Figs 1–13 View FIGURES 1–13
Measurements. Length (including forewing): male 3.0–4.3 mm (N = 4), female 3.7–4.5 mm (N = 9).
Diagnosis. The salient features of the new species include: frons ( Fig. 4 View FIGURES 1–13 ) centrally with an inverted chevron shaped dark mark; forewing ( Fig. 5 View FIGURES 1–13 ) with CuA 1 obviously convex distad of clavus, reaching MP; medioventral process of pygofer ( Fig. 11 View FIGURES 1–13 ) constricted abruptly at end, apical margin rounded and convex in ventral view; aedeagus ( Figs 12, 13 View FIGURES 1–13 ) asymmetrical bilaterally, ventral lobe cleft medially, each side of midline with two dentate processes at proximal part; gonostyli ( Fig. 9 View FIGURES 1–13 ) with three processes along the lateral margin.
Coloration. General color yellowish white to fuscous ( Figs 1–2 View FIGURES 1–13 ). Vertex ( Figs 1, 3 View FIGURES 1–13 ) yellowish brown with 2 long fuscous stripes along midline. Frons ( Fig. 4 View FIGURES 1–13 ) yellowish white, with an inverted chevron shaped marking, lateral carinae with 3 brownish black transverse bands. Clypeus ( Fig. 4 View FIGURES 1–13 ) yellowish brown. Genae ( Fig. 2 View FIGURES 1–13 ) yellowish white, with 3 fuscous transverse stripes before eyes (2 above and 1 below ocelli), 1 short transverse stripe dorsad, area beneath antenna with a fulvous marking. Eyes brown, ocelli reddish-brown. Antennae yellowish brown to brown. Pronotum ( Figs 1, 3 View FIGURES 1–13 ) yellowish brown, longitudinal carinae yellowish white, lateral areas with 4 fuscous spots, middle area yellowish-white to yellowish-brown. Mesonotum ( Figs 1, 3 View FIGURES 1–13 ) yellowish brown, with multiple large or small brown to fuscous markings. Tegula yellowish fuscous. Forewings ( Fig. 5 View FIGURES 1–13 ) pale brown to brown, many white spots scattered, most of them near veins, with narrow brown markings along veins, callus blackish brown, tinged with reddish orange margin. Hindwings ( Fig. 6 View FIGURES 1–13 ) pale brown, veins brown. Abdomen fuscous, lateral margins brown.
Head and thorax. Head ( Figs 1, 3 View FIGURES 1–13 ) narrow. Vertex medially longer than wide at base (1: 0.71), disk depressed, apex slightly acute, anterior margin slightly truncate, posterior margin sinuate, median carina distinct, lateral carinae strongly ridged. Frons ( Fig. 4 View FIGURES 1–13 ) near rhomboid, longer in midline than wide at widest portion (about 1.13: 1), median carina with basal half obsolete, lateral margins strongly foliate. Rostrum with apical and subapical segment equally long. Pronotum ( Figs 1, 3 View FIGURES 1–13 ) short, in midline shorter than vertex (0.61: 1). Mesonotum ( Figs 1, 3 View FIGURES 1–13 ) longer in midline than vertex and pronotum combined (1.60: 1). Forewings ( Fig. 5 View FIGURES 1–13 ) slender, longer than maximum width (2.51: 1), CuA 1 obviously convex distad of clavus, reaching MP. Hindwings ( Fig. 6 View FIGURES 1–13 ) longer than widest part (1.7: 1). Hind tibiae with one lateral spine.
Male genitalia. Pygofer ( Figs 10, 11 View FIGURES 1–13 ) in lateral view, gradually widened from the back to the abdomen, anterior margin strongly concave in the middle, posterior margin with a short angular process near the middle; in ventral view, medioventral process stout, constricted abruptly at end, apical margin rounded and convex. Anal tube ( Fig. 7 View FIGURES 1–13 ) in dorsal view length nearly equal to width, apical margin emarginate medially, anal style slightly extending out apical margin of anal tube.Aedeagus ( Figs 12, 13 View FIGURES 1–13 ) longer than phallobase (2.50: 1), asymmetrical bilaterally, tubular, membranous, divided into 4 lobes at apex; in ventral view, lateral margins with two and one angular processes, middle part with a thick spiny process, directed basad, ventral lobe cleft medially, each side of midline with two dentate processes at proximal part; in dorsal view, dorsal lobe rounded and convex at apical part, left side with 5 spines at basal half, right side with 3 spines. Gonostyli ( Figs 8, 9 View FIGURES 1–13 ) bow-shaped, apex curved inward, apical margin emarginate; in dorsal view, lateral margin with inverted fingerlike, large hornlike and short rounded processes at 4/5, 2/3 and 2/5 of the proximal part, respectively.
Type material. Holotype: ♁, CHINA: Laoshan, Qingdao , Shandong Province, 16 August 2011, Jian-Kun Long ; Paratypes: 3♁♁, 9♀♀, Laoshan, Qingdao, Shandong Province, 16–17 August 2011, Jian-Kun Long .
Etymology. The specific name is derived from the Latin adjective “ dentatus ”, referring to the number of dentate processes on each side of midline of phallobase.
Remarks. This species is similar to Deferunda rubrostigmata ( Matsumura, 1914) , but differs from the latter in: (1) vertex yellowish brown (vertex milk-white in D. rubrostigmata ); (2) medioventral process of pygofer constricted abruptly at end, apical margin rounded and convex (medioventral process of pygofer tapering apically, apex angular in D. rubrostigmata ); (3) gonostyli with three processes along the lateral margin (gonostyli with single process medially in D. rubrostigmata ); (4) ventral lobe of aedeagus each side of midline with two dentate processes at proximal part (ventral lobe of aedeagus each side of midline with one dentate process at proximal part in D. rubrostigmata ).
Distribution. China (Shandong) ( Fig. 40 View FIGURE 40 ).
