Diagnosis. Janzena pyraliformis is easily distinguished from all other North American noctuoids by the scales beneath and posterior to the prothoracic collar that are greatly elongated to form a crest behind the head.

Description. Antennae filiform, ciliate; head, vertex, and abdomen brown; thorax white with scattered brown scales; brown prothoracic collar elongated to form a crest. Dorsal forewing (both sexes). Forewing length 9–10 mm. Ground color brown; basal area brown with small off-white spots; antemedial line a broad, off-white band extending diagonally from inner margin to costa above orbicular spot; broad, diffuse, off-white postmedial line is met at CuA2 by a similar broad, off-white band extending to orbicular spot, these off-white lines effectively divide the entire area of the forewing (basal to the postmedial line) into three distinct brown triangles: the first basal to the antemedial line, the second with the orbicular spot at the apex, and the third with the reniform spot at its center; undulating subterminal line a series of black dots; a second series of black dots is present in the subterminal area, terminal line a series of off-white specks between veins; fringe brown; orbicular spot off-white with light gray center and encircled with dark brown; reniform spot a rust brown lunule surrounded with dark brown. Dorsal hindwing. Light brown, gradually becoming darker toward outer margin; veins and discal lunule highlighted with darker brown scales; terminal line dark brown; fringe light ochre brown. Genitalia ( Fig. 66 View Figures 61–66 , 109 View Figures 105–113 ). As described in genus description (above).

Type material. Holotype male: USA: Florida, Monroe Co.: Long Point Key , 24.749°N, 80.984° W, 22.Feb.2015, J. Troubridge, in the CNC ( BOLD sample ID: CNCLEP 00116227). GoogleMaps

Etymology. The specific epithet refers to the habitus, which closely resembles that of a pyralid.

Distribution. This holotype is the only specimen to have been collected in Florida. Janzena pyraliformis is apparently common in Costa Rica (D. H. Janzen pers. comm.), and it also occurs in Puerto Rico.
