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.

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.

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.

Andeogryllus n. gen. including two new species from the inter-Andean slopes and valleys of the Magdalena and Cauca rivers of Colombia are described. This new genus is similar to Zebragryllus in their habitus, differed by not have white stripes on the body or antennae and by a modified pseudoepiphallic sclerite. The genus Atsigryllus (Atsigryllae group) is located in the subtribe Anurogryllina, highlighting the secondary reduction of the median lobe. An updated key is provided for the genera of the subtribe Anurogryllina and the species of the new genus.

Middle Pair

Isosoma Allynii, n. s.Female.—Average length .10 of an inch. Color of body and antennæ uniform black, the first with a slight greenish lustre. Head about .025 of an inch wide, about two thirds as long; the antennæ a little enlarged at the ends, hairy, microscopic hairs moderately scattered over the head and thorax. Thorax, as well as head, punctured; wings hyaline, dotted over with microscopic hairs, the thorax in its widest part about the width of the head. Abdomen gradually tapering from near the base, the ovipositor slightly exserted. The color of the legs vary slightly; in five specimens the anterior and posterior legs have the femurs fuscous except at the ends; the tibiæ with basal half fuscous, the rest yellow; the terminal joint of tarsi fuscous, the rest yellow; the middle pair of legs are yellow throughout except the terminal tarsi. Two specimens have all the femurs fuscous, yellow at the ends. One specimen has all the femurs pale red, and the tibiæ fuscous, but this is probably a change from yellow by the poison bottle used in killing. One is marked like the first five, with the yellow replaced by pale red; another is like the first five, except that the middle tibiæ are a little clouded at base.

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.

The identification of Eumastacidae is normally based on the study of phallic complex. However, the genus Zeromastax possesses additional characters that easily differentiate it from other eumastacids. These are ten antenomeres, spines located ventrally on the posterior femur, spur in the distal part of hind tibiae, micropterous condition and the phallic complex with subepiphallic sclerite. Two new species are described, Z. aris and Z. malavasei from the Andean region of Colombia, which show differences in external anatomy including the pronotum, shape of tegmina and coloration pattern, as well as several differences in the phallic complex.

We describe two new species of Ranitomeya (family Dendrobatidae), R. yavaricola sp. nov. and R. cyanovittata sp. nov., from Peru. Ranitomeya yavaricola sp. nov. is morphologically similar to certain other species of Ranitomeya (in particular R. flavovittata), but the new species can be easily distinguished from all other species of Ranitomeya based on its unique limb coloration: solid bronze without black markings. Despite having searched in numerous localities throughout this region, we have found the new species at only a single locality near the confluence of the Yavarí and Yavari-Mirin rivers. Based on acoustic and molecular data, the new species is a member of the vanzolinii group, and is sister to the second new species, R. cyanovittata. Ranitomeya cyanovittata sp. nov. is only known from a single locality in the Sierra del Divisor in Amazonian Peru. This species can be easily distinguished from the other species of Ranitomeya by a unique coloration pattern that consists of just two colors: black background with blue lines or reticulations.

Literature about Mesitiinae Kieffer, 1914 has not been treated extensively from a taxonomic viewpoint in comparison with other subfamilies in Bethylidae Latreille, 1802. Our research on species of Metrionotus Móczár, 1970, Clytrovorus Nagy, 1972 and Sulcomesitius Móczár, 1970 revealed a new hypopygium shape pattern, namely a ‘star-shaped’ hypopygium, which is characteristic of a new genus, Astromesitius gen. nov., with two new species Astromesitius thionyi gen. et sp. nov. and Astromesitius olavoi gen. et sp. nov. The descriptions of both new species are based on male specimens collected in Thailand and the United Arab Emirates. Astromesitius quatei (Móczár, 1977) gen. et comb. nov. is designated as type species for the new genus, which is erected for a total of seven species. The main diagnostic characteristics are the head longer than wide; a clypeus with a median lobe quadrate; an antenna with distinct long setae, with pedicel caliciform, and with flagellomeres long and caliciform; pronotum and anteromesoscutum with longitudinal sulcus indistinct or absent; metapectal-propodeal complex with posterior projection hardly distinct or absent; hypopygium star-shaped; genitalia with aedeagus slender and fusiform.
