Diagnosis. Porcellanola gaofengensis is barely distinguished from P. minna and P. chakri on external feature, except a triangular spot filled with metallic-blueish color at base of forewing and a relatively big subterminal area of forewing in P. gaofengensis . In male genitalia, P. gaofengensis has a triangular juxta with the serrated margin and aedeagus with the serrated processus, while juxta huge with the two long and slender arms on either side and aedeagus without any processus in P. c h ak r i and P. minna .

Description. Adult (Figs 1 & 2). Wingspan 14–16 mm. Head white; antennae brown except white at basal part, filiform, with a row of short hairs on one side; labial palpi short, inside gray and outside brown. Thorax grayish white. Abdomen brown and white. Forewing ground color white; a metallic-blueish spot with the black margin at base; antemedial and medial lines shape the triangular spot filled with a little metallic-blueish color before cell; postmedial line black, the front part shapes the circle with the counterpart of medial line before M3, then straight line to Cu2 and arc-shaped line to inner margin; subterminal line black and waved, more running to terminal line; terminal line faint and black; terminal area narrow, reddish brown; subterminal area relatively big, grayish black; cilia blackish brown. Hind wing ground color gray; veins highlighted. Male genitalia ( Fig 7 ): Uncus long and narrow, apically hook shaped; tegumen relatively narrow, almost as long as uncus; valva flat and broad, tongueshaped, with many hairs; costal margin sclerotized; sacculus long and rectangular, processus schistose; harpe short and finger-shaped; juxta triangular and sclerotized, with the serrated margin; saccus small and U-shaped. Aedeagus cylindrical, with a row of triangular protrusions at front; vesica without cornuti. Female genitalia ( Fig 10 ): Papillae anales conical; apophyses posteriores medium-long, well developed; apophyses anteriores very short; ostium rather broad, infundibular, strongly sclerotized; ductus bursae very short, membranous; corpus bursae large, ellipticalovoid, membranous, without stigma.
