Epicallichloris Gutiérrez, 1951. Type species
Callichloris alticola Gutiérrez, 1951 by

Gender: feminine.
DESCRIPTION. Length 10.5-34.0 mm,
width 6.2-19.3 mm. Color usually lime green
to olive green or yellow, sometimes dark green
or brown to black. Body usually ovate,
strongly to weakly convex. Head: Dorsal surface
punctate, usually glabrous. Clypeal apex
rounded to trapezoidal. Frontoclypeal suture
complete or obsolete medially. Labrum projecting
ventrally, perpendicular to clypeus.
Apex of labrum with medial tooth. Mentum
apically with notch or medial tooth. Antenna
9-segmented or 10-segmented. Pronotum:
Surface usually glabrous, always punctate.
Marginal bead weak laterally, usually absent
elsewhere. Elytron: Surface glabrous; longitudinal
striae impressed or not impressed,
punctate or impunctate. Suture apically
rounded, angled, or with acute spine. Pygidium:
Surface convex, punctate, setose. Venter:
Thorax setose. Mesothoracic process
present, often projecting anteriorly to
procoxa. Abdomen sparsely setose or glabrous.
Apical spiracles sometimes extruding.
Legs: Protibia with 1-3 teeth. Protarsomeres 2-
4 wider than long, cup-shaped. Protarsomeres
3-4 in males often with internoapical stridulatory
ridge. Protarsomere 5 in males often with
internomedial, stridulatory tooth. Unguitractor
plate cylindrical with 2 setae. Modified
protarsal claw in males thickened, elongate
when compared with other claw, apex unevenly
bifurcate. Modified protarsal claw in
females with ventral tooth, not thickened.
Modified mesotarsal claw weakly thickened,
elongate when compared with other claw,
apex unevenly bifurcate or with ventral tooth,
not thickened. Modified metatarsal claw elongate
with ventral tooth, not thickened. Male
Genitalia: Phallobase not fused with
parameres. Parameres not fused but longitudinally
contiguous. Female Genitalia: Generally
not diagnostic.
LARVAE. Our knowledge of Platycoelia larvae
is scant. Ohaus (1908, 1909a) published
some rudimentary observations of P. gaujoni
