(Figs. 7, 8, 18)

Pseudovelia intonsa Hecher, 1997: 42 .

Material examined. VIETNAM, Quang Binh Prov., 6 apterous males, 8 apterous females, Minh Hoá district, Tan Hoá (17°46'N, 106°05'E), 29.V.2015, coll. Zhen Ye (NKUM).

Remarks. Hecher (1997) gave an excellent description including line drawings and scanning electron microscope (SEM) photos of this species. We collected this species on the muddy shore along a relatively wide stream (Figs. 14–17). The specimens could quickly leave the shore when disturbed and then quickly return to the muddy shore after a while.
