Key to the species of Leptostylopsis of Hispaniola

1 Dorsal surface of elytra and/or elytral epipleura with some iridescent green pubescence (sometimes only visible from certain viewing angles)................ 2

– Elytra without iridescent green pubescence................................................. 6

2(1) Iridescent green pubescence abundant and nearly uniform over most of dorsal surface ................................................................................................... 3

– Iridescent green pubescence limited to small patches .................................. 4

3(2) Prothorax with a distinct black macula on each side opposite base of elytral humerus; elytral epipleuron with large black macula at middle .................... ............................................................................................. L. viridicomus

– Prothorax without a black macula on side, opposite base of elytral humerus; elytral epipleuron with very small black macula at most............................... .................................................................................... L. chlorescens , sp. n.

4(2) Pronotum with very reduced, broadly rounded lateral tubercles; upper eye lobes much closer together than greatest width of scape; antennal scape without apical, dark, annula............................................ L. humerofulvus , sp. n.

– Pronotum with moderately to strongly projecting lateral tubercles; upper eye lobes as far or farther apart than greatest width of scape; antennal scape dark annulate at apex.......................................................................................... 5

5(4) Elytra with a distinct, transverse, undulating band of white pubescence at posterior 1/3, extending from suture to lateral edge; scutellum narrowly rounded posteriorly; pronotum without ochraceous pubescence ................... ......................................................................................... L. thomasi , sp. n.

– Elytra without an undulating, transverse band of white pubescence extending from suture to lateral edge; scutellum broadly rounded posteriorly; pronotum with abundant ochraceous pubescence........................................... L. milleri

6(1) Tarsomeres uniformly dark, not contrasting with apex of tibiae ..................7

– Most tarsomeres with white, off-white, or ochraceous pubescence at base at least, contrasting with apex of tibiae............................................................ 8

7(6) Antennae very long, extending beyond elytral apices by at least 4 antennomeres; pronotum without distinct black maculae; lateral pronotal tubercles very weakly projecting and broadly rounded.............. L. perfasciatus , sp. n.

– Antennae short, extending beyond elytral apices by less than 3 antennomeres; pronotum with numerous distinct, black maculae; lateral pronotal tubercles strongly projecting and abruptly rounded to subacute...................... L. poeyi

8(6) Pubescence on elytral tubercles suberect.................................................... 11

– Pubescence on elytral tubercles appressed.................................................... 9

9(8) Length greater than 13 mm; lower eye lobe very small, distinctly less than height of gena below it; prosternal process between procoxae less than 2/3 width of procoxa................................................... L. puntacanaensis , sp. n.

– Length less than 13 mm; lower eye lobe at least as tall as gena below it; prosternal process between procoxae at least 2/3 width of procoxa................... 10

10(9) Ochraceous pubescence covering much of elytral base and pronotum; pronotum without narrow, longitudinal, linear glabrous region at middle.............. ................................................................................................. L. annulipes

– Ochraceous pubescence absent from pronotum, restricted to small spots on elytron, at most; pronotum usually with a longitudinal, linear, glabrous line extending most of the way from anterior to posterior margins .................. L. argentatus

11(8) Tubercles at base of elytra forming a pronounced, highly elevated crest; pronotum with a narrow, longitudinal, black macula extending most of length at middle; females with terminal ventrite very long, 1.3 × broader than long; prolonged at middle into long ovipositor .................................... L. cristatus

– Tubercles at base of elytra elevated, but not strongly so; pronotum without elongate, black macula at middle of disk; females with terminal ventrite extended, not abruptly constricted, sometimes much more than 1.3 × broader than long .................................................................................................. 12

12(11) Base of elytra at sides of scutellum without white pubescent fasciae; pubescence on frons not appreciably distinct from that of gena; small, oval, black macula present on the epipleuron above the metepisternum; terminal ventrite of females about 1.3-1.4 × broader than long............... L. caliginosus , sp. n.

– Base of elytra at sides of scutellum with short, angled, white pubescent fasciae; pubescence on frons finer than and distinct from gena; small, oval, black macula usually absent on epipleuron above the metepisternum; terminal ventrite of females about 2.2 × broader than long............... L. basifulvus , sp. n.
