ABSTRACT
Microchirita (C.B.Clarke) Yin Z.Wang (Gesneriaceae: Didymocarpoideae) in Thailand is revised and 29 species are recognised, two of which have three varieties each. Eight new species are described, Microchirita albocyanea C.Puglisi, Microchirita glandulosa C.Puglisi, Microchirita hypocrateriformis C.Puglisi, Microchirita limbata C.Puglisi, Microchirita luteola C.Puglisi, Microchirita tadphoensis C.Puglisi, Microchirita tetsanae C.Puglisi, Microchirita thailandica C.Puglisi; three new varieties are described, Microchirita involucrata var. gigantiflora C.Puglisi, Microchirita mollissima var. glabra C.Puglisi, Microchirita mollissima var. glandulophylla C.Puglisi; and one name is combined at a new rank, Microchirita involucrata var. capitis (Craib) C.Puglisi. Two lectotypifications are made, one of which is a second step lectotypification. A key to all taxa is given, all taxa are described, and many are illustrated.

15. Microchirita luteola C.Puglisi, sp. nov.
Similar to Microchirita tubulosa (Craib) A.Weber & D.J.Middleton but differs in not having spots inside the lateral corolla lobes, having an entire disk (usually dorsally cleft in M. tubulosa), glandular indumentum on the stems (vs. eglandular), and acuminate calyx lobes (vs. usually acute, more rarely slightly acuminate). It is also similar to Microchirita marcanii in the shape of the corolla, but differs in the mixed eglandular and glandular indumentum on many plant parts (eglandular only in M. marcanii (Craib) A.Weber & D.J.Middleton) and the corolla colour pattern (light yellow corolla with a yellow stripe vs. orange corolla with lateral purple spots). Finally, it differs from Microchirita elphinstonia (Craib) A.Weber & D.J.Middleton in having a glandular indumentum and in the larger and much paler yellow corolla.
