Deler-Hernández 2016, isolate deposited at Department of Entomology, National Museum in Prague (green printed) ’ (Molecular voucher MF 1729). Description: Habitus as in Figure 5 D. 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. 6 D). 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. 7 D). Aedeagus 0.5 mm long (Fig. 6 J). 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.

(AS- 04 - 037) (molecular voucher MF 1738). Redescription: Habitus as in Figure 5 E. Body length 3.3 – 4.0 mm. Body elongate oval, moderately convex, elytral suture not elevated posteriorly. Dorsum black, lateral margins of elytra with very narrow indistinct paler stripe, pronotum paler in posterolateral corners; ventral surface dark brown to black; femora and tibiae black; antennae, maxillary palpi and tarsi yellowish. Head with sparse moderately coarse punctation, without microsculpture (except posteriorly on frons); eyes moderately large, separated by 4.0 × dorsal width of one eye (Fig. 6 E). Pronotum with sparse fine punctures, slightly smaller than on head, interstices without microsculpture. Elytral punctation moderately impressed, coarser than on pronotum and head; elytral interstices without microsculpture. Wings present, well developed. Mesoventral elevation as wide as metaventral process posteriorly, slightly narrowing anteriorly, with distinct anterior hood; metaventrite without pubescent pits on sides of metaventral process; metaventrite c. 3.9 × wider than its length posterior of mesocoxae; median moderately elevated part of metaventrite moderately wide throughout (Fig. 7 E). Aedeagus 0.4 mm long (Fig. 6 K). Median lobe narrowly triangular, c. 2.1 × longer along midline than wide; apex reaching apices of parameres; gonopore small, subapical; lateral struts expanded laterally. Parameres distinctly sinuate on lateral margin, slightly expanded subapically. Phallobase longer than wide. Diagnosis: Phaenonotum exstriatum may be distinguished from Caribbean species except P. borinquenum by the combination of moderately large eyes, moderately long metaventrite, presence of wings and morphology of the aedeagus. It may be distinguished from P. borinquenum by larger body size and bases of parameres meeting in single point only. Despite the strong morphological similarity, it is not closely related to P. borinquenum (see Fig. 2). Distribution: Phaenonotum exstriatum is widespread in the eastern USA and in Central America (Smetana, 1978; Deler-Hernández & Fikáček, 2016) as well as in Greater and Lesser Antilles (Fig. 4 B). The only record from South America is from eastern Colombia Gonzáles-Rodríguez, García-Hernández & Clarkson (2017). but the species is probably widespread in northern South America as it is common in southern islands of Lesser Antilles and it also occurs in Trinidad.	en	Deler-Hernández, Albert, Sýkora, Vít, Seidel, Matthias, Cala-Riquelme, Franklyn, Fikáček, Martin (2018): Multiple origins of the Phaenonotum beetles in the Greater Antilles (Coleoptera: Hydrophilidae): phylogeny, biogeography and systematics.

(VZ 10 - 0202 - 03 A) (molecular voucher MF 1740). Redescription: (refers to the Caribbean specimens examined): Habitus as in Figure 5 F. Body length 2.7 – 3.1 mm. Body elongate oval, moderately convex, elytral suture not elevated posteriorly. Dorsum black, lateral margins of elytra with paler stripe reaching subapically, pronotum paler in posterolateral corners; ventral brown to dark brown; femora dark brown to reddish, tibiae reddish; antennae, maxillary palpi and tarsi yellowish. Head with sparse fine punctation, without microsculpture (except posteriorly on frons); eyes moderately large, separated by 3.6 × dorsal width of one eye (Fig. 6 F). Pronotum with sparse fine punctures similar to that on head, interstices without microsculpture. Elytral punctation moderately impressed, coarser than on pronotum and head; elytral interstices without microsculpture. Wings present, well developed. Mesoventral elevation slightly narrower than metaventral process posteriorly, slightly narrowing anteriorly, with distinct anterior hood; metaventrite without pubescent pits on sides of metaventral process; metaventrite c. 3.5 × wider than its length posterior of mesocoxae; median moderately elevated part of metaventrite moderately wide throughout (Fig. 7 F). Aedeagus 0.5 mm long (Fig. 6 L). Median lobe rather triangular, c. 1.7 × longer along midline than wide; apex reaching apices of parameres; gonopore large, wide, situated in apical third of median lobe; lateral struts very shortly expanded laterally. Parameres distinctly sinuate on lateral margin, strongly expanded subapically, broadly meeting each other basally. Phallobase longer than wide. Comments: Both sequenced specimens (MF 1115 from Cuba and MF 1740 from Venezuela) form a strongly supported clade in the molecular analysis and are evidently closely related (pairwise distance of cox 1 sequences is 4.8 %). Both specimens correspond with each other in external morphology and the characteristic shape of male genitalia, and only differ in body size: the Cuban specimen is smaller (2.8 mm), the Venezuelan specimen larger (3.4 mm). In this aspect, the sequenced Cuban specimen corresponds to all additional Greater Antillean specimens examined, which are also rather small (2.7 – 3.1 mm). Hence, it seems probable that Venezuelan specimen is not conspecific with the Greater Antillean ones, but additional material is necessary to evaluate the intraspecific genetic and morphological variability properly to decide whether the sequenced specimens represent one or two species. The external morphology, body size and the morphology of genitalia of the Caribbean specimens correspond to the types of P. laevicolle Sharp, 1882 described from Guatemala and examined by Deler-Hernández & Fikáček (2016). However, due to the absence of DNAgrade specimens of P. laevicolle from Central America, we are unable to determine whether the Greater Antillean specimens are conspecific. For that reason, we consider all above specimens as members of the Phaenonotum laevicolle species complex whose taxonomy needs to be addressed once more material will be available. Distribution: The Caribbean specimens of the Phaenonotum laevicolle complex are known from central and eastern Cuba and western Hispaniola (Haiti). Outside the Caribbean, the species complex clearly occurs in southernmost Northern and Central Americas (types of P. laevicolle) and in northern South America [as P. globulosum (Mulsant, 1844) from Colombia (Hansen, 1999; not examined by us) and the Venezuelan specimen sequenced by us]. The records from Argentina (types of P. spegazziinii Bruch, 1915 not examined by us) seem doubtful (Oliva et al., 2002) and are not considered here. Based on these sources, we estimate the distribution of the species complex to be as shown in Figure 4 C.	en	Deler-Hernández, Albert, Sýkora, Vít, Seidel, Matthias, Cala-Riquelme, Franklyn, Fikáček, Martin (2018): Multiple origins of the Phaenonotum beetles in the Greater Antilles (Coleoptera: Hydrophilidae): phylogeny, biogeography and systematics.

Dorsum brown to dark brown, lateral margins of pronotum and lateral and sutural margins of elytra with distinct yellowish stripe; ventral surface brown to reddish 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 5.1 × dorsal width of one eye (Fig. 6 C). Pronotum with very sparse and very fine punctures much smaller than on head, interstices with not very distinct mesh-like microsculpture. Elytral punctation sparse and moderately impressed, similar to that on head, much coarser than on pronotum; elytral interstices without microsculpture. Wings completely absent. Mesoventral elevation extremely 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. 5.0 × wider than its length posterior of mesocoxae; median weakly elevated part of metaventrite narrow throughout (Fig. 7 B). Aedeagus 0.35 mm long (Fig. 6 I).

Parameres indistinctly sinuate on lateral margin, not expanded subapically, widely meeting each other basally. Phallobase as long as wide. Etymology: The species name refers to the conspicuous yellow stripe along lateral margins of pronotum and elytra characteristic of this species. Diagnosis: Phaenonotum laterale may be distinguished from other Caribbean species, based on its brown-yellow coloration, obsolete pronotal punctation and extremely narrow meso-metaventral keel. See Identification Key for further diagnostic characters. Distribution: Phaenonotum laterale sp. nov. is only known from a high altitude cloud forest region in the southwestern Dominican Republic, geologically situated on the southern paleoisland of Hispaniola (Fig. 4 A).	en	Deler-Hernández, Albert, Sýkora, Vít, Seidel, Matthias, Cala-Riquelme, Franklyn, Fikáček, Martin (2018): Multiple origins of the Phaenonotum beetles in the Greater Antilles (Coleoptera: Hydrophilidae): phylogeny, biogeography and systematics.

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. 7 C). Aedeagus 0.6 mm long (Fig. 6 H). 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. 4 A).	en	Deler-Hernández, Albert, Sýkora, Vít, Seidel, Matthias, Cala-Riquelme, Franklyn, Fikáček, Martin (2018): Multiple origins of the Phaenonotum beetles in the Greater Antilles (Coleoptera: Hydrophilidae): phylogeny, biogeography and systematics.
