Roy Albert Crowson (22 November 1914 – 13 May 1999) was a British biologist who specialized in the taxonomy of beetles. ... Genera Hydroscapha Scaphydra Yara The skiff beetles are a small family (Hydroscaphidae) of water beetles, consisting of 13 species in three genera. ... Species (19 species) The minute bog beetle is a small and obscure family (Sphaeriusidae) of beetle typically found along the edges of streams and rivers, where it feeds on algae. ...
This smallest suborder of Coleoptera consists of four families of small-to-minute beetle. They have notopleural sutures, though on some families the sutures may be difficult to see. For other uses, see Beetle (disambiguation). ... Suborders Adephaga Archostemata Myxophaga Polyphaga many subgroups: see Subgroups of the order Coleoptera Beetles (order Coleoptera) are one of the main groups of insects. ...
The members of this suborder are aquatic and feed on algae. The algae (singular alga) comprise several different groups of living things that produce energy through photosynthesis. ...
Myxophaga contains about 100 described species in four families, mostly very small, including skiff beetles (Hydroscaphidae) and minute bog beetles (Sphaeriusidae).
Their phylogenetic relationship is uncertain, with the most popular hypothesis being that Polyphaga and Myxophaga are most closely related, with Adephaga an outgroup to those two, and Archostemata an outgroup to the other three.
The extraordinary number of beetle species poses special problems for classification, with some families consisting of thousands of species and needing further division into subfamilies and tribes.
Evidence for the relationship of Polyphaga and Myxophaga in this phylogeny is based on a shared reduction in the number of larval leg articles.
Evidence for the Polyphagan relationship to the remaining suborders is based on characters of wing venation and articulation (Kukalova-Peck and Lawrence, 1993).
This new phylogeny placed Polyphaga sister to Adephaga with Myxophaga sister to the Polyphaga+Adephaga clade and Archostemata sister to the rest of the suborders (Figure 5).
