Redescription. Body color in life. Overall body color light-brown, with hyaline lamina (Fig. 1).
Body ornamentation. Dorsal surface covered with dense, tiny, granular sculpturing (gs) usually organized in polygonal pattern (Figs 2, 3 A–C, 3E). Granular sculpturing is of different lengths and shapes, but mostly rounded (Fig. 3E). Modified nodule-like setae (nls) scattered among granular sculpturing (Figs 2, 3 A–B, 3E); setae higher than granular sculpturing and composed of two layers of dentate crowns with a central, pointed projection (Fig. 3E); nodule-like setae distributed on all dorsal body surfaces, except on lobules (lb) (Figs 3 A–B, 3D). Lobules dorsally covered with many minute, pointed projections (Fig. 3D), ventrally bare. Ventral surface of laminae bearing many scattered pointed setae (Figs 4A, 4C). Marginal setae (ms) are slightly clubbed, with dorsal surface bearing many pointed projections, similar to those covering lobules (Figs 3D, 3F). Lobules bearing a small seta, similar to marginal setae in shape, but with about half of their length, located close to base of marginal seta (Fig. 3D). Ventral surface of the body covered with scattered, pointed setae and with minute granulations on intersegmental region, between legs and in a narrow strip around legs. Imbricated between granulation are small, rounded glands (Fig. 4B). Abdominal spiracle rounded (Fig. 4B).
Head. Antenna four-segmented, geniculate (Figs 2A, 4A); first article thin, evenly widened apically, long, length approximately equal to that of three remaining articles combined; second article rounded; third article cylindrical with proximal portion narrowed; second and third article short, with about one fourth of first article length; fourth article elongated, subequal in length to the second article, tapering apically (Fig. 4A). Articles covered with scattered, pointed setae (Fig. 4A). Labium three-segmented. Coiled stylets visible in diaphanized specimens.
Legs. Short, robust, with stout femora, greatest widths of femora 3.5–4.0 times width of tibiae; tibiae laterally compressed, narrowed basally; tarsi dimerous, first tarsomere about one-half size of second; claw large and without teeth; pulvilli slender and capitated, spatula-like, lengths nearly as long as that of claw. Foretibia with longitudinal row of erect setae. Apices of mid and hind tibiae with stout setae.
Number of laminae: 11 in males, 12 in females and 14 in last instar nymph. Laminae (lm) with lobules arranged as follows in adults: 8♂, 7♀ (head I), 3♂, 4♀ (head II), 10♂, 11♀ (prothorax), 12 (mesothorax plus metathorax), 7 (abdominal I), 8 (abdominal II), 8 (abdominal III), 8 (abdominal IV), 7 (abdominal V), 8♂, 7♀ (abdominal VI), 4 (abdominal VII), 3♀ (abdominal VIII, absent in male) (Fig. 2A). Last instar nymphs: 6 (head I), 3 (head II), 7 (prothorax), 4 (mesothorax I), 4 (mesothorax II), 4 (metathorax), 4 (abdominal I), 4 (abdominal II), 4 (abdominal III), 4 (abdominal IV), 4 (abdominal V), 4 (abdominal VI), 4 (abdominal VII) and 3 (abdominal VIII) (Fig. 2B).
Measurements. Body length: 2.6–2.7 mm; maximum width: 1.7–1.8 mm.
Male terminalia (Figs 5 A–B). Pygophore (pyg) rounded; paramere (par) elongated and thin, slightly arched, with pointed tip; phallobase (phb) longer than wide; ejaculatory reservoir (ejr) hammer-shaped; aedeagus (aed) tubular, elongated and twisted; capitate processes rounded.
Female terminalia (Fig. 5C). Spermathecal bulb (sb) elliptical, slightly dorsoventrally flattened and sclerotized; pumping region (pr) tubular, proximal and distal flanges not differentiated; spermathecal duct (sd) very long, tubular and twisted, with distal third narrowed; outgrowth of spermathecal duct (osd) well-developed, elongate and sackshaped.
