Figs 13–23, 47
Diagnosis
Salient features of new species include: forewings (Figs 13–14, 17) milk-white, clavus apex ½ to costal margin with broad brown marking, medial aera with 5 small round brown spots; lateral margins of medioventral process (Figs 19–20) nearly parallel in lateral view, apex with dentate process outward in ventral view; apical part of ventral lobe (Fig. 22) sac-like, lateral sides with 2 lamellar processes near middle; phallobasal conjunctival processes (Fig. 22) bent nearly 90 degrees toward back at apical part.
Etymology
The specific epithet is derived from the Latin word ‘ saccatus ’, referring to the sac-like apex of the ventral lobe of the phallobase.
Type material
Holotype
CHINA – Yunnan Province • ♂; Tengchong County, Jietou Town; 25°03′ N, 98°50′ E; 11 Aug. 2013; Wei-Cheng Yang leg.; IEGU.
Paratypes
CHINA – Yunnan Province • 1 ♂; same data as for holotype; IEGU.
Description
MEASUREMENTS. Body length including forewing: male 8.5–9.5 mm (N = 2).
COLORATION. General color milk-white to brown (Figs 13–14). Head and pronotum fuscous. Eyes reddish-brown, ocelli light red. Genae pale brown. Tegula and mesonotum light brown. Forewings milk-white, semihyaline, clavus apex ½ to costal margin with broad brown marking, ⅓ and apical part of costal cell each with large spot (former smaller than latter), with brown spot near MP bifurcation, apex of radial aera with markings, medial aera with 5 small round brown spots, between MP4 and MP5 with light brown stripe at terminal transverse vein, several irregular light brown to brown spots along veins near middle, veins gray. Hindwings nearly hyaline, veins pale grayish brown. Legs and abdomen brown.
HEAD AND THORAX. Head (Figs 13, 15) including eyes narrower than pronotum (0.5: 1). Vertex wider than long in middle line (3.2: 1), vertex concave, median carina absent, anterior margin angular convex in middle, posterior margin curved. Frons (Fig. 16) longer in midline than maximum width (1.9: 1), width at base narrower than width at apex (0.8: 1), median carina distinct, lateral margins concave. Postclypeus (Fig. 16) shorter in middle line than frons (about 0.66: 1), with weak median carina, lateral margins excavate. Pronotum (Figs 13, 15) longer in middle line than vertex (2.5: 1), median carina distinct, lateral carinae raised, not extending to posterior margin. Mesonotum (Figs 13, 15) about 3.9 × as long as pronotum in midline, longer than pronotum and vertex combined (2.8: 1), with weak median and lateral carinae. Forewings (Fig. 17) broadened apically, longer than maximal width (2.1: 1). Hindwings (Fig. 18) longer than widest part (1.4: 1).
MALE GENITALIA. Pygofer (Figs 19–20, 23) in lateral view with dorsal margin distinctly shorter than ventral margin, ⅓ of posterior margin strongly angulated caudad; in lateral view, lateral margins of medioventral process nearly parallel, apical margin truncate; in ventral view, apex of medioventral process with dentate process outward, apical margin wide and curved. Anal tube (Figs 19, 23) longer than widest part by about 1.1: 1 in dorsal view, apical margin broadly rounded, basal margin concave medially. Aedeagus (Fig. 22) symmetrical, phallobase in lateral view broad at base, dorsal lobe vestigial, lateral lobes narrowing apically, curving dorsad, with labial lobule near middle, dorsoventral margin of subapical segment slightly furled, angular at apex; ventral lobe shorter, with basal part constricted into stalk, apical part sac-like, lateral sides with 2 lamellar processes near middle. Phallobasal conjunctival processes bent nearly 90 degrees toward back at apical part, apical margin rounded, dorsal margin with lamellar process at curved region, lateral side with long and large ear-like process along ventral margin at apex. Gonostyli (Figs 19, 21) longer than wide, base narrow, apical margin broadly rounded, with stout twisted process rising from apical third of dorsal margin, inner side of base with slender, finger-like process.
Distribution
China (Yunnan province) (Fig. 47).
Remarks
This species is similar to Catonidia lii Chen & He, 2009, but differs from the latter as follows: (1) clavus of forewings apex ½ to costal margin with a broad brown marking (clavus of forewings apex ½ to costal margin without a broad brown marking in C. lii); (2) medioventral process in lateral view stout, apical margin truncate (medioventral process in lateral view slender, apical margin rounded in C. lii); (3) lateral sides of ventral lobe with 2 lamellar processes near the middle (lateral sides of ventral lobe without 2 lamellar processes near the middle in C. lii).
