Diagnosis. Length of forewing is 11 mm in males and 14–14.5 mm in females. The new species is very similar externally to N. melli sp. nov. and N. angkorensis , and differs only in the broader posterior section of the medial line. In many cases a reliable identification is possible only by the genitalia structure: compared to those of N. melli sp. nov., the male genitalia of N. hortensis sp. nov. have the shorter apical costal lobe, the smaller and more weakly sclerotized carinal plate of the aedeagus with the much smaller thorn, and the significantly longer and broader medial diverticulum of the vesica with spines on its tip; compared to those of N. angkorensis , the male genitalia of N. hortensis sp. nov. have the valve narrower basally, the narrower distal section of the costa, the narrower apical costal lobe, the narrower ventral costal plate with the smaller ampulla, the larger distal membranous lobe of the valve, the significantly smaller aedeagus, the smaller and more weakly sclerotized carinal plate of the aedeagus with the much smaller thorn, the much narrower vesica, the much smaller distal diverticulum with the cluster of the smaller and less numerous spines, and the much shorter and narrower medial diverticulum with the much smaller spines on its tip. The female genitalia of N. hortensis sp. nov. differ from those of N. angkorensis in the significantly smaller antevaginal plate, the symmetric lateral margins of the ostium bursae, the longer ductus bursae, and the larger signum.

Distribution. The nominate subspecies is known from North Thailand (Chiang Mai and Nan provinces).

Etymology. ‘Hortensis’ means ‘garden’ in Latin, the species name refers to its type locality, the botanical garden in Doi Ang Khang (Chiang Mai Province of Thailand).
