Key to the species of Hoplocheiloma View in CoL View at ENA

1. Wing distinctly spotted, transverse bands broken up so the wing appears mostly infuscated, with 7 widely separated, clear, circular patches ( Fig. 7 View FIGURES 6–10 ). Head with only one large seta (inner vertical), other setae reduced or absent ( Fig. 6 View FIGURES 6–10 ).............................................................................. H. hispaniola View in CoL new species. Dominican Republic.

- Wing with a broad discal band crossing middle ( Fig. 25 View FIGURES 22–26 ). Head with three large setae (inner vertical, orbital and outer vertical, as in Fig. 22 View FIGURES 22–26 )......................................................................................... 2

2. Notum mostly black, postpronotum contrastingly reddish. Base of oviscape bare and shining dorsomedially ( Fig. 21 View FIGURES 17–21 )...... 3

- Notum entirely orange to orange-brown, sometimes patterned with silvery grey areas. Pruinose area at base of oviscape surrounding oviscape so there is no dorsomedial shining strip ( Fig. 25 View FIGURES 22–26 ).............................................. 4

3. Wing mostly infuscated, with discal and preapical dark bands separated by clear strips each made up of three more or less coalesced clear circular areas, circular areas usually separated by pigmentation along the wing veins but both clear and dark bands always reaching hind wing margin; apical infuscation distinct ( Fig. 14 View FIGURES 13–16 ). Anterior notopleural seta at most half as long as posterior seta. Membranous parts of abdomen mostly pale, female abdomen with pleural pigmentation mostly restricted to bands on dorsal half ( Fig. 13 View FIGURES 13–16 ), male abdomen with pigmentation of segment three circling abdomen and preceded and followed by extensive pale areas........................................ H. maculosum (Loew) View in CoL . Dominican Republic, Cuba.

- Wing bands separated from one another by straight-sided clear strips; dark preapical band parallel-sided, broadly separated from hind margin of wing; apical infuscation indistinct ( Figs. 11, 12 View FIGURES 11–12 ). Notopleural setae equal in size. Abdominal membranes more extensively pigmented, ventral part of abdomen largely dark............................. H. jamaica View in CoL new species

4. Head and notum orange-brown, presutural part of scutum patterned with silvery grey areas. Wing with three distinct pigmented bands and an infuscated tip, outer margin of discal and preapical bands concave at middle ( Fig. 25 View FIGURES 22–26 ). Hind femur dark at least on basal half, with 1–2 orange distal bands.................. H. perforatum Cresson. View in CoL Dominican Republic, maybe Brazil.

- Head and notum orange, at least presutural part of scutum without silvery gray pattern. Hind femur usually orange with narrow dark bands (sometimes uniformly orange-brown). Outer margins of discal band convex or more or less straight, preapical band narrow and more or less straight-edged ( H. totliana View in CoL , Fig. 33 View FIGURES 31–35 ) or coalesced with apical infuscation to form a composite distal band ( H. ferrugatum View in CoL , Fig. 5 View FIGURES 5 )............................................................................. 5

5. Wing with discal band sometimes broad but never reaching hind margin of wing, distal band narrow but distinct from apical infuscation ( Fig. 27 View FIGURES 27–30 ). Epicephalon and paracephalon dull, paracephalon not conspicuously bulging. Main vertical row of katepisternal setae usually darker than weaker anterior golden row............................................... 6

- Discal band very large, taking up most of wing, broadly reaching hind margin of wing and separated from large apical infuscated area (distal band coalesced with apical infuscation, by a narrow transverse pale area ( Fig. 5 View FIGURES 5 ). Epicephalon and paracephalon shining, paracephalon conspicuously bulging ( Fig. 5 View FIGURES 5 ). Main vertical row of katepisternal setae golden, same color as weaker anterior golden row............................................. H. ferrugatum Hennig. View in CoL Mexico (Yucatan).

6. Pleuron with two prominent dark patches covered with silvery pruinosity, one covering the posterior third of the anepisternum and a less distinct one on the upper katepisternum ( Fig. 27 View FIGURES 27–30 ). Discal band more or less circular, widely separated from anterior wing margin and with distal face strongly convex. R 2+3 ending far beyond plane of dm-cu ( Figs. 1 View FIGURES 1–4 , 27 View FIGURES 27–30 ).................. 7

- Pleuron uniformly orange. Discal band with distal face almost straight, anterior part reaching wing margin ( Fig. 33 View FIGURES 31–35 ). R 2+3 ending at or very slightly beyond plane of dm-cu... H. totliana (Gmelin) View in CoL (widely known as H. fabricii Steyskal View in CoL ) USA (Florida), Puerto Rico, St. Thomas, Puerto Rico, Cuba, Jamaica, St. Martin (Widespread in Antilles but not known from Hispaniola).

7. Discal spot of wing small, less than half wing width and not approaching R 2+3 ( Fig. 4 View FIGURES 1–4 ). Base of arista usually brown................................................................................ H. dominica View in CoL new species. Dominica

- Discal spot of wing large, at least half wing width and touching or crossing R 2+3 ( Fig. 27 View FIGURES 27–30 ). Base of arista yellow................................................................................... H. rhytisma View in CoL new species. Montserrat
