FIGURE 2 in Morphological and molecular distinction of two Fridericia species (Clitellata, Enchytraeidae) having same spermatheca type

FIGURE 2. Micrographs of Fridericia ventrochaetosa sp. n. A. End of oesophageal appendage with multiple branches (arrows). B. Male copulatory organs (arrows); clitellar gland cells visible laterally and ventrally posterior to copulatory organs. C. Midgut pars tumida (arrows) in XXXI–XXXIII (holotype). D. Chylus cells in XIII–XIV. E. Male copulatory organs, ventral view, holotype. Strong bursal muscle marked with arrow. Asterisk: region between the two organs without clitellar glands. F– G. Bursal slits (marked with arrow in G). H. Male copulatory organ, lateral view (paratype P.112.1.2, No. 2219=DNA 978). I,J. Sperm funnels (paratype P.112.1.2, No. 2219=DNA 978). A, F, G, I in vivo, B, D, H, J fixed, stained, C, E fixed, not stained. Scale bars 50 µm.
