Calanticomorpha

description: † ORDER CALANTICOMORPHA ORD. NOV.   Diagnosis: Capitulum with three to five pairs of larger lateral plates; subrostrum and subcarina usually present; smaller laterals variably developed, often absent.   
 Comment: Calanticomorpha are a paraphyletic assemblage of pedunculate forms, which are sister taxa to the Cretaceous–Recent Scalpellidae; only the Calanticidae survive to the present and represent a morphologically diverse group, which is shown to be monophyletic from molecular analyses (Lin et al., 2015).   
††FAMILY CRETISCALPELLIDAE BUCKERIDGE, 1983 (CRETACEOUS)  
 Diagnosis: Eighteen plates in capitulum (paired scuta, terga, upper latera, rostrolatera, inframedian latera; carinolatera (two pairs), one subcarina.   
 Comment: Cretiscalpellidae form a sister group to the Scalpellidae, which evolved from them by loss of the subcarina and lower pair of carinolatera (Gale et al., 2019).   
 †† Cretiscalpellum Withers, 1922 (nine species)   
 †† Jagtscalpellum Gale, 2020 (five species)   
 †† Striascalpellum Gale, 2020 (four species)   
 †† Witherscalpellum Gale, 2020 (two species)   
††FAMILY TITANOLEPADIDAE GALE IN GALE & SØRENSEN, 2015 (CRETACEOUS)  
 Diagnosis: Twelve plated capitulum (paired scuta, terga, rostrolatera, inframedian latera, carina, subcarina, rostrum and subrostrum). Tergum and scutum possessing interlocking apical processes; scutal umbo subapical to central, all other umbones apical.   
 †† Ivoelepas Gale in Gale & Sørensen, 2015 (six species)   
 †† Levelepas Gale in Gale & Sørensen, 2015 (one species)   
 †† Titanolepas Withers, 1913 (three species)   
†FAMILY CALANTICIDAE ZEVINA, 1978 (CRETACEOUS–RECENT)  
 Diagnosis: Number of plates highly variable (Jones & Hosie, 2009); usually with three pairs of larger laterals (rostrolatus, upper latus and carinolatus), often with subrostrum and subcarina; inframedian latus probably absent.   
 Comment: Monophyletic in molecular analyses.

† ORDER SCALPELLOMORPHA BUCKERIDGE & NEWMAN, 2006  
 Diagnosis: Monophyletic by molecular analyses (except in the study by Herrera et al., 2015). Plesiomorphically, 14 plates present (carina, rostrum, paired scuta, terga, upper latera, carinolatera, inframedian latera and rostrolatera); plates reduced in some taxa, lost in many Lepadoidea.
