Diagnosis. Pogospinia floridana ( Fig. 8 ) is a small (forewing length 4.0‒5.0 mm) cream-colored moth with brown and dark brown markings. It is distinguished from its congeners by the shape of the median process of the transtilla ( Fig. 26 ), which is about as long as the free terminal lobes of the valva, and is emarginate distally with a tiny, short thorn on each terminal lobe. In comparison, the median process of the transtilla of P. spinifera is short and blunt. The width of the dorsal (costal) lobe of the valva of P. floridana is ca. equal to the width of ventral lobe. In comparison, the dorsal (costal) lobe of the valva of P. veracruzanus is ca. 1.5 times as wide as the width of ventral lobe.

Description. Head: Frons and vertex cream; labial palpus cream, mixed with tawny orange on outer surface, scaling only slightly expanded distally on segment II, second III slightly exposed; antenna with cream scales. Thorax: Nota mostly cream, slightly tawny; forewing length 4.0– 4.5 mm (mean = 4.3 mm, n = 5) in male, 4.5 mm (n = 2) in female; forewing ground color cream with scattered, ill-defined blotches of pale tawny; a blackish brown, triangular patch from lower edge at ca. 0.4 distance from base to apex, a small, ill-defined, brown costal blotch at ca. 0.2 distance from base to apex, a similar but larger blotch near mid-costa, and a similar colored fascia overscaled with pale tanwy at ca. 0.8 distance from base to apex, extending toward, but ending before tornus. Fringe cream. Hindwing white with pale beige overscaling. Fringe concolorous with hindwing. Abdomen: Mostly cream above and below. Male genitalia ( Fig. 26 ) essentially as described for genus; median process of transtilla about as long as lobes of valva, somewhat chordate-emarginate distally, with a tiny spine on each terminal lobe; valva widest at base, birfurcate in distal 0.33 creating a broad, U-shaped concavity along outer margin of valva; both arms of bifurcation nearly parallel-sided, dorsal arm with field of strong, conspicuously socketed setae restricted to arm, ventral arm with field of strong spines extending length of sacculus; vinculum arms forming narrowly rounded, V-shaped saccus. Phallus large, slender, 6–7 times as long as wide, attenuate-pointed apically; vesica without cornuti. Female genitalia ( Fig. 40 ) with papillae anales weakly lobate, setose; sterigma complicated with dense patches of spiculation, and V-shaped median region rounded at anterior margin; ductus bursae short, undifferentiated from corpus bursae; corpus bursae round, with patch of minute spicules on left side and truncate-cone-shaped process of long spines on right side.

Pogospinia floridana is known from the panhandle of northern Florida to the Keys at the southern tip of Florida (Escambia, Highlands, Collier, and Monroe counties). Collection records extend throughout the year, with the majority from October to March. Larvae collected on 14 April from Anthernanthera maritima (Amaranthaceae) at Long Key State Park in southern Florida produced adults that emerged on 29 April (n = 2) and 4 May (n = 1) of the same year.
