Echinogammarus Hou & Sket, 2016, S. STR.
No full text(ECHINOGAMMARUS S. STR.) Echinogammarus in a revised sense was previously named Echinogammarus berilloni group by Pinkster (1973, 1993) and Atlantic Echinogammarus by Hou et al. (2014). Its type species is Gammarus berilloni Catta, 1878. Diagnosis South-west European gammariform amphipods similar to Homoeogammarus, but pereon smooth, pleonites with prominent, numerous, and irregularly disposed stout spines (spiniform setae), and/or tufts of long setae dorsally or/and laterally; no keels or teeths. Gnathopod propodus II longer than propodus I. Uropod III exopodite well developed, biarticulate, with marginal spines and long, straight setae.Published as part of Hou, Zhonge & Sket, Boris, 2016, A review of Gammaridae (Crustacea: Amphipoda): the family extent, its evolutionary history, and taxonomic redefinition of genera, pp. 323-348 in Zoological Journal of the Linnean Society 176 (2) on page 330, DOI: 10.1111/zoj.12318, http://zenodo.org/record/535755
Trichogammarus Hou & Sket 2016, GEN. NOV.
No full textGENUS TRICHOGAMMARUS GEN. NOV. Type and the only known species Chaetogammarus trichiatus Martynov, 1932 (syn. Chaetogammarus tenellus major Caraus ¸u, 1943). Etymology Named after its hairy uropod III; in ancient Greek thríks, trikhós = hair. Distribution Chaetogammarus trichiatus inhabits affluents of the Black Sea only. Remarks Although very similar to both Chaetogammarus and Homoeogammarus, it can be distinguished by the characteristic setosity of uropod III. Phylogenetically, this clade is also nested within the Ponto-Caspian group, distant from Homoeogammarus, but very close to the Dinaric clade of Homoeogammarus.Published as part of Hou, Zhonge & Sket, Boris, 2016, A review of Gammaridae (Crustacea: Amphipoda): the family extent, its evolutionary history, and taxonomic redefinition of genera, pp. 323-348 in Zoological Journal of the Linnean Society 176 (2) on page 335, DOI: 10.1111/zoj.12318, http://zenodo.org/record/535755
Gammarus tianshan Zhao, Meng & Hou, 2017, nom. nov.
No full textGammarus tianshan nom. nov. = G. montanus Hou et al., 2004, in Hou et al., 2004: 257 –284, figs 1–5. Etymology. The specific name is a noun in apposition, derived from the type locality. Diagnosis and description. see Hou et al., 2004. Remarks. Hou et al. (2004) established a new species of the genus Gammarus based on specimens from Tianshan Town, Xinjiang Province, China, Gammarus montanus, whose name is invalid as it has been previously used for Gammarus pavlovici montanus Karaman, S., 1929 from Skopska Crna Gora, Macedonia. Although Gammarus pavlovici montanus Karaman, S., 1929 was synonymized with Gammarus balcanicus Schäferna, 1922 (Karaman 1977, Karaman & Pinkster 1987), it may be a valid taxon based on molecular analysis (Mamos et al. 2016). Consequently, a new species name, Gammarus tianshan nom. nov. is proposed for Gammarus taxon from Tianshan Town, Xinjiang Province, China.Published as part of Zhao, Shuangyan, Meng, Kaibaryer & Hou, Zhonge, 2017, Two new Gammarus species and a new name (Crustacea: Amphipoda: Gammaridae) from Northwest China, pp. 195-215 in Zootaxa 4273 (2) on page 196, DOI: 10.11646/zootaxa.4273.2.3, http://zenodo.org/record/80192
