The myrmicine ant genus Stenamma Westwood is redefined and a new diagnosis of the worker caste is presented. Justified by both morphology and molecular data, two species are removed from Stenamma and transferred to the genus Lordomyrma Emery: L. bhutanensis (Baroni Urbani) comb. n. and L. sinensis (Ma, Xu, Makio & DuBois) comb. n. Based on compelling differences in morphology, a third species originally described in Stenamma is transferred to the genus Propodilobus gen. n.: P. pingorum (DuBois) comb. n. Molecular results also indicate that Stenamma, as newly defined here, is a monophyletic genus that forms a clade with Aphaenogaster Mayr and Messor Forel. Additional notes on the diversity and distributions of Stenamma, Lordomyrma, and Propodilobus are provided.

The first annotated checklist of the ants of Turkey is presented. A total of 306 valid names of species-group taxa (286 species, 20 subspecies) is recorded based on literature records and additional newly collected material carried out since 1998. Synonyms are included. New localities are added for some poorly known species. Four species (Tapinoma subboreale, Formica georgica, Formica lugubris and Lasius balcanicus) are reported for the first time and thirteen species (Bothriomyrmex atlantis, B. meridionalis, Tapinoma madeirense, Camponotus robustus, Formica fuscocinerea, F. gagatoides, Rossomyrmex minuchae, Messor barbarus, Monomorium glabrum, M. salomonis, Myrmica vandeli, Stenamma westwoodii and Tetramorium forte) are excluded from the list of Turkish ants.

Lordomyrma is recorded for the first time from India and mainland southeast Asia. The Japanese L. azumai is reviewedand six new worker-based species described: L. lakshmi (Kerala State, India); L. hmong (Lao Cai Province, Vietnam); L. diwata, L. emarginata and L. idianale (Mt Isarog, Luzon, Philippines) and L. limatula (Leyte, Philippines). Gynes are characterized for L. azumai, L. hmong and L. limatula. All taxa are diagnosed, illustrated, and their affinities discussed.
