High Diversity

A new species of Spigelia (Loganiaceae) from Oaxaca, Mexico, is described here. This species is similar to S. humboldtiana and S. anthelmia, due to its size and white flowers, but the leaf texture, phyllotaxy below the inflorescence, and the style length are characters that allow to recognize it as a new species. With this addition, Mexico reaches a total of 23 species of the genus, of which more than 50% are endemic or microendemic. This places the country as the second area of high diversity after Brazil. A detailed description and illustration of the new species, a dichotomous key and a distribution map of Spigelia species in Oaxaca are included.

We describe Dinacoma sanfelipe sp. nov. from southern California, the first new species belonging to the melolonthine scarab beetle genus Dinacoma Casey, 1889 (Scarabaeidae: Melolonthinae: Melolonthini) to be described in 90 years, based upon examination of 141 specimens of that genus. Diagnostic comments, a dichotomous key, photographs of all species of Dinacoma, and a distribution map are presented to facilitate the identification of adult male specimens.  One species in the genus is federally listed under the United States Endangered Species act, and all known species may be of conservation concern. Key words: Scarabaeoidea, Melolonthini, scarab beetle, insect conservation, cryptic species

A new species, Miersia putaendensis (Amaryllidaceae), endemic to Central Chile, is described. The new species differs from all known species of Miersia by featuring a white staminal tube with a purple spot and two upper linear, cuneiform floral appendages directed towards the front in its frontal lobe, the apex of which is toothed and deflexed. It inhabits southern slopes of sclerophyll woodlands and scrubs, particularly along rocks. Currently, the species is critically endangered. A detailed description, illustration, distribution map of the new species, and a dichotomous key with all accepted species of Miersia are provided.

Iucn Criteria

In the last decade, several species of magnolias have been described for Guatemala, five of which are found in Alta Verapaz, where, during an exploratory survey, we found a specimen that did not correspond morphologically to any previously reported species. To obtain material and determine phenology, several individuals were monitored for a year. Here, we describe this as a new species of Magnolia subsection Magnolia (Magnoliaceae). It is distributed in the cloud forest of San Cristóbal Verapaz, Alta Verapaz, and is culturally important for the local villagers. It differs from other similar species, M. montebelloensis and M. tribouillierana, in having an abruptly acuminate leaf apex (drip tip), larger flowers, purple staminophores and more stamens, among other traits. According to IUCN criteria, M. poqomchi is critically endangered [B1ab (iii), B2ab (iii)]. Additionally, we include a dichotomous key and distribution map for the genus in Guatemala. Taking this record into account, there are a total of ten native species reported for Guatemala, making it an important centre of species diversity for magnolias.

A New Species

Polystachya orophila, a new species of Orchidaceae, is described based on specimens collected during the baseline study of the Guinean Nimba Mountains for the environmental impact assessment for a proposed mining project. While material belonging to this species was mentioned as early as 1920 by Chevalier, it has historically been confused with P. microbambusa, from which it differs by its typically Polystachya-like clustered pseudobulbs, placing it in P. sect. Polystachya, whereas P. microbambusa has pseudobulbs successively growing on top of one another, forming developed and persistent stems, and is the sole representative of P. sect. Dimorphocaules. The complex taxonomic and nomenclatural history of P. microbambusa is also clarified. For both taxa we provide a morphological description as well as information on distribution, habitat, and phenology, an IUCN conservation status assessment using the Red List criteria, and a distribution map, along with a dichotomous key that also includes the most similar members of P. sect. Polystachya.

A New Species

Senecio festucoides is described from northern Chile. The new species is morphologically similar to the discoid caespitose Andean species and belongs to the subgroup displaying yellow corollas and yellowish anthers and style branches. It is characterized by a weak, not self-supporting stem, narrowly linear leaves, long pedunculate capitula with (17–)21 involucral bracts, and minutely papillose achenes. Among other characters, the color of the corollas, anthers, and style branches and the number of involucral bracts differentiate it from S. scorzonerifolius, which is the morphologically closest species. The new species thrives in the desertic Puna ecoregion and grows amongst tufts of Festuca chrysophylla (Poaceae). Detailed pictures of living plants are provided, as well as a distribution map and a dichotomous key to the discoid caespitose Senecio species from northern Chile.

Comolia abaetensis, an endemic new species from the Abaeté and Itapuã sand dunes, Bahia, Brazil, is described and illustrated. Additionally, field images and a geographic distribution map of the new species are provided, together with morphological and leaf anatomy comparisons among the most similar congeners, and a dichotomous key to the species that occur in Brazil. Comolia abaetensis is morphologically similar to C. ovalifolia, but differs from the latter by the following combination of characteristics: glabrous (rarely with sparse trichomes)internodes and hirsute nodes, glabrous leaf blades or rarely with sparse eglandular trichomes, abaxial surface predominantly red with green nuances, glabrous pedicels, cupuliform hypanthium, and filaments of the antesepalous stamens that are 5–6 mm long. Specimens of C. abaetensis have been confused with and/or tentatively determined as C. berberifolia. However, these two species are readily distinguished by the size of the leaves, the length of the trichomes and filaments, and the color of the abaxial foliar surfaces. Comparisons between the leaf anatomy ofC. abaetensis and C. ovalifolia are provided and the occurrence of emergences and hydathodes are here reported for the genus for the first time. Finally, we informally recommend a conservation status of Critically Endangered [CR B1ab (iv) + 2ab (iv)] for C. abaetensis.

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.
