blind-ended branch of the pedunculus epiphallar caecum – epiphallus caecum epiphallus – epiphallus; defined by as the organ manufacturing the spermatophore...

The reproductive system of Arion vulgaris is important for species identification: at = atrium; bc = bursa copulatrix; ep = epiphallus; ov = oviduct...

longer rotating. The genitalia take some minutes to engage and evert, the epiphallus (spermatophore producing organ) connecting to the bursa trunk of the other...

species. The clearest character is the structure at the entrance to the epiphallus. A 30–40 mm. long (exceptionally up to 50 mm) roundback slug. In colour...

deferens and the epiphallus. Arion slugs lack a penis. The vas deferens connects the spermoviduct to the epiphallus. The epiphallus then opens to the...

Tandonia, the retractor penis inserts at the boundary between the penis and epiphallus. In stallions, the retractor penis muscle is relatively underdeveloped...

or slightly shorter, getting slightly wider near insertion at atrium, epiphallus longer than vas deferens, vagina longer and wider than spermatheca duct...

Reproductive system: The penis is rounded, and half as long as the epiphallus. The epiphallus is slightly widened and truncated (as if cut off) at its end....

spermatophore is formed in the epiphallus (between vas deferens and penis) and the flagellum (continuation of the epiphallus proximally from the vas deferens...

or plate-like. Genitalia: the penis is present only in some species, epiphallus is present in nearly all of them. Male copulatory organs are generally...

towards the distal part which is subcylindrical again. Transition to the epiphallus with a kink, thereafter gradually tapering; twisted. Vas deferens is adhering...

11 mm in width. Reproductive system: Penis rounded, far wider than epiphallus, epiphallus elongate with peaky end, vas deferens opening symmetrically, spermatheca...

penis is usually short, the epiphallus is long. The retractor penis inserts at the boundary between the penis and epiphallus. The vas deferens of specific...

diverticulum, bursa duct, bursa retractor muscle, bursa copulatrix. On the top right: epiphallus. Center: vas deferens. Lower right: free oviduct, spermoviduct....

Entire – With even, unbroken edges, as the aperture of some shells. Epiphallus – A portion of the vas deferens which becomes modified into a tube-like...

bursa copulatrix opens near the end of the epiphallus; the oviduct is long with two bends; the epiphallus blends imperceptibly with the vas deferens;...

penis and epiphallus form a single long cylindrical organ: penis with a swelling anteriorly, inside with a richly ornamented papilla, epiphallus obviously...

7 mm. Reproductive system: The penis is subdivided in two sections. The epiphallus is shorter and slightly widening at its posterior end. The vas deferens...

approximately as long as the epiphallus. The vas deferens opening is clearly asymmetrically at the posterior end of epiphallus. There is a small simple papilla...

the penial complex with distinct penis, which is continuous with the epiphallus, epiphallic caecum (a flagellum and an appendix), unbranched gametolytic...
