The type genus
Petrobunus Sharma & Giribet, 2011 is derived from
Ancient Greek ‘Pétrā’ (πέτρᾱ), meaning ‘stone’ or ‘pebble’; and
‘-bunus’, a common suffix in Opiliones taxonomy (
e.g. Hadrobunus,
Triaenobunus,
Dibunus). The prefix is in reference to males of this genus, which when seen by eye appear to have pebbles on the proximal fourth leg due to their greatly enlarged trochanter IV. It is also wordplay, as the type species
Petrobunus schwendingeri Sharma & Giribet, 2011 was named in honour of Dr Peter J. Schwendinger (Sharma & Giribet, 2011, p.115), whose given name has the Latin equivalent
Petrus, with the same Greek origins as above (see Sharma & Giribet, 2011, p.111). ==Genera==
