Melanastera ingariko Serbina & Malenovský & Queiroz & Burckhardt 2025

The ingariko -group Description. Adult. Head, in lateral view, inclined at ≥ 45° from longitudinal axis of body (Fig. 7F).Vertex trapezoidal, covered with distinct imbricate microsculpture (Figs 11I, J, 12A, C–E) (rugosely imbricate in M. acuminata sp. nov.; Fig. 12B) and microscopical setae. Thorax moderately or strongly arched, covered with microscopical setae; metapostnotum usually with distinct longitudinal keel (indistinct in M. caramambatai sp. nov.). Forewing (Fig. 18C–I) uniformly coloured, with small brown dots; pterostigma distinctly expanding towards the middle or apical third, longer than 4.0 times as wide; vein R 1 weakly convex or straight medially. Paramere, in lateral view, irregularly acuminate, falcate or lamellar. Distal segment of aedeagus bearing short ventral process, less than half as long as apical dilation, which is, in dorsal view, wider than the latter. Immature. Antenna 10-segmented. Comments. The group comprises seven species from Brazil and one species from Panama, viz. M. longitarsata (Brown & Hodkinson). The Panamanian species differs from the other group members in the longer metatibia (MT/ MF> 1.7 versus ≤ 1.7). Five species develop on Melastomataceae (Clidemia, Miconia) and two on Annonaceae (Guatteria, Xylopia).
