description: Agalliopsis chaelata Gonçalves, Mejdalani & Coelho, sp. nov.
(Figs 20–30, 67, 68)
Length. Male holotype 3.7 mm; male paratypes 3.6–3.9 mm; female paratypes 4.0–4.1 mm.
Description (holotype). Head and thorax (color). Ground color yellow. Crown (Figs 20, 21) with seven dark brown marks as follows: one pair close to inner margin of eyes, two pairs about equidistant between eyes and median line (one at anterior and another at posterior margin), and one at median line. Face (Fig. 21) with brown inverted Y-shaped macula between ocelli, contiguous with median coronal macula (arms of “Y” not fused medially); tiny dark brown maculae adjacent to ocelli; pair of dark brown maculae close to inner margins of eyes. Frons (Fig. 21) with brown irregular maculae forming pair of lateral rows; genae with pair of dark brown maculae adjacent to antennal bases; apex of rostrum dark brown. Pronotum (Fig. 20) with dark brown line contiguous to coronal median macula, narrowing towards posterior margin of disc, anterior margin with inconspicuous brown areas, lateral margins with pair of brown maculae. Mesoscutum (Fig. 20) with pair of laterobasal dark brown maculae and pair of small round dark brown marks at central portion. Forewings with ground color pale yellow. Mesothorax with large dark brown area lateroventrally.
Male genitalia. Pygofer (Fig. 22), in lateral view, short, posterior margin rounded and with chelate process (Fig 23) directed inward. Subgenital plates (Fig. 24), in ventral view, elongate, triangular, fused to each other at basal portion, not fused to valve; in lateral view (Figs 22, 25), extending beyond pygofer, with longer setae on superior portion. Styles (Fig. 26), in dorsal view, large, outer fork small and rounded with few setae on preapical region, inner fork much more developed, narrowing towards rounded apex; dorsal style surface with concavity for articulation with connective. Connective (Fig. 28), in lateral view, linear, not fused to aedeagus; Y-shaped in dorsal view (Fig. 27). Aedeagus (Fig. 28), in lateral view, broad basally, with slender and sinuous shaft curved above base and directed caudally; with complex structure at apical region expanded dorsally, ventrally and posteriorly, dorsal rami from this structure connected to anal tube; apical region of shaft (Fig. 29) divided into two ends with bifurcate and acute apices. Anal tube (Fig. 22), in caudal view, with segment XI bearing pair of delicate, ventral elongate processes.
Female (color). Abdominal sternite VII (Fig. 30) yellow; laterotergites of segment VIII yellow with pair of tiny brown maculae on inner basal region; pygofer (Fig. 30), in ventral view, yellow; gonoplacs pale brown. Other features similar to those of the male holotype.
Female genitalia. Abdominal sternite VII (Fig. 30), in ventral view, moderately produced posteriorly; posterior margin convex, subtruncate at median portion. First valvulae, in lateral view, slightly dorsally curved from base; dorsolateral surface with oblique rows of scale-like processes on posterior 2/3 of shaft; ventroapical region with scale-like processes; apex subacute. Second valvulae (Fig. 67), in lateral view, slightly dorsally curved from base, with broadest area at apical 1/4; dorsal hyaline area present; dorsal prominence slight, inconspicuous; small teeth (Fig. 68) along apical half of dorsal margin, increasing in size slightly towards apex, without denticles; ventroapical region with tiny teeth; shaft apex rounded. Gonoplacs as in A. dutrai sp. nov.
Etymology. The species epithet, chaelata, refers to the peculiar chelate processes of the pygofer and aedeagus, which are diagnostic of the new taxon.
Type material. Holotype: male, Brazil, “ Viçosa, MG [Minas Gerais State], Brasil \ Data 2/X/1987 \ P. S. Fiuza F. [Ferreira]” (DZRJ).
