Eibesfeldtphora digitata Brown new species

Fig. 2 .

Diagnosis. This species differs from others by the apically narrowed foretarsomere 5 with its greatly reduced claws. It further differs from other species with laterally flattened dorsal and ventral processes of the oviscape by their ventral curvature and relatively narrow size. In the key of Brown (2001), E. digitata keys to E. isomorpha (Brown) at couplet 8. It differs, however, in that the lateral processes of the oviscape are much smaller, less rounded and slightly ventrally curved. In E. isomorpha , the processes project straight posteriorly, are broad, and broadly rounded (compare with Brown 2001: figure 19).

The more recently described E. saltensis Disney is also somewhat similar, but has a broader dorsal lobe, and a much shorter ventral lobe (compare with Disney et al. 2009: figure 2).

Description. Female. Body length 2.2 mm. Apex of foretarsomere 5 narrowed, claws reduced. Costa 0.50 wing length. Oviscape with two well separated processes; dorsal process dorsoventrally flattened in posterior view, slightly ventrally curved; ventral process short, small, laterally flattened.

Derivation of specific epithet. Named for the fingerlike lobes of the oviscape.

Holotype. Ƥ, Brazil: Espírito Santo: São Mateus, i.2009, M. Bragança [barcode: LACM ENT 305108] (MZSP).
