Typus: MADAGASCAR. Prov.Toliara: Gorges du Fiherenana, entre Beanty et Anjamala, [ 22°57’S 44°19’E], 30- 300 m, I.1947, fl., Humbert19902( holo-: P[ P05447658]!; iso-: [ P05447656, P05447657, P05447660, P05447661]!).
Conservation status. –With an EOO of 34,514 Km², and an AOO of 108 km² and nine subpopulations, two of which are within the protected area network (Beza Mahafaly and Tsimanampetsotsa) and one occurs in a proposed protected area which currently benefits from only temporary protection (Mikea Forest), S. keraudrenianais assigned a preliminary status of Least Concern (LC) following IUCN Red List Categories and Criteria ( IUCN, 2012).
Notes. – Socratina keraudrenianais unique in the genus in having the corolla tube not splitting unilaterally at anthesis but rather divided into five lobes in the distal part only, thus the tube is much longer than the corolla lobes ( BALLE, 1964a; Fig. 2A). The species is known from the south-western part of Madagascarin dry deciduous forests and xerophyte scrub, sometimes on limestone. Despite being a rather widely collected species, only two different hosts have been documented: Grewiasp. ( Malvaceae) (Du Puy & al. 699)and Mimosa delicatulaBaill. (Leguminosae) (Phillipson 2595) .
