In this paper, we describe two syntopic species of Adenomera from the
Chapada dos Veadeiros microregion, northern State of Goiás, central
Brazil, recognized based on morphology, color patterns, and bioacoustics.
Specimens and calls were obtained in the Municipality of Teresina de
Goiás, central Brazil. Adenomera cotuba sp. nov. is diagnosed from the
other 16 congeneric species by its 1) small size (adult male SVL 18.6–20.5
mm) and very robust body; 2) dorsum glandular/granular with no distinctive
dorsal granular rows or dorsolateral folds; 3) black or very dark dorsal
coloration with no distinctive color patterns (e.g., dorsolateral or
vertebral stripes); 4) toe tips not developed into flattened disks; 5)
presence of antebrachial tubercle; and 6) advertisement call consisting of
a well-defined series of pulsed calls (7–32 calls/series) with progressive
increment in amplitude in the first third of each call series when it
reaches a sustained plateau. Adenomera juikitam sp. nov. is diagnosed from
the other 16 congeneric species by its 1) dorsum profusely
glandular/granular with no distinctive dorsal granular rows or
dorsolateral folds; 2) dorsum with a marble-like and red coloration with
no distinctive color patterns (e.g., dorsolateral or vertebral stripes);
3) toe tips not developed into flattened disks; 4) small size (adult male
SVL 19.1–19.5 mm) and very robust body; and 5) long (148–202 ms)
advertisement call composed of 16–21pulses. Both new taxa occur in
syntopy, and our data allow us to differentiate them both in temporal
(pulses/call) and spectral (frequency peaks) traits of their advertisement
calls. Besides, dorsal coloration is distinctive, Adenomera cotuba sp.
nov. has a black or very dark-colored dorsum, whereas Adenomera juikitam
sp. nov. has a marble-like and red-colored dorsum, in addition to the
presence (A. cotuba sp. nov.) or absence (A. juikitam sp. nov.) of
antebrachial tubercle.
