23. Mecyclothorax parovalipennis Perrault, 1988: 236

Identification.

Like Mecyclothorax ovalipennis , this species is characterized by rounded hind angles that are bordered anteriorly by a slightly sinuate lateral margin (Figs 20A, B). The discal elytral striae are basally punctate, the punctures elongate and laterally expanding the striae, and the discal elytral intervals are nearly flat, even depressed in association with the microsculpture over portions of the intervals (Fig. 20B). The microsculpture is more well developed than in Mecyclothorax ovalipennis , with: 1, the frons bearing patches of transverse-mesh microsculpture and the neck impression with well-developed isodiametric sculpticells; 2, the pronotal disc covered with a shallow but evident transverse mesh; and 3, the discal elytral intervals lined with distinct transverse microsculpture comprising areas ranging from slightly transverse sculpticells to areas of transverse lines. The male aedeagal median lobe apex is broader than that of Mecyclothorax ovalipennis (Fig. 19B, C), and the apical face is more flattened. Setal formula 2122; standardized body length 5.9 mm.

Distribution and habitat.

This species is known only from the two type specimens collected at 1900 m elevation near the summit of Mont Aorai.
