Type locality: Costa Rica: Puntarenas Prov., Valle de Coto Brus, Las Cruces, Wilson Botanical Gardens; type depository: Academy of Natural Sciences, Philadelphia – holotype male

Diagnostic description.— General characteristics as described above. Tegmina surpassing apices of hind femora by only about 1/6 of their length. Male pronotum with metazona expanded, entirely covering stridulatory apparatus ( Fig. 38 View FIG. 38 C, 38E). Stridulatory file of male weakly curved, 1.8 mm long, with 137 (n=1) wide and thin teeth, maximum width of file 102 μm ( Fig. 50 View FIG. 50 G); teeth of file uniform in thickness, evenly spaced and smoothly narrowing towards proximal end. Male cercus weakly incurved, about twice as long as thick, with large apical spine ( Fig. 38 View FIG. 38 E); apices of titillators expanded and flattened, with several large teeth ( Fig. 33 View FIG. 33 G). Ovipositor distinctly curved upwards and widened midlength, slightly longer than half of hind femur (ratio ovipositor/hind femur 0.72-0.78).

Coloration.— General coloration chestnut brown, with wide, dark band extending across the top of the head, pronotum, and posterior edges of tegmina; tegmina with irregularly distributed, small, diffused darker spots; outer pagina of hind femur with distinct reticulate pattern. No green form is known for this species.

Measurements.— Table 25 View TABLE 25 .

Bioacoustics.— Males of S. scutellaris produce relatively high duty calls, consisting of paired chirps separated by about 1 second of silence (at 26°C) ( Figs. 58 View FIG. 58 E-F). Each chirp in a pair is produced by 6-7 wing strokes, and lasts 176-181 ms. Chirps in the pair are separated by 514-654 ms of silence (based on 5 recordings of 2 males). Males of this species alternate their calls if they can hear each other.

Distribution — Subria scutellaris is known only from southern portion of Puntarenas Province, near the bor- der with Panama ( Map 17 View MAPS 13 - 18 ). All specimens were collected at elevations of 700-1300 m.

Etymology.— The specific epithet reflects the somewhat enlarged, shield-like pronotum of the males of the new species.
