Bioluminescence is a common feature of the communication and defence of marine organisms, but this phenomenon is highly restricted in the terrestrial biota. Here, we present a geographical distribution of only the third order of luminescent insects—luminescent cockroaches, with all 13 known and/or herein reported new living species (based on deposited(More)
The presence of bioluminescent system in cockroaches (Zompro and Fritzche 1999) and in Lucihormetica luckae in particular has been contested in reply by Merritt (2013), based on the absence of direct evidence of bioluminescence in the original article (Vršanský et al. 2012). Main counterarguments were based on (1) a single anec-dotal reference to the(More)
Viviparity evolved in bacteria, plants, ˃141 vertebrate lineages (ichthyosaurs, lizards, fishes, mammals, and others), and in 11 of 44 insect orders. Live-birth cockroaches preserved with brood sac (3D recovered two times optically) included Diploptera vladimir, Diploptera savba, Diploptera gemini spp.n., D. sp.1–2, and Stegoblatta irmgardgroehni from Green(More)
Dinosaurs undoubtedly produced huge quantities of excrements. But who cleaned up after them? Dung beetles and flies with rapid development were rare during most of the Mesozoic. Candidates for these duties are extinct cockroaches (Blattulidae), whose temporal range is associated with herbivorous dinosaurs. An opportunity to test this hypothesis arises from(More)
