Recently, new species of Paphiopedilum have discovered from Laos and descrived. Now other species descovered newly from Laos descrived as a new species , Paphiopedilum papilio-laoticus on OrchideenJournal Vol.6-4, 5 June 2018, by Andre Schuiteman, Sulvng Luang Aphay and Shunsuke Iio.
In this description, the auther said ' Unfortunately, commercial plant collectors rather than scientists may be the first to come across such new species, and these may end up in heaps of plants sold on local markets. The species described in this paper came to light in this way. In the interest of conservation, we refrain from disclosing locality and habitat information. This showy and undoubtedly very rare species will hopefully be propagated from seed soon, and we urge orchid amateurs not to buy any plants of this species that could be wildcollected. In a few years‘ time it should become widely available as legally propagated plants that do not pose a threat to its continued existence in the wild.
    
Flower c. 12 cm across. Dorsal sepal suborbicular, held almost fl at upright, 8.4 × 8.6 cm, apex emarginate, mucronate. Synsepal narrowly ovate, 6.8 × 3.1 cm, subacute. Petals widespreading to somewhat incurved, narrowly oblanceolate, 7.7 × 1.8 cm, apex rounded, margins slightly undulate, at base below the midvein with a small patch of long hairs, at apex slightly pubescent. Lip 6.5 × 3.9 cm; claw 2.1 cm wide, staminode ovate, 1.2 × 1.0 cm.
Paphiopedilum papiliolaoticus seems most similar to the highly variable P. gratrixia num (incl. P. daoense (Aver.) Aver. & O. Gruss; Averyanov et al., 2017) but differs in the much larger fl owers (dorsal sepal 8.6 cm wide versus 4.4–4.6 cm), the uniformly pubescent, white staminode with incurved margins (staminode only partly pubescent, brownish yellow, without incurved margins), and the eyelike purple spots on the dorsal sepal (solid maroonpurple spots in P. gratrixianum). The only other species in sect. Paphiopedilum with a white staminode and the nearest in the size of the dorsal sepal is P. charlesworthii, but in that species the staminode is glabrous and the dorsal sepal is uniformly pinkish with darker veins, 4.7–6.6 cm wide (Cribb, 1998).
From all other species in the section it also differs in the much larger fl owers, the white staminode, and in the unique colours of the dorsal sepal: white fl ushed light purple with a yellowgreen blotch at the base and with prominent purple spots that have a lighter centre, like the eye spots on the wings of certain butterfl ies.
