Antenna mostly yellow; basal flagellomere tannish yellow apicodorsally; arista with 5 dorsal rays. Face at narrowest point about equal to combined length of pedicel and basal flagellomere; face more densely microtomentose than frons, microtomentum with faintly shiny, mostly gray to whitish gray; parafacial and gena becoming slightly more whitish to silvery white than face; parafacial becoming wider ventrally with moderate ventral dilation; gena moderately high, height less than combined length of pedicel and basal flagellomere; gena-to-eye ratio 0.17-0.21.</paragraph>

Legs, including most of coxae, yellow; forefemur lacking a row of 9-10 short, stout setulae along apical half of anteroventral surface; forefemur with a row of 4-5, of moderately well-developed, evenly spaced, posteroventral setae on apical half, each seta less than width of femur; tibiae mostly gray, only apices yellowish; basal tarsomeres yellow, apical 1-2 becoming slightly darker, mostly tannish yellow.</paragraph>
