Diagnosis

2.5−4.2 mm long and stout (2.06−2.3 times as long as wide). Eccoptopterus can be distinguished by the robust pronotumpronotum:
the dorsal surface of the thorax
almost as large or larger than abdomen; pronotalpronotal:
pertaining to the pronotum
basebase:
point or edge closest to the body; opposite of apex
bearing a dense tuft of setae; pronotalpronotal:

discdisc:
the flat central upper surface of any body part (e.g. pronotum and elytra)
asperateasperate:
covered in asperities
; elytraelytron:
the two sclerotized forewings of beetles that protect and cover the flight wings
excavated with denticlesdenticle:
a small tooth, the sides of which are equal and the tip is above the middle of the base
around the margins and by the metatibiae conspicuously enlarged and flattened. In addition, the scutellumscutellum:
a shield-like sclerotized plate located at the midpoint of the elytral base 
is flush with elytraelytron:
the two sclerotized forewings of beetles that protect and cover the flight wings
and flat, and the procoxae are contiguous.
