(FIGS 4A, 5B, 6B, H, 7C)
Type locality: Jamaica, Blue Mountains National Park, 18°5′14.13″N 76°43′37.55″W, 1279 m.
Type material: Holotype: male (NMPC): Jamaica: Blue Mountain, 18°5′14.13″N 76°43′37.55″W, 1279 m, 14.xi.2013, F. Cala-Riquelme leg. ’. Paratypes: Jamaica: 19 spec. (CMN, MCZ, NMPC, NHMW) same data as holotype (including molecular voucher MF980); 2 spec. (BMNH): Newcastle, 19–22.viii.1908, M. Cameron lgt.
Description: Habitus as in Figure 5B. Body length 3.2–3.4 mm (holotype: 3.1 mm). Body oval, highly convex, elytral suture slightly elevated posteriorly. Dorsum dark brown to black, posterolateral corners of pronotum and apical part of lateral margins of elytra distinctly yellowish; ventral surface brown to reddish brown; femora and tibiae yellowish to reddish; antennae, maxillary palpi and tarsi yellowish. Head with sparse moderately coarse punctation, with mesh-like microsculpture; eyes small, separated by 6.9× dorsal width of one eye (Fig. 6B). Pronotum with sparse and fine punctures, smaller than on head, interstices with distinct mesh-like microsculpture. Elytral punctation sparse, moderately impressed, coarser than on head and pronotum; elytral interstices without microsculpture. Wings completely absent. Mesoventral elevation very narrow, as wide as metaventral process throughout, not narrowing anteriorly, without distinct anterior hood; metaventrite without deep pubescent pits at sides of metaventral process; metaventrite c. 5.1× wider than its length posterior of mesocoxae; median highly elevated portion narrow throughout (Fig. 7C). Aedeagus 0.6 mm long (Fig. 6H). Median lobe very narrowly triangular, c. 2.3× longer along midline than wide; apex slightly overlapping apices of parameres; gonopore small, subapical; lateral struts weakly expanded. Parameres sinuate on lateral margin, weakly expanded subapically, narrowly meeting each other basally. Phallobase as long as wide.
Etymology: This species is named in honour of Ondřej Jelínek, a good friend of the senior author, in appreciation of his friendship.
Diagnosis: Phaenonotum ondreji may be distinguished from other Caribbean species by the combination of small eyes, head and pronotum with distinct mesh-like microsculpture, and narrow highly elevated meso-metaventral keel. See Identification Key for additional diagnostic characters.
Distribution: Phaenonotum ondreji sp. nov. is only known from the eastern part of the island (Blue Mountains range, Fig. 4A).
