Description.

Male. [For measurements see Table 2 View Table 2 .] Color. Ground color yellow. Head dorsally pale yellow, with three longitudinal brown stripes between eyes; stripes connected posteriorly (Fig. 1A View Figure 1 ). Venter of head light brown (Fig. 2A View Figure 2 ). Eye golden brown. Antenna yellowish-brown to brown. Labial articles I-III light brown with brown longitudinal stripe; article IV dark brown. Pronotum pale yellow, with a dark brown median stripe throughout length and laterally with a pair of dark brown longitudinal stripes reaching slightly beyond middle of length. Mesonotum pale yellow, covered with silvery pilosity, with brown spots on anterior margin, a dark brown median stripe almost reaching posterior margin, and a pair of dark brown longitudinal stripes laterally; lateral stripes posteriorly narrowed and connected to mesopleural stripes (Fig. 2B View Figure 2 ). Metanotum velvety, dark brown with central subtriangular spot of dense silvery pubescence and two lateral spots of silvery pubescence. Mesopleura covered with silvery pubescence, with a longitudinal dark brown stripe on its ventralmost portion; stripe posteriorly connected to mesonotal stripe. Meso- and metacetabula with pruinose patches. Prosternum pale yellow; mesosternum pale yellow with two longitudinal brown spots (Fig. 2A View Figure 2 ); metasternum with posterior subtriangular dark brown spot (Fig. 2A View Figure 2 ). Abdominal mediotergite I dark brown, with silvery pubescence on posterolateral corners; mediotergite II dark brown, with central yellow spot posteriorly and silvery pubescence on posterolateral corners; mediotergites III-VI dark brown, covered with pruinose layer, with central yellow spots varying in size; mediotergites VII-VIII pale yellow, covered with abundant pubescence of same color; mediotergite VII dark brown on anterior margin. Abdominal laterotergites yellow, with patches of light setae. Abdomen laterally dark brown. Foreleg: coxa pale yellow; trochanter pale yellow, with brown lateral fringe; femur dorsally brown, ventrally pale yellow, mesal margin larerally yellow, with longitudinal white line; tibia brown; tarsus dark brown. Mid leg: coxa pale yellow; trochanter brown; femur dorsally brown, ventrally pale yellow; tibia with basal half brown and apical half dark brown; tarsus dark brown. Hind leg: coxa pale yellow; trochanter pale yellow; femur dorsally brown, ventrally pale yellow with dark brown apex; tibia and tarsus dark brown. Structure. Head with frons rounded. Antennomere I curved laterally; antennomere II shortest; antennomere IV longest (Fig. 1A, B View Figure 1 ). Fore leg: femur widened in basal half, ventrally flattened (Fig. 3A View Figure 3 ), with ventrolateral row of 4-7 small bristles; apex of tibia with long black bristles laterally and grooming structures (Fig. 4C View Figure 4 ); tarsomere I 1/4 of tarsomere II length; tarsomere II strongly curved in lateral view, flattened laterally, and apically bifid, with a shorter and a longer portion, with cuticular subconical pegs (Fig. 4B View Figure 4 ); claws long, strongly curved back (Figs 3B, C, E View Figure 3 , 4A View Figure 4 ). Mid tarsomere I with few bristles at base. Hind femur with five dorsal trichobothria. Abdominal laterotergites elevated at approximately 45° (Fig. 1A, B, D View Figure 1 ). Abdominal segment VIII dorsally with a small central notch on posterior margin (Fig. 1A, B View Figure 1 ). Paramere with apex curved up and rows of bristles close to apex (Fig. 5B, C View Figure 5 ); proctiger oval, covered with setae (Fig. 5A View Figure 5 ); sclerites as in Fig. 5 D-E View Figure 5 .

Female. [For measurements see Table 3 View Table 3 .] Similar in color and structure to male, but larger and more robust (Fig. 6A-C View Figure 6 ). Central spot on metanotum quadrate (Fig. 6A View Figure 6 ). Spot on metasternum inverted “T” -shaped (Fig. 6B View Figure 6 ). Abdominal mediotergites dark brown, with central yellow spots; mediotergites II-IX with pruinose patches laterally (Fig. 6C View Figure 6 ); laterotergites without patches of light setae (Fig. 6A View Figure 6 ). Fore leg: femur slightly curved at the base (Fig. 6D View Figure 6 ), with 3-7 bristles; tibia with grooming structures (Fig. 4D View Figure 4 ); tarsomere II cylindrical, flattened laterally (Fig. 6E View Figure 6 ). Abdominal laterotergites elevated by almost 90° (Fig. 6A View Figure 6 ).
