Adesmus fortunei Lingafelter 2013

Adesmus fortunei is a species of beetle in the family Cerambycidae. It was described by Lingafelter in 2013.

Size: 9.7–13.8 mm long; 3.5–5.1 mm wide between humeri. Head with dense vestiture of appressed off-white setae, thickened at base, almost scale-like; most dense on frons, less dense around eyes, base of antennal tubercles and vertex. Punctures indistinct or hidden by pubescence. Frons not bulging, level to slightly convex between eyes with exception of small medial impression extending to vertex. Gena below lower eye lobe and mandibular base a little more than one-third height of lower eye lobe; frontal-genal ridge incomplete, not extending to eye margin; ante-clypeal sulcus transverse, but mostly hidden by pubescence. Eye large, bulging laterally on lower lobe, finely faceted, upper lobe connected to lower lobe by 3–4 facets at narrowest point, lower lobe much larger than upper lobe, occupying most of head from lateral view. Interantennal region moderately impressed with antennal tubercles moderately elevated. Antenna of female extending beyond elytral apex by 2 antennomeres (by 3–4 antennomeres in males). Antenna with fringe of denser, short pubescence of two colors, white and black, and scattered, less dense, longer setae. Antennomeres black with exception of third and basal one-fourth to one-half of fourth which are yellow. Antennomere 3 very long (longer than scape + 2, nearly as long as 4+5), subsequent antennomeres gradually decreasing in length. Prothorax cylindrical, much broader than long (1.8–2.8 mm long; 2.8–3.8 mm wide), distinctly narrower than elytral base, with very slight lateral swelling, densely covered with very pale green (nearly white) scale-like pubescence covering integument and any punctures; pronotum without dorsal calli or tubercles. Pronotum about one-fifth length of body. Prosternum densely pubescent with short, appressed, off-white setae; prosternal process broadly expanded at apex, closing procoxal cavities posteriorly. Elytron with distinct punctures on basal third, becoming shallow at middle, and inconspicuous or absent at apical third, bold, transverse purplish-black fasciae at basal fourth, just posterior to middle, and at apex. These transverse areas covered with narrow, suberect, non-scale-like black setae. Between and around the purplish-black fasciae are broad, transverse areas covered with short, dense, scale-like white or off-white setae. Humeri not projecting. Elytral apices narrowly rounded to suture, without spines. Elytron 7.2–9.7 mm long; 1.7–2.7 mm wide; elytral length/width: 3.7–4.2. Scutellum narrowly rounded posteriorly, with sparse pale green or white pubescence. Legs with femora and tibiae sublinear, only weakly thickened apically. Metafemur short, extending to about third ventrite, with moderately dense white and black pubescence not obscuring surface. Legs bicolored with protibia and venter of profemur yellow, mesotibia and metatibia yellow, and base of tarsomeres 1 and 2 yellow, all remaining portions of legs black. Venter mostly densely pubescent with metathorax and last 3 ventrites mostly covered in short, white pubescence, elsewhere mostly covered in black pubescence. Apex of fifth ventrite of males and females broadly truncate with small median notch.
