The pathological findings in three cases of equine phycomycosis in Costa Rica are described. Two cutaneous (Pythium sp) and one nasal lesion (Conidiobolus) were observed.

Three hundred and thirty two species of polychaetes belonging to 50 families are reported for Costa Rica based on previously published reports. In a few families, available material was re-examined and appropriate changes in species identifications were made. Only three species, (Glycera oxycephala Ehlers, 1887; Hemipodia pustulata (Friedrich 1956); and Scolepis (Scolepis) squamata (Miller, 180...

Two species of oribatid mites of the genus Benoibates (Oribatida, Oripodidae), i.e., Benoibatesbolivianus Balogh & Mahunka, 1969(a) and Benoibatesminimus Mahunka, 1985, are recorded for the first time in Costa Rica. Both are redescribed in details, using drawings, images and SEM micrographs, on the basis of Costa Rican specimens. An identification key to the known species of Benoibates is given.

Recent taxonomic works have recognized only two species of spiny pocket mice of the genus Heteromys (Rodentia: Heteromyidae) from Costa Rica. Within Costa Rica, the widespread H. desmarestianus is considered to occur throughout the wet Caribbean lowlands, as well as at middle and high elevations on the Caribbean and Pacific slopes of the country’s main montane systems. In contrast, H. oresterus...

OBJECTIVES There is evidence that health care during pregnancy is a crucial component in ensuring a safe delivery. Because the infant mortality rate in Costa Rica is almost half the rate of Panama, the researchers tested the hypothesis that women in Costa Rica are more knowledgeable about prenatal health care than women in neighboring Panama. METHODS A multiple-choice survey was used to evalu...

The mortality rate due to snakebite envenomation in Costa Rica was estimated from 1952 to 1993. The highest mortality was observed during the 1950s and 1960s, with the highest rate of 4.83 per 100,000 population in 1953. In contrast, a rate of 0.2 per 100,000 population per year was estimated from 1990 to 1993. The most conspicuous decline in mortality occurred after 1970. The highest mortality...

This is the first report of the sipunculan Aspidosiphon (Aspidosiphon) elegans (Chamisso & Eysenhardt, 1821) in the tropical eastern Pacific. With this species the number of coral borers rises to 18 for this region. The upogebiidid crustacean Pomatogebia rugosa (Lockington, 1878) was reported previously (as Upogebia rugosa) from coral colonies in the Gulf of California, Mexico, and from coral r...

After finding distinct clades in a molecular phylogeny for Nepticulidae that could not be placed in any known genera and discovering clear apomorphic characters that define these clades, as well as a number of Neotropical species that could be placed in known genera but were undescribed, three new genera and nine new species are here described from the Neotropics: Stigmella gallicola van Nieuke...

Socioeconomic Development, Health Interventions and Mortality Decline in Costa Rica. Rosero-Bixby, L. (Department of Population Planning, University of Michigan, Ann Arbor, USA). Scand J Soc Med 1990, suppl 46: 33-42. Costa Rica, whose life expectancy was 74 years by 1985, has reached a health level comparable to a developed country. The health achievements of this country are product of politi...
