Taxonomic Notes. After examination of the Marcuzzi and Zayas types, it was determined that Cnodalon trinitatis Zayas is a synonym of Cyrtosoma (Nesocyrtosoma) inflatum Marcuzzi New Synonymy. Marcuzzi, having already described Cyrtosoma trinitatis s. s. (1976), gave Zayas’ Cnodalon trinitatis the replacement name Cyrtosoma iviei Marcuzzi 1998 , but with the new synonymy, the replacement name is now unnecessary. Garrido and Gutiérrez (1996) incorrectly synonymized Cnodalon inflatum Zayas with Cyrtosoma (Nesocyrtosoma) inflatum Marcuzzi , as it is actually a synonym of Cyrtosoma (Nesocyrtosoma) tumefactum Marcuzzi.

Notes. Zayas (1988) described this species from five specimens of C. trinitatis collected at Las Lomas de Trinidad in 1963 and ten examples from Pico de Poterillo, both in Las Villas Province. As no holotype was designated for C. trinitatis , a lectotype is here designated; the specimen with a red Tipo label is chosen to be the lectotype . The remaining 14 specimens are here designated as paralectotypes.

Diagnosis. This species can be distinguished from all other species by the combination of the extremely short, convex body shape, extremely tapered elytra with rows of mostly discontinuous punctures ( Figs. 116, 117 ), and flat, apically truncate prosternal process ( Fig. 119 ).

Redescription (modified from Marcuzzi 1976) (male). 5.0–6.0 mm long, 3.5– 4.5 mm wide. Body extremely convex ( Fig. 117 ). Elytra broad anteriorly, tapered posteriorly ( Fig. 116 ). Darkly ferrugineous to black; antennae, mouthparts and tarsi ferrugineous. Head densely punctate dorsally; punctures smaller than single eye facet, slightly impressed; extremely short golden seta emerging from each puncture. Antenna weakly clavate, nearly filiform, antennomeres 6–10 weakly widened apically, forming a loose, elongate club; apical antennomere longitudinally ovate; antennomeres 6–11 with stellate sensoria. Mentum with acute median keel raised anteriorly to a point ( Figs. 10, 12 ). Ventral portion of eye not reaching subgenal sulcus ( Fig. 8 ); postgena without distinct punctures. Dorsal surface of pronotum densely punctate; punctures separated by 1.0–1.5 diameters. Pronotal marginal bead complete laterally, anterior and posterior margins with marginal bead effaced medially; anterior angles of pronotum acute, moderately produced and apically narrowly rounded; lateral edge of pronotum weakly sinuate at base; pronotum evenly convex ( Figs. 24 , 118 ). Hypomeron lacking distinct punctures. Prosternal process apically squarely truncate with marginal grooves opposite coxae not joined apically ( Fig. 119 ). Black, except under a microscope with light elytra appearing darkly ferrugineous with rows of black squares following elytral striae; elytral striae present as rows of medium sized punctures separated by 0.5– 1.0 3 diameter; elytral interstriae flat, densely punctate; scutellary striae short, indistinct, 1–3 punctures long; scutellum triangular, reduced ( Figs. 116, 118 ). Mesoventrite thin antero-posteriorly, almost flat, not receiving prosternal process; metaventrite,1/2 antero-postero length of mesocoxa ( Fig. 119 ). Metathoracic wing vestigial. Legs long, slender, punctate; apical 1/3 of femur reaching beyond edge of elytron; tibia slightly apically curved ventrally; metatibia with ventral apical tooth vestigial ( Fig. 45 ). Abdominal depressions on 4th and 5th ventrites reduced to slightly impressed slits ( Fig. 74 ); intercoxal process of first ventrite broadly rounded apically; ventral surface densely punctate, punctures moderately impressed ( Fig. 119 ).

Female. Identical to male, except metatibia straight and lacking apical tooth.

Biology. On a single specimen label, Darlington reported collecting this species by sweeping in the woods, but beyond this, there are no biological data available for this abundant species.

Distribution. This species is endemic to Cuba and has been collected in large numbers at 800 m in Topes de Collantes, the Trinidad Mountains in Sancti Spíritus Province ( Peck 2005). It has also been collected in large numbers at Buenos Aires in the Trinidad Mountains, an unlocated Darlington and Zayas collecting site ( Peck 2005). It has also been reported from Mina Carlota, another unlocated collecting site in the Trinidad Mountains ( Peck 2005). Finally, it has been collected at Soledad (east of Cienfuegos) and Cayamas (40 km NW of Cienfuegos) in Cienfuegos Province ( Figs. 258 , 265 ).
