Abstract
In this study, we describe the macropterous forms of Nocticola uenoi uenoi Asahina, 1974 and Nocticola uenoi kikaiensis Asahina, 1974, which have previously not been described in detail, and describe a new species in the genus Nocticola umedai sp. nov. Yanagisawa & Ohgita, collected in Nagasaki Prefecture, Japan. Two forms of this species were identified, namely, a yellowish macropterous form with yellow body color and reduced compound eyes, and a brownish macropterous form with brown body color and developed compound eyes. The yellowish macropterous form can be distinguished from similar species with respect to 1) development of both tegmina and wings of male; 2) L4C long and hook-like; 3) L1 left posterior corner long and spine-like with corrugated and right side with rounded square base and long spine extending from posterior margin, whereas the brownish macropterous form 1) sharply pointed L4C apex; 2) supraanal plate close to quadrangle; 3) subgenital plate asymmetrical; 4) L1 with long projections on either side. We also provided an updated version of the key to macropterous Nocticola previously presented by Lucañas and Maosheng (2023).
