Clematoscenea spinosus

description: Clematoscenea spinosus sp. n.
Male. Coloration (in alcohol). Body generally brown. Compound eyes grayish black; ocelli pale with dark brown ocellar field. Rest of head creamy brown with dark brown markings. Antennae dark brown except scape, pedicel and basal half of first flagellar segment yellowish. Maxillary palpus dark brown with basal segment lighter. Thorax brown, with dark brown spots. Legs with femora pale brown, tibiae and tarsi dark brown. Wings (Fig. 1): fore wing hyaline with brown markings: a band from hind corner of pterostigma to vein M+Cu1a, a band from fork of vein M and Cu1 to middle of vein 1A, and markings at distal third of cell R5; pterostigma dark brown. Hind wing hyaline, with brown markings in distal part of cell R; veins brown. Abdominal segments mostly dark brown.
Morphology. Head inverted triangular, with epicranial suture convex. Compound eyes ovoid. Antennae longer than fore wing. Fore wing membranous and glabrous; Sc ending free in membrane, Rs and M meeting at a point; pterostigma triangular with apex moderate round; distal closure of discoidal cell slightly concave; areola postica with very narrow apex, vein M3 parallel to Cu1a; radial fork branches diverge at an angle less than90°. Hind wing without marginal setae between R2+3 and R4+5. Abdomen ovoid. Phallosome (Fig. 4&5) a closed frame, longer than wide, with posterior margin concave medially. Hypandrium (Fig. 6&7) upturned distally and laterally to form a basin, posteriorly with ovoid lobe bearing irregular rows of spicules medially. Clunium (Fig. 8) with posterior margin convex medially and invaginated bilaterally. Epiproct (Fig. 8) roundly produced posteriorly, unsclerotized medially; paraproct broad, with slender apical spine, sensory field with about 42 trichobothria.
Measurements. Bw: 6412, B: 3825, FW: 5383, HW: 3753, F: 1099, T: 1533, t1: 473, t2: 264, f1: 1915, f2: 2105 (f3 missing), Mx4: 263, IO/d: 1.505.
Female unknown.
Material examined. Holotype male, CHINA: Yunnan Province, Menghai Co., Bulang Mountain, 27.iv.2011, Luxi Liu(CAU). Paratypes, CHINA: 2 males, Yunnan Province, Hekou Co., Nanxi To., 25.v.2009, Xiushuai Yang (CAU).
Distribution. China (Yunnan).
Etymology. The specific name refers to obvious spicules area in middle of hypandrium.
Remarks. The fore wing pattern of the new species is mostly similar to that of C. yunnanica, but the two species can be distinguished by the obvious pigmentation differences, as well as the genitalic differences. The hypandrium is similar to C. macalpinei Smithers & Thornton, C. mosomensis Smithers & Thornton and C. gressitti Smithers & Thornton, upturned distally and laterally to form a basin. However, the spicule pattern on the hypandrium is very different from that of the other three by lacking distal and lateral marginal-spicules.
