| Summary: | Lasionycta benjamini benjamini Hill Figs 43, 44, 156, 212. Map 9 Lascionycta [sic] benjamini Hill, 1927: 6. The nominate subspecies has an elongate oval orbicular spot and more prominently streaked appearance than L . b . medaminosa . It is also slightly larger and lighter in color. It occurs in California and Nevada. Lasionycta b . benjamini is unlikely to be confused with any other Lasionycta in its range. Lasionycta benjamini medaminosa Crabo & Lafontaine, ssp. n. urn:lsid:zoobank.org:act: 7785A5D8-FCA9-47FB-8A01-66F929793AA4 Figs 45, 46, 157, 213. Map 9 Type material. Holotype ♁.

CNC, LGC, TSDC. Etymology. Th e name is derived from the Greek medaminos meaning worthless. Diagnosis. Subspecies medaminosa occurs in Colorado. It is slightly smaller, less brown, and darker than L . b . benjamini and has a rounder orbicular spot and less streaky forewing. Lasionycta b . medaminosa resembles L . coloradensis with which it occurs. The subterminal line is less jagged in L . b . medaminosa than in L . coloradensis , and usually is preceded by a series of black chevrons, absent in L . coloradensis . The ventral hindwing discal spot and medial band of L . b . medaminosa are brown and less conspicuous than the black markings on L . coloradensis . Less streaky specimens of L . b . medaminosa are similar to L . subalpina , also found in Colorado. Lasionycta b . medaminosa has a well-defined hindwing marginal band and a bipectinate male antenna, whereas L . subalpina has lacks a marginal band and has a biserrate male antenna. Th e CO1 sequences of the L . benjamini subspecies differ by 1.05 %. Description. Head – Antenna of male bipectinate and fasciculate, individual segments 3.0–3.4× as wide as the central shaft. Antenna of female filiform and ciliate. Dorsal antenna segments dark gray proximally, light whitish gray ... |
