Figs. 32 A-D, 37C, 50F, Map 16 Type locality: Costa Rica: Heredia Prov., La Selva Biological Station; type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description.—</i> Body small, slender, with wings in both sexes extending beyond apices of hind femora by about half of their length (Fig. 37 C). Fastigium of vertex conical, with well developed ventral keel, as long as 1.5 eye diameter. Prosternum unarmed. Male stridulatory file weakly sinusoidal, 1.2 mm long, 76 μm wide, with 146 closely spaced and relatively narrow teeth (Fig. 50 F); stridulatory area on male wings strongly projecting, approximately triangular in shape; mirror triangular; secondary veinlet next to AA1 present, parallel; stridulatory area of left wing devoid of secondary venation. Tenth tergite in both sexes with two, somewhat converging, long and narrow, apically rounded lobes; male cercus about twice as long as thick, with thin, finger-like, subapical spine (Fig. 32 A); female cercus simple, elongately conical, somewhat curved. Male titillators in the form of a tuft of thin, cuticular threads, their basal parts hidden in sheath of phallic membrane (Figs. 32 C- D). Male subgenital plate with small apical incision and long styli; female subgenital plate approximately triangular, with minute, triangular lobe on its hind margin. Ovipositor long, saber-shaped, distinctly longer than half of hind femur (ratio ovipositor/hind femur 0.77-0.93) (Fig. 32 B). <i>Coloration</i>.— General coloration pale green (Fig. 37 C); clypeus and mandibles purple; pronotum in both sexes with two thin, yellow stripes on dorsal edges of pronotum; posterior edge of metazona in male without additional markings; tegmina with irregularly distributed, numerous small, black dots. <i>Measurements</i>.— Table 23. <i>Distribution</i>.— <i>E. penicillus</i> is known only from the northeastern Atlantic portion of Costa Rica (Map 16). <i>Material examined.—</i> <b>COSTA RICA: Heredia Prov.</b>, Finca Naranjo Valenciana, 2 km S Pueblo Nuevo, Sarapiquí, elev. 90 m, 9 - 30 September 1992 (coll.
