Name
Eumorphus Weber, 1801 – Wikispecies link – Pensoft Profile
Type species
Eumorphussumatrae Weber, 1801 (= Erotylusquadriguttatus Illiger, 1800).
Diagnosis
Eumorphus is most similar to Platindalmus and Gerstaeckerus, but is distinguished from these by the following combination of characters: 1) lateral margin of pronotum with a tendency to form irregularly broken lines, inconsistent and often asymmetrical; 2) apex of mandibles narrowly chisel-shaped; 3) basal margin of elytra simple; 4) intercoxal process of mesoventrite subparallel-sided; 5) male femora lacking fringes of long hairs on inner edges (after Tomaszewska 2005[1]).
The Eumorphusmarginatus group (sensu Strohecker 1968[2]) is characterized as follows: large body size; elytra with lateral flattened margins wide, elevated dorsally in mesal part in male; male fore tibiae with sexual dimorphism.
Biological notes
Eumorphusmarginatus Fabricius, 1801 was collected from Polyporus sp., and living individuals apparently have a strong unpleasant smell, much like that of the seeds of Parkiaspeciosa (after Arrow 1925[3]). The larva of Eumorphusquadriguttatus (Illiger) was described by Bugnion (1909)[4] and Hayashi (1986)[5], and Tomaszewska (2005)[1] provided a description of the larva of a Eumorphus sp. with figures.
