Abstract: The male of Adesmus murutinga Martins & Galileo, 2004 is described for the first time, an updated key to Colombian species of the genus is presented, and three species of longhorned beetles are reported for the first time for Colombia. The specific localities in Colombia of Miriclytus quadrifasciatus (Chevrolat, 1862) and Oedudes spectabilis (Drury, 1782) are reported.

Keywords: Biogeographic Chocó, Distribution, New records, Taxonomy.

Resumen: Se describe por primera vez el macho de Adesmus murutinga Martins & Galileo, 2004, una clave actualizada de las especies colombianas del género es presentada, además se reportan para Colombia tres especies de escarabajos longicornios. Finalmente se detallan localidades específicas en Colombia de Miriclytusquadrifasciatus (Chevrolat, 1862) y Oedudes spectabilis (Drury, 1782).

Palabras clave: Chocó Biogeográfico, Distribución, Nuevo registro, Taxonomia.

The tribe Hemilophini Thomson, 1868 is uniquely American, represented by 571 species in 131 genera (Tavakilian & Chevillotte, 2023). Morphologically, it is characterized by having finely granulated eyes, lower eye lobes shorter or the same lenght as the genae and tarsal claws bifid. Some species mimic other families of Coleoptera such as Lycidae and Cantharidae (Martins & Galileo, 2014).

The genus Adesmus Lepeletier & Audinet-Serville, 1825 is composed of 68 species distributed in the Neotropical region, being one of the most diverse genera of Hemilophini (Monné, 2023b). It is distributed from Mexico to South America, including the Caribbean. In South America, the species of Hemilophini occur mainly in the Amazon Forest and Atlantic Forest (Martins & Galileo, 2014).

Currently, six species are recorded for Colombia (Martínez 2000; Martins & Galileo 2014; Botero 2018; Monné, 2023b): Adesmusdiana (Thomson, 1860); A. divus (Chabrillac, 1857); A. laetus (Bates, 1881); A. leucodryas (Bates, 1881); A. murutinga Martins & Galileo, 2004; and A. pirauna Galileo & Martins, 1999.

Adesmus murutinga was described by Martins & Galileo, 2004 based on a single female specimen from Colombia. Herein, we describe and illustrate for the first time the male of A. murutinga; an updated key to Colombian species of the genus is provided. Additionally, three species are reported for the first time from Colombia belonging to Cerambycini, Torneutini, and Trachyderini. Detailed localities in Colombia for Miriclytus quadrifasciatus (Chevrolat, 1862) and Oedudesspectabilis (Drury, 1782) are provided.

Measurements were made using tpsDig v. 2.26 software and units are in millimeters (mm). Photographs were taken using a Nikon D3200 camera, with 18–55 mm macro lens. The following references were used for the identification of the species: Martins & Galileo (2014); Martins & Galileo (2011); Santos-Silva et al., (2018); Joly (2017); Monné & Monné (2013); and the original descriptions.

Adesmus murutinga Martins & Galileo, 2004

Male (Fig. 1a-d) Head decumbent, completely covered by white pubescence. Frons transverse with a black triangular macula close to clypeus; region between upper eye lobes with transverse black pubescent band. Distance between upper eye lobes 0.34 times length of scape; in frontal view, distance between lower eye lobes 0.90 times length of scape. Clypeus truncate; apical margin truncate. Labrum convex brownish, glabrous. Mandibles black. Labial and maxillary palpomeres orange. Antennae surpassing elytral apex at antennomere VII; with long, erect white setae on inner side. Scape subcylindrical. Antennal formula based on length of antennomere III. Scape = 0.30; pedicel = 0.11 IV = 0.71; V = 0.51; VI = 0.46; VII = 0.38; VIII = 0.35; IX = 0.31; X = 0.22; XI = 0.20.

Thorax: Prothorax wider than longer. Pronotum covered with white pubescence, with a transverse black pubescent band centrally. Prosternum, mesoventrite, metaventrite, and metanepisternum with dense white pubescence. Elytra. Each elytron with a pair of circular black pubescent maculae, located on apex of anterior third, another on beginning of posterior third, posterior one greater than anterior. Humeral carina reaches posterior 2/3 of elytra. Legs. Femora orange; tibiae cylindrical, orange basally, black apically. Abdomen. Urosternites II to IV covered with dense white pubescence; urosternite with V orange pubescence, concave on apical margin.

Dimensions: male (mm). Total length, 15.10; prothorax: length, 3.35; anterior width, 4.35; posterior width, 4.45; widest prothoracic width, 4.65; humeral width, 6.30; elytral length, 10.40.

Material examined: Colombia, Valle del Cauca, bajo Calima, 70 m. Colecta manual, 1 male, 13/VI/2010, A. Silvestre col. (MENT-UT).

Remarks: Examination of the female holotype (Fig. 1e-i) shows that the most significant difference between females and males is the diameter of the elytral maculae. According to Martins & Galileo (2004), A. murutinga is similar to A. piraunaMartins & Galileo, 2004 but differs by the scape shape (subcylindrical), body color (white and black), and tarsal and antennal colors (black).

Distribution of Adesmus in Colombia

Adesmus divus is distributed in the Caribbean region of the departments of Atlántico and La Guajira (Audureau 2017; García et al., 2021); A. diana occurs in the Orinoquia, specifically in the departments of Casanare and Meta (Martins & Galileo 2004); and the other three species are recorded in the biogeographic Chocó, departments of Chocó (A. pirauna) and Valle del Cauca (A. leucodryas; A. murutinga; A. pirauna) (Martins & Galileo 2004; Martins & Galileo 2014) (Fig. 2).
