Additional material.

1 ♂ (NWUX), "NW China: Shaanxi, Xunyangba, Ningshaan , 33.55°N, 108.55E °, 20.v-23.vi.2016, g[reen] Malaise trap, 1481 m alt., JL Tan & QQ Tan, NWUX" .

Distribution.

China (Henan, Hubei, Shaanxi, Zhejiang).

Notes.

The male from Baolongyu (Qinling Mts, Shaanxi) illustrated by Tan et al. (2016) is the male of G. granulatum sp. nov. It differs from typical G. angulatum males because the middle lobe of the mesoscutum is less protruding and very regularly granulate (Figs 118 and 119 ) and the hind coxa is somewhat less slender (Fig. 120 ) than normal for G. angulatum . The male, listed above, was collected later and agrees better with the type series. This male has the middle lobe of the mesoscutum distinctly protuberant (Fig. 30 as in fig. 20 in Zhao et al. 2012) and very slender hind coxa (Figs 27 and 36 , as in fig. 23 l.c.).
