Nyctocalos is a genus of flowering lianas belonging to the family Bignoniaceae, and occurring from South-Central China to Malesia. In this study, we assembled the first complete chloroplast genome of N. pinnatum. The total length of the chloroplast genome is 159591 bp, with a GC content of 38.04%, which includes a pair of inverted repeats of 30,480 bp, a small single-copy region of 12,774 bp and a large single-copy region of 85,857 bp. The chloroplast genome contains 135 genes, consisting of 89 protein-coding genes, 38 transfer RNAs, and 8 ribosomal RNAs. We constructed a phylogenomic tree with representative chloroplast genomes from Bignoniaceae. N. pinnatum is revealed to be sister to Oroxylum in the tribe Oroxyleae, with a high bootstrap support. This is the first chloroplast genome assembled in Nyctocalos, and it provides essential information for further ecology and evolutionary studies in this genus and Bignoniaceae.
