Diagnostic description. Male (Fig. 38A, C). Greyish-black, shagreened; antennae and claws reddish brown. Body elongate, length 20.6–23.2 mm, width 7.5–8.3 mm, strongly convex. Head (Fig. 39E, J) with slightly smaller eyes, frontoclypeal suture less deeply U-shaped, width-length ratio of clypeus about 2.00; OI = 51.6–51.9. Antennae (Fig. 40D) slender, reaching basal third of elytra, with antennomeres weakly thickened to apices; relative lengths of antennomeres: 0.68: 0.34: 1.19: 1.10: 1.24: 1.28: 1.28: 1.19: 1.09: 1.02: 1.09. Pronotum (Fig. 39L) barrel-shaped, usually broader, sometimes nearly rounded, PW/PL = PW/PL = 1.21–1.23, lateral marginal borders thiner, visible in dorsal view along anterior third. Elytra elongate oval, EL/EW = 1.83–1.89. Protibiae (Fig. 40S) more markedly curved, pubescent of inner margins more developed and denser.

Female (Fig. 38B, D) distinctly stouter, length 19.4–23.3 mm. Distance between eyes wider, OI = 53.8–54.3, PW/PL = 1.18–1.26; elytra more convex, EL/EW = 1.60–1.64.

Variation. Some males have more roundly produced pronotal lateral margins; male spicula gastrale occasionally curving dorsally (Fig. 41J).

Comparative notes. Morphostenophanes furvus weishanus can be easily distinguished from the nominate subspecies by its much broader and more rounded male pronotum, and stouter female elytra.

Distribution. (Map 1) CHINA: Yunnan.

Etymology. The new subspecies is named after the locality the type series collected from, Weishan County.
