Description
Length of male 7.1–7.3 mm, female 9.4 mm. Crown with marginal rim black ventrally, but anterodorsal part of frontoclypeus pale ochraceous; middle and hind femur without black spot on anterior surface of apex. Crown shorter than pronotum, anterior margin broadly rounded. Hind tibial rows PD, AD and AV with 17–20, 14 and 13–15 macrosetae, respectively. Male pygofer with large semicircular ventral lobe near midlength, just basad of membranous cleft separating distal part of lobe. Style apophysis slender throughout, somewhat sinuate, rugulose ventrally, apex slightly broadened, rounded ventrally and with short, acute tip dorsally. Connective with anterior margin truncate. Aedeagus with atrium ovoid, with short, distinctly separate, broadly V-shaped dorsal connective; shaft slender, tubular basally, curved dorsad, gonopore preapical on posteroventral surface; apical extension of shaft compressed, forming continuous curve with rest of shaft, rounded apically in lateral view; with two pairs of ventral processes arising from base, one pair large, compressed and broadened distally in ventral view, with tapered apices extended beyond shaft apex, only slightly divergent from shaft in lateral and ventral views, second pair dorsad of and partly enclosed by first pair, slender and curved slightly dorsad distally, slightly shorter than shaft. Female abdominal sternite VII with slight median notch.
Remarks
This species is less robust than the other two species of the genus and also differs in having the aedeagal processes closely adjacent to the shaft and the transverse striations of the crown very weakly developed.
