( Figs. 2–3View FIGURES 1 – 32, Map 3)

Identification. Forewing length 10.0–13.0 mm. Metalectra discalis  has a dark brown forewing mixed with creamcolored, gray, and reddish-brown scales. Basal and medial areas darker than rest of wing, but this may be less evident in worn specimens. Reniform spot is black and quadrate. Orbicular spot is black and obscure, not present in all specimens. There is a slightly curved row of white spots in the subterminal area. Hind wing has a similar pattern to forewing with a black, rectangular, discal spot; a curved line of small white spots; and a pair of white bars in the anal area. Similar to Metalectra quadrisignata (Walker)  , but M. discalis  is darker in overall appearance with a wider black medial area that is less distinct than in M. quadrisignata  .
