A comparative anatomical study of Elateriformia and Dascilloidea (Coleoptera)

16. Dascilloidea Guérin-Meneville, 1843

“…Crowson (1950Crowson ( , 1955 suggested that a dascillid-like ancestor could have given rise to Scarabaeoidea, based manly on larval similarities, and later (1960) he formally moved the group into the series Scarabaeiformia. Kasap & Crowson (1975) provided evidence based on abdominal sclerites and musculature, alimentary canal, nervous system and internal reproductive organs of male and female to support a basal position for Dascilloidea outside Elateriformia.

15. Scirtoidea Fleming, 1821

“…Although the composition of the family is now generally agreed upon, Amplectopus was excluded by Kasap & Crowson (1975) who placed the genus in Chelonariidae based partly on the fusion of the first three ventrites. Lawrence & Newton (1995) considered the aedeagus to be of a distinctive type found only in Scirtidae.…”

18. Byrrhoidea. Teil 2

“…Hyphalus, Limnichus, Byrrhinus (= Pelocherops) and Caccothryptus with first three abdominal ventrites connate, with sutures appearing as relatively thick lines (Kasap & Crowson 1975). Paralimnichus with ventrites 1-4 connate but Brought to you by | Stockholms Universitet Authenticated Download Date | 8/24/15 9:31 PM not firmly jointed (the genus was considered to be a chelonarid by Kasap &Crowson 1975, andreturned to Limnichidae by Wooldridge 1983).…”

“…Kasap & Crowson (1975) removed the genus Lutrochus from Limnichidae (placed there at the time, although described as Dryopidae) and established a separate family for it. It was not until the work of Hinton (1939 a) was published that the family and subfamilies accepted at present were established, although some uncertainties remained.…”
