Group Triater

This group is now expanded to include D. apostata Hering, 1937 and D. nigriscutatus White, 2006; this removes the Apostata group name from the classification. White (2006) separated the Apostata and Triater groups by the presence or absence of a pecten. The strong similarity of D. pseudapostata sp.n. to D. apostata, from which it differs in the absence of a pecten, indicates that these two groups are inseparable. Additionally, known hosts of both groups are Zehneria spp. ( Cucurbitaceae) (White 2006), and Virgilio et al. (in press) found that DNA studies muddled representatives of both groups into a single well defined clade.
