Etymology. The new species is dedicated to the mother of the senior author, Aurinda Penalva. Male holotype (Fig. 1). Body dark brown, with wide green spots on abdominal segments 3���7 in dorsal view. Head. Labium pale brown, with lateral lobe dark brown. Labrum brown, surrounded by an irregular light brown to ochraceous border, a small brownish depression fused at base of labrum. Genae and anteclypeus brownish or slightly greenish; occiput dark brown, postclypeus brown. Frons and vertex dark metallic violet the latter with two small tubercles. Eyes in life blue, antennae light brown; rear of head ochraceous, dark brown basally. Thorax. Prothorax dark brown, anterior lobe narrowly pale laterally, median lobe ochraceous, posterior lobe dark brown with distal border pale and bare. Pterothorax including antealar crest metallic blue at maturity, and covered with light brown hair. Sides of pterothorax metallic green behind mesopleural suture becoming ochraceous. Legs long and robust. Trochanter and bases of femora pale brown, remainder of legs dark brown. Profemur 1 with 11 spines; outer angle of mesofemur (Fig. 6a) with four stout spines, followed by a row of short spines, metafemur (Figs. 6b, c) with six stout spines, followed by a row of short spines, claws with well-developed inferior tooth. Wings. (Fig. 1) As described for genus. Abdomen. (Fig. 13) Triquetral, slightly broader on segments 5���7 in dorsal view; segments 2���3 slightly constricted and transversely carinate, the lateral carina or keel on segment two bent forward in a rounded curve (Fig. 4); anterior lamina small, rectangular, about 1.5 longer than wide, lower than hamule. Genital lobes shallowly separated; hamule in ventral view (Fig. 10b) narrower than in species of Tauriphila and in lateral view (Fig. 10a) shorter than genital lobe. Cercus (Figs. 10c, d) of male in lateral view with dorsal margin slightly convex, nearly straight distally, not as long as segments 9 and 10 combined. Abdominal coloration dark brown, with wide green spots on segments 3���7 in dorsal view. Vesica spermalis (penis) as in Figs. 11a���b, well developed, apex of distal segment with two long lateral lobes, with spines Measurements (mm). Total length (incl. app.) 44.0, ��� FW 35.0, ��� HW 33.0, ��� cerci 2.0, ��� epiproct 1.8, ��� profemur: 0.5. ��� mesofemur: 0.7, ��� metafemur: 0.5, protibia: 0.6, ��� mesotibia: 0.7, ��� metatibia: 0.8, ��� abdomen 30.0. Female allotype. Similar to male with the following differences: frons ochraceous, metallic violet less intense; vertex dark brown, ochraceous apically, occiput pale; outer angle of mesofemur with seven stout spines, followed by series of four small spines (Fig. 8a); metafemur with nine stout spines (Fig. 8b). Venation similar to male but with following differences: FW with 12 anx and 7���8 pnx; HW with 7 anx and 8 pnx (9 in left HW). Abdomen as in male with following differences: pale coloration on segments 3���7 ill-defined in dorsal view. Epiproct small, vulvar lamina as shown in Fig. 12. Measurements (mm). Total length (incl. app.) 43.0, ��� FW 32.0, ��� HW 31.2, ��� mesofemur: 0.5. ��� mesofemur: 0.7, ��� metafemur: 0.8, protibia: 0.6, ��� mesotibia: 0.7, ��� metatibia: 0.8, ��� abdomen 30.0. Variation (n = 15). FW: with 12 anx and 8���9 pnx in three specimens. HW with 8 anx and 9���10 pnx. Profemur with 11 spines; outer angle of mesofemur with three stout spines, followed by row of short spines, metafemur with five to seven stout spines followed by row of short spines.
