Ordo: Coleoptera
Familia: Curculionidae
Name
Helleriella Champion, 1906b: 32 – Wikispecies link – Pensoft Profile
Type species
Helleriella longicollis Champion, 1906 [by monotypy].
Gender
Feminine.
Diagnosis
The slender rostrum (Fig. 50), elongate pronotum, linear scales, and a very short tibial uncus (Fig. 30) separates Helleriella from the zygopine genera with a concealed pygidium, flattened mesoventrite and second funicular article that is not longer than the first. The eyes are somewhat widely separated, especially near the top, strongly inflexed along outer margin towards bottom where it is sharply acuminate, the femora are non-carinate, with or without a ventral tooth, and are short and thick in some species.
Notes
The species of Helleriella have been suggested to belong to different mimicry complexes, including clytrine chrysomelids, Zacryptocerus ants, and possibly red-eyed flies and other species of ants (Hespenheide 1980[1]).
Phylogenetic relationships
Hespenheide (1980[1]: 330) suggests a relationship with Cylindrocopturus due to the “...elongate, compressed habitus... the pronotum distinctly narrower than the elytra, and an investiture of scales that are predominantly linear and only overlap end-to-end in contrast to broad, completely overlapping, encrusting scales of most Cylindrocopturus.”
Keys
Hespenheide 1980[1]: 329 and 1998: 3.
Host associations
Associated with several species of “swollen thorn Acacia” (Fabaceae: Mimosoideae DC.) (Hespenheide 1980[1]). Larvae live and feed in thorns not occupied by ants (Hespenheide 1980[1]).
Described species
Five species are known, including one described by Hespenheide (1998)[2].
Range
Mexico, Guatemala, El Salvador (Hespenheide 1980[1]: 325), Belize, Nicaragua, Costa Rica.
