Description: Habitus as in Figure 5D. Body size 3.2–3.3 mm (holotype: 3.3 mm). Body elongate oval, moderately convex, elytral suture not elevated. Dorsum black (dark brown in the teneral paratype), lateral margins of pronotum and elytra without distinct paler stripe; ventral surface dark brown to black; femora and tibiae black; antennae, maxillary palpi and tarsi yellowish. Head with sparse and moderately coarse punctation, without microsculpture (except posteriorly on frons); eyes moderately large, separated by 4.0× dorsal width of one eye ( Fig. 6D). Pronotum with sparse punctures slightly finer than on head, interstices without microsculpture. Elytral punctation strongly impressed, coarser than on pronotum and head; elytral interstices without microsculpture. Wings present, fully developed. Mesoventral elevation as wide as metaventral process posteriorly, narrowing anteriorly, with distinct anterior hood; metaventrite without pubescent pits on sides of metaventral process; metaventrite c. 4.0× wider than its length posterior of mesocoxae; median moderately elevated part of metaventrite narrow throughout ( Fig. 7D). Aedeagus 0.5 mm long ( Fig. 6J). Median lobe rather widely triangular, c. 1.8× longer along midline than wide; apex not reaching apices of parameres; gonopore moderately large, subapical; lateral struts projecting laterad. Parameres distinctly sinuate on lateral margin, slightly expanded subapically; widely meeting each other basally. Phallobase longer than wide.

Etymology: The species name is a Latinized adjective derived from the Spanish version of the indigenous Taíno name of the islands of Puerto Rico.

Diagnosis: Phaenonotum borinquenum may be distinguished from other Caribbean species by the combination of moderately large eyes, moderately long metaventrite, presence of wings and morphology of the aedeagus. It is extremely similar to P. exstriatum in its external morphology and genital morphology, and may be distinguished from it only by its smaller body size and widely meeting bases of parameres only. Despite the strong morphological similarity, it is not closely related to P. exstriatum .

D i s t r i b u t i o n: P h a e n o n o t u m b o r i n q u e n u m i s only known from the eastern part of Puerto Rico ( Fig. 4A).

Redescription: Habitus as in Figure 5A. Body length 2.2–2.5 mm (holotype: 2.3 mm). Body oval, strongly convex, elytral suture distinctly elevated posteriorly. Dorsum black, lateral margins of pronotum and elytra without distinct paler stripe; ventral surface brown to dark brown; femora and tibiae reddish; antennae, maxillary palpi and tarsi yellowish. Head with sparse fine punctation, without microsculpture (except posteriorly on frons); eyes small, separated by 5.2× dorsal width of one eye ( Fig. 6A). Pronotum with very sparse minute punctures much smaller than on head, interstices without microsculpture. Elytral punctation very strongly impressed, much coarser than on pronotum and head; elytral interstices without microsculpture. Wings completely absent. Mesoventral elevation as wide as metaventral process throughout, not narrowing anteriorly, with distinct anterior hood; metaventrite with a deep pubescent pit on each side of metaventral process; metaventrite c. 5.8× wider than its length posterior of mesocoxae; median moderately elevated part of metaventrite narrow anteriorly, widening posteriorly ( Fig. 7A). Aedeagus 0.4 mm long ( Fig. 6G). Median lobe rather narrowly triangular, c. 1.9× longer along midline than wide; apex not reaching apices of parameres; gonopore small, subapical; lateral struts simple, not expanded. Parameres indistinctly sinuate, nearly evenly arcuate on lateral margin, not expanded subapically, broadly meeting each other basally. Phallobase slightly wider than long.

Diagnosis: Phaenonotum delgadoi may be distinguished from all other Phaenonotum known to us by the combination of extremely coarse elytral punctation, elevated elytral suture and deep pubescent pits on each side of metaventral process. See Identification Key for additional characters.

Distribution: Phaenonotum delgadoi is only known from eastern Cuba, all known localities are situated in the Nipe-Sagua-Baracoa mountain system ( Fig. 4A).
