description: <i>Neoperla agumbe</i> sp. n. (Figs. 1-3) <b>Material examined.</b> Holotype &amp;male;, <b>INDIA: Karnataka</b>, Agumbe Ghats, 13° 29.386’N, 75° 04.537’E, 9 October 2004, G. Svenson, light trap (USNM). <b>Adult habitus.</b> General color yellow-brown. Head mostly yellow but with small brown spot between ocelli; lappets and antennae pale brown. Pronotal pattern obscured by specimen condition, but disc yellow-brown with slightly darker rugosities (Fig. 1). Femora pale yellow brown, tibiae similar, but with a small, dark proximal area. Wings pale amber, veins brown except pale C, Sc and apical 2/3 of R vein. <b>Male.</b> Forewing length 7.5 mm. Hemitergal processes of tergum 10 wide basally and relatively short (Fig. 2). Process of tergum 7 triangular in outline, but with rounded apex bearing 3-4 large, spine-like sensilla basiconica. Tergum 8 with a low mound-like mesal sclerite bearing a cluster of ca. 14 small sensilla basiconica; membranous areas adjacent to mesal sclerite with a few scattered sensilla basiconica. Tergum 9 bearing a median and two small adjacent sublateral sensilla basiconica patches set on small sclerites. Aedeagal tube sclerotized and armed with three small patches of spines on each side (Fig. 3); dorsomedian patches consist of angled rows of ca. 3 spines, lateromedian patches, located ventrad to dorsomedian patches, consist of a single larger forked spine and several small spines, and lateroapical patches include ca. 7, somewhat scattered spines (Fig. 3). Aedeagal sac membranous, not fully everted in Fig. 3, but similar to tube in length and armed along dorsolateral surface for most of length with ca. 6 rows of spines; number of rows reduced distally and a ventral row of smaller spines begins near midlength (near apex of partially everted sac in Fig. 3). <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name, based on the type locality in the Agumbe Ghats, is used as a noun in apposition. <b>Diagnosis.</b> The new species is a member of the <i>N. clymene</i> group. The aedeagus of this species is similar to that of <i>N. monacha</i> Stark &amp; Sivec, 2008b in having multiple small patches of spines near midlength of the tube. However, the placement and number of spines varies between the species [compare Fig. 14 in Stark &amp; Sivec (2008b) with Fig. 3], and the sac armature, adult habitus, hemitergal processes and detail of tergum 9 are also quite different. The head and pronotum of <i>N. monacha</i> is mostly dark brown, the hemitergal processes are slender and much longer than in the new species, and tergum 9 lacks sensilla basiconica patches [see Figs. 12-14 in Stark &amp; Sivec (2008b)]. The aedeagal sac armature of <i>N. agumbe</i> is reminiscent of that of <i>N. triangulata</i> Kawai, 1975 from Sri Lanka, but that species has a pair of small spiny membranous bulbs located near the tube apex (Zwick 1980).
