Leptobrachella oshanensis (Liu, 1950)

Advertisement call. Figures 4 A-E; Table S4. Calls recorded at temperature 19 to 22 oC. Description based on five sequenced adults (Tables 1 and S4). Five call types were found, but a typical call series consists mainly of type B and/or type C. The first type (A) consists of repeated short notes; the second type (B) consists of two repeated short pulses separated from each other by a silent interval longer than its note interval; third type (C) consists of one short note and one following longer note; the fourth type (D) contains four notes, anterior three short, the last longer; the fifth (E) consists of long repeated notes. Type B and/ or C consist main part a typical call series, while A, D and E are relatively fewer. Dominant frequency of all type of calls ranges from 4000.0 Hz to 4500.0 Hz. Dominant frequency of type B (4367.6 ± 179.2) Hz, type C (4383.9 ± 191.7) Hz, and type D (4481.3 ± 81.7) Hz slightly higher than that of type A (4276.6 ± 139.8) Hz andtypeE(4203.5±172.7)Hz.TypesAandEaremoresparsely distributed in call series than other types, the inter-call intervals much longer (average 1040.3 ms to 1629.5 ms vs. 130.8 ms to 266.6 ms). Harmonic 1 and 2 are common, present on 99% and 70% of calls, harmonic 3 are much rare, only 1.7%. Amplitude of notes of call type A largest at first pulse, drastic reduce in following pulses; second note of type B possess amplitude larger than that of first note, and first pulses of two notes with largest amplitude; the second note of call type C with larger amplitude than the first note, amplitude reduce gradually on second note while radically on most first note; the second note of a typical D call type with largest amplitude, then gradually reduce in following notes; the amplitude of pulses of call type E are similar at beginning and end.
