Type material.
Holotype: ♂, Xinping County, Mt Ailaoshan, Yunnan Province, China (101°57'57"E, 24°07'39"N; 1956 m elev.), 22 July 2018, coll. Xianyi Wang & Jiajia Wang. Paratypes: 58♂♂ 2♀♀, same as holotype. 4♂♂, Lvchun County, Mt Hoanglianshan, Yunnan Province, China (102°17'27"E, 22°56'03"N; 1815 m elev.), 7 June 2019, coll. Jiajia Wang & Chao Zhang. 1♂, Baoshan City, Mt Gaoligongshan, Yunnan Province, China (98°48'03"E, 25°18'15"N; 1581 m elev.), 22 May 2019, coll. Jiajia Wang & Chao Zhang.
Diagnosis.
This new species resembles Idioscopus furcaprocessus in general appearance, including having a yellow patch on the forewing clavus. The sinuate shaft of the aedeagus in lateral view is similar to I. confuscous (Pruthi) (see Viraktamath, 1980: fig. 15), I. bihamulus , I. recurvatus , and I. nitellicus , but it differs from these and other species in having an unpaired, ventral, spine-like process proximad of the midlength of the shaft.
Description.
Coloration. General color reddish brown. Crown yellowish with darker reddish-brown markings; eyes yellowish (Fig. 2A-C View Figure 2 ). Pronotum and mesonotum (Fig. 2A View Figure 2 ) reddish brown, mesonotum paler with yellowish hue. Face (Fig. 2B View Figure 2 ) greenish yellow with frontoclypeus and anteclypeus pale reddish brown; male antennae with apical disc, black. Mesepimeron (Fig. 2C View Figure 2 ) with black patch. Forewing clavus (Fig. 2A View Figure 2 ) with large, lemon-yellow patch bordered with dark reddish brown.
External features as in generic description with head and thorax shagreen; male antennae with apical disc (Fig. 2A-C View Figure 2 ); forewing (Fig. 2D View Figure 2 ) with two subapical cells, inner subapical open.
Male genitalia. Male pygofer (Fig. 2E, F View Figure 2 ) conically rounded apically, without ventral process; anal collar thin, upturned apically; dorsoanterior apodemes well developed. Anal tube (Fig. 2E View Figure 2 ) long. Subgenital plates (Fig. 2E View Figure 2 ) broader in distal one-third in lateral view, longer than pygofer, sharply upturned in basal third, with long hair-like marginal setae distally. Connective (Fig. 2G View Figure 2 ) Y-shaped, broad, with short stem. Style apophysis (Fig. 2G View Figure 2 ) narrowed to apex with weakly serrated inner margin. Aedeagus (Fig. 2H, I View Figure 2 ) with shaft laterally compressed, broad in basal half then narrowed and slightly sinuate distally to acute apex in lateral view, with one pair of subapical bifid processes, each fork unequal, an unpaired ventral spine-like process proximad of midlength; dorsal apodeme laterally compressed, distally expanded in lateral view and laterally expanded distally in ventral view.
Female genitalia. Posterior margin of sternite VII (Fig. 3F View Figure 3 ) slightly produced medially. Valvulae as in Figure 3G-J View Figure 3 .
Measurements (mm).
Male: body length including tegmina 4.50-4.95. Medial length of crown 0.18-0.22, width 1.55-1.60. Distance from ocellus to eyes 0.15-0.20. Medial length of pronotum 0.45-0.48, width 1.35-1.45; scutellum length 0.50-0.55, width 0.65-0.70. Female: body length 4.60-5.20 including tegmina.
Etymology.
The new species name is derived from the words ventri - and spinus, referring to the ventral spine-like process of the aedeagal shaft.
Host plant.
Myrica sp.
