Holotype male, Laos : Vientiane (Wieng Jan) Prov., National Park Phu Khao Khouay, Ban Vangheua, elevation = 800 m , 18°20.102'N , 102°48.983'E , pitfall & carrion trap, mixed bamboo forest, 27 February–28 March 2008 , coll. S. Tarasov. Originally M. laosana was assigned to the genus Neostylopyga , with the comment that this species and N. rhombifolia (Stoll) , the type species of the genus Neostylopyga , probably belonged to different genera (Anisyutkin 2010). The original description (Anisyutkin 2010) can be supplemented with the following details. Description . Male ( holotype ). Tibiae not thickened distally, apical spines not reinforced. Metatarsus of hind tarsi ( Figs. 25, 26 ) slightly longer than other segments combined, with 2 rows of spines along lower margin (exterior row with 16–19 spines, interior row with 11–12 spines); second segment with 4 spines in exterior row and single spine corresponding to interior row on left tarsus; all segments with small apical euplantulae bordered with 2 additional spines ( Fig. 25 , a.s. ); claws symmetrical, simple; arolium vestigial. Left hind tarsus abnormal, with 4 segments. Fore and middle tarsi similar to hind tarsi, but comparatively shorter; fore and middle metatarsi with 14/ 8 and 12/7–8 spines in exterior/interior rows respectively, second segment of left middle tarsus with single spine along lower margin; other segments without armament along lower margin.
