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.

Agalliopsis
sp., female. (48) Crown, pronotum and mesonotum, dorsal view; (49) face; (50) apical portion of abdomen, ventral view.
Etymology
. The species epithet,
mutabilis
, refers to the intraspecific variations observed in the color pattern and aedeagus shape.
