Homola ranunculus
Guinot & Richer de Forges, 1995
Female 41.4 × 38.1 mm,
New Caledonia
, stn CC1 (MNHN-B 19869).
Sternite 8 shows a relatively long median line, and the sterno-abdominal notch is not very deep. The spermatheca occupies about half of the suture 7/8. A wide membranous area, which belongs to sternite 7, is followed by a long slit along suture 7/8; another membranous area, belonging to sternite 8, is more internal and oblique inside the slit. The aperture is slit-like and concealed. The inner wall of the chamber is soft and slightly wrinkled; the external wall is not so flexible. The skeleton (

) shows the connections by interfingering, typical for homoloids.
