Review of specimens of Rudgea Salisb. (Rubiaceae, Palicoureeae) has discovered some species new to science and clarified the identity of one previously described taxon. Here we raise R. viburnoides (Cham.) Benth. subsp. megalocarpa Zappi of the western Amazon basin to species status, as R. megalocarpa (Zappi) Bruniera & C. M. Taylor. We also describe 11 new species found variously from lowland to montane elevations in Panama and western South America: R. barbosae C. M. Taylor from scattered locations on sandstone in Colombia; R. campanana C. M. Taylor from central Panama; R. cardenasii C. M. Taylor from the Caribbean area of northwestern Colombia; R. chocoana C. M. Taylor from the Pacific drainage of western Colombia and northwestern Ecuador; R. elegans C. M. Taylor from sandstone formations in the Andes of central Peru; R. homeieri C. M. Taylor from the Andean slopes of central Ecuador; R. inflata C. M. Taylor from the northwestern Amazon basin in Colombia and Brazil; R. retiniphylloides C. M. Taylor from northern to north-central Colombia; R. sanluisensis C. M. Taylor & Cogollo from the lower Río Magdalena valley of northern Colombia; R. suberosa C. M. Taylor & Bruniera from cloud forest and pajonal in the Andes from southern Ecuador through southern Peru; and R. zappiae C. M. Taylor & Bruniera from central western Ecuador.

This paper reviews Hippotis Ruiz & Pav. and Schradera Vahl, two Rubiaceae genera with centers of diversity in western South America. Both are inadequately known and in need of field study. Recent authors’ circumscriptions of H. albiflora H. Karst. and H. mollis Standl. are narrowed here, and four new species of Hippotis are described: H. antioquiana C. M. Taylor from northwestern Colombia, H. ecuatoriana C. M. Taylor from central-southern Ecuador, H. elegantula C. M. Taylor & M. Calderón from the western Amazon basin in Ecuador, and H. vasqueziana C. M. Taylor from lowland northeastern Peru. Four new species of Schradera Vahl are also described here: S. cernua C. M. Taylor and S. francoae C. M. Taylor from western Colombia, S. condorica C. M. Taylor & D. A. Neill from southern Ecuador, and S. morindoides C. M. Taylor from southern Ecuador and northern Peru. Schradera condorica at least sometimes is a free-standing tree, a habit newly documented for this genus.

Stenonartonia is a neotropical genus restricted to the forested regions of South America east of the Andes. The genus is revised here and numbers 14 species. Nine new species S. hasyva sp. nov., S. perdita sp. nov., S. cooperi sp. nov., S. guaraya sp. nov., S. rejectoides sp. nov., S. occipitalis sp. nov., S. tanykaju sp. nov., S. hermetica sp. nov., S. grossa sp. nov. are discribed and illustrated. New combination is proposed for S. mimica (Kohl), comb. nov. (from Paranortonia). Lectotype is designated for Nortonia polybioides von Schulthess. A key, along with full descriptions, illustrations of morphological features and distribution maps for all of the species are given.

A New Species

Elachistocleis is a Neotropical genus of microhylid frogs with 18 species, most of which occur east of the Andes in South America. Here, we present a new phylogeny of Gastrophryninae and describe and name a new species of Elachistocleis from southern Ecuador—the first to be found west of the Andes and also the first from Ecuador. Our phylogeny is based on DNA sequences of the mitochondrial genes 12S rRNA, 16S rRNA, COI, and the nuclear genes BDNF, cmyc2, H3A, 28S, SIA1, and Tyr. Elachistocleis araios sp. n., is the sister species of all other Elachistocleis. The finding of this taxon highlights the probability of the existence of more Elachistocleis species west of the Andes.

Two New Species

Two new species of Juncus from South America are described, illustrated, and a key is provided to separate the two species from related South American species in Juncus sect. Ozophyllum. Juncus andinus is similar to J. ecuadoriensis from Venezuela, Colombia, and Ecuador, but is different in having smaller seeds and conspicuous cataphylls; it is distributed in the Andes from southern Ecuador to southern Peru. Juncus austrobrasiliensis, from Brazil, resembles J. micranthus but differs in having smaller, castaneous flower-heads and capsules with beaks that clearly protrude from the flower; it is distributed in southern Brazil from São Paulo to Santa Catarina.

These two quotations, dating to within almost a decade of each other, refer to very different parts of South America, the first the La Guajira Peninsula at its northern tip, the second the savannahs of the Gran Chaco at its very heart. The Wayúu, dwelling in the first, had no direct connection with the Mbayá of whom Dobrizhoffer wrote here (though he is more famous for his work on their cousins, the Abipones). Nevertheless, both regions shared aspects of their respective experiences of colonial intrusion and settlement: the frequent adoption not just of horses but also of other exotic species like cattle and sheep; Spanish use of missionaries to try and pacify their Indigenous inhabitants; and the fact that the latter could play off one European power, or Spanish province, against another, thereby maintaining their own freedom of action. Aiding the Native peoples in this was their geographically, politically, and economically marginal position with respect to the main foci of colonial power in the Andes and along the Atlantic. Spain began exploiting Venezuela’s pearl fisheries as early as 1508, even settling on the mainland from 1522, but the real impetus to conquest in South America came only with Francisco Pizarro’s invasion of the Inka Empire in 1533. The highlands of Peru, Bolivia, Ecuador, and Colombia (the latter never part of Inka domains), the lowlands between them and the Pacific Ocean, the northern half of Chile, and the northwestern corner of Argentina all passed quickly—if not always easily—under Spanish control. So too did parts of Paraguay, settled by following rivers inland from the Atlantic. Portugal, on the other hand, secured for herself the coast of Brazil, eventually expanding her reach across virtually the entire Amazon Basin. Horses were as much a part of the conquistadores’ repertoire in South America as in Mexico. They sowed panic when Pizarro first confronted Inka troops at Cajamarca in 1533, but Native American surprise and fear did not last. Inka armies quickly devised tactics to neutralize the effects of horses on the battlefield in vain efforts to expel the invader.

Molecular Characters

Many of the species classified in Psychotria L. subg. Heteropsychotria Steyerm. (Rubiaceae), including the species of Psychotria ser. Axillares (Hook. f.) Steyerm., have been shown to belong to Palicourea Aubl. based on morphological and molecular characters. This section is now treated as Palicourea sect. Axillares (Hook. f.) Borhidi, and includes 14 species found from southern Central America through the Andes of northwestern and western South America with a center of diversity in eastern Colombia and western Venezuela. This section is characterized by the combination of laminar, well-developed, bilobed stipules and mostly capitate, pseudoaxillary or sometimes terminal, mostly sessile inflorescences with numerous well-developed bracts that enclose the flowers but without enlarged involucral bracts. It is circumscribed differently here than it is by Borhidi. The nomenclatural summary, key, and diagnostic discussions that separate the species included here are based on several new taxonomic circumscriptions. No infraspecific taxa are recognized in Pal. axillaris (Sw.) Borhidi, but one of its varieties from Venezuela is raised to species status as Pal. villipila (Steyerm.) C. M. Taylor. The circumscription of Pal. rosacea (Steyerm.) Borhidi is expanded, and four species are newly described here: Pal. aristata C. M. Taylor from the Andes of southern Ecuador, Pal. quibdoana C. M. Taylor from northwestern Colombia, Pal. santanderiana C. M. Taylor from the Andes of eastern Colombia, and Pal. winfriedii C. M. Taylor from northern Venezuela.

A New Species

We describe a new species of Anolis lizard from the Pacific slopes of the Andes of southwestern Ecuador at elevations between 372–1,000 m. The new species belongs to the Dactyloa clade and may be distinguished from other Anolis by size, external anatomy, mitochondrial DNA divergence, and dewlap color. Based on phylogenetic analyses of mitochondrial and nuclear DNA sequence data, we found that the new species is sister to A. fraseri in a clade composed primarily of large Dactyloid species. The new species is known from a protected area in southern Ecuador, Buenaventura Reserve, which suggests that at least some its populations are well protected.

Odontostilbe pulchra, previously considered species inquirenda in Cheirodontinae and doubtfully assigned from the río Orinoco basin, is redescribed with the rediscovery of two syntypes. Originally described to the Island of Trinidad, O. pulchra is widespread in Venezuela, the río Orinoco basin, in smaller coastal drainages of northern South America, in the Lake Valencia system, and río Essequibo basin. A punctual occurrence in the upper rio Negro, near southernmost headwaters of the río Orinoco, extends its distribution to the Amazon basin. Additionally, two new species of Odontostilbe from the río Orinoco basin are described.

A New Species

We describe a new species of Noblella from the western slope of the Ecuadorian Andes. The new taxon is distinguished from all other species in the genus by lacking dorsal marks (i.e., interobital bar, scapular and sacral chevrons) and by having a bright orange venter. The new species and Noblella heyeri are the only species of Noblella reported in the Pacific Andean versant. We provide an osteological description of the new species and a key for the species in Noblella.
