Fig. 6. Hectocotylus (left arm I) of Sepiola boletzkyi sp. nov., holotype, ♂, ESFM-CEP/1994-1. Abbreviations: a–d = suckerless stalks forming the copulatory apparatus proper (a = ventral-most, d = dorsal-most one, i.e. tubercle); * = lobe in the dorsal row of suckers, 1–11 = sequence of heteromorphous suckers in the dorsal row of distal part. A. Oral view; the arm is slightly tilted, with the tip towards the observer, in order to show details (lobe and small suckers 1–2), otherwise hidden by the four suckerless stalks of the copulatory apparatus. Basal part: only the two ventral suckers are visible, the dorsal one is missing as a result of damage. Copulatory apparatus: the tubercle (d) partially hides the lobe in the dorsal row (*). Distal part: the heteromorphous suckers in the dorsal row are 1–2 small, 3–8 enlarged, 9 small, 10–11 enlarged; the remaining suckers are regular; note that some suckers (2, 3 and 7) are displaced towards the centre of the arm, i.e., not aligned with the others of their same row; it is not known whether this is natural or caused by preservation. B. Inner-lateral view of copulatory apparatus; the lobe (*) forms a groove with the tubercle (d). C. Oblique inner-lateral view of copulatory apparatus; two barely visible longitudinal lines on the lobe (*) are likely fusion lines between adjacent stalks forming it. Scale bars = 1 mm.
