Copiphora brevicauda costaricensis sp. n. Common name: Costa Rican spear bearer Figs. 8 F-I, 42F, 55F-G, Map 5 Type locality: Costa Rica, Heredia Prov., La Selva Biological Station; type depository: Academy of Natural Sciences, Philadelphia ��� holotype male Diagnostic description.��� Fastigium of vertex forming relatively small horn, with well developed ventral keel, keel often slightly expanded subapically (Fig. 8 F). Stridulatory file 2.7 mm long, with 154 teeth, teeth in distal half of file distinctly thicker and less densely distributed (Fig. 42 F). Ovipositor relatively short compared to other members of the genus, ratio ovipositor/hind femur 1.9-2.1 (Fig. 8 H). Tegmina never mottled with brown dots. Measurements.��� Table 4. Bioacoustics.��� C. brevicauda costaricensis produce low duty, relatively high Q calls, consisting of irregular series of long chirps. Individual series of chirps last about 2.6 s (at 25��C) and are produced after intervals of several minutes of silence. Each series has 5-7 chirps, with each chirp lasting 185.3-269.1 ms (n=7), and consisting of 8-13 individual pulses. Most energy of the call is allocated between 9.2 and 11.8 kHz. Distribution.��� This subspecies seems to be endemic to Costa Rica. Material examined.��� COSTA RICA: Cartago Prov., Chitar��a, elev. 500 m, 9 June 1929 (coll. M.
