Genus: Lophanthedon Gonzalez and Engel, 2012
Common name: none
Lophanthedon are black bees with reddish pubescence. They range in body length from 12–15 mm (Gonzalez and Engel 2012). Previously considered a subgenus of Megachile, Lophanthedon was elevated to genus status by Gonzalez et al. (2019).
(modified from Gonzalez and Engel 2012)
Female Lophanthedon are likely to be confused with Pseudomegachile (Largella) due to the similar characteristics of the clypeus, including the shape and longitudinal carina (Gonzalez and Engel 2012). Female Lophanthedon are also likely to be confused with Callomegachile due to the shiny and roughened mandible (Gonzalez and Engel 2012). Lophanthedon can be differentiated from Pseudomegachile (Largella) and Callomegachile based on the outer ridge of the mandible extending beyond the base of the mandible, the crenulate distal margin on the clypeus, and the lamellate distal margin on T6 (Gonzalez and Engel 2012).
Although there is limited research available on Lophanthedon nesting biology, they are known to be stem-nesting bees and have been observed nesting in trap nests (Inoka et al. 2006).
There are no known invasives.
Lophanthedon are found in Southeast Asia (Ascher et al. 2016b). They have been recorded in Borneo, Cambodia, southern China, India, Malaysia, Sri Lanka, Thailand, and Vietnam (Bambaradeniya 2006; Ascher et al. 2016b; Shankar et al. 2017).
