Gampsocleis sedakovii obscura, Gampsocelis sedakovii obscura Green Morph, Gampsocleis sedakovii oscura Brown Morph
Acoustic characteristics. The mean 6 SE of the various acoustic character- istics determined from recordings of the green and brown morphs of G. s. obscura are listed in Table 2. The calling song of the individuals was continuous, consisting of series of single pulses as shown in Fig. 2. All acoustic data were found to be distributed normally by the Shapiro–Wilk test; therefore, a t test was conducted to determine statistical differences between the green and brown morphs for each of the acoustic characteristics of the recorded songs. Based on these comparisons, the pulse duration, pulse interval, and dominant frequency differed significantly (P <0.001) between the two color forms (Table 2). The highest frequency and lowest frequency, however, did not differ (Table 2). [1]

Morphological traits. The teeth of the stridulatory files of both morphs were claviform, with the teeth in the middle section being wider than those located at both ends of the file. Neither the width (t 1⁄4 0.068; df 1⁄4 9; P 1⁄4 0.963) nor the number (t 1⁄4 1.269; df 1⁄4 9; P 1⁄4 0.339) of teeth on the stridulatory file differed significantly between the two morphs (Table 3). Wing length, body length, wet weight, and length of the hind femur did not differ significantly (P 1⁄4 0.05) between the two morphs, but the pronotum of the brown form was significantly (t 1⁄4 4.539; df 1⁄4 9; P 1⁄4 0.029) longer than that of the green form (Table 3).
