Characteristics of the cocoon and natural history of the gregarious Meteorus restionis sp. n. (Hymenoptera, Braconidae, Meteorinae) from Costa Rica

Cotithene Voss, a previously monotypic genus of Neotropical derelomine flower weevils (Curculionidae: Derelomini), is revised, with provision of a key to the species, cladistic analysis and notes on its natural history. The following six new species are described: C. anaphalanta (Costa Rica), C. dicranopygia (Costa Rica), C. leptorhamphis (Costa Rica, Panama), C. melanoptera (Venezuela), C. stratiotricha (Costa Rica) and C. trigaea (Costa Rica). The monophyly of Cotithene is supported by the characters of a dorsomedially expanded, carinate rostrum, ventrally angulate head, long and anteriorly directed setation on the anterior margin of the prosternum and an apicodorsally expanded aedeagus with paired sclerites in the male, and subcontiguous to separated procoxal cavities in the female. Particularly the males of several species have intriguing and allometrically scaled modifications on the head (triangular projections, long setae) and pronotum (expansion, tumescences), which possibly play a role in male-to-male conflicts. Cotithene species are specialized to visit and reproduce on a narrow range of typically closely related species of Cyclanthaceae. The adults do not function as pollinators, and the herbivorous larvae develop in the fruiting organs of their hosts, frequently triggering the abortion of infructescences. An analysis of 12 taxa (5 outgroup, 7 ingroup) and 32 morphological characters yielded a single most parsimonious cladogram (L = 38, CI = 89, RI = 93) with the topology (C. dicranopygia, (C. stratiotricha, ((C. leptorhamphis, C. trigaea), (C. globulicollis Voss, (C. anaphalanta, C. melanoptera))))). The evolution of morphological traits and host shifts is examined in light of the proposed phylogeny.

A knowledge of life cycle and natural history are often important prerequisites to studies of population biology in butterflies. Although studies on the systematics and broad distribution patterns of that familiar New World Tropical group, the Ithomiinae, have been conducted (Seitz, 194; Fox, 1956; Fox, 1968), a lot remains to be known about the biology of many species in Central America. This is surprising in light of the considerable interest in these butterflies as members of mimicry complexes. In this spirit, this paper summarizes life cycle and natural history data on a clear wing ithoreiine Hymenitis nero (Hewitson) (Nymphalidae: Ithomiinae) in Costa Rica. Similar studies of several other sympatric ithomiines have either been completed (Young, in prep.) or begun, as a preliminary step towards understanding the local patterns of diversity of this family in selected tropical plant communities.

This paper summarizes the life cycle and some aspects of natural history of the tropical pierid, Dismorphia virgo (Dismorphiinae) in Costa Rica. The precise taxonomic status of the butterfly in Central America has not been established, and it may represent a variable northern isolate of the common South American D. critomedia. Therefore, independent of whether the Central American form discussed in this paper has achieved full species status as the more northern virgo or is a subspecies or variety of critomedia evolving towards species status, this paper provides new information on the biology of the butterfly in Costa Rica. The establishment of precise taxonomic position awaits further study, and for the present purpose, I refer to the butterfly as D. virgo.

Abstract We conducted a brief radiotelemetry study of Scotinomys teguina (Alston’s singing mice) in Costa Rica to better understand their natural history and spatial ecology. We radio-collared five mice, one of which was quickly eaten by a pitviper. The home ranges of the remaining mice were in moist habitats and ranged from 255 to 1620 m2, with extensive overlap between adjacent individuals. Singing mice, being small, diurnal, uniformly dark-colored insectivores foraging in dense forest floor habitats, have an adaptive syndrome similar to soricids, which may be due to the low diversity of shrews through Central America.

The Variable Harlequin Toad (Atelopus varius) has suffered extensive declines in Panama and Costa Rica.Of 169 previously documented populations, only seven are known to survive. Herein we review the status of the survivingpopulations of this species in Costa Rica, describing the results of random visits to five of the seven survivingpopulations during the last six years, novel information on the natural history of three of these, and the results of amonitoring program of one continuous year on one of them. We identify three distinct morphs that might be the onlysurvivors of what once was a wide array of phenotypic color patterns.

The genus Azteca is endemic to the American tropics, where they are abundant arboreal ants. The taxonomy and natural history of the Costa Rican fauna is reviewed, and the A. aurita group is recognized and revised globally. The following synonymies are proposed: A. laticeps Forel under A. chartifex Forel; A. championi Forel, A. eiseni Pergande, A. raptrix Forel, A. ursina Forel, and A. xysticola Forel under A. forelii Emery; A. rossi and A. surubrensis Forel under A. gnava Forel; A. major Forel under A. instabilis (F. Smith); A. prorsa Wheeler under A. longiceps Emery; A. patruelis Forel under A. pittieri Forel; A. nigriventris Forel and A. rectinota Forel under A. velox Forel; A. silvae Forel under A. aurita Emery; A. pruinosa Mann under A. lallemandi Forel; A. lacrymosa Forel under A. pilosula Forel; A. fiebrigi Forel, A. clariceps Santschi, and A. pallida Stitz under A. schimperi Emery; A. columbica Forel under A. jelskii Emery; A. mexicana Emery under A. sericea (Mayr). Azteca velox nigra Forel is raised to species. Azteca aurita pilosula is removed from synonymy and raised to species. The following new species are described: A. sericeasur, A. flavigaster, A. oecocordia, A. nanogyna, and A. quadraticeps.
