No full textFig. 4 in Comparative Morphology of the Orthopteran Thorax With a Discussion of Phylogenetically Relevant Characters
Full text linkFig. 4. Morphology of mesospina in representatives of Ensifera (A–L) and Caelifera (M). (A–D) Volume rendering. (E–M) 3D reconstruction. Orthoptera bear a stalked mesospina (green asterisk).The vast majority of Ensifera is characterized by a mesospina that bears paired dorsolateral* and ventrolateral processi, only Comicus calcaris has a single lateral process (F). Whereas the dorsolateral processus* is tapered in most Ensifera, the dorsolateral process* in Gryllus bimaculatus is knob-like (E). Some taxa have an unpaired posterior process, marked by pink asterisk.The mesospina of Stenobothrus lineatus is characterized by a distal plate that lacks processi. st2 (mesosternum), st3 (metasternum).Published as part of Fanny Leubner, Benjamin Wipfler & Sven Bradler, 2017, Comparative Morphology of the Orthopteran Thorax With a Discussion of Phylogenetically Relevant Characters, pp. 29-47 in Insect Systematics and Diversity 1 (1) on page 37, DOI: 10.1093/isd/ixx006, http://zenodo.org/record/103709
Cephalic morphology of Hymenopus coronatus (Insecta: Mantodea) and its phylogenetic implications
No full textExternal and internal head structures of the mantodean Hymenopus coronatus are examined and described in detail. The results are elaborately compared with the literature. Strong crests on the anterior tentorial arms that articulate with the subantennal suture, a parietal suture and glossae and paraglossae with anteriorly bent tips are proposed as new potential apomorphies for Mantodea while a head capsule being wider than long, enlarged compound eyes, the presence of a frontal shield or scutellum, lateral lobes in the anterior tentorial arms, the presence of a transverse and an interantennal suture and the reduction of the mentum are confirmed as apomorphies, As potential apomorphies for Dictyoptera the reduction of Musculus tentoriobuccalis lateralis (M. 49) is newly presented and a "perforate" tentorium, lacinial incisivi that are located in a galeal pouch and the presence of a postmola are confirmed. The present study shows the value of cephalic morphology for phylogenetic analysis but also points out that further studies including evolutionary key taxa are essential for resolving the evolutionary adaptations among dictyopterans.

The thorax of Mantophasmatodea, the morphology of flightlessness, and the evolution of the neopteran insects
No full textMantophasmatodea was described as a new insect order in 2002. Since then, this small group of wingless insects has developed into one of the best investigated insect taxa. Nevertheless, many aspects of mantophasmatodean morphology as well as their evolutionary relationships remain ambiguous. To determine the phylogenetic relationships of Mantophasmatodea based on an extended character set and to elucidate possible morphological adaptions towards flightlessness, we investigated the thoracic morphology of two species, Austrophasma caledonensis and Mantophasma sp. The morphological similarity between these two species is striking and no differences in musculature were found. The mantophasmatodean thorax strongly resembles that of ice crawlers (Grylloblattodea), especially with respect to the presence of pleural processes in the meso- and metathorax, branched furcae in all segments, and similar muscle equipment. In a cladistic analysis containing all major lineages of Neoptera, the monophyly of Polyneoptera is supported by the presence of an anal fan and several modifications of the wing joint. Within Polyneoptera, a sister-group relationship between stoneflies and the remaining Polyneoptera is supported. A clade comprising Mantophasmatodea and the Grylloblattodea gains strong support from thoracic morphology and can be considered assured. Potential thoracic apomorphies include prothoracic paracoxal invaginations, pterothoracic pleural arms that originate from the epimeron, and a unique metathoracic sterno-coxal musculature. The monophyly of Orthoptera and Dictyoptera is further supported while the deeper polyneopteran nodes remain unresolved. Among the wingless taxa investigated we found few general morphological adaptations whereas, in other aspects, especially in the musculature, strong differences could be observed. However, much more research on the strongly neglected topic of flightlessness is required to make reliable statements. (C) The Willi Hennig Society 2014
