Two new species and a new record of the ant genus Meranoplus Smith, 1853 (Hymenoptera, Formicidae, Myrmicinae) from Thailand.

ABSTRACT: Meranoplus Smith, 1853 is distributed in the Old World tropics, from Africa, Asia, New Guinea to Australia. There are four species Meranoplusbicolor (Guérin-Méneville, 1844), M.castaneus Smith, 1857, M.laeviventris Emery, 1889, and M.mucronatus Smith, 1857 previously recorded from Thailand. In the present paper, two new species of the genus, M.siamensis Yodprasit & Jaitrong, sp. nov. and M.tanomtongi Yodprasit & Jaitrong, sp. nov., are described based on the worker caste. Additionally, M.malaysianus Schödl, 1998 is recorded for the first time for Thailand. A key to the Oriental and Indo-Australian species, based on the worker caste, is provided. The new species and the new record were found to nest in soil.

Project description:Stenamma is a cryptic "leaf-litter" ant genus that occurs in mesic forest habitats throughout the Holarctic region, Central America, and part of northwestern South America (Colombia and Ecuador). The genus was thought to be restricted primarily to the temperate zone, but recent collecting efforts have uncovered a large radiation of Neotropical forms, which rival the Holarctic species in terms of morphological and behavioral diversity. By inferring a broad-scale molecular phylogeny of Stenamma, Branstetter (2012) showed that all Neotropical species belong to a diverse Middle American clade (MAC), and that this clade is sister to an almost completely geographically separated Holarctic clade (HOC). Here, the Middle American clade of Stenamma is revised to recognize 40 species, of which 33 are described as new. Included in the revision are a key to species based on the worker caste, and for each species where possible, descriptions and images of workers and queens, images of males, information on geographic distribution, descriptions of intraspecific variation, and notes on natural history. Several species groups are defined, but the majority of species remain unassigned due to a lack of diagnostic morphological character states for most molecular clades. The following species are redescribed: Stenamma alas Longino, Stenamma diversum Mann, Stenamma expolitum Smith, Stenamma felixi Mann, Stenamma huachucanum Smith, Stenamma manni Wheeler, and Stenamma schmidti Menozzi. The following are described as new: Stenamma andersoni sp. n., Stenamma atribellum sp. n., Stenamma brujita sp. n., Stenamma callipygium sp. n., Stenamma catracho sp. n., Stenamma connectum sp. n., Stenamma crypticum sp. n., Stenamma cusuco sp. n., Stenamma excisum sp. n., Stenamma expolitico sp. n., Stenamma hojarasca sp. n., Stenamma ignotum sp. n., Stenamma lagunum sp. n., Stenamma llama sp. n., Stenamma leptospinum sp. n., Stenamma lobinodus sp. n., Stenamma longinoi sp. n., Stenamma maximon sp. n., Stenamma megamanni sp. n., Stenamma monstrosum sp. n., Stenamma muralla sp. n., Stenamma nanozoi sp. n., Stenamma nonotch sp. n., Stenamma ochrocnemis sp. n., Stenamma pelophilum sp. n., Stenamma picopicucha sp. n., Stenamma saenzae sp. n., Stenamma sandinista sp. n., Stenamma stictosomum sp. n., Stenamma tiburon sp. n., Stenamma tico sp. n., Stenamma vexator sp. n., and Stenamma zelum sp. n. Although many of the newly defined species consist of challenging species complexes, this study establishes a robust baseline that will guide future work on the systematics of MAC Stenamma. The total global diversity of Stenamma now includes 84 extant species.

Project description:The fauna of the purely Australian formicine ant genus Melophorus (Hymenoptera: Formicidae) is revised. This project involved integrated morphological and molecular taxonomy using one mitochondrial gene (COI) and four nuclear genes (AA, H3, LR and Wg). Seven major clades were identified and are here designated as the M. aeneovirens, M. anderseni, M. biroi, M. fulvihirtus, M. ludius, M. majeri and M. potteri species-groups. Within these clades, smaller complexes of similar species were also identified and designated species-complexes. The M. ludius species-group was identified purely on molecular grounds, as the morphology of its members is indistinguishable from typical members of the M. biroi species-complex within the M. biroi species-group. Most species-complexes sampled were also found to be monophyletic. Sequencing generally supported monophyly in taxa sampled but some species of the M. fieldi complex and M. biroi were not monophyletic and the implications arising from this are discussed in this monograph. Based on morphology, ninety-three species are recognized, 73 described as new. A further new species (here called 'Species K' [TERC Collection]) is noted in the taxonomic list, but is not described in this work. One species is removed from Melophorus: M. scipio Forel is here placed provisionally in Prolasius. Six species and five subspecies pass into synonymy. Of the full species, M. constans Santschi, M. iridescens (Emery) and M. insularis Wheeler are synonymized under M. aeneovirens (Lowne), M. pillipes Santschi is synonymized under M. turneri Forel, M. marius Forel is synonymized under M. biroi Forel, and M. omniparens Forel is synonymized under M. wheeleri Forel. Of the subspecies, M. iridescens fraudatrix and M. iridescens froggatti Forel are synonymized under M. aeneovirens (Lowne), M. turneri aesopus Forel and M. turneri candidus Santschi are synonymized under M. turneri Forel and M. fieldi propinqua Viehmeyer is synonymized under M. biroi. Camponotus cowlei Froggatt is reinstated as a junior synonym of Melophorus bagoti Lubbock. In addition, the subspecies M. fieldi major Forel, M. ludius sulla Forel and M. turneri perthensis Forel are raised to species. A key to workers of the genus is supplied. A lectotype is designated for M. curtus Forel, M. sulla, and M. turneri.
