Antitypona submetallica (Jacoby, 1890)

( Figs. 1a , 3c )

New species record: JGZC: male ( JGZC-1211 ), Granada, Reserva Silvestre Privada Domitila , May 2010, J.-M. Maes leg., Antitypona submetallica (Jac.) J. Gómez-Zurita det. 2022 .

There is some confusion about the limits between the genera Antitypona and Lamprosphaerus , two genera of typically small, roundish, and metallic beetles with a facies similar to Spintherophyta and Brachypnoea , but without clavate antennae. Both genera can be somewhat distinguished by the shape of hypomera, longitudinally indented in Lamprosphaerus and relatively convex in Antitypona ( Weise 1921) , and also by the degree of inclination of epipleura, horizontal in Lamprosphaerus and slanted, visible laterally in Antitypona ( Flowers 1996) . A single male specimen from Nicaragua (nearly 3 mm long) is very similar to the female type specimen of A. submetallica (Jacoby, 1890) except in the marked dorsal metallic green color and the antennae more slender and nearly entirely pale (except last antennomere), but the latter also show the enlarged pedicel and short and fine antennomeres 3–4 as in the type and the same fine punctation on head and pronotum over microreticulated background ( Fig. 1a ). This male is tentatively classified as Jacoby’s species, also taking into account that all the other species of Antitypona , except the characteristic A. apicalis (> 3.5 mm), are much smaller (<2.6 mm), but the penis is figured to allow for future assessment of our interpretation ( Fig. 3c ). The species is known from Costa Rica and Panama ( Flowers 1996), and the Nicaraguan record would extend the range of the species to the north.
