Diagnosis

Among species of Ikaros gen. nov. that lack arch-like carina on terga 3–5, I. apteros gen. et sp. nov. lacks any punctures on the pronotum, beyond the punctures along the median area, whereas I. paramo gen. et sp. nov. has punctures arranged in multiple rows.

Etymology

The specific epithet is derived from the Greek word ‘άπτερος’ (‘without wings’) and refers to the lack of hind wings. It is treated here as a noun in apposition.

Description

Forebody length 7.1 mm long. Coloration reddish brown with head and mouthparts slightly darker brown. Head transverse, HW/HL ratio = 1.18. Epicranium mostly impunctate, with few large punctures posteriorly, medially and around margin of head and eye; with faint polygon-shaped microsculpture. Labial palpus with palpomere 3 widest apically, subparallel-sided. Antennomeres with crown-like macrosetae shorter than length of antennomere. Pronotum longer than wide, PW/PL ratio = 0.91; surface of pronotum impunctate except two punctures on each side of median area and few punctures around margin; with faint polygon-shaped microsculpture. Elytra shorter than pronotum, EL/PL ratio = 0.75. Elytra with large, deep contiguous punctures and dense polygon-shaped microsculpture.Abdominal terga 3–5 without arch-like carina. Male secondary sexual structures with shallow but broad emargination on sternum 7; with deep, broad V-shaped emargination on sternum 8; borders of emargination on sternum 7 and 8 appearing ‘shaved’ (with no setae). Aedeagus as in Fig. 3; in dorsal view paramere longer than median lobe; converging to elongate, narrow tip; apex of paramere with small emargination; in lateral view paramere concave, becoming narrower. Median lobe in dorsal view narrowing to rounded apex; in lateral view median lobe becoming narrower near flattened apex, with no subapical tooth.

Distribution

Known from the National Park Chingaza in the department of Cundinamarca, Colombia (Fig. 6). The holotype was collected in the Republic of New Granada (1831–1858), which refers to a region that included primarily Colombia and Panama, and smaller areas from the countries of Brazil, Costa Rica, Ecuador, Peru and Venezuela.
