Diagnosis

This species can be recognized based on the dense R1 ribs, the R3 with widely-spaced ribs, the thick peristome (protruding inner peristome) and that the outer peristome is not reflected abruptly towards umbilicus (i.e., it does not form a sharp angle below the umbilicus).

Type material examined

MYANMAR • 4 syntypes of A. graphicus ( Fig. 25A–E); Moditoung, Tongoop Pass, Arakan; NHMUK 1906.4 About NHMUK .4.42 • 2 syntypes of A. difficilis ( Fig. 25F–J); Shan States; Fedden leg.; NHMUK 1906.5 About NHMUK .5.22 .

Type localities

“in montibus Arakanensibus provinciam Burmanam Pegu ad Arakan secernentibus” ( A. graphicus ); “ Shan Hills” ( A. difficilis ).

Remarks

Alycaeus graphicus and A. difficilis are identical in all shell traits (except minor difference in rib density), therefore they are treated as synonyms. The ribs of this species are more widely-spaced than those of C. major , although no other differences were found.
