(Figs 1–5)
Diagnosis. Crown (Fig. 3A, C) with four orange stripes, three longitudinal and one transverse forming E-shaped macula. Forewing (Fig. 3A–D) yellow with a brown stripe along the entire anal margin and appendix. Male pygofer (Fig. 1F) dorsal margin with an elongated, narrow and acute process, contiguous to the margin, slightly surpassing pygofer apex; ventral margin with a small dentiform apical process. Subgenital plates, in lateral view (Fig. 1E, H) surpassing the pygofer apex, narrow at base and widened on apical half; in ventral view (Fig. 1G) plates fused together along their entire length, except apically. Connective (Fig. 1I) Y-shaped.Aedeagus (Fig. 1K) in lateral view with atrium broad bearing an acute, slightly recurved ventral process nearly same size and shape as shaft, fused basally to shaft, expanded subapically in posterior view (Fig. 1L); shaft tubular, elongated and narrow, with apex subacute. Female sternite VII (Fig. 2A, C) wider than long; posterior margin with median third deeply and roundly excavated.
Measurements. Holotype male: total length 5.7. Paratypes: males (n = 13), 5.5–5.9 mm; females (n = 34), 6.0– 6.5 mm.
Coloration. Green, in life (Fig. 3E), pale yellow, preserved (Fig 3A–D). Crown (Fig. 3A) with four orange stripes, three longitudinal and one transverse forming E-shaped macula, longitudinal strips extending to mesonotum. Forewing (Fig. 3A–D) yellow with a brown stripe along the entire anal margin and appendix.

Metatarsomere I longer than combined length of two distal tarsomeres; plantar surface with two rows of setae, external row with longer and robust setae than inner row; pecten with 4–5 platellae. Metatarsomere II pecten with 3 platellae.
Male terminalia. Pygofer, in lateral view (Fig. 1E, F), subtriangular, wide at the base and progressively narrowing towards the apex; dorsal and ventral margins strongly sclerotized; dorsal margin with an elongated, narrow and acute process, contiguous to the margin, slightly surpassing pygofer apex; ventral margin broadly rounded on basal half, apical portion with a small dentiform process; apex subtruncate.

Subgenital plates, in lateral view (Fig. 1E, H) surpassing the pygofer apex, approximately 2.3 times longer than maximum height; narrow at base and widened on apical half; dorsal margin excavated on basal half and rounded on apical half, with a tuft of small setae; apex rounded; in ventral view (Fig. 1G) oval, plates fused together along their entire length, except apically; anterior margin deeply excavated; lateral margins rounded and convergent anteriorly and posteriorly; apex of each plate rounded. Connective (Fig. 1I) Y-shaped, arms slightly longer than stem; approximately two-thirds length of style; slender dorsal keel present and projected anteriorly between arms. Style (Fig. 1E, I, J) with apophysis moderately stout, slightly expanded apically; preapical lobe reduced and rounded, with some elongated setae; apex curved ventrally, hook-shaped.

Etymology. The species epithet is a noun in apposition based on the Portuguese common name of the tree on which the new species was collected, “Aroeira-Pimenteira.”

Remarks. Coelidiana aroeira sp. nov. resembles Coelidiana brasiliensis and Coelidiana diminuta due to the presence of a single ventral process on the aedeagus but the former differs in having the ventral process of the aedeagus basally fused to the shaft (Fig. 1K).
