Phyllodiaptomus wellekensae n. sp. is described from south India. In the female, the genital somite is dilated at the left proximal margin and armed with an extraordinarily large, somewhat curved, laterally-directed spine; the right genital spine is much smaller than the left one. The terminal claw of leg 5 has a secretory pore at its tip and a characteristic conveyor canal on its anterior surface. In the right male P5, the coxal plate is short and unique in shape. The basis is 1.3 times as long as wide, with a long, sinuous, hyaline lamella on its medial margin. The first exopodite segment is short and optuse at its outer distal corner. The second segment is rectangular and has a short, hyaline, spinous projection between the lateral spine and the terminal claw. The left P5 has a large, serrate, hyaline fan between its apical thumb and medial apical seta.P. tunguidus is redescribed based on material newly collected from three localities in China. 相似文献

The morphology and infraciliature of a new hypotrichous ciliate, Euplotidium smalli n. sp., isolated from eutrophic coastal water in Korea, were observed in living cells and investigated using the protargol impregnation technique. This new ciliate bears 13-14 frontoventral cirri, 7 transverse cirri, and 5-6 dorsal kineties. Neither left marginal cirrus nor caudal cirrus is present. The new species differs from the related species, Euplotidium agitatum Noland, 1937 in the different number of frontoventral and transverse cirri and different body shape. With the exception of Euplotidium agitatum, the known species of the genus Euplotidium Noland, 1937 with the presence of left marginal cirrus are assigned to a new genus, Paraeuplotidium n. g. Diagnosis of Paraeuplotidium is: Gastrocirrhidae with funnel-shaped buccal cavity; with frontoventral and transverse cirri; left marginal cirrus present. Paraeuplotidium itoi (Ito, 1958) n. comb. is designated here the type species. Four additional species are included: Paraeuplotidium psammophilus (Vacelet, 1961) n. comb., Paraeuplotidium arenarium (Magagnini & Nobili, 1964) n. comb., Paraeuplotidium helgae (Hartwig, 1980) n. comb., and Paraeuplotidium prosaltans (Tuffrau, 1985) n. comb. An improved generic diagnosis of Euplotidium is suggested based on morphology and infraciliature characters: marine hypotrichs with a funnel-shaped buccal cavity; with frontoventral and transverse cirri; neither left marginal cirrus nor caudal cirri present. 相似文献

Two new marine diatom species from Argentinean coastal waters, Pleurosigma hinzianum Sterrenburg, Sunesen & Sar, sp. nov. and P. frenguellianum Sunesen, Sterrenburg & Sar, sp. nov., are described. The characters permitting their identification are specified, based on comparison with type material of the morphologically similar species P. amara Stidolph and P. elongatum W. Smith in the light (LM) and scanning electron microscope (SEM). New information on the type material of P. elongatum is presented and its taxonomic concept is emended. The main criteria for separation of the species discussed here are: valve outline, path of the raphe-sternum, raphe angle and angle of intersection of the oblique striae in LM; and external central and terminal raphe fissures, internal details of the central area, external and internal apical structure, and morphology of the hymen-occluded internal pores in SEM. The occurrence of these (and probably other) species in the genus Pleurosigma in net samples is adventitious and not indicative of a true planktonic mode of life. 相似文献

通过测定中国产罗布红麻、大叶白麻和白麻的ITSt、rnL内含子和trnL-F非编码区序列,并与其它相关植物的相应序列比较,探讨“罗布麻”的系统分类。结果显示:罗布红麻、大叶白麻和白麻3种植物的ITS序列完全一致,而与罗布麻属加拿大麻的ITS序列相差较大;在trnL内含子和trnL-F非编码区,大叶白麻和白麻的完全一致,与罗布红麻之间仅有3个位点的变异,而加拿大麻与美国茶叶花在这3个位点却和白麻属的完全一致等。以上结果显示在ITSt、rnL内含子和trnL-F非编码区,白麻属和罗布麻属之间没有本质区别,罗布红麻与大叶白麻和白麻之间的亲缘关系可能较罗布红麻与罗布麻属内其它物种间的亲缘关系更近。遗传距离与系统树的分析结果进一步支持以上推论。建议撤销白麻属,将大叶白麻和白麻合并到罗布麻属。 相似文献
