Apterous male holotype ( Figs. 1 View FIGURE 1 A–B, 1E). BL 4.43; HL 0.57; HW 0.70; ANT I 0.87, ANT II 0.70, ANT III lost, ANT IV lost; EYE 0.19; PL 1.32 ; PW 1.09 ; FORELEG: FEM 1.38, TIB 0.96, TAR I 0.09, TAR II 0.09, TAR III

0.28; MIDLEG: FEM 1.68, TIB 1.58, TAR I 0.09, TAR II 0.26, TAR III 0.36; HINDLEG: FEM 1.75, TIB 1.53, TAR I–III lost.

Head brown, with long brown setae on frons, adjacent to mesal eye margin, and posterolateral angles. Antenna light brown, apex of antennomere II darker. Eyes shining, dark red to blackish. Jugum without patch of silvery setae. Labium yellowish; distal portion of article III and entire IV brown. Pronotum yellow, lighter on posterior lobe, with brown spots laterally and medially on anterior lobe, and submedially on anterior portion of posterior lobe ( Fig. 1A View FIGURE 1 ); patches of silvery setae laterally on anterior lobe. Ventral surface of humeri yellow. Thoracic pleura brown; lateral surfaces of acetabula brownish. Patches of silvery setae on proepisternum and dorsally to lateral surfaces of acetabula ( Fig. 1E View FIGURE 1 ). Prosternum yellowish brown; meso- and metasterna dark brown. Ventral surfaces of acetabula yellow to brown. Coxae and trochanters yellow. Femora yellow on basal halves, then brown to dark brown with a preapical yellow band ( Figs. 1 View FIGURE 1 A–B). Tibiae brown to dark brown with a subbasal and a median yellow band ( Figs. 1 View FIGURE 1 A–B, 1E). Fore and middle tarsi mostly yellow, brown at apex. Abdominal mediotergites dark brown, darker on lateral margins. Laterotergites brown with yellow spots on anterolateral angles. Abdominal sterna dark brown to black with yellow to brown lateral margins; longitudinal stripe of silvery setae laterally on abdominal sterna II–III ( Fig. 1E View FIGURE 1 ).

Posterior margin of eye touching anterior margin of pronotum or distant from it by up to 30% of dorsal eye length ( Fig. 1A View FIGURE 1 ). Antennomere I thickest, curved laterally; II cylindrical; III–IV missing. Buccula lacking punctations. Labium reaching middle of mesosternum. Pronotum almost flat, distinctly constricted anterior to humeri; margins thickened on collar and posterior lobe; humeri not projecting; punctations small, deep, more numerous on posterior lobe ( Fig. 1A View FIGURE 1 ). Pro- and mesopleura each with a row of punctations; few punctations on lateral surface of metacetabulum. Metasternum with a pair (1+1) of inconspicuous tubercles laterally underneath middle coxae. Wings absent. Legs covered by decumbent setae. Inner surfaces of fore tibia, middle femur, and hind femur and tibia each with several black spinules. Hind femur slightly incrassate, about 1.5 times as wide as middle femur ( Fig. 1B View FIGURE 1 ). Hind tibia straight. Abdominal medio- and laterotergites covered by short shining setae, without long setae. Posterior margin of abdominal mediotergite VIII rounded, without central notch. Abdominal sternum VII with posterior margin widely concave and posterolateral angles weakly produced ( Fig. 1B View FIGURE 1 ). Paramere long, wider centrally, with rounded apex.

Discussion. Steinovelia permista differs from S. stagnalis and S. virgata by having the pronotum almost flat ( Fig. 1E View FIGURE 1 ), the humeri not projecting ( Figs. 1A, 1C View FIGURE 1 ), and the hind femur about 1.5 times as wide as the middle femur ( Figs. 1B, 1D View FIGURE 1 ), whereas in the other two species the pronotum is centrally elevated ( Figs. 2G View FIGURE 2 , 4G View FIGURE 4 , 5E View FIGURE 5 ), the humeri are usually projecting ( Figs. 2 View FIGURE 2 A–B, 4A–C, 5A, 5C), and the hind femur is about as wide as the middle femur ( Figs. 2D, 2F View FIGURE 2 , 4E View FIGURE 4 , 5B, 5D View FIGURE 5 ). Only the apterous form of S. permista is known, whereas S. vinnula is known from micropterous and macropterous forms. These two species also can be separated by the eyes located further from the anterior margin of pronotum ( Fig. 3A View FIGURE 3 ), the projecting humeri ( Fig. 3A View FIGURE 3 ), and the larger spines on the hind femur ( Fig. 3C View FIGURE 3 ) in S. vinnula .

Distribution ( Fig. 6 View FIGURE 6 ). Haiti ( Polhemus & Polhemus 1993); Puerto Rico ( Polhemus & Polhemus 1993); Trinidad & Tobago ( Drake 1951a).
