Etymology.

Latin, adjective and noun in apposition, for hairless, smooth, bald, glabra, and the aedeagal shaft which is devoid of any spines or processes. Gender Masculine.

Discussion.

Flavorubivolatus glabriverpus has the crown and pronotum yellowish, and the tegmina yellowish-red with this color pattern similar in males and females. Flavorubivolatus tensiverpus and F. curtiverpus are more reddish in color. Variation was found in male genitalia in apex of aedeagus, with the apex of the gonopore parallel or convergent (Fig. 15A, B View Figure 15 ). Measurement of subgenital plate variable, especially width due to imperfect horizontal orientation. The style was shorter than in other species of this genus. Connective with arms and stem of similar proportions. Dissections included 21 males and 13 females, thus 57% of males and 24% of females. No recently dissected males were parasitized, but one female abdomen contained a stylops and one female with a dryinid pupal case lateroventrally between the head and pronotum. Plant distribution records of some associated plants in Fig. 18E, F View Figure 18 ( Seriphium saxatilis , Myrovernix intricata respectively). The color pattern of Renosteria spadix corresponded to that of F. glabriverpus .
