description: Agalliopsis mutabilis Gonçalves, Mejdalani & Coelho, sp. nov.
(Figs 3, 51–64, 73, 74)
Length. Male holotype 3.8 mm; male paratypes 3.6–3.7 mm; female paratype 4.0 mm.
Description (holotype). Head and thorax (color). Ground color brownish-yellow. Crown (Figs 51, 52) with five maculae as follows: dark brown pair approximately equidistant between eyes and median line, dark brown pair near inner margin of eyes, and inconspicuous brown one medially. Face (Fig. 52) with brown, incomplete inverted Y-shaped macula between ocelli; with pair of dark brown maculae adjacent to ocelli. Frons (Fig. 52) with several irregular brown maculae forming pair of lateral rows; clypeus brown on lower portion; genae with dark brown macula adjacent to antennal bases. Pronotum (Fig. 51) with four distinct maculae: one dark brown pair, elongate, adjacent to anterior margin and one brown pair, round, on median region. Mesoscutum (Fig. 51) with pair of lateral, triangular dark brown maculae; mesoscutellum with irregular brown macula at median region. Forewings with conspicuous, elongate brown macula on costal anterior area, veins on basal half partially covered by brown marks.
Male genitalia. Pygofer (Fig. 53), in lateral view, with posterior margin with scattered setae (Fig. 54), bearing process with bifurcate apex directed inward (Fig. 55). Subgenital plates (Fig. 56), in ventral view, elongate, subtriangular, fused to valve and to each other along basal half, narrowing gradually towards apical 1/4; apex broad; in lateral view (Fig. 53), extending posteriorly slightly beyond pygofer apex. Styles (Fig. 57), in dorsal view, well developed, outer fork small and rounded, inner fork larger with basal portion strongly curved and apical portion digitiform. Connective (Fig. 64), in lateral view, linear, fused to aedeagus; in dorsal view, with form of short linear bar. Aedeagus (Figs 58, 59), in lateral view, with basal region well developed, subtriangular; shaft directed ventrally and then dorsally beyond basal region, posterior half with ventral and dorsal keels. Anal tube (Fig. 53) with segment X bearing pair of elongate processes, directed caudoventrally, with hook-shaped apex (Fig. 60); segment XI with spiniform projection on inferior margin.
Female (color). Abdominal sternite VII (Fig. 61) yellow; laterotergites of segment VIII yellow; pygofer (Fig. 61), in ventral view, with outer lateral margins brown; gonoplacs brown. Other features similar to those of the male holotype.
Female genitalia. Abdominal sternite VII (Fig. 61), in ventral view, with oblique posterolateral margins and small emargination on apical portion. First valvulae, in lateral view, dorsally curved from base; dorsolateral surface with oblique rows of scale-like processes on distal 1/2 of shaft; ventroapical region with scale-like processes; apex acute. Second valvulae (Fig. 73), in lateral view, dorsally curved from base, with broadest point at apical 1/4; dorsal prominence inconspicuous; small teeth (Fig. 74) along apical 1/3 of dorsal margin; denticles may be present on teeth; ventroapical region with tiny teeth; apex of shaft subacute. Gonoplacs as in A. dutrai sp. nov.
Intraspecific variation (male paratypes). Crown (Figs 62, 63) without brown macula on median region; face (Fig. 63) with Y-shaped macula more conspicuous than that of the holotype. Pronotum, mesonotum (Fig. 62), and forewings may present larger brown areas, being distinctly darker than in the holotype. Aedeagus (Fig. 64) without ventral keel.
Etymology. The species epithet, mutabilis, refers to the intraspecific variations observed in the color pattern and aedeagus shape.
Type material. Holotype: male, Brazil, “ Viçosa, MG [Minas Gerais State], Brasil \ Data 13/I/1987 \ P. S. Fiuza F. [Ferreira]” (DZRJ). Three paratypes with same data as holotype, except: one female “ 29/IX/1992 ” (DZRJ), one male “ 27/I/1982 ” (UFV), one male “ 05/III/1987 ” (MNRJ).
