Discusión taxonómica

(In relation to the synonym Lellingeria delitescens) See discussions under Lellingeria prionodes and L. limula for comparison with those species which are closely related. All Chiapas specimens cited as Grammitis delitescens by Smith (1981) are here referred to either Lellingeria limula or L. prionodes. Also, specimens identified as L. delitescens from Guatemala (Stolze, 1981) are mostly L. prionodes; the sole specimen cited by Lellinger from Panama (Valdespino et al. 268, US) is L. myosuroides, and the Costa Rican one is likely also misidentified. Thus, the species appears to be absent from Central America.A
