W. Brandt // Collector // BISHOP” “ HOLOTYPE // <i>Eosphaerophoria</i> // <i>luteofasciata</i> // det. X. Mengual 20 <i>09</i> ” [red, second and third lines handwritten] USNM ENT00036555, [1♁, BPBM]. <b>Length</b> (1): body, 6.3 mm; wing, 4.7 mm. <b>Distribution:</b> Papua New Guinea. <b>Etymology.</b> The specific epithet is derived from the Latin <i>luteus</i> meaning yellow (Brown 1956: 872), and the Latin <i>fasciatus</i> meaning envelope with bands, swathe (Brown 1956: 138), and it refers to the yellow fascia (band) on the 2nd abdominal tergum. Species epithet to be treated as adjective. <b>Differential diagnosis.</b> Species with a characteristic yellow fascia on 2nd abdominal tergum, also present in <i>E. hermosa</i> and <i>E. adornata</i>, but differs from them in the absence of a tooth on the posterior margin of the scutellum. <i>E. luteofasciata</i> has posteriorly pointed scutellum, but without tooth or blunt protuberance. Male genitalia with bifurcated surstylus, divided in two similar lobes in lateral view (Figs 47a, 47d), very similar to the male genitalia of <i>E</i>. <i>bifida</i>, whose surstylus has two lobes of different sizes (Figs 44a, 44c). <b>Remarks.</b> Vockeroth (1969: 135) mentioned this species as undescribed.
