Onomastus

Onomastus is a genus of Asian jumping spiders (family Salticidae) that was first described by Eugène Louis Simon in 1900.[2] It is the only genus in the subfamily Onomastinae.[3]

Description

Onomastus species are delicate, translucent spiders, with long legs compared to most other members of the family Salticidae. Males have highly complex palpal bulbs. Two clades have been distinguished: in species from Southeast Asia, the palpal bulb has a broad conductor; in those from South Asia it has a medial branch on the median apophysis. Like species of the subfamilies Lyssomaninae and Asemoneinae, the anterior lateral eyes form a separate row from the anterior median eyes.[3] The genus was originally diagnosed on the basis of the arrangement of the eyes.[2]

Taxonomy

The genus Onomastus was first described by Eugène Simon in 1900. He placed it in the "Attidae",[2] the name he then used for the family Salticidae. It was later placed in a broadly defined subfamily Lyssomaninae, although by the 1980s it was agreed that this subfamily consisted of three groups.[4] When Wayne Maddison divided the subfamily into three in 2015, the genus was placed in its own subfamily, Onomastinae.[3]

Species

As of August 2019, it contains fifteen species, found only in Asia:[1]
