description: <i>Neoperla salakot</i> sp. n. (Figs. 24-30) <b>Material examined.</b> Holotype &amp;male;, 1&amp;male; paratypes, <b>PHILIPPINE ISLANDS</b>, Palawan, Salakot Falls Road, 300 m, 19 March 1996, (Holotype PZ), 1&amp;male; paratype (PMSL) Additional paratypes: Palawan, type locality but 23-24 March 1996, 2&amp;male;, 1&amp;female; (PZ), 1&amp;female; (PMSL). Palawan, Salakot Falls Road to Napsan, 9° 42’ 9.6” N, 118° 31’ 18” E, 7 March 1998, 1&amp;male;, 1&amp;female; (PZ). Palawan, Mt. Salakot Heli-Pad, 720 m, 18 March 1996, 2&amp;male; (PZ). Palawan, San Rafael, Ulanguan, end of February 1996, 2&amp;male; (PZ). Palawan, Irawan, 22 April 1996, 1&amp;female; (PZ). Specimens deposited in the PZ collection, or the PMSL as indicated. <b>Adult habitus.</b> General color brown with areas of pale pigment. Head mostly brown with pale M-line (Fig. 27). Ocelli about 2 diameters apart. First two antennal segments pale brown, rest dark brown; palpi brown. Pronotum brown with scattered pale areas on disc. Femora banded, dark brown in distal half; tibia brown. Wings brown, veins slightly darker. <b>Male.</b> Forewing length 10 mm. Tergum 7 with a rounded, subtriangular, posteromedian lobe, and a median sclerotized area which extends onto lobe (Fig. 24); apex of lobe armed along ventroapical margin with thick sensilla basiconica. Tergum 8 with a small median sensilla patch covering a narrow sclerotized band. Tergum 9 with a pair of low median humps sparsely covered with sensilla. Hemiterga broad at midlength; hemitergal lobes slender, curved slightly laterad and somewhat expanded near apex. Penis tube slender, dorsal sclerite well developed; sac bearing an unarmed, dorsobasal, finger-like lobe, and a more distal, unarmed ventral lobe (Fig. 25). Large spines occur in a dorsolateral band distal to ventral lobe, and a smaller patch of large spines occurs distal to the first. Sac apex very slender and armed along much of length to tip. <b>Female.</b> Forewing length 13-15 mm. Subgenital plate poorly developed, not projecting beyond posterior margin of sternum 8 (Fig. 26). Vagina and spermatheca membranous (Fig. 28). <b>Egg.</b> Outline oval, collar absent. Length ca. 290 μm, width ca. 245 μm. Chorionic surface irregularly vermiculate throughout (Figs. 29-30). Micropyles with large sessile orifices located near anterior end of egg. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name, used as a noun in apposition, is based on the type locality. <b>Diagnosis.</b> The penis of this species is generally similar in outline to that of <i>N. atropennis</i> Banks, 1924. However, in that species a prominent, ventroapical, spiny lobe occurs on the penis sac margin (Sivec 1984), whereas in <i>N. salakot</i>, the penial sac lobes lack spines.
