The Upper Liassic Heteroptera of Mecklenburg and Saxony

Abstract

Abstract. Twenty‐seven species of Heteroptera from the Upper Liassic of Dobbertin, Mecklenburg, and East Lower Saxony are redescribed and reclassified as follows. PROGONOCIMICIDAE (= Actinoscytinidae and Eocimicidae): Progonocimex jurassicus, P.liasinus (= Eocimex liasinus ); Eocercopis ancyloptera, E.similis (= Cercoprisca similis ); Archicercopis falcata. ARCHEGOCIMICIDAE (= Eonabidae and Diatillidea): Archegocimex geinitzi, A.primitiva (= Eonabis primitiva), A.liadis (= Archegocoris liadis ); Somatocoris conservatus; Eurynotis incisus; Progonocoris pictus; Anosmus spilopterus; Entomecoris minor; Diatillus debilis; Corynecoris semigranulatus; Macropterocoris obtusus; Ensphingocoris praerotundatus. PACHYMERIDIIDAE (= Hypocimicidae, Sisyrocoridae and Psychrocoridae): Pachymeridium dubium; Sisyrocoris rudis; Hypocimex membranaceus; Apsicoria semideleta; Cathalus alutaceus; Psychrocoris cuneifera. CUNEOCORIDAE: Cuneocoris geinitzi. NAUCORIDAE (= Apopnidae and Aphlebocoridae): Apopnus magniclavus; Aphlebocoris punctata. Infraorder Gerromorpha incertae sedis: Engynabis tenuis. Progonocimicidae constitute the Infraorder Actinoscytinomorpha. Archegocimicidae, which have features recalling Pentatomomorpha, Cimicomorpha and Dipsocoromorpha, are left incerti infraordinis. Pachymeridiidae are probably Pentatomomorpha, and Cuneocoridae Dipsocoromorpha. The faunas therefore include representatives of four extant Infraorders, among them the earliest recorded Pentatomomorpha, Dipsocoromorpha and Gerromorpha.
