Differential diagnosis

The male of this new species resembles that of M. echinatus Wang, 1990 ( Wang 1990: figs 3B–C, 4A–B; Zeng et al. 2016: figs 1B–C, 2A–B), but can be distinguished from the latter by: 1) vexillum of cymbium handle-like in retrolateral view ( Figs 3D View Fig , 4B View Fig ) versus sheet-like in M. echinatus ( Zeng et al. 2016: figs 1B–C, 2A–B); 2) apex of cymbium without macrosetae ( Figs 3 View Fig C–D, 4A–B) versus present in M. echinatus ( Zeng et al. 2016: figs 1B–C, 2A–B). The female of the new species resembles that of M. labiatus Wang, 1990 ( Yin et al. 2012, figs 53C–D), but can be distinguished from the latter by: 1) scape of epigyne subtriangular in ventral view ( Figs 3F View Fig , 4C View Fig ) versus almost trapezoid in M. labiatus ( Yin et al. 2012: figs 53c–d); 2) spermathecae round in dorsal view ( Figs 3G View Fig , 4D View Fig ) versus oval in M. labiatus ( Yin et al. 2012: figs 53c–d).

Etymology

The specific name refers to the type locality: the Lingbaoshan National Forest Park.
