Adults with wingspan 17.5-21.0 mm in male (Fig. 4 View Figures 2–5 ), 32.5 mm in female (Fig. 5 View Figures 2–5 ). Pelecystola strigosa is characterized by the bipectinate antenna (Figs 4a, b View Figures 2–5 , 7a View Figures 6, 7 ); the forewing (Fig. 9 View Figures 8, 9 ) with R2 and R3 stalked less than half of their length, R4 and R5 stalked in basal 3/5, patterned (Figs 4 View Figures 2–5 , 5 View Figures 2–5 ) with a subtriangular basal patch in basal 1/5, with its posterior margin reaching to fold, a trapezoidal blotch at middle, and a small irregular patch near apex; the wide-deeply bilobed uncus with an ovate pouch at base of each lobe, the tegumen with a prominent triangular protrusion, the deeply divided valva with an elongate, slender stalk that enlarges apically and bearing a pectinifer consisting of minute spines in the male genitalia (Fig. 11 View Figures 10, 11 ); and the eighth sternite is strongly folded and forming a tapered plate ventral to the ostium, the elongate and slender ductus bursae, and the paired signa with each arm slender and plume-like in the female genitalia (Fig. 13 View Figures 12, 13 ).

Pelecystola strigosa was originally described in Euplocamus and later assigned to Pelecystola ( Robinson et al. 1994; Robinson and Tuck 1996; Sakai 2013), with which it shares the peculiar pedunculate pectinifer arising on a long stalk from the costal base of the valva. The species superficially resembles Pelecystola decorata except for having bipectinate antennae in both sexes. Forewing venation in P. strigosa is quite different from its congeners. R2 and R3 stalked, R4 and R5 long stalked in P. strigosa , whereas all branches of R are separate in other Pelecystola species. Additionally, the maxillary palpus (Fig. 7b View Figures 6, 7 ) in P. strigosa has four palpomeres, with a ratio of 2:1:1:1. In its allies, such as P. nearctica , there are five palpomeres.

DNA barcode.

Five DNA barcodes from four males and one female were generated and deposited in GenBank and BOLD systems: MW396739/PELE006-20, MW396740/PELE007-20, MW396741/PELE008-20, MW396742/PELE009-20, MT749676/PELE002-20. For more details see the Suppl. material 1: Table S1.
