Applying consistent terminology for morphological traits across different taxa is a highly pertinent task in the study of morphology and evolution. Different terminologies same can generate bias phylogeny prevent correct homology assessments. This situation exacerbated male genitalia Hymenoptera, specifically Ichneumonoidea, which not standardized has been fully aligned with rest Hymenoptera. In current contribution, we review terms used to describe skeletal features provide list authors associated previously terminology. We propose unified that be utilized order recommended terms. Further, discuss genital musculature superfamily Ichneumonoidea based on previous literature novel observations align muscles literature.

The male genitalia of insects are among the most variable, complex, and informative character systems for evolutionary analysis taxonomic purposes. Because these general properties, many generations systematists have struggled to develop a theory homology alignment parts.

Here, we take multimodal approach digitalize comprehensively document genital skeletomuscular anatomy bullet ant (Paraponera clavata; Hymenoptera: Formicidae), including hand dissection, synchrotron radiation microcomputed tomography, microphotography, scanning electron microscopy, confocal laser 3D-printing.

Abstract Insect legs play a crucial role in various modes of locomotion, including walking, jumping, swimming, and other forms movement. The flexibility their leg joints is critical enabling locomotion. frog‐legged leaf beetle Sagra femorata possesses remarkably enlarged hind legs, which are considered to be adaptation that enables the species withstand external pressures. When confronted with threats, S. initiates stress response by rapidly rotating its backward upward specific angle, thereby potentially intimidating potential assailants. Based on video analysis, we identified 4 distinct phases rotation process , were determined range angles (0°−168.77°). Utilizing micro‐computed tomography (micro‐CT) technology, performed 3‐dimensional (3D) reconstruction conducted relative positioning volumetric analysis metacoxa metatrochanter . Our revealed metacoxa–trochanter joint “screw‐nut” structure connected muscles, regulate legs. Further testing using 3D‐printed model demonstrated possession self‐locking mechanism capable securing positions prevent excessive dislocation. It can envisioned this holds for application bio‐inspired robotics.

Abstract In many extreme arid ecosystems, insects constitute major faunal components and are key contributors in nutrient cycling. Previous research on xerophily has focused adult forms. This study investigates skeletomuscular behavioural adaptations of the Kalahari sandworm beetle larvae ( Gonopus tibialis Fabricius) for dwelling sand. Microcomputed tomography enabled cuticle thickness distribution analysis, revealing structural reinforcements mandibular edge, middle part head, ventral side front legs. Laboratory observations analysis muscular system allowed definition functional description elements digging apparatus larvae. Obtained results point to crucial role head mandibles process.

Jumping is a rapid locomotory mode widespread in terrestrial organisms. However, it rare specialization ants. Forward jumping has been reported within four distantly related ant genera: Gigantiops, Harpegnathos, Myrmecia, and Odontomachus. The temporal engagement of legs/body parts during jump, however, varies across these genera. It unknown what morphological adaptations underlie such behaviors whether ants solely driven directly by muscle contraction or additionally relies on elastic recoil mechanism. We investigated the for behavior comparing differences musculature between non-jumping relatives using X-ray micro-CT 3D morphometrics. found that size-specific volumes trochanter depressor (scm6) middle hind legs are 3-5 times larger ants, one coxal remotor (scm2) reduced volume and/or legs. Notably, enlargement other groups linked to body engaged jump.
