Two new Andinia species are described, A. barba-caprina and A. crassipetala, both found during a botanical expedition to the montane forests of the Central Cordillera of the Peruvian Andes. They are compared with morphologically similar species, and Lankester Composite Dissection Plates (LCDP) are provided. Andinia barba-caprina is more similar to A. tingomariana but is distinguished by having obovate sepals with sparsely erose margins and the lip with narrowly obtuse, short basal lobes and a group of large hairs on the abaxial surface. Andinia crassipetala is distinguished from the two most similar species, A. hernandoi Est.Domínguez & S.Vieira-Uribe and A. persimilis (Luer & Sijm) Karremans & S.Vieira-Uribe for having thick, deltate and obtuse petals.

Two New Species

Two new species of Graffenrieda are described from the Amazon rainforest. Graffenrieda maturaca is characterized mainly by its leaves which are dull on the adaxial surface, chartaceous, narrowly elliptic to oblanceolate, and apparently uni-nerved, with only the median acrodromous vein evident. This species has been collected only at Serra de Maturacá, in the state of Amazonas, Brazil. Graffenrieda goldenbergii is distinguished mainly by the pulverulent, whitish, early caducous indumentum of the rachis, pedicel, hypanthium and calyx, by the abaxial surface of the leaves which is moderately lepidote, with trichomes ca. 0.2 mm diam., by the irregularly valvate calyx, and by the membranaceous, costate, not sulcate fruits. This species has been collected in the state of Acre, Brazil, and in the Province and District of Lama in Peru. Both species are illustrated, compared with similar species, and their conservation status is discussed.

New Guinea is home to the world’s most diverse insular frog biota, but only a small number of taxa have been included in genetically informed assessments of species diversity. Here we describe two new species of New Guinea treefrog in the genus Litoria that were first flagged during assessments of genetic diversity (DNA barcoding) and are currently only known from the holotypes. Litoria pterodactyla sp. nov. is a large green species in the Litoria graminea species complex from hill forests in Western Province, Papua New Guinea and is the third member of this group known from south of the Central Cordillera. Litoria vivissimia sp. nov. is a small, spike-nosed species from mid-montane forests on the Central Cordillera. It is morphologically very similar to Litoria pronimia, but occurs nearly 1000 m higher than any known locality for that species. More extensive genetically informed assessment of diversity in New Guinea frogs seems certain to reveal many more as-yet-unrecognised taxa in complexes of morphologically similar species.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Two unusual species of Craterellus have been collected numerous times from the evergreen tropical forests in Kerala State, India. The species Craterellus albostrigosus and Craterellus inusitatus are described as new based on morphological and phylogenetic analyses of nrLSU-rDNA gene region. Complete morphological descriptions, photographs and comparisons with similar species are provided as well as a key to the known species of Craterellus from India.

Two New Species

Unclear boundaries between species hinder identification in the field and in herbaria, especially in species groups that can only be distinguished on the basis of subtle morphological and ecological features. One such taxon is Ficinia indica, widespread in the Greater Cape Floristic Region, growing on deep sandy soils between sea level and 1000 m elevation. Within its range, several phylogenetically related and morphologically similar species co-occur or occupy distinct habitats. Studies in herbaria show species in the Ficinia indica complex to be largely misidentified based on the use of qualitative information. Here, we investigate whether the six taxa recognized, based on one or a few characters, are supported as distinct species based on multivariate analysis of macro-morphological data. Two of the taxa were mostly separated whereas the other four taxa overlapped in multivariate space, but all the taxa could be distinguished using a single or a combination of morphological and ecological characters. We uphold the four previously recognized taxa (Ficinia argyropus, F. elatior, F. indica, F. laevis) as species, describe two new species (F. arnoldii and F. montana), and provide a dichotomous key for their identification.

Frequent biodiversity sampling and monitoring programs often lead to relevant taxonomic findings. Here, as a product of different field expeditions to two places in the northern Andes, we discover and describe two new species of rain frogs of the genus Pristimantis from the cloud forests of the Central Cordillera of Colombia. Pristimantis chocolatebari sp. nov. is diagnosed by having the following character states: dentigerous process of vomer triangular, snout large and protruding, dorsum smooth, vocal slits and vocal sac present, groin and hidden part of the thighs yellow. Pristimantis carylae sp. nov. is diagnosed by having iris copper red, dentigerous process of vomer oval, snout short and rounded, dorsum finely shagreen with scattered tubercles, double nuptial pad in males, groin and hidden part of thighs pink. We also infer, for the first time, the phylogenetic position of P. permixtus, P. platychilus, and two candidate new species. In addition, we emphasize not to use genetic distance as the only source of evidence for species delimitation, considering the high intraspecific diversity found in one of the species described here. Finally, we highlight the relevance of different habitat and ecosystem conservation strategies to promote amphibian diversity studies in the Andes.
