Gephyromantis marokoroko Hutter, Andriampenomanana, Andrianasolo, Cobb, Razafindraibe, Abraham and Lambert, 2022: 486

Note.

A recently described species from the Northern Central East of Madagascar (Hutter et al. 2022) that is genetically and morphologically distinct by a reddish iris, gray to whitish vocal sacs and large femoral glands with 7-8 distinct, externally visible gland granules, and a dorsal skin texture consisting mainly of sharp ridges rather than of rounded tubercles (Fig. 11). A tibial gland is absent. According to the original description, SVL is 24.0-27.0 mm in males and 23.9-24.6 mm in females. The species is so far only known from several sites near Andasibe: Belakato in Andasibe-Mantadia National Park, Vohimana, Vohidrazana (type locality) and Tavalobe near Vohidrazana. We reanalyzed the call of G. marokoroko to ensure full comparability with the call descriptions of all other Laurentomantis .

Call.

The advertisement call was recorded on 6 January 2016 at Vohidrazana (air temperature 20.4°C; call voucher KU 343230 [CRH 1110]). It consists of a series of short distinctly pulsed notes of variable duration (Fig. 12). There is recognizable amplidude modulation within each call, with call energy being greatest at approximately 60% of the call’s duration, with initial notes being the least energetic ones. Within calls, notes are repeated at constant intervals. Each note contains a certain number of clearly separated pulses repeated at an approximate rate of 150-170 pulses/second. Numerical parameters of 3 analyzed calls are as follows (range followed by mean ± standard deviation in parentheses): call duration 557-1203 ms (968.7 ± 357.7 ms); note duration 10-26 ms (17.4 ± 5.0 ms); number of notes per call 12-28 (21.0 ± 8.2); note repetition rate within calls 18.2-19.6 notes/second (18.8 ± 0.6 notes/second); pulses per note 2-5 (3.3 ± 0.9); dominant frequency 2411-2476 Hz (2444 ± 28 Hz), with a second peak of almost equal energy at around 3600-3700 Hz; prevalent bandwidth 1000-5200 Hz. Call repetition rate in short call series (containing 3 calls) approximately 18-20 calls/minute.
