DIAGNOSIS. — Body spindle; prodorsal shield with frontal lobe; dorsal pedipalp genual setae (d) bifurcate; scapular tubercles ahead of rear shield margin; scapular setae (sc) directed mediad; coxae with sternal line; anterolateral setae on coxisternum I (1b) absent, leg with usual segments and setae; empodium divided, dorsal opisthosoma with three ridges, middorsal ridge ending in a broad furrow before the termination of subdorsal ridges; opisthosoma with all usual setae.
REMARKS
The new taxon is assigned to Eriophyoidea, Eriophyidae, Phyllocoptinae, Acaricalini.The new genus is similar to Acaphyllisa Keifer, 1978, but can be differentiated by anterolateral setae on coxisternum I (1b) absent (anterolateral setae on coxisternum I [1b] present in Acaphyllisa; see Keifer 1978). The new genus is also similar to Acaphylla Keifer, 1943 and Paracaphyllisa Kuang & Luo, 2004, but can be differentiated by anterolateral setae on coxisternum I (1b) absent and antaxial genual setae (l’’) of leg II present (anterolateral setae on coxisternum I [1b] present in Acaphylla and antaxial genual setae [l’’] of leg II absent in Acaphylla and Paracaphyllisa; see Keifer 1943; Kuang & Luo 2004).
