Dietrich, Christopher H., 2025, Review of the Southeast Asian leafhopper genus Loeia Duan (Hemiptera: Cicadellidae: Deltocephalinae), Zootaxa 5666 (2), pp. 195-210 : 201-202

Loeia brevis sp. nov.

( Figures 1C , 2K–O )

Diagnosis. This species resembles L. cetacea in having the pygofer greatly elongated, but is easily distinguishable by the unusually short and laterally covex subgenital plates and the pair of curved spinelike ventral processes near the base of the aedeagus.

Description. Body length of male 5.2 mm (female unknown). Head in dorsal view with crown no longer medially than next to eye, 2.4× wider at base than medial length, anterior and posterior margins parallel. Male pygofer ~3.8× longer than maximum height, without ventral spine. Subgenital plate very short, lateral margin broadly convex, without concave distal section. Style relatively short, preapical lobe weakly developed, apex digitiform, curved slightly laterad. Aedeagus with dorsal apodeme relatively short and broad, shaft tubular, with pair of large posteriorly curved ventral processes arising near base (distal part of shaft broken off and missing in only available specimen).

Etymology. The species name refers to the unusually short subgenital plate.

Material examined. Holotype male, THAILAND Petchaburi , Kaeng Krachan NP Panernthung /km27, 12º49.302'N 99º22.263'E, Malaise trap 4–11.ii.2009, Sirichai leg. T4412 [ QSBG].
