Megalomyrmex Acauna
''Megalomyrmex'' is a genus of ant in the subfamily Myrmicinae. The genus is known only from the Neotropics, where some of the species are specialized parasites or predators of Attini. Description It is difficult to characterize morphologically. Bolton (2003) placed it in the tribe Solenopsidini, but with multiple exceptions to the diagnostic characters for the tribe. The tribal characters include a bicarinate clypeus and a median clypeal seta. Most ''Megalomyrmex'' species have a smoothly convex clypeus with no trace of the bicarinate condition, and most have abundant clypeal setae with no distinct or differentiated median seta. In Bolton's (1994) key to genera, ''Megalomyrmex'' keys in multiple places because of variability in mandibular dentition. Nevertheless, the genus has a distinctive habitus: the antenna is 12-segmented with a 3-segmented club; the general integument is smooth and shiny without coarse sculpture or dull areas; the promesonotum is evenly arched, with ...

Megalomyrmex Modestus
''Megalomyrmex modestus'' is a Neotropical species of ants in the subfamily Myrmicinae. Known from Costa Rica, Panama, Colombia, Venezuela. In Costa Rica, ''M. modestus'' is found in mature wet forest of the Atlantic slope. Although it occurs at sea level, it is most abundant at middle elevations, 500–800 m. Nests are subterranean and very large. From these nests, inconspicuous covered galleries extend large distances up trees and under liana stems, and workers may be found under epiphyte An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phoroph ... mats in the canopy. Workers tend Coccoidea under the shelters. Workers are occasionally collected at baits on the forest floor, but in general they are not often seen as exposed foragers. References * * Myrmicinae Insects describ ...

Megalomyrmex Wettereri
''Megalomyrmex wettereri'' is a Neotropical species of ants in the subfamily Myrmicinae. ''Megalomyrmex wettereri'' is known from two lowland rainforest sites: Barro Colorado Island in Panama and La Selva Biological Station in Costa Rica. Nest usurpation Observations from Barro Colorado were the subject of Adams et al. (2000). Colonies of ''M. wettereri'' were found occupying abandoned nests of '' Cyphomyrmex longiscapus''. The fungus gardens of the ''Cyphomyrmex'' were intact and the '' Megalomyrmex'' workers were observed feeding on the fungal symbiont. When lab colonies of ''M. wettereri'' were placed in contact with colonies of ''Cyphomyrmex longiscapus'', the ''M. wettereri'' aggressively attacked, killing the adult workers. When presented with ''Cyphomyrmex'' larvae A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megalomyrmex Symmetochus
''Megalomyrmex symmetochus'' is a species of ant in the subfamily Myrmicinae. It is native to Panama. ''M. symmetochus'' was discovered by William M. Wheeler in late July 1924 in the fungus gardens of the attine ''Sericomyrmex amabilis'' of Barro Colorado Island. Description Workers are 3 to 3.5 mm long, with small, feebly convex eyes, that are probably adapted to living within the dark fungal gardens of their host. Very small ocelli are only sometimes present. Workers are yellowish red, with mandibles, funiculi, the posterior half of the first segment of the gaster and the sutures of the thorax and pedicels brown. The tip of the gaster is yellowish. The female is almost 4 mm long. She has larger eyes than the workers and distinct ocelli. Otherwise, they look very similar to workers. Each ocellus has a black margin internally. The wings are yellowish hyaline and iridescent, with veins and pterostigma The pterostigma (plural: pterostigmata) is a group of spec ...
