Genus Fangamanus , gen. n.

( Figs 116–177 )

Type species: Parabolocratus tripunctatus Matsumura 1915: 170 .

Description. Colour. Yellow-green to slightly brown. Vertex margin with transverse submarginal ventral fuscous line. Orange or yellow fascia, a short round convex lines in the middle on pronotum, 3 longitudinal lines on scutellum before transverse depression, sometimes faint or absent. Forewing with 2 well-marked dark or brown spots, one each at the end of Cu and R 2+3, R 1 reflexed and usually darkly pigmented. Hind wings hyaline, veins brown.

Body. 3.4 to 6.5 mm in length. Anterior tentorium slender, furcate ( Fig. 185 ). Vertex slightly upturned anteriorly. Ocellus close to corresponding eye. Pronotum slightly wider than head. Profemur ( Fig. 186 ) with 12–16 AV (anteroventral) setae and two apical dorsal setae; intercalary row with 9 setae; AM1 seta (anteromedian) present. Hind tibia compressed; first tarsomere with 7 teeth in two rows on plantar surface, 5 platellae and 2 terminal lateral spines at apex; second tarsomere with 4 teeth on plantar surface, 2 platellae and 2 terminal lateral spines at apex; hind femoral setal formula 2-2-1. Forewing R and M fused basally, m-cu 2 absent; clavus with two complete and separate veins; appendix narrow and long, extending beyond end of M 3+4; 1 or 2 reflexed crossveins arising from outer margin of outer anteapical cell in costal area; rounded apically.

Male genitalia: Valve broadly triangular, laterally articulated with pygofer. Subgenital plates dorsoventrally flattened, nearly right-angled triangle, tapering apically, 3–5 setae laterally. Pygofer side with distinctive ventral lobe, heavily setose in posterior 1/2. Connective U-shaped. Style subtriangular, dorsoventrally flattened. Aedeagus with 1 or 2 pairs of terminal processes; aedeagal shaft minutely and irregularly toothed ventrally; gonopore subapical in ventral groove; dorsal apodeme developed.

Female genitalia: Ovipositor extending beyond pygofer; first valvulae ( Fig. 190 ) broad, knife-shaped; sculpturing pattern on first valvula granulose, submarginal; first valvula with distinctly delimited ventroapical sculptured area; second valvulae ( Fig. 192 ) bladed, wide and short, humped in middle, dorsally fused 1/2 basally; second valvulae lacking dorsal teeth ( Figs 193 ). Seventh sternum with medial projection and slight notch at each side.

Distribution. Oriental Region.

Etymology. The genus name, a masculine noun, is derived from the Chinese pronunciation of “group with reflexed crossvein(s) in costa of tegmen”.

Remarks. This genus resembles Linnavuoriella in having a similar colour pattern dorsally, but the latter is larger, has the forewing without a reflexed crossvein, a single claval vein, the aedeagal shaft smooth, without groove and ridge ventrally and the gonopore located at the anterior 1/3 of the shaft ventrally.

The following three species from the Oriental Region are transferred from Hecalus to this genus according to their original descriptions and material examined (see below): Hecalus rufofascianus Li 1990 ( China) , Hecalus morrisoni Kwon and Lee 1979 ( Korea) , and Hecalus tripunctatus ( Matsumura 1915) ( Japan, Korea, Russia, and China). Hamilton (2000) assigned H. rufofascianus to the genus Linnavuoriella based on its colour pattern, but this species is different from the type species of Linnavuoriella in many respects (noted above), including the female valvulae. Hamilton (2000) placed H. morrisoni and H. bifidis Dash & Viraktamath 1997 ( India) in Memnonia . The former species is included in Fangamanus here based on figures provided by Kwon and Lee (1979) which conform to the genus as described here. Specimens of the latter species were not examined in this study, but this species may warrant placement in the new genus, pending further examination.
