Hoplitis producta interior Michener, 1947


Scientific Name: Hoplitis producta interior Michener, 1947

Common Name: Produced Small-Mason


Hoplitis (Alcidamea) producta interior Michener, 1947: 286 [♂, ♀].

     Holotype ♂. USA, Colorado, Poncha Pass, 20 June 1933, by W. Steele [AMNH].


Taxonomic notes: Michener (1947: 289) indicated that the typical subspecies was found in the United States and southern Canada into the foothills east of the Rocky Mountains, though replaced by H. p. interior Michener, 1947 in the mountains. He also discussed intermediates between the two forms. This it is possible that H. p. interior just represents a variable form of H. p. producta, while H. p. subgracils, with a distinct DNA barcode BIN, may represent a valid taxon.

DNA Barcode Index Number (BIN): BOLD:AEX9850 (?)

The BIN assigned to this taxon is unique from the typical form (BOLD:AAA7118) and includes material from BC, Oregon, and Montana. As material has also been identified as H. p. subgracilis Michener, 1947 in BOLD, it is possible that the taxonomy of these subspecies should be re-examined.

Distribtuion in Canada: Michener 1947 [AB].

Body length: ♀ 7-7.5 mm ♂ 6 -7.5 mm
