Yemmatropis nigrovittatus Cai & Bu View in CoL , sp. nov.
( Figs. 1 View FIGURE 1 E, F; 2D; 3D, H)
Diagnosis. Yemmatropis nigrovittatus sp. nov. can be distinguished from all other species in this genus by the black punctures on pronotum dorsally, the black apex of frons, the bands from antennal bases to suture of anterior lobe of head, and the area around ocelli ( Fig. 1 View FIGURE 1 E). Furthermore, Y. nigrovittatus sp. nov. is distinguished from Y. dispar by the complete woolly band behind the eye, the black apical 1/4 of clypeus ( Fig. 2 View FIGURE 2 D), and the bluntly projecting inner projection of paramere ( Fig. 3 View FIGURE 3. A – D H); from Y. erectus by the short, prostrate scutellar spine ( Fig. 1 View FIGURE 1 E), the largely pale brown clypeus with only the apical 1/4 black ( Fig. 2 View FIGURE 2 D), and the round apex of cuplike sclerite of male genital capsule ( Fig. 3D View FIGURE 3. A – D ), and the relatively slender blade of paramere ( Fig. 3 View FIGURE 3. A – D H); from Y. hsiaoi sp. nov. by the complete woolly band behind the eye ( Fig. 2 View FIGURE 2 D), the round apex of lateral projection of male genital capsule ( Fig. 3D View FIGURE 3. A – D ), and the slightly projecting inner projection of paramere ( Fig. 3 View FIGURE 3. A – D H).
Description. Male (n = 12). Length 6.69–7.50 mm, width across hemelytra 0.88–0.98 mm. General coloration pale brown, with ventral surfaces of head and thorax black. Head ( Figs. 1 View FIGURE 1 E, 2D): length 0.74–0.81 mm, width 0.57–0.59 mm; pale brown dorsally, except black on apex of frons, bands from antennal bases to suture of anterior lobe, and area around ocelli; black on ventral from midline of eye including lorum and apical 1/4 of clypeus, and dark brown on lateral of clypeus; black around base behind ocelli; bands of woolly setae extending from base of head to middle of eye around ventral margin of eye to lorum (covering most of lorum), from ocellus along suture of posterior lobe to connect lateral band, and across anterior margin of frons between antennal bases. Rostrum: length 2.28–2.53 mm, extending beyond metacoxae to abdominal segment II. Antenna: segment I, length 5.19–5.75 mm; II, 2.48–2.80 mm; III, 3.34–3.70 mm; IV, 1.00– 1.05 mm; segments I–III pale brown to dark brown, segment I with numerous fine, dark brown spots; segment IV fusiform, black, apical 1/5 pale yellow. Pronotum ( Figs. 1 View FIGURE 1 E; 2D): length 1.14–1.24 mm, maximum width 0.75–0.85 mm; deeply and uniformly punctate except for impunctate calli; pale brown except for black punctures dorsally and shiny black quadrate area above and anterior to proacetabula. Scutellar spine ( Figs. 1 View FIGURE 1 E, F): short, prostrate, length 0.18–0.21 mm. Hemelytron: dark brown, weakly tinged and streaked with darker brown. Ventral surface: abdomen pale brown except for shiny black, grooved segment II; largely glabrous except for narrow band of woolly setae along rostral groove and posterior and lateral margins of segment II; thoracic surface shiny black, with narrow bands of woolly setae bordering rostral groove and margins of pronotum. External scent efferent system ( Figs. 1 View FIGURE 1 E, F): evaporatorium limited to metapleuron, dark gray, scent channel black; erect part of spout pale yellow. Legs: pale brown; femora with numerous dark brown spots, some coalescent to form larger spots; tibiae pale brown, with scattered, indistinct dark brown spots; tarsi dark brown, claws black. Femoral lengths: profemur 3.16–3.76 mm; mesofemur 3.60–4.24 mm; metafemur 5.66–6.16 mm. Tibial lengths: protibia 3.92–4.56 mm; mesotibia 4.48–5.12 mm; metatibia 7.38–8.19 mm. Opening of male genital capsule and paramere as shown in Fig. 3D View FIGURE 3. A – D , H.
Female (n = 15). Length 7.63–8.50 mm, width across hemelytra 0.93–1.05 mm. Head: length 0.88–0.93 mm, width 0.60–0.61 mm. Rostrum: length 2.62–2.72 mm. Antenna: segment I, length 5.20–5.76 mm; II, 2.44–2.72 mm; III, 3.36–3.64 mm; IV, 0.91–0.95 mm. Pronotum: length 1.29–1.40 mm, maximum width 0.83–0.93 mm. Scutellar spine: length 0.20–0.23 mm. Femoral lengths: profemur 3.16–3.72 mm; mesofemur 3.76–4.08 mm; metafemur 5.56–6.08 mm. Tibial lengths: protibia 3.90–4.25 mm; mesotibia 4.48–4.64 mm; metatibia 8.00– 8.13 mm. Similar to male in color and pubescence.
Etymology. The specific epithet nigrovittatus (Latin adjective, meaning black striated) is used to denote the black bands from antennal bases to suture of anterior lobe on the head.
