A New Species

A new species of Salvia belonging to Salvia sect. Penellia from the state of Oaxaca is here described and illustrated. Only two species are included within this section: S. pennelli and the new species, S. robertoana. Both species are perennial herbs, with a 3-veined upper calyx lip, included stamens in the galea, late deciduous bracts, corolla tube epapillate inside, pubescent style and violet flowers. However, S. robertoana is distinguished from S. pennellii by its larger, elliptic to elliptic-oblong leaf blades (vs. blades lanceolate, oblong-lanceolate to oblong ovate) with tomentulose upper surface and pale, tomentose lower surface, and shortly decurrent base; usually longer inflorescence and shorter corolla tube and lower lip. A comparative table and an identification key of Salvia sect. Pennellia are provided.

A New Species

A new species of the genus Dictyanthus is herein described and illustrated, more than 30 years since the last paper describing new species of this genus. Dictyanthus stevensii sp. nov. is known only from the Zoque forest in the Chimalapas region in the state of Oaxaca, Mexico. This species differs from all other species because it has the smallest flowers within the genus. It is morphologically related to D. eximius, a microendemic species of Chiapas. Information on the distribution and habitat of this new species is given, and its conservation status is proposed as Critically Endangered B2ab(ii). An identification key to Dictyanthus species in southern and southerneast Mexico is also provided.

A New Species

In this study, we describe and illustrate Salvia fimbriaticalyx, a new species from Oaxaca, Mexico, which is morphologically similar to Salvia leptostachys, a species from section Angulatae. The new species differs from the latter by having persistent, lanceolate bracts with cuneate base; calyx lobes with a densely fimbriate margin; corolla tube longer (3–3.5 mm long), and the lower lip of the corolla shorter (3–3.5 mm long). Three molecular markers (ITS, trnL-trnF and trnH-psbA) were sequenced for the new species, and its phylogenetic position is discussed.

A New Species

Thygater Holmberg 1884, a Neotropical bee genus distributed from Argentina to Mexico, was last revised almost 50 years ago. Considering the species recognized then, and a few others described subsequently, 30 species are currently included in the genus. The Brazilian state of Minas Gerais is a large, environmentally heterogeneous territory, including areas in the phytogeographic domains of the Atlantic Tropical Rain Forest, the semiarid Caatinga and the highly seasonal Cerrado. The state insect fauna has been poorly sampled and studied. As part of a taxonomic and phylogenetic study of the genus, a synopsis of Thygater occurring in the state of Minas Gerais was produced, including the description of a new species (Thygater danunciae Freitas & Silveira, sp. n.), the recognition of two new synonymies, and an identification key for all 15 species of Thygater recorded for Brazil.

Salvia luteistriata, a new species from northeastern Sichuan, China, is described and illustrated here. The new species morphologically resembles S. maximowicziana, but it can be easily distinguished from the latter by having bigger maroon corolla with showy creamy-yellow vertical stripes in the internal ventral surface of corolla tube. Other diagnostic characters between them include that the new species has bigger leaf blade, longer bract and pedicel, bigger oblong upper corolla lip, and bigger mericarp. An identification key for the species in Salvia ser. Maximowiczianae, including S. luteistriata, is provided.

A new species of Heteropterys belonging to the Parabanisteria informal group is described for the savannas grasslands of the Serra do Tombador Natural Reserve, municipality of Cavalcante, State of Goiás, Brazil. Heteropterys rosmarinifolia is easily distinguished from the remaining Brazilian species of the Parabanisteria informal group due to its stems unbranched, leaves associated with the inflorescence verticillate, blades linear to very narrowly oblong, strongly conduplicate, ascending to upright, and sparsely sericeous to glabrous at age. We present a complete morphological description for the new species, photographic plates, comments on its distribution, ecology, and taxonomy, besides an identification key to the species of Heteropterys from the Parabanisteria group from the State of Goiás, Brazil.

Abstract—A new gesneriad species, Didymocarpus vickifunkiae is described here from the Indo-Burma biodiversity hotspot. The new species is morphologically similar to D. aureoglandulosus, but differs from it in having a corolla tube with indumentum, eglandular and ovate to oblanceolate bracteoles, slightly broader calyx lobes, and a bearded anther. We provide a detailed morphological description of the newly described species along with images and compare it with species that are morphologically similar to it. Here, we also lectotypify D. aureoglandulosus and provide a brief history on its collection and taxonomy. Finally, we provide a dichotomous identification key for all the Didymocarpus species from Mizoram, India.
