Abstract

In this study the taxonomy of the Pheidole pulchella species group is updated for the Afrotropical region and the new species P. klaman sp. nov. described. It is integrated into the existing taxonomic system by an updated identification key for the whole group and an update of the known distribution ranges of its members. High quality focus stacking images are provided, with X–ray micro–CT scanned digital 3D representations, of major and minor worker type specimens.

Taxonomy of the ant genus Pheidole Westwood (Hymenoptera: Formicidae) in the Afrotropical zoogeographic region: definition of species groups and systematic revision of the Pheidole pulchella group

GEORG. FISCHER, FRANCISCO GARCÍA, MARCELL K. PETERS (2012)

This paper is a starting point towards a much needed comprehensive taxonomic treatment of the genus Pheidole in theAfrotropical region. Despite its hyperdiversity, the taxonomy of this globally distributed ant genus is limited to importantrevisions for the New World and several Asian faunas. However, Pheidole of the Afrotropical zoogeographic region hasnever been revised. The most recent Afrotropical Pheidole species descriptions are fifty years old and many are consider-ably older. Identification keys are not available and many species descriptions are of limited diagnostic value. This callsfor a series of taxonomic revisions in order to resolve the complicated taxonomic situation for the complete AfrotropicalPheidole fauna. In this paper the following preliminary morphological species groups for the Afrotropical region are de-fined: P. aurivillii group, P. excellens group, P. megacephala group, P. nigeriensis group, and P. speculifera group. We also establish and revise the P. pulchella group, which currently contains eleven species, of which seven are new. The four spe-cies described prior to this study are: P. pulchella Santschi, P. dea Santschi, P. nimba Bernard, and P. batrachorum Wheelerstat. rev., which is removed from synonymy under P. dea and regains species status. The following new synonymy isproposed (senior synonym listed first): P. pulchella Santschi = P. pulchella achantella Santschi. The following seven spe-cies are described as new: P. christinae sp. n., P. darwini, sp. n., P. glabrella sp. n., P. heliosa sp. n., P. rebeccae sp. n., P. semidea sp. n. and P. setosa, sp. n. An illustrated key combining the minor and major worker subcastes is presented.

Pheidole Westwood, 1839 ( Hymenoptera , Formicidae ) of Madagascar – an introduction and a taxonomic revision of eleven species groups

Sebastian Salata, Brian Fisher (2020)

Abstract The present study represents an introduction to the revision of Pheidole Westwood, 1839 from Madagascar. Sixteen species groups are established, of which eleven are revised below, and illustrated identification keys to species groups and species of groups revised in this monograph are presented. Two species are raised to species level: Pheidole petax Forel, 1895 stat. nov., and P. scabrata Forel, 1895 stat. nov. We also redescribe worker castes and designate lectotypes for P. annemariae Forel, 1918, P. nemoralis Forel, 1892, P. petax Forel, 1895, P. ensifera Forel, 1897, P. longispinosa Forel, 1891, and P. scabrata Forel, 1895. The following 46 new species are described: Pheidole aelloea sp. nov., P. ala sp. nov., P. andapa sp. nov., P. ankerana sp. nov., P. avaratra sp. nov., P. bemarahaensis sp. nov., P. bemarivoensis sp. nov., P. binara sp. nov., P. boribora sp. nov., P. brevipilosa sp. nov., P. curvistriata sp. nov., P. diakritos sp. nov., P. ehazoara sp. nov., P. ferruginea sp. nov., P. fisaka sp. nov., P. fitarata sp. nov., P. glabra sp. nov., P. goavana sp. nov., P. lamperos sp. nov., P. longipilosa sp. nov., P. lutea sp. nov., P. madinika sp. nov., P. mahaboensis sp. nov., P. maizina sp. nov., P. makaensis sp. nov., P. makirovana sp. nov., P. manantenensis sp. nov., P. mantadia sp. nov., P. marieannae sp. nov., P. masoala sp. nov., P. mavesatra sp. nov., P. miramila sp. nov., P. moramanaensis sp. nov., P. navoatrensis sp. nov., P. ocypodea sp. nov., P. parviocula sp. nov., P. podargea sp. nov., P. praegrandis sp. nov., P. ranohirensis sp. nov., P. rugocephala sp. nov., P. rugofitarata sp. nov., P. typhlos sp. nov., P. vatovavensis sp. nov., P. voasara sp. nov., P. vohemarensis sp. nov., and P. zavamanira sp. nov. At present, there are 69 valid species and subspecies of Pheidole known from Madagascar, but this number is expected to increase significantly with upcoming taxonomic revisions of the species groups not revised in this study.
