Abstract
Abstract Mid-Cretaceous amber from Myanmar, also known as “burmite”, has produced 1013 species of which 693 are Insects. The Mesozoic cockroach record is rich, with thousands of specimens that show diverse ecological adaptations. Cretaceous cockroaches in amber have been reported from Lebanon, Taimyr, New Jersey and France. Cockroaches from Myanmar amber are represented by at least 74 species, of which 14 are formally described. Spinaeblattina with S. myanmarensis gen. et sp. nov. and S. yixianensis comb. n. =  Piniblattella yixianensis from the Yixian Formation is along with Cratovitisma the second genus of the Mesoblattinidae known from both amber and sedimentary deposits. Fossil ootheca are rare with 6 specimens reported so far and the present isolated one, Blattoothecichnus argenteus ichnogen. et ichnosp. nov., is the most ancient, portable, otherwise resembling that of Cryptocercus . Ancient crystals of organic salt, calcium oxalate, forming the ootheca protective layer have been preserved on its surface.

Abstract Among insects, 236 families in 18 of 44 orders independently invaded water. We report living amphibiotic cockroaches from tropical streams of UNESCO BR Sumaco, Ecuador. We also describe the first fossil aquatic roach larvae (6 spp.; n = 44, 1, 1, 1, 1, 1) from the most diverse tropical Mesozoic sediments (Middle Jurassic Bakhar Fm in Mongolia, Kimmeridgian Karabastau Fm in Kazakhstan; Aptian Crato Fm in Brazil), and the Barremian Lebanese and Cenomanian Myanmar ambers. Tropic-limited oc...

Abstract A new corydiid cockroach, Magniocula apiculata gen. et sp. nov., is described and illustrated based on a well-preserved specimen in Upper Cretaceous Burmese amber. Magniocula is placed in the extant subfamily Euthyrrhaphinae based on the small pubescent body, large clypeus surpassing the distal border of the antennal sockets, and two spines at apex of the front femur. However, this new genus is unique among Euthyrrhaphinae for its holoptic eyes. This is the second corydiid species found...

Alienoptera have been recently described from mid-Cretaceous amber and are nested phylogenetically inside the Dictyoptera lineage as the sister group of Mantodea. The second known species, Alienopterella stigmatica gen. et sp. nov., is described and illustrated in this contribution based on a male embedded in Cretaceous Burmese amber of earliest Cenomanian age. The well-preserved holotype allows clarification of the characteristics of the order. The first-studied hind wings are derived from the ...

Most cockroaches produce a special capsular structure, the ootheca, to enclose eggs for protection and maternal brood care. However, the origin and early evolution of the cockroach ootheca is poorly known, attributable to a lack of fossil evidence from the Mesozoic. Here, we report the earliest known cockroach fossil possessing an internally partitioned ootheca: Piniblattella yixianensis Gao, Shih & Ren sp. nov. is described from the mid Early Cretaceous Yixian Formation of China. The ootheca of...

Myrmecophilous and termitophilous interactions likely contributed to the competitive advantage and evolutionary success of eusocial insects, but how these commensal and parasitic relationships originated is unclear due to absence of fossil records. New extinct cockroaches of the still living family Blattidae are reported here from the Cretaceous Myanmar amber (99 Ma) and are the earliest known inhabitants of complex ant nests, demonstrating that this specialised myrmecophily originated shortly a...

Abstract Here we describe a new corydiid cockroach, Nodosigalea burmanica gen. et sp. nov., from the middle Cretaceous Burmese amber. The well-preserved specimens exhibit a typical habitus of Corydiidae, and are characterized by nodulous pronotum, distinct wing venation and unique tarsi, the hind ones of which have different ventral structures from the fore- and midlegs. The combination of adhesive fore- and midtarsi and propulsive hindtarsi suggests a particular life style of the new genus. The...

Batesian mimicry is a relationship in which a harmful organism (the model) is mimicked by a harmless organism (the mimic), which gains protection because predators mistake it for the model. It is the most widely studied of mimicry complexes and has undoubtedly played an important role in the speciation of various animals especially insects. However, little is known about the early evolution of this important behavior and its evolutionary significance owing to a dearth of paleontological records....

Summary Alienoptera is an insect order recently described from mid-Cretaceous amber [1] and is phylogenetically nested in the Dictyoptera lineage. Alienoptera currently comprises three species: Alienopterus brachyelytrus [1] , Alienopterella stigmatica [2] and Caputoraptor elegans [3] . The most interesting is Caputoraptor elegans, which was recently described in Current Biology by Bai and colleagues [3] and which has an unusual cephalo-thoracic device formed by wing-like extensions of the genae...

AbstractBurmese amber is an extremely important source of mid-Cretaceous plant and animal remains with over 870 species of organisms, ranging from protozoa to vertebrates, described from this source. The amber mines are located on the West Burma Block that according to geologists was originally part of Gondwana. The present study introduces some angiosperms and insects in Burmese amber whose closest extant relatives have a Gondwanan distribution and there is no previous evidence of a Laurasian d...

Summary Insects use different parts of their body to cling to mating partners, to catch prey, or to defend themselves, in most cases the mouthparts or the legs. However, in 400 million years of evolution [1, 2], specialized devices were independently acquired in several groups to adopt these tasks, as for instance modified legs in mantids, assassin bugs or stick insects [3–5], or clasping antennae of the globular springtails [6]. So far, no known species used the neck region between the head and...

Abstract The Blattulidae is an extinct family of cosmopolitan Mesozoic cockroaches with a low generic diversity. Habroblattula laiyangensis sp. nov. from the Lower Cretaceous Laiyang Formation of Shandong Province of China with well-preserved both hind wings is only closely related to the H. drepanoides Wang, Liang & Ren, 2007 from the Early Cretaceous Yixian Formation, sharing the venation pattern, while being significantly smaller, and provides new characteristics of ancient Blattulidae. In ad...

Morphological insect-insect mimicry is known from few Cretaceous cockroaches and a beetle. Formicamendax vrsanskyi gen. et sp. n. (Blattaria, Alienopteridae) shows myrmecomorph features such as an elongated, smooth and black body, simple fenestrated hindwing, legs lacking protective spines. Elbowed or “geniculate “antenna is a typical character of advanced ants and weevils used for different forms of communication. Together with reduced mouthparts and specialized palps still preserved grasping f...
