Species notes from the sources
Etymology: Cryphalus striatulus Mannerheim, 1853 Note from Tom Atkinson: The type of Trypophloeus striatulus (Mannerheim, described in genus Cryphalus ) was thought lost and the species was misidentified by everyone as a species of Trypophloeus . Mandelshtam found the type in Leningrad (where most of Mannerheim's material was deposited) and realized the error. It is actually a species of Cryphalus . Correction of the error and misidentifications by the rules of the ICZN causes a cascading series of name changes. What we all treated as Trypophloeus striatulus (Mannerheim) is now Trypophloeus nitidus (Swaine) and what we treated as Cryphalus ruficollis Hopkins is Cryphalus striatulus Mannerheim.
About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Cryphalus striatulus. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
