Stenoloba rectilinoides sp. n.
( Figs 13 View FIGURES 1–15 , 40 View FIGURES 40–43 )
Type material. Holotype: male, China, Prov. Yunnan, Simao, Manxieba , 18.vi.2013, H.L. Han & C. Zhang leg., slide 2951-1, coll. NEFU.
Diagnosis. The new species is close to S. rectilinea and occurs in Southwest China sympatrically with the later. Together with S. rectilinea , they are members of S. rectilinea species group. Both species have a characteristic shape of the forewing with oblique costal margin in the basal part and almost parallel costal and ventral margins in the whole length of the wing; crosslines and spaces between lines appear in costal area as brown-greenish and brownish marks. Externally it differs from S. rectilinea ( Fig. 18 View FIGURES 16–30 ) by somewhat smaller size, paler general colouration of wing, more distinct basal field, subbasal and postmedial line and by presence of two distinct black marks in basal field. In male genitalia ( Fig. 40 View FIGURES 40–43 ) it differs from S. rectilinea ( Fig. 41 View FIGURES 40–43 ) by the shape of valva, which is more massive, with long sacculus, gradually constricted distally, tapered and rounded at apex (in S. rectilinea valva relatively shorter, with shorter sacculus, behind apex of sacculus constricted distally, but have quadrangular sacculus; the vesica of S. rectilinoides differs by longer tubular basal part and arming by sclerotised band, while in S. rectilinea vesica armed with patch of tiny setae-like cornuti.
Description. Adult ( Fig. 13 View FIGURES 1–15 ). Wingspan 24 mm. Head and thorax brownish with green, frons and collar brownish, marked with whitish. Forewing elongate, rather narrow, with basally arcuate costa and parallel costal and ventral margins. Ground colour of forewing pale brownish with green dusting, especially expressed in costal area; basal and subbasal fields separated from antemedial field by thin whitish line; basal field with two contrast black spots; Antemedial and postmedial lines thin, waved, indistinct; orbicular and reniform hardly traceable, slightly darker than background; postmedial line in tornal part of wing with pale-orange subtornal mark tinged with black; subterminal line as line of whitish spots tinged with dark brown; terminal line as interrupted row of blackish streaks; cilia brown, pale at base. Hindwing pale yellowish-grey suffused with dark scales basally, dark brown along terminal margin; discal spot and transversal line traceable; cilia brownish, with pale yellowish-grey base.
Male genitalia ( Fig. 40 View FIGURES 40–43 ). Male genitalia are similar to those of S. rectilinea . Uncus weak, short; tegumen narrow, vinculum rather broad, equal to tegumen in length; juxta broad, trapezoid; transtilla with broad sclerotised branches; valva massive (markedly more massive compared with S. rectilinea ), gradually constricted distally, tapered and slightly rounded at apex; sacculus much broader compared with S. rectilinea . Aedeagus elongate, vesica with extended tubular basal part, bulbous mid part beading short diverticulum with moderate flat cornutus; from ventral side it armed with narrow sclerotised band.
Female unknown.
Etymology. The species name S. rectilinoides refers to species similarity and affinity to closely related S. rectilinea .
Distribution. Southwest China (Prov. Yunnan). The species is known in China only from its type-locality Prov. Yunnan, Simao, where it occurs sympatrically and synchronously with S. rectilinea in mountains at elevation 1200–1500 m. Single male was collected in July.
