| 中文摘要: |
| 本研究采用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、微型计算机断层扫描（μCT）及三维重建技术，对车前长跗跳甲Longitarsus lewisii复眼的形态和超微结构进行了研究。车前长跗跳甲的复眼属于并列型，雄性平均有121.88 ± 7.64个小眼，雌性平均有119.00 ± 4.71个小眼。每个小眼由双凸角膜、由4个晶锥细胞组成的无晶晶锥、8个视网膜细胞及其感杆、2个初级色素细胞以及大量次级色素细胞组成。车前长跗跳甲的开放型感杆束由六个外周细胞网膜细胞（R1~R6）构成的外周感杆束和由R7和R8分别贡献的两个垂直排列的中央感杆束组成。微绒毛的排列方向表明其对偏振光的敏感性较弱。 |
| 英文摘要: |
| In this study, the morphology and ultrastructure of the compound eye of L. lewisii were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), micro-computed tomography (μCT), and 3D reconstruction. The compound eye of L. lewisii was of the apposition type, with an average of 121.88 ± 7.64 ommatidia in males and 119.00 ± 4.71 ommatidia in females. Each ommatidium was composed of a biconvex cornea, an acone consisting of four cone cells, eight retinular cells along with the rhabdom, two primary pigment cells, and numerous secondary pigment cells. The open type of rhabdom in L. lewisii consists of six peripheral rhabdomeres contributed by the six peripheral retinular cells (R1~R6) and two vertically attached central rhabdomeres contributed by R7 and R8 respectively. The orientation of microvilli suggested a weak sensitivity to polarized light perception. |
