Lateral seta (c2) 31 (31­36), on annulus 1 (1) counting from genitalia rear margin; ventral seta I (d) 40 (broken) (66­80), 46 (44­51) apart, on annulus 15 (11­16); ventral seta II (e) 48 (48­60), 30 (27­33) apart, on annulus 34 (29­36); ventral seta III (f) 29 (27­29), 30 (26­30) apart, on annulus 54 (46­55) or 10 (10­11)th from rear. Total ventral annuli 63 (55­65), microtuberculate; total dorsal annuli 72 (72­78), with irregularly spaced minute pinlike structures (excretory ducts of glands? tiny microtubercles?).

TYPE MATERIAL ­ Female holotype, 23 female and 6 male paratypes, from Euge­

RELATION TO HOST ­ vagrant on the lower leaf surface; no visible damage.
ETYMOLOGY ­ The specific designation, nudipalpus, from the Latin, nudus, bare, refers to the absence of the antapical seta on the palp.
