Confocal and micro-CT data of Rhomeocalpsua torosa, holotype, NIGP180054

This dataset contains the raw confocal laser scanning microscopy (CLSM) slices and X-ray microtomography (micro-CT) slices for the holotype of <em>Rhomeocalpsua torosa</em> (NIGP180054) from mid-Cretaceous Burmese amber. This dataset is associated with the publication "<em>Rhomeocalpsua torosa</em> gen. et sp. nov., a unique lineage of Endomychidae from mid‑Cretaceous Burmese amber (Coleoptera: Coccinelloidea)" (DOI:10.11646/palaeoentomology.5.2.7). Confocal images were obtained with a Zeiss LSM710 confocal laser scanning microscope, using the 488 nm (Argon) or 566 nm (DPSS 561-10) laser excitation lines. The original CZI files are provided, which could be opened by the ZEISS ZEN software. Micro-CT data were obtained with a Zeiss Xradia 520 Versa 3D X-ray microscope. Scanning parameters were as follows: isotropic voxel size, 1.9324 μm; power, 4 W; acceleration voltage, 50 kV; exposure time, 1.5 s; projections, 3001. The TIFF stack is provided.本数据集包含产自白垩纪中期缅甸琥珀的*Rhomeocalpsua torosa*正模标本（holotype，编号NIGP180054）的原始共聚焦激光扫描显微镜（Confocal Laser Scanning Microscopy, CLSM）切片与X射线显微断层扫描（X-ray microtomography, micro-CT）切片。本数据集配套发表于论文《*Rhomeocalpsua torosa* 新属新种（gen. et sp. nov.）：产自白垩纪中期缅甸琥珀的大蕈甲科独特演化支（鞘翅目：瓢甲总科）》（DOI: 10.11646/palaeoentomology.5.2.7）的研究成果。共聚焦成像采用蔡司LSM710共聚焦激光扫描显微镜完成，使用488 nm（氩离子）或566 nm（DPSS 561-10）激光激发光路。原始CZI文件已提供，可通过蔡司ZEN软件打开。X射线显微断层扫描数据使用蔡司Xradia 520 Versa 3D X射线显微镜获取，扫描参数如下：各向同性体素尺寸1.9324 μm；功率4 W；加速电压50 kV；曝光时间1.5 s；投影数3001。已提供TIFF格式图像序列栈。
