Genus Trichochloritis Pilsbry, 1891

Trichochloritis Pilsbry, 1891: 267.

Trichochloritis: Schileyko 2007: 2113-2114, fig. 2032 (partim).

Type species.

Helix breviseta L. Pfeiffer, 1862 by original designation.

Included species.

Helix breviseta L. Pfeiffer, 1862, Trachia penangensis Stoliczka, 1873.

Diagnosis.

Shell depressed globular, apex not sunken, hairs or hair scars cover the entire shell. Penis thickened, probably with penial verge (?) and a slender, relatively long penial caecum; epiphallus slender, shorter than penis; retractor muscle attached at the penis-epiphallus transition; flagellum short; vagina slender, shorter than penis; stalk of bursa copulatrix long, with thickened base and oval bursa (based on the drawings of Stoliczka 1873: plate 3, fig. 18 and Collinge 1903: plate 12, fig. 17.).

Remarks.

The anatomy of the genital organs of Helix (Trachia) malayana Möllendorff, 1887 (= Trichochloritis breviseta; see Maassen 2001) was described by Collinge (1903), and that of T. penangensis is known from Stoliczka (1873), here re-drawn and provided in Fig. 8 ( penangensis) and Fig. 9 ( breviseta). Both species possess a penial caecum, which is here considered as a diagnostic trait for the genus. Without knowing the full anatomy, it is uncertain how many of the hairy Chloritis -like species of continental Asia belong to this group.
