Five additions to the list of Sepsidae Diptera for Vietnam: Perochaeta cuirassa sp. n., Perochaeta lobo sp. n., Sepsis spura sp. n., Sepsis sepsi Ozerov, 2003 and Sepsis monostigma Thompson, 1869

A recent collecting trip to Vietnam yielded three new species and two new records of Sepsidae (Diptera) for the country. Here we describe two new species in the species-poor genus Perochaeta (Perochaeta cuirassasp. n. andPerochaeta lobosp. n.) and one to the largest sepsid genus Sepsis (Sepsis spurasp. n.) which is also found in Sumatra and Sulawesi. Two additional Sepsis species are new records for Vietnam (Sepsis sepsi Ozerov, 2003; Sepsis monostigma Thompson, 1869). We conclude with a discussion of the distribution of Perochaeta and the three Sepsis species.     

Praealbonemertes whangateaunienses n. gen. and n. sp., a new heteronemertean from New Zealand

Abstract

A new genus and species of heteronemertean, Praealbonemertes whangateaunienses n. gen. and n. sp., is described and illustrated. The species is characterised by inter alia a cephalic lacuna with strands of longitudinal muscle fibres, a proboscis with three muscle layers, and a well-developed muscle plate dorsal to the foregut and anterior intestine. The material was collected in New Zealand.     

Redescription of a poorly known marine ciliate, Leptoamphisiella vermis Gruber, 1888 n. g., n. comb. (ciliophora, stichotrichia, pseudoamphisiellidae), from the Yellow Sea, China

Leptoamphisiella vermisGruber, 1888 n. g., n. comb. (basionym Epiclintes vermisGruber, 1888) is an extraordinarily large and worm-like marine stichotrichous ciliate. Based on a population isolated recently from coastal waters of Qingdao, China, the living morphology and infraciliature are redescribed and its taxonomic position is defined. Accordingly, a new diagnosis for this species is suggested: large, marine Leptoamphisiella with a conspicuous layer of pellicular alveoli; 400-1000 microm x 40-70 microm in vivo; body band-like, highly flexible; about 40 membranelles; always three frontal and two buccal cirri; 52-80 transverse cirri (TC) extending to the posterior end of the buccal field; 57-79 left midventral and 44-62 right midventral cirri; 62-102 cirri in left and 63-91 cirri in right marginal rows (MR); 9-13 dorsal kineties that extend the full body length; about 100 macronuclear nodules and 5-13 micronuclei. The diagnosis for the new genus is as follows: vermiform Pseudoamphisiellidae with strongly contractile body, differentiated frontal, buccal, and highly developed TC; two remarkably separated midventral rows; one MR on each side of the body; frontoterminal and caudal cirri absent. Leptoamphisiella vermis n. comb. is fixed as the type species of the new genus.     

Two New Diophrys‐Like Genera and Their Type Species,Apodiophrys ovalis n. g., n. sp. and Heterodiophrys zhui n. g., n. sp. (Ciliophora: Euplotida), with Notes on Their Molecular Phylogeny

ABSTRACT. Based on both morphological and molecular information, two new euplotid genera Apodiophrys n. g. and Heterodiophrys n. g. are described in the present paper. Apodiophrys n. g. is defined as sculptured Diophryinae with bipartite adoral zone; frontoventral cirri arranged in Diophrys‐pattern; marginal cirri located in two clearly separated groups. Heterodiophrys n. g. is recognizable by the combination of Diophrys‐like frontoventral cirri and the unique structure of several marginal cirri that are arranged in a long row. The type species for both new genera, Apodiophrys ovalis n. sp. and Heterodiophrys zhui n. sp., collected from southern China sea, are described. The small subunit rRNA (SSU rRNA) gene sequences for both new taxa are determined. Phylogenetic analyses based on these data indicate that Apodiophrys is most closely related to Paradiophrys, which then clusters with Uronychia species. Thus, Apodiophrys–Paradiophrys is separated from other typical Diophrys‐like genera in the SSU rRNA gene trees. The new genus Heterodiophrys is basal to the sister group of Diophrys–Diophryopsis, hence belongs to the “core”Diophrys‐complex.     

Macrosiagon deuvei n. sp. (Coleoptera: Ripiphoridae) from the French Eocene amber

Macrosiagon deuvei n. sp., the second fossil representative of this extant genus of Ripiphoridae: Ripiphorinae: Macrosiagonini is described from the lowermost Eocene amber of Oise (France). The new species is compared with the extant species of the genus. Taxonomic position of other two fossil representatives of the family described from France by Perrichot et al. (2004) is discussed. The genus Paleoripiphorus Perrichot et al. 2004 is tentatively transferred from Ripiphorinae to Ripidiinae.     

Pararotylenchus n. gen. (Pararotylenchinae n. subfam., Hoplolaimidae) with Six New Species and Two New Combinations

A new subfamily, Pararotylenchinae, (Hoplolaimidae) is described. It includes a single genus, Pararotylenchus n. gen., six new species, attd two new combinations, Pararotylenchus (syn. Tylenchorhynchus) brevicaudatus (Hopper, 1959) n. comb. and Pararotylenchus (syn. Rotylenchus) pint (Mamiya, 1968) n. comb. Pararotylenchinae is similar to certain other Hoplolaimidae, such as Rotylenchinae, with respect to most characters including the short tail, the position of the phasmids near the anus, and the relatively great distance of the dorsal gland orifice from the base of the stylet knobs. The lip region, as observed with the scanning electron microscope, conforms to the basic pattern for Hoplolaimidae. The labial disc is round with slit-like amphidial openings at the lateral sides of the periphery of the disc. The distinctive anterior-most lip annule is segmented into six sectors. Unlike other Hoplolaimidae, however, the esophageal glands of Pararotylenchinae form a basal bulb similar to that of Tylenchorhynchidae; other characters do not resemble Tylencborhynchidae. Specimens of Pararotylenchus have been recovered only from cool regions at high elevations and Pacific coastal areas in the Western United States, Japan, and Korea.     

Description of Thecavermiculatus andinus n.sp. (Meloidoderidae), a Round Cystoid Nematode from the Andes Mountains of Peru

Thecavermiculatus andinus n.sp. is described and illustrated from Oxalis tuberosa originally collected in the vicinity of Lake Titicaca high in the Andes mountains of southern Peru. This new species differs markedly front the other two species in the genus, especially in having a much greater female vulval-anal distance and annules with lined punctation on most of the female body with a lacelike pattern restricted to the posterior portion, particularly at the vulva and anus which do not protrude. Females are essentially spherical with protruding neck, white to yellowish in color, and can easily be mistaken for potato cyst nematodes. Among the dozen or more known weed and crop host plants are potato and eggplant. In order to accommodate this new species, the genus Thecavermieulatus is emended. A key to the species of this genus is presented.     

Rhododrilus sexpapillatus n.sp. (Oligochaeta: Megascolecidae) from New Zealand

Abstract

A new earthworm species belonging to the acanthodriline genus Rhododrilus is described from the North Island of New Zealand, elevating the generic total (excluding Australian forms) to 30 species. The new taxon forms part of the species-group with incomplete fusion of the male and prostatic terminalia. Its most closely related congener is the geographically proximate R. papaensis. Though exhibiting great heterogeneity, suggestive of polyphyly, the genus remains taxonomically convenient. It probably encompasses convergent forms, the ancestral affinities of which may never be ascertained.     

Dialipsis villahermosae Humala & Selfa n. sp. (Hymenoptera: Ichneumonidae), the second European species of the genus,with biological notes and a key of Palaearctic species

The small genus Dialipsis Förster 1869 (Hymenoptera: Ichneumonidae) includes two known species, of which one is common in Central and Northern Europe. Here we describe the male and female of a new species, Dialipsis villahermosae Humala & Selfa, which was reared from mushrooms collected in Eastern Spain. The host fungus gnat, Mycetophila blanda Winnertz, is a new record for the whole genus, while the rate of parasitism seems very low. Based on environmental data of the collection localities and data available for other two species it is suggested that Dialipsis species occur preferably in cool temperatures habitats. A key of identification of the two known Palaearctic species is provided. D. villahermosae n. sp. differs from D. exilis Förster 1871 in the morphology of the first tergite, referred to the presence of dorsal keels and angle between petiole and postpetiole, and in the convexity of temples.     

Tabanidae (Diptera) of Amaz?nia XXI. Descriptions of Elephantotus gen. n. and E. tracuateuensis sp. n. (Diachlorini) from the Brazilian coast

Elephantotus, a new genus of Tabanidae from the Amazon coast, Brazil, is described based on a new species E. tracuateuensis. Five females were collected in Pará State, and a male in Maranhão State. Arguments are presented for separating the new genus from Dasybasis, as well as the possibility of its occurrence being related to the nesting sites of coastal birds. The new species is characterized by its large size (x = 2.15 cm, n = 5 females), glabrous eyes, reddish-brown tegument, light brown frontal callus not touching the edges of the eyes, extending up to the vertex that has traces of ocelli, basal plate of the antennal flagellum with obtuse angle, without a tooth or spine, wings hyaline, with brown basal cells, without appendix in the fork of vein R₄₊₅, and genital furca wide with extended flaps.     

Succinapion telnovi n. gen. et n. sp. of the tribe Kalcapiini (Coleoptera: Brentidae: Apioninae) in Baltic amber

A new genus and species, Succinapion telnovi n. gen. et n. sp. (Coleoptera: Curculionoidea: Brentidae: Apioninae: Kalcapiini) is described and illustrated from Upper Eocene Baltic amber. The new genus is similar to the genus Melanapion Wagner, 1930 but differs from it in having femora ventrally with spine at distal 1/3, simple claws, a longer rostrum, elytra weakly widened towards apex, longer antennae and slightly narrower elytral striae.http://www.zoobank.org/urn:lsid:zoobank.org:pub:2A95C49D-5589-4ACA-8A87-0DDF635BA25E     

Stenosoma stephenseni sp. n. (Isopoda, Idoteidae), from the southwestern Mediterranean, with a note on the nomenclatural status of Synisoma Collinge, 1917

Recent collections of isopods in Alboran Island and Algeria included several specimens of the species Stenosoma stephensenisp. n. This is the fourteenth species described in the genus Stenosoma Leach, 1814. Examination of two specimens collected during the Danish oceanographic cruises of the Thor (1908-10) close to the Galite Islands, and identified as Stenosoma acuminatum Leach, 1814, revealed that both belong to Stenosoma stephensenisp. n. In light of these findings, the Mediterranean records of Stenosoma acuminatum are revised, and it is proposed that Stenosoma acuminatum is a strictly Atlantic species. An updated diagnosis for the genus Stenosoma is given, together with a key for the identification of its species. The nomenclatural status of the name Synisoma Collinge, 1917 is addressed, and although it is in prevailing usage, it is shown that Stenosoma Leach, 1814 is the valid name of the genus.     

Pelagostrobilidium wilberti n. sp. (Oligotrichea, Choreotrichida): morphology and morphogenesis

Morphology, infraciliature, morphogenetic features, and some ecological data for Pelagostrobilidium wilberti n. sp. are described. This new species was collected from a temporary pond in Magdalena, Buenos Aires province, Argentina, which was sampled monthly from August 2003 to July 2005. The species was found in autumn and winter. Observations were made in vivo and after staining with protargol. Pelagostrobilidium wilberti n. sp. measures 63-84 x 42-49 microm in vivo and is conical in shape, with a posterior spine-like cytoplasmic process. It possesses 6 somatic kineties, with kinety 2 sinistrally curved and shorter than the others. The oral apparatus is composed of 25-32 external and two internal membranelles. The macronucleus is horseshoe-shaped and located beneath the oral apparatus; two or three spherical micronuclei lie dorsally. There is a posterior contractile vacuole. Morphogenesis is hypo-apokinetal and begins dorsally between the curved kinety 2 and kinety 3. After the discovery of this new species, the diagnosis of the genus Pelagostrobilidium was amended.     

A preliminary Study on Dichroa Lour.

Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species, ranging from the mainland of S. E. Asia southward to Pacific islands. But most of the species are more restricted in distribution. Of the 12 recognized species, six are known from South China and Indochina; three are confined to west and northwest New Guinea; two are endemic to the Phillipines. Only one species is widely distributed in S. E. Asia. In the present paper, the genus is divided into two sections and two series based on the number of stamens and the characteristics of the ovary. One species is described as new.     

Stylodrilus californianus n. sp., a new lumbriculid (Annelida: Oligochaeta) from North America

A new species of the genus Stylodrilus is described from phreatic waters in California, North America. Tubular atria with bulbous penes and spermathecae with broad and short ducts characterize the new species. The habitat of Stylodrilus californianus n. sp., confirms that the distribution of the genus Stylodrilus in the Neartic biogeographical zone is mainly associated with subterranean waters.     

Frankliniella lantanae sp. n. (Thysanoptera: Thripidae), a polymorphic alien thrips damaging Lantana leaves in Australia

Abstract  A new species of Frankliniella Karny, probably introduced to Australia from the Caribbean area, is described here as causing feeding damage to the young leaves of Lantana in south-eastern Queensland and northern New South Wales. The new species is unusual within this large, primarily Neotropical genus, in that it feeds only on leaves, not in flowers, and that adult females are either apterous or fully winged. Only 10 of the 160 described species of Frankliniella are known to exhibit wing reduction, and notes are given on these together with notes on the seven species of the genus that are not endemic to the New World. Life history studies, including sex and morph ratios, indicate that egg to adult can require as little as 12 d, but despite breeding well in greenhouses, the species is not known to develop large populations in the field in Australia.     

Munnogonium affinissp. n.: A New Species of Isopod (Asellota: Paramunnidae) from the Coast of Korea,Sea of Japan

The new species Munnogonium affinisfrom the coast of Korea (the Sea of Japan) is described. This is the first record of the genus Munnogoniumfrom the western Pacific. The new species differs considerably from the four eastern Pacific American species of this genus and is most similar to M. maltiniifrom the Mediterranean Sea.     

Tunicothrix rostrata n. g., n. sp., a new urostylid ciliate (Ciliophora, Stichotrichia) from the Yellow Sea

The morphology and infraciliature of a new ciliate, Tunicothrix rostrata n. g., n. sp., isolated from the Yellow Sea, are investigated using live observation and protargol impregnation. Tunicothrix rostrata measures about 160 x 40 mum in vivo, and has a frontal beak-like protrusion, a conspicuous cortical alveolar layer, two right marginal rows, and usually three distinct midventral pairs. The discovery of T. rostrata enables us to reconsider the classification of Erniella wilberti, a curious ciliate with obscure midventral pairs. Both species are highly similar in overall appearance and nuclear and ciliary pattern. Thus, they are united in a new genus of the family Urostylidae, Tunicothrix, and E. wilberti is transferred to Tunicothrix: Tunicothrix wilbertiLin and Song, 2004 n. comb. By contrast, Erniella filiformis, type species of Erniella, has several ventral rows and does not belong to the urostylids. Tunicothrix rostrata is easily distinguished from T. wilberti by its beak-like anterior protrusion and by the distinctly elongated right marginal row 2, which curves anteriorly on the dorsal side of the cells. Tunicothrix is closely related to Parabirojimia, differing by the invariably two (vs. five-eight) right marginal rows and the conspicuous (vs. ordinary) alveolar layer, a unique feature in urostylid ciliates.
