Remarks

• Systematics: Dactylopius gracilipilus is most similar in appearance to D. tomentosus, but they are easily distinguish by (character-states on D. tomentosus in brackets): (i) presence of abundant simple pores (absent or rare), (ii) clusters of wide-rimmed quinquelocular pores with10 or more pores abundant (large clusters of wide-rimmed pores uncommon), and (iii) truncate setae with parallel sides forming medial longitudinal rows, each seta 1.5–2 times as long as wide (setae in medial longitudinal row each less than 1.5 times as long as wide). Both D. gracilipilus and D. tomentosus infest members of the tribe Cylindropuntieae sensu Wallace and Dickie (2002) (Cactaceae). This might suggest a close affinity between these two species but D. gracilipilus appears to be restricted to Corynopuntia, whereas D. tomentosus are found on Cylindropuntia spp.,(Van Dam & May, 2012)
• Structure: Body oval, length each 1.95–2.84mm, widest point of metathorax each 1.12–2.38mm. Segmentation distinct on meso- and metathorax, and abdomen. Antennae six or seven segmented
