Sewell (1940: 227) described the new species Dactylopusia tropica Sewell, 1940 on the basis of an unspecified number of females. Krishnaswamy (1957: 37) described the hitherto unknown male based on non-type material. Hence, his statement that the “... male allotype will be lodged in the Zoological Survey...” is obviously in violation with the Code (ICZN Art. 72.1.1). Sewell (1940: 229) believed the species formed a “connecting link” between the genera Dactylopusia Norman, 1903a and Dactylopusioides Brian, 1928b. Lang (1965: 168) proposed a new genus Sewellia Lang, 1965 to accommodate D. tropica as its type and only species (by original designation), overlooking that Hora (1932: 315) had already used the same genus-group name for a genus of river loaches (Cypriniformes, Balitoridae). Sewellia Lang, 1965 is therefore a junior homonym of Sewellia Hora, 1932 (type: Balitora lineolata Valenciennes in Cuvier and Valenciennes, 1846, by monotypy). A new replacement name, Sewelliapusia nom. nov. (named after R. B. Seymour Sewell; gender: feminine), is proposed to resolve this case of homonymy and hence the type species should be cited as Sewelliapusia tropica (Sewell, 1940) comb. nov. The genus has remained monotypic since its inception and is currently placed in the family Dactylopusiidae (Willen 2000). [details]
