Family: Megachilidae
Subfamily: Megachilinae
Tribe: Megachilini
Genus: Rozenapis Gonzalez and Engel 2019
Common name: none


Bees in the genus Rozenapis have a black integument except for the terminal terga of the abdomen that are reddish (Gonzalez et al. 2019). They are somewhat sparsely covered in white and reddish hairs, with females having lateral patches of white hairs on their abdomen (Cockerell 1913; Gonzalez et al. 2019). Rozenapis range in body length from 12–15 mm (Gonzalez et al. 2019). The bees in this genus had previously been considered members of Megachile (Hackeriapis) prior to the description of Rozenapis by Gonzalez et al. (2019).

Diagnostic characteristics

(modified from Cockerell 1913; Prendergast 2018; Gonzalez et al. 2019)

May be confused with

Rozenapis share a significant range overlap and are similar in appearance to Hackeriapis, including both having reddish terminal terga (Gonzalez et al. 2019). Females can be differentiated by examining S1, as Rozenapis have a large midapical spine on S1 and Hackeriapis do not (Gonzalez et al. 2019). Male Rozenapis tarsal claws lack a basal tooth, unlike Hackeriapis which have a basal tooth on their tarsal claws (Gonzalez et al. 2019).

Host associations

Through observation and pollen analysis of nest provisions, Rozenapis has been associated with flowers of Fabaceae and with the genus Jacksonia in particular (Prendergast 2018). Additionally, they are known to collect nesting material from flowers of Banksia species (Proteaceae) (Prendergast 2018).

Nesting behavior

Rozenapis have been observed nesting in trap nests, and they likely nest in other pre-existing cavities (Prendergast 2018). They build their nests with masticated leaf material, resin, and material from Banksia plants, including parts of flowers and downy hairs collected from the plant (Prendergast 2018).


Rozenapis is monotypic; R. ignita is the only species in the genus (Gonzalez et al. 2019).

Known invasives

There are no known invasives.


Rozenapis is found only in Australia. (Prendergast 2018; Gonzalez et al. 2019).
