The Orthoptera (Ensifera) from the Santana formation (Early Cretaceous, Northeast Brazil): A statistical and paleoecological approach, with description of new taxa

Abstract

This paper on the Araripe orthopterofauna reviews the Cearagryllus-like Grylloidea (Orthoptera: Ensifera) from the laminated limestone of the uppermost part of the Crato Member, lowest unit of the Santana Formation (Early Cretaceous), Araripe Basin, near Santana do Cariri and Nova Olinda municipalities (Ceará State, Northeast Brazil). The following new taxa are proposed: Notocearagryllus arturandradai n. sp., Cryptocearagryllus revelatus n. gen. et n. comb., Allocearagryllus leipnitzi n. gen et n. comb., Cearagrylloides perforatorius n. gen. et n. comb., Cearagrylloides microcephalus n. gen. et n. comb., Cearagrylloides previstus n. gen. et n. comb., and Paracearagryllus poliacanthus n. gen. et n. comb. (Cearagryllinae n. subfam.). Additionally new data on the paleoecology and paleoethology are furnished as well as a statistical approach.

On the placement of the Cretaceous orthopteran Brauckmannia groeningae from Brazil, with notes on the relationships of Schizodactylidae (Orthoptera, Ensifera)

“…This collection was apparently stored at his home in Ribeirão Preto, São Paulo, though since his death in August 2010 its whereabouts are unknown. As a result, any discussion of the holotype presented herein is based entirely on the illustrations in the original description ( Martins-Neto 2007 ). However, we were recently able to examine a second, more completely preserved specimen in the Museum für Naturkunde, Berlin, Germany (MfNB).…”

“… Orthoptera (crickets, katydids, grasshoppers and their kin) are well-represented in the Crato Formation ( Heads and Martins-Neto 2007 ) and constitute the most frequently encountered insect fossils in the Nova Olinda laminites. Both orthopteran suborders are present, including a diverse assemblage of Ensifera comprising the superfamilies Grylloidea , “ Hagloidea ” and Stenopelmatoidea sensu lato ( Martins-Neto 1991 , 2007 ; Heads and Martins-Neto 2007 ). Caelifera are represented by primitive Tridactyloidea , Eumastacoidea and stem-acridomorphs of the paraphyletic ‘locustopsoid’ complex ( Martins-Neto 2003 ; Heads 2008 ).…”

“…The unusual orthopteran Brauckmannia groeningae was described by Martins-Neto (2007 : 3–4, fig. 1) based on a single specimen from a large quarry complex to the northeast of Mina Pedra Branca, 4–5 km west of Nova Olinda on the northern flanks of the Chapada do Araripe (see Martill et al 2007 for locality details).…”

“…1) based on a single specimen from a large quarry complex to the northeast of Mina Pedra Branca, 4–5 km west of Nova Olinda on the northern flanks of the Chapada do Araripe (see Martill et al 2007 for locality details). Martins-Neto (2007) assigned the genus to its own family, Brauckmanniidae , which he assigned to the superfamily Stenopelmatoidea sensu lato ; a group comprising the Anostostomatidae (king crickets and wetas), Cooloolidae (Cooloola monsters), Gryllacrididae (leaf-rolling or raspy crickets) and Stenopelmatidae (Jerusalem crickets). However, Martins-Neto’s original description (2007) is cursory at best and suffers from numerous errors in the identification and interpretation of morphological structures critical to the proper placement of the fossil.…”
