Diagnosis

According to the original description, the male of M. eduardoi  can be distinguished from all congeners by the following combination of characteristics: 1) fore wing translucent, with costal and subcostal area tinged with grey and with longitudinal vein CuP absent; 2) penes opaque yellow, spine elongate with lateral projections.

Description

Female subimago ( Fig. 2View Fig. 2 B)

LENGTH (mm). Body: 3.0–4.8; fore wing: 3.2–5.0. General coloration dark brown and yellowish.

HEAD. Brown, washed with black; area between lateral ocelli and posterior margin tinged with black.

FORE WING. Membrane white, longitudinal and cross-veins black; vein CuP absent.

ABDOMEN. Translucent (yellow because of the presence of eggs), washed with black; terga II –V forming a V-shaped unpigmented area; caudal filaments broken off.

Egg ( Fig. 4View Fig. 4 E)

Yellow. Shape elongate. One polar cap present. Chorion with longitudinal costae formed by plates, each one with a deep emargination.

Remarks

In the description of the male imago of M. eduardoi  there is no reference to the presence of membranous filaments of the mesoscutellum; this character is evident from the fresh material studied here. After examining the holotype of M. eduardoi  it was possible to observe the presence of a short filament of about ¼ the length of the mesoscutellum. According to the original description, the hook-shaped lateral expansions present in the penis projection are distributed from its base to the middle region, whereas in the material examined by us the expansions are present throughout the penis projection, decreasing in size towards the apex. This is the first record of M. eduardoi  from southeastern (state of Espírito Santo) and northern (state of Amazonas) Brazil.

Macunahyphes eduardoi  occurs in areas comprising two disjunct biomes, Amazon and Atlantic Forest. Other species of plants and animals also show this distribution pattern, including some aquatic insects, such as Asthenopodes chumuco Molineri, Salles & Peters, 2015  ( Ephemeroptera  : Polymitarcyidae  ), Macrostemum erichsoni (Banks, 1920)  and Smicridea (Ryachophylax) roraimense Albino, Pes & Hamada, 2011  ( Trichoptera  : Hydropsychidae  ). The presence of disjunct populations of a single taxon in Amazonia and the Atlantic Forest may be evidence of ancient connections between these biomes (see Costa 2003; Santos et al. 2007; Fiaschi & Pirani 2009; Buso Junior et al. 2013).
