A contribution to the knowledge of the anostracan fauna of Iran

We report the finding of three anostracan species, Chirocephalus skorikowi Daday, 1913, Branchinecta orientalis Sars, 1901 and Branchinella spinosa. Milne-Edwards, 1840 in different localities in northwestern Iran. C. skorikowi was recorded in a lake at an elevation of 2400 m, whereas B. orientalis was found in a pond at 1280 m a.s.l. Co-existing B. spinosa and B. orientalis were collected in a pool close to the town of Tabriz, formerly indicated by Brehm (1954) as Estakr Chah, presently named EalGoli. Unlike Brehm (1954), we did not find Streptocephalus in the area of Tabriz.     

The taxonomy of the family Paramphistomidae Fischoeder, 1901 with special reference to the morphology of species occurring in ruminants. III. Revision of the genus Calicophoron Näsmark, 1937

Summary The genus Calicophoron N?smark, 1937 is redefined. Only the following species originally assigned by N?smark to the genus are considered valid: C. calicophorum (Fischoeder, 1901) N?smark, 1937 (type species); C. papillosum (Stiles & Goldberger, 1910) N?smark, 1937; and C. raja N?smark, 1937. The following species previously assigned to the genus Paramphistomum Fischoeder, 1901 are considered valid but moved to the genus Calicophoron N?smark, 1937 in new combinations: C. bothriophoron (Braun, 1892); C. microbothrium (Fischoeder, 1901); C. papilligerum (Stiles & Goldberger, 1910); C. clavula (N?smark, 1937); C. microbothrioides (Price & McIntosh, 1944); C. sukari (Dinnik, 1954); C. phillerouxi (Dinnik, 1961); C. daubneyi (Dinnik, 1962) and C. sukumum (Dinnik, 1964). The genus Bothriophoron (Stiles & Goldberger, 1910) Grétillat 1958 is synoymized with Calicophoron N?smark, 1937. Paramphistomum crassum Stiles & Goldberger, 1910, P. cauliorchis Stiles & Goldberger, 1910, P. ijimai Fukui, 1922, P. (Cauliorchis) skrjabini Popova, 1937, P. erschovi Davydova, 1959, Calicophoron orientalis Mukherjee, 1966, C. wuchengense Wang, 1979 and Cotylophoron skrjabini Mitskevich, 1958 in part are considered synonyms of Calicophoron calicophorum (Fischoeder, 1901) N?smark, 1937. C. zhejiangense Wang, 1979 is regarded a synonym of C. papillosum (Stiles & Goldberger, 1910) N?smark, 1937. P. vangrembergeni Van Strydonck, 1970 and P. togolense Albaret, Bayssade-Dufour, Guilhon, Kulo & Picot, 1978 are considered synonyms of Calicophoron phillerouxi (Dinnik, 1961) n. comb. and Ceylonocotyle petrovi Davydova, 1961 is synonymized with Calicophoron microbothrioides (Price & McIntosh, 1944) n. comb. The species considered valid under the genus are redescribed and illustrated and scanning electron photomicrographs of the tegumental surfaces of some species are provided. A key to the species is given. Part of a thesis approved by the University of London for the award of the Ph.D. degree.     

First record of the family Thamnocephalidae (Crustacea: Anostraca) from Southeast Asia and description of a new species of Branchinella

During a two-year investigation of freshwater microcrustaceans in Thailand, an undescribed species of fairy shrimp of the genus Branchinella Sayce, 1903 in the family Thamnocephalidae, was discovered. This is the first record of the genus and the family from Southeast Asia and the second anostracan reported from Thailand. The new species, Branchinella thailandensis n. sp. appears to be morphologically intermediate between B. kugenumaensis (Ishikawa, 1895) from Japan and east China, and B. madurai Raj, 1951 from India and Pakistan. B. thailandensis n. sp. was collected from several temporary ponds in 11 provinces of the northeast and the central Thailand, often co-occurring with Streptocephalus sirindhornae Sanoamuang, Murugan, Weekers & Dumont, 2000.     

The taxonomy of the family Paramphistomidae Fischoeder, 1901 with special reference to the morphology of species occurring in ruminants. V. Revision of the genus Cotylophoron Stiles & Goldberger, 1910

These are redescribed and illustrated. Scanning electron photomicrographs of the tegumental surfaces of some species are provided. C. guangdongense Wang, 1979 is considered a synonym of C. cotylophorum (Fischoeder, 1901) Stiles & Goldberger 1910, and C. indicum of N?smark, 1937 (not of Stiles & Goldberger, 1910) and C. noveboracensis Price & McIntosh, 1953 are considered synonyms of C. fuelleborni N?smark, 1937. C. ottoi Gupta & Bakhshi in Gupta & Nakhasi, 1977 is regarded as a species inquirenda. A key to the species of the genus is given. Part of a thesis approved by the University of London for the award of the Ph.D degree.     

Review of Colombian Conchostraca (Crustacea) — morphotaxonomic aspects

This paper presents an overview of the current knowledge about species diversity and morphological taxonomy of the Colombian conchostracan fauna. Relationships among morphological variability, reproduction biology and environmental conditions are stressed. The Colombian fauna includes 12 species in five families: Limnadiidae Sars, 1896; Leptestheriidae Daday, 1915; Cyclestheriidae G. O. Sars, 1899; Metalimnadiidae Strakraba, 1965; and Lynceidae Stebbing, 1902. No member of the families, Cyzicidae Stebbing, 1910, or Imnadiidae Botnariuc & Orghidan 1941 have been found in Columbia. Morphology depends on developmental stage and on the modulating effects of environmental conditions. Extremely high temperatures may lead to specimens with neotenic features inEulimnadia magdalenensis Roessler, 1990.

The taxonomy of the family Paramphistomidae Fischoeder, 1901 with special reference to the morphology of species occurring in ruminants. II. Revision of the genus Paramphistomum Fischoeder, 1901

Summary The genus Paramphistomum Fischoeder, 1901 is redefined and restricted and only the following species are retained and considered valid: P. cervi (Zeder, 1790) (type species); P. liorchis Fischoeder, 1901; P. gracile Fischoeder, 1901 P. epiclitum Fischoeder, 1904; P. gotoi Fukui, 1922, P. ichikawai Fukui, 1922; P. leydeni Näsmark, 1937 and P. hiberniae Willmott, 1950. These are redescribed and illustrated. A new species, Paramphistomum cephalophi is described and illustrated from the black-fronted duiker (Cephalophus nigrifrons) in Rwanda. It differs from the rest of the species in the genus by the presence of an anterior sphincter in the pharynx and the characteristic posterior notch of the acetabular rim. Scanning electron photomicrographs of the tegumental surfaces of the species in the genus are provided. Cotylophoron indicum Stiles & Goldberger, 1910 (=Paramphistomum thapari Price & McIntosh, 1953), C. madrasense Gupta, 1958, C. chauhani Gupta & Gupta, 1972, Paramphistomum indicum Stiles & Goldberger, 1910 (in part), P. malayi Lee & Lowe, 1971 and Srivastavaia indica Singh, 1970 are considered synonyms of Paramphistomum epiclitum Fischoeder, 1904. Paramphistomum indicum Stiles & Goldberger, 1910 (in part) and P. bombayiensis Gupta & Verma in Gupta & Nakhasi, 1977 are regarded as synonyms of Paramphistomum gracile Fischoeder, 1901. P. scotiae Willmott, 1950, P. julimarinorum Velázquez-Maldonado, 1976, P. nicabrasilorum Velázquez- Maldonado, 1976, P. procapri Wang, 1979 and Cotylophoron skrjabini Mitskevich, 1958 are considered synonyms of Paramphistomum leydeni Näsmark, 1937. Cotylophoron vigisi Davydova, 1963 is considered synonymous with Paramphistomum ichikawai Fukui, 1922. Paramphistomum birmense Railliet, 1924, P. microon Railliet, 1924, P. chinensis Hsu, 1935 and P. pseudocuonum Wang, 1979 are regarded as species inquirendae.The genera Liorchis Velichko, 1966 and Srivastavaia Singh, 1970 are synonymized with Paramphistomum Fischoeder, 1901.A key to the species of the genus is provided.Part of a thesis approved by the University of London for the award of the Ph.D. degree.Part of a thesis approved by the University of London for the award of the Ph.D. degree.     

Contributions to the knowledge of the Cladocera of north-east Thailand

Examination of 200 samples from 93 freshwater habitats in north-eastThailand revealed 60 taxa of Cladocera, of which 31 are new to the Thaifauna. Six species (Disparalona caudata Smirnov; Leydigialaevis Gurney; Leydigiopsis sp.; Macrothrix flabelligeraSmirnov; Macrothrix cf. paulensis Sars; and Pseudosidaramosa Daday) are new to Asia. The majority of the Cladocera recorded arecircumtropical species. Comments and figures are presented on several ofthe new records for Asia and Thailand. This revised version was published online in July 2006 with corrections to the Cover Date.     

Descriptions of new edaphic and aquatic species of Chlorococcum Meneghini (Chlorococcales)

The re-examination of plankton samples taken from Lough Neagh in 1900 by West & West (1902, 1906) and in 1910 by Dakin & Latarche (1913) indicates that Stephanodiscus astraea had been wrongly identified as Coscinodiscus lacustris. The absence of C. lacustris from the lake sediments is consequently explained.
