AbstractRhabdias garhwalensissp. nov. from the lungs ofDuttaphrynus himalayanus(Günther, 1864) collected in Kimoi Tehsil, district Tehri Garhwal (Uttarakhand), India is described and illustrated.Rhabdias garhwalensissp. nov. represents the 15th species described from the Oriental zoogeographical zone and the 9th species from India. The new species is differentiated from the closely related Oriental species in having 6 lips, cup–shaped buccal cavity with muscular striations in the posterior region and smaller esophagus to body length ratio. In addition to the new species, a second species,Cosmocercoides bufonisKarve, 1944, was found in the large intestine ofD. himalayanus.

Abstract Rhabdias stomatica sp. nov. from the lungs of Duttaphrynus stomaticus (Lutken, 1864) from Dehradun, Uttarakhand, India is described and illustrated. Rhabdias stomatica sp. nov. is the 16th species described from the Oriental biogeographical region and the 8th species from India. The new species is differentiated from the closely related Oriental species in having 4 weakly developed lips, a trapezoidal shaped buccal cavity, different position of nerve ring and in the esophagus/body length ratio. In addition, to the new species found in the lungs, mature specimens of Aplectana macintoshii (Stewart, 1914) Travassos, 1931 and larvae representing two unidentified species of nematode were found in the large intestine of the D. stomaticus.

AbstractChoanocotyle platti sp. nov. (Digenea, Choanocotylidae) is described from the northern long-necked turtle, Chelodina rugosa (Pleurodira, Chelidae) from the Daly and Mary Rivers, Northern Territory, Australia. This is the fifth known member of Choanocotyle. Choanocotyle platti sp. nov. differs from Choanocotyle nematoides Jue Sue et Platt, 1998 and Choanocotyle hobbsi Platt et Tkach, 2003 by smaller body length, larger oral sucker, relatively greater distance between tests, and prepharynx with an infolded posterior region. In addition the new species does not have the looped cirrus sac characteristic of Choanocotyle nematoides. Comparison of sequences of 18S, ITS (ITS1, 5.8S, ITS2) and partial 28S regions of nuclear rDNA among all 3 species strongly supports the status of Choanocotyle platti sp. nov. as a new species.

The genus Psyllaphorura is reported from China for the first time. A new species, Psyllaphorura jiangsuensis sp. n. as the eighth species of the genus, is described from Nanjing, Southeast China. It is most similar to the Russian species Psyllaphorura martynovae (Stebaeva, 1985) in many respects. However, it can be distinguished from the latter by number of vesicles in the postantennal organ, number of setae on ventral tube, length ratio of unguiculus to unguis, absence of unguiculus basal lamella and maximum body length. A key to all of the species of Psyllaphorura is provided.

Abstract Coomansus batxatensis sp. nov., recorded from Vietnam, is described and illustrated and its phylogenetic relationship within the Mononchida is analysed. The molecular data (18S and 28S ribosomal DNA) are provided for the new species. The new species is characterized by small body size (body length, L = 0.7–0.9 mm); buccal cavity sub-rectangular in shape, flattened at base, 21–24 × 12–13 μm or 1.9 (1.7–2.0) times as long as wide; posterior position of dorsal tooth apex (59–63% from the base of buccal cavity); pars refringens vaginae with faint and small (2.5 × 1.7 μm) teardrop-shaped pieces, short pars distalis vaginae; and males with short spicules (50–51.5 μm) with rounded head and conical blade part. The new species is close to Coomansus parvus but differs from it by the smaller buccal cavity size, more posterior position of the dorsal tooth apex, longer tail and presence of males. An updated identification key to Coomansus species and a compendium of all the species known are presented.

Four additional species of quill mites of the family Syringophilidae Lavoipierre have now been recorded in England. This includes one new species, Bubophilus aluconis sp. nov., which parasitizes the tawny owl Strix aluco (Strigiformes: Strigidae). It differs from other species of this genus, B. ascalaphus Philips et Norton, 1978 and B. asiobius Skoracki et Bochkov, 2002 by the number of chambers in transverse branch of the peritremes (2-3), the length ratio of setae vi and ve (1:1.6-2), and the lengths of the stylophore and aggenital setae ag1 (180 and 135-145, respectively).

Summary A new species of free-living marine nematode, Diplolaimella ariakensis n. sp., is described from a muddy tidal flat of the Ariake Sea, southern Japan. Diplolaimella ariakensis n. sp. differs from its congeners by the following: presence of ocelli, absence of denticles in the buccal cavity, a long tail (11-14 cloacal body diam., c = 3.2-4.0 in male, 17-21 anal body diam., c = 2.9-3.4 in female), spicules as long as 1.4-1.8 cloacal body diam., gubernaculum 0.4-0.5 cloacal body diam. long with a dorsocaudal apophysis 0.5-0.7 cloacal body diam. long, presence of a precloacal supplement, absence of postcloacal papillae, presence of seven pairs of body pores in male, and the anterior position of the vulva (V = 43-46). A dichotomous key to Diplolaimella species is provided. Almost full-length 18S rRNA and partial cytochrome c oxidase subunit I gene sequences were determined for D. ariakensis n. sp. A maximum likelihood tree of 18S sequences supported a close relationship between D. ariakensis n. sp. and D. dievengatensis.

AbstractA new species of Bipaliid land planarian, Bipalium bengalensis is described from Suri, West Bengal, India. The species is jet black in colour without any band or line but with a thin indistinct mid-dorsal groove. Semilunar head margin is pinkish in live condition with numerous eyes on its margin. Body length (BL) ranged from 19.00 to 45.00mm and width varied from 9.59 to 13.16% BL. Position of mouth and gonopore from anterior end ranged from 51.47 to 60.00% BL and 67.40 to 75.00 % BL respectively. Comparisons were made with its Indian as well as Bengal congeners.Salient features, distribution and biometric data of all the 29 species of Indian Bipaliid land planarians are revised thoroughly. Genus controversy in Bipaliid taxonomy is critically discussed and a proposal of only two genera Bipalium and Humbertium is suggested.

A new species of Justicia (Acanthaceae), J.thailandica, is described and illustrated from Thailand. The new species belongs to Justiciasect.Harnieria and is similar to J.quadrifaria and J.championii, but differs on account of the obviously densely white indumentum in the inflorescence bracts and calyx, ovate leaf blades with margin usually entire, spathulate inflorescence bracts and length ratio of calyx to mature capsule. It is assessed to be “Near threatened” (NE) according to IUCN Red List Category and Criteria. Pollen and seed morphology characters are also reported. Species of Justiciasect.Harnieria in Thailand are discussed and a key to the three recognized species is presented.

From a survey of helminths of the alimentary tracts of 26 hydromyins; 11 Leptomys, 1 Mayermys, 3 Neohydromys, 9 Paraleptomys, and 2 Parahydromys from Papua New Guinea an acanthocephalan, Porrorchis hydromuris; a cestode, Mathevotaenia sp.; the trematodes, Brachylaima sp., and a psilostome; and the nematodes, Heterakis fieldingi, Odilia mackerrasae, O, emanuelae, Protospirura kaindiensis, Rictularia mackerrasae, and Capillaria sp. s.l., as well as encapsulated larval ascaridids were found. All represent new host records. Labiobulura leptomyidis n. sp. (Subuluridae), differs from its congener in having longer spicules, no spines on the chordal lobes of the buccal cavity and it is described from Leptomys spp. Spirurida or Ascaridida were the dominant taxa in each helminth assemblage, with dietary preferences being a determinant. Either coevolution and or host switching, sometimes associated with migration between Australia and Papua New Guinea, also appear to have influenced the development of the helminth assemblage in each host taxon.

A new species of Eurycopinae (Munnopsidae) Eurycope crassiramis sp. nov. is described from the bathyal of the Weddell Sea, Southern Ocean. The new species is most similar to E. gaussi Wolff, 1956. Both species can be distinguished from all other species of this genus by the short cephalon and ambulosome (each length in the new species is 0.1 body length), a rostrum equal or subequal to medial cephalic length, a uropod with very broad rami and a protopod not broadened medially, and the peculiar form of the male pleopod 1. The new species differs from E. gaussi by the following characters: a lacinia mobilis with 6 denticles, a mandibular spine row with 6–7 setae, and a distolateral margin of male pleopod 1 broadly rounded, without projecting corners.
