Diagnosis. Externally quite different by colour from other Belciana species, although habitus of hindwings matches well to Belciana spp. B. jeremyi sp. nov. is externally darker than other species, without green or light grey colours (Figures 1a, 2a), closest to B. pinratanai and B. hemodi (Behounek et al., 2015, figs 24–26 and 21–22). In the male genitalia, it resembles B. hemodi and B. pinratanai but differs from B. pinratanai by having more even valvae, a longer, thinner, narrower and evenly bent harpe, and more cornuti on vesica (Figure 1b, c) (Behounek et al. 2015, fig. 40); and differs from B. hemodi by having more narrower valvae, a thinner, narrower and evenly bent harpe (Figure 1b) (Behounek et al. 2015, fig. 39). Uncus similar to B. bicolour Wileman & West, 1929 but thinner (Behounek et al. 2015, fig. 38), terminated by small spine (Figure 1b).
Description. Head: Frons and vertex grey, palpi narrow slightly upturned, third segment in females three times longer than in males (Figure 3a, b). Antennae ciliate in males and females. Thorax and forewing dark brownish grey, patagia blackish-brown. Ground colour of forewing pale brownish grey, wing pattern presented by blackish-brown and light grey elements. Small basal dot, subbasal field half-filled with light brownish grey; antemedial line dark partly double, distinct, orbicular stigma unclear, reniform as black vertical streak; medial mark in costal area very large; postmedial and subterminal lines black, close to each other, postmedial one with sharp twist anally, submarginal line white with zigzag downwards; subapical-apical mark blackish apical dash; marginal line as a row of interrupted white streaks; termen with black spots, cilia light brown. Wingspan in males 31–34 mm and females 31–38 mm (Figures 1a, 2a). The hindwing dull greyish-brown around terminal margin, forming distinct terminal band, pale light brownish-grey towards the base and along anal margin, with diffused medial line and discal spot. Underside forewing brow grey, hindwing alike upperside, medial spot and line more clear, same as discal line. Abdomen: male genitalia (Figure 1b–d) Uncus slender, curved at a right angle in apical third, apically bending, narrow; tegumen narrow; juxta shield-like, narrower apically; valva narrow somewhat constricted apically, the base of sacculus membranous, without any coremata or hairs; Harpe bent, gradually narrowing, apically sharp, situated basally on sacculus; Aedeagus narrow, carina as two bands; with globular vesica bearing basally about dozen small spikes and apically five spikes. Female genitalia (Figure 2b) Ovipositor quadrangular; apophyses anteriores and posteriors ones moderate and equal in length; antrum rounded, not elongated, with split antevaginal plate; ductus bursae very short, strongly membranous in joining with narrow corpus bursae.
Etymology. The species is named after Jeremy Holloway in recognition of his work on the taxonomy and systematics of the Noctuoidea.
Distribution and bionomics. So far found in Northern Thailand Lampang Province. Foodplants and preimaginal stages unknown.
