Locusta niponensis

Species group niponensis (Haan, 1843)

Diagnosis (species group “a”). The species studied here within the species group possesses the widest tegmina, comparatively long files (Fig. 5 a–f) and widest mirrors (Fig. 6 a–e). The file is widest in middle, from which teeth are gradually narrowed toward both ends (Fig. 5 a–f).

Bioacoustics. One song unit is composed of several continuous syllables (Fig. 1). This species group possesses 5 song types (Fig. 1, Table 2). The song types of M. himalaya sp. nov. and M. marmorata He are distinguished from other three types by the repeated syllables without amplitude change (Fig. 1 p–q, s–t). In the other three types, one song unit could be separated into three phases, i.e., low-amplitude beginning and ending phases, and high-amplitude middle climax (Fig. 1 a–d, f–i, k–n).

Included taxa. M. niponensis (East Asia), M. fallax He, 2019 (China), M. crescendo sp. n. (China), M. himalaya sp. n. (China), and M. tibetensis sp. n. (China), and M. marmorata He, 2019 (China).
