Head: Frons approximately four times as long as broad (Fig. 5C); head projection beyond eyes without angulation in profile (Figs 1G, H, 5A, B, D); lateral carina of frons parallel in ventral view (Fig. 5C); vertex trapezoidal in dorsal view (Fig. 5E); epistomal suture medially triangular (Fig. 5C); clypeus approximately four times as long as broad (Fig. 5C); median carina absent (Figs 5C, D). Thorax: pronotum with anterior margin truncate (Fig. 5E); mesonotum with lateral carina parallel (Fig. 5E). Forewing: ScP+R vein long, finishing at level of clavus apex; RA vein slightly curved anteriorly at apex; RP vein arising before ScP vein; RP vein with four cells (C1, C1’, C1b, C1b’); MP 1+2 vein forking distal to ir cross-vein (Fig. 5F). Male terminalia (Figs 6A–E, 7A–E): Pygofer symmetrical, subrectangular, narrowest dorsally, with digitiform projection on posterodorsal margin in lateral view (Figs 6A–C); projection digitiform, elongated and robust, extending beyond middle of anal tube, apex rounded in lateral view (Figs 6A, B); medioventral process small, slightly produced in lateral view, subtriangular, with apex forming obtuse angle at apex in ventral view (Fig. 6C). Gonostyli symmetrical, spatulate, apex rounded in lateral view, subequal in length to anal tube (Figs 6A, D); dorsal margin with two processes near apex and a row of setae up to base of first process. P1: first process bifid, with lobes of unequal size, one sclerotised spiniform lobe and one robust lobe with rounded apex; P2: subtriangular process bearing a few apical setae (Figs 6D, E); ventral margin sinuous, with a single sclerotised subtriangular process located at mid-length, apex of process curved ventrally (Figs 6D, E). Phallic complex symmetrical (Figs 7A, B): periandrium slightly sclerotized, without spiniform projections. Aedeagus with the following process: one long, laterally compressed process, widened in basal two-third and slender in apical third in lateral view, narrow and convergent in dorsal view (S1); one bifid process with unequal spines (S2): one short, slender and curved spine (S2a); one long, slender, sinuous spine (S2b); one falciform spine, curved ventrally in apical half (S3); and one shorter, slender, straight apical spine, inserted at apex (S4). Anal tube (segment X) robust and expanded distally; dorsal margin almost straight; ventral margin sinuous with a shallow apical reentrance occupying less than 1/4 apical of total length of anal tube, forming two lobes in ventral view (Fig. 7E); lobes almost straight, robust, with rounded apex in dorsal view (Figs 7C–E). Paraproct subquadrangular, with truncate apex, almost subequal in length to lobes of anal tube in dorsal view (Fig. 7D). Female similar to male (Fig. 5B). Female terminalia (Figs 8A–E, 9A–D). Pregenital sternite (Sternite VII) semicircular, with subrounded apex of medioventral process in ventral view (Fig. 8B). Sternite VIII subtriangular, apex rounded in lateral view (Fig. 8A). Gonapophysis VIII (first valvula) with one long, slender projection on dorsoapical margin, bearing elevated irregular teeth in lateral view, forming a concavity in dorsal view; a shorter, upwardly curved lateroapical projection with toothed dorsal margin in lateral view (Fig. 8D). Bursa copulatrix bifid, with apically filamentous lobes narrowing toward apex, apexes rounded, covered by small spiniform projections on apical half in lateral view (Fig. 8D). Gonapophysis IX (second valvula) robust, basally wider, bifid at apical ¾; lobes with pointed and bifid apexes, straight posteriorly; ventral region of lobes with fine, short setae on apical ¾; basal half of gonapophysis IX with ventral spiniform projections (Fig. 8E); basal plate of gonapophysis IX 2.8 times longer than wide; anterior margin with median projection; apex of projection truncate (Fig. 8E). Gonoplac (third valvula) subrectangular, apex truncate, with smooth indentation, and bearing numerous setae apically in lateral view (Fig. 9A). Anal tube (segment X) short, subquadrate in dorsal view (Fig. 9C); ventral margin with reentrant area bearing an elongate, slender digitiform lobe with three long apical spiniform setae, each approximately half length of lobe (Figs 9B, D). Paraproct, subcircular, with prominent apical region in dorsal view (Fig. 9C). Variations. In some female specimens, the medioventral process of sternite VII presents an indentation at the apex of the posterior margin, in ventral view (Fig. 8C). Furthermore, the number of setae at the apex of the anal tube lobe varies from three to four. Etymology. The species is named in honor of PhD Daniela Maeda Takiya, from the Federal University of Rio de Janeiro (UFRJ), in recognition of her significant contributions to the knowledge of the Brazilian hemipteran fauna.

Persis (Anapersis) takiyae sp. nov. is most similar to P. (A.) ferox in having a small medioventral process of the pygofer, and black spots on the pronotum. However, P. (A.) takiyae sp. nov. differs from the latter and all other species of the genus (except P. (A.) pallidovenosa) by the absence of an obtuse angle formed between the vertex and frons in lateral view. Although P. (A.) takiyae sp. nov. and P. (A.) pallidovenosa share a rounded head shape in lateral view, in P. (A.) pallidovenosa the pronotum lacks spots and the wings are pale yellow with white veins, contrasting with the coloration observed in P. (A.) takiyae sp. nov..
