Peruvian Andes [South America]
Subfamily Oxaeinae Ashmead
[Family Andrenidae]
This subfamily ranges from USA to Argentina and due to drastic differences in larvae and adults from other Andrenidae that Oaeinae has retained the status of a separate family for long. Oxaeinae fell within the Andrenidae in the phylogenetic analysis by Alexander & Michener (1995) as well as in the earlier studies of Michener (1944), Rozen (1993, 1994). Graf (1972) strongly supported placement of Oxaeinae in the Andrenidae based upon the paramandibular process of the hypostoma fused with clypeus, closing the mandibular sockets. A character also noticed in Panurginae by him.
Male genitalia and hidden sterna were studied by Popov (1941), Moure & Seabra (1962), Moure & Urban (1963) and, Hurd & Linsley (1976). Roberts (1973), Hurd & Linsley (1976) and Rozen (1993, 1994) are some of the important references with regard to nests and immatures.
