Aleiodes quasiburrus Fortier , NEW SPECIES

( Figures 11, 12 )

Holotype. ♂ WASHINGTON, Okanogan County, west of Omak Lake , 48 O 18’07”N; 119 O 26’41”W, June 1-10, 2020, J. Fortier. Deposited in USNM.

Male. Body color: Body bicolored, head, antennae, maxillary and labial palps entirely black except sometimes with yellow-orange on sides of face adjacent to eyes; mandibles with orange; mesosoma entirely black; coxae and trochanters of all legs black; first 3 metasomal tergites variable, usually with base of first tergite and apex of third tergite black or infumate, tergites otherwise yellow-orange, sometimes with first 3 tergites entirely yellow-orange, sometimes with first tergite mostly black or infumate; tergites 4-6 black; wings hyaline, fore wing veins light brown basally becoming dark brown or black apically, base of 1RS usually yellow-orange, hind wing veins light brown, sometimes darker apically. Body length: 5.9 – 6.3 mm; Forewing length: 5.0 mm. Head: ocellar diameter smaller than ocell-ocular distance; 52 flagellomeres, except for 2 basal flagellomeres all flagellomeres with length about equal to width; malar space about 1.3 as wide as base of mandible; face rugose-areolate; frons and vertex rugose. Legs: hind coxa shiny with transverse carinae dorsally, tarsal claws not pectinate, inner tibial spur of hind leg 1/3 length of basal tarsomere. Wings: fore wing vein r 0.6 length of 3RSa, second submarginal cell trapezoidal, 3RSa 0.7 length of 2M, vein 1cu-a distal of 1M by a distance greater than length of 1cu-a, hind wing RS parallel to R1 for basal half of length, bending slightly posteriorly, marginal cell widening in apical half, m-cu spectral or faintly infumate. Mesonotum: pronotum rugose; mesonotum punctate, mesopleuron rugose except punctate medially; propodeum rugose, median carina absent. Metanotum: first and second metasomal tergites rugocostate, costae distinct; third metasomal tergite carinate on basal ¾, sometimes entirely, median carina either very faintly distinct from other carinae or absent.

Comments. Aleiodes quasiburrus is similar in appearance to males of A. burrus Cresson and to A. harrimani (Ashmead) . It can be distinguished from A. burrus by the first metasomal tergite with distinct costae rather than entirely rugose as in A. burrus , and by the absence of a complete median carina on the propodeum in contrast to median carina complete in A. burrus . A quasiburrus can be distinguished from A. harrimani by long malar space, twice as long as mandible basal width as opposed to shorter malar space in A. harrimani , and all legs with black coxa and trochanter as opposed to only hind coxa black in A. harrimani .

Etymology. The specific name is from the Latin quasi for “similar to” and burrus , which is the specific name for an Aleiodes species to which this species is most similar.
