A new genus of Parastenocarididae is described from the Neotropical region. Iticocaris gen. nov. is established to include Parastenocaris itica Noodt, 1962. Iticocaris gen. nov. is defined by the following characters: 1) male leg 3 with 2-segmented exopod; 2) first exopodal segment short and rectangular; 3) thumb hypertrophic, longer than the second exopodal segment and inserted on the distal edge of exopod segment 1, occupying the whole distal margin; 4) exopod 2 or apophysis strongly sclerotized, articulated with the exopod segment 1 on its inner margin and curved against the thumb, forming a strong forceps; 5) leg 4 endopod without dimorphism in shape and size vs. minor dimorphism in ornamentation; 6) leg 5 with three setae and 7) lack of the anterolateral furcal seta II. The new genus is monotypic, represented by Iticocaris itica (Noodt, 1962) comb. nov., from El Salvador, Central America. A close relationship is hypothesized between I. itica and the genus Brasilibathynellocaris Jakobi, 1972, the males of which both share the forceps-like elongated apophysis.

Geological Formation

A new genus, Tikuna, is described based on recent collections of adults and nymphs of Choroterpes atramentum Traver from western Costa Rica. All recent collections are from streams on or near the Nicoya Complex, the oldest geological formation in Lower Central America. Tikuna belongs to a lineage of South American Atalophlebiinae (Leptophlebiidae: Ephemeroptera) whose origin is hypothesized to have been in the late Cretaceous–early Tertiary. Some implications of the distribution of Tikuna for theories on the origin of Costa Rica’s biota are discussed.

The Military

The militarycoup d'étatwhich installed General Maximiliano Hernández Martínez as President of El Salvador during December 1931 created a crisis involving the 1923 Washington Treaties. By the terms of these accords, the Central American nadons had pledged to withhold recognition from governments seizing power through force in any of the isthmian republics. Although not a signatory of the treaty, the United States based its recognition policy on this principle. Through this means the State Department had attempted to impose some stability in Central America, by discouraging revolts. With the co-operation of the isthmian governments, United States diplomats endeavored to bring pressure to bear on the leaders of any uprising, to deny them the fruits of their victory, and thus reduce the constant series ofcoupsandcounter-coupsthat normally characterized Central American politics.

Astronomy And Astrophysics

Recently, important efforts have been made to organize and consolidate the Assembly of Central American Astronomers (AAAC), an organization created to contribute to the development of astronomy and astrophysics in Central America, with the help of international cooperation; the Central American Courses in Astronomy and Astrophysics, have been hosted each year by a different national university in Central America (1995: Universidad Nacional Autonoma de Honduras, 1996: Universidad de El Salvador, 1997: Universidad de San Carlos de Guatemala, and 1998: Universidad de Panama). These courses aimed to provide an exchange of knowledge and experience among university staff and students interested in continuing studies in Astronomy and Astrophysics. Regional Observational Campaigns have been organized to train young astronomers in the use of astronomical equipment and observational techniques. It seems that the broad development of astronomy and astrophysics in Central American as a whole, will be possible only when nuclei of astronomers in each of the countries concerned begin to develop many more activities, countries As part of the III Central American Course on Astronomy and Astrophysics (III-CURCAA, April 1997, Guatemala), in a forum about Education and Research in Astronomy in Central America, several important conclusions were stated. In this paper we present the six most relevant conclusions discussed there.
