description: Key to the species of Hoplocheiloma   
 1. Wing distinctly spotted, transverse bands broken up so the wing appears mostly infuscated, with 7 widely separated, clear, circular patches (Fig. 7). Head with only one large seta (inner vertical), other setae reduced or absent (Fig. 6).............................................................................. H. hispaniola new species. Dominican Republic.   
- Wing with a broad discal band crossing middle (Fig. 25). Head with three large setae (inner vertical, orbital and outer vertical, as in Fig. 22)......................................................................................... 2  
2. Notum mostly black, postpronotum contrastingly reddish. Base of oviscape bare and shining dorsomedially (Fig. 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).............................................. 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). 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), male abdomen with pigmentation of segment three circling abdomen and preceded and followed by extensive pale areas........................................ H. maculosum (Loew). 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). Notopleural setae equal in size. Abdominal membranes more extensively pigmented, ventral part of abdomen largely dark............................. H. jamaica 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). Hind femur dark at least on basal half, with 1–2 orange distal bands.................. H. perforatum Cresson. 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, Fig. 33) or coalesced with apical infuscation to form a composite distal band (H. ferrugatum, Fig. 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). 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). Epicephalon and paracephalon shining, paracephalon conspicuously bulging (Fig. 5). Main vertical row of katepisternal setae golden, same color as weaker anterior golden row............................................. H. ferrugatum Hennig. 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). 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, 27).................. 7   
 - Pleuron uniformly orange. Discal band with distal face almost straight, anterior part reaching wing margin (Fig. 33). R 2+3 ending at or very slightly beyond plane of dm-cu... H. totliana (Gmelin) (widely known as H. fabricii Steyskal) 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). Base of arista usually brown................................................................................ H. dominica new species. Dominica   
 - Discal spot of wing large, at least half wing width and touching or crossing R 2+3 (Fig. 27). Base of arista yellow................................................................................... H. rhytisma new species. Montserrat
