03B0B164090BBD09B8CAFDCAB18A2DEE.taxon	discussion	Remarks. This species is very similar to Laemophloeus incisus Sharp, 1899 (Figs. 2 B, E; 3 E, F; 4 C) and L. assignatus Bremer, 2025 because of the elytra uniformly light testaceous, not infuscate, antennal emarginations of clypeus incised, club antennomeres simply pubescent, and antennomere 11 elongate (only in major males of L. incisus). However, Laemophloeus claudioruyi sp. nov. is easily distinguished from L. incisus in the following respects (characters of L. incisus parenthesized): antennal scape entirely cylindrical (scape with posterior face flat or slightly concave); antennomere 3 short, 1.3 times longer than pedicel (elongate, almost twice longer than pedicel); anterior margin of clypeus with mandibular and labral emarginations U-shaped (anterior margin of clypeus somewhat Mshaped, with mandibular and labral emarginations almost straight); frontoclypeal suture deeply impressed laterally and effaced at middle (frontoclypeal suture indistinct); lateral margins of pronotum with small, distinct antebasal denticle (lateral margins of pronotum without antebasal denticle); procoxal cavities closed (procoxal cavities widely open); aedeagus with parameres fused to basal piece and fused to each other at midline (parameres not fused to basal piece and completely separated from each other). In addition, Laemophloeus claudioruyi sp. nov. shares with L. assignatus the anterior margin of clypeus with mandibular and labral emarginations U-shaped, but it is distinguished by (characters of L. assignatus parenthesized): frontoclypeal suture deeply impressed laterally and effaced at middle (frontoclypeal suture complete, V-shaped); lateral margins of pronotum with small, distinct antebasal denticle (lateral margins of pronotum without antebasal denticle); procoxal cavities closed (procoxal cavities widely open); and parameres short and barely acute at apex (parameres elongate, slender, sharply acute at apex).	en	Bento, Matheus, Rafael, José Albertino (2025): Two new species of the lined flat bark beetle genus Laemophloeus Dejean (Coleoptera: Cucujoidea: Laemophloeidae) from Amazonia.

03B0B1640909BD0DB8CAFAFAB1232B32.taxon	discussion	Remarks. Among all the species within Laemophloeus (s. str.) possessing 3 - segmented antennal club, Laemophloeus obeliscus sp. nov. is superficially similar to Laemophloeus capitesculptus Thomas, 2014 and Laemophloeus corporeflavus Thomas, 2014 (Figs. 3 C, D; 4 B) because of their general appearance, dorsal color mostly testaceous, and clypeal emarginations shallow. However, the new species can be separated from both by: frontoclypeal suture complete, deeply impressed (laterally effaced, not complete in L. capitesculptus; absent in L. corporeflavus); antennal emarginations of clypeus present (absent in L. capitesculptus; present in L. corporeflavus); male antennomeres 4 – 10 moniliform (elongate); second elytral cell closed (open in L. capitesculptus and L. corporeflavus); procoxal cavities closed (narrowly open L. capitesculptus and L. corporeflavus); male tarsal formula 5 - 5 - 4 (5 - 5 - 5 in L. capitesculptus; 5 - 5 - 4 in L. corporeflavus); and endophallus with a long, filament-shaped apical sclerite (flat, hairy apical sclerite in L. capitesculptus; shared with L. corporeflavus).	en	Bento, Matheus, Rafael, José Albertino (2025): Two new species of the lined flat bark beetle genus Laemophloeus Dejean (Coleoptera: Cucujoidea: Laemophloeidae) from Amazonia.
