a μ-CT-based 3D reconstruction of internal reproductive organs viewed from ventral. Notice that the seminal vesicle (sv) is only developed on the right side. b Histological cross section of K. biedouwense male postabdomen, approximately through abdominal segment VI; bar = 200 μm. c Close-up of testicular follicles from horizontal section through K. biedouwense male postabdomen, bar = 20 μm. d Cross section through K. biedouwense at the location of the seminal vesicle, bar = 200 μm. e Close-up of seminal vesicle, bar = 100 μm. ag – accessory gland, de – ductus ejaculatorius, dv – dorsal vessel, fb – fat body, g – gut, ga – ganglion, mp – Malpighi vesicles, ps – peritoneal sheath, sv – seminal vesicle, sp – spermatozoa, te – testis, tf – testicular follicle, vd – vas deferens, ve – vas efferens, vn – ventral nerve cord
