The archaeology of Panama, like that of most of lower Central America and the north Andes, has but recently emerged from a purely descriptive stage. The formulation of cultural-geographical divisions in ceramic and sculptural styles — “Cultures” as these are sometimes called — has been the most important attempt at synthesis. Lothrop (1948) envisaged four such “culture areas”: (1) Darien (Panama below the Canal Zone); (2) Coclé (the Pacific watershed in Coclé, Herrera, and Las Tablas Provinces); (3) Veraguas (Pacific highland Panama in the Province of the same name); and (4) Chiriqui (the upland country of Chiriqui Province and adjacent Costa Rica). To these Stirling and Rands (personal communication) have recently added what is probably a fifth, the Atlantic coastal strip above the Canal Zone. The internal coherence or unity of these “culture areas” is of a most general sort.

The Family

The Panamic biogeographic province has long been thought to harbour a rich pyramidellid fauna. In the compilation of Keen (1971) the family is second only to the Turridae in being the most speciose gastropod family in the region, and no less than 350 species are listed. However a number of these have later been recognized to be synonyms, and in the update of the compilation by Skoglund (2002) the number of pyramidellids was reduced to 258.

Glacial lake sediments and glacial geomorphology in Valle de las Morrenas, a glacial trough on the north face of Cerro Chirripó, Costa Rica, provide evidence on high-altitude Pleistocene conditions in Central America. The most recent glacier in the valley (Chirripó stage I) receded very rapidly near the end of the Younger Dryas chronozone. Radiocarbon dates on basal organic sediments from lakes beneath upper, middle, and lower limits of that glacier fall close together, and two-sigma calibrated ages overlap for the period 9700–9600 cal yr B.P. Earliest datable transition sediments from the central lake date to 12,360–11,230 cal yr B.P. Larger, older moraines, and associated trimlines, allowed reconstruction of three paleoglaciers (Chirripó stages II, III, and IV). Computer analysis of hypsometry using published tropical-glacier vertical mass balance profiles yields ELAs of 3506–3523, 3515–3537, and 3418–3509 m, respectively; Chirripó II ELA-estimate positions applied to Chirripó I yield an ELA of 3538–3546 m. We infer minimal temperature depressions of 7.4–8.0°C for the Chirripó I–IV stages. Modeling the behavior of modern tropical glaciers yields basinwide net accumulation estimates of 440–620, 550–830, and 960–1760 mm yr−1 for the Chirripó II, III, and IV stages.

Major Pest

Gnamptogenys triangularis(Mayr), native to the forests of South and Central America, is a predatory ant that feeds on millipedes. In its native range, this species is known from Buenos Aires, Argentina (38.1°S) in the south to Costa Rica (10.4°N) in the north, with records from eight countries in South America (all except Chile, French Guiana, and Paraguay), and the two southernmost countries of Central America (Panama and Costa Rica). The first records ofG. triangularisoutside its native range came from Florida beginning in 1985 (six sites: 25.5°–30.4°N) and Alabama in 1996 (one site: 30.4°N). Here we present the first records ofG. triangularisfrom Mississippi, dating from 2002–2010 (five sites: 30.5°–31.2°N). Based on its South American range, it appears thatG. triangularishas the potential to spread to forests throughout much of the southeastern USA. There are no documented impacts ofG. triangularis,and it seems unlikely that this species will ever become a major pest.

Abstract Ipomoea quamoclit is a fast-growing vine, native to Mexico and Central America, and widely cultivated and introduced to many countries as an ornamental for its attractive foliage and bright flowers. It has escaped from cultivation to become naturalized and invasive in a variety of habitats, where it competes with native vine species and behaves as an agricultural weed. It is listed as invasive in Australia, Papua New Guinea, India, the United States, Brazil, the Galapagos Islands, Costa Rica, Cuba, the Maldives, the Seychelles and many islands in the Pacific Ocean.

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 herein a taxonomic study of Hoplias microlepis based on examination of syntypes and recently collected specimens, including a redescription of the species. Hoplias microlepisoccurs in the Pacific drainages of Panama and Southwestern Costa Rica, in addition to the río Guayas basin in Ecuador and the region near its mouth (río Tumbes, Northwestern Peru). Records of the species on the Atlantic coast of Panama are restricted to the Canal Zone, suggesting dispersal through the Panama Canal. We also designate lectotype and paralectotypes.

Dominical is a small town nestled on the Pacific coast of Costa Rica, where tropical forests spill onto the sandy shores of its world-renowned beaches. Dominical has a laid-back atmosphere of surf shops, open-air restaurants, and children in school uniforms weaving between the puddles and rocks on their way to class. But behind the scenes, something else is going on in Dominical. A clue can be found alongside the dirt road that runs through the center of town, where a billboard for Century 21 Real Estate depicts a happy couple overlooking their oceanfront property, accompanied by the English-language caption “Your Piece of Paradise!” The sign provides a glimpse of the larger forces at play in this remote corner of Central America. A frenzy of speculative real estate development is underway, led by foreigners vying for their own piece of paradise before the remaining lots are all sold by the local farmers whose families have inhabited the land for generations. One such farmer is Juan Carlos Madrigal. I visited Juan Carlos with a group of students in 2008 during one of my annual trips to Costa Rica, to learn more about how local landowners are coping with these pressures. This land has been in his family for a long time, its towering tropical forest encompassing tree plantations, bean, and cocoa crops, and sweeping views of the ocean. After a hike across the property, we cooled off in a swimming hole below a large waterfall, one of many in the area, which thundered down from the lush jungle above, the water volume swollen by seasonal rains. After toweling off we sat down and began the interview, discussing his vision for the future of this land. A humble yet dignified man with wrinkles deepened from decades of farming, Madrigal reported that a group of Americans had recently approached him with an offer to buy his property for a million dollars. Shaking his head, he said that of course he refused.

A New Species

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.
