus be formed in a single chain. Paratomic division typically occurs in chains containing four to five individuals and as a result colonies are dominated by chains of two individuals. Sexual reproduction is documented for only the second time in the genus; P. kamakamai produces eggs in segments 13–15. Asexual reproduction and fine morphological structure of the ventral spines of the fifth segment are examined by SEM in P. dawydoffi and P. stolonifera. Polydorella dawydoffi is recorded for the first time from the Philippines and the Red Sea and these are compared to type specimens from Vietnam. The ventral spines of P. dawydoffi contain eight or nine rounded or pointed teeth along the apical end and a capillary extension not previously observed with light microscopy. Notes on feeding biology, parasitism by copepods, and a discussion of the evolutionary relationships of Polydorella and other polydorids are provided.     

A new species of the genus Nanosesarma (Crustacea: Decapoda: Brachyura: Sesarmidae), and redescription of Nanosesarma jousseaumei (Nobili, 1906), including new records from the Persian Gulf

A new species of sesarmid crab from the Persian Gulf, Nanosesarma sarii n. sp. is described. Further, a poorly known species, N. jousseaumei (Nobili, 1906 Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar]), is recorded from the Persian Gulf and recognized as a valid species. N. sarii n. sp. is allied to N. minutum (De Man, 1887) and N. jousseaumei (Nobili, 1906) Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar], but is easily distinguishable from them through a number of characters, in particular the upper surface of the palm with a longitudinal granular ridge, the upper surface of the movable finger fully covered with tubercles, and abdomen of the male with the sixth segment wide and the seventh segment remarkably elongate. N. jousseaumei differs from its remaining congeners in having a large gap between the cheliped fingers, a large tubercle proximally on the outer surface of the movable finger, and large teeth on the posterior margin of the merus of the walking legs.     

Alien polychaete species (Annelida: Polychaeta) on the southern coast of Turkey (Levantine Sea,eastern Mediterranean), with 13 new records for the Mediterranean Sea

The examination of benthic material collected from different depths and habitats along the southern coast of Turkey (Levantine Sea, eastern Mediterranean) in September and October 2005 revealed 30 alien polychaete species belonging to 15 families. Thirteen species (Pisione guanche, Linopherus canariensis, Onuphis eremita oculata, Lumbrineris perkinsi, Dorvillea similis, Timarete caribous, Pherusa parmata, Pherusa saldanha, Streblosoma comatus, Polycirrus twisti, Laonome triangularis, Branchiomma bairdi and Janua steueri) are new to the Mediterranean fauna, 24 species are new to the Turkish fauna and 27 species are new to the Levantine coast of Turkey. The specimens collected from the Levantine coast of Turkey and northern Cyprus that were previously identified as Linopherus acarunculata and Branchiomma boholense are reidentified as L. canariensis and B. bairdi, respectively. In the light of present knowledge, the previous reports of Lumbrineris inflata and Streblosoma hesslei from the Mediterranean (Italian coast) could refer to the species L. perkinsi and S. comatus, respectively. The species new to the Mediterranean Sea are redescribed and discussed.     

Minibiotus acadianus (Eutardigrada: Macrobiotidae), a new species of Tardigrada from southern Louisiana, U.S.A.

Over 200 species of freshwater and terrestrial water bears (phylum Tardigrada) are known to occur in North America. Of these, 16 species have been collected in Louisiana. Foliose and fruticose lichens collected on 18 April 2010 in Acadia Parish, Louisiana, were stored in paper envelopes and later soaked in tap water overnight. Tardigrade specimens and eggs were extracted and mounted in polyvinyl lactophenol. The samples contained a new species of tardigrade. Minibiotus acadianus sp. n. has a buccal tube with single anterior curvature, 2 macroplacoids and 1 microplacoid. Small gibbosities are present on the fourth pair of legs, in 3 caudal rows, and in a single row at the level of the third pair of legs. Minibiotus acadianus sp. n. differs from the most similar tardigrade species, Minibiotus fallax (found in Australia and Florida), in having a shorter and wider buccal tube, a different pattern of gibbosities, and short, peg-shaped processes in addition to long, filamentous processes on the eggs. Reexamination of specimens identified as M. fallax in an earlier paper on the Tardigrada of Louisiana indicates that they are, in fact, M. acadianus sp. n., suggesting that the new species is widely distributed in Louisiana. Se conocen más de 200 especies de osos de agua (phylum Tardigrada) terrestres y de agua dulce que ocurren en Norteamérica. De éstas, 16 se han colectado en Louisiana. Se colectaron líquenes foliosos y fruticosos en la parroquia de Acadia, Louisiana, el 18 de abril de 2010, los cuales fueron guardados en sobres de papel y después remojados en agua de la llave durante toda la noche. Se extrajeron especímenes y huevos de tardígrados y se fijaron en polivinilo lactofenol. Las muestras contenían una nueva especie de tardígrado. Minibiotus acadianus sp. n. tiene un tubo bucal con una única curvatura anterior, dos macroplacoides y un microplacoide. Pequeñas gibosidades están presentes en el cuarto par de patas, en tres hileras caudales y en una sola hilera al nivel del tercer par de patas. Minibiotus acadianus sp. n. difiere de la especie más próxima, Minibiotus fallax, una especie que se encontró en Australia y Florida, porque tiene un tubo bucal más corto y ancho, un patrón distinto de gibosidades y apófisis cortas en forma de estaquilla en los huevos, además de apófisis largas y filamentosas. Una reexaminación de los especímenes identificados como M. fallax en una publicación previa sobre los tardígrados de Louisiana indica que son más bien M. acadianus sp. n., lo cual sugiere que esta nueva especie tiene una distribución extensa en Louisiana.     

A new Odonata family from the Jurassic of Central Asia (Odonata: Epiproctophora)

The new damsel‐dragonfly family Paragonophlebiidae is described based on a new genus and two new species from the Middle‐Late Jurassic of Central Asia.     

Mites of the family Oppiidae (Acari: Oribatida) from Turkey

Two new oppiid species (Gressittoppia luxtoni, Anomaloppia ozkani) and one new subspecies (Graptoppia sundensis acuta) are described from Turkish soils, and two known species are recorded for the first time. The genera Gressittoppia, Anomaloppia and Graptoppia are redefined and keys provided to the known species.     

A new species of Pandaridae (Copepoda), from the whale shark Rhincodon typus (Smith)

The copepod Pandarus rhincodonicus sp. nov. (Copepoda: Pandaridae), collected from whale sharks, Rhincodon typus (Smith, 1828) (Orectolobiformes: Rhincodontidae), swimming off the North West Cape of Western Australia, is described. Pandarus rhincodonicus is closely related to Pandarus cranchii Leach, 1819. However, P. rhincodonicus differs from P. cranchii in: the armature of the posterior margin of the cephalon; the plates of segment 2 extend almost to the limit of segment 4; the shape of the caudal rami and shape of the dorsal abdominal plate; and the distribution and numbers of spines and setae on thoracic appendages. It is suggested that P. rhincodonicus is a commensal.     

A review of the South-East Asian Nasutitermitinae (Isoptera: Termidae), with descriptions of one new genus and a new species and including a key to the genera

This paper describes Snootitermes leuserensis, gen. et sp. nov. (collected from the Leuser Ecosystem, Sumatra), Hirtitermes brabazoni sp. nov. (collected from north Sulawesi) and the major soldier of Ceylonitermes indicola. It also includes a revised generic key to the Nasutitermitinae of Peninsular Malaysia, Java, Sumatra and Borneo and reassigns the South-East Asian Subulitermes-group of termites to the Nasutitermes-group. Aciculioiditermes denticulatus and A. sarawakensis are considered to be junior synonyms of Aciculioiditermes holmgreni. The genera Aciculioiditermes and Proaciculitermes are considered to be junior synonyms of Malaysiotermes. Therefore Aciculioiditermes holmgreni, Proaciculitermes orientalis, P. sabahensis, P. malayanus and P. lowi are all Malaysiotermes species. Tho's (1982, 1992) unpublished new genus (Genus A) is considered to be a new species of Ceylonitermes. Oriensubulitermes borneensis is shown to be a Subulioiditermes species, S. borneensis. Nasutitermes matangensiformis is shown to be a junior synonym of N. matangensis. Havilanditermes is shown to be a junior synonym of Nasutitermes.     

Some new species of the family Zerconidae (Acari: Mesostigmata) from Turkey

Three new species of zerconid mites, Prozercon (Prozercon) mersinensis, P. (Prozercon) yavuzi and P. (Prozercon) kafkasoricus, from Turkey are described and illustrated, and a key to adults of known species of Prozercon provided.
