Additions to the revision of the genus Hemistephanus Enderlein (Hymenoptera: Stephanidae), with inclusion of four taxa and description of two new species Pap. Avulsos de Zool. (São Paulo)
Aguiar,Alexandre Pires.
Four additional species are included in the genus Hemistephanus: H. villosus (Kieffer) comb. n. and H. colombiensis (Ceballos) comb. n., transferred from Megischus and redescribed, and H. costaricensis sp. n. and H. stenogulatus sp. n., described as new; H. artiosulcatus Aguiar is proposed as a junior synonym of H. villosus Kieffer. The males of H. arctatus, H. colombiensis, H. submaculatus, and H. villosus are described for the first time. Much new or additional morphometric data is incorporated and discussed for these species and for H. carinatus, H. erugatus, H. erythrocephalus, H. limpidipennis, H. orfilanus, H. ruficeps, and H. velutinus. New geographical records are presented for all mentioned species and for H. cylindricus. Errata for publications...

Circumscription and nomenclature of Hiraea barclayana, H. reclinata, and H. ternifolia (Malpighiaceae), and of seven species misassigned to them Naturalis
Anderson, C..
A review of collections from Mexico to northern South America that had been primarily determined as H. barclayana, H. reclinata, and H. ternifolia, or synonyms, showed them to include ten species. Misinterpretations were caused by superficial morphological similarities and traditional nomenclatural errors. The species now recognized include six previously described: H. barclayana, H. hookeriana (formerly included in H. reclinata), H. reclinata, H. sanctae-marthae, H. ternifolia, and H. transiens. Four new species are proposed: H. mcvaughii, H. silvicola, and H. venezuelana; H. trianae was previously recognized at varietal level and is elevated to species. A neotype is chosen for H. reclinata. Lectotypes are designated for H. velutina (= H. barclayana) and...

Revision of Hydroides Gunnerus, 1768 (Polychaeta: Serpulidae) from the Eastern Pacific region and Hawaii Naturalis
Bastida-Zavala, J. Rolando; Hove, Harry A. ten.
A taxonomic revision of the Hydroides species (Polychaeta: Serpulidae) from the Eastern Pacific Ocean is presented. Twentyone taxa are described, of which two are widespread (H. diramphus Mörch, 1863 and H. elegans (Haswell, 1883)) and four are Amphiamerican (H. alatalateralis (Jones, 1962), H. gairacensis Augener, 1934, H. salazarvallejoi Bastida-Zavala & Ten Hove, 2003, and H. sanctaecrucis Kroyer [in] Mörch, 1863). Three species are new to science: Hydroides deleoni n. sp., H. panamensis n. sp. and H. trompi n. sp. Morphometric comparisons between H. brachyacanthus Rioja, 1941, H. deleoni n. sp., and H. similis (Treadwell, 1929), between H. chilensis Hartmann-Schröder, 1962, H. cruciger Mörch, 1863 and H. panamensis n. sp., and between H....

Scorpionism in Central America, with special reference to the case of Panama J. Venom. Anim. Toxins incl. Trop. Dis.
Borges,A; Miranda,RJ; Pascale,JM.
Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Costa Rica are produced by species in the genus Centruroides that are only mildly toxic to humans despite the existence of ion channel-active toxins in their venoms. Regional morbidity is low with the exception of Panama, where an incidence of 52 cases per 100,000 inhabitants was recorded for 2007, with 28 deaths from 1998 to 2006. Taxa belonging to the genus Tityus (also present in the Atlantic coast of...

Current challenges for confronting the public health problem of snakebite envenoming in Central America J. Venom. Anim. Toxins incl. Trop. Dis.
Gutiérrez,José María.
Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally known as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further...

Farmer Organization, Collective Action and Market Access in Meso-America AgEcon
Hellin, Jonathan; Lundy, Mark; Meijer, Madelon.
The global agricultural economy is changing. Commodity prices are declining, and producers increasingly supply complex value chains. There is growing interest in how farmers can benefit from emerging market opportunities. Farmers are encouraged to produce high value crops and engage in value-adding activities such as agro-processing. Farmer organization and collective action are often seen as key factors in enhancing farmers’ access to markets. Often too little attention is directed at a) the most appropriate types of organization, b) whether the public and/or private sector is best placed to support their formation, and c) the conditions necessary for ensuring their economic viability. This paper reports on research in Mexico and Central America that...

The Impact of the Central America Free Trade Agreement on the Central American Textile Maquila Industry AgEcon
Jansen, Hans G.P.; Morley, Samuel A.; Kessler, Gloria; Pineiro, Valeria; Sanchez, Marco V.; Torero, Maximo.
While the Central America Free Trade Agreement (CAFTA) remains a hotly debated issue in all five Central American countries that are part of the treaty, most discussions are based on preconceived opinions rather than grounded in research-based results. The point of departure of the paper is that the provisions in the agreement concerning the textile maquila industry are likely to have a significant impact on household welfare, despite the already existing preferential access of textile maquila exports to the U.S. market under the rules of origin set by the Caribbean Basin Initiative (CBI) and the U.S.–Caribbean Basin Trade Partnership Act (CBTPA). What CAFTA does for maquila production in Central America is to make permanent and expand the liberalized...

Can the Private Sector be Competitive and Contribute to Development through Sustainable Agricultural Business? A Case Study of Coffee in Latin America AgEcon
Kilian, Bernard; Pratt, Lawrence; Jones, Connie; Villalobos, Andres.
Latin America's coffee market continues in economic crisis. Sustainable coffee production and certification is one option for economic recuperation and social and environmental sustainability for the region's coffee producers. This paper explores four viable certification processes (Organic, Fair Trade, Rainforest Alliance, and Utz Kapeh) by first defining their requirements. Then, an assessment of microeconomic impacts is given, where the production processes of sustainable and conventional coffee are evaluated and compared. Finally, the paper presents their future relevance and entrepreneurial potential by considering long-term market perspectives.

A new species of Roeboides (Teleostei: Characidae) from Costa Rica and Panama, with a key to the middle American species of the genus Neotropical Ichthyology
Matamoros,Wilfredo A.; Chakrabarty,Prosanta; Angulo,Arturo; Garita-Alvarado,Carlos A.; McMahan,Caleb D..
A new species of Roeboides is described from the Pacific slope of Costa Rica and Panama. Roeboides bussingi differs from all other Central American Roeboides and all members of the R. guatemalensis species group by the following combination of characters: presence of 18-22 scales above the lateral line (vs. 12-16 in R. dientito); 15-22 scales below the lateral line (vs. 10-14 in R. dientito, and 20-24 in R. loftini); an inconspicuous, sometimes absent, crescent-shaped humeral spot (vs. a large round, conspicuous humeral spot in R. carti, R. dayi, R. dientonito, R. ilseae, R. loftini,and R. occidentalis); a small wedge-shaped spot that does not reach the lateral line (vs. a large spot crossing the lateral line in R. guatemalensis); a teardrop shaped caudal...

Taxonomic study of Hoplias microlepis (Günther, 1864), a trans-Andean species of trahiras (Ostariophysi: Characiformes: Erythrinidae) Neotropical Ichthyology
Mattox,George M. T.; Bifi,Alessandro G.; Oyakawa,Osvaldo T..
The Hoplias malabaricus species group represents one of the most complexes taxonomical problems in the systematics of Neotropical fishes, including specimens widely distributed in most drainages of South America and part of Central America with great variation or overlap of putative diagnostic characters. The large number of nominal species, many of which without known type material, renders the problem more complicated. Currently, at least three nominal species can be included in the Hopliasmalabaricusspecies group based on the form of the medial margins of dentaries and presence of tooth plates on the tongue: Hoplias malabaricus, H. teres, and H. microlepis, the latter representing the only exclusively trans-Andean known species of the genus. We present...

Reproductive life history of Heterandria bimaculata (Heckel, 1848) (Poeciliinae: Poeciliidae) in the Honduran interior highlands: trait variation along an elevational gradient Neotropical Ichthyology
Olinger,Charles T.; Peoples,Brandon K.; Frimpong,Emmanuel A..
Abstract This study examined reproductive traits and growth rates of Heterandria bimaculata (Poeciliidae) in Cusuco National Park (CNP), a cloud forest reserve in northern Honduras, Central America. In CNP, H. bimaculata occurs in the absence of other fish species and major invertebrate predators along an approximately 1000 m elevation gradient. This allowed for the examination of trait variation along the gradient without the confounding effects of interspecific interactions or habitat patchiness. Heterandria bimaculata exhibited traits characteristic of a low-predation environment: balanced sex ratio, slow growth, late maturity and large female size. Females produced more, smaller eggs from upstream to downstream, but overall reproductive allocation...

Edge-drilling behavior in the predatory gastropod Notocochlis unifasciata (Lamarck, 1822) (Caenogastropoda, Naticidae) from the Pacific coast of Panama: taxonomic and biogeographical implications Naturalis
Rojas, Alexis; Hendy, Austin; Dietl, Gergory P..
We conducted a laboratory study to determine drillhole siteselectivity patterns in the predatory behavior of Notocochlis unifasciata (Lamarck, 1822), which is a common naticid gastropod on the eastern Pacific coast of Central America, preying on two infaunal venerid bivalves – the thin-shelled and weakly ornamented Leukoma grata (Say, 1831) and the thick-shelled and strongly ornamented Iliochione subrugosa (Wood, 1828). Spatial patterns of drillhole distribution indicate strong preferences for drilling the umbonal region and the ventral edge of the shell, with the proportion of edge- to wall-drilling attacks increasing in thicker, strongly ornamented prey that were larger than their predator’s own size. Drilling patterns from museum and beach...

Soil conservation and technical efficiency among hillside farmers in Central America: a switching regression model AgEcon
Solis, Daniel; Bravo-Ureta, Boris E.; Quiroga, Ricardo E..
The main objective of this paper is to evaluate and analyse technical efficiency (TE) levels for hillside farmers under different levels of adoption of soil conservation in El Salvador and Honduras. A switching regression model is implemented to examine potential selectivity bias for high and low level adopters, and separate stochastic production frontiers, corrected for selectivity bias, are estimated for each group. The main results indicate that households with above-average adoption show statistically higher average TE than those with lower adoption. Households with higher adoption have smaller farms and display the highest partial output elasticity for land. Constraints in the land and credit markets are likely explanations for these differences. In...
