Brignolia dasysterna , new species Figures 95–141

Opopaea deserticola (misidentification): Platnick and Dupérre´, 2009: 4 (in part, females from southern Florida listed below only).

TYPES: Male holotype and female allotype taken in Berlese samples of young hammock forest litter at Deering Estate Park, SW 167th St. and SW 72nd Ave., S Miami, Dade Co., Florida (June 1–Aug. 25, 1986; J. and S. Peck), deposited in AMNH (PBI_OON 1270, 37534) .

ETYMOLOGY: The specific name is Latinized from the Greek adjective dasysternus (‘‘with shaggy breast’’), referring to the elaborately modified setae on the sternum of males.

DIAGNOSIS: Males can easily be recognized by the modified setae on the sternum (figs. 98, 115, 116), females by the long and curved (but untwisted) posterior genitalic tube (figs. 136–141)

MALE (PBI_OON 37533, figs. 95–118): Total length 1.58. Carapace pale orange, with dark brown egg-shaped patches behind eyes; pars cephalica slightly elevated in lateral view, posterolateral edge with pair of pits, posterior declivity without distinct shoulders, posterior margin round- ed. Sternum without pits but median portion of sternum coated with elaborately plumose setae originating from surface. Scuto-pedicel region with medially weak W-shaped scutal ridge, with low tubercles opposite pedicel triangles. Palpal tibia expanded ventrally at tip; embolus tip highly crenulated.

FEMALE (PBI_OON 1298, figs. 119– 141): Total length 1.67. Sternum without highly plumose setae. Posterior genitalic tube with transverse anterior portion, long, distally curved posterior portion.
