Subjective Synonym

The old genus Libitia Simon, 1879 of small Andean harvestmen is revisited. The monotypic genus Libitiella Roewer, 1947 is herein considered a junior subjective synonym of Libitia. Accordingly, Libitiella bipunctata (Sørensen, 1932) is restored to the combination Libitia bipunctata. The species Libitia cordata and Libitia bipunctata comb. nov. are redescribed and the new species Libitia gandalf sp. nov. and Libitia iguaque sp. nov. are herein described from Cordillera Oriental of Colombian Andes (Chingaza Natural Park and Iguaque Natural Park, respectively). The species Gonyleptes multimaculatus Wood 1869, currently under the synonymy of L. cordata, is revalidated and transferred to Paecilaemella Roewer, 1925 forming Paecilaemella multimaculata comb. nov., and the species Cynorta itacoaiensis H. Soares, 1970 is herein considered a junior subjective synonym of it. In addition, the second current species of the genus, Libitia fusca (Simon, 1879), is transferred to Metalibitia. Libitia is diagnosed based in genital and external morphology, an identification key of the four species and distribution maps are offered.

Two new species of Hemiosus (Coleoptera: Hydrophilidae) from the central cordillera of the Colombian Andes are described. Hemiosus molanoi González-Rodríguez & García-Hernández sp. nov. and H. quindiensis González-Rodríguez & Clarkson sp. nov. are described based in 56 adult specimens collected in river-associated sandy puddles (26 specimens of H. molanoi sp. nov.) and temporary puddles near crops (26 specimens of H. quindiensis sp. nov.). Both species are identified mainly by characteristics of the aedeagus: Hemiosus molanoi sp. nov. has subtriangular parameres, median lobe shorter than parameres and longer than appendices which are acuminate and phallobase shorter than parameres, strongly asymmetrical in basal two-fifths; H. quindiensis sp. nov. has parameres gradually tapering towards rounded apices, median lobe shorter than parameres and longer than appendices which are acuminate and phallobase shorter than parameres, strongly asymmetrical in basal half. Dorsal coloration pattern, overall shape of the meso- and metaventral process and abdominal ventrites are also informative to distinguish the new species from remaining described Hemiosus. Diagnoses, illustrations and habitat characteristics are provided.

Two New Species

Two new species of Phialocephala were isolated from the periderm of living branches of forest trees in Germany. In culture, Phialocephala compacta Kowalski & Kehr sp.nov., found on Alnus, is characterized by crowded conidiogenous heads that become deeply pigmented with age. Phialocephala scopiformis Kowalski & Kehr sp.nov., isolated from Picea and other conifers, develops elongated, complex conidiogenous heads with up to 15 series of branches in culture. The taxonomic placement of both new species and their role in endophytism and in natural pruning of branches is discussed. Key words: Picea abies, Alnus glutinosa, Phialocephala compacta, Phialocephala scopiformis, branch pruning fungi.

Central Cordillera

Frequent biodiversity sampling and monitoring programs often lead to relevant taxonomic findings. Here, as a product of different field expeditions to two places in the northern Andes, we discover and describe two new species of rain frogs of the genus Pristimantis from the cloud forests of the Central Cordillera of Colombia. Pristimantis chocolatebari sp. nov. is diagnosed by having the following character states: dentigerous process of vomer triangular, snout large and protruding, dorsum smooth, vocal slits and vocal sac present, groin and hidden part of the thighs yellow. Pristimantis carylae sp. nov. is diagnosed by having iris copper red, dentigerous process of vomer oval, snout short and rounded, dorsum finely shagreen with scattered tubercles, double nuptial pad in males, groin and hidden part of thighs pink. We also infer, for the first time, the phylogenetic position of P. permixtus, P. platychilus, and two candidate new species. In addition, we emphasize not to use genetic distance as the only source of evidence for species delimitation, considering the high intraspecific diversity found in one of the species described here. Finally, we highlight the relevance of different habitat and ecosystem conservation strategies to promote amphibian diversity studies in the Andes.

Two New Species

We describe two new species of the genus Pristimantis from the western margin of the Eastern Cordillera of Colombia. The species have a sympatric distribution and are found in the humid tropical forests of the lower part of the Tamá National Natural Park (PNN Tamá) and its buffer zone. The new species were described from morphological comparisons and phylogenetic reconstruction from the sequencing of three mitochondrial and two nuclear genes. With these two new species, the number of Pristimantis species known in the department of Norte de Santander has increased to 10. In addition, we included new sequences for the species P. anolirex, P. nicefori, P. mondolfii, and P. yukpa. Our explorations in the last decade indicate that there are probably between five and 10 species that have not been described in the northeastern part of Colombia, especially in areas where the armed conflict has predominated in the last five decades.

Two New Species

Two new species from northeastern Somalia, Dicoma paivae and Dicoma cinerea (Asteraceae), both of section Psilocoma Harv., are described. Dicoma paivae is most similar to Dicoma cana Balf. f. of Socotra Island, from which it can be distinguished by its wider, twisted branches, larger, aristate, conduplicate leaves, smaller capitula, and straw-coloured, coriaceus inner phyllaries. Dicoma cinerea is very closely related to Dicoma schimperi (DC.) O. Hoffm. of northeast tropical Africa and the Arabian Peninsula, from which it can be distinguished by the dense whitish tomentum covering the whole plant and by its broadly ovate to almost orbicular leaves with margins bearing bulbous teeth. Key words: Asteraceae, Dicoma, new species, tropical Africa, Somalia.

Two New Species

Two new species, Passiflora splendida and P. quinonesiae of the section Colombiana from the Andes of Cundinamarca Department (Colombia Eastern Cordillera) are described and illustrated. Passiflora splendida is morphologically similar to P. cremastantha of the series Leptomischae, but can be distinguished by its linear stipules, petioles up to 1.8 cm long, lance-ovate leaves (6–8.5 × 2.5–3.3 cm), flowers with a diameter of 9–11 cm long, sepals and petals with intermediate disposition, both longer than the floral tube, floral tube of 3.2–4.5 cm long and fusiform ovary. Passiflora quinonesiae is similar to the species of series Colombianae, most closely related to P. cuatrecasasii and P. lanata. It differs from P. cuatrecasasii by its terete stem, size of the leaves 4.4–15 × 10.3 cm, elliptic bracts and floral tube 5.2–6 cm long. It differs from P. lanata by its ovate leaves, bracts halfway down the floral tube, elliptical sepals and petals, and elliptical ovary. In addition, a taxonomic key to section Colombiana ser. Colombianae and Leptomischae for Colombia is included and information about the ecology, distribution, and conservation status of P. splendida and P. quinonesiae are discussed.

Abstract We describe the new liverwort species Lejeunea ryszardii from montane rainforest in the Central Cordillera of Colombia (Dept. Quindío) and Rectolejeunea halinae from submontane rainforest in the Western Cordillera (Dept. Risaralda). Both species stand out by copious vegetative reproduction via caducous leaves. Lejeunea ryszardii resembles the Caribbean L. paucidentata in the leaf lobes with toothed margins and a narrow base but strikingly differs from the latter species in: 1) leaf margins with mamillose cells, which are sometimes crowned by a small papilla, and with scattered rhizoids with or without a tooth-like base; 2) lobules with narrowly elongate, curved, sharp tooth; 3) stem epidermis brownish and somewhat thick-walled; 4) copious production of caducous leaf lobes. Moreover, L. ryszardii is dark green to brown in color and probably dioicous while L. paucidentata is light green and autoicous. Rectolejeunea halinae resembles the neotropical R. flagelliformis in having ciliate caducous leaves but clearly differs from the latter in the pointed leaf tips, the presence of ocelli in underleaves, and the flagelliform shoots with flat, entire-margined underleaves. The discovery of these new species adds two further endemic taxa to the rich bryophyte flora of the Colombian Andes.
