Etymology: Platygobiopsis: Greek, platys = flat + Latin, gobius = gudgeon + Greek, opsis = appearance (Ref. 45335); tansei: Named 'Tansei' for the research vessel Tanseimaru of the Ocean Research Institute, University of Tokyo (or Japan Marine Science and Technology Center) for collecting many Suruga Bay specimens including the holotype; noun in apposition.
Eponymy: ‘Tansei Maru’ is the name of a research vessel, owned by the Ocean Research Institute, University of Tokyo (now Japan Marine Science and Technology Center), which was responsible for collecting the holotypes of the goby and false brotula. (Ref. 128868), visit book page.

Các tia vây lưng cứng (tổng cộng) : 7; Các vây lưng mềm (tổng cộng) : 13 - 14; Tia cứng vây hậu môn: 1; Tia mềm vây hậu môn: 12 - 14; Động vật có xương sống: 26. This species is distinguished by the following characters: D VI, I, 13-14; outer gill rakers on first gill arch 0+9-10; no chin barbel; predorsal scales reaching anteriorly to transverse line through middle of operculum; no scales from pectoral-fin base; cephalic sensory-canal pores absent; pelvic-fin frenum absent (Ref. 75206).
A true benthic species in the sloping sandy mud bottoms, often residing in the bottom sediment itself. In Suruga Bay, P. tansei was often found in beam trawl collections containing a lot of sandy mud sediments, probably due to the less than flat bottom configuration of the habitat (Ref. 75206).
