Diagnosis

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

Etymology

The specific epithet is derived from the name of the ecosystem (páramo) where the specimens were collected. It is treated here as a noun in apposition.

Description

Forebody length 5.3–5.9 mm long. Coloration reddish brown with head and mouthparts slightly darker brown. Head transverse, HW/HL ratio = 1.21. Epicranium with numerous large punctures, except impunctate centre; punctures not contiguous, distance between punctures varies; with faint polygonshaped 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 = 0.88; surface of pronotum with a median impunctate area as wide as 4–5 punctures; with 2–3 rows of disorganized punctures in addition to rows flanking impunctate centre; with faint polygonshaped microsculpture. Elytra shorter than pronotum, EL/PL ratio = 0.79. Elytra with large, deep punctures, distance between punctures equals to width of 0.5–1 punctures; elytra with faint polygonshaped microsculpture. Abdominal terga 3–5 without arch-like carina. Male secondary sexual structures with shallow emargination on sternum 7; with shallow, narrow U-shaped emargination on sternum 8; borders of emargination on sternum 7 and 8 appearing ‘shaved’ (with no setae), but less so than in I. apteros gen. et sp. nov. Aedeagus as in Fig. 4 ; in dorsal view paramere subequal to median lobe; paramere broad, converging to rounded tip; in lateral view paramere more or less straight. Median lobe in dorsal view broad, narrowing to rounded apex; in lateral view median lobe becoming narrower near apex, with small subapical tooth.

Distribution

This species is only known from Iguaque Fauna and Flora Sanctuary (SFF Iguaque) in the Boyacá Department of Colombia ( Fig. 6 ).

Remarks

The holotype is currently in the collection of SEMC but due to the collecting permit requirements (Z. Falin pers. com.), it will be transferred to the IAVH collection in the near future.
