Mus. 2: 310; type locality: Venezuela, type depository: Museum of Natural History, London. Diagnostic description.��� General characteristics as described above. Wings fully developed, well surpassing apices of hind femora or shortened, not reaching apex of abdomen. Stridulatory file of male 3.2 mm long, with 113 lamelliform teeth, maximum width of file 0.27 mm (Figs. 46 A-B); teeth of file uniform in thickness, evenly spaced and smoothly narrowing towards proximal end. Mirror of stridulatory apparatus somewhat longer than wide, with all margins convex. Fastigium of vertex about 4 times as wide as scapus, continuous with fastigium of frons; apex of fastigium of frons shallowly notched (Figs. 14 F-H). Ovipositor somewhat longer than hind femur (ratio (all measurements are lengths in mm: range, mean��SD) ovipositor/hind femur 1.20-1.29), weakly downcurved. Coloration.��� Body coloration brown or olive green; dorsum of pronotum darker, with two dark brown stripes on edges; tegmina with numerous dark speckles. Measurements.��� Table 9. Bioacoustics.��� Belwood and Morris (1987) presented a spectrogram the call of B. capitatus (populations from Barro Colorado Island, Panama). The call is continuous, with an average call repetition rate of 450/min, and wide frequency range (approx. 7-40 kHz). Distribution.��� The geographic distribution of this species stretches from Guatemala through Costa Rica and Panama, to Venezuela and Bahia, Brazil. In Costa Rica this species is apparently uncommon, and is known only from one individual collected on the Osa Peninsula (Map 9). Material examined.��� COSTA RICA: Puntarenas Prov., Bosque Esquinas, Pen��nsula de Osa, elev. 200 m, 1 - 30 May 1994 (coll. J. Quesada) - 1 female (INBio). Other material.��� Panama, French Guyana, and Venezuela.
