Ant gardens of Camponotus (Myrmotarsus) irritabilis (Hymenoptera: Formicidae: Formicinae) and Hoya elliptica (Apocynaceae) in Southeast Asia

Andreas Weissflog, Eva Kaufmann & Ulrich Maschwitz
Camponotus irritabilis (Formicidae: Formicinae) and Hoya elliptica (Apocynaceae) are very closely associated in ant gardens in Malaya and Sumatra. Ants and epiphyte partners have some characteristics that make them especially suitable for this association: The ants selectively retrieve the seeds of their epiphyte partners, and they fertilize their carton nests on which the plants are growing. In comparison to non-myrmecophytic Hoya coriacea, Hoya elliptica performs an extensive root growth as long as growing on moist...

Ants in the city, a preliminary checklist of Formicidae (Hymenoptera) in Macau, one of the most heavily urbanized regions of the world

, &
Macau is a small territory in South East China and one of the most densely populated regions in the world. Previous studies on insect groups have shown that a relatively diverse, yet specific, fauna could still survive in this region. However, to this point, studies on the myrmecofauna of Macau are scarce and to date no species checklist exists. Here, we present the first checklist of Macanese ant species by combining results from recent ant...

Colony structure and life history of Lioponera daikoku (Formicidae: Dorylinae)

Naoto Idogawa & Shigeto Dobata
We report the colony structure and life history of the basal doryline ant Lioponera daikoku in Kyoto Prefecture, Japan. The following characteristics were observed in the field: (1) nests were always in the cavities of dead bamboo stems on the forest floor; (2) the colonies were small, averaging 10 workers with a single dealate queen; (3) each queen had four ovarioles (2 + 2), while workers had two (1 + 1); (4) alate sexuals with...

A Taxonomic Study on the Genus Strumigenys Smith, 1860 (Hymenoptera: Formicidae) from Korea with a description of new species

Min-Soo Dong &
Korean species of the genus Strumigenys Smith, 1860 are revised. One new species, Strumigenys calvus sp. nov. and two newly recorded species are presented in this study. The records of Strumigenys sp. in Choi (1995) are here identified as S. kumadori based on the examination of the description and taxonomic key provided by Choi (1995). In order to facilitate proper identification of Korean Strumigenys species, we provide a taxonomic key for all known South Korean...

Protection from herbivores varies among ant genera for the myrmecophilic plant Leea aculeata in Malaysian Borneo

Hannah F. Burger, Kamila Vondráčková, Mateusz Skłodowski, , Daisy H. Dent, Kevin Wallace & Tom M. Fayle
Some plants use food bodies to attract ants that then provide protection from herbivory. A brief report from 1898 describes the myrmecophilic plant Leea aculeata Bl. as bearing food bodies on its young shoots, which accumulate when they are not harvested by ants. However, ant efficacy in deterring herbivores and consequences for herbivory rates remain unknown. Here we investigate (1) which ant taxa patrol these plants and whether they remove significant numbers of food bodies,...

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....

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.
