Hymenoptera, Formicidae)
Belg. J. Zool. - Volume 123 (1993) - issue 2 - pages 159-163 - Brussels 1993 Manuscript received on 25 June 1993 NOTES ON THE ABERRANT VENOM GLAND MORPHOLOGY OF SOME AUSTRALIAN DOLICHODERINE AND MYRMICINE ANTS (HYMENOPTERA, FORMICIDAE) by JOHAN BILLEN 1 and ROBERT W. TAYLOR 2 1 Zoological Institute, University of Leuven, Naamsestraat 59, B-3000 Leuven, Belgium 2 Australian National Insect Collection, CSIRO, GPO Box 1700, Canberra ACT 2601, Australia SUMMARY Two Australian species of Dolichoderus Lund, and one of Leptomyrmex Mayr (both sub family Dolichoderinae), have venom glands with two long, slender secretory fil aments. In this regard they resemble previously analysed ants of the subfamily Myrmicinae, rather tban other dolichoderines. Alternatively, four Meranoplus Smith species (subfamily Myrmicinae) bave short, knob-like filaments, like tbose of previously reported dolicboderines, and unlike otber myrmicines. Features of venom gland morpbology are thus Jess constant or diagnostically reliable for these subfamilies than was previously supposed. Keywords : venom gland, morphology, Dolichoderus, Leptomyrmex, Meranoplus. INTRODUCTION The ant subfamily Dolichoderinae, with its apparent sister-group the Aneuretinae (TRANŒLLO and JAYASURIYA, 1981), is characterized by the distinctive and peculiar configuration of its abdominal exocrine glandular system (BILLEN, 1986). These ants alone have a Pavan's gland, and their pygidial glands are so hypertrophied as to have been previously regarded as separate 'anal glands', which were thought unjquely to characterize them. T he venom gland of these ants has also been considered urnque in possessing two very short knob-bke secretory filaments, whjch is considered to characterize the Dolichoderinae (HôLLDOBLER and WILSON, 1990). Morphological descriptions of the dolichoderine venom gland are available for representatives of the genera Azteca, Bothriomyrmex, Dolichoderus, Iridomyr mex, Liometopum and Tapinoma (PAVAN, 1955; PA VAN and RoNCHETTI, 1955 ; BLUM and HERMANN, 1978b ; BILLEN, 1986).

MOULDS Entomology Department, Australian Museum, 6 College Street, Sydney NSW 2010, Australia [email protected] ABSTRACT. Psaltoda antennetta n.sp. and P. maccallumi n.sp. are cicadas restricted to rainforest habitats in northeastern Queensland. Psaltoda mossi n.sp. is far more widespread, ranging through eastern Queensland to northern New South Wales. Psaltoda antennetta is remarkable for its foliate antennal flagella, an attribute almost unique among the Cicadoidea. Relationships of these three species are discussed and a revised key to all Psaltoda species provided. MOULDS, M.S., 2002. Three new species of Psaltoda Stål from eastern Australia (Hemiptera: Cicadoidea: Cicadidae). Records of the Australian Museum 54(3): 325–334. The genus Psaltoda Stål is endemic to eastern Australia.

Immediate Impacts of Invasion by Wasmannia Auropunctata (Hymenoptera: Formicidae) on Native Litter Ant Fauna in a New Caledonian Rainforest
Austral Ecology (2003) 28, 204–209 Immediate impacts of invasion by Wasmannia auropunctata (Hymenoptera: Formicidae) on native litter ant fauna in a New Caledonian rainforest J. LE BRETON,1,2* J. CHAZEAU1 AND H. JOURDAN1,2 1Laboratoire de Zoologie Appliquée, Centre IRD de Nouméa, B.P. A5, 98948 Nouméa CEDEX, Nouvelle-Calédonie (Email: [email protected]) and 2Laboratoire d’Ecologie Terrestre, Université Toulouse III, Toulouse, France Abstract For the last 30 years, Wasmannia auropunctata (the little fire ant) has spread throughout the Pacific and represents a severe threat to fragile island habitats. This invader has often been described as a disturbance specialist. Here we present data on its spread in a dense native rainforest in New Caledonia. We monitored by pitfall trapping the litter ant fauna along an invasive gradient from the edge to the inner forest in July 1999 and March 2000. When W. auropunctata was present, the abundance and richness of native ants drops dramatically. In invaded plots, W. auropunctata represented more than 92% of all trapped ant fauna. Among the 23 native species described, only four cryptic species survived. Wasmannia auropunctata appears to be a highly competitive ant that dominates the litter by eliminating native ants. Mechanisms involved in this invasive success may include predation as well as competitive interactions (exploitation and interference). The invasive success of W. auropunctata is similar to that of other tramp ants and reinforces the idea of common evolutionary traits leading to higher competitiveness in a new environment. Key words: ant diversity, biological invasion, New Caledonia, Wasmannia auropunctata. INTRODUCTION This small myrmicine, recorded for the first time in New Caledonia in 1972 (Fabres & Brown 1978), has In the Pacific area, New Caledonia is recognized as a now invaded a wide array of habitats on the main unique biodiversity hot spot (Myers et al.

The Functions and Evolution of Social Fluid Exchange in Ant Colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C
ISSN 1997-3500 Myrmecological News myrmecologicalnews.org Myrmecol. News 31: 1-30 doi: 10.25849/myrmecol.news_031:001 13 January 2021 Review Article Trophallaxis: the functions and evolution of social fluid exchange in ant colonies (Hymenoptera: Formicidae) Marie-Pierre Meurville & Adria C. LeBoeuf Abstract Trophallaxis is a complex social fluid exchange emblematic of social insects and of ants in particular. Trophallaxis behaviors are present in approximately half of all ant genera, distributed over 11 subfamilies. Across biological life, intra- and inter-species exchanged fluids tend to occur in only the most fitness-relevant behavioral contexts, typically transmitting endogenously produced molecules adapted to exert influence on the receiver’s physiology or behavior. Despite this, many aspects of trophallaxis remain poorly understood, such as the prevalence of the different forms of trophallaxis, the components transmitted, their roles in colony physiology and how these behaviors have evolved. With this review, we define the forms of trophallaxis observed in ants and bring together current knowledge on the mechanics of trophallaxis, the contents of the fluids transmitted, the contexts in which trophallaxis occurs and the roles these behaviors play in colony life. We identify six contexts where trophallaxis occurs: nourishment, short- and long-term decision making, immune defense, social maintenance, aggression, and inoculation and maintenance of the gut microbiota. Though many ideas have been put forth on the evolution of trophallaxis, our analyses support the idea that stomodeal trophallaxis has become a fixed aspect of colony life primarily in species that drink liquid food and, further, that the adoption of this behavior was key for some lineages in establishing ecological dominance.
