New Ichneumonidae (Hymenoptera) from the Upper Cretaceous ambers of the Taimyr Peninsula

Two new genera and four new species of Ichneumonidae are described from the Upper Cretaceous ambers of the Taimyr Peninsula: Agapia sukatchevae gen. et sp. nov., Agapteron popovi gen. et sp. nov., Eubaeus abdominalis sp. nov., and Urotryphon baikurensis sp. nov. New detailed diagnoses are provided for the genera Urotryphon and Eubaeus. The genera Catachora, Urotryphon, and Eubaeus, previously placed in the subfamily Tryphoninae, are transferred to the subfamily Labenopimplinae, as well as the new genera Agapia and Agapteron. Possible causes of the miniaturization in ichneumonid wasps in the Cretaceous are discussed.     

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.     

New bugs of the family Archegocimicidae (Hemiptera: Heteroptera) from the Upper Jurassic of Mongolia

Taxonomy and molecular phylogeny of three freshwater scuticociliates,with descriptions of one new genus and two new species (Protista,Ciliophora, Oligohymenophorea)

Three freshwater scuticociliates, Apouronema harbinensis gen. nov. spec. nov., Cyclidium vorax spec. nov., and C. glaucoma Müller, 1773, collected from rivers in Hulan District, Harbin, northeastern China, were investigated using morphological and phylogenetic criteria. Apouronema gen. nov., assigned to the family Uronematidae, is mainly distinguished from the other genera of the family by its paroral membrane extending anteriorly to the middle of membranelle 1. Apouronema harbinensis spec. nov. is defined by body size in vivo about 45–55 × 20–25 μm, buccal field about 70–80% of cell length; 12 or 13 somatic kineties; membranelle 1 having two rows, with 16–18 basal bodies in each kinety; membranelle 2 and membranelle 3 both having two rows each; scutica X-shaped with five pairs of basal bodies. Cyclidium vorax spec. nov. is characterized by the following features: body size 35–40 × 18–20 μm in vivo; 9 or 10 somatic kineties; membranelle 1 having two longitudinal rows, much shorter than M2; M2 triangle-shaped. The phylogenetic analyses show that: (1) Apouronema clustered in the Uronematidae clade, and grouped with genera Uronemita and Uronema; (2) Cyclidium vorax spec. nov. grouped with C. glaucoma and C. sinicum, which supports the assignment of the new species to the genus Cyclidium; (3) Cyclidium remains non-monophyletic with the addition of the new sequence.

Drei neue moosbewohnende Ascomyceten

The following three species of parastiticascomycetes are described, illustrated and discussed in detail:Octosporella ptilidii spec. nova (Pezizales) onPtilidium ciliare from Switzerland,Nectria mnii spec. nova (Hypocreales) onPlagiomnium medium from Switzerland, andPhilobryon anuliferum gen. et spec. nov.
