Alycaeus gibbosulus Stoliczka, 1872

Alycaeus gibbosulus Stoliczka, 1872: 268-269, pl. 10, fig. 14.

Alycaeus chaperi de Morgan, 1885a: 70.

Alycaeus (Orthalycaeus) gibbosulus - Möllendorff 1891: 342.

Alycaeus (Alycaeus) gibbosulus - Kobelt 1902: 344.

Alycaeus gibbosulus - Berry 1963: 17, pl. 4, fig. 25; Foon and Liew 2017: 38-41, figs 7F, G, 17, 31E.

Dioryx pyramidalis - Habe 1965: 111-112, pl. 2, figs 3, 4.

Type locality.

"Penang island" (from the title).

Material examined.

Penang, coll. Dr. Stoliczka, NZSI M.24998 (1 syntype); Perak, Kwala Kangsar ex coll. Grübauer, NHMW 36649 (7 shells, other 10 shells are A. conformis : NHMW 111541).

Remarks.

Shell sculpture as in A. conformis . The types of A. chaperi were not examined by us. We follow Möllendorff (1886, 1891) and Foon and Liew (2017) in treating it as a synonym of A. gibbosulus .

Habe’s (1965) record of this species from "Khao Chong, Trang Province, peninsular Thailand" almost certainly refers to Alycaeus gibbosulus .
