Erythmelus (Erythmelus) reductus S. Triapitsyn, 2003

( Figs 69–71 )

Erythmelus (Erythmelus) reductus S. Triapitsyn 2003: 21–24 (holotype female [Humboldt University, Villa de Leyva , Boyacá, Colombia], examined. Type locality: Parque Nacional Natural Amacayacu, 3.82ºS 70.26ºW, Amazonas, Colombia).

Diagnosis. Erythmelus (E.) reductus was only provisionally assigned to the flavovarius species group by Triapitsyn (2003); indeed it most probably belongs in there. The original description of this species is detailed and well-illustrated, so it is not repeated here. The male of E. (E.) reductus has a 9–segmented antennal flagellum ( Fig. 71 ), unlike in all other described species of subgenus Erythmelus (Erythmelus) , which have an 11– segmented or, rarely, a 10–segmented flagellum (males are not known in many species). The female of E. (E.) reductus is somewhat similar to that of E. (E.) cingulatus Ogloblin and differs from the latter by a narrower (5.5–5.9 x as long as wide), strongly infuscate forewing ( Fig. 70 ) with a different chaetotaxy of the blade and longer marginal cilia relative to the greatest width of the wing (the forewing of E. (E.) cingulatus is 4.5–4.7 x as long as wide). F2–F4 of the female antenna of E. (E.) reductus ( Fig. 69 ) are longer than wide.

Distribution. Colombia ( Triapitsyn 2003)

Hosts. Unknown.
