Explanation of Names
Conchylodes octonalis (Zeller, 1873) was transfered from the genus Lygropia in Mally et al. (2019: 168).
octonalis: the "octo" probably refers to the 8 short bars on the forewings, and is the origin of the suggested common name Eight-barred Conchylodes, formerly Eight-barred Lygropia.
forewing length 7.5-8.5 mm(1)
Adult: forewing white to pale yellow with four brownish-orange bars along costa; bars connect via fine wavy lines to small markings along inner margin; upper half of fringe dark-scaled, lower half pale-scaled; hindwing white; legs white with thick brown bands; top of head and body white, with orange markings on thorax and abdomen
