Based on almost 1,700 recently reared and wild-collected specimens, the genus Dunama Schaus (Notodontidae, Nystaelinae) in Costa Rica is reviewed. Eight species are recorded of which seven are newly described: Dunama jessiehillae Chacón, Dunama jessiebarronae Chacón, Dunama janewaldronae Chacón, Dunama jessiebancroftae Chacón, Dunama janecoxae Chacón, Dunama biosise Chacón, Dunama indereci Chac...

OBJECTIVE To analyze how the tobacco industry influenced tobacco control policymaking in Costa Rica. MATERIALS AND METHODS Review of tobacco industry documents, tobacco control legislation, newspaper articles, and interviewing of key informants. RESULTS During the mid-to-late 1980s, Health Ministry issued several advanced (for their time) smoking restriction decrees causing British American...

— New synonymy is proposed as follows: Pityokteines Fuchs { = Orthotomides Wood), Araptus foveifrons (Schedl) { = interjectus Wood), n. comb., Cryptocarenus seriatus Eggers { = bolivianus Eggers), Hylastes gracilis LeConte {=asper Swaine), Procryphalus utahensis Hopkins {=aceris Hopkins), Scolytodes maurus (Blandford) {=Hexacolus ellipticus Eggers), Scolytus hermosus Wood {=sylvaticus Bright), ...

DNA sequencing brings another dimension to exploration of biodiversity, and large-scale mitochondrial DNA cytochrome oxidase I barcoding has exposed many potential new cryptic species. Here, we add complete nuclear genome sequencing to DNA barcoding, ecological distribution, natural history, and subtleties of adult color pattern and size to show that a widespread neotropical skipper butterfly k...

[1] Although most Central American magmas have a typical arc geochemical signature, magmas in southern Central America (central Costa Rica and Panama) have isotopic and trace element compositions with an ocean island basalt (OIB) affinity, similar to the Galapagos-OIB lavas (e.g., Ba/La < 40, La/Yb > 10, Pb/Pb > 18.8). Our new data for Costa Rica suggest that this signature, unusual for a conve...

The phoronid Phoronopsis albomaculata was collected in subtidal (28– 35 m) sandy sediments in Bahı́a Chatham during a benthic survey designed to describe the biota of Cocos Island (Isla del Coco), Costa Rica, a national park and Human Heritage Site. Occurrence of this widespread species in Cocos Island is the first report of a phoronid for Costa Rican waters and is the second locality recorded f...

UNLABELLED PAHO establishes guidelines that must be met by drug information centers (DIC) and the drug information services (DIS). OBJECTIVE To describe the operations, activities, and resources of the DICs and the DISs affiliated with public institutions of Costa Rica, and their adjustment to the provisions set forth by the PAHO. METHODS Descriptive study conducted in May 2003. The officer...

Perelleschus Wibmer & O’Brien (Curculionidae: Curculioninae: Derelomini) is revised, including the redescription of P. carludovicae (Günther) from Costa Rica and P. rectirostris Voss from Perú, as well as the addition of six new species: P. evelynae, new species, from Colombia and Panama; P. variabilis, new species, from Ecuador; P. biventralis, new species, from Ecuador; P. splendidus, new spe...

The species of the Neotropical genus Cephaloleia Chevrolat, 1836 are revised. We present a key to the known larvae of Cephaloleia (8 species), a key to the 95 species known to occur in Mexico, Central America and the West Indies, and a key to the 138 species known to occur in South America. All identification keys were translated to Spanish. Descriptions for the 214 known species of Cephaloleia...

Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic diversity is distributed within and among populations of the wild rice species Oryza glumaepatula in Costa Rica. We also evaluated the likelihood of gene flow between wild and ...
