Head</i> (Figs. 42–43) short, transverse in dorsal view, 1.65–1.7 as wide as long, almost vertically declivent before antenniferous tubercles, widely rounded posteriad to eyes; eyes relatively small, semiglobular, protruding, width of head across eyes about 1.75 times as wide as interocular distance; antenniferous tubercles situated close to eyes, opening ventrally; frons with a median tubercle anteriorly bearing 1+1 serrate setae apically; postocular part elevated, with 5+5 serrate setae arranged in U-shaped line and a single central serrate hair; bucculae with 1+1 serrate setae at posterior angle; gula produced into 1+1 tubercles posteriorly each bearing a serrate hair apically. <i>Labium</i> (Fig. 43) thick, basal segment (segment II) cylindrical, reaching apex of prosternum, about twice as long as combined lengths of segments III+IV. <i>Antenna.</i> Segment I short and stout, narrowly pedunculate at extreme base; segment II curved, about 1.1 times as long as humeral width of pronotum, about 2.5 times as long as fused segments III+IV. <i>Pronotum</i> (Figs. 42–43) 1.9–2.0 times as wide as median length, anterior and posterior lobes indistinctly separated; anterior lobe much shorter than posterior lobe, adpressed tomentose pubescence forming 1+1 rings in dorsal view; posterior lobe about 1.6 times as wide as anterior lobe, with a median longitudinal furrow, disc with (4–6)+(4–6) serrate setae arranged in U-shaped line, lateral margin with 3 serrate setae anteriad of humeral angle; posterior margin straight anteriad of scutellum, narrowly explanate and bearing 6 serrate setae laterad to scutellum. <i>Scutellum</i> (Fig. 42) subtriangular, with 1+1 serrate setae at basal angle and 5+5 serrate setae along lateral margin. <i>Fore wing</i> (Fig. 65) wide, surpassing abdomen by nearly its apical half; corium about 0.4 times as long as total length of fore wing; posterior cell of corium very narrow, approximately as wide as the diameter of the two veins delimiting it; Cu+AA 1+2 and M approaching margin of membrane; apical half of M ramifying, forming closed cells and short free branches. <i>Legs</i> stout; fore and mid legs relatively short, covered with relatively narrow serrate setae originating from relatively small tubercles; hind femur thick, curved at base; hind tibia long, gradually narrowing towards apex, apical part strongly curved; hind femur and tibia with thick and long serrate setae originating from large tubercles, erect in dorsal surface, more gracile and more declivous in ventral surface of tibia; base of hind tibia with a brush-like tuft of serrate, whitish setae. <i>Pregenital abdomen</i> (Figs. 44–45) rounded in dorsal view; tergite VII broadly triangular; segment VIII of male (Fig. 47: VIII) membranous dorsally. <i>Male genitalia. Genital capsule</i> (Figs. 46–49) elongate, dorsally membranous, anterior and posterior apertures not separated by distinct dorsal sclerotized bridge-like portion therefore seemingly confluent; ventral rim forming a thick transverse ridge posteriorly, infolding of ventral rim with a flattened, broadly trilobed median projection (Fig. 48: mp). <i>Parameres</i> (Figs. 50–51) symmetrical, strongly curved, hook-like, their extreme apices slightly broadened (most of the hair sensilla were broken off in the examined specimen!). <i>Phallus</i> (Figs. 52–53): articulatory apparatus small, restricted to the extreme base of the phallus; basal plates short, thick; support bridge complex with 2+2 capitate processes of lateral position, continued in 1+1 greatly elongate, narrow support bridge prolongations (Fig. 52: sbp) but fused at most of their length, apically strongly bulbose; phallosoma with a large, membranous basal aula (Fig. 52: ba) provided with a pedicel (Fig. 52: ped); phallotheca relatively short, with a dorsal sclerotized plate (Fig. 52: dsp); phallotheca mouth opening between 1+1 large, thick ventroapical membranous lobes (Figs. 52: val); endosoma tubular, membranous, impossible to inflate because of rigid sclerotized elements in its wall, with processes as follows: 1+1 short and thick basal sclerites (Figs. 52–53: bsc); 1+1 struts subdivided into two portions, both articulated with the apex of support bridge prolongations: ventrobasal portions (Figs. 52–53: strvb) thick, extending to about middle of phallotheca, dorsoapical portions (Figs. 52–53: strda) elongate, whiplike, narrowing towards apex, far protruding from phallotheca; 1+1 elongate, folded lateral sclerites (Figs. 52–53: lsc). <b>Measurements</b> (holotype &amp;male; / paratype &amp;male;) (in mm). Body length to apex of fore wing 3.2 / 3.1, to apex of abdomen 1.9 / 1.9. Length of head 0.37 / 0.35, width across eyes 0.62 / 0.60, interocular distance 0.36 / 0.34, interocellar distance 0.22 / 0.22; lengths of antennal segments I, II, and III+IV as 0.19 / 0.19, 1.07 / 1.05, and 0.42 / 0.42; lenghts of labial segments II, III, and IV (visible segments I, II and III) as 0.25 / 0.27, 0.08 / 0.08, and 0.09 / 0.10; length of pronotum along meson 0.48 / 0.48, humeral width 0.95: 0.93; length of scutellum 0.18: 0.15, basal width 0.37 / 0.37; length of fore wing 2.33 / 2.32, greatest width 0.98 / 1.10; lengths of femur, tibia, and tarsus of fore leg as 0.51 / 0.46, 0.66 / 0.59, and 0.24 / 0.20; of mid leg as 0.59 / 0.52, 0.88 / 0.80, and 0.22; of hind leg as 0.73 / 0.71, 1.80 / 1.70, and 0.29 / 0.25, respectively. <b>Etymology.</b> The specific epithet is a toponymical adjective derived from Taiwan (terra typica). <b>Habitat notes.</b> A single male (the holotype) was obtained in the Fushan Botanical Garden by a canopy net through sweeping tufts of ferns growing on a tree about 4 meters above the ground. The habitat was a regularly cut meadow scattered with trees, surrounding a main road in the Botanical Garden, close to a forest edge. The paratype was captured by Malaise trap which infers the ability of the species to fly. <b>Distribution.</b> Taiwan. <b>Comparative notes.</b> <i>Locoptiris taiwanensis</i> sp. nov. is closely related to <i>L. pendleburyi</i> (Miller, 1940) described from Kuala Lumpur, the holotype of which has been examined by the first author. The two species are very similar externally, but <i>L. pendleburyi</i> is slightly smaller, its general colouration is darker, and the central spot on the fore wing is smaller. The unique holotype has not been dissected. Two additional specimens apparently representing <i>L. pendleburyi</i> and tentatively identified as such from Borneo have been examined, one of them has been dissected; its male genitalia are much different from those of <i>L. taiwanensis</i> sp. nov. Data of the dissected specimen: Malaysia, Sabah, Mt. Kinabalu, Pouring Hot Springs (43 km E of Park Headquarters), ‘Langanan Trail’, trail to Kipungit Falls and Bat Caves, 530–650 m, 21.iii.1983, leg. C. Lienhard (Pal-83/41, MHNG). Species of <i>Locoptiris</i> can be distinguished by the following key.
