A New Species

We describe a new species of salamander of Bolitoglossa (Oaxakia) Parra-Olea, García-París and Wake, 2004 from the cloud forests of the central portion of the Sierra Madre del Sur highlands in the Mexican state of Guerrero. Bolitoglossa coaxtlahuacana sp. nov. is currently known only from the type locality and can be differentiated from other members of the group by morphological, coloration, and molecular evidence. With the description of this new taxon, the number of species in the subgenus Oaxakia increases to six.

A New Species

Eleutherodactylus uno n. sp . is described from the oak-pine zone of the Sierra Madre del Sur, in the Mexican state of Guerrero . The new species cannot be associated with any currently recognized supraspecific division within the genus and demonstrates the unsatisfactory nature of attempts to cluster the approximately 400 known species into groups.

Content of the dipsadid genus Rhadinaea has changed considerably since Myers’ 1974 revision. Three species groups are recognized currently in the genus. Our fieldwork in Oaxaca in June 2018 produced a single specimen of Rhadinaea considered to represent a new taxon. This new species is described from converted Premontane Wet Forest in the municipality of Santa Catarina Juquila in the Sierra Madre del Sur of southern Oaxaca, Mexico. It is most closely related to Rhadinaealaureata, from which it can be distinguished easily by color pattern and scutellation, and represents a species group distinct from the other three occupying the genus.

A New Species

The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well as the number of species was revised. We report here the discovery of a new species from Kon Tum plateau of the Truong Son (Annamite) Range of Central Vietnam, which we describe based on morphological and molecular evidence. Molecular phylogeny shows that the new taxon, G. (P.) wenlingae Hu, Cotton & Monastyrskii sp. nov., is sister to G. (P.) daiyuanae Hu, Zhang & Cotton, 2018 plus G. (P.) confucius Hu, Duan & Cotton, 2018. Molecular dating analysis further suggests that this new species diverged from its sister clade in the Pliocene (~3.5 million years ago). The new taxon constitutes the eighth and southernmost species of the mandarinus group.

A new species of Hechtia from the Mexican State of Tamaulipas is herein proposed as new: Hechtia hernandez-sandovalii, which is known only from the municipality of Villa de Miquihuana in the southwestern portion of the state. The new species is easily recognized by the following combination of characters: its white cotton-like indument (turning brownish with age) on the branches, rachis, and peduncle of both staminate and pistillate inflorescences. The new taxon is compared with H. glomerata, a species morphologically similar.

A New Species

Mexico has a rich woody bamboo flora with over 52 species, 66% of which are endemic. Mexico represents the northernmost extent for many Neotropical bamboo genera such as the widespread Rhipidocladum, a genus with characteristic fan-like branching and variable synflorescence morphologies. Only four species of Rhipidocladum are known from Mexico: R. bartlettii, R. martinezii, R. pittieri and R. racemiflorum. Remarkably, the ranges of all four species overlap in the Mexican state of Chiapas. During field work in Chiapas, a flowering population of Rhipidocladum was discovered that had two glumes and retrorsely scabrous abaxial leaf surfaces, and lacked foliage leaf fimbriae. This combination of characters is unlike that of any known species in the genus. We conducted a comprehensive morphological study of specimens from this population and confirmed the existence of a new species of Rhipidocladum. We describe and illustrate the new taxon, discuss its diagnostic characters and provide an updated key to the species of Rhipidocladum distributed in Mexico. This taxonomic novelty increases the richness of the genus to 20 species and adds a new endemic woody bamboo to the flora of Mexico. The new species inhabits montane cloud forest, an important yet threatened vegetation type in Mexico.

A New Species

A new species of Cyphophthalmi belonging to the New Caledonian endemic genus Troglosiro Juberthie, 1979 is described and illustrated using SEM, including the first description of a troglosironid ovipositor. T. longifossa sp. nov., known only from its type locality in Port Boisé, and found at low elevation near sea level, constitutes the seventh species of Troglosiro to be described to date. The new species has a unique disposition of the four ventral opisthosomal gland pores in the anterior portion of a long depression of the sternal segments 3 to 7. Information on other specimens recently collected in New Caledonia indicates that the number of described species in the island is a gross underestimate of the real diversity of New Caledonian Cyphophthalmi, both in number of species and morphology.

Chusquea is the most diverse among woody bamboo genera, with 174 described species. Not surprisingly, Chusquea is the most diverse bamboo genus in Mexico, and with the description of C. nedjaquithii the number of species will increase to 20, representing almost 45% of the total Mexican woody bamboo diversity. Based on fieldwork in the Mexican state of Oaxaca and revision of herbarium specimens we describe and illustrate C. nedjaquithii, a species endemic to the Sierra Madre del Sur in Oaxaca, Mexico. Chusquea nedjaquithii is similar to C. liebmannii but differs in having culms with deciduous hairs, an oblate central bud and fewer subsidiary buds, strongly geniculate branches in one row forming an incomplete verticil, oblique foliage leaf blade bases, and longer inner ligules in the foliage leaves. A key to the Mexican Chusquea species based on vegetative characters is provided.

A New Species

Recent botanical explorations in Sierra Madre Occidental in Durango, Mexico, led to the discovery of a new species which according to its morphology belongs to Salvia sect. Brandegeia. The new taxon is morphologically most similar to S. oresbia from central Mexico, against which it is thoroughly compared. Additionally, it is presented a synopsis of the section in order to provide updated and standardized descriptions for those species known only in base to their protologues, which allows a more detailed and precise comparison in respect to the new species. The morphological examination of the species in the section also revealed that the recognition of S. sharpii as a distinct species from S. blepharophylla is not justified; consequently, it is reduced to synonymy. An identification key, a distribution map, photographs, and a drawing of the new species are also presented.

Dasylirion micropterum is described as a new species from high elevations of the Sierra Madre Oriental in the Mexican state of Coahuila. It differs from known species of Dasylirion for having ascending dark green leaves, narrow inflorescences, small fruits with narrow wings and its distribution restricted to the western side of the Sierra Madre Oriental. The identity of the new species was confirmed through the sequence of matK and rbcL plastid DNA regions. GenBank sequences accessions are included. An illustration, photos and a distribution map are presented for the new species.
