Two new species of Aiphanes from Colombia, Aiphanes buenaventurae and Aiphanes multiplex, are described and illustrated. Two other species, Aiphanes killipii and Aiphanes concinna, previously included in synonymy under Aiphanes horrida, and Aiphanes lindeniana, respectively, are restored. Aiphanes stergiosii described from Venezuela is included in synonymy under Aiphanes lindeniana. An epitype is designated for Aiphanes simplex.
Key words. Arecaceae, Aiphanes, Colombia, Venezuela.

After the publication of our monograph of the palm genus Aiphanes (Borchsenius & Bernal 1996), several changes in our understanding of the group have taken place, which make it necessary to re-evaluate the circumscription of some of the species recognized at that time. The discovery of several new species (Bernal 2001, Galeano & Bernal 2002, Cerón & Bernal 2004) has revealed that narrow endemism in the genus is more common than previously appreciated. On the other hand, new collections and the study of older ones not previously available to us have emphasized the need for a general update of the taxonomy of the genus. In the following we describe two new species and reassess the taxonomic status and delimitation of three others. Finally, an epitype is designated for Aiphanes simplex Burret.
Aiphanes buenaventurae R. Bernal & Borchs. sp. nov. Fig. 1a-b
Type. COLOMBIA. Valle del Cauca: Buenaventura, 6 May 1926 (fl), O. F. Cook 86 (holotype, US).

Leaves 5-8, spreading; sheath ca. 22 cm long, with a thin indumentum of brown scales and with brown and yellowish bicolor spines to 3 cm long; petiole ca. 25 cm long, with scales like the sheath, with only a few scattered bicolor spines to 5.5 cm; rachis 78 cm long, adaxially ridged, abaxially with a scaly indumentum like that of the sheath, covered on both sides with a dense indumentum of brown spinules ca. 0.5 mm long, armed only toward the base with a few bicolor spines to 2 cm; pinnae 8-13 on each side, subregularly arranged in one plane, except for a basal group of five rather closely arranged pinnae, middle pinnae separated 7-11 cm, plicate, narrowly cuneate to almost linear, 4-13 times as long as wide, oblique to incised-premorse at apex, often with a 1-3 cm long finger-like projection on the distal margin, adaxially glabrous, abaxially sparsely and minutely pilose, and with a narrow marginal strip of brown scales, mostly along the distal margin, without spinules or spines; basal pinnae 12-18 x 0.5-4 cm; middle pinnae 42-52 x 4 cm; apical pinnae 5-7 ribbed, 45-47 cm long, 9-11 cm wide, occupying 15.4 cm along rachis. Inflorescences 90-123 cm long, interfoliar or infrafoliar when old; prophyll 35 cm long, 1.5 cm wide; peduncular bract (only a fragment seen) apparently thin and fibrous; peduncle 68-90 cm long, 5-6 mm wide at apex, compressed, covered with brown scales and minute spinules, unarmed or with a few scattered, brown or yellow spines to 1 cm long; rachis 21-24 cm long, with minute brown spinules; rachillae 8-12, evenly spaced 3-4 cm apart along the rachis, covered with minute brown spinules like those of the rachis, with brown scales mainly on the abaxial surface, only the pistillate portion seen; basal rachillae 25-32 cm long in the proximal, triad-bearing portion, without flowers for 1.5-2.5 cm, triads loosely arranged toward base, progressively closer above, most densely arranged near the middle; apical rachillae with pistillate flowers for ca. 6-7 cm; triads sunken into pits in the rachillae. Staminate flowers not seen. Pistillate flowers 3.5 mm long; sepals broadly ovate, 1.8 mm long, glabrous; petals 3 mm long, connate for 1/2 their length, the lobes ovate, acute or rounded at apex, adaxially glabrous, abaxially with a few minute, scattered spinules; staminodial ring 2.1 mm long, inconspicuously toothed, adnate to petals; pistil ca. 2 mm long, glabrous; fruits not seen.
Distribution. Known from only two collections made at the bay of Buenaventura, on the Pacific coast of Colombia, near sea level.
Conservation status. Aiphanes buenaventurae has been collected only twice in 84 years, in spite of the fact that extensive collections have been made in the Buenaventura area over this period. Since forest cover in the region has changed dramatically, this species must be considered as Critically Endangered, according to IUCN parameters (IUCN 2001), following criteria A2c -an estimated reduction of population size in more than 80% in the last three generations, due to causes that are still operating and have caused a reduction in its area of occupancy.
Paratype. COLOMBIA. Valle del Cauca: Agua Dulce, an island in Buenaventura Bay, 12 Feb 1967 (fl), H. E. Moore et al. 9470 (BH!).
In our treatment of Aiphanes erinacea we discussed a geographically isolated specimen (Moore et al. 9470) resembling Aiphanes erinacea but with longer, more narrowly cuneate pinnae, inflorescences with few rachillae inserted at long intervals along a short rachis, and spiny pollen. We indicated that future studies would reveal whether it represented a different species or a wider circumscription of A. erinacea. The study of an old collection not available to us during our revision, as well as a better understanding of the morphological variation and narrow endemism in the genus, has led us to conclude that this entity represents a distinct species. Differences between Aiphanes erinacea and Aiphanes buenaventurae are shown in table 1.

Distribution. Western slopes of the Andes in southern Colombia (Valle and Cauca) and northern Ecuador (Carchi). There is an area in between, in the department of Nariño, Colombia, where the species has not been found. It may have been overlooked or mistaken for A. gelatinosa, but its occurrence in this area is likely.
Conservation status. At present Aiphanes multiplex is not threatened, due to the extense forest cover of the areas where it grows. It is furthermore protected in the Muchique National Park, in Colombia.
In our treatment of Aiphanes gelatinosa (Borchsenius & Bernal 1996), we recognized two morphological forms, which we thought might represent different taxa. Plants from the type locality have caespitose stems, linear, weakly plicate pinnae, single inflorescences, and spiny pollen, whereas plants from two different localities north and south of the type locality have solitary stems, narrowly cuneate, strongly plicate pinnae, multiple inflorescences and pollen without spines. The latter form was informally called by us 'triplex.' The lack of further evidence, however, made us refrain from giving this form any taxonomic status. Given our current undertanding of intra- and interspecific variation in the genus, however, we recognize that this was clearly a mistake. Preliminary molecular evidence (Borchsenius et al. unpublished data) also indicate that typical A. gelatinosa and the form called 'triplex' by us belong to different clades. As a new collection from Munchique National Park has four inflorescences per node, we have preferred the name multiplex instead of the misleading triplex. Differences between the two species are shown in table 2.
Aiphanes killipii (Burret) Burret vs. Aiphanes horrida (Jacq.) Burret
Burret (1932a) described Martinezia killipii based on a collection made by E. P. Killip in the department of Santander, Colombia, in 1927. A few months later, in his synopsis of Aiphanes (Burret 1932b), he transferred the species to this genus. Burret considered Aiphanes killipii to be closely related to A. horrida (as A. caryotifolia), from which he separated it on account of the spinulose fruits, the abundant yellowish spinules on the infructescence, the rachillae not curved at the insertion of each staminate flower, the larger fruits and fruiting perianth, and the pinnae more abruptly and strongly broadened.
Based on the only collection available at the time of our study, the type specimen without a field description, we included A. killipii in synonymy under A. horrida (as A. aculeata). However, a recent re-collection of Aiphanes killipii from Santander, ca. 116 km S of the type locality, shows that the type was not just a deviating individual of A. horrida, but represents a population with constant morphological characteristics and spanning a substantial geographic area. The conclusion is that Burret's taxon should be treated as a separate species, differing from A. horrida in a number of morphological characters (Table 3).
Martinezia killipii Burret, Notizbl. Bot. Gart. Berlin-Dahlem 11: 326. 1932. Type. COLOMBIA, Santander, Río Suratá valley, between Bucaramanga and El Jaboncillo, 800-1500 m, 2 Jan 1927, Killip & Smith 16362 (holotype, B, destroyed; isotypes, A, BH, GH, US).
Stem solitary, 2.5-4 m tall, 4.5-5 cm diameter, with black spines to 10 cm long.

Distribution. Currently known from only one locality on the Eastern Cordillera in Colombia, ca. 116 km S of the type locality. At this area, A. killipii grows in very narrow forest remnants along a creek, surrounded by pastures. The species was not found at its type locality during a search for it in 1987.
Specimen examined. COLOMBIA: Santander, Mun. Suaita, corregimiento de San José de Suaita, carretera a Guadalupe, 500 m de San José, 6º 9´ N, 73º 21´ W, 1400 m, 29 Sep 2003, Bernal 3433 (COL).
Conservation status. Aiphanes killipii must be considered as Critically Endangered, according with the parameters of IUCN (IUCN 2001), following criteria A2c --an estimated reduction of population size in more than 80% in the last three generations, due to causes that are still operating and have caused a reduction in its area of occupancy.
Aiphanes lindeniana (H. Wendl.) H. Wendl., Aiphanes concinna H.E. Moore, and Aiphanes stergiosii M. Niño, Dorr & F.W. Stauffer
Aiphanes lindeniana was described by Wendland (1857) as Martinezia lindeniana, based on a specimen collected by Funk & Schlim in Florida, Sandander, in northeastern Colombia, at 1800 m of elevation. Our interpretation of this name (Borchsenius & Bernal 1996) was based on the rather incomplete lectotype at LE, and on an incomplete topotypic collection made in 1987, and we concluded that it was the same entity as the one described from the mountains of Cundinamarca as Aiphanes concinna H.E. Moore. We, therefore, placed the latter in synonymy of A. lindeniana.
In 2004, one of us (RB) made new and complete collections of Aiphanes lindeniana at the original locality. About the same time, a new species, Aiphanes stergiosii, based on plants similar to these, was proposed by Niño et al. (2005) from the Andes of Venezuela. Comparison of an isotype collection of A. stergiosii in US and the recent topotypic collections of A. lindeniana, lead to the unambiguous conclusion that these represent a single species, the one described by Wendland as A. lindeniana, and that this species differs from A. concinna in a number of characters. Aiphanes lindeniana is a solitary palm with polystichous leaves that have 18-31 narrowly cuneate pinnae per side, these with the margins usually spineless; A. concinna is cespitose, with distichous leaves that have 32-45 linear to lanceolate pinnae per side, the pinna margins densely spiny. We therefore, reinstate A. concinna as a distinct taxon, and place A. stergiosii in synonymy of A. lindeniana.

Distribution. Southern slopes of the Andes in western Venezuela (Portuguesa), Eastern Cordillera of Colombia in Santander, and Central Cordillera of Colombia in Antioquia, just across the Magdalena valley from Santander. Grows in cloud forest at 1600-2000 m. Probably grows also in the intervening areas of Norte de Santander (Colombia) and Mérida (Venezuela).
Conservation status. Aiphanes lindeniana must be considered as Endangered, according to IUCN parameters (IUCN 2001), following criteria B1abiii (restricted distribution represented by very few localities and habitat in continued deforestation).
Specimens examined. COLOMBIA. Antioquia: Santa Rita, 5 km E of Guatape, 2000 m, 17 Sep 1987 (fl), Bernal & Tobón 1375 (AAU, COL); Santander: Mun.

The type locality of Aiphanes lindeniana has been cited (Borchsenius & Bernal 1996) as Pamplona, in Norte de Santander. However, this is a mistake, as Wendland states in the protologue that the plant was collected -in the forests at Florida-, which is on the western slopes of the Cordillera Oriental in Santander. The present departments of Santander and Norte de Santander were referred to in the 19th century as Provincia de Pamplona.
Niño et al. (2005) distinguished A. stergiosii from A. lindeniana by a less robust habit, and the presence of fewer and shorter spines. They also noted that A. lindeniana tends to be a clustered palm whereas A. stergiosii was solitary. As key characters they mentioned differences in the indument of the leaf axis and pinnae, as well as the presence in A lindeniana of small spines lining the pinna margins and major veins. The differences were, however, established through comparison with specimens of A. concinna from the central part of the Cordillera Oriental in Colombia (Cundinamarca, Huila) and not with specimens of the true A. lindeniana described by Wendland from Northern Colombia. The latter populations correspond in all aspects to A. stergiosii. It may also be added that indument and spine characters are notoriously labile in species of Aiphanes (Borchsenius & Bernal 1996), so minor differences in these characters observed in a small number of specimens should be interpreted with caution.
The specimens cited above include all collections of A. lindeniana that we have seen. Two were cited by Borchsenius and Bernal (1996): Bernal & Tobón 1375 and Bernal & Galeano 1352. All other specimens cited under A. lindeniana in the monograph are A. concinna.

An epitype for Aiphanes simplex Burret
Aiphanes simplex was described by Burret (1932) based on a specimen collected by W. Kalbreyer in Antioquia, Colombia. There are many collections of this species, and it is well defined and clearly understood. The type specimen was kept at B, where it was destroyed in World War II, except for a single staminate flower (Borchsenius & Bernal 1996), which scarcely serves any taxonomic purpose. After our monograph was submitted, the concept of epitype was introduced at the Tokyo Code (Greuter et al. 1994), and therefore we here designate an epitype for this species.
