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.
