A New Species

Morphological characters of well-established taxonomic utility are infrequently examined for their relative phylogenetic consistency. Second only to characters of reproductive anatomy, jaw morphology and dentition commonly are employed as diagnostic characters for hirudiniform leeches, yet these features are highly variable across the group. Patterns of change were investigated for number of jaws and number of denticles per jaw in a phylogenetic context across 17 hirudiniform leeches representing three families. Phylogeny reconstruction employed 16 morphological characters, as well as two nuclear and two mitochondrial loci, and was evaluated with parsimony and likelihood. Rather than constrain the ancestral number of denticles to extant states, this meristic was optimised with squared-change parsimony. The degree to which dentition patterns were explained by phylogenetic relationships was assessed against a null distribution defined by permutation of extant states across terminals. Dentition was found to be non-randomly explained by phylogeny and, thus, corroborative of relationships among hirudiniform leeches as well as of the uniqueness of a new species of Oxyptychus described here from the Peruvian Amazon.

A New Species

The consumption of insects is a widespread practice among indigenous or native peoples of the Amazon. To assess the knowledge of the diversity of resources for entomophagy from the perspective of these peoples, testimonies or references about knowledge and feeding traditions of 100 people were collected in 37 localities in seven provinces of the department of San Martín in the basin of the Huallaga River. One cumulative species curve and the probability function of new species were estimated, then the probability of not finding a new species (99.5 %) to n100 was determined. The specimens that were captured in the field (54 %) were compared with representative specimens and databases, and the information provided by the participants was analysed to approximate the preliminary taxonomic locations of the remaining part of the sample. We found 46 resources for entomophagy and reported for first time in the Peruvian Amazon, the feeding with Chrysophora chrysochlora, Podalia sp., Lusura chera, and Cymothoidae, among others. Entomophagy is a deeply rooted practice in the native and riverine populations of the Huallaga basin, where Rhynchophorus palmarum, Rhinostomus barbirostris, Atta cephalotes sspp. and Brassolis sophorae were the most consumed for 78 % – 97 % of people. The least consumed species have the common characteristic of being scarce and they were part of the diet of the oldest segment in previous decades. At least 10 resources ceased to be consumed by the members of the sample. In addition to nutritional potential, the diversity of edible arthropod fauna represents complementary values for community health and cultural identity; however, most of these resources (87 %) are threatened and could disappear in brief time, as is the knowledge related to their use.

A New Species

A taxonomic revision of the South American genus Amburana comprised of three species is presented, including the new species A. erythrosperma which is described and illustrated. Amburana cearensis occurs widely in Argentina, Bolivia, Brazil and Paraguay.  Amburana acreana occurs in the Bolivian, Brazilian and Peruvian Amazon. Amburana erythrosperma is endemic to the southern Chapada Diamantina, Bahia, Brazil. The species are distinguished by the color of the stem, the number per leaf and shape of leaflets, the size of inflorescence, color and size of the standard petal, fruit with endocarp developed to form a papery wing surrounding the seed or this lacking, and color of seed. A key to the species is provided together with descriptions, taxonomic comments, geographical distribution maps and illustrations for each.  Lectotypes for A. acreana and A. cearensis are designated.

Abstract—A new species of Acianthera, A. lueri, is described and illustrated based on material collected in the Amazon region of Peru. The combination of the glabrous ovary, 3-lobed lip, and long-tailed petals distinguish A. lueri from similar A. lanceana. The new taxon is placed within the key to identification of species reported from the Peruvian Amazon region.

A New Species

The new species Platycarpum loretensis (Rubiaceae) is endemic to the Loreto Department, Peru, and restricted to white sand forests (varillal), palm swamps, and peatlands. It is similar to P. orinocense from which can be separated by the oblanceolate leaves with prominulous intersecondary veins (vs. elliptic to ovate, without intersecondary veins), corollas 1.9–3 cm long (vs. 1.2–2(–2.2) cm long), and fruits 4.7–5.5 × 3.6–4.9 cm (vs. 3–3.5 × 2.8–3.5 cm).

Meriania microflora (Merianieae, Melastomataceae), a new species en­demic to the Amazonas-Loreto border, in the Peruvian Amazon, is described and illustrated here. The new spe­cies presents the smallest flowers recorded within the genus, and also differs from other species of Meriania by the combination of appendages on the petioles, white petals, strongly dimorphic stamens and connectives with developed ascending appendages and multilobed descending appendages.
