Redescription of Homaloptera stephensoni

This taxon was first described by Hora (1932) based on a single specimen obtained from the upper Mahakam basin in East Kalimantan. Hora re-identified the taxon that Popta (1905, 1906) had earlier listed as Helgia modesta Vinciguerra (a species described from Myanmar). This name had subsequently been used for populations identified from other localities in Borneo. Because of its poor original definition and illustration, this unique type specimen is herein re-described together with fresh comparable material from Central Kalimantan. The re-description may provide a basis for further comparative work with the other populations of Homaloptera in Borneo.
