Petrobia Latens
''Petrobia'' is a genus in Tetranychidae (spider mites), containing 34 described species. It includes some pest species. Description ''Petrobia'' mites can be recognised by their reddish-brown cuticle, dark body contents and the first leg pair being very long. Each leg ends in pad-like claws and a hooked (uncinate) empodium with more than 1 pair of tenent hairs. The prodorsum of the body has three pairs of setae (''ve'', ''sci'', ''sce'') and there are no prominent lobes over the gnathosoma. The paranal setae (''h2-3'') are in a ventral position. The genus is usually divided into three subgenera: ''Mesotetranychus'', ''Petrobia'' and ''Tetranychina'' (sometimes one or more of these are considered separate genera). ''Mesotetranychus'' has simple peritremes whereas ''Petrobia'' has anastomosing peritremes. ''Tetranychina'' usually has long dorsal setae on small tubercles (other subgenera sometimes have tubercles as well, but their dorsal setae are short). Reproduction Specie ...
