The Diorymerina are a diverse group of baridine weevils with a concealed pygidium, and interruptions between the surfaces of the prosternum and meso- and metaventrites. The rostrum is diverse in form but never much longer than head and pronotum combined, and the prosternum either lacks a rostral channel or has it extending past the procoxae to the mesoventrite (Legalov 2018). Historically, the subtribe has been restricted to forms with an extremely high rounded upper profile. However, it was expanded by Legalov (2018) to cover a more diverse assemblage of species, including examples with elongate-oval and rhomboidal body forms. Species are associated with a wide range of plant hosts; some are notable agricultural pests.
Weevil ball
Published 3 May 2010
The Diorymerina are a South American subtribe of the weevil subfamily Baridinae. Alonso-Zarazaga & Lyal (1999) include ten genera in the Diorymerina according to the International Weevil Community Website* (though this listing differs slightly from that given by Casey 1922) but available info on members of the group appears to be rather sparse to almost non-existent. Which is a pity because they are certainly eye-catching animals.
*I do think it rather neat that there’s an “International Weevil Community”.
Baridinae as a whole are characterised by a rounded body shape but in the Diorymerina this is taken to an extreme. The dorsal profile of diorymerins is highly arched, almost circular, and at least some diorymerins have bodies nearly as deep as they are long (Casey 1922; Davis 2009). All members of the Diorymerina are glossy in appearance and usually such colours as black or mahogany brown though Bonomius aeneoviridis is a bright metallic green. The beak of diorymerins is usually relatively short and stout compared to other weevils.
Lima (1956) recorded species of Diorymerina feeding on shoots and seeds of Malpighiaceae trees but other than that most species seem not to have been touched on since their original morphological descriptions, and even those are scattered and difficult to locate. Significant landmarks appear to be Casey (1922) and Hustache (1950), the latter being the first part of the rather unpleasant ‘Nouveaux Barinae Sud Américains’. Most of this publication’s eccentricities may perhaps be excused by its unusual publication history (Kuschel 1983): while the original manuscript was prepared in 1929, it languished for twenty years due to lack of funding and was not published until after the author’s death. Nevertheless, the four parts together add up to over three hundred pages of bare species descriptions with absolutely no illustrations, usually no explicit comparisons with previously described taxa and a whole universe of typological errors.
Entering Hiotus
Published 14 April 2025
In 1922, the American entomologist Thomas L. Casey published his memoir on the Brazilian Baridinae, a massive 520-page work that remains the primary reference for many South American representatives of this diverse assemblage of weevils. Among those taxa covered by Casey were the species that he assigned to the subgenus Melanolia.
Casey established Melanolia for eighteen species of his diverse genus Hiotus. They are all small weevils, most less than four millimetres in length (one, H. globosus, was a comparative giant at nearly five millimetres). All are uniform in appearance, being globose weevils with a remarkably convex form and entirely black, highly polished integument. The species are distinguished by structural features: the prominence of the striae on the elytra, the development of punctation on the pronotum and elsewhere, the shape of the scutellum, etc. Some, such as the appropriately named H. foveiceps and H. cavifrons, are marked by a deep excavation on the front of the head. Hiotus rostralis has an unusually long and thin, nearly straight, beak that contrasts with the thicker, more curved beak of other species.
Hustache (1949) later described seven further species, most also from Brazil though some originated in French Guiana, Bolivia and Argentina. One species, Hiotus rufitarsis, managed to buck the uniform in the possession of red tarsi. The Bolivian species, H. foveifrons, was one of the smallest Melanolia species, only two millimetres in length.
And that appears to be pretty much it for Melanolia. Kuschel (1983) noted that Hustache’s Hiotus distortus was the same species as Casey’s earlier H. gentilis, but the species appear to have otherwise not garnered attention. Nothing seems to be known of their natural history, and subsequent collections (if any) seem to have gone unrecorded. Even Casey’s original descriptions were based on limited material: many of his species were represented by only single specimens. Whether this indicates an actual rarity of these species in the wild, or is merely a reflection of the limited studies on tropical South American weevils, is something that would demand further investigation.
Systematics of Diorymerina
Characters (Casey 1922, as Diorymerini): Body exceedingly convex, smooth, glabrous, without trace of scaly covering at any point, and at most, and very rarely, a few erect setae. Beak moderate in length, frequently notably short. Prosternum deeply and abruptly canalate, often capable of receiving the beak but not snugly. Femora subparallel, not spiculate beneath, sulcate along their under surface; tibiae generally angulate externally near base. Coloration usually deep black to piceo-rufous in whole or in part, rarely with a bright green metallic lustre.
