The text in Wood’s couplets has been extensively re-arranged and paraphrased, such that it is not possible to identify his original text.
7 (6) Declivity clearly sulcate with interstriae 3 elevated; submarginal crenulations on elytral bases entirely absent ( Fig. 1 A,E View FIGURE 1 , Fig. 3 A,E View FIGURE 3 ); declivital sulcus poorly developed (Fig, 1D, H, Fig. 3 D,H View FIGURE 3 )..............................................7’
- Declivity flattened or rounded, interstriae 3 not notably elevated; one pair of small submarginal crenulations present at base of interstriae 2 ( Fig. 4 A,E View FIGURE 4 ); declivital interstriae 2 more strongly impressed, 3 weakly but distinctly elevated at least apically ( Fig. 4 D,H View FIGURE 4 ); small patches of light scales irregularly scattered on pronotum and elytra; erect interstrial scales less than three times as long as wide; Hidalgo; Hosts composite shrubs in xeric habitats; 1.6–2.0 mm........................ sulcatus (Wood)
