RHIPICERIDAE Author: John F. Lawrence, 2001. Classification Suborder Polyphaga, Series Elateriformia, Superfamily Dascilloidea. Description Antenae with 11 segments, pectinate or flabellate in males. Antennal insertions exposed or concealed. Visible portion of procoxa projecting bellow prosternum with the trochantin at least partly exposed. Procoxal cavity externally open and internally open. Mesocoxae separated by less than 0.4 X coxal width, with mesocoxal cavity laterally open. Tarsal formula 5-5-5. Numberof ventrites 5 with 2 connate. Body length 10-15 mm. Body elongate but stout, pubescent. Tarsi with lobes on 1-4. Empodium large and multisetose. Head with raised antennal insertions, projecting, sharply bent mandibles and no visible labrum. Quick identification Rhipiceridae includes relatively large, distinctive looking beetles with pectinate antennae. The Callirhipidae are most easily confused with rhipicerids and both have a large multisetose empodium between the tarsal claws (second figure). Rhipiceridae differ from Callirhipidae in having a longer head with projecting mandibles, reduced, membranous labrum and free abdominal ventrites.
