Shape And Size

Pleurothallis cerea, a species described based on a specimen collected by Lankester in Costa Rica, and commonly placed under the synonymy of Myoxanthus octomeriae or M. congestus, is here recognized as distinct. The species is easily distinguished by the shape and size of the leaf, as well as various floral details, especially of the lip. A new combination, tentatively suggested by Carl Luer but never published, is required and therefore validated. Additionally, the vegetatively striking Myoxanthus affinis is recorded from Costa Rica for the first time based on two recent collections. The species is variable within its broad distribution from Colombia to Bolivia and, although differences with the original material from Peru are evident, we cannot be sure at this time that ours represents a different species. Both species are described and illustrated based on living plants.

AbstractOmiodes Guenée is redescribed based on all New World species, including the type species O. humeralis Guenée. Four new species from Costa Rica, O. janzeni sp. n., O. hallwachsae sp. n., O. sirena sp. n., O. ochracea sp. n., are described. Ten new synonymies are established : Phostria disciiridescens Hampson is =O. croeceiceps (Walker), Phostria cayennalis Schaus is =O. grandis (Druce), Omiodes ochrosoma Felder & Rogenhofer and Phryganodes gazalis Schaus are =O. pandaralis (Walker), Nacoleia lenticurvalis Hampson, Phryganodes anchoritalis Dyar, and Phostria duplicata Kaye are =O. confusalis (Dognin), O. cervinalis Amsel is =O. martvralis (Lederer), Nacoleia indicata ab. pigralis Dognin and Botis fortificalis Möschler are =O. metricalis (Möschler). One new combination is recognized: O. pandaralis (Walker) was transferred from Coelorhynchidia Hampson. A key and an updated checklist to the neotropical Omiodes species is provided, including O. indicata (Fabricius), a worldwide pest. Ten species that do not belong in Omiodes are retained until appropriate generic placements are identified.

A new genus of lichenized fungi of the family Porinaceae is described, known from Costa Rica and Brazil. Flabelloporina Sobreira, M. Cáceres & Lücking is a thus far monospecific genus with an isolated position of its only species in the family, morphologically different from all other genera in Porinaceae. The genus is characterized by the production of numerous, flabelliform squamules on the surface of the thallus, together with black perithecia and transversally septate ascospores (with three septa in the only species). The new combination Flabelloporina squamulifera (Breuss, Lücking & Navarro) Sobreira, M. Cáceres & Lücking is proposed, based on Porina squamulifera Breuss, Lücking & Navarro, and the species is for the first time reported from Brazil.

<p>The molluscan fauna of Isla del Coco has recently been well documented, but the heterobranch sea slugs, traditionally called “opisthobranchs”, remain poorly known. We report 13 new records, increasing the total to 40 species. Of the 13 newly discovered species, the following species had not been previously recorded along the Pacific Costa Rican mainland: <em>Berthella californica </em>(Dall, 1900), <em>Peltodoris rubra</em> (Bergh, 1905), <em>Dendrodoris albobrunnea </em>Allan, 1933, <em>Doriopsilla</em> cf. <em>spaldingi </em>Valdés &amp; Behrens, 1998, <em>Glaucus</em> cf. <em>marginatus</em> (Reinhardt &amp; Bergh, 1864), and <em>Flabellina</em> sp. Additionally, we report <em>Peltodoris rubra</em>, previously known from the Indo-Pacific, for the first time in the Eastern Tropical Pacific.</p><div> </div>

Besleria macropoda, a rare and poorly known gesneriad endemic to Costa Rica, was recently collected for the first time on the southern slopes of the Fila Costeña (Puntarenas Province, SE Costa Rica). The collection considerably widens the geographic distribution to the southeastern part of Costa Rica. Moreover, the following unique characters not previously addressed in the literature were observed and are documented here: (1) The elongate peduncles of the inflorescences are clamped in a channel formed by the sunken midrib of the leaf, rendering the flowers and fruits positioned in the center of the leaf blade. The epiphyllous appearance of the inflorescence on the leaf surface enhances contrasting colors that may aid the pollination and/or fruit dispersal. (2) The fruits split open irregularly, with the fleshy carpel lobes becoming reflexed. This fruit dehiscence deviates from the indehiscent berries that typically characterize Besleria. This results in displaying a globose head of red placental tissue covered by tiny, red seeds. A preliminary survey of Besleria fruits suggests that this peculiar fruit type is present in at least 15 species representing almost 8% of the genus. Fruit morphology of Besleria is therefore less uniform than previously recognized and the “indehiscent berry” can no longer serve as a distinctive generic character of Besleria, which necessitates consideration in floras and identification keys. In addition, a list of herbarium specimens, lectotypification, a distribution map, IUCN red list assessment and an amended key to diagnose Besleria relative to Gasteranthus are provided.

The genus Diadocidia Ruthe is shown for the first time to be present in Costa Rica. Three species were found: Diadocidia nigripalpis Edwards, hitherto known to occur in the south of Brazil, and two new species, hybrida and similis. While nigripalpis is confirmed to belong to the subgenus Adidocidia Laštovka & Matile, both hybrida and similis cannot be classified on a subgeneric level, since their morphology includes features typical of both Diadocidia s. str. and Adidocidia. A key is provided to the Costa Rican species of Diadocidia.

Phytoplasmas (class Mollicutes) are causal agents of plant diseases with an economic impact on crops or threatening local biodiversity. A survey was conducted from 2012 to 2016 on infected Catharanthus roseus plants that exhibited symptoms reminiscent of phytoplasma infection throughout Costa Rica. A total of 73 plants were collected exhibiting symptoms such as virescence, phyllody, axillary proliferation, little leaf, leaf malformation, chlorosis, or yellowing. All samples were tested by nested PCR using phytoplasma universal and specific primer pairs. Phytoplasma infection was detected in 52 (71.2 %) of the plants collected. Phytoplasmas of six subgroups belonging to 16Sr groups I, III, IX, XIII and XV were identified based on sequencing and in silico RFLP analyses. ´Candidatus Phytoplasma asteris´ (16SrI) was the predominant group among the positive samples (n = 30) showing variety of symptoms and wide distribution from sea level to ca. 1 400 masl in six of the seven Costa Rican provinces. Group 16SrIII was the second most abundant (14 samples); and the remaining three groups were seldom found in C. roseus (8 samples). Moreover, group 16SrXIII phytoplasma was detected for the first time in the country. To the best of our knowledge, this is the first report of natural infection of C. roseus with phytoplasma subgroups 16SrI-B, 16SrI-P, 16SrIII-F, 16SrIX-F, 16SrXIII-A, and 16SrXV-B in Costa Rica and Central America.

The myxomycete genus Colloderma and the species Colloderma oculatum are reported for the first time in Central America. The species was recorded in the high elevations of the Talamanca Mountain Range in Costa Rica during 2014 in a location where the structure of myxomycete assemblages has been historically associated with temperate rather than tropical communities. Comments on the geographical distribution and ecology of the species are included. This record has increased the number of Costa Rican myxomycetes to 213 according to the most updated checklist.

A New Species

We present and illustrate 11 new records of Orchidaceae from Costa Rica, and propose a new combination in Acianthera for Pleurothallis aberrans. Barbosella orbicularis and Myoxanthus speciosus, previously recorded from Costa Rica on the basis of doubtful vouchers, are confirmed to occur in the country and illustrated from Costa Rican vouchers. Warmingia margaritacea is reduced to the synonymy of Warmingia zamorana, a species previously known only from Ecuador. A new species, Epidendrum zunigae is described. This species is similar to E. guanacastense and E. isomerum, from which it differs by the narrow, lanceolate leaves, the greenish flowers, the apical half of the column purple with the clinandrium white, the sepals 11 mm long, and the creamy yellow, cordiform, acute, bicallose lip, wich is somewhat convex in natural position.
