Cothrix n. gen. Reis & Navia

Eriophyidae : Phyllocoptinae : Phyllocoptini ( Figs. 1 & 2 )

Diagnosis. Cothrix n. gen. is a Phyllocoptini species with prodorsal shield not emarginated anteriorly; antapical seta (d) moderately long and bifurcate; coxal seta I (1b) absent; tibial seta (l') on leg I, genual (l") and femoral (bv) seta on legs I and II present; opisthosomal setae d, e and f present; opisthosoma with a longitudinal mid-dorsal ridge and two lateral ridges fading at the level of ventral seta f. This new genus is near to Leipothrix Keifer 1966 ; Mangophyes Chandrapatya and Boczek 2001 and Neodicrothrix Mohanasundaram 1984a , which are all genera belonging to the Phyllocoptini , in possessing the moderately long and bifurcate antapical seta (d). However, it differs from these three genera in the absence of coxal seta I (1b). It also differs from Neodicrothrix in the presence of tibial seta (l') on leg I; from Neodicrothrix and Mangophyes in the presence of genual seta on leg II; from Leipothrix in the presence of femoral seta (bv) on legs I and II; and from Mangophyes and Neodicrothrix in the presence of a middorsal ridge. In Leipothrix , the middorsal ridge fades above seta f, however, in the new genus this ridge extends until the level of this opisthosomal seta.

Type species. Cothrix erugata n. sp.

Etymology. Co, from the Latin cum, meaning with, combined with thrix, Greek feminine meaning hair, referring to the presence of a seta on the femur. The gender is feminine.
