description: Erymanthus Spinola, 1841
Type species: Erymanthus gemmatus Klug, 1842
Spinola 1841: 75; Klug 1842: 327; Lacordaire 1857: 457; Desmarest in Chenu 1860: 269; Schenkling 1903: 28, 64; Corporaal 1949: 355; Opitz 2010: 66.
Head: Head including eyes wider than base of pronotum, eyes coarsely facetted, reniform, protruding laterally, deeply emarginated at antennal insertion, separated by one to two eye widths, ocular notch distinct; frons with two grooves or two gibbosities; labrum bilobed, terminal segment of labial palpomeres securiform; terminal maxillary palpomeres spatulate, widened distally; gular sutures apically converging, gular process broad with two papillae (Fig. 1); antennae comprised of 11 antennomeres; antennomere 1 with one long hair; antennomeres 2–8 filiform, 9– 10 triangular, 9–11 forming a distinct club with dense light pubescence; male specimens with a small pit-like sensilla on antennomere 11 (Fig. 2).
Thorax: Procoxal cavities closed behind; pro-intercoxal process narrow, broadly dilated posteriorly (Fig. 3); pronotum longer than broad; pronotum subparallel, widest in middle, basal collar conspicuously narrower, pronotal arch slightly narrower, sometimes with strong lateral gibossities; pronotal disc with more or less conspicuously gibbosities and always with a longitudinal elongate-ovate groove centrally; mesocoxal cavities open laterally; anterior mesoventral process present, forming a small convexity; intercoxal mesoventral process more or less wide, protruding laterally; mesepisternum with fine punctation anteriorly, surface smooth posteriorly; scutellum oblongovate; hypomeron tapering apically towards intercoxal process, forming a typical “edge” towards base; metendosternite with conspicuous furcal arms, laminae broadly triangular (Fig. 4).
Elytra: Elongate, almost two times longer than broad, base not margined, usually with strong humeri; apex strongly dilated, declivous; elytral punctation in basal part arranged into ten striae, punctation behind humeral part mostly irregular; punctation crateriform, circular to oblong-ovate, sometimes rasp-like; in the posterior part many gibbosities without regular arrangement; posterior half usually with five large gibbosities with dense setae and more or less regular distribution (Fig. 6); hind wing with AA3+4 and CuA2 absent (hence wedge cell absent), MP4 absent or with vetige evident at junction of MP3 and MP3+4.
Legs: Legs stout, femora conspicuously swollen, especially profemora; pro- and mesotibiae strongly bent, metatibiae only slightly bent, almost straight; carinae of pro- and mesotibiae over entire length, carinae of metatibiae extending from two-thirds to full length; inner edge of pro- and mesofemora and -tibiae with a row of short, thick bristles; claws simple; tarsal pulvillar formula 3–3–3; pulvilli deeply bilobed; tibial spur formula 1–1– 1 or 1–2–1 (E. pustulatus only).
Abdomen: Six visible abdominal ventrites; abdominal metaintercoxal process narrow; pygidium broadest at the beginning of the processes, pygidial index (PL:PW) between 1:0.8 and 1:1; tegminal struts conspicuously long and variable in shape and width.
