description: <b> <i>Phanoperla lobata</i> sp. n.</b> (Figs. 16-18) <b>Material examined.</b> Holotype &amp;male; and 4&amp;male; paratypes from Dong Nai, Vietnam, Cat Tien National Park, stream N of Park Headquarters, 120 m, 23 August 1998, B. Hubley, D. Currie, ROM 982006 (holotype ROM, paratypes ROM, IEBR). Additional paratypes: Vietnam: Dong Nai, Cat Tien National Park, stream N of Park Headquarters, 120 m, 22 August 1998, B. Hubley, D. Currie, ROM 982002, 2&amp;male; (BPS). Dong Nai, Cat Tien National Park, gazebo near Park Headquarters, Dong Nai River, 31 May 1999, D. Currie, D.C. Darling, B. Hubley, ROM 993045, 1&amp;male; (ROM). Nam Cat Tien, 200 m, 17-25 June 1995, H. Malicky, 1&amp;male; (PMSL). <b>Adult habitus.</b> Biocellate. General body color in alcohol pale without dark markings on head. Pronotum pale with obscure, slightly darker rugosities; entire pronotal margins dark brown. Wings membranous, veins pale brown; Rs with two branches. Legs pale brown. <b>Male.</b> Forewing 7.0-7.5 mm. Tergum 8 with a wide, slightly produced median lobe. Tergum 9 with median and two lateral sensilla basiconica patches set on low humps. Process of hemitergal lobes curved slightly laterad, wide basally and tapered to tip (Fig. 16). Mesal clusters of long setae present on abdominal sterna 5-7. Aedeagal tube and sac without lateral lobes; dorsal sclerite rhomboid-shaped and almost as long as tube; sac short, plump, curved ventrad and armed laterally with prominent transverse double rows of lateral spines; spine rows incomplete on dorsal (Fig. 18) and ventral (Fig. 17) margins; larger more basally located row in lateral aspect consists of 6-8 large black cultriform spines; smaller more apically located row in lateral aspect consists of ca. 6 smaller, black cultriform spines; additional clusters of smaller spines occur on each side of large spine rows, and another cluster of relatively large spines occurs near apex (Figs. 17-18). <b>Female.</b> Unknown. <b>Larva.</b> Unknown. <b>Etymology.</b> The species name refers to the presence of a small lobe on the male 9 th tergum. <b>Diagnosis.</b> The absence of lateral lobes and the aedeagal armature detail of this species are similar to those features in <i>P. incompleta</i> Zwick, but that species has many more spines in the double rows and the spines are more similar in size. In addition, <i>P. incompleta</i> has no lobe on tergum 8 (Zwick 1986). The aedeagus is also similar to that of <i>P. namcattien,</i> a new species proposed by Cao &amp; Bae (2009) from Nam Cat Tien, but that species is shown to have longer, more slender spines with a more extensive subapical grouping and it apparently also lacks a lobe on tergum 8. Specimens of <i>P. namcattien</i> were unavailable to us.
