Sagittacopula, new genus, is described to accommodate S. rufescens, new species, from Cape

Many species of Orthotylinae of New and relatively long metathoracic legs. In the

a shining glassy body, an anteroventrally species originally described by Carvalho

gracile appendages. This morphology is epit- Candidomiris-group.
