A new species of Espeletiopsis (Millerieae, Asteraceae) from Colombia.

Project description:A new species of Espeletiopsis was found in two small páramos of Norte de Santander, Colombia. The species is named Espeletiopsis diazii honoring the contributions of Santiago Díaz-Piedrahita in recognition of his vast knowledge of the Compositae in Colombia. This is a very distinctive species, markedly different from most of the Espeletiopsis present in Colombia. The new species is closely related to Espeletiopsis caldasii and Espeletiopsis santanderensis, but differs in having (1-)4-6(-7) capitula, with very short peduncles, and capitula arranged in a compact or densely glomerate cyme. With a total distribution area of less than 75 km(2), this species is probably critically endangered or imperiled.

Notes on the genus <i>Ophryosporus</i> (Asteraceae, Eupatorieae) in Chile.

Project description:Ophryosporus Meyen is reviewed for Chile and an updated species list for the country based on herbarium records and literature review is presented. A key to the Chilean species is provided and a distribution range of taxa is indicated based on herbarium records and our own collections. We include several lectotypifications as well as an epitypification of Ophryosporus hoppii. The presence of two species, O. hoppii and O. floribundus, formerly accepted for Chile, is questioned and their actual distribution discussed.

A refined concept of the Critoniopsisbogotana species group in Colombia with two new species (Vernonieae, Asteraceae).

Project description:Critoniopsisbogotana is more precisely delimited, and two related Colombian species are described as new. The form of trichomes on the abaxial surfaces of the leaves is found to be of major importance. A short key to the Critoniopsisbogotana group is provided.

<i>Espeletia praesidentis</i>, a new species of Espeletiinae (Millerieae, Asteraceae) from northeastern Colombia.

Project description:A new species of Espeletia from the Páramo de Presidente in northeastern Colombia is described. The species is named Espeletia praesidentis after the name of the páramo, and it is dedicated to the President Juan Manuel Santos, for his persistent efforts in working for peace for Colombia. The new species is closely related to Espeletia dugandii, but differs in the shape and colour of the leaves and arrangements of the capitulescences. A large population was found, but its total extension is yet to be determine.

Two new Marquesan species of the southeastern Polynesian genus Oparanthus (Asteraceae, Coreopsidinae).

Project description:Two new species of the recently revised genus Oparanthus (Asteraceae, Subtribe Coreopsidinae) were discovered during the National Tropical Botanical Garden/Smithsonian Institution 1997 expedition to the Marquesas Islands. Oparanthus woodii W. L. Wagner & Lorence, sp. nov. is known from a single population on the island of Nuku Hiva, and Oparanthus tiva W. L. Wagner & Lorence, sp. nov. is known only from Tahuata. Small domatia with a tuft of hairs occur in Oparanthus tiva (and the previously known Oparanthus hivoanus), and similar but naked domatia are found occasionally in Oparanthus woodii. Domatia are of exceedingly rare occurrence in Asteraceae. Both new species are extremely rare and are considered critically endangered (CR) as are the other four species of the genus.

Three new species of the genus Ripipteryx from Colombia (Orthoptera, Ripipterygidae).

Project description:Three new species of Ripipteryx Newman (Orthoptera: Tridactyloidea: Ripipterygidae) are described from Colombia; namely Ripipteryxdiegoi sp. n. (Forceps Group) and Ripipteryxguacharoensis sp. n. (Marginipennis Group) from Parque Nacional Natural Cueva de los Guacharos in Huila, and Ripipteryxgorgonaensis sp. n. (Crassicornis Group) from Parque Nacional Natural Gorgona in Cauca. Ripipteryxdiegoi sp. n. is characterized by the antennae black with white spots on flagellomeres 3-7, male subgenital plate with median ridge forming a bilobed setose process, epiproct produced laterally near its base and phallic complex with virga thickened distally and not reaching beyond the membrane. Ripipteryxguacharoensis sp. n. is characterized by the antennae thick with white spots present dorsally on flagellomeres 1-4 and 8, epiproct narrow and triangular, uncus reduced and lacking a distal hook, phallic complex with a concave ventral plate and a dorsal elevation in the middle extended to the virga, and the virga itself with two small projections basally. Ripipteryxgorgonaensis sp. n. is characterized by the epiproct with a lateral notch, antennae with a white dorsal spot on flagellomere 1 and flagellomeres 4-7 entirely white. The antennal color pattern of Ripipteryxgorgonaensis sp. n. strongly resembles that of Ripipteryxatra but differs from the latter in the absence of any significant morphological modification of the flagellomeres.

Dysaster cajamarcensis, a new shrubby genus and species of Astereae (Asteraceae) from Peru.

Project description:Dysaster cajamarcensis is a spreading broad-leaved shrub named as a new genus and species of the tribe Astereae subtribe Hinterhuberinae collected in northern Peru. It has bisexual disc florets, disc style branches with strong stigmatic lines and hairy appendages, compressed achenes in both ray and disc florets, and papyraceous involucral bracts.

The first Paratropididae (Araneae, Mygalomorphae) from Colombia: new genus, species and records.

Project description:The family of mygalomorph spiders Paratropididae Simon, 1889 is here reported for the first time for Colombia, where it is represented by three genera (Anisaspis, Paratropis, Stormtropis gen. n.) and eight species. One genus, Stormtropis, and six species constitute new taxa that are here diagnosed, described and illustrated. The geographical distribution of Paratropispapilligera FO Pickard-Cambridge, 1896 and Paratropiselicioi Dupérré, 2015 are also redescribed and expanded on the basis of new material examined. The diagnosis of the subfamily Paratropidinae, Paratropis Simon, 1889 and Anisaspis Simon, 1892 are emended including the variations of the new species. Likewise, a geographic distribution map for the entire family and a taxonomic key for the males of Paratropidinae are included. Other biogeographic, morphological, and taxonomic aspects are discussed.

Taxonomic notes on Cyperaceae of Nepal: new records of a genus, six species and other noteworthy species.

Project description:This paper reports on the presence of one generic and six specific new records of Cyperaceous species for the flora of Nepal. Amongst the new discoveries are the genus Machaerina, alongside species: Eleocharisochrostachys, Fimbristylisacuminata, F.ferruginea, F.nutans, F.thomsonii and Scleriarugosa. The taxonomy and distribution of Actinoscirpusgrossus, Fimbristylissalbundia and Fuirenaumbellata in Nepal are clarified through notes on nomenclature, description, distribution, specimen examination, identification keys and photographs.

Project description:Mangatangi parvum gen. n. and sp. and Forsteropsalis pureroa sp. n. are described from the North Island of New Zealand. Pantopsalis listeri (White 1849) and Pantopsalis cheliferoides (Colenso 1882) are redescribed and no longer regarded as nomina dubia; Pantopsalis luna (Forster 1944) is identified as a junior synonym of Pantopsalis listeri. A key to Pantopsalis species is provided.
