The aculeata group, sensu Deeleman-Reinhold & Deeleman (1988: 231).
Diagnosis. The group can be distinguished by the following characters: hexagonal carapace, leg femora equipped with spines, psembolus distinctly longer than tegulum, psembolus with a median crest and acuminate apex (Deeleman-Reinhold & Deeleman 1988).
Composition. Eleven species are assigned to this species group: D. aculeata Kroneberg, 1875 (Central Asia, probably Iran, introduced to Croatia), D. afghana Denis, 1958 (Afghanistan), D. arabica Deeleman-Reinhold, 1988 (Oman), D. concinna L. Koch, 1878 (Azerbaijan), D. dushengi Lin, Chang et Li, 2020 (Kazakhstan and Xinjiang), D. dysderoides (Caporiacco, 1947) (Ethiopia), D. limitanea Dunin, 1985 (Turkmenistan), D. pamirica Dunin, 1992 (Tajikistan), D. pococki Dunin, 1985 (Iran and Turkmenistan), D. tartarica Kroneberg, 1875 (Central Asia) and D. zarudnyi Charitonov, 1956 (Central Asia and Afghanistan).
Comments. Deeleman-Reinhold & Deeleman (1988) did not examine D. pamirica and therefore this species was not assigned to any of the species groups proposed by them. D. pamirica is here considered a member of the aculeata group based on the proportions and the shape of its bulb: viz., psembolus significantly longer than tegulum, having a median crest and a pointed apex; see figs 7–9 in Dunin (1992).
