The twists and turns of biological research: first record of an ergatoid queen in the ant genus Pheidole Westwood, 1839, and implications for dispersal and life history

David Emmanuel M. General, Perry Archival C. Buenavente & Christian Peeters
An ergatoid queen is reported for the first time in the ant genus Pheidole Westwood, 1839. Initially being investigated as a mermithergate, its true reproductive nature was finally proven after several years of searching for fresh specimens for dissection and imaging. Two possibilities remain unresolved regarding the reproductive strategy seen in the Philippine local populations of P. aglae: (1) that they are secondary reproductives; or (2) winged queens have been eliminated from the Philippine population...

Review of ants from the genus Polyrhachis Smith (Hymenoptera: Formicidae: Formicinae) in Hong Kong and Macau, with notes on their natural history

&
Polyrhachis is one of the most taxonomically and ecologically diverse ant genera in the world. Limited knowledge is, however, available on the species encountered within continental South East Asia, contrasting with the extensive studies conducted on African and Indo-Australian species. Here a contribution of Polyrhachis species from Hong Kong and Macau based on specimens collected in the past 30 years, with addition of material from other southeast Chinese provinces is provided. Additionally, new nest collections...

Thelytokous parthenogenesis by dealate queens in the myrmicine ant Monomorium hiten distributed in Nansei Islands, western Japan, with description of the male

, Shogo Makita, Hirotaka Nakao, Ryota Hosokawa, Tomonori Kikuchi & Seiki Yamane
Thelytokous reproduction by dealate queens in Monomorium hiten Terayama, 1996, collected from four islands of the Nansei Islands (Okinawa Prefecture, Japan) was confirmed in the field and laboratory. Dissection revealed that all dealate queens (N = 38) found in nine field collected colonies were uninseminated. Orphan colonies reared in the laboratory produced alate queens and they laid eggs from which workers or alate queens emerged. Alate queens reared in isolation produced nanitic workers without food...

Difference in leaf herbivory between two plant-ant taxa associating with a myrmecophytic species, Macaranga lamellata

, &
Macaranga lamellata (Euphorbiaceae) is a myrmecophytic species that is protected against herbivorous insects by two plant-ant taxa, Colobopsis macarangae (Formicinae) and Crematogaster spp. (Myrmicinae). Although a single M. lamellata tree houses one plant-ant colony of either of the two taxa, both coexist in a population of M. lamellata in a Bornean rainforest. To elucidate the extent of herbivory damage upon M. lamellata trees associated with Colobopsis relative to trees associated with Crematogaster, we counted the...

Nest structure of the bark-digging ant Rhopalomastix (Formicidae, Myrmicinae) and notes on its mutualistic associations with diaspidids in a Thai mango plantation

Gordon Yong, & Christian Peeters
Rhopalomastix is a bark digger ant that nests in the bark of living trees. The ants share a mutualistic relationship with diaspidids (armoured scale insects), housing them in their nest tunnels in the bark of a tree. Two colonies of Rhopalomastix sp. were sampled from two cultivars of mango trees in a mango plantation in Thailand. The architecture of the nest was mapped out and the respective resident diaspidid partners collected. Rhopalomastix built two different...

First records of Cardiocondyla ants from Myanmar

Jürgen Heinze, Andreas Trindl, Bernhard Seifert, & Win Maung
Numerous species of the diverse ant genus Cardiocondyla have been reported from countries in Southeast Asia, but as yet nothing has been known about their presence in Myanmar. A short, preliminary survey documents the occurrence of at least five species of Cardiocondyla in anthropogenically disturbed areas, such as gardens and parks. The species most commonly sampled has been determined as C. tjibodana, other specimens as C. parvinoda, C. obscurior, C. itsukii and one or two...

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,...
