Redescription of Homaloptera tateregani

This taxon was first described by Popta (1905) based on a single specimen obtained from the upper Mahakam basin in East Kalimantan. It had not been subsequently reported upon, except by Silas (1952), who included it in a new genus, Pseudohomaloptera, based primarily on the presence of postrostral grooves, which should correctly be termed postoral grooves. However, upon comparison with the present series and other congeners, I consider this character unreliable: it could be a preservation artifact. In the fresh series of H. batek described above too, this postoral groove is present: it is thus not unique to H. tateregani . Further, it is premature to split the genus Homaloptera without a well-supported phylogenetic hypothesis.
