Description of holotype, ♀. Body length: 2.16 mm. Fore wing length: 1.96 mm.
Color. Black. Head with apical gena and mandibles light brown, palps yellowish brown. Wings hyaline with two fuscous bands poorly defined near the middle. Legs light brown except for hind coxae dorsally black. Metasoma brown.
Head. Length of head in dorsal view 0.52× longer than wide; temples rounded just behind eyes, weakly narrowing posteriorly. Antennae 1.0.× the body length; scape 2.5× longer than wide; flagellomeres 1–5 slender, 6–17 with an expansion apical-ventrally. Eye height 2.9× the malar space length. Sculpturing mostly rugose except gena and temples smooth to sparsely punctate; face with a short longitudinal carina just below antennal socket. Malar suture present.
Mesosoma. Mesonotum areolate-rugulose. Notauli absent. Propleuron rugose. Pronotum strongly rugose without distinct groove. Scutellar sulcus with 6 divisions. Scutellum superficially areolate-rugulose. Mesoscutellar trough and metanotum rugose. Mesopleuron mostly smooth and polished with rugose area anteriorly. Sternaulus large and widely costate. Metapleuron strongly rugose. Propodeum mostly smooth; anterior aspect with two weak submedian and two distinct lateral carinae; posterior aspect with two median and two lateral carinae; transverse carina high and complete, not interrupted medially.
Wings. Fore wing vein r present, about 0.5× stigma height; vein R1 0.6 x the stigma length; stigma about 3.5× longer than high.
Legs. Hind legs with inner tibial spur 0.36× longer than tibia; hind tibia 4.4× longer than its maximum width. Mostly punctate; hind coxa rugose dorsally.
Metasoma. Entirely smooth.
Variation. Body length: 1.8–2.3 mm. Fore wing length: 1.9–2.0 mm. Face with median carina varying from a small indistinct carina to a drop-shaped carina. There is some degree of variation in deepness of dark coloration
Male. Essentially as in female except for antennae with slender flagellomeres, without ventral expansions.Variation. Body length: 1.8–2.0 mm. Fore wing length: 1.9–2.0 mm.
Diagnosis. Adelius monteiroi sp. n. is distinct from others in having the combination of a mostly black coloration, wings distinctly banded, and the presence of vein r on fore wing. It differs from other mainly dark species, with rugose hind coxa, and fore wing vein r present (i.e. A. boliviensis sp. n., A. excelsus sp. n., A. ecuadoriensis sp. n. and A. morretesiensis sp. n.), by its banded wings and mostly rugose head. The only other species with vein r present and having banded wings is Adelius sancticaroli sp. n., which is a much lighter (mainly yellow), and is a much smoother species than A. monteiroi .
Distribution. Known only from the type locality in Itatiaia National Park, at high altitudes around 2,200 meters, where the vegetation cover is mainly high-altitude grasslands.
Etymology. The species in named after our colleague Ricardo Monteiro, in appreciation for his valuable contributions to the study of the Brazilian insects.
Type material. Holotype ♂ ( DCBU 31303 View Materials ): “ Morretes , PR, Brasil, Parque Est. do Pau Oco, 10–13.IV.2002 —Malaise, Ponto 1—Trilha, M.T. Tavares e eq. col.”.
Description of holotype, ♂. Body length: 1.5 mm; fore wing length: 1.3 mm
Color. Head brown with black vertex; cape, pedicels and flagellomeres 1 –5 yellowish; tips of mandibles dark brown; palpi white. Mesosoma black except for propleuron and pronotum brown. Wings hyaline, stigma and venation brown. Fore and middle legs light yellow. Hind legs with coxae light brown, trochanter and trochantellus yellowish, remainder brown. Metasoma dark brown, except for anterior T1 black.
Head. Length of head in dorsal view 0.5× width. Antennae as long as the body; scape 2.5× longer than wide; all flagellomeres longer than wide. Eye height 2.4× malar space. Sculpturing mostly strongly areolate-rugulose, face transversely rugose-striate. Malar suture present.
Mesosoma. Mesoscutum areolate-rugulose. Notauli absent. Propleuron punctate. Pronotum smooth with rugose groove. Scutellar sulcus with 8 divisions, scutellum areolate-rugulose to punctate. Mesopleuron mostly punctate, smooth and polished dorsally; sternaulus rugose-costate. Mesoscutellar trough and metanotum rugose. Metapleuron strigate. Propodeum with well-defined areola extending over its entire length; anterior aspect rugose and posterior aspect smooth; with complete transverse carina not interrupted medially, and lateral carinae; all carinae well defined.
Wings. Fore wing vein r absent; vein R1 0.7× stigma width; stigma 3.0× longer than high.
Legs. Hind tibial spurs about 0.27× hind tibia; hind tibia 4.2× longer than its maximum width. All coxae smooth and polished, remainder legs mostly punctate.
Metasoma. Entirely smooth.
Diagnosis. The mostly black body with head mainly brown, wings hyaline, fore wing vein r absent and vein R1 relatively long, and hind coxa being smooth and polished are distinctive. Adelius morretesiensis sp. n. is similar in most of diagnostic characters to A. bolivariensis sp. n., differing from it by the black mesosoma, which is yellowish brown in A. bolivariensis (see further comments on these two species at the diagnosis section for A. morretesiensis ).
Distribution. Found in the Brazilian southern states of Paraná.
Etymology. This species is named after the city where the holotype was collected.
