Diagnosis.

1.8-2.2 mm (mean = 2.1 mm; n = 5), 3.0-3.14 × as long as wide. This species is distinguished by the elytral apex attenuate and weakly emarginate, declivital interstriae 1-3 denticulate, interstriae 2 with fewer denticles than interstriae 1 or 3, and posterolateral margin of declivity costate, armed with two denticles.

Distribution.

Brazil ( Paraná *, Santa Catarina), Ecuador* (Los Ríos), Mexico (Oaxaca, Tabasco, Veracruz), Panama ( Colón, Panamá *), Peru (Madre de Dios), Suriname, Venezuela (Barinas, Mérida).

Biology.

This species has only been recorded from Guazuma ulmifolia ( Malvaceae ) ( Wood and Bright 1992) and an unidentified Malvaceae . Wood (1982) reported collecting specimens from new tunnels in recently cut limbs and boles 5-20 cm in diameter.

Remarks.

The holotype of X. catulus was not directly examined by the authors. Our concept of the species is based Blandford’s (1898) description, and a specimen compared to the holotype by S.L. Wood in 1972 with the following locality: Panama, 24.V.[19]49, wood with orchids, mobile [phone] (NMNH).
