Pediopsoides (Glaphyropsis), Okudera & Hayashi, 2024

Okudera, Shigeru & Hayashi, Masami, 2024, Two new species of the macropsine leafhoppers (Hemiptera: Cicadellidae: Eurymelinae) from Japan, with description of a new subgenus, Zootaxa 5418 (2), pp. 172-182 : 175

Glaphyropsis subgen. nov.

Type species: Pediopsoides (Glaphyropsis) aurantescens sp. nov.

Head slightly narrower than pronotum; face width across eyes slightly shorter than length, and slightly swollen in lateral view; male lorum narrow; ocelli about 5 times closer to adjacent eyes than to each other; space between coronal pits as wide as ocelli; crown rounded in dorsal view. Pronotum about twice as wide as long in median line, with transverse striae; anterior margin of pronotum not extending forward between eyes, shallowly concave posteriorly. Mesonotum slightly longer than pronotum. Hind femoral macrosetae 2 + 1, hind tibial with 8 to 11 macrosetae on AD row, 5 to 6 on AV row, 9 to 12 on PD row. Forewing with two anteapical cells and four apical cells.

Male genitalia. Pygofer lobe elongate with three or four short inner spines near ventral margin. Subgenital plate slender with short hairs on almost entire surface. Style slender, nearly 0.7 times as long as subgenital plate, with preapical bearing uniseriate short setae along dorsal margin, and with apophysis bent dorsad. Dorsal connective broadly fused with tenth segment; ventral part slender and recurved in lateral view; dorsal part with a pair of large process near apex of tenth segment. Aedeagus slender and nearly straight with dorsal apodeme as thick as shaft in lateral view; gonopore situated apical or slightly ventral.

Distribution. Japan, China.

Etymology. The subgenus name Glaphyropsis is formed by combination of the Greek word glaphyros, meaning “smooth”, and opsis, the Greek noun for forehead appearance or facial features.

Remarks. This new subgenus is similar to Pediopsoides (Pediopsoides) in having rounded anterior margin of the head, and two anteapical cells on the forewing. However, it differs significantly from subgenus Pediopsoides in the dorsal connective of male genitalia fused with tenth segment. Pediopsoides (Glaphyropsis) and Celopsis have common characteristics in dorsal connective fused with tenth segment, but P. ( Glaphyropsis ) differs from Celopsis in the dorsal connective much broadened and situated near apex of tenth segment. Furthermore, P. ( Glaphyropsis ) can be distinguished from Celopsis by three other features: rounded anterior margin of the head, transverse pronotal striae, and two anteapical cells of forewing. Four described species of Celopsis , C. membrana (Zhang) , C. montaninversa (Yang & Zhang) , C. trifurcata (Li, Dai & Li) and C. rhombica (Li, Dai & Li) are newly transferred to this subgenus.
