Key to the species of Antillipeltis

1. Elytra primarily yellow with dark brown or black maculae; vestiture of densely distributed, moderately long, fine, inclined or suberect setae ( Figs 1 B, 1F); pronotal punctures shallow with gradually sloping sides, appearing coarse and dense under oblique light source; pronotal interspaces very finely granulate and moderately shiny; length 4.0– 5.5 mm; Dominican Republic.................................................................................................... 2

- Elytra usually dark brown or black, sometimes with yellow pigment along suture or sides ( Figs 1 A, 1C–E); if main portion of elytral disc partly yellow, dark maculae absent and length less than 4 mm; vestiture of sparsely distributed, moderately long, erect fine setae or very short, fine setae, usually not extending beyond edges of punctures............................ 3

2. Head primarily yellow with large black area occupying vertex and part of frons; pronotum yellow with large triangular macula widest anteriorly and narrowing posteriorly ( Fig. 1 B); pronotum more than 0.6 times as long as wide with strongly curved sides; elytra about 3 times as long as pronotum; elytral punctation finer and sparser, and setae shorter..... A. maculata sp. n.

- Head dark brown or black; pronotum uniformly reddish-brown ( Fig. 1 F); pronotum about 0.5 times as long as wide with somewhat angulate sides; elytra more than 4 times as long as pronotum; elytral punctation coarser and denser and setae longer......................................................................................... A. pubescens sp. n.

3. Head, pronotum and ventral surfaces yellow; vestiture consisting of sparsely distributed, moderately long, erect, fine setae; elytra more than 1.6 times as long as wide; Miocene specimens in Dominican amber................................ 4

- Head and pronotum reddish-brown to black; vestiture consisting of minute setae usually not extending beyond edges of punctures; elytra less than 1.6 times as long as wide; extant species.................................................. 5

4. Pronotum more than 0.65 times as long as wide, its sides distinctly explanate with distinctly, coarsely crenulate edges; pronotal punctures unevenly distributed but usually separated by one or two diameters; length 3 mm ................. A. iviei sp. n.

- Pronotum less than 0.65 times as long as wide, its sides slightly explanate with weakly crenulate edges; pronotal punctures usually separated by more than two diameters; 2.7 mm ............................................. A. alleni sp. n.

5. Pronotal punctures with gradually sloping sides, appearing coarse and dense under oblique light source; pronotal interspaces very finely granulate or smooth and shiny; length less than 4 mm ................................................ 6

- Pronotal punctures with steep, abrupt sides, appearing fine and sparse under oblique light source; pronotal interspaces distinctly granulate with a dull sheen; length greater than 4 mm ................................................... 7

6. Length less than 3 mm; elytra yellow; pronotum reddish-brown; with sides only weakly rounded ( Fig. 1 C); Dominican Republic...................................................................................... A. minuta sp. n.

- Length greater than 3 mm; elytra dark brown with sides and suture yellow; pronotum black and somewhat metallic with sides distinctly rounded ( Fig. 1 D); Puerto Rico........................................................ A. nitida sp. n.

7. Head and pronotum black; pronotum with sides strongly rounded, somewhat angulate at middle and explanate with finely crenulate edges; elytra dark brown with yellow along sides ( Fig. 1 A); length more than 5 mm; Haiti..... A. darlingtoni sp. n.

- Head black; pronotum reddish-brown with sides weakly rounded, not explanate with coarsely crenulate edges; elytra dark brown with yellow along suture and sides ( Fig. 1 E); length less than 5 mm; Puerto Rico............ A. portoricensis sp. n.
