description: <i>Erioloides acutidentis</i> Naskrecki and Cohn, n. sp. Figs. 22 F-G, 23C, 23H, 50C, Map15 Type locality: Costa Rica, Puntarenas Prov., Estac. Pittier; type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description.—</i> Very similar to the previous species; fastigium of vertex more pointed than in other species of the genus (Fig. 23 H). Male stridulatory file straight, 1.0 mm long, 103 μm wide, with 179 closely spaced and very wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part (Fig. 50 C); mirror elongately rectangular, distinctly longer than wide; secondary veinlet next to AA1 well developed, strongly divergent from AA1; stridulatory area of left wing devoid of secondary venation. Male 10th tergite with small, narrow incision on posterior margin (Fig. 22 F). Male cercus relatively slender, cylindrical, with small, spur-like dorsal spine; apex of cercus blunt (Fig. 22 F-G). Female cercus simple, elongately conical, distinctly curved. Titillators not clearly differentiated from phallic membrane, squamose (Fig. 23 C). Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate broadly triangular, with small, triangular incision at apex. Ovipositor relatively slender, with irregular lamella along midline of upper valvula; ratio ovipositor/hind femur 0.81. <i>Coloration</i>.— General coloration light green. Face pale green, mandibles brightly emerald green, labrum dark brown. Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green dorsally; purple ventrally; ovipositor light brown, with darker apex. <i>Measurements</i>.— Table 15. <i>Distribution</i>.— So far, this species is known from only a one locality in southern Puntarenas Prov. (Map 15). <i>Material examined.—</i> <b>COSTA RICA: Puntarenas Prov.</b>, Estac. Pittier, elev. 1670 m, 23 August - 13 September 1995 (coll. E. Navarro) - 1 female (allotype) (ANSP); same locality, 26 September - 5 October 1995 (coll. E. Navarro) - 1 male (holotype) (ANSP). <i>Etymology.—</i> The specific epithet refers to the sharp, spur-like spine on the male cercus. <i>Erioloides sikesi</i> Naskrecki and Cohn, n. sp. Figs. 22 I-H, 23D, 50B, Map 15 Type locality: Costa Rica, Puntarenas Prov., Res. Biol. Monteverde, Estac. La Casona; type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description (male, female unknown).—</i> Very similar to the previous species; fastigium of vertex more pointed than in other species of the genus. Male stridulatory file straight, 1.4 mm long, 146 μm wide, with 198 closely spaced and very wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part (Fig. 50 B); mirror nearly perfectly square; secondary veinlet next to AA1 present, parallel to AA1; stridulatory area of left wing devoid of secondary venation. Male 10th tergite with deep incision on posterior margin, resulting in two large, pointed lobes (note: Fig. 22 H shows the lobes from above, when the pointed ends of the lobes cannot be seen). Male cercus relatively slender, cylindrical, with small, blunt dorsal spine; apex of cercus blunt (Fig. 22I). Titillators flat, squamose, somewhat narrowed towards their apices (Fig. 23 D). Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate broadly triangular, with small, triangular incision at apex. <i>Coloration</i>.— General coloration light green. Face pale green, mandibles brightly emerald green, labrum yellow. Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green dorsally; purple ventrally. <i>Measurements</i>.— Table 15. <i>Distribution</i>.— This species is known only from its type locality (Map 15). <i>Material examined.—</i> <b>COSTA RICA: Puntarenas Prov.</b>, Estac. La Casona, Res. Biol. Monteverde, 1 - 30 April 1992 (coll. K. Flores) - 1 male (holotype) (ANSP). <i>Etymology.—</i> This species was named in honor of Derek S. Sikes, a fine coleopterist and good friend. <i>Erioloides latiscobinus</i> Naskrecki and Cohn, n. sp. Figs. 22 J-K, 23E, 49E, Map 15 Type locality: Costa Rica, Alajuela Prov., Sector Colonia Palmareña; type depository: Academy of Natural Sciences, Philadelphia – holotype male <i>Diagnostic description.—</i> Very similar to previous species. Male stridulatory file straight, 1.1 mm long, 145 μm wide, with 220 closely spaced and extremely wide, lamelliform teeth; teeth in proximal half of file thinner and more closely arranged than in distal part (Fig. 49 E); mirror approximately rectangular, distinctly longer than wide; secondary veinlet next to AA1 well developed, slightly divergent from AA1; stridulatory area of left wing devoid of secondary venation, distal margin of left mirror concave; secondary veinlet next to AA1 present, strongly divergent from AA1. Male 10th tergite with small, triangular apical incision (Fig. 22 J). Male cercus relatively slender, cylindrical, with thin, finger-like dorsal spine; apex of cercus somewhat constricted (Fig. 22 K). Female cercus simple, elongately conical, distinctly curved. Titillators flattened, squamose, apices multidentate, strongly divergent. Male subgenital plate with distinct ventral keel and deep triangular incision apically; female subgenital plate broadly triangular, with small, semicircular incision at apex. Ovipositor relatively slender, with file of pegs along midline of upper valvula; ratio ovipositor/hind femur 0.74-0.78. <i>Coloration</i>.— General coloration light green. Face pale green, mandibles brightly emerald green, labrum dark brown. Tegmina green, with contrastingly yellow venation. Legs green; abdomen light green dorsally; purple ventrally; ovipositor light brown, with darker apex. <i>Measurements</i>.— Table 15. <i>Distribution</i>.— This new species seems to be widely distributed in Costa Rica, with most records from low or mid elevation forest habitats (Map 15). <i>Material examined.—</i> <b>COSTA RICA: Alajuela Prov.</b>, Estac.
