8.2. Subgenus Fulvotrechus, subgen. nov. (type species Xylotrechus stebbingi Gahan,
1906: 244 [17]) – Body elongated, subcylindrical, with a pale and non-contrasting hair
pattern of transverse stripes. Integument brown. Head short, forehead wide, slightly
attenuated anteriorly, with V-shaped longitudinal carina. Antennae short. Pronotum
subspherical, enlarged, with rough sculptured central band of chitin grains and one or two
round lateral spots. Elytra parallel, apically rounded, with acute spine on the outer edge of
apex. Diagnosis: Integument fulvous; pronotum enlarged with rough sculptured central band
of chitin grains and one or two round lateral spots. Etymology: fulvus – fulvous + τρέχω – to
run.

8.3. Subgenus Hieroglyphotrechus, subgen. nov. (type species Clytus antilope
Schönherr, 1817: 465 [62]) – Body elongated, subcylindrical, slightly widened, with
contrasting hair pattern of transverse stripes. Head short, forehead wide with two poorly
emerged longitudinal carinae. Antennae widely spaced on the forehead, short, reach first third
of elytra. Pronotum subspherical, enlarged, with a rough sculpture of small transverse
wrinkles. Elytra parallel, apically rounded, with acute spine on the outer edge of apex.
Diagnosis: Pronotum roughly sculptured of small transverse wrinkles; forehead with two
poorly emerged longitudinal carinae. Etymology: hieroglyphicus – hieroglyphic + τρέχω –
to run; Drapiez described Clytus antilope as Callidium hieroglyphicum [14].

8.4. Subgenus Igneotrechus, subgen. nov. (type species Xylotrechus pyrrhoderus
Bates, 1873: 200 [3]) – Body elongated, subcylindrical, slightly widened, with contrasting
hair pattern of transverse stripes. Integument black except red (occasionally black) pronotum.
Head short, forehead slightly narrowed with three poorly emerged longitudinal carinae:
central longitudinal and two lateral form a V-shaped figure. Antennae widely spaced on the
forehead, short, reach elytral humeri. Pronotum subspherical, enlarged, with a rough
sculpture. Elytra parallel, apically rounded, with acute spine on the outer edge of apex.
Diagnosis: Pronotum red; forehead with three poorly emerged longitudinal carinae.
Etymology: igneus – fiery + τρέχω – to run.

3. Tribe Chlorophorini, trib. nov.
Cyllenes Leconte & Horn, 1883: 302 [37], syn. nov.
Type genus: Chlorophorus Chevrolat, 1863: 290 [10]
Description: Body significantly elongated, subcylindrical, with a hair pattern of spots
and transverse stripes. Head slightly elongated, clypeus well developed. Forehead narrowed
with closely spaced antennae bases. Antennae elongated, reach at least the middle of elytra.
Pronotum subspherical, transverse or oblong. Elytra elongate, parallel, apically truncated.
Legs elongated. Femora gradually thickened posteriorly. Metepimera 4 times longer than
st
wider, extend over hind angles of the 1 ventrite.
Diagnosis: Forehead narrowed with closely spaced antennae bases; clypeus well
developed; metepimera 4 times longer than wider.
