Name
Calocosmus janus Bates – Wikispecies link – Pensoft Profile
- Calocosmus holosericeus Gahan, 1889: 395, syn. n.
Diagnosis
This species is easily distinguished from all other Hispaniolan Hemilophini by the uniformly purplish-black elytra, black antennae without annulations, and pronounced elytral humeri. The only other species with mostly dark elytra are Calocosmus punctatus, Calocosmus semimarginatus, and Calocosmus nigripennis. Calocosmus punctatus is distinguished easily by having the antennae with basal annulations of gray pubescence on most antennomeres, the elytra with scattered fulvous regions, and having the elytral punctures far more dense and well defined than in Calocosmus janus. Calocosmus semimarginatus and Calocosmus nigripennis are easily distinguished by lacking humeral projections and by their small size (most specimens less than 8 mm long while most specimens of Calocosmus janus are greater than 10 mm long).
Notes
Calocosmus holosericeus Gahan is a new synonym of Calocosmus janus Bates. Photos of the holotypes show they are nearly identical, as are the original Latin descriptions for each. Calocosmus holosericeus was described from Hispaniola and Calocosmus janus was described from Cuba. The Dominican Republic and Hispaniola therefore represent new country and island records for Calocosmus janus.
