Amiota (Amiota) kimurai sp. nov.

(figure 5)

Diagnosis. Paramere about 1.3 times as long as aedeagus, strongly sclerotized and as thick as aedeagus at apex (figure 5E).

Description. Ocellar triangle and upper three-quarters of frontal vitta velvety brownish black; lower one-quarter of frontal vitta orange brown. Gena orange brown.

Legs: Mid tarsus with two rows of minute, cuneiform setulae on posteroventral surface. Hind trochanter with one dark brown, lobe-shaped process.

Abdominal sixth tergite tapered laterally, broadened dorsally.

Male terminalia: Epandrium small, constricted more than one-half width middorsally, with 15–17 setae near posterior to ventral margins (figure 5A). Surstylus lacking pubescence, with fi nger-like process at posteroventral corner, and about seven prensisetae on distal margin (figure 5B). Tenth sternite deeply constricted midventrally, but not separated, entirely fused to surstyli laterally; lateral lobe-like process elongated, curved (figure 5B). Anterior portion of hypandrium slightly broadened, and invaginated (figure 5C). Aedeagus basally fused to paramere figure 5E). Ejaculatory apodeme: apical plate with four pits per side; stalk curved medially (figure 5F).

Female: Sixth sternite notched on posterior margin; seventh tergite separated mid-dorsally, pubescent only on posterior margin; eighth sternite lacking pubescence; pregenital lamella semitube-like (figure 5G).
