Genus Favintiga Webb, 1981

Favintiga Webb, 1981: 47 ; Zhang & Webb, 1996: 14; Shang, Zhang, Shen & Li, 2006: 35; Dai, Qu & Yang, 2016: 396; Lu & Zhang, 2018: 446 .

Type species: Parabolopona camphorae Matsumura, 1912 , by original designation.

Description. This genus can be identified by the following characters: body small-sized with coloration yellowish brown; hind margin of crown with a pale yellow spot on each side of coronal suture; ocelli reddish; forewing marked with small brown spots at apex of claval suture, A1 and A2 veins, m-cu1 cross vein, base of M3+4 vein and periphery of apical cells.

Crown with fore margin triangularly produced, median length about two times as long as next to eyes, middle region with fine longitudinal stripes, coronal suture extending higher than mid-length of vertex, anterior margin transversely striate or carinate medially; ocelli on anterior margin of head, distant from eyes, visible dorsally, approximately three to four times their own diameter from corresponding eyes; anterior tentorial branches curved and long anteriorly (L-shaped), not bifurcate; face long; frontoclypeus long and narrow, shagreen, slightly constricted apically; anteclypeus strikingly expanded distally; lorum broad, subequal to or narrower than anteclypeus near base; gena with oblique wrinkles; antennae longer than half of body length, antennal bases at upper corners of eyes in facial view, antennal pit moderately deep and antennal ledge strong; head nearly as wide as pronotum; pronotum with fine wrinkles and sparse punctations, lateral margin moderately long, carinate, hind margin slightly concave; forewing with inner subapical cell open, the cross vein present between claval suture and A1, appendix narrow; fore femur with anteromedial (AM1) row seta long and stout, intercalary (IC) row with about 11–15 fine long setae, anteroventral (AV) row setae nearly vestigial; protibia with 1+4 dorsal setae; metafemur with apical setal formula 2+2+1 or 2+1+1.

Male genitalia: pygofer side with numerous macrosetae and several microsetae, caudal margin rounded or produced, ventroposterior margin without appendages; valve rectangular or triangular; subgenital plate wide basally, lateral margin strongly narrowed near the middle, with several short fine setae on base, apical process long and finger-like with a few short setae distally; style with apical process pointed, beak-like, lateral lobe prominent or not, with a few short fine setae; connective Y-shaped, stem extended posteriorly, apex unevenly bifurcated or with a long process apically on ventral surface, process distally bifurcated or not; apex of connective stem articulated with aedeagus or linked to aedeagus by membrane; aedeagal shaft curved dorsad, apically tapered, ventroposterior margin with a pair of basal processes, dorsal atrium developed, gonopore situated at apex on posterior surface; anal tube moderately long, cylindrical.

Female genitalia:ovipositor strikingly exceeding apex of pygofer; dorsal margin of first valvulae with sculpturing pattern strigate, with irregular fluctuation from near middle to subapical, apex narrow; second valvulae with a dorsal middle blunt tooth, dorsal margin with serrate teeth restricted to approximately apical one-third.

Distribution. China, Japan.

Remarks. This genus is externally similar to Parabolopona but the head has the anterior margin transversely striate rather than with a single transverse ridge; the connective stem has a long process apically on the ventral surface extended posterad below the aedeagus; the apex of the connective stem is articulated with or linked to the aedeagus by a membrane rather than the aedeagus being linked to the connective by a membrane near the midlength of the connective stem.
