The light brown integument with diffuse areas of darker brown and white spots is distinct for the genus. Although there are no elytral tubercles, the presence at the base of each elytron of a small, circular spot of white pubescence anteriorly bordered with dark brown pubescence gives the impression of basal elytral tubercles as seen in other Lamiinae (e.g. Duocristala Lingafelter ). The other two Hispaniolan Acanthoderini/ Acrocinini , Oreodera glauca glauca (Linnaeus) and Steirastoma acutipenne Sallé , are easily distinguished by their apicolaterally spinose elytra (the elytral apices of O. nearnsi are subtruncate). Description. Holotype female. 12.8 mm long; 4.9 mm wide at humeri. Color : Integument of head, pronotum, elytra, and venter variably golden-brown to brown. Elytra with three diffuse, darker brown regions near base, near middle, and ante-apically, with the middle and ante-apical regions bordered anteriorly by diffuse, white pubescence. Each elytron with a small, white spot of pubescence at about the basal fourth, slightly closer to the suture than lateral margin, and bordered anteriorly by darker pubescence creating the illusion of a tubercle. Head. Broad, flattened and vertical anteriorly, with slightly elevated and widely separated antennal tubercles. Head (including antennal tubercles) impunctate, covered with short vestiture of mostly golden-brown pubescence. Eyes large with lower lobe occupying most of head from lateral view and elongate upper lobe connected by 5 rows of ommatidia. Upper eye lobes separated by little more than basal width of scape. Antennae extending beyond elytral apices by two antennomeres. Antennomeres filiform, unexpanded at apices (except clavate scape), and covered with vestiture of short golden-brown pubescence, subtly lighter and off-white at basal half of antennomeres 4–7. Scape extending to midpoint of pronotum, third antennomere longest, about 1.5 × longer than scape; 4–9 successively shorter; 10–11 slightly longer than 9 and subequal to one another. Thorax. Pronotum broader than long with pronounced lateral tubercles at middle of sides which are angled upward at their apices. Small, anterolateral dorsal tubercles present. Sparse, well-defined punctures present around dorsal tubercles and along posterior margin to behind lateral tubercles; otherwise impunctate and covered with golden-brown and dark brown pubescence forming diffuse patterns. Only a few longer setae present, primarily on posterior margin of lateral tubercles. Prosternal process very broad, over half as broad between procoxae as width of procoxa and with apex flat, expanded, gradually notched at middle and over 1.5 × as wide as each coxa. Apex of prosternal process with fringe of white pubescence, otherwise prosternum and mesosternum coated with mixture of short, golden-brown and white pubescence and mostly impunctate. Elytra with humeri slightly produced laterally and apices subtruncate, lacking dorsal tubercles; with variably sized punctures throughout, slightly denser at base than apex, but all separate from one another. Elytra with very few elongate suberect setae and completely covered, except for punctures, with vestiture of dense, short, appressed setae. Scutellum very broad at base, 1.5 × wider than space between upper eye lobes, with subtruncate posterior margin; covered in dark brown pubescence. Femora clavate; hind femur extending to apical fourth of elytral apices. Mesocoxae separated by very broad mesosternal process that is greater than the width of mesocoxa. Abdomen. Covered with mixture of short, appressed, golden-brown and white pubescence. Fifth ventrite nearly as long as three preceding ventrites combined and narrowed at apex. Type material. Holotype (female): DOMINICAN REPUBLIC : La Vega Province , Parque Nacional José Armando Bermúdez , 1–3 km along trail W. of La Ciénaga , 900–1000 m , beating, specimen ID: 7612, Nearns & Lingafelter , 24 June 2005 ( ENPC , donated to USNM ). Etymology. This species is named after Eugenio Nearns, my friend and colleague who collected the holotype . Remarks. This endemic Hispaniolan species is known from only the holotype which was taken by beating foliage along the lower trail at the base of Pico Duarte in the Cordillera Central. Biological information is unknown. There is some disagreement on the tribal placement of Oreodera . Souza et al. (2020) made a phylogenetic analysis that showed Oreodera should be placed in Acrocinini and not Acanthoderini. Heffern et al. (2023) showed that some features used to distinguish Oreodera from Acanthoderini are variable within Oreodera . Figure 23. Oreodera nearnsi Lingafelter , new species . Digital painting of holotype by Taina Litwak. APOMECYNINI Thomson, 1861 Acrepidopterum Fisher, 1926 Remarks. Members of this genus are very small, rarely longer than 4 mm , and have a dense vestiture of pubescence on the elytra and pronotum. The base of the elytra is usually slightly swollen and slightly depressed behind. The procoxal cavities are closed posteriorly. Some members of Desmiphorini are similar (e.g., Eupogonius LeConte and Estola Fairmaire and Germain ), but those genera have small, acute, pronotal tubercles situated laterally at the sides and/or antennae and legs clothed with dense, long setae. Acrepidopterum are easily distinguished from similarly-sized members of Adetaptera by having fully developed hind wings and having the metasternum as long or longer than the first abdominal ventrite (shorter in Adetaptera ). Note that some species in this genus (as with many genera of Apomecynini) need to be reassigned based on revised systematic concepts presented in Santos-Silva et al. (2019) . For example, the Cuban Acrepidopterum acutum Zayas has characters of flightlessness and a reduced metasternum that suggests it may be more appropriately assigned to Adetaptera ) (see figures in Devesa et al. 2019 ).
