03C187F8091FF4456AC467CFFA0DFBC6.taxon	materials_examined	Type species: Gangliostoma guangdongensis Xu, 1983. Diagnosis. The genus is diagnosed by following: medusa with many simple radial canals; subumbrella without radial rows of gelatinous papillae; manubrium with radial rows of gelatinous papillae. Remarks. It comprises three species: G. dayaensis Xu, Huang & Du, 2010, G. guangdongensis Xu, 1983 and G. abaxialispura Xu, Huang & Guo, sp. nov., which are known in China seas.	en	Guo, Donghui, Xu, Zhenzu, Huang, Jiaqi, Wang, Chunguang, Lin, Mao (2019): Two new hydrozoan species from the Taiwan Strait, China (Cnidaria: Hydrozoa: Leptothecata).

03C187F8091CF4466AC466C5FACCFBD3.taxon	materials_examined	Type materials. Holotype (TIO 032), China, south of Taiwan Strait, Station ZD-MJK 535 (26 ° 09 ’ N, 120 ° 45 ’ E), depth 67 m, sampling depth 67 – 0 m, 20 July 2006, coll. Peng Xiang. Diagnosis. The species is diagnosed by following: umbrella nearly disk shaped, apex jelly very thick; manubrium very broad, with a basal circular row of as many papillae as radial canals; with 8 marginal tentacles, tentacular bulbs with a distinct abaxial spurs upwards over margin of bell; with 6 rudimentary bulbs and 6 statocysts between the tentacles. Description. Umbrella 5.0 mm in height, 8.0 mm in width, nearly disk shaped, apex jelly very thick, thinning towards margin; with very broad manubrium which devoid of a peduncle, about half as wide as diameter of umbrella, with a basal circular row of as many as papillae as radial canals; without subumbrella gelatinous papillae; with 32 simple radial canals, oral lips short, less numerous than radial canals; gonads extending along whole length of radial canals, but not connected to ring canal; with 8 well-developed hollow marginal tentacles, about 1 / 4 as many as number of radial canals, tentacular bulbs large, nearly spherical-like with a distinct abaxial spurs upwards over margin of bell; no ocelli; with 6 rudimentary bulbs between tentacles, medium one larger than other two or three; with many statocysts of same number as rudimentary bulbs; velum broad. Distribution. Taiwan Strait, China. Etymology. The specific name derived from the Latin abaxialispura, meaning abaxial-spur, in reference to the morphology of tentacular bulbs with an abaxial spur. Remarks. This new species has following characters which are in common with Gangliostoma Xu, 1983: medusa with a very broad manubrium, with a basal circular row of papillae of the same number as the radial canals. Before the work, only two species of Gangliostoma, G. dayaensis and G. guangdongensis, are known (Xu, 1983; Bouillon et al., 2006; Du et al., 2010; Xu et al., 2014). The new species can be distinguished from other two by following: 1) umbrella with 8 marginal tentacles, about 1 / 4 as many as the number of radial canals; 2) each tentacular bulbs with a distinct abaxial spurs, without excretory papillae; 3) with 6 rudimentary bulbs and 7 statocysts between the tentacles.	en	Guo, Donghui, Xu, Zhenzu, Huang, Jiaqi, Wang, Chunguang, Lin, Mao (2019): Two new hydrozoan species from the Taiwan Strait, China (Cnidaria: Hydrozoa: Leptothecata).

03C187F8091CF4476AC46256FEDDFB65.taxon	materials_examined	Type species: Eutima mira McCrady, 1859. Diagnosis. The genus is diagnosed by following: medusa with a distinct gastric peduncle; with lateral cirri and marginal warts; mouth with simple lips; 4 simple radial canals; gonads on radial canals, either beneath subumbrella or gastric peduncle or on both; with 8 (exceptionally 12) statocysts. Remarks. Members of the genus are easily distinguished from all other genera by their medusa with 8 statocysts; with lateral cirri on marginal warts and marginal tentacles. The genus comprises 20 valid species (including the new species) (Mayer, 1910; Kramp, 1961; Bouillon, 1984; Bouillon et al., 2006; Guo et al., 2008; Xu et al., 2014), of which only 13 species are known in China seas.	en	Guo, Donghui, Xu, Zhenzu, Huang, Jiaqi, Wang, Chunguang, Lin, Mao (2019): Two new hydrozoan species from the Taiwan Strait, China (Cnidaria: Hydrozoa: Leptothecata).

03C187F8091DF4406AC462FFFB2AFEC3.taxon	materials_examined	Type materials. Holotype (TIO 033) and paratype (TIO 034 – 040), China, Taiwan Strait, Station ZD-MJK 571 (24 ° 59 ’ N, 120 ° 28 ’ E), depth 80 m, sampling depth 79 – 0 m, 29 July 2006, coll. Peng Xiang. Diagnosis. The species is diagnosed by following: umbrella almost hemispherical, apex jelly thick; with a distinct gastric peduncle; with 12 (rarely 16) tentacles without lateral cirri, with 80 – 120 marginal warts with lateral cirri; with 8 gonads, 4 subumbrellar gonads sinuous-like, 4 peduncular gonads near proximal end of peduncle. Description. Umbrella 5.0 – 6.0 mm in height, 8.5 – 12.0 mm in width, almost hemispherical, apex jelly thick, thinning towards margin; with a distinct gastric peduncle, long, tapering manubrium small, about as long as bell diameter, about 2 / 3 exceeding bell opening; manubrium short and thick, cross-shaped in transversal section; mouth with 4 simple, long lips with crenulated margin; with 8 gonads on radial canals, 4 subumbrellar gonads, elongated sinuous-like extending from nearly bell margin to basal part of peduncle, other 4 peduncular gonads extending from middle part of peduncle to manubrium; usually 12 long hollow marginal tentacles, rarely 16, 4 perradial, 8 adradial, with elongated conical basal marginal bulbs, laterally compressed, without lateral cirri; with 80 – 120 marginal warts, each with 1 pair of lateral cirri; 4 simple radial canals running from circular canal across underside of bell along peduncle to manubrium; 8 adradial statocysts; velum broad. Distribution. Taiwan Strait, China. Etymology. The specific name of the new species is referring to its type locality, the Taiwan Strait, China. Remarks. The new species has following features: a distinct gastric peduncle; with 8 statocysts (rarely 12); marginal tentacles without lateral cirri; marginal warts with lateral cirri; without excretory papillae; gonads on radial canals, which in accordance with the genus Eutima of Eirenidae. At present, 20 valid species in Eutima (including this new species) are known (Bouillon et al., 2006; Xu et al., 2014). This new species can be easily distinguished from the other species of Eutima by 8 gonads, 4 on subumbrella and 4 on peduncle; marginal tentacles without lateral cirri. It is similar to E. hartlaubi Kramp, 1958, but differs from the latter by following: 1) E. taiwanensis with 80 – 120 marginal warts with lateral cirri, and E. hartlaubi with 32 marginal warts with lateral cirri; 2) E. taiwanensis with 4 subumbrellar sinuous gonads, 4 peduncular gonads near proximal end of peduncle; and E. hartlaubi with 4 subumbrellar linear gonads, 4 peduncular gonads in middle part of peduncle.	en	Guo, Donghui, Xu, Zhenzu, Huang, Jiaqi, Wang, Chunguang, Lin, Mao (2019): Two new hydrozoan species from the Taiwan Strait, China (Cnidaria: Hydrozoa: Leptothecata).
