The Southeast Asian species of the Aenictus ceylonicus group are revised to include twenty-three species (4 named and 19 new species): Aenictus appressipilosus sp. n., A. baliensis sp. n., A. brevipodus sp. n., A. concavus sp. n., A. cylindripetiolus sp. n., A. eguchii sp. n., A. formosensis Forel, 1913 stat. n., A. fuchuanensis Zhou, 2001, A. gonioccipus sp. n., A. itoi sp. n., A. jawadwipa sp. n., A. khaoyaiensis sp. n., A. lifuiae Terayama, 1984, A. longicephalus sp. n., A. maneerati sp. n., A. minipetiolus sp. n., A. pilosus sp. n., A. pinkaewi sp. n., A. sundalandensis sp. n., A. thailandianus Terayama & Kubota, 1993, A. watanasiti sp. n., A. wilaiae sp. n., and A. wiwatwitayai sp. n. Aenictus ceylonicus var. formosensis Forel is removed from synonymy with A. ceylonicus and raised to full species. Lectotype and paralectotypes are designated for A. ceylonicus. Redescriptions of Aenictus ceylonicus (Mayr, 1866) (India and Sri Lanka) and A. doryloides Wilson, 1964 (India) are provided. The queen of A. cylindripetiolus is described. A key to the Southeast Asian species of the group is given based on the worker caste. Most of the Southeast Asian species of this species group have more or less limited distribution ranges. This may be due to the poor dispersal ability generally seen among the Aenictus species, in which the propagule (reproductive unit) is an apterous queen plus accompanying workers.10aAenictinae10aAenictus10aceylonicus species-group10aFormicidae1 aJaitrong, W.1 aS., Yamane uhttps://singaporeants.myspecies.info/node/82101716nas a2200193 4500008004100000245014700041210006900188260000900257300001200266490000800278520106700286653001501353653001301368653002601381653003301407100001701440700001501457856005001472 2012 eng d00aReview of the Southeast Asian species of the Aenictus javanus and Aenictus philippinensis species groups (Hymenoptera, Formicidae, Aenictinae)0 aReview of the Southeast Asian species of the Aenictus javanus an c2012 a49 - 780 v1933 aThe Southeast Asian species of the Aenictus javanus and Aenictus philippinensis groups are revised. Six species (four named and two new species) of the Aenictus javanus group occurring in this area are: A. doydeei Jaitrong & Yamane, 2011, A. duengkaei Jaitrong & Yamane, sp. n., A. javanus Emery, 1896, A. longinodus Jaitrong & Yamane, sp. n., A. nishimurai Terayama & Kubota, 1993, and A. piercei Wheeler & Chapman, 1930. Four species (three named and one new species) are recognized in the Aenictus philippinensis group: A. pangantihoni Zettel & Sorger, 2010, A. philippinensis Chapman, 1963, A. punctatus Jaitrong & Yamane, sp. n., and A. rabori Chapman, 1963. A. piercei is removed from the members of the A. pierce group sensu Jaitrong and Yamane (2011) and transferred to the A. javanus group. Lectotypes and paralectotypes are designated for A. piercei and A. rabori. Size variation occurs among individuals from single colonies of the A. javanus group, while the workers in the A. philippinensis group are clearly monomorphic.10aAenictinae10aAenictus10ajavanus species-group10aphilippinensis species-group1 aJaitrong, W.1 aS., Yamane uhttps://singaporeants.myspecies.info/node/82201608nas a2200205 4500008004100000245011100041210006900152260000900221300001200230490000900242520097000251653001501221653001301236653003701249653001501286653001901301100001701320700001501337856005001352 2012 eng d00aRevision of the Aenictus minutulus species group (Hymenoptera: Formicidae: Aenictinae) from Southeast Asia0 aRevision of the Aenictus minutulus species group Hymenoptera For c2012 a29 - 440 v34263 aThe genus Aenictus is a diverse group of army ants in the Old World tropics and subtropics. The worker-based Aenictus piercei species group of Jaitrong and Yamane (2011) is redefined and renamed here as the Aenictus minutulus group. Aenictus piercei Wheeler et Chapman, 1930 and A. lifuiae Terayama, 1984 are removed from this group; the former is moved to the A. javanus group and the latter to the A. ceylonicus group. The Southeast Asian species of the group are revised to include six species: Aenictus changmaianus Terayama et Kubota, 1993, Aenictus sp.56 of WJT, A. minimus sp. nov., A.

minutulus Terayama et Yamane, 1989, A. peguensis Emery, 1895 and A. subterraneus sp. nov. Aenictus changmaianus, A. minimus and A. peguensis are probably restricted to the seasonal forest located northward from the Isthmus of Kra, while A. minutulus, A. subterraneus and Aenictus sp.56 of WJT are obviously Sundaland species inhabiting the perhumid evergreen rainforest.10aAenictinae10aAenictus10aAenictus minutulus species-group10aFormicidae10aSoutheast Asia1 aJaitrong, W.1 aS., Yamane uhttps://singaporeants.myspecies.info/node/82301970nas a2200145 4500008004100000245018700041210006900228260000900297300001100306490000900317520141600326100001701742700001501759856005001774 2011 eng d00aSynosis of Aenictus species groups and revision of A. currax and A. laeviceps groups in the Oriental, Indo-Australian, and Australiasian regions (Hymenoptera: Formicidae: Aenictinae)0 aSynosis of Aenictus species groups and revision of A currax and  c2011 a1 - 460 v31283 aTwelve species groups are established in the ant genus Aenictus of the eastern part of Oriental region, and Indo-Australian and Australasian regions, and the species of the Aenictus currax group and A. laeviceps group are revised.
