description: <i>Cryptoperla meyi</i> sp. nov. (Figs. 29-30, 33-35) <b>Material examined.</b> Holotype &amp;male; from Vietnam, Sa Pa, Fan Si Pang Mts., 25-30 March 1995, W. Mey (MNB). Paratypes all from Vietnam: Mt. Fan Si Pan, 22 <b>°</b> 17’ N, 103 <b>°</b> 45’ E, 1-5 March, 1 &amp;female; (MNB). Sa Pa, Okui-ho 1100 m, 24-25 March 1995, W. Mey, 1 &amp;female; (MNB). <b>Adult habitus.</b> Biocellate. General body color yellowbrown. Head pale except for darker lappets. Pronotum with pale median band and darker midlateral band extending almost to margin; small pale rugosities scattered in dark band (Fig. 29). Wings transparent, veins pale amber except costa, subcosta and radius which are pale in apical half. Femora pale except at tip; tibiae brown but slightly darker in basal third. <b>Male.</b> Unknown. <b>Female.</b> Forewing length 16-17 mm. Subgenital plate large, parabolic, covering most of sternum 9 (Fig.30). Sternum 9 with prominent lateral bars; median field essentially hairless. Base of vagina visible through subgenital plate due to microtrichia patches. <b>Egg.</b> Outline thimble shaped with low button collar surrounded by wide smooth zone (Figs. 33-35). Body of egg covered with prominent 4-6 sided FCIs; ca. 7 longitudinal and 10 horizontal rows of FCIs in lateral aspect. FCI floors form conical pits, rims smooth and narrow (Fig. 35). Micropyles located near collar on FCI rims. <b>Larva.</b> Unknown. <b>Etymology.</b> The patronym honors W. Mey, collector of the holotype. <b>Diagnosis.</b> The subgenital plate for this species is generally similar to that of several other species, but <i>C. meyi</i> is larger than known <i>Cryptoperla</i> except <i>C. kumari</i> (Stark 1989) and two Chinese species, <i>C. obtusa</i> (Wu 1973) and <i>C. sinensis</i> (Wu &amp; Claassen 1934). Wu (1973) reports male <i>C. obtusa</i> to have a body length of 18 mm and Wu &amp; Claassen (1934) list the female body length for <i>C. sinensis</i> to be 17 mm. If these sizes are accurate, both these species should have longer wing lengths than <i>C. meyi</i>. The female for the former species is unknown, but the redescription of the latter <b>39</b> <b>40</b> species (Stark 1989) indicates its subgenital plate is shorter and more broadly rounded than that of <i>C. meyi</i>. The newspecies differs from <i>C. kumari</i> females in having a slightly less parabolic subgenital plate, more prominent lateral bars, and microtrichial bands in the vaginal base. In addition, the pale pronotal band and almost entirely pale head are distinctive for <i>C. meyi</i>. Unfortunately the eggs are not known for <i>C. obtusa, C. kumari,</i> or <i>C. sinensis.</i>
