Anisophyllodes candango sp. n.

( Figures 30–40 )

Type material

Male holotype, two male and six female paratypes from the Lesser Elaenia , Elaenia chiriquensis Lawrence, 1865 ( Passeriformes , Tyrannidae ), Fazenda Agua Limpa, Brasília, D.F., Brazil (15 ° 579S, 47 ° 569W); 9 August 2002, coll. M. F. Kanegae. Holotype and paratypes are deposited at CAIOC; a paratype female and male are deposited at DZSJRP.

Differential diagnosis

Among two formerly known species, the new species is morphologically similar to Anisophyllodes intermedius . The males of A. candango differ from A. intermedius by relatively wider idiosoma, with the ratio of length to width about 1.9–2, and by the rounded lateral extensions bearing bases of setae h2; the females are distinguished by significantly wider terminal cleft, which is 1.2–1.3 times longer than wide. In the males of A. intermedius , the idiosoma is much narrower, 2.5–2.7 times longer than wide, and the lateral extensions of the opisthosoma bearing setae h2 are acute apically; in the females, the terminal cleft is long and narrow, 3.5–4 times longer than wide.

Etymology

The specific epithet derives from candango (African origin), a common name meaning those who live, but were not actually born in Brasilia (the capital of Brazil), the type locality of this mite species; the name is a noun in apposition .
