Lobobrachus cleidecostae sp.nov.

( Figs. 1, 3 , 11-12 , 19-21 )

Type material: HOLOTYPE ♂ ( MZSP 31405 ): “Brasil-PI [Piauí] / EstaÇão Ecológica UruÇuí-Una / 08°52′S / 44°57′W / 19-29.I.2001 / Montingelli, G.G. col” . PARATYPES: same data as holotype (3 ♀, MZSP 31406-31408).

Diagnosis: Lobobrachus cleidecostae sp. nov. is characterized by a combination of its coloration ( Figs. 11-12 ): greenish-copper with brassy, irregular patches on the pronotum; relatively more convex (subcarinate) odd-numbered intervals of the elytra; and median lobe of aedeagus ( Figs. 19-21 ) with apex strongly slanted, forming a right lateroapical projection at the tip, relatively thinner blade, and ostium slightly rotated to the left near base.

Description: As in genus description and body length: 23.8-26.0 mm; length of the elytra: 14.9-16.5 mm; humeral width: 6.5-7.5 mm. Coloration greenish-copper, with pronotum with irregular brassy patches and elytra with intervals 2, 4, 6 relatively flat and brassy; mouthparts, legs and ventral region black. Mandibles robust, pyramidal, and short with a short, broad scrobe. Antennae slightly longer than pronotum. Elytra elongate with lateral margins rounded; basal region wider than hind angles of pronotum; subapical region slightly constricted with apices conjointly prominent and rounded; intervals 3, 5, 7 strongly convex to subcarinate. Median lobe curved with distal margin strongly declivous, with one angle very prominent forming a rounded lobe; opening of ostium subelliptical, wider near apex, slightly inclined at middle of median lobe.

Etymology: The specific epithet is based on the name of Dr. Cleide Costa,a noted coleopterologist,whom the lead author had the privilege of working alongside for decades at the University of São Paulo Museum of Zoology.

Distribution: Brazil (Piauí state).
