A colorful new species of Neooreophilus (Orchidaceae: Pleurothallidinae) from the eastern Andes of Colombia and Ecuador

A colorful new species of Neooreophilus (Orchidaceae: Pleurothallidinae) from the eastern Andes of Colombia and Ecuador

The new species described below was discovered independently about 10 years apart in two widely separated locations: the Cordillera Abitagua in the east-central Andes of Ecuador, and the Sibundoy Valley in the southeastern Andes of Colombia, ca. 300 km away. On morphological grounds it appears to be most closely related to Neooreophilus werneri (Luer) Archila and N. cordilabius (Luer) Archila from the Andes of southeastern Ecuador, and N. chelosepalus (Luer & Hirtz) Archila, which is thought to have been collected in the Andes of western Ecuador.

Dracula irmelinae, a new species in the subtribe Pleurothallidinae (Orchidaceae) from the Western Andes of Colombia

Dracula irmelinae, a new species in the subtribe Pleurothallidinae (Orchidaceae) from the Western Andes of Colombia

present in ex situ cultivation. Finally, the two species have unambiguously distinct geographic distributions. D. irmelinae occurs ~200 km further north from D. verticulosa, in a different cordillera (see below). The populations of the two species are separated by the Cauca river valley (~600–900 m), which acts as a geographic barrier that creates reproductive isolation between the two taxa. To date D. verticulosa has not been reported in the Western Cordillera of Colombia. Although overall D. irmelinae is phenotypically most similar to D. verticulosa from the Central Cordillera, when only species of the Western Cordillera are compared, the phenotypically most similar species from the Western cordillera is D. gigas Luer (Luer). The later taxon differs from D. irmelinae in that it lacks any significant pubescence or maculate pigmentation in the sepals (vs. densely pubescent sepals), has narrower leaves (vs. broader leaf blades), and thinner, typically erect inflorescences (vs. lateral to usually descending) that do not produce as many flowers per inflorescence. Table 1 compares floral traits and geographic distributions of D. gigas, D. x aphrodes Luer & Escobar, D. dalströemii Luer, D. x hawleyi Luer, and D. trinympharum Luer with D. irmelinae. Within the genus Dracula, these species share some phenotypic similarity with the new taxon described here.

Telipogon mayoi (Orchidaceae), a new species from Western Andes of Colombia

Telipogon mayoi (Orchidaceae), a new species from Western Andes of Colombia

Introduction. Telipogon Kunth is a neotropical orchid genus, which currently contains around 260 accepted species (Martel unpublished data). Species of this ge- nus can be found from southern Mexico to Central America, the Caribbean and in the Andes, from Ven- ezuela to northern Bolivia between 500 and 3600 m (Martel & Nauray 2013, Collantes & Martel 2015). Telipogon species are usually associated as having col- orful and showy flowers (see Dodson & Escobar 1987, Dodson 2004). However, some Telipogon species pos- sess very small and non-showy flowers; those species were formerly included in the genus Stellilabium. The genus Stellilabium was transferred to Telipogon based on molecular data (Williams et al. 2005). Recently, Martel et al. (2017) proposed to use the term “min- iature Telipogon” to distinguish the Telipogon species that fit with the characteristics of the former Stellilabi- um. Thus, miniature Telipogon are characterized as be-

A New Subhaplogroup of Native American Y Chromosomes from the Andes

A New Subhaplogroup of Native American Y Chromosomes from the Andes

We surveyed sequence variation in 15 Y-chromosomal loci (M19, M25, M120, M143, M194, M199, M323, M346, M378, MEH2, N14, P106, P292, P48, and P89) after amplification using the primers and conditions in Kara- fet et al. (2008). Although these loci carry known SNPs in Native Americans (see Fig. 1), they have not been thoroughly screened by sequencing in South American individuals (Karafet et al., 2008). Except the SNP M19 that is present in Ticuna and Wayuu Indians (Bortolini et al., 2003), and SNPs at MEH2 and M346 that seem to be present in most of Native American haplogroup Q chromosomes (see Fig. 1), all other known SNPs were absent or very rare in South America (this study and unpublished data). All fragments were sequenced in 12 selected individuals (8 Q1a3a and 4 Q1a3*; selection cri- teria below) to identify new SNPs as well as to screen for variation at known SNPs. The PCR products were ei- ther purified following Exonuclease I and Alkaline Phos- phatase (Amersham Biosciences) treatment or PEG/NaCl precipitation. Both DNA strands were sequenced using a MegaBACE 1000 sequencer (GE Healthcare) or ABI3130xl Genetic Analyzer (Applied Biosystems). High quality sequences were aligned and checked for quality and accuracy using the Phred, Phrap, and Consed pro- grams (http://www.genome.washington.edu) to visualize and check manually all chromatograms for the presence of new polymorphisms. Whenever a putative polymor- phism was identified, the sample was re-amplified and resequenced for confirmation.

Species of Ancistrus (Siluriformes, Loricariidae) from Ecuador, with the description of a new species from the Amazon River Basin

Species of Ancistrus (Siluriformes, Loricariidae) from Ecuador, with the description of a new species from the Amazon River Basin

During the analysis performed some figures and original descriptions of species caught our attention. Eigenmann & Eigenmann (1889) designate the variety Ancistrus cirrhosus dubius, usually accepted as Ancistrus dubius, whose specimens come from two localities in Brazil, Gurupá and Tabatinga. Gurupá is located at Pará state, near Marajó Island, very distant from Andes, the other Tabatinga is closer, but may be with a limited influence of Andean rivers characteristics. The original description is limited to few characters indicated in the key included. According to the key A. dubius has the caudal fin lunate, dorsal fin I,7 vs. I,8 in A. cirrhosus, and color pattern consisting of: Body dark brown and back with two darker cross-bands; head irregularly marbled. At the ACSI images database a photo of paratype, MCZ 7983 is found (Morris, et al. 2006). Specimen is a juvenile female (70 mm SL) without color, but on belly dissipated (vanished) white dots can be observed. The available photo at ACSI seems to be similar to A. malacops, pectoral-fin “spine” looks elongated, unfortunately caudal-fin is damaged and avoid appropriate compare, but Eigenmann & Eigenmann (1889) explicitly indicated a lunate caudal fin. The caudal fin lunate is present in A. alga, but the color pattern reported is very different. According the few morphological characters and distance between the localities it seems appropriate indicate that A. dubius is a different species to those reported in this work. However, comparisons with newly captured specimens are need to establish the taxonomic status of A. dubius.

New species of Trigona and cleptobiotic Lestrimelitta from French Guiana (Hymenoptera: Apidae)

New species of Trigona and cleptobiotic Lestrimelitta from French Guiana (Hymenoptera: Apidae)

Diagnostic characters: Larger than sympatric L. limao. which near Kourou lacks the ferruginous malar arca and stiff, black hairs on the scutellum and margins of the metasomal terga; specimens of limllO from Sao Paulo , Brasil, Kourou, French Guiana, and Barro Colorado Island, Panamá lacked the uniform covering of stiff, black hairs on the median tibia; limao also possesses five hamuli on the hind wing, rather than six; an identification of L. guyanensis was made in error by Roubik ( 1 979b), based on a description provided by Schwarz ( 1 948) of L. limao, which did not fit the specimens collected at a nest in French Guiana (see Roubik, 1 979b); Lestrimelitta is reported to vary substantially and possibly contains several sibling species, or distinct subspecies of limaD (l . Camargo, personal communication); a male paratype of L. limao rufipes Friese from Sao Paulo , Brasil, proved identical to L. limao eollected from a nest in French Guiana and also to the iIIustrations given by Schwarz ( I 948) of L. limao from Sao Paulo, based on the structure of the genitalia .

A new species of Coniophanes (Squamata: Colubridae), from the coast of Michoacán, Mexico

A new species of Coniophanes (Squamata: Colubridae), from the coast of Michoacán, Mexico

Harrison (1992) reported on stomach con- tents of a few Coniophanes piceivittis and C. schmidti. He found that these snakes feed on frogs, lizards and blind snakes. Based on these findings we can assume that C. michoacanen- sis also feeds on reptiles and amphibians. Many frogs and lizards were found at night in tunnels under the highway to Caleta de Campos (for a complete species list reference Vargas-Santamarı´a and Flores-Villela, 2006). Harrison (1992) also reports that pregnant females have no more than four fully yolked eggs at a time; one fully developed egg, ready for deposition, was found in one specimen of C. piceivittis from Oaxaca, collected in December, and a specimen from Veracruz, collected in July; a female C. schmidti from Campeche had four yolked eggs in June. Neonates, with umbilical scars, are found between late July and November and measure between 140 and 175 mm SVL (Harrison, 1992). Coniophanes piceivittis and C. taylori occupy habitats similar to those of C. michoa- canensis, in tropical deciduous forests, al- though they have also been collected in other types of dry forests and in subhumid forests.

Observations on the nests of Costa Rican Halictus with taxonomic notes on Neotropical species (Hymenoptera: Halictidae)

Observations on the nests of Costa Rican Halictus with taxonomic notes on Neotropical species (Hymenoptera: Halictidae)

The sympatric species H. hesperus and lutescens agree in the more densely punctate mesoscutum with punctures separated by less than a puncture width. They also agree with one another, and differ from nearctic species, in having an apical filament on the male gonostylus. The metasomal terga of the male are not constricted basally nor are the tergal margins depressed. The sixth metasomal sternum of the male has a weak longitudinal depression and the posterior margins of the fourth and fifth are slightly concave in both species. The two species differ from one another as indicated in Table 1 and Figs. 7 to 10. The known localities for each are shown in Figs. 1 1 to 12. Both occur from sea leve! to at least 1260 m, occurring together at that altitude 8 miles southeast of Tehuitzingo, Puebla, Mexico. The two species also occur together

A new species of Vanilla (Orchidaceae) from the Colombian Pacific region

A new species of Vanilla (Orchidaceae) from the Colombian Pacific region

Vanilla rivasii Molineros-Hurtado, González, Flanagan & Otero belongs within Vanilla subgenus Xanata. Vanilla rivasii has affinity to the V. hostmannii group, possessing the thickened veins in the lip apex and the distichous arrangement of the basal bracts of the inflorescence characteristic of this group. Vanilla rivasii may be distinguished from the other Vanilla species in the group by the frequent terminal position of the inflorescence, although occasionally this can be lateral. The bracts of the inflorescence are smaller than those of related species such as V. cribbiana Soto-Arenas, V. ruiziana Klotzsch, and the sympatric V. dressleri Soto-Arenas. Flowers are larger, with deeply recurved sepals. The lateral sepals are fused in the basal third. The mid-lobe of the labellum is F iGure 2. Vanilla rivasii, photograph of the flower in situ.

A new species of Asplenium L. (Filicales: Aspleniaceae) from the neotropics.

A new species of Asplenium L. (Filicales: Aspleniaceae) from the neotropics.

Asplenium L. is characterized by usually clathrate rhizome scales, stipes containing two vascular bundles basally that are fused in “x” form distally and sori elongate to linear with indusium (Moran, 2011). Asplenium is different from the similar genus Diplazium Sw. by 20-28 (vs. 15-20) cells in the annulus of sporangia, one (vs. 2 or 3) rows of cells in the stalk of the sporangium and vascular bundles in X-shaped (vs. two separate and elliptic strands) in the distal part of the stipe (Moran, 2011).

(Orchidaceae), a new species from Central Peru

(Orchidaceae), a new species from Central Peru

Materials and methods. The plant material was collected in Curimarca, Molinos District, Jauja Province, Junín Department (Fig. 1) in fieldwork in which the flora associated with the high Andean forests of Polylepis was evaluated. Photographs were taken in the field and laboratory for preparing and diagramming a Lankester Composite Digital Plate (LCDP). Searches were made in AMODATA, where 691 records were retrieved for Epidendrum from Junín, out of a total of 10,165 for Peru. Other herbaria recorded include AMES, AMO, B (photographs lodged at F), CAS, COL, F, G, GH, HB, HBG, HOXA, K, LE, LL, M, MA, MO, MOL, NY, OXF, P, PR, RENZ, S, SEL, TNS, UC, US, USM and WIS. These records are based on images taken at these herbaria through the years and do not necessarily include recent collections. Records of specimens and illustrations from David E. Bennet Jr. (at MOL and AMO) were also searched. The records for Junín were studied for possible matches. Comparisons were made with E. ampelospathum Hágsater & Dodson (2004) and E. ampelomelanoxeros Hágsater, E.Santiago & E.Parra (2013) (images of type and live material at AMO, as well as descriptions), the species most similar vegetatively to E. curimarcense. In addition, due to the floral and inflorescence details, the species was also compared to Epidendrum totoroense J.S.Moreno, Hágsater, E.Santiago & Erazo (2016). The pressed material was deposited at HOXA and HUT herbaria.
