Nyctimantis rugiceps Boulenger, 1882 (Fig. 1A) is a Neotropical treefrog (Duellman & Trueb 1976; Faivovich et al. 2005) known only from disjunct localities in Amazonian Colombia, Ecuador, and Peru (Pérez-Villota et al. 2009). This species has the skin of the skull co-ossified and reproduces—including calling behavior, egg deposition and tadpole development—in water-filled tree or bamboo cavities (Duellman & Trueb 1976; Duellman 1978). Given its secretive behavior, this is a poorly known species and, as noted by Duellman (1978: 169), “the major clue to the life history of Nyctimantis is the calling behavior of the males”. Unfortunately, the only quantitative description of the advertisement call of N. rugiceps is a brief passage in Duellman (1978) based on four specimens from Santa Cecilia, Ecuador, where important variables are missing (e.g., call duration). More importantly, graphs illustrating the waveform and spectrogram are missing. Considering these limitations and the importance of advertisement calls to the study of anurans (Köhler et al. 2017), we provide a quantitative description using a call recording obtained in Leticia, Amazonas, Colombia.

Laboratory-raised grey tree frogs, Hyla versicolor LeConte, infected with either Trypanosoma andersoni Reilly and Woo or Trypanosoma grylli Nigrelli were fed on by laboratory-raised leeches, Batracobdella picta (Verrill). Trypanosoma andersoni multiplied by binary fission as sphaeromastigotes and epimastigotes in the gut of B. picta at 22 ± 1 °C. Some sphaeromastigotes and epimastigotes contained yellow granules. Two types of metatrypanosomes were found in the digestive tract of the leech at 24 days. Trypanosomes from leeches which had infected blood meals 35 days earlier were not infective when inoculated intraperitoneally or by the leeches feeding on laboratory raised H. versicolor. Trypanosoma grylli did not develop in B. picta at 22 ± 1 °C

A New Species

AbstractA new species of Scinax from the lowlands of the Atlantic Rain Forest remains in the southern region of the State of Bahia, North-eastern Brazil, similar to the S. auratus Wied-Neuwied, is described. This species is characterized by the following combination of characters: moderate size (males 23.0-27.1 mm SVL); snout rounded in dorsal view; dorsal colour pattern with dorsolateral yellowish stripe above greenish-brown background, with an interocular yellow transversal bar; vocal sac smooth; presence of a tubercle and dermal fold on tarsus advertisement call with four to five notes; call duration 0.17-0.24 s, dominant frequency 2.07-3.79 kHz. The advertisement call description and informations on natural history are provided.

We examined differences in morphology and advertisement calls of a large sample of frogs from the Australo-Papuan Region that resemble Litoria bicolor, and compared them with examples of that species from Australia. Consistent differences in body size, body proportions, and advertisement call structure among populations demonstrate that at least seven distinct species occur in the Australo-Papuan region, and that only the population represented by the holotype from the Northern Territory of Australia is Litoria bicolor s.s. Herein we describe four new species from the Papuan Region and comment on the origin and evolution of the Papuan members of the Litoria bicolor complex in the region.

Morphological Diagnostics

We quantitatively describe for the first time the advertisement call of Chiasmocleis (Syncope) carvalhoi using recordings  of five specimens from northern Peruvian Amazonia. The advertisement call is characterized by a single, short, tonal, and high-pitched note. Call duration ranges between 0.03–0.06 s and its dominant frequency between 7.12–7.92 kHz. The lack of pulses within notes distinguishes C. (Syncope) carvalhoi from all congeneric species except C. (Syncope) antenori, C. (Syncope) parkeri and C. (Chiasmocleis) mantiqueira, which can be distinguished by the shorter duration of their notes and silent intervals (in C. (Syncope) antenori and C. (Syncope) parkeri) and by the lower dominant frequency (in C. (Syncope) parkeri and C. (Chiasmocleis) mantiqueira). In addition, based on our collected specimens, we report on and discuss about the variation of some external morphological characters and natural history of C. (Syncope) carvalhoi, including the absence of vocal slits and sacs. Our study reveals a potential association between the absence of vocal slits and sacs, and tonal calls in Chiasmocleis, as well as conflicting morphological diagnostics characters in the literature.
