Rivula puerensis sp. nov.(Chinese name: Ḃ洱涓nj&dcaron;)urn:lsid:zoobank.org:act: 54631719-F5C0-430A-B231-2536CBD5FF96Figures 4, 5, 14Type material. Holotype. male, China, Prov. Yunnan, Puer City, Simao, 15–19 May. 2009, leg. HL. Han, MJ. Qi, genit. prep. JYY-75-1, coll. NEFU. Paratypes. 2 males, China, Prov. Yunnan, Puer City, Jiangcheng, 1–2 Aug. 2018 leg. HL. Han, MR. Li, genit. prep. JYY-73-1, JYY-74-1, coll. NEFU.Diagnosis. The new species is similar to R. calcaripuncta in morphological characters and male genitalia (Figs. 6, 15), but it differs in the following characters (characters for R. calcaripuncta are in parentheses):Adult of R. puerensis sp. nov. (Figs. 4, 5), forewing with few pale spots of various sizes, which is surrounded by black (more pale spots and pale spots even in size in calcaripuncta); ground color dark brownish black at costal margin area (uniformly colored in calcaripuncta); orbicular spot with large white dot (small white dot in calcaripuncta); the reniform spot formed by 2 irregular and small white spots, which is surrounded by black (without black in calcaripuncta).In the male genitalia of R. puerensis sp. nov. (Fig. 14), valva as long as tegumen (3/5 times longer than valva in calcaripuncta); cucullus rounded and flat (narrow and oval-shaped in calcaripuncta); saccus broad and strongly sclerotized and tongue-shaped (short and narrow in calcaripuncta). Aedeagus tube-shaped and of equal thickness, strongly sclerotized (slightly sclerotized in calcaripuncta and gradually becoming thicker from cecum to carina); carinal plate sclerotized, with spine bar (absent in calcaripuncta).Description. Adult (Figs. 4, 5). Wingspan 11–12 mm. Head yellowish brown; labial palpi brown and upcurved, extending forward but not beyond the frontal tuft; antennae brown and filiform and lighter at the base; Thorax dark brown red; patagium and tegula lighter.Abdomen dark brown, and scales scattered throughout, particularly posteriorly. Forewing brownish black to brown, costal margin much darker than ground color; the basal line only with a white dot at costal margin; antemedial line weakly excurved, before vein Cu, after Cu incurved to 2A, then excurved to inner margin, formed by 6 white dots, surrounded by black; median line only with a small white dot at costal margin; postmedial lines roughly similar to antemedial line; subterminal line dark brown to blackish brown, very thin, with white and small spots, indistinct, surrounded entirely by black; fringe long, grayish brown; orbicular spot large with white dot; reniform spot formed by 2 small and white spots, surrounded entirely by black-brown, antemedial and basal line region darker than ground color. Hindwing blackish brown with diffuse smoke gray; discal spot indistinct; fringe more chocolate-brown, but with grayish brown on inner margin.Male genitalia (Fig. 14). Uncus sclerotized, sickle-shaped, basal part broad, approximately 4/5 as long as tegumen. Tegumen broad and slightly sclerotized, inverted funnel-shaped. Vinculum slender and strongly sclerotized. Juxta narrow, slightly sclerotized, and large toast-shaped. Valva more membranous, hammer-shaped, flat on apex, and thinly covered with small trichopore; costa thinner than sacculus, nearly 1/2 width of valva base, and with a large and arc-shape concavity at basal part; cucullus membranous and rounded, flat on apex; saccus bulky and tongue-shaped.Aedeagus of equal thickness, tube-shaped, strongly sclerotized; cecum 1/4 as long as aedeagus, carina sclerotized, serrate-shaped. Vesica membranous, with 1 subbasal diverticulum, which covered shorter conical-shaped cornute plate; and 5 median diverticula, bearing numerous mastoid-shaped cornuti on the 4th and 5th median diverticulum.Female genitalia. Unknown.Bionomics. This species was collected between May and early August using a light trap near a coniferous forest. The vegetation around the holotype collection site includes Pinus yunnanensis Franch. (Pinaceae), along with grasslands predominantly featuring Poaceae plants (Figs. 20, 21).Distribution. China (Yunnan).Etymology. This species name is derived from the locality of the type, Puer.
