by: Hurd and Linsley

GEOGRAPHIC RANGE.—Southwestern United States (Arizona).
HOST.—Pseudopanurgus nanulus Timberlake

FEMALE.—Head black, mesoscutum of thorax largely black, otherwise thorax chiefly or entirely red¬dish brown; metasoma chiefly or least extensively red¬dish brown, usually with terga clouded or darkened with black medially; antennae, clypeus, mandibles, tegulae, and legs usually reddened, sometimes nearly dark mahogany red; calcaria pale reddish brown. Ves-titure of body chiefly white (extensively intermixed or supplanted with golden or reddish golden pubes¬cence on dorsally exposed body surfaces), mostly closely appresscd and forming patches on face, about antennal insertions and above, vertex, hind margins of head, mesonotal line, dorsal surfaces of pronotum, mesoscutum especially anteriorly, mesepisterna, scu¬tellum laterally and medially and propodeum at sides; dorsal surfaces of head, thorax, and metasoma con¬spicuously clothed with golden or reddish golden pubescence. Wings almost imperceptibly violaceous, scarcely darkened apically. Length 2.5-4 mm. Eyes bare; face above antennae closely and coarsely punc¬tate, neither bigibbosely swollen nor largely impunc-tate; antennae with first flagellar segment much shorter than combined length of succeeding two seg¬ments; anterior and lateral ocelli separated by less than twice their diameters; interocellar distance shorter than ocellorbital distance; rear angle of man¬dible situated well behind middle of eye; labrum not longitudinally carinate medially, without a thornlike tubercle near base, closely punctate on basal half or more, without impunctate or sparsely punctate shiny areas basally; ventral surface of head rather closely and finely punctate adjacent to hypostomal carinae, interspaces dull and tessellate. Mesoscutum closely and finely punctured throughout; scutellum entire or at most only weakly indented medially on posterior dorsal surface, not prominently bilobed and not con¬spicuously elevated posteriorly; metanotum not pro¬duced posterolaterally into prominent, posteriorly projected shelflike processes; mesepisternum rather coarsely and nearly rugosely punctate dorsally and with an evanescent and largely incomplete patch of white pubescence; forewing with second submarginal cell unusually small, much shorter than one-half as long as first submarginal cell when measured along posterior side; spur of middle leg more than one-half as long as corresponding basitarsus. Metasomal terga II-IV basally with two discrete spots of white pubes¬cence on either side of middle, dorsal surface of first metasomal tergum with an irregular patch of white pubescence laterally; apical margin of tergum IV usually with a small patch of white pubescence later¬ally on each side; pygidial plate truncate apically, rounded laterally; fifth metasomal sternum angularly cmarginate medially.

MALE.—Similar to female in coloration of integu¬ment and vestiture. Length 2.5-3.5 mm. Eyes, face, antennae, ocelli, rear angles of mandibles, labrum, ventral surface of head essentially as in female. Meso¬scutum, scutellum, metanotum, mesepisternum, and wings as in female; tegulae reticulately punctate throughout. Metasomal terga II-V basally with two discrete spots of white pubescence on either side of middle, dorsal surface of first metasomal tergum with a somewhat triangular spot on each side; apical mar¬gins of terga IV and V with a small band or spot of white pubescence laterally; basin of metasoma not sharply defined, punctate throughout; apical margin of sixth metasomal tergum not bisinuate in outline, without a median triangular projection; seventh meta¬somal tergum with lateral margins as seen from above, evenly rounded, not angulately produced on either side of pygidial plate; pygidial plate short, not twice as long as maximum basal width, parallel sided, nar¬rowly liguliform in outline.
