description: <i>Togoperla limbata</i> (Pictet) (Figs. 21&amp;hyphen;27) <i>Perla limbata</i> Pictet, 1841:219. Lectotype &amp;male; (ZMB), Japan, desig. Zwick, 1972 <i>Perla</i> (<i>Togoperla</i>) <i>kawamurae</i> Okamoto, 1912:123. Holotype &amp;female; (Hokkaido University, Sapporo, lost), Japan, syn. Sivec et al., 1988. <i>Perla</i> (<i>Togoperla</i>) <i>matsumurae</i> Okamoto, 1912. Lectotype &amp;female;, (Hokkaido University, Sapporo), Haki, Japan, design. Uchida, 1990, syn. Sivec et al., 1988. <b>Material examined.</b> Japan: Unknown locality, 4 July 1981, S. Uchida, 1 &amp;male; (PMSL). Hozuyama, Kuwada Gori, Tamba, June 1897, 3 &amp;female; (??). Honshu, Obama, May 1926, 1 &amp;male; (CSU). <b>Adult habitus.</b> General color brown. Head with dark brown pigment over ocelli and forward of M&amp;hyphen; line; occiput dusky brown. Pronotum brown but usually with pale anterolateral areas on disc (Fig. 21). Wings brown except costal area pale. Legs entirely brown, without distinctive banding. <b>Male.</b> Forewing length 19&amp;hyphen;22 mm. T 5 produced into a notched or emarginate lobe; T 6&amp;hyphen; T 9 typical; membrane of T 6&amp;hyphen; T 9 bearing patches of mixed setae and scattered sensilla basiconica. Dorsal aspect of hemiterga moderately long and attenuated from basal callus to tip; length from basal callus to hemitergal tip about 1.3&amp;hyphen;1.5 times as long as basal callus (Fig. 22); lateral aspect of hemiterga slender across basal curve and gradually narrowed to form a slender triangular structure (Fig. 23); sensilla basiconica clustered on basal callus and sparse on hemitergal tip. Membranous aedeagal sac armed with a coarse band of variably sized spines from subapical lobes to about midlength of tube (Fig. 25); largest spines occur in a band somewhat proximal to margin of spinous zone; apex of sac extends as a nose like lobe below a pair of membranous, unarmed dorsal lobes; apical lobe armed at tip with a zone of slender, long spines; tube with a pair of midlateral spiny lobes. <b>Female.</b> Forewing length 24&amp;hyphen;29 mm. Subgenital plate parabolic without apical emargination or notch. Dorsal membrane of plate with a short sclerotized mesal band reaching less than halfway to base of plate (Fig. 26). Vagina with essentially parallel sides, or sides slightly constricted at back of chamber (Fig. 27); accessory glands about half as long as vagina. <b>Egg.</b> Length 0.38&amp;hyphen;0.42 mm, width 0.31&amp;hyphen;0.34 mm. Collar expressed as a small dark brown disc. Micropyles oriented almost perpendicular to long axis of egg; micropylar row set almost halfway between equator and pole. <b>Distribution.</b> Known only from Japan. <b>Remarks.</b> Sivec et al. (1988) proposed the synonymy of <i>T. kawamurae</i> and <i>T. matsumurae</i> with <i>T. limbata</i> but omitted supporting data. Uchida (1990) supported these synonymies in his thesis, but this has remained unpublished. We accept and validate the lectotype for <i>T. matsumurae,</i> previously selected by Uchida (1990) in his thesis, which bears label data of, Haki, 8/10, <i>Perla matsumurae</i> Okam., Sesuji&amp;hyphen; kawagera, &amp; Lectotype, <i>Perla matsumurae</i> Okamoto, S. Uchida det. 1984, HU, and is in the Hokkaido University collection, Sapporo. Uchida (1990) also described a second Japanese <i>Togoperla</i> species, generally similar to <i>T. limbata,</i> but differing in details of aedeagal armature, however this description has not been published and we have seen no material. Male hemiterga of this species are generally similar to those of <i>T. fortunati, T. poilanina</i> and others, however it is easily distinguished by virtue of geography and by the pattern of armature on the aedeagus.
