Population dynamics, seasonality and sex ratio of twig-girdling beetles (Coleoptera: Cerambycidae: Lamiinae: Onciderini) of an Atlantic rain forest in south-eastern Brazil

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.

Continuous Reproduction

The present study investigated the reproductive biology of the pink shrimp Farfantepenaeus brasiliensis and Farfantepenaeus paulensis captured offshore and at two important fishing grounds, Guanabara Bay and Araruama Lagoon both on the south-eastern Brazil coast. The females’ size at first maturation was 37.90 mm of carapace length (CL) for F. brasiliensis and 41.95 mm of CL for F. paulensis. Both species presented continuous reproduction with two spawning peaks. For F. brasiliensis these peaks occurred during summer and winter and for F. paulensis during summer and autumn. The sex-ratio of the pink shrimp was favourable to the number of females which can be a strategy to guarantee the reproduction.

A New Species

A new species of the genus Rhinella is described from Canavieiras, southern State of Bahia, in the Atlantic Rain Forest of Eastern Brazil. Rhinella hoogmoedi sp. nov. is characterized by the medium size for the genus (SVL 39.4-52.1 mm in males), snout rounded in dorsal view, with a vertical apical ridge which gives a nearly mucronate aspect, and nearly acute in profile, antorbital and supra-orbital crests developed, parietal crest poorly developed, post-orbital crest large, forming a small lateral ledge, tympanum evident, vertebral apophyses not salient on dorsum, presence of a dorsolateral line of pointed tubercles on the external border of the parotoid gland, continuing along the lateral side of body to the groin, a rounded tubercle at the posterior corner of mouth, and vocal slits present. The new species is distributed from the State of Ceará to the State of Paraná, Brazil.
