Figs. 34 F-G, 35E, 35H, 35M, 51B, Map 18

Type locality: Costa Rica:, Guanacaste Prov., 3 km SE R. Naranjo; type depository: Academy of Natural Sciences, Philadelphia – holotype male

Diagnostic description.— The largest species of the genus; general characteristics as described above; wings in both sexes surpassing apices of hind femora by about fifth of their length. Fastigium of vertex twice as long as eye diameter, narrowly rounded apically, with distinct dorsal furrow dorsally; ventral keel of fastigium smooth ( Figs. 35 E, 35H). Male stridulatory file weakly curved, 1.4 mm long, 115 μm wide, with 310 closely spaced and relatively very wide teeth ( Fig. 51 B); stridulatory area on male without secondary venation; mirror square; secondary veinlet next to AA 1 present, divergent from AA 1. Ventral anterior spines of hind femora relatively short, as long as half of width of hind femur below knee ( Fig. 35 M).

Tenth tergite of male with two somewhat divergent, wide lobes; female 10th tergite with lobes somewhat narrower, pointed; male cercus straight, basal internal spine curved towards base, distinctly constricted apically ( Fig. 34 F); female cercus simple, elongately conical, somewhat curved. Male titillators needle-like, straight but slightly bent outwards apically ( Fig. 34 G). Ovipositor short, sickle-shaped, slightly longer than half of hind femur (ratio ovipositor/hind femur 0.66-0.70).

Coloration.— General coloration light green; face creamy white; fastigium reddish-brown; lower half of clypeus dark purple; metazona of pronotum in male with small, V-shaped, dark red spot, surrounded by thick, white margin; venation of tegmina and posterior edge of tegmina contrastingly yellow.

Measurements.— Table 27 .

Distribution.— This species is known only from a few widely scattered records in Cartago, Alajuela, and Guanacaste provinces ( Map 18 ).

Material examined.— COSTA RICA: Alajuela Prov., San Cristobal, elev. 600 - 620 m, 1 October - 30 November 1997 (coll. F.A. Quesada) - 1 male (paratype) ( INBio); Cartago Prov., Cachí, 6 February 1916 (coll. C.F. Lankester) - 1 female (paratype) ( ANSP); Guanacaste Prov., 3 km SE R. Naranjo, 1 November 1991 (coll. F.D. Parker) - 1 female (allotype) ( ANSP); same locality, 1 - 15 March 1992 (coll. F.D. Parker) - 1 male (holotype) ( ANSP); Estac. Las Pailas, P.N. Rincón de la Vieja, elev. 800 m, 6 - 7 June 1994 (coll. D. García) - 1 female (paratype) ( INBio); Estac. Pitilla, 9 km S Sta Cecilia, elev. 700 m, 15 May 1990 (coll. II curso Parataxon.) - 1 female (paratype) ( INBio).

Etymology.— This species is named in honor of Maylin Paniagua, a parataxonomist working with the project ALAS (Arthropoda of La Selva).
