Allocapnia starki Kondratieff & Kirchner

Distribution. This species was known only from Mississippi and adjacent areas in Louisiana (Stark & Lacy 2005; Nations et al. 2007; Stark & Hicks 2009), until recently reported in the Cahaba River, Alabama ( Graves & Ward 2011). Our records are the first reported for Florida ( Fig. 1 ).

Material examined. FLORIDA: Calhoun Co., Jenkins Creek at CR 286, N 30°35’47”, W 84°59’28”, 20 January 2011, D. Ray, R. Abad, A. Rasmussen 12♂ (+ 1 larva ♂ reared), 12♀ (+ 2 larvae ♀ reared) . Same site, 6 December 2005, M. Pescador, B. Richard, 8 larvae . Same site, 10 February 2005, A. Rasmussen, B. Richard, 3 larvae. Johnson Creek at CR 286, N 30° 35’45.3”, W 84° 59’27.8”, 20 January 2011, D. Ray, R. Abad, 54♂, 25♀, 36 larvae, (+ 4♂ & 3♀ reared) . Same site, 6 December 2005, M. Pescador, B. Richard, 1 larva .

Remarks. Adult identifications were facilitated by using scanning electron microscopy ( Figs. 4-9 ). The “hybrid flocks of ancestral and derived forms” of A. recta ( Claassen 1924) designated by Ross & Ricker (1971) from sites along the Florida border in Escambia Co., Alabama, probably also represent A. starki . All larvae collected in January 2011 emerged between the 20 th and 25 th of January. The substrate for both Florida sites where Allocapnia larvae were found is gravel. Johnson Creek was gradually reduced to a series of isolated gravel substrate pools during the spring of 2011. Spring (April- June) in the Florida Panhandle is typically a dry season; this was exceptionally so during the first six months in 2011.
