ZooBank: urn:lsid:zoobank.org:act:1D8C1D13-D199-4383-B769-21B3E93F63E1

TYPE GENUS: Lonchorhyncha Michener, 1989 .

DIAGNOSIS: This subtribe is unique among Lonchopriini for its greatly elongate head, the result of the malar space being about as long as the compound eye. The face is quite protrudent, with the frontoclypeal portion of the epistomal sulcus situated below the lower tangent of the compound eyes. The inner metatibial spur of the female is coarsely pectinate with about 10 branches. The male terminalia are quite distinctive and differ greatly from all other Lonchopriini and even from most New World Colletidae (vide Michener, 1989). The bees are of moderate size, about 11.5–13 mm in length. The genus and its sole species, Lonchorhyncha ecuadoria (Friese) , were described in detail by Michener (1989), and a more elaborate account of the genus is therefore not repeated here. The species is found in southern Colombia and Ecuador (Michener, 1989, 2007). This group may be more closely allied to Eulonchopriina or some features even suggest an association with Paracolletinae + Diphaglossinae .

INCLUDED GENERA: The subtribe is monogeneric.
