Solivagus Reis & Navia , n. gen.

Diptilomiopidae , Rhyncaphytoptinae ( Figs. 1–2 )

Diagnosis. Solivagus n. gen. is a Rhyncaphytoptinae genus with coxal seta I (1b) absent; prodorsal shield with scapular setae (sc) absent, however, scapular tubercles present, minute, with longitudinal bases and near rear shield margin; tibial seta (l’) on leg I present; genual setae (l’’) absent in leg II and femoral seta (bv) absent on legs I and II. This new genus is near Sakthirhynchus Umapathy & Mohanasundaram, 1999 ; Chakrabartiella Amrine & Stasny, 1994 and Hyborhinus Mohanasundaram, 1986 of the Rhyncaphytoptinae in the absence of coxal seta I (1b). However, it differs from these genera especially in the chaetotaxy of the legs and prodorsal shield. It varies from Sakthirhynchus in the presence of genual seta (l’’) and tibial seta (l’) on leg I and prodorsal shield tubercles, all absent in Sakthirhynchus ; from Chakrabartiella in the absence of genual seta (l’’) on leg II and of scapular setae (sc), both present in Chakrabartiella ; and from Hyborhinus , in the absence of femoral seta (bv) on legs I and II, genual seta (l’’) on leg II and of scapular seta (sc), all present in Hyborhinus .

Type species. Solivagus alpha n. sp.

Etymology. The generic name, Solivagus , is derived from the Latin words solus or solitarius, which means alone or solitary and the Latin word vagus, which means wandering, and refers to the vagrant habit of the mite. Gender: masculine.
