......................... Elateropsis trimarginatus

(Cazier and Lacey) 19′. Pronotum without dense patch of white

pubescence adjacent to base of scutellum; legs (at least femora) and antennae ferruginous ( Fig. 3d )............................................... ........... Elateropsis sericeiventris Chevrolat

20. Elytra mostly smooth with sparse, shallow punctures; females with densely pubescent vittae on elytra (not confirmed for Hispaniola) ( Fig. 3b ) .................. Elateropsis lineatus (L.)

20′. Elytra with mostly rough surface with dense punctures; never with densely pubescent patches or vittae on elytra (as in Fig. 3c ) ............................................................ 21

21. Scutellum acute posteriorly, triangular; punctation of elytra mostly uniform in size and density from base to apex ( Fig. 2h, i )...... 22

21′. Scutellum as broad or broader than long, subreniform or rounded posteriorly; punctation of elytra larger or semirugose basally, becoming shallower, smaller, and denser apically (as in Figs. 2e , 4a, b, g, h )........26

22. Pronotum with densely pubescent patches

(either at sides, posterior margin, or both); with or without an anteromedial depression..................................................................23

22′. Pronotum without densely pubescent patches; with an anteromedial depression................... ...................... Elateropsis femoratus (Sallé)

23. Pronotum with punctures concentrated primarily in posterior half, mostly smooth and glabrous anteromedially ( Fig. 2h ); disc of pronotum flattened ......................................... .................... Elateropsis antennatus Galileo

and Martins 23′. Pronotum with punctures more evenly scat-

tered throughout, not mostly smooth anteromedially ( Fig. 3d, g ); disc of pronotum convex, evenly rounded...........................24

24. Pronotum with dense pubescence along posterior margin; integument color uniformly black ( Fig. 3c ).............................................. ...... Elateropsis quinquenotatus Chevrolat

24′. Pronotum without dense pubescence along posterior margin; integument color variable (as in Fig. 2h )..........................................25

25. Integument completely piceous-black in dorsal view ( Fig. 3g ) ................................... ................ Elateropsis woodleyi Lingafelter

25′. Integument (usually femora, antennae, and part of elytra) partially ferruginous in dorsal view ( Fig. 3d ) ..... Elateropsis sericeiventris Chevrolat

26. Pronotum with lateral margins with small, antemedial spine and larger, postmedial spine, without crenulae or dentition between them; elytral base distinctly rugose; legs uniformly black or piceous (not confirmed for Hispaniola) ( Fig. 2e ) ............................. ........... Derancistrus anthracinus (Gahan)

26′. Pronotum with lateral margins with combination of spines, denticles, and crenulae; legs (at least femora) reddish-brown or orange ( Fig. 4a, b, g, h )......................................... 27

27. Legs distinctly bicolored with most of femora orange and tibiae dark reddish brown to black ( Fig. 2g, h ). Prosternal process moderately bilobed with apices slightly divergent ( Fig. 6b, e ).................................................. 28

27′. Legs unicolorous, without distinct difference in color of tibiae and femora ( Fig. 5a–f ). Prosternal process strongly bilobed with apices greatly divergent ( Fig. 5b, e ).............. .................................... Solenoptera furfurosa (Galileo and Martins)

28. Pronotal margin evenly dentate, without anterolateral lobe or posterolateral spine ( Figs. 4g , 6a ). Elytral epipleural lateral margin nearly completely visible in dorsal view. Elytral base coarsely punctate, with small, bead-like, explanate margin at base of humerus on anterolateral corner ............ .................. Solenoptera helbi Lingafelter

28′. Pronotal margin unevenly dentate, with anterolateral lobe and posterolateral spine ( Figs. 4h , 6d ). Elytral epipleural lateral margin incomplete and mostly obscured in dorsal view. Elytral base rugosely punctate, without bead-like, explanate margin at base of humerus on anterolateral corner ............... ................... Solenoptera rugosa Lingafelter
