03D5831CFFF8FFE7F914FBACBD2AE655.taxon	biology_ecology	Host plant and habitat The type series was collected by beating shrubs on a warm and sunny day, in a sparse semi-arid shrubland on a coarse, stony substrate of a montane limestone plateau (Fig. 10 A – B). The vegetation was almost uniformly composed of Croton cf. socotranus Balf. f. (Euphorbiaceae). This plant species is thus a probable host of M. caudata gen. et sp. nov. (Fig. 10 C).	en	Świerczewski, Dariusz, Malenovský, Igor, Stroiński, Adam (2018): Medleria gen. nov. adds to the biodiversity of Flatidae (Hemiptera: Fulgoromorpha) in the island of Socotra.
