Cremnomegachile

Taxonomy

Family: Megachilidae
Subfamily: Megachilinae
Tribe: Megachilini
Genus: Cremnomegachile Gonzalez & Engel, 2019
Subgenus: none
Common name: none

Overview

Cremnomegachile are elongate bees with shiny black integument, aside from their brownish legs, mandibles, and antennae (Benoist 1962). They have primarily white hair on their body and apical bands of hair on the terga (Benoist 1962). Their body length ranges from 8.5–12 mm (Benoist 1962). The subgenus gets its name from the Greek word “kremnos,” which means “overhanging wall,” referring to the projected anterior face of the scutum, and “chile,” which means “tooth” (Gonzalez et al. 2019).

Diagnostic characteristics

(modified from Gonzalez et al. 2019)

May be confused with

Cremnomegachile is similar to Stenomegachile in their elongate, shiny mandibles, the long labrum, and the toothed hypostomal area of the female and the bilobed preapical carina of the male. The projected anterior part of the scutum of Cremnomegachile can be used to separate the two genera. In addition, females can be differentiated by the shape of the labrum, which is triangular in Cremnomegachile and parallel-sided in Stenomegachile. Males also differ from each other in the number of mandibular teeth, three in Cremnomegachile and four in Stenomegachile.
