Two phylogenetic relationships based on morphology for the subgenera, species groups and for the all species of Bradyporus s. l. are proposed. A new diagram shows together the relationships and the schematized distributions of the taxa, Geographical Network Relationship, is proposed. A synonymic checklist of the known species of Bradyporus s. l. is given. Taxonomical changes, the doubtful and uncertain taxa names are discussed. Callimenus Fischer von Waldheim, 1830 is proposed as a subgenus of Bradyporus Charpentier, 1825. Four species groups, B. oniscus sp. group, B. macrogaster sp. group, B. dilatatus sp. group and B. latipes sp. group, are separated. Callimenus macrogaster pancici Brunner, 1882 is synonymized with Bradyporus (Callimenus) macrogaster longicollis (Fieber, 1853). Neotypes for B. (s. str.) dasypus (Illiger, 1800) and B. (Callimenus) macrogaster macrogaster (Lefebvre, 1831) are designated. Five new species, Bradyporus (Callimenus) avanos sp. n., B. (Callimenus) sureyai sp. n., B. (Callimenus) conophallus sp. n., B. (Callimenus) toros sp. n. and B. (Callimenus) karabagi sp. n. are described. Bradyporus (Callimenus) latipes (Stal, 1875) is recorded from Turkey for the first time. The species Schulmeisteri schulmeisteri Harz, 1992 is excluded from the subfamily Bradyporinae. All previous records of Bradyporinae species in Turkey with full synonymic list of each species are given. The previous misidentifications are determined and then the distribution of each species is adjusted. The characters used the separation of the taxa are briefly discussed. The titillator for Turkish species and the basal projecting of ventral valve of ovipositor are used for the first time. Descriptions and redescriptions of the studied Bradyporus species are given. Keys to tribes, subgenera, species groups and Turkish species of Bradyporus are provided. In addition 157 original figures including a distributional map are provided.

Twenty-six morphological characters obtained from the literature were analyzed; 16 of these characters clearly exhibited delimited states but only four of them were unique for each species. The status of every species of the genus was supported by geometric morphometrics of the head (front view, dorsal view and metasomal tergum 1) and by the presence of unique character states for each species. Phylogenetic analyses included nest and genitalia characters. Character reassessment provided a less resolved tree to that previously published. Including polymorphic characters did not improve tree resolution or clade support, while applying the conjunction test offered a more resolved and better supported tree. The study revealed the importance of analyzing variation in taxonomic and phylogenetic studies within and between species. A new key to species and a phylogenetic hypothesis are offered.

It is unique among all North American species of its genus in having the mesepimeral and metepimeral stripes distinctly paler than the mesepisternal stripes in combination with yellow bands on S3-8 that are interrupted middorsally by the carina.
