( Figs. 16-18 ) Material examined. Holotype ♂ from Vietnam , Lao Cai , ca. 12 km along road from Sapa to Lai Chau , 1950 m , 22° 20’ 58.3” N , 103° 46’ 15.7” E , ROM 992002, Malaise trap , 1-12 May 1999 , B. Hubley ( ROM ) . Paratypes : Vietnam : Lao Cai , Sapa , Okui-Ho, 1100 m , 24-25 March 1995 , W. Mey , 9♂ ( ZMB ) . Adult habitus. General color brown. Head brown without distinctive pattern; 2 nd antennal segment darker than basal segment, flagellum dark brown. Pronotum pale brown with darker rugosities on central disk. Wings brown, veins dark brown. Femora brown, becoming darker on dorsum and near apex; tibiae dark brown. Male. Forewing length 8.5 mm . Epiproct broad in dorsal aspect with parallel lateral margins; apex with shallow V-shaped notch from which a short, downturned process projects ( Fig. 16 ). Lateral aspect of epiproct bulbous ventrally ( Fig. 18 ) and ventral sclerite bearing a row of prominent median spines. Tergum 10 with a pair of low humps under epiproct and with a large arcuate membranous area near anteromedian margin. Cerci somewhat inflated basally in dorsal aspect. Mesal paraproct lobe slender, elongate and recurved over tip of abdomen; caudal aspect with an outer marginal row of tiny subapical serrae; inner lobe a short triangular sclerite; outer lobe a short club shaped structure in lateral aspect ( Fig. 17 ). Vesicle long and slender. Female. Unknown Larva. Unknown. Etymology. The patronym honors W. Mey for his generosity in providing specimens for this and other studies of Asian stoneflies. Diagnosis. The general shape of the epiproct of this species bears some similarity with that of A. cordiformis Li & Yang , particularly in lateral aspect where both are abruptly swollen near midlength, and both bear prominent spines along the swollen sclerite. However, A. meyi lacks the “…heart- shaped projection on the dorsal sclerite…” mentioned by Li & Yang (2006) .
