Micranops sagittifer, sp. nov. (Figs 47–49, 156) Type specimens: Holotype ♂, China, Yunnan, Nujiang Lusi Autonomous Prefecture, 5 km S Fugong, road SS 228 km 223 (Salween River), 8.VI.2007, leg. Pütz (APCE). Paratypes (4 specimens): 1 ♂, 2 ♀, same data as holotype, but one specimen leg. Wrase (APCE, MFNB); 1 ♂, Laos, Xieng Khouang: 30 km NE Phonsavan (Phou Sane Mts) (19°38.2N, 103°20.2E), 1420 m, 10.–30.V.2009, leg. Brancucci (NHMB). Description: Macrophthalmous, pterodimorphous species with palisade fringe of abdominal tergite VII; specimen from Laos macropterous with elytral sutural length about as long as pronotum and functionary metathoracic wings; specimens from China micropterous with elytral sutural length about 0.8 times as long as pronotum and reduced, non-functional metathoracic wings. Body color medium brown or more contrasted with lighter brown pronotum and blackened elytra and abdomen; appendages light brown. Body surface subnitid with very fine, dense, setose punctation. Head about 1.1–1.2 times longer than wide with moderately convex temples and straight posterior margin. Eyes 0.43– 0.48 times as long as temples. Nuchal groove 0.27–0.3 times as wide as greatest head width. Trichobothrial cavity guttiform, with tapered anterior end connected to dorsoposterior margin of eye. Antenna from slightly elongate antennomeres 2 and 3 or 2–4 gradually wider toward moderately transverse penultimate antennomeres; antennomere 10 about 0.7–0.8 times, antennomere 11 about 1.4 times as long as wide. Total body length 2.3–2.6 mm; forebody length 1.4–1.3 mm. Male: Protarsomeres 1–4 dilated, approximately twice as wide as long. Abdominal sternite VII without diagnostic characters. Abdominal sternite VIII with subbasal ridge straight and posterior margin triangularly incised to approximately 0.1 of sternite length; lateral setae moderately long, up to about 0.25 times as long as sternite length (Fig. 156). Aedeagus with lobe-bearing apical portion occupying about 0.25 of aedeagal length (Fig. 47), in dorsal view long-oval, about three times as long as wide (Fig. 49); phallobase strongly extended beyond base of ventral process, there concave ventrally (Fig. 47) and laterally (Figs 48, 49) and with weakly set off ventrolateral sclerotization (Fig. 47). Apical lobes ventrally extended into large, subhyaline, subtriangular lobe (Fig. 47); in dorsal view, apical lobes with straight lateral margins slightly narrowed distad (Fig. 49). Dorsal lobe in lateral view straight dorsally with narrow, rounded apex (Fig. 47), in dorsal view long triangular with subacute apex (Fig. 49). Membranous portion (extension of apical lobes?) situated ventral of and reaching end of dorsal lobe, in lateral view with rounded apex (Fig. 47), in ventral and dorsal view subrectangular and protruding over dorsal lobe laterally (Figs 48, 49). Ventral lobe absent. Ventromedial endophallic lobe strongly projecting between ventral extensions of apical lobes, with strongly sclerotized distal margin and membranous proximal portion; distal margin of ventromedial endophallic lobe with two minute, distad pointing median denticles and acute apex (Fig. 47). Endophallic sclerites as in Figs 47, 49. Ventral process reaching ventral extensions of apical lobes, in lateral view thick, only weakly tapered toward blunt, moderately ventrad curved apex, and at widest point about 0.7 times as wide as aedeagus at same level (Fig. 47), in ventral view broadly sagittiform, at base about 0.6 times as wide as aedeagus at same level, and at widest point at about midlength projecting laterally over contour of aedeagus (Fig.48).Dorsomidlongitudinal split including dorsodistal opening occupying about 0.5 of length of phallobase (Figs 47, 49); latter therefore over same length collapsed in dry specimens (Fig. 47). Postforamen moderately projecting ventrad (Fig. 47). Circoforamen about three times as long as median foramen (Fig. 48). Length of aedeagus 0.3 mm. Length of aedeagus 0.37–0.4 mm. Female: Protarsomeres 1–4 not dilated, slightly wider than long. Distribution: Micranops sagittifer is recorded from the South Chinese province of Yunnan and northern Laos. Bionomics: In Yunnan, Micranops sagittifer was found on a moist embankment under stones. Etymology: The epithet sagittifer [adjective, Latin, composed of the noun sagitta (arrow) and the verb ferre (to carry)] refers to the—in ventral view—arrow-shaped apical end of the ventral aedeagus process of this new species.
