Material examined. New South Wales, Australia: AM C391188 (one shell measured, photographed; live animal photographed; one specimen dissected, radula examined), Yarramundi Regional Park, off Hawkesbury Rd. (33º40' S, 150º39' E), 21 Jan. 2001, S.A. Clark, M. Shea, A.C. Miller, L. Puslednik GoogleMaps .

Description. External morphology: Shell ( Figures 19A View FIGURE 19 , 20A View FIGURE 20 , 21A View FIGURE 21 ) reduced, 3.1 whorls, light orangebrown, spire and apex flattened; shape and sculpture as for genus. Animal ( Figure 6J View FIGURE 6 ) cream with dark grey markings. Mantle laps moderately long, wide at base, tapering to a blunt point, not fused, uniform in colour. Right mantle lobe moderately large; left and median lobes large, fused to form small lobe over head. Caudal apparatus as for genus; caudal horn moderately small.

Mantle cavity ( Figure 10C View FIGURE 10 ): As for genus. Mantle with pigmentation of black spots.

Digestive system: As for genus.

Genital system ( Figures 13I View FIGURE 13 , 18A View FIGURE 18 ): As for genus. Carrefour embedded in albumen gland, talon free. Free oviduct with longitudinal pilasters present in oviduct and deep transverse pilasters in capsular gland. Penis moderately long; epiphallus enters penis through short verge, less than a quarter of penis length; penis internally covered in pustules. Penis retractor muscle attached to tip of epiphallic caecum. Epiphallus longer than penis, internally with longitudinal pilasters.

Radula ( Figure 17D–F View FIGURE 17 ): As for genus. Radular formula (45.17.1.17.45) × 130 rows.

Range and habitat. Stanisicarion freycineti is found in dry sclerophyll forest and occasionally rainforest from around Nowra, south of Wollongong, to the Kempsey Valley, New South Wales. There is also a record from Brunswick Heads near the New South Wales-Queensland border (AM C374677). Specimens are usually found under logs and other debris on the ground.

Remarks. Both Stanisicarion freycineti and S. virens have been observed to have very distinctive egg masses, shaped with spiralling grooves and coming to a point at the top (like a soft-serve ice-cream) (see Figure 6K View FIGURE 6 ). Most other Australian Helicarionidae appear have smooth spherical eggs (e.g., Mysticarion porrectus , C421841; Figure 6C View FIGURE 6 ). One unusual feature noted in S. freycineti was the presence of deep pilasters inside the capsular gland. These were absent in all other species, with the exception of Fastosarion superba . The capsular gland has been shown in the ariophantid Ariophanta ligulata ( Férussac, 1821) to form the final coating on eggs as they are being laid ( Dasen 1933). This soft coating then hardens into a capsule. It appears possible that deep pilasters in the capsular gland of S. freycineti may be responsible for the distinctive sculpture of the egg capsule.
