Caerostris Thorell 1868

The genus is known from Africa (9 species) and Asia (2 species). Grasshoff (1984) revised all species and illustrated copulatory organs and somatic characters. He illustrated a third Asian species from Sri Lanka without describing it formally as new. However, no males were known until today from Asia. Present females from Laos are conspecific with the types of C. sumatrana . Differences in copulatory organs and shape of prosoma and opisthosoma are considered the result of intraspecific variation. As the male was found in the vicinity of the locality where females were collected and due to similarities in colouration and sculpturation it is considered conspecific and is described below as male of this species.
