Thenew species is a member of the S. paraneptunus Coutiere species complex and is distinguished from other species in that group by the combination of four carpal segments in the second pereopod, uropodal exopod with 2nd disto-lateral tooth smaller than theother two teeth and set in line with movable spine, and a small blade on the scaphocerite. Synalpheus microneptunus n. sp. is the smallest species in the complex (2.2-2.9 mm CL) and lives in small colonies, usually with fewer than 10 individuals, oftenwith a single breeding female. Synalpheus thele Macdonald, Hultgren & Duffy is reported for the first time from outside its type locality in Jamaica. Sampling in Barbados produced fewer species than did similar efforts in Jamaica and Curacao, possibly due to the relatively isolated position of the island at the eastern (windward) edge of the Caribbean Sea.

Specimens, previously attributed to these species, from Amazonia, South Africa, and Bali, were also examined and proved to belong tothree species new to science: Doryphoribius amazzonicus sp. nov., Doryphoribius bindae sp. nov., and Doryphoribius solidunguis sp. nov. Doryphoribius amazzonicus sp. nov. has a reticular cuticular ornamentation with ridges forming a tubercle at each crossing; legs lacking cuticular ornamentation; buccal tube slightly longer than in D. flavus with respect to the body length, stylet supports inserted on the buccal tube in a slightly more caudal position; peribuccal papulae present; teeth and ridges appearto be absent in the buccal cavity; pharyngeal bulb with apophyses and two macroplacoids; claws slightly shorter and stouter than in D. flavus. Accessory points and smooth lunules present. No other cuticular thickening present on the legs. Doryphoribiusbindae sp. nov. has a delicate reticular cuticular ornamentation formed by narrow ridges with a tiny tubercle at each crossing; a fine reticular design present on the legs; peribuccal papulae present, buccal armature with only one dorsal tooth near the medial margin of each stylet sheath. Pharyngeal bulb with apophyses and two macroplacoids. Accessory points and small lunules present. No other cuticular thickening present on the legs. Doryphoribius solidunguis sp. nov. has a very obvious reticular cuticular ornamentation with an irregular shape and size mesh (usually large) delimited by thick, sometimes protruding ridges that may form tubercles at crossings; cuticle of the legs smooth; peribuccal papulae present and two pairs of dorsal teeth lying along the anterior margins of the stylets sheaths. Pharyngeal bulb with apophyses and two macroplacoids. The claws are large and stout with very small accessory points; lunules present, those of the inner claws more evident than in similar species; a cuticular bar is present on the first three pairs of legs. Doryphoribius flavus was considered widespread, but this work exposing cryptic species indicates that the geographic distribution is more restricted.

It differs from all other congeners by the presence of symmetrical or subsymmetrical reticulations on top of head; no nuchal loop; four precloacal pores separated medially by one poreless scale; 14-18 enlarged femoral scales beneath thighs continuous with precloacal scales; four to six irregular, narrow, yellowish-white bands on dorsum between limb insertions; and six or seven incomplete white rings on tail.
查看更多>>摘要:This paper reports the description of two new species belonging to the family Linotetranidae from Iran, Linotetranus iraniensis sp. nov. and L. astragalusi sp. nov., collected in soil associated with gum bushes, Astragalus gossypinus Fisch. (Fabaceae). A key to all known species of the world is provided. Linotetranidae differs from the other four families of the superfamily Tetranychoidea due to the presence of ventral setae 2a and the absence of eyes (Baker & Pritchard 1953; Beard & Walter 2004). The genus Linotetranus was established by Berlese (1910) and it was promoted to the family Linotetranidae by Baker & Pritchard (1953). Currently this family has four genera, namely: Afrolinotus Meyer & Ueckermann, Anoplopalpus Meyer & Uecker-mann, Austrolinus Beard & Walter and Linotetranus Berlese. Linotetranus is the largest genus and based on phylogenetic data is most closely related to Anoplopalpus (Beard & Walter 2004).
查看更多>>摘要:Two new species of the genus Stenohya are described from China: Stenohya curvata sp. nov. from Yunnan Province and S. xiningensis sp. nov. from Qinghai Province, China. Detailed diagnosis, descriptions and illustrations of the two new species are presented. The genus Stenohya was erected by Beier (1967), who assigned it to the family Hyidae Chamberlin, 1930. It remained there until it was transferred to Neobisiidae Chamberlin, 1930 by Harvey (1991a). In the same article, Harvey also synonymized Levigatocreagris Curcic, 1983 with Stenohya Beier, 1967. The genus Stenohya includes ten species at present (Harvey 1991b, 2009): S. gruheri (Curcic, 1983) and S. martensi (Schawaller, 1987) from Nepal; S. hamata (Leclerc & Mahnert, 1988) and S. mahnerti Schawaller, 1994 from Thailand; S. kashmirensis (Schawaller, 1988) and S. caelata (Callaini, 1990) from India; S. vietnamensis Beier, 1967 (type species) from Vietnam; S. lindbergi (Beier, 1959) from Afghanistan; S. hems (Beier, 1943) from Central Asia; andS. chinacaver-nicola Schawaller, 1995 from China.

Consistent with Article 73.2.3 of the International Code of Zoological Nomenclature (Anonymous 1999), the Syntype specimens of C. modesta originated from two localities and thus the type locality "encompasses all of the places of origin. Moore (1898) synonomized C. modesta with the European Helobdella stagnalis (Linnaeus 1758) based on similaritiesin morphology. Subsequently, all North American leeches with a nuchal scute were considered as H. stagnalis with the exception of Helobdella californica Kutschera 1988, known only from Stow Lake, Golden Gate Park, San Francisco, California, USA. In addition to Europe and North America, Helobdella stagnalis has been reported from South America, Africa, and Asia (Sawyer 1986).
