A New Species

ThesiumnautimontanumM.A. García, Nickrent & Mucina, a new species from the Matroosberg Mt. of Western Cape Province of South Africa, is described and illustrated. This species shows several morphological features unusual for the genus including stem sympodial branching, indeterminate spicate inflorescences subtended by numerous bracts and fleshy, non-trichome tissue lining the inside of the corolla lobes. Molecular phylogenetic analyses using nuclear ribosomal internal transcribed spacer sequences place this taxon as sister to all African, Madagascan and South AmericanThesiumspecies. Given that only two proximal populations are known, this species is of conservation concern.

AbstractSerpentirhabdias viperidicus n. sp. (Nematoda: Rhabdiasidae) is described from the lungs of the ‘Brazilian lancehead’ Bothrops moojeni (Hoge, 1966) from the savannah in São Paulo State, Brazil. The new species is the eighth species of Serpentirhabdias described in the Neotropical region, and differs from other species mainly by a combination of characters: lips slightly notable, presence of fine striations at posterior ends, presence of two parallel lines with intercalated pores, a pore-shaped phasmid situated at the level of the anal aperture and another two in the posterior half of the tail. It is the first species of Serpentirhabdias reported in this snake host and the second species of this genus found parasitizing South American viperidian snakes. Molecular phylogenetic analysis using ribosomal (ITS and 28S partial) genes confirms Serpentirhabdias viperidicus n. sp. as a new species that clustered in the Serpentirhabdias clade, sister taxon to Serpentirhabdias fuscovenosa and Serpentirhabdias elaphe. This is the first description of Serpentirhabdias species from Brazil using molecular approaches and morphological characters to confirm the monophyly of this recent genus.

A New Species

In the course of a taxonomic revision of the genus Massonia Houtt., Massonia citrina M.Pinter, Deutsch, U.Müll.- Doblies & D.Müll.-Doblies, a new species of this genus from the Western Cape Province (South Africa), is here described. This species is similar to members of the M. depressa group, but it can be easily distinguished by its yellow filaments and style and the longer perigone-filament tube. A complete morphological description of the new species is presented.

Russula darjeelingensis is characterized by its small sized white pileus with a tall and narrow stipe, white spore print, basidiospores with amyloid suprahilar spot and a pileipellis containing encrusted pileocystidia and absence of primordial hyphae. The combination of all these characters and molecular phylogenetic analyses of internal transcribed spacer sequences of nuclear ribosomal DNA confirmed it as a new species in genus Russula Pers., subg. Russula Romagn. emend. sect. Polychromae (Maire) Sarnari subsect. Paraintegrinae Sarnari. A comprehensive morphological description, illustrations, and comparisons with morphologically similar and phylogenetically related species are provided in the present study.

Abstract— Ongoing research on the taxonomically complex genus Cheilanthes (Pteridaceae; Cheilanthoideae) has resulted in the identification of a new species from Loja Province in Ecuador, Cheilanthes ecuadorensis, described and illustrated herein. Originally collected in 1988 and identified as C. cf. rufopunctata, C. ecuadorensis is clearly distinct from that species in having pubescent adaxial blade surfaces and narrow, poorly-differentiated false indusia (rather than the glabrous adaxial surfaces and wide false indusia of C. rufopunctata). Among the South American species currently included in Cheilanthes, C. ecuadorensis is superficially most similar to C. pilosa. However, our molecular phylogenetic analyses indicate that C. ecuadorensis is sister to C. micropteris, the morphologically disparate generitype of Cheilanthes. Here we examine the phylogenetic relationships, morphology, cytogenetics, and geography of these four South American Cheilanthes species in a study that, once again, highlights the importance of herbaria in the process of new species discovery.

A new species―Lampranthus alboroseus―is described from the summits of two mountains in the Southern Cederberg of the Western Cape Province. Florally it resembles L. antonii but differs in having a creeping and mat-forming habit and in its overall smaller size. The creeping habit is shared with L. reptans which, however, develops noticeably longer pedicels.
