P. FOX, Adrian A. SMITH, Joshua C. GIBSON & Daniel R. SOLIS Abstract This study aims to contribute to the neglected topic of larval biology in ants. The number of larval instars for three differ- ent species of trap-jaw ants, Odontomachus meinerti FOREL, 1905, Odontomachus bauri EMERY, 1892, and Odontomachus brunneus (PATTON, 1894) was estimated to three based on the maximum width frequency distributions of head cap- sules from worker and male larvae. The obtained number of larval instars was smaller than from a previous report with another species in the genus, indicating possible interspecific variation. Larvae of different sexes and instars among the three different species were generally identical, differing merely by relative dimensions and patterns of hair distribution. Dorsal "doorknob" protuberances were recorded for the first time in the genus, and observed being used to fix larvae onto nest walls. From observing several individuals, we suggest the ornamentation of spiracle peritremes and the types of body protuberances are useful characters for larval taxonomy within this group. Moreover, a few individuals were found pos- sessing anomalous structures which are reminiscent of characters from related taxa. Finally, some brief observations are made on an unidentified parasite found inside some mature larvae of O. bauri.

    Myrmecological News 20 25-36 Online Earlier, for print 2014 The evolution and functional morphology of trap-jaw ants (Hymenoptera: Formicidae) Fredrick J. LARABEE & Andrew V. SUAREZ Abstract We review the biology of trap-jaw ants whose highly specialized mandibles generate extreme speeds and forces for predation and defense. Trap-jaw ants are characterized by elongated, power-amplified mandibles and use a combination of latches and springs to generate some of the fastest animal movements ever recorded. Remarkably, trap jaws have evolved at least four times in three subfamilies of ants. In this review, we discuss what is currently known about the evolution, morphology, kinematics, and behavior of trap-jaw ants, with special attention to the similarities and key dif- ferences among the independent lineages. We also highlight gaps in our knowledge and provide suggestions for future research on this notable group of ants.

  • For Submission As a Note Green Anole (Anolis Carolinensis) Eggs
    For submission as a Note Green Anole (Anolis carolinensis) Eggs Associated with Nest Chambers of the Trap Jaw Ant, Odontomachus brunneus Christina L. Kwapich1 1Department of Biological Sciences, University of Massachusetts Lowell One University Ave., Lowell, Massachusetts, USA [email protected] Abstract Vertebrates occasionally deposit eggs in ant nests, but these associations are largely restricted to neotropical fungus farming ants in the tribe Attini. The subterranean chambers of ponerine ants have not previously been reported as nesting sites for squamates. The current study reports the occurrence of Green Anole (Anolis carolinensis) eggs and hatchlings in a nest of the trap jaw ant, Odontomachus brunneus. Hatching rates suggest that O. brunneus nests may be used communally by multiple females, which share spatial resources with another recently introduced Anolis species in their native range. This nesting strategy is placed in the context of known associations between frogs, snakes, legless worm lizards and ants. Introduction Subterranean ant nests are an attractive resource for vertebrates seeking well-defended cavities for their eggs. To access an ant nest, trespassers must work quickly or rely on adaptations that allow them to overcome the strict odor-recognition systems of ants. For example the myrmecophilous frog, Lithodytes lineatus, bears a chemical disguise that permits it to mate and deposit eggs deep inside the nests of the leafcutter ant, Atta cephalotes, without being bitten or harassed. Tadpoles inside nests enjoy the same physical and behavioral protection as the ants’ own brood, in a carefully controlled microclimate (de Lima Barros et al. 2016, Schlüter et al. 2009, Schlüter and Regös 1981, Schlüter and Regös 2005).

Crepuscular and nocturnal foragers travel up to 8 m to search for arthropod prey in the canopy, where silhouettes of leaves and branches potentially provide directional information. Keywords: We investigated the relevance of visual cues (canopy, horizon patterns) during navigation in O. hastatus. Arboreal ants Laboratory experiments using a captive ant colony and a round foraging arena revealed that an artificial Atlantic forest canopy pattern above the ants and horizon visual marks are effective orientation cues for homing O. has- Canopy orientation tatus. On the other hand, foragers that were only given a tridimensional landmark (cylinder) or chemical Ponerinae marks were unable to home correctly. Navigation by visual cues in O. hastatus is in accordance with other Trap-jaw ants diurnal arboreal ants. Nocturnal luminosity (moon, stars) is apparently sufficient to produce contrasting Visual cues silhouettes from the canopy and surrounding vegetation, thus providing orientation cues.

En esta tesis se estudiaron de forma integral la sistemática y ecología de una subfamilia de hormigas, las ponerinas. Esta subfamilia predomina en regiones tropicales y neotropicales, estando presente en Argentina desde el norte hasta la provincia de Buenos Aires. Se utilizó un enfoque integrador, combinando análisis genéticos con morfológicos para estudiar su diversidad, en combinación con estudios ecológicos y comportamentales para estudiar la dominancia, estructura de la comunidad y posición trófica de las Ponerinas. Los resultados sugieren que la diversidad es más alta de lo que se creía, tanto por que se encontraron nuevos registros durante la colecta de nuevo material, como porque nuestros análisis sugieren la presencia de especies crípticas. Adicionalmente, demostramos que en el PN Iguazú, dos ponerinas: Dinoponera australis y Pachycondyla striata son componentes dominantes en la comunidad de hormigas. Análisis de isótopos estables revelaron que la mayoría de las Ponerinas ocupan niveles tróficos altos, con excepción de algunas especies arborícolas del género Neoponera que dependerían de néctar u otros recursos vegetales.

  • Sitemate Recognition: the Case of Anochetus Traegordhi (Hymenoptera; Formicidae) Preying on Nasutitermes (Isoptera: Termitidae) by B
    569 Sitemate Recognition: the Case of Anochetus traegordhi (Hymenoptera; Formicidae) Preying on Nasutitermes (Isoptera: Termitidae) by B. Schatz', J. Orivel2, J.P. Lachaud", G. Beugnon' & A. Dejean4 ABSTRACT Workers of the ponerine ant Anochetus traegordhi are specialized in the capture of Nasutitermes sp. termites. Both species were found to live in the same logs fallen on the ground of the African tropical rain forest. A. traegordhi has a very marked preference for workers over termite soldiers. The purpose of the capture of soldiers, rather than true predation, was to allow the ants easier access to termite workers. During the predatory sequence, termite workers were approached from behind, then seized and stung on the gaster, while soldiers were attacked head on and stung on the thorax. When originating from a different nest-site log than their predator ant, termites were detected from a greater distance and even workers were attacked more cau- tiously. Only 33.3% of these termite workers were retrieved versus 75% of the attacked same-site termite workers. We have demonstrated that hunting workers can recognize the nature of the prey caste (workers versus termite soldiers) and the origin of the termite colony (i.e. sharing or not the log where the ants were nesting), supporting the hypothesis that hunting ants can learn the colony odor of their prey. This, in addition to the nest-site selection of A. traegordhi in logs occupied by Nasutitermes can be considered as a first step in termitolesty. Key words: Anochetus, Nasutitermes prey recognition, predatory behavior. INTRODUCTION During their 100 million years of coexistence, ants and termites have been engaged in a coevolutionary arms race, with ants acting as the aggressor and employing many predatory strategies while termites are the prey presenting several defensive reactions (1-11511dobler & Wil- 'LEPA, CNRS-UMR 5550, Universite Paul-Sabatier, 118 route de Narbonne, 31062 Toulouse cedex, France (e-mail: schatz©cict.fr)(correspondence author: B.
