( Figs. 8–9 View FIGURE 8 View FIGURE 9 )

Type material. Holotype ♂ ( Fig. 8A View FIGURE 8 ) “ Costa Rica, Puntarenas / Corcovado National Park / La Sirena Biological Station // N08º28’46” W083º35’25” / 0 m / 10–13.ii.2011 / light trap / DM Takiya ” ( MUCR). GoogleMaps

Type locality. La Sirena Biological Station , Puntarenas, Costa Rica.

Etymology. The species is named for Dra. Daniela M. Takiya, a leafhopper specialist with an interest in cicadas, who collected the type specimen.

Description. Body orange marked with castaneous and tawny, covered by silver setae.

Head ( Fig. 8 View FIGURE 8 A–C). Head orange, castaneous mark along anterior arms or epicranial suture, mark extending posteriorly onto anterior vertex between lateral ocellus and supra-antennal plate, tawny between eye and lateral ocellus. Eyes dark castaneous, ocelli red. Head covered with short silver setae, longer and denser posterior to eye. Ventral head light tawny with silver setae. Postclypeus a darker shade of orange, with nine light orange transverse grooves and inconspicuous central sulcus. Anteclypeus light orange, carina darker, covered with silver setae. Scape, pedicel and antennal flagella tawny. Mentum light orange, labium light orange with slightly castaneous apex. Labium long, reaching abdominal sternite II.

Thorax ( Fig. 8A, B, D View FIGURE 8 ). Pronotum and pronotal collar orange covered by silver setae, piceous setae forming spots on either side of anterior midline, posterior to medial terminus of paramedian fissures and on either side of pronotal collar midline. Castaneous mark in anterior paramedian fissure and all of lateral fissure, pronotal collar with castaneous region on either side of dorsal midline. Lateral angle of pronotal collar projected laterally, wider than mesonotum, lateral pronotal collar margin convex. Mesonotum orange covered by silver setae, submedian and lateral sigilla slightly mottled withpiceous. Wing groove tawny parallel to mesonotum lateral margin. Cruciform elevation light orange, midline and lateral projections darker, lateral surface flat, posterior arms short, transversely oriented, not covering entire abdominal tergite 1.

Operculum ( Fig. 8E View FIGURE 8 ). Male operculum orange, covered by silver setae, sub-triangular, lateral and posterior margins convex becoming slightly concave forming posterolateral extension, operculum not covering timbal or tympanal cavities completely. Internal angles of operculum nearly touching each other medially. Meracanthus tawny with castaneous spot on base, an elongated triangle curving towards midline, not reaching half the length of operculum.

Wings ( Fig. 8A View FIGURE 8 ). Wings hyaline.Veins orange, costal and radius + subcostal veins castaneous distal to basal cell. Forewings of holotype with multiple mutations: left forewing with seven apical cells, a new cell between ulnar cell 1 and apical cell 2, and additional cell between ulnar cell 3 and apical cell 5; median vein incomplete in middle; right forewing with six apical cells, a new cell between ulnar cell 2 and apical cell 3, medial cell reaching ambient vein. Basal cell clouded, about twice as long as broad, apical cell 1 almost as wide as apical cell 2. Hindwings with six apical cells. Jugal fold long, anal vein 2 extending half the length of anal cell 2 with curved distal terminus, white in cells at hindwing base, white extends along proximal three quarters of posterior side of cubitus posterior, both sides of anal vein 2, along anal vein 3 in anal cell 2 and all of anal cell 3.

Legs ( Fig. 8C, D View FIGURE 8 ). Coxae light orange with castaneous marks anteriorly and laterally, trochanters light orange with castaneous marks ventrally, and femora light orange striped with castaneous. Fore femora with castaneous fasciae and three spines, the primary spine horizontal in relation to femur, secondary spine largest and slightly inclined, and very small tertiary spine. Tibia orange covered by silver setae. Tarsi tawny. Pretarsal claws castaneous with piceous tips.

Abdomen ( Fig. 8A, F, G View FIGURE 8 ). Abdomen subcylindrical, segment 2 widest, posterior segments narrower than preceding segment to posterior terminus. Tergites light orange marked with castaneous, tergites 1 and 2 castaneous dorsally, tergites 3–7 castaneous posteriorly on dorsolateral tergites, amount of castaneous increasing in posterior segments, covered by white setae, very dense dorsolaterally. Timbal cover flat, medial margin convex, dorsolateral margin recurved, curving to acutely angled apex almost reaching lateral metascutellar plate, ventrolateral margin convex almost meeting the lateral margin of operculum. Sternite I light orange, swollen medially, median projection of anterior margin tightly arched. Sternite VII sub-rectangular longer than sternites II–VI, lateral margin concave becoming convex towards posterior, posterior margin straight. Sternite VIII ovoid with white setae at apex.

Genitalia ( Fig. 9 View FIGURE 9 ). Pygofer subcylindrical; pygofer basal lobe adpressed to lateral margin of pygofer, triangular apex. Uncus longer than basal lobe in lateral view; uncal dorsal crest divided medially, recurved distally to project posteriorly; lateral branch of uncus with distal margin strongly arched, lateral surfaces indented under arch, apex directed anteriorly; ventral apophyses formed from lateral branches of uncus fused. Theca tubular with a ventral fissure through which the vesica is extended and forms two lateral flaps with ventral rows of sclerotized cornuti. Vesica long, slender, with sclerotized apical region and cornuti. Spine of vesica in middle. Female is unknown.
