description: <i>Cryptoperla fraterna</i> (Banks) (Figs. 8-10, 13-14) <i>Nogiperla fraterna</i> Banks, 1938:223. Lectotype &amp;male;, Pahang, Malaysia (Museum of Comparative Zoology), designation Stark, 1989:514 <i>Neopeltoperla fraterna</i>: Hitchcock, 1962:83 <i>Cryptoperla fraterna</i>: Uchida &amp; Isobe, 1988:20 <i>Cryptoperla fraterna</i>: Stark, 1989:514 <b>Material examined.</b> Malaysia: Hulu Perak, Belum Expedition Base Camp, 1-3 April 1994, I. Sivec, 2 &amp;male;, 1 &amp;female;, 5 larvae, 1 exuvium (PMSL). Same site, 8-10 April 1994, I. Sivec, 2 &amp;female;, 9 larvae (PMSL). <b>Remarks.</b> Stark (1989) figured variations in the male basal cercal segment for various populations of this species but the female, egg and larva have not previously been described. <b>Female.</b> Forewing length 10 mm. Subgenital plate parabolic, covering ca. half of sternum 9; margin of plate with a narrow, transparent, hairless zone <b>13</b> <b>14</b> (Fig.13). Sternum 9 produced mesally, overlapping base of sternum 10; base of sternum 9 with microtrichial band extending under subgenital plate; lateral bars present. <b>Egg.</b> Bulb shaped with low, wide collar surrounded by smooth rim. Chorion punctate with each pit surrounded by hexagonal FCIs (Figs. 8-10); FCIs larger at anterior pole opposite collar; ca. 16 longitudinal and ca. 16 horizontal rows of pits visible in lateral aspect. Micropyles subequatorial nearest anterior pole. <b>Larva.</b> Pre-emergent body length 6-7.5 mm. Dorsal body color rather uniformly reddish brown, sometimes paler on basal abdominal terga. Prothorax and thoracic sterna without gills, mesothorax and metathorax each with a supracoxal gill projecting under the wingpad; paraprocts each with a slender, delicate dorsal gill filament, median gill reduced and obscure on membranous ventral margin of tergum 10. Lacinia tridentate, mesal tooth slightly larger that laterals; galea brush expanded, much wider than apex of lacinia. Thoracic sterna without posterior or subapical setal fringes; fringes confined to anterior margin of prosternum and lateral margins of mesosternum and metasternum around coxae; posterior margin of metasternum concave (Fig. 14). Abdominal sterna 1-4 without posterior setal fringe; fringe on sternum 5 interrupted mesally but complete on sterna 6-9. Cerci short and without ventral blade-like setae in apical whorls.
