Diagnosis. HL: 0.33–0.37 mm;PnL: 0.33–0.37 mm; PnW: 0.31–0.35 mm; EL: 0.45–0.57 mm; EW: 0.63–0.74 mm; T3L: 0.45–0.47 mm; AL: 0.59–0.86 mm; TL: 1.37–2.14 mm. Distinguishable from other Prespelea species only by the following characters: both sexes with strongly narrowed elytral humeri, presumably flightless, male metaventrite strongly projecting anteriad, apically truncate and slightly constricted medially ( Figs. 8, 9 ); male eyes with 6–10 ommatidia ( Fig. 4 ); male metatrochanters with distal tooth, acutely projecting anteriorly, basally wide ( Fig. 10 ); tergite 6 with lateral marginal carinae incomplete; female tergite VII (pygidium) shallowly depressed on either side of weak median carina ( Figs. 11, 12 ); apical margin of sternite VII produced, rugosely sculptured, distinctly dentate at

eyes, prominent metaventral process, and strongly narrowed elytral humeri. The female pygidium/terminal sternite complex is also Quite distinctive, with the rugose upturned borders and medial tooth of sternite VII, and the median ridge and lateral depressions of tergite VII (pygidium).
