3831DA62D6F21DEAE26A703B5EB5F842.taxon	description	Description. Eyeless, unpigmented, longest male approximately 9.0 mm, female 9.4 mm. Body slender, linear, about 4.3 x as long as wide. Head about 1.4 x as wide as long, rostrum and lateral incisions absent. Coxae not visible in dorsal view. Body becoming more dorsally spinose on pereonites 6 - 7 and pleon. Pleotelson about 1.65 x as long as wide, caudomedial lobe moderately produced, broadly rounded. Antenna 1 of 20 articles, distal 6 articles each with one esthete, then alternate articles with one esthete (8 esthetes total). Antenna 2 broken or detached in most specimens, flagellum 57 - 58 merous, esthetes absent. Mandibles with 4 - cuspate incisors and lacinia; spine row with 5 spines on left, 4 spines on right, both with simple stout spines adjacent to incisors that resemble the cusps of the incisors and spines distad from incisors with complex plumosity; left molar with row of 15 plumose setae, right molar with row of 12 plumose setae. Mandibular palp 3 - merous, with plumose setae on distal articles. Maxilla 1, inner lobe with 4 apical stout plumose spines; outer lobe with 12 dentate apical spines. Maxilliped without retinaculae. Pereopods with sexual dimorphism not apparent. Pereopod 1, dactyl with elongate spine resembling accessory claw, 0.8 x length of claw; propodus about 2.1 x as long as wide, palmar margin with 4 - 6 robust plumose spines; carpus with 3 - 4 spines continuing from propodus. Pereopods 2 - 7 increasing in length, pereopod 7 longest; dactyls with prominent elongate claw-like spine parallel to claw. Male pleopod 1, protopod with retinaculae absent; exopod oval with 5 elongate disto-lateral setae. Female pleopod 2 triangular, about 2.1 x as long as wide, with 3 setae inside mesial margin, 1 distal seta and 1 lateral seta at mid-point. Male pleopod 2, protopod elongate, about 1.7 x as long as wide; exopod, proximal article sub-equal in length to distal article, setae absent, distal article broadly rounded apically, with 5 lateral setae; endopod, setation absent, distal article about 2 x length of proximal article, bent at approximately 60 degree angle to proximal article, tip bi-lobed, separated by endopodial groove terminating in sub-conical stylet (cannula). Pleopod 3, exopod with transverse suture, distal area slightly longer than proximal, with submarginal spines in row along mesial margin, spines and setae along distal and lateral margins; endopod about 0.6 x length of exopod, bifurcated distally. Pleopod 4, exopod with oblique suture, about 2.5 x as long as wide, area distal to suture about 0.67 x length of proximal area, with about 32 marginal setae; endopod about 0.6 x length of exopod, bifurcated distally. Pleopod 5, exopod with oblique suture, setae absent, about 2.5 x as long as wide, area distal to suture about 0.3 x length of proximal area; endopod sub-equal in length to exopod, bifurcated distally. Uropods about 2.4 mm in length, equal to pleotelson; rami slender, linear, endopod 5 x length of protopod, 1.25 x length of exopod.	en	Lewis, Julian J., Sawicki, Thomas R.

3831DA62D6F21DEAE26A703B5EB5F842.taxon	etymology	Etymology. Named for the state of Florida, in recognition of the first stenasellid discovered in the United States east of the Mississippi. Suggested vernacular name is the Florida cave isopod.	en	Lewis, Julian J., Sawicki, Thomas R.
