Measurements and ratios (minimum-maximun, mean), in mm (n= 10): HL 0.2–0.3, 0.3; HW 0.7–0.8, 0.7; DBE 0.3–0.4, 0.3; PL 0.4–0.5, 0.5; PW 1.1–1.3, 1.2; PW/PL 0.3–0.4, 0.4; EL 1.3–1.4, 1.3; EW 1.2–1.4, 1.3; TL/EW 1.5–1.8, 1.6; TL 2.0– 2.2, 2.1. Diagnosis. Adults of D. andreae can be readily distinguished from other species of the genus by the aedeagus, with the median lobe having an unsclerotized and acute apically (Fig. 1 b); and parameres without a preapical, articulated process and the apex narrowing evenly (Fig. 1 d). Etymology. The new species is dedicated to Andrea Megna Alicio, mother of the first author, for her love. The species name is a noun in the genitive case. Distribution. D. andreae has been recorded from localities in mountainous areas of the Sierra Maestra (Oriental region) and Guamuhaya (Central region) (Fig. 6 a). Ecology. According to Miller (2005) species of Desmopachri a can occupy a wide variety of habitats including ponds, streams, forest pools and phytotelmata. Specimens of D. andreae were collected in the backwaters of freshwaters with clear water and muddy-stony bottoms, located in highlands with little exposure to sun, with abundant cover vegetation but without aquatic vegetation (Fig. 7). Species distribution modelling. The predictive map for D. anderae shows a high suitability (red areas in Fig. 9) in a few areas of the Sierra Maestra (S-SW of Cuba), while other suitable areas are distributed in the south of the island, mainly in the mountainous areas and also in the Macizo de Guamuhaya (central part of Cuba).

TL 4.0– 4.5 mm; EW 1.9–2.3 mm; see Table 1 for remaining body measurements. Color. Dorsal surface yellow to testaceous. Elytra with broad basal diffuse band extended to lateral margins in some specimens (Fig. 3); venter yellowish. Sculpture and punctation. Elytron with a submarginal and 10 discal striae (Fig. 3). First three abdominal ventrites with short curved strioles. Structure. Prosternum rounded medially, with anterior margin sinuate; prosternal process short, oval, finely margined laterally, bluntly pointed apically, flattened apically and broadly contacting anteromedial metaventral process; rounded lobes of metacoxal processes covering base of trochanters. Male protibia with two ventrobasal emarginations; metatibial spurs acute apically; metatarsomeres 1 to 4 flattened ventrally; metatarsal claws equal. Male genitalia. Median lobe with outside margin abruptly expanded in middle part (Figs. 21a, b); parameres broad, inner margin with short setae over apical half (Fig.21c). Sexual dimorphism. Males with pro- and mesotarsomeres 1–3 widened, with sucker-like setae. Protibia with two ventrobasal emarginations. Female protibia without ventrobasal emargination. Diagnosis. Adults of C. cordovai sp. nov. are recognized by the combination of the following characters: elytron with a posterolateral submarginal stria and 10 discal striae (Fig. 3); male protibia with two ventrobasal emarginations; median lobe with abrupt widening in middle part (Figs. 21a,b); parameres with short setae on inner margin (Fig. 21c). Copelatus cordovai sp. nov. can be confused with the Nearctic species C. glyphicus (Say, 1823) due to the similar pattern of 10 discal striae, but can be separated from it by the thicker median lobe (the median lobe of C. glyphicus is slender and strongly curved to the side apically). Etymology. The specific epithet cordovai is a noun in the genitive case which honors Yunier Córdova Cóbas (Barcelona, España) for his contribution and help to the senior author’s studies on aquatic coleopterans. Ecology. Copelatus cordovai sp. nov. was collected in lentic (permanent and temporary) habitats with abundant aquatic vegetation, muddy bottom and high water temperatures, from lowlands up to 50 m a.s.l. (Fig. 34) Distribution. In Cuba, Copelatus cordovai sp. nov. is recorded from both western (Isla de la Juventud) and eastern parts of the country (Las Tunas and Granma provinces) (Fig. 27).Published as part of Megna, Yoandri S. & Epler, John H., 2012, A review of Copelatus from Cuba, with the description of two new species (Coleoptera: Dytiscidae: Copelatinae), pp. 383-410 in Acta Entomologica Musei Nationalis Pragae 52 (2) on pages 391-392, DOI: 10.5281/zenodo.533101

Laccophilus alariei Megna, Deler-Hernandez, and Challet, new species
No full text<i>Laccophilus alariei</i> Megna, Deler-Hernández, and Challet, new species <p>(Figs. 1, 7, 13)</p> <p> <b>Holotype.</b> Male. <b>CUBA</b>, Guanahacabibes: El Verraco (21°55´08´´N 84°37´20´´W) 1 m, Pinar del Río Province, Cuba. 23-VII-2003 collected by Y. S. Megna and O. Bello (CZCTR).</p> <p> <b>Paratypes.</b> 2 males. Same date as the holotype. Other material examined: Total 2 specimens: Cuba, Isla de la Juventud, Punta del Este. 22-V-2006, collected by Y. S. Megna (CZCTR).</p> <p> <b>Diagnosis.</b> <i>Laccophilus alariei</i> is the largest species of the genus in the Antilles and North America (SBL= 8.13–8.56 mm), followed by <i>Laccophilus maculosus</i> Say (4.6–6.4 mm) (Larson <i>et al</i>. 2000), <i>Laccophilus sonorensis</i> Zimmerman (5.0–6.0 mm), and <i>Laccophilus quadrilineatus</i> Horn (5.0– 6.7 mm) (Zimmerman 1970). It has a color pattern similar to that of <i>L. quadrilineatus quadrilineatus</i> and <i>Laccophilus mistecus mistecus</i> Sharp from Mexico, but can be distinguished from those species by the following combination of characters: aedeagus strongly emarginate medially in ventral view (Fig. 7B); parameres with numerous setae near apex (Fig. 7D, E); last abdominal segment of male truncate; elytra without irrorations (Fig. 1). <i>Laccophilus alariei</i> belongs to the group of species that lack a metacoxal file and a rake-like ovipositor (Fig. 7G).</p> <p> <b>Description.</b> SBL= 8.13–8.56 mm; EW= 4.00– 4.14 mm; SBL/EW= 1.99–2.07 mm (Table 2). Dorsal surface of body brown to testaceous; head testaceous, with rufous marking posteriorly (Fig. 1); pronotum testaceous; elytra brown with testaceous maculations, yellow lateral stripes present, interrupted at midline with subbasal and medial extensions toward elytral disc, posterior stripes covering apical margin. Base of elytron with 3 longitudinal spots, one extending along elytral suture approximately to middle, and 5 small spots in a transverse row in posterior half (Fig. 1). Ventral surface rufous; antenna, mouthparts, fore- and midlegs testaceous. Prosternal process short. Aedeagus with apex curved; strongly emarginate in middle part in ventral view (Fig. 7B). Parameres with numerous setae apically (Figs. 7D, E). Oval plate as in Fig. 7F. Ovipositor rake-like (Fig. 7G).</p> <p> <b>Sexual Dimorphism.</b> Males do not have a metacoxal file and pro- and mesotarsomeres 1–3 are slightly widened, with sucker-like setae. The last abdominal segment is truncate with a sinuate apex in males, whereas it is produced in females.</p> <p> <b>Variation.</b> The basal elytral spots can be united to form an uninterrupted, irregular, and subbasal band. They can also be obsolescent so that the only visible spot is the one extended along the elytral suture. One specimen has a weakly colored longitudinal spot extending along the elytral suture. The small, irregularly arranged spots in the posterior half vary in form and can number from two to five.</p> <p> <b>Distribution.</b> <i>Laccophilus alariei</i> is recorded only from the western part of Cuba (Pinar del Río and Isla de la Juventud) (Fig. 13).</p> <p> <b>Etymology.</b> The specific epithet is a patronym honoring Dr. Yves Alarie (Laurentian University) for his broad contributions to the study of aquatic Coleoptera.</p> <p> <b>Ecology.</b> <i>Laccophilus alariei</i> has been collected in two coastal wetlands with abundant aquatic vegetation and muddy to stony sediments. Both localities are in a semideciduous forest habitat with sublittoral limestonel, which occurs in southern Cuba in three coastal areas: La Península de Guanahacabibes, Isla de la Juventud, and Ciénaga de Zapata (Matanzas province) (Arces 1978). This suggests a relationship between the distribution of <i>L. alariei</i> and soil type.</p>Published as part of <i>Megna, Yoandri S., Deler-Hernández, Albert & Challet, Gilbert L., 2011, Description Of A New Species Of Laccophilus Leach (Coleoptera: Dytiscidae), With Notes On Other Cuban Species, pp. 213-226 in The Coleopterists Bulletin 65 (3)</i> on page 218, DOI: 10.1649/072.065.0302, <a href="http://zenodo.org/record/10085379">http://zenodo.org/record/10085379</a>
