Agave garciaruizii (Asparagaceae) a new species from the Chorros del Varal State Reserve in western Mexico

A new species named Agave garciaruizii is described and illustrated here. A. garciaruizii is endemic to tropical dry forest in the Itzícuaro and Apupátaro river canyons in the Chorros del Varal State Reserve, at the southern border of the states of Jalisco and Michoacán, México. It belongs to the subgenus Littaea and to the Marginatae species group and is morphologically related to A. angustiarum and A. impressa, but differs from these species in some features of leaves, inflorescences and infructescences. Its conservation status was assessed as Endangered (EN). Additionally, morphological evidence was provided in support of A. arcedianoensis as a species distinct from A. angustiarum. A key to morphologically and geographically closely related species in the Marginatae group is presented.

A New Species

Background and Aims: In Mexico, Coulteria is a morphologically diverse genus, having many endemic species in the country. Despite its diversity, species delimitation and circumscription are not fully documented. Botanical explorations in central Mexico during the last 25 years have resulted in the discovery of several new legume taxa in the Río Balsas Depression. A new species of Coulteria from the Western Río Balsas Depression is here described and illustrated.Methods: During fieldwork, morphological studies and electron microscopy analysis of the already species described of Coulteria, we detected a new species in the Infiernillo area of Guerrero and Michoacán, Mexico. For the new species, we estimated its conservation status based on extent of occurrence (EOO) and its area of occupancy (AOO) using the GeoCAT software, applying the categories and criteria of the IUCN Red List.Key results: Coulteria delgadoana, a new species of Caesalpinioideae endemic to the seasonally dry forest of Guerrero and Michoacán (Western Río Balsas Depression), Mexico, is described and illustrated based on morphological evidence. Coulteria delgadoana has long male inflorescences up to 15 cm long, small flowers, leaves with glabrous leaflets and prominent reticulate venation, and a glabrous chestnut brown fruit with purplish tints. Based on IUCN criteria, we suggest an Endangered (EN) category of the species.Conclusions: Morphological characters of the new species C. delgadoana, suggest that it is similar to C. glabra, a species from Colima and Jalisco. The long size of the male inflorescence has not been observed in other Coulteria species. Coulteria delgadoana shares its distribution area with C. lewisii in Infiernillo.

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

We describe a new species of Ololygon from the Cerrado biome, Central Brazil. The new species is assigned to the Ololygon catharinae species group based in morphological attributes. Ololygon goya sp. nov. in known only from type locality—Sítio d’Abadia municipality, State of Goiás—and associated with riparian environments connected to seasonal dry forest on the banks of the Corrente river, a tributary of the Paranã river basin. The new species is characterized by the combination of the following characters: medium size (24.4–38.8 mm SVL); snout subovoid in dorsal view; canthus rostralis well defined; males with hypertrophied forearms and nuptial pads; inguinal region and hidden surfaces of thigh with irregular dark brown spots on pale yellowish background. We also describe the external morphology and oral morphology of tadpoles, and the advertisement calls of the new species.

A New Species

Population declines and range contractions among Australian frogs that commenced in the early 1980s continue in some species that were once widespread. The generality of this pattern has been difficult to discern, especially for those species that are encountered rarely because they have restricted periods of calling activity with poorly defined habitat preferences, and are not common. Several lines of evidence indicate that Litoria littlejohni is such a species. This frog was once known from mid-eastern New South Wales to eastern Victoria, and evidence from wildlife atlas databases and targeted searches indicate that it has declined in large portions of its former range, leaving several populations that are isolated, in some cases restricted in distribution, and of small size. We investigated the relationships among populations using mitochondrial ND4 nucleotide sequences and single nucleotide polymorphisms (SNPs) from the nuclear genome. We found that northern and southern populations form two highly divergent genetic groups whose distributions abut at the southern margin of the Sydney Basin Bioregion and these genetic groups also show divergence in morphology and male advertisement calls. Here we describe the populations to the south of the Sydney Basin Bioregion as a new species and provide information on its distribution and ecology. In light of the apparent isolation and small size of known populations of the new species and the consequent restriction of the range of L. littlejohni, we assessed the conservation status of both species.

A New Species

Background and Aims: Bactrospora is a genus of crustose lichens characterized by its black, verrucose to denticulate and little apothecia, and mostly acicular, or sometimes muriform spores, longer than wide. The genus is represented by 38 accepted species. The aim of this work is to describe Bactrospora totonacae, a new species from the tropical dry forest of Veracruz, Mexico. Methods: The specimens were collected on the “Cerro de los Metates” in the municipality of Actopan, Veracruz, Mexico. Macrochemical tests, UV reaction, and a thin layer chromatography were performed; likewise, the presence of amyloid substances distributed in the thallus and ascomata was verified with Lugol’s solution. The voucher is deposited in the herbarium XALU of the Facultad de Biología of the Universidad Veracruzana. Key results: The new species Bactrospora totonacae is characterized by the pruine K+ reddish magenta in its disc. Conclusions: The described species is unique in Bactrospora because the combination of pruine K+ reddish magenta and a thick carbonized exciple has never been reported in this genus.

Iucn Criteria

Epitypes are proposed for two species of Hechtia: H. subalata and H. jaliscana, both endemic to Western Mexico. The holotypes of both species consist of fruiting specimens. While the female flowers of both species are extremely similar, the staminate ones are noticeable different: we select staminate vouchers as epitypes to clearly circumscribe both taxa. As a result of the delimitation of the concept Hechtia subalata and its geographical distribution, we identify a new species from Durango, Mexico, previously misidentified as Hechtia subalata: Hechtia marthae. We provide images portraying plant parts of all species, as well as photographs in habitat. Finally, assessments of the conservation status of the three species sensu IUCN criteria are included.
