Wien 104 B 203 - 338 Wien, März 2003 The ant genus Cardiocondyla (Inserta: Hymenoptera: Formicidae) - a taxonomic revision of the G elegans, G bulgarica, G batesii, C. nuda, G shuckardi, G stambuloffii, G wroughtonii, G emeryj, and G minutior species groups B. Seifert* Abstract A taxonomic revision of all holarctic species groups of the ant genus Cardiocondyla is given, including all worldwide species groups, with at least one tramp species. General aspects of Cardiocondyla biology such as habitat selection, nest construction, behaviour, the ergatoid male syndrome, and gyne polymorphism are treated. 48 species are recognized, 20 of which are described as new: Cardiocondyla bicoronata sp.n. (Israel, Jordan, United Arab Emirates, Yemen, Turkestan), C brachyceps sp.n. (E Turkey, Iran, Afghanistan), C. breviscapus sp.n. (India), C. gallilaeica sp.n. (Israel), C. goa sp.n. (India), C. israelica sp.n. (Egypt, Israel), C. littoralis sp.n. (S Kazakhstan), C. longiceps sp.n. (Yemen), C. melano sp.n. (Yemen), C. nana sp.n. (Brunei), C. opaca sp.n. (India), C. opistopsis sp.n. (Kuwait), C. paranuda sp.n. (Tunisia), C. persiana sp.n. (Iran, Israel), C. rugulosa sp.n. (Yemen), C. semirubra sp.n. (Asia Minor), C. shagrinata sp.n. (India), C. tenuifrons sp.n. (Jordan), C. tibetana sp.n. (Tibet, Tarim Basin) and C unicalis sp.n. (Iran). Sixteen taxa are newly synonymized: Cardiocondyla bulgarica FOREL, 1892 (= C. elegans var. eleonorae FOREL, 1911, syn.n.), C. elegans EMERY, 1869 (= C. dalmatica SOUDEK, 1925, syn.n., = C. provincialis BERNARD, 1956, syn.n.), C.fajumensis FOREL, 1913, stat.n. (= C. schatzmayri FINZI, 1936, syn.n., = C. nilotica WEBER, 1952, syn.n.), C. mauritanica FOREL, 1890 (= C. ectopia SNELLING, 1974, syn.n.), C. minutior FOREL 1899, stat.rev. (= C. tsukuyomi TERAYAMA, 1999, syn.n.), C. nigra FOREL, 1905 (= C. elegans var. torretassoi FINZI, 1936, syn.n.), C. obscurior WHEELER, 1929, stat. n. (= C. bicolor DONISTHORPE, 1930, syn.n.), C. shuckardi FOREL, 1891 (= C. shuckardoides FOREL, 1895, syn.), C. stambuloffii FOREL, 1892 (= C. bogdanovi RUZSKY, 1905; syn.n.), C. venustula WHEELER, 1908 (= C globinodis STITZ, 1923, syn.n., = C. badonei ARNOLD, 1926, syn.n.), C. wroughtonii (FOREL, 1890) (= C. wroughtonii ssp. quadraticeps FOREL, 1912, syn., = C. longispina KARAVAJEV, 1935, syn.n., = C. yamauchii TERAYAMA, 1999, syn.n.). Five taxa are elevated to species rank, and the status of two controversial taxa is revised. Nine names are listed under "Incertae Sedis". Each species is described based upon workers and gynes, as far as either caste is known, and a detailed morphometry by high-resolution steromicroscopy is provided. Each species is depicted in three or four standard viewing positions preferentially on the basis of type material. Key words: Cardiocondyla, taxonomic revision, Holarctic, tramp species, ergatoid males, gyne polymor- phism, new species, new synonymy, new status, behaviour, nest, habitat. Zusammenfassung Eine taxonomische Revision der holarktischen Vertreter der Ameisengattung Cardiocondyla sowie aller kosmopolitischen Artengruppen, in denen mindestens eine Tramp-Spezies vorkommt, wird präsentiert. Allgemeine Aspekte der Cardiocondyla-B\o\ogie wie Habitatwahl, Nistweise, Verhalten, das Syndrom der ergatoiden Männchen und Gynenpolymorphismus werden behandelt. Es werden 48 Arten unterschieden, von denen 20 als neu beschrieben werden: Cardiocondyla bicoronata sp.n. (Israel, Jordan, United Arab Emirates, Yemen, Turkestan), C. brachyceps sp.n. (E Turkey, Iran, Afghanistan), C. breviscapus sp.n. (India), C. gallilaeica sp.n. (Israel), C. goa sp.n. (India), C. israelica sp.n. (Egypt, Israel), C. littoralis sp.n. * Dr. Bernhard Seifert, Staatliches Museum für Naturkunde Görlitz, PSF 300154, D-02806 Görlitz, Germany ©Naturhistorisches Museum Wien, download unter www.biologiezentrum.at 204 Annalen des Naturhistorischen Museums in Wien 104 B (S Kazakhstan), C. longiceps sp.n.

Fünf Taxa erfuhren eine Rangerhöhung und der Status zweier umstrittener Taxa wird revidiert. Neun Namen werden unter 'Incertae Sedis' aufgelistet. Jede Art wird anhand von Arbeitern und Gynen, soweit diese bekannt sind, beschrieben, durch eine detailierte Morphometrie mittels Hochleistungsstereomikroskopie vorgestellt und in drei oder vier Standardansichten abgebildet, wobei Typenmaterial bevorzugt dargestellt ist.
