Poecilloptera constellaris Walker, 1858 prev. comb. of Pintalia constellaris (Walker, 1858) acc. to Fennah (1947); Pintalia quadrimaculata Fennah, 1945 syn. of Pintalia constellaris (Walker, 1858) acc. to Fennah (1947). Description. Coloration (specimen preserved in 70% ethanol). Body generally strong orange yellow (68), contrasting with regions in strong yellowish brown (74) of the carinae, deep orange yellow (69) on mesonotum, frons, and abdomen dorsally and brilliant orange yellow (67) on legs and abdomen ventrally. Tegmina Brilliant yellow (83) with a distal area hyaline, spot in deep yellow (85) with four hyaline points on the cubital, median and C5 cells. Body length. Male. 4.0– 4.3 mm (n=2). Head. Vertex (Fig. 39A, C): laterally wider, approx. 2.5 times wider (0.5) than medially long (0.2); apical compartment narrows and laterally larger, approx. 4.0 times wider (0.4) than medially long (0.1); apical transverse carina (0.413) slightly smaller than the subapical carina (0.437); angle formed by the caudal margin, concave irregular. Frons (Fig. 39B): 1.4 times longer (1.0) than wide (0.7), approx.1.7 times wider medially than apically (0.4); anterior region of the frons trapezoidal, wide and straight apically. Frontoclypeal suture large, very convex. Postclypeus (Fig. 39B): very carinated. Anteclypeus (Fig. 39B): with a distinct median carina apically, rounded close to the frons. Rostrum in ventral view reaching the middle of the abdomen. Thorax. Pronotum (Figs. 30A, C): submedian carinae weakly developed, evanescent behind the eyes; hind margin obtusely angled. Mesonotum (Fig. 30A): median carina well developed but evanescent distally; lateral carinae strongly developed. Tegmina (Forewings) (Fig. 39D): length 7.0 mm; dark yellow with a dark spot and four hyaline spots; dark spot between basal vein RP, hyaline spots over the veins MP, CuP, CuA1 and CuA2; r-m1 and m-cu1 occurs together before to the first MP fork; Cells C3 and C5, C4 narrow; small and simple tubercles in all veins; petiole in RP2.2+RP2.3 well developed; 12 apical cells; 7 subapical cells. Posterior legs. Hind tibia (Fig. 39E): approximately 2.3 mm; 6 apical spines; 4 lateral spines, the first being at the base of the tarsomere difficult to visualize; 1 st tarsomere (Fig. 39F): 7 apical teeth, the two outer teeth and the two middle teeth larger. 2 nd tarsomere (Fig. 39F): 7 apical teeth, the two outer ones being larger, and in the middle with approx. the same size; 3 platellae, one separated by apical teeth without platellae. Male terminalia. Pygofer (Figs. 40E–G): bilaterally symmetric. In lateral view, dorsocaudal margin with cone-shaped process tilted up laterally, rounded apically; in ventral view ventromedian process triangular, longer than wider. Anal tube (Figs. 40A–B, H; 41A–B): moderately short; in dorsal view slightly elevated medially with lateral margins slightly curved; in lateral view the lateral margins form one convex line. Genital styles (Figs. 40A–B, D; 41C–E): thin near to the base and distally approx. 3.5 times longer than wide with rounded distal margin; near of base with a small triangular process ventrally. Aedeagus (Figs. 40E–G; 41F–I): asymmetric tubular. Shaft of the aedeagus with five thin spines, four movable; in right lateral view with four spines, three large and curved spines (1 st, 2 nd, 3 rd) (a)(b)(c), occurs on the apex of the shaft, towards the base; spine (a) in S-shapped; spine (b) straight, biger the others; spine (C) in hook-shaped; 4 th spine (d) straight, inserted little above of the center on the aedeagal shaft towards the base; in left lateral view, 5 th spine small (e), not movable, occurs near the apex of the shaft towards to the flagellum. Flagellum with a spine-like process laterally. Diagnosis. Pintalia constellaris can be distinguished from other Pintalia species mainly by the spines apically on the aedeagal shaft towards the base of the shaft, with spine (b) being the largest of these. Distribution. BRA,AM, Ega(Tefé) (Type Locality);MG, Sete Lagoas municipality, Santa Barbara municipality, Iguatama municipality, Pains municipality; BOL, La Paz, Tumupasa (Fennah, 1945). Remarks. I was able to see images of the type deposited in the Natural History Museum, London (NHMUK) by Walker (1858). Despite the current state of conservation of the type, the specimen is identical to the specimen used in the (re)description, except for some small variations in the tegmina, such as the size of the spots and the spine (b) of the aedeagus, which is larger and curved in the specimen used by Walker (1858).
