Three new species of Licania (Chrysobalanaceae) from Peru.

ABSTRACT: Recent collections received for identification contain three conspicuous new species for the mid altitude forests of Amazonian Peru. Licaniapalcazuensis, Licaniaapiknae and Licaniamonteagudensis are described as new and their relationship to other species is discussed. A key is provided for all the species of LicaniasubgenusLicaniasectionLicania known to occur in Peru.

Project description:In this paper, we have described and illustrated three new species of Byrsopteryx from Peru: Byrsopteryx inti, sp. nov. Byrsopteryx mamaocllo sp. nov., and Byrsopteryx mancocapac sp. nov. Larvae of the latter two were also associated to male specimens based on comparison of a fragment of COI gene and pharate male identification. Byrsopteryx inti sp. nov. and Byrsopteryx mamaocllo sp. nov. share a unique feature: a semi-dome process formed by a thickened area on male forewings. The three species can be easily identified by wing coloration and male genitalia. Furthermore, Byrsopteryx inti sp. nov. can be recognized by its sternum VIII with a median digitate process on posterior margin, slightly capitate; and by long dorsolateral processes from segment VIII, which cross each other apically in dorsal view. Byrsopteryx mamaocllo sp. nov. can be distinguished by sternum VIII bearing a pair of short, posterior, spinelike processes, which are curved inwards and bordered by a rounded, membranous structure, and by a pair of short, heavily sclerotized, dorsolateral processes. Byrsopteryx mancocapac sp. nov. can be distinguished by strong spine-like processes arising dorsally from subgenital plate and by sternum VIII with posterior margin divided into two plate-like lobes. Larvae of B. mamaocllo sp. nov. and B. mancocapac sp. nov. are similar to other Byrsopteryx larvae known. They can be distinguished from each other by the shape of the operculum formed by terga VIII and IX, and number of setae on the second abdominal pleurite. Maximum likelihood analyses of 20 COI sequences, including nine Byrsopteryx species, placed B. inti sp. nov. and B. mamaocllo sp. nov. as sister species and related to a clade including B. gomezi, B. tapanti, and B. esparta, while B. mancocapac sp. nov. was found as sister to B. abrelata. Despite the close phylogenetic relationship found between B. inti sp. nov. and B. mamaocllo sp. nov., they are separated by 14.9% minimum K2P divergence of COI. The highest intraspecific distance observed was 1.4% for B. mancocapac sp. nov. individuals. Although the Peruvian caddisfly fauna has around 320 known species and almost a third of them are microcaddisflies, in this paper we present the first descriptions of Byrsopteryx species for the country.
