Laphria royalensis (Bromley):

    face hairs on upper portion of face erect, yellow, except for two to three black hairs along upper eye margin; hairs on central portion of face erect, yellow, these grade into similar but procumbent yellow hairs laterally, which project over the gibbosity to each side; hairs on gibbosity erect, yellow from about one-fourth distance from top of oral margin to top of gibbosity in middle, and from above about one-half the depth of the gibbosity along the eye margins; hairs on lower portion of gibbosity black; area framed on each side of the oral margin by the gibbosity dorsally, and the inner margin of the eye dorsolaterally, is bare

    beard entirely yellow

    hairs underneath the proboscis yellow in male; in female, on basal portion yellow, on more distal portion (but still at base of proboscis), black

    palpal hairs hairs on first segment yellow, hairs on second segment black

    postpronotal lobes with long yellow hairs

    mesonotum in male, covered, except for notopleural areas, with long yellow hairs, which nowhere completely obscure the blue black ground color; anterior to the transverse suture about equal numbers of these hairs are either erect or recumbent; posterior to the suture they are all erect and somewhat longer; on the suture itself they are sparser, and from the effect of the cuticle showing through more strongly, give the impression of an indistinct, transverse black band; laterally this band is contiguous with black hairs on the notopleurae; posterior calli likewise with yellow hairs; as is usual these are longer than those on the anterior mesonotum; female similar, except that black hairs may occasionally be present in small numbers on the intra-alar areas and are invariably present in larger numbers on the extreme lateral margins of the posterior calli

    tuft of hairs in front of wings black

    tuft of hairs in front of haltere mostly yellow

    scutellar hairs on disk, sparse, black, medium length and slanted at about a 45 degree angle backwards; on margin long, erect, with a preponderance of yellow over black bristles

    ground color of legs from a distance the ground color appears to be black, but when viewed with a dissecting microscope, from an angle the surface appears to be blue black, and when viewed directly, that is from right angles, with artificial light, it appears to be very dark reddish brown; the surface is also highly reflective and where yellow hairs are present on the tibiae, reflects these as reddish brown

    fore- and mid-tibiae black haired

    hind tibiae black haired

    hind femora weak line of scattered yellow hairs stretching from near base to about three fourths way to apex; "knee" or apex entirely black haired

    abdominal segments in male, tergites 1-3 with short black hairs medially, grading into long black hairs on extreme lateral margins; these short hairs let the ground color show through, making the tergites appear shiny black centrally; on tergite 3, yellow hairs, which are also longer, restricted to laterodorsal, posterior patches, on tergite 4 these long yellow hairs are present everywhere, except anteriorly in the middle, where they are replaced by short black hairs, and on tergites 5-7, they cover the entire upper surface from one side to the other; female identical, except tergite 7 is entirely covered with long black hairs
