Sinoecetes Ren, 2012 Siphonoecetini Just, 1983 (Crustacea, Amphipoda, Ischyroceridae) 13: Western Australian species of Bubocorophiina in Rhinoecetes, Cephaloecetes, Sinoecetes, Borneoecetes and Pararhinoecetes gen. nov. Just, Jean Zootaxa 2019 2019-02-08 4554 1 101 140 7PZV6 Ren, 2012 Ren 2012 [151,409,151,178] Malacostraca Ischyroceridae Sinoecetes GBIF Animalia Amphipoda 31 132 Arthropoda genus    Sinoecetes Ren, 2012, diagnosis in Chinese p. 68; diagnosis in English p. 537.   Remarks. A defining characteristic of  Sinoecetes( typeand hitherto only species  Sinoecetes sinensis Ren, 2012, fig. 29) within the Bubocorophiinais the lack of uropod 2. This is shared by the six species of north and northeast Australian  Belkginoecetes Just, 2012b. However,  Sinoecetesdiffers from  Belkginoecetesin possessing a single round ramus on uropod 3 (ramus absent in  Belkginoecetes), and a head with pseudorostrum instead of a true frontmargin derived rostrum. The latter character is not mentioned in Ren’s diagnosis or description, nor illustrated in his dorsal view of the head.  Sinoecetes sinensismay have the same head characteristics, but differences in magnification and hence rendition may have prevented Ren seeing the thin, semitransparent front margin overhanging the pseudorostrum. In his description of  Sinoecetes sinensisRenstates “flagellum [of antenna 2] 2- articulated, ventrodistal end of article 1 with 2 spines, ventral margin of article 2 with 2 spines”. If correct, this would be the only one of the about 85 species in the tribe to exhibit such fusion of the normal 4 segments. Until reassessed I do not consider this in assigning the new species to  Sinoecetes Ren, 2012.
