Flight muscle histolysis in Lasius niger queens

Arthur Matte & Johan Billen
T. The foundation of new ant colonies often involves a solitary phase for the newly mated queens. These queens are subject to high food stress during this period that can last several weeks or months until the appearance of the first workers. The food stress is mainly associated with egg laying, larval feeding, and the queens’ own metabolism. The flight muscles of ant queens are histolyzed during early colony foundation, a process that was first...

Trophic eggs in three ponerine ant species: Harpegnathos venator, Odontomachus simillimus and Odontoponera denticulata

, Mitsuhiro Obika, , , , &
Trophic eggs in ants have been well known for a long time, however, published infor- mation of trophic eggs in poneroid ants is relatively scarce. We observed the production and fate of trophic eggs in relation to female castes and reproductive status in three species of ponerine ants in SE Asia. In all species, trophic eggs were principally offered to and eaten by reproductive females. When the trophic eggs were refused by reproductive females, other...

The biology and physiological adaptation of mangrove ants to tidal flooding

Mogens Gissel Nielsen
Mangroves are an extreme biotope where ants are often described as the most abundant and influential group of insects. Yet very few studies have examined how ants survive the often extreme flooding of this biotope. This review summaries knowledge of the distribution and biology of mangrove ants, giving a particular insight into their adaptations, behavioral and physiological, and describes how some ant species survive during the extreme conditions with high temperatures, tidal flooding, very low...

Reproductive differentiation and conflicts in Diacamma: A model system for integrative sociobiology

Kazuki Tsuji
The ponerine queenless ant genus Diacamma has attracted attention for its unique mode of reproductive differentiation through mutilation of the thoracic appendage, gemma, after emergence of monomorphic females. I will begin this review with a description of the scientific history of the discovery of this differentiation mechanism, followed by a review and discussion of the ontogenetic origins, physiological and behavioral effects, and adaptive significance of the gemma and mutilation. Next, I will discuss the adaptive...

The dorsoproximal intramandibular gland in Leptanilla clypeata, a novel exocrine gland in ants

Johan Billen &
Workers of Leptanilla clypeata have a conspicuous epithelial gland underneath the dorsoproximal part of the mandibles that is different from all other intramandibular glands that are so far found in ants. Because of its unique location, we suggest to name this novel structure as the ‘dor- soproximal intramandibular gland’. The gland occurs in an excavation of the mandibular cuticle and is made up by columnar cells with apical microvilli and basal invaginations. The presence of...

Taxonomic review of the ant genus Lordomyrma Emery, 1897 (Hymenoptera, Formicidae) from China, with description of two new species and an identification key to the known species of the world

Xia Liu, & Francisco Hita Garcia
. China is a large country encompassing a wide range of climate zones and bioregions, and hosting several of the world’s biodiversity hotspots. However, even though the country possesses such rich biota, many taxa still remain to be discovered and formally described. In this study we review the myrmicine ant genus Lordomyrma Emery, 1897 from China. We recognize four species for the country, of which we describe two as new: L. bhutanensis (Baroni Urbani, 1977),...

A new species of the rare ant genus, Leptanilla Emery (Hymenoptera: Formicidae) from Eastern Himalaya, India

Sheela Saroj, & Anil Kumar Dubey
Leptanilla ujjalai sp. nov. is decribed and illustrated from the Neora valley National Park, Eastern Himalaya Himalaya, India. The new species differs from the Indian congeners in having four teeth on mandibles and an extended flange on anterior clypeal margin, and from others in flagellomers and petiolar characters. Images of holotype and SEM microphotographs of a paratype are provided. An identification key to workers of the Oriental and Sino-Japanese Leptanilla species is provided.

Field observations on nestmate recruitment to millipedes in the chain- assembling ponerine ant Leptogenys cyanicatena (Formicidae: Ponerinae) in northern Thailand

, , , & Christian Peeters
The foraging behavior of the millipede-specialized predatory ant Leptogenys cyanicatena was observed in Chiang Mai Province, northern Thailand. During the observations, millipede species from two families of the orders Polydesmida (family Paradoxosomatidae) and Spirostreptida (family Harpagophoridae) were hunted by L. cyanicatena. Lone foragers searched for millipedes on the forest floor. When a forager encountered a millipede, she touched the latter with antennae and mouthparts for up to 15 seconds, but never attacked the prey alone....
