KEY TO THE CARIBBEAN PHAENONOTUM View in CoL

1. Eyes small, interocular distance 5.0–6.0× the width of one eye in dorsal view ( Fig. 6A–C). Metaventrite very short, its total width 5.0–6.0× the length behind mesocoxae ( Fig. 7A–C). Species without hind wings (apterous)....................................................................................................................................................... 2

– Eyes moderately large, interocular distance 3.5–4.0× the width of one eye in dorsal view ( Fig. 6D–F). Metaventrite moderately long, its total width 3.0–4.0× the length behind mesocoxae ( Fig. 7D–E). Species with fully developed hind wings (macropterous)..........................................................................................4

2. Metaventrite with pubescent cavities at sides of meso-metaventral process ( Fig. 7A). Elytral suture strongly elevated posteriorly; elytral punctation very coarse ( Fig. 5A). Pronotum with moderately coarse punctation, without microsculpture. Eastern Cuba ( Fig. 4). .................................. P. delgadoi Deler-Hernández et al., 2013 View in CoL .

– Metaventrite without pubescent cavities at sides of meso-metaventral process ( Fig. 7B–F). Elytral suture weakly elevated posteriorly; elytral punctation never extremely coarse. Pronotum either with distinct microsculpture or with extremely fine (nearly invisible) punctation..........................................................3

3. Body length 3.1–3.4 mm. Head and pronotum with mesh-like microsculpture and distinct punctation. Elytral punctation rather coarse, yellowish margins of elytra present in apical half only ( Fig. 5B). Mesoventral process moderately wide, median portion of metaventrite with narrow highly elevated median keel ( Fig. 7C). Aedeagus 0.6 mm long ( Fig. 6H). Jamaica ( Fig. 4). ................................................................. P. ondreji View in CoL sp. nov.

– Body length 2.5–2.7 mm. Head and pronotum without microsculpture, pronotal punctation extremely fine, almost invisible. Elytral punctation fine, whole lateral margins of elytra with yellowish stripe ( Fig. 5C). Mesoventral process very narrow, metaventrite with slightly elevated median portion, without median keel. Aedeagus 0.35 mm long ( Fig. 6I). Hispaniola ( Fig. 4). ............................................. P. laterale View in CoL sp. nov.

4. Median lobe of the aedeagus wide; gonopore large, situated in apical third of the median lobe. Bases of lateral struts of the median lobe weakly expanded laterally ( Fig. 6L). Widespread in the Greater Antilles ( Fig. 4). ......................................................................................... .. .................. P. laevicolle View in CoL complex
