Argyreia pseudosolanum Traiperm & Suddee, sp. nov. from the NE region of Thailand is described and illustrated. The new species is remarkable in having a very distinctive corolla shape similar to Solanum, and staminal filament bases glabrous or nearly glabrous with a few multicellular, uniseriate hairs at the attachment point on the corolla tube. Detailed descriptions, illustrations, a summary of the ecology and an IUCN conservation status are provided.

Argyreia pseudosolanum Traiperm & Suddee
Diagnosis: Similar to Argyreia corneri in having a white rotate corolla, but differs in narrowly elliptic, oblong or lanceolate leaf shape (versus ovate), the ovate outer sepal shape (versus broadly ovate), the limb distinctly star-shaped with 5-triangular lobes (versus limb vaguely 5-angled).
Distribution and ecology: In mixed deciduous forest on a sandstone plateau. Elevation: 530 m.
Etymology: The specific epithet refers to the corolla shape, which is similar to Solanaceae and not found elsewhere in Argyreia.
Vernacular name: Khruea sawate phulangka (เครือเศวตภูลังกา), the name is given by the authors.
