Abstract. The Aleiodes gasterator (Jurine) species-group is defined to include several
Palaearctic species and the following species from North America: atriconiis (Cresson),
n. comb. (= ferrugineus Enderlein, n. syn.); brachyphlebus, n. sp.; bucculentus, n. sp.;
burrus Cresson {=fulvus Cresson, n. syn., nigricoxis Viereck, n. syn., cockereUi Viereck,
n. syn.,fusicaudus, n. nud., waldeni, n. syn.); cahnatus (Ashmead) n. comb. (= pubes-
cens Ashmead, n. syn., nasonii Ashmead, n. nud.); medicinebowensis, n. sp.; smithi, n.
sp.; townesorum, n. sp.; vierecki, n. sp. The unipunctator (Thunberg) species-group also
includes several Palaearctic species and the following North American species: harrimani
(Ashmead), n. comb.; pseudoterminalis n. sp.; terminalis Cresson. Both groups have
,
small ocelli and have the marginal cell of the hind wing gradually widening to the wing
apex. Species in the gasterator group are usually unicolored yellow or orange and have
the malar space longer than the basal width of the mandible; species in the unipunctator
group are bicolored black and red and have the malar space about equal to the basal width
of the mandible.
