This paper describes three new species ofIsosporafromPycnonotus 1eucogenysin Saudi Arabia (I. gatifenensissp.n.;I. khobarensissp.n. andI. hafoufenensissp.n.). Sporulated oocyats ofI. gatifenensisare ovoidal, 23‐26.5 ± 16.5‐19(25.03 ± 0.12 ± 18.13 ± 0.09))μm and sporocysts are elongated ovoidal 17‐20.5 ± 8‐11 (18.9 ± 0.09 ± 9.3 ± 0.07) μm. Sporulated oocysts ofI. khobarensisare ovoidal 22‐26 ± 15.5‐19 (24.3 ± 0.18 ± 17.1 ± 0.19)μm and sporocysts are pyriform 13‐16 ± 9‐11.5 (14.8 ± 0.15 ± 9.9 ± 0.13)μm. Sporulated oocysts ofI. hafoufenensisare ovoidal 22‐27 ± 19‐24(25.4 ± 0.25 ± 22.1 ± 0.26) μm and sporocysts are ovoidal 1

摘要:

The generic classification of the subfamily Phallodrilinae (with a total of 252 species) is revised according to phylogenetic principles. Morphological character patterns are assessed under the principle of maximum parsimony, but due to the poor resolution and instability in the resulting cladograms, the analysis is supplemented with intuitive weighting of synapomorphic similarities. Thirty‐one genera are recognized. The former definition of the type genusPhallodrilusPicrantoni, 1902, is revised and the members of this genus are reclassified into 20 taxa, each hypothesized to be monophyletic:Phallodrilus s.str. (revised to contain the type species only),Somalidrilusgcn.n.,Milliganiusgen.n.,Phallodriloidesgen.n.,Albanidrilusgen.n.,Abyssidrilusgen.n.,Paraktedrilusgen.n.,UniporodrilusErséus, 1979,Inermidrilusgen.n.,Gianiusgen.n.,Mexidrilusgen.n.,PeosidrilusBaker&Erséus, 1979,AtlantidrilusErséus, 1983,ThalassodrilusBrinkhurst, 1963,Pirodrilusgen.n.,Pirodriloidesgen.n.,Marionidrilusgen.n.,Pectinodrilusgen.n.,Pacifidrilusgen.n. andPseudospiridiongen.n. Nine new species are described from the Northwest Atlantic:Phallodriloides pinnulatussp.n.,Abyssidrilus opulentussp.n.,A. potenssp.n.,A. altoidessp.n.,Mexidrilus obtusussp.n.,Peosidrilus daleisp.n.,P. aduncussp.n.,P. riserisp.n., andAtlantidrilus hamulussp.n. The genusDiscordiprostatusBaker, 1982, is synonymized withNootkadrilusBaker,

摘要:

A new species of the freshwater atyid shrimp,Caridina bruneianafrom Negara Brunei Darussalam, Borneo is described.Caridina bruneianais characterized by its moderately long and deep rostrum, pereiopod shape, spination and segmental ratios, the shape and spination of its posterior telsonic margin, egg size and the presence of an appendix interna on the endopod of the first male pleopod. The distribution of atyid shrimps in forested streams and their possible use as bioindicators of stream water quality in tropical rainforests are briefly discussed.

摘要:

Two new genera,Reductosomagen.n. (Desmosomatidae) andDesmostylisgen.n. (Desmosomatidae), and five new species are described from the Maud Rise and the Gunnerus Ridgc, Antarctica. Two new species of the Desmosomatidae (Eugerdellatinae and Desmosomatinae) are described:Reduetosoma gunneragen. et sp.n. andDesmosoma hesslerasp.n.; one species of the Munnopsidae (Eurycopinae),Disconectes colernunisp.n.; and two species of the Macrostylidae from the Antarctic deep sea,Desmostylis obscurusgen. et sp.n. andMacrostylis sarsisp.n. Comments on the phylogeny and zoogeography are given.

摘要:

Three new Tardigrada species are described from a manganese nodule area of thc abyssal castern South Pacific. Moebjergarctus mangunis gen. et sp.n. is characterized by its segmcntcd ccphalic cirri, club‐shaped and forward bent primary clavae, spherical secondary clavae, spines on legs I, 11, 111, small clavoid papillae on legs IV, long cirri E, and corkscrew‐shaped digits with simple claws. Angursa capsula sp.n. is distinguished by the presence of secondary and tertiary clavac, occurring as elevated cuticular areas, club‐shaped primary clavae, short lateral cirri, short median cirrus, spines on legs I and hcmisphcrical, capsulc‐shaped papillae on legs IV. Angursa lingua sp.n. is characterized by the presence of secondary and tertiary clavae, occurring as elevated cuticular areas, balloon‐shaped primary clavae, long lateral cirri, long median cirrus, spines on legs I, clavoid papillae on legs IV and weakly broadened distal parts of cirri E, resulting in tongue‐shaped swellings. A simple key to the species of Angursa i
