Revision of the Antillocaprinidae Mac Gillavry (Hippuritida,Bivalvia) and their position within the Caprinoidea d’Orbigny

The rudist bivalve family Antillocaprinidae Mac Gillavry is revised following a study of nearly all available material in museum collections. Based on differences in their myocardinal arrangements, three subfamilies are recognized: the Titanosarcolitinae nov. subfam., the Antillocaprininae Mac Gillavry, and the Parasarcolitinae nov. subfam. Fifteen genera are described, of which ten are new: Eosarcolites nov. gen., Caenosarcolites nov. gen., Clinocaprina nov. gen., Rotacaprina nov. gen., Rudicaprina nov. gen., Stellacaprina nov. gen., Oligosarcolites nov. gen., Polysarcolites nov. gen., Alencasteria nov. gen., and Sawkinsonia nov. gen. Genera, which are placed in monophyletic radiations, are differentiated on minor differences in myocardinal arrangements, morphotype, and presence or absence of tubes. Six new species are described: Eosarcolites radiatus nov. gen., nov. sp., Caenosarcolites scholaris nov. gen., nov. sp., Rudicaprina planus nov. gen., nov. sp., Sawkinsonia maldonensis nov. gen., nov. sp., Alencasteria macrotubularis nov. gen., nov. sp., and Stellacaprina gunteri nov. gen., nov. sp. Cladistic analysis was performed on selected genera from the Caprinoidea, justifing the division of the Antillocaprinidae into three subfamilies, although extensive paraphyletic groupings exist in the lower part of the strict consensus tree. Weighting myocardinal characters produces a strict consensus tree largely consistent with current subfamily- and family-rank taxonomy, and is consistent with the order of appearance of taxa in the fossil record. The Antillocaprinidae show a major evolutionary radiation reaching a first peak in the middle Campanian, a decline in the late Campanian, and a second peak just before the rudist extinction at the end of the Cretaceous.

A Remarkable New Family of Jurassic Insects (Neuroptera) with Primitive Wing Venation and Its Phylogenetic Position in Neuropterida

Background

Lacewings (insect order Neuroptera), known in the fossil record since the Early Permian, were most diverse in the Mesozoic. A dramatic variety of forms ranged in that time from large butterfly-like Kalligrammatidae to minute two-winged Dipteromantispidae.

Principal Findings

We describe the intriguing new neuropteran family Parakseneuridae fam. nov. with three new genera and 15 new species from the Middle Jurassic of Daohugou (Inner Mongolia, China) and the Early/Middle Jurassic of Sai-Sagul (Kyrgyzstan): Parakseneura undula gen. et sp. nov., P. albomacula gen. et sp. nov., P. curvivenis gen. et sp. nov., P. nigromacula gen. et sp. nov., P. nigrolinea gen. et sp. nov., P. albadelta gen. et sp. nov., P. cavomaculata gen. et sp. nov., P. inflata gen. et sp. nov., P. metallica gen. et sp. nov., P. emarginata gen. et sp. nov., P. directa gen. et sp. nov., Pseudorapisma jurassicum gen. et sp. nov., P. angustipenne gen. et sp. nov., P. maculatum gen. et sp. nov. (Daohugou); Shuraboneura ovata gen. et sp. nov. (Sai-Sagul). The family comprises large neuropterans with most primitive wing venation in the order indicated by the presence of ScA and AA1+2, and the dichotomous branching of MP, CuA, CuP, AA3+4, AP1+2. The phylogenetic position of Parakseneuridae was investigated using a phylogenetic analysis of morphological scoring for 33 families of extinct and extant Neuropterida combined with DNA sequence data for representatives of all extant families. Parakseneuridae were recovered in a clade with Osmylopsychopidae, Prohemerobiidae, and Ithonidae.

Conclusions/Significance

The presence of the presumed AA1+2 in wings of Parakseneuridae is a unique plesiomorphic condition hitherto unknown in Neuropterida, the clade comprising Neuroptera, Megaloptera, Raphidioptera. The relative uncertainty of phylogenetic position of Parakseneuridae and the majority of other families of Neuroptera reflects deficient paleontological data, especially from critical important periods for the order, earliest Triassic and latest Triassic/earliest Jurassic.
