Wing length, 1.86; width, 0.70. Head (Fig. 141A). Light brownish-yellow, lighter laterally on occiput. Scape and pedicel ochre-yellowish, flagellomeres light brown. Face and clypeus light brownish-yellow, palpomeres light brown, labella whitish-yellow. Occiput with three longer setae dorsally to eye anteriorly to lateral ocellus, three dorsally to ocellus, eight posteriorly to ocellus. Scape about 1.4× pedicel length; length of flagellomere 4 1.9× width. Palpomere 4 1.2× palpomere 3 length, palpomere 5 2.3× palpomere 4 length. Thorax. Scutum ochre-yellow with a transverse dark brown mark medially at posterior end; scutellum ochre-yellow with a brown transverse mark medially at anterior end. Antepronotum and proepisternum yellowish-brown, anepisternum, katepisternum, mesepimeron, and laterotergite light brown, metepisternum and mediotergite light brown. Scutum with 5+2 supra-alars and three pairs of prescutellar bristles, two pairs of scutellar bristles and one outer pair of long setae. Proepisternum with three bristles, anepisternum with five bristles along posterior margin. Mesepimeron with two small bristles and eight small setae, laterotergite with one bristle and ten small setae. Metepisternum with 12 fine setae and setulae. Haltere ochre-yellowish. Pleural membrane ochre-yellow. Legs. Fore coxa whitish with an orangish tinge, mid and hind coxae whitish, mid and hind coxae with a brownish band at proximal end, mid coxa brownish at anterior face distally, hind coxa with a brown mark at distal third on posterior face; Fore femur light yellowish-brown, mid and hind femora light brown; fore tibia and tarsus light yellowish-brown, hind tibia light brown, tarsus light yellowish-brown [mid tibiae and tarsi missing]. Fore tibia with two lateral bristles medially; hind tibia with 2–3 irregular rows of 5 small bristles dorsally, 2–3 bristles on inner face medio-distally. Fore leg tarsomere 1 about as long as tibia, 1.4× tarsomere 2 length. Hind tibial inner spur 5.3× tibia width at apex. Wing (Fig. 141B). Membrane fumose light brown, darker along anterior margin. Sc barely produced. C produced beyond tip of R 5 for about a fourth of distance to M 1. R 1 reaching C on distal fourth of wing; R 5 reaching C close to level of tip of M 2. First sector of Rs almost transverse, 0.60× r-m length; r-m almost longitudinal. M 1+2 about 1.0× r-m length; bM 4.6× r-m length; first sector of CuA short, 0.46× length of second sector of CuA. Cubital pseudovein absent, CuP not reaching level of origin of M 4. Anal fold only gently curved, almost reaching wing margin. Posterior veins M 1 and M 2 almost entirely with dorsal macrotrichia, M 4 with macrotrichia on distal 3/4, CuA with macrotrichia on distal fifth of wing; macrotrichia on anal lobe membrane. Abdomen. Abdominal tergites 1–6 light yellowish-brown on anterior half, light brown on posterior half, tergite 7 ochre-yellowish; sternites 1–7 light ochre-yellowish. Sternite 2 with a pair of strong brown bristles. Terminalia (Fig. 141C). Ochre-yellowish. Gonocoxites fused medially, no suture present, bare ventrally, a large medioventral projection of syngonocoxite, wide at base, with two pairs of setulae subapically, extending to about 3/4 of gonostylus length, a pair of long laterodistal extensions dorsally to insertion of gonostylus and extending much beyond tip of gonostylus, with fine setae on dorsal face on basal half and with five fine setae on inner margin on distal half, a setula at tip. Gonostylus composed of two lobes connected at base, inner lobe smaller, with a pair of longer setae at base of lobe on dorsal face and fine setae on ventral face at distal half; outer lobe larger, extending to level of tip of aedeagal distal projections, also compressed, more densely setose, with setae on both faces, more distal setae on curved inner face, larger setae along posterior end of outer face. Aedeagal-parameral complex with a pair of sclerites connected together more ventrally and projected posteriorly as a strongly sclerotized bottle-opener extending slightly beyond tip of gonostylus, and a medial short distal triangular projection more dorsally at tip, with two pairs of subapical small setae close to each other and a pair of strong spines close to tip. Gonocoxal bridge evident, incomplete medially, a pair of oblique apodemes directed anteriorly. Tergite 9 present as a pair of long laterodistal digitiform extensions, about as long as gonocoxite lateral extensions, setose at tip. Cerci not visible.</p><p>Female. Unknown.</p><p>Material examined</p><p>Holotype: male, ZRCBDP 0066740, Bukit Timah, primary forest (BT05), 30.aug.16, MIP leg. (slide-mounted).</p><p>Etymology</p><p>The species epithet honors Madame YU PEI GAO, inaugural principal of the Singapore Nanyang Girls’ School—the first Chinese educational institution for girls in Singapore. YU was an independent-minded principal who challenged obsolete traditions, such as allowing only female teachers for a girl’s school, and hired teachers based on their capabilities instead of their gender.</p><p><b>Remarks</b></p><p><i>Epicypta yupeigaoae</i> <b>sp. n.</b> is obviously close to <i>E. nus</i> <b>sp. n.</b>, as can be inferred from the uniquely derived can-opener shape of the parameres. The haplotype network leaves no question that they are separate species.</p>
