Structure of the ovary in Nannochorista neotropica Navás (Insecta: Mecoptera: Nannochoristidae) with remarks on mecopteran phylogeny

Preliminary histological analysis showed that the ovaries in Nannochorista neotropica are composed of numerous ovarioles of panoistic type. In the ovaries of adult females each ovariole consists of a terminal filament, vitellarium and pedicle while a germarium is absent. Morphological observations supported by simple histochemical tests revealed the presence of multiple nucleoli in the oocyte nucleus. The appearance of multiple nucleoli suggests that the extrachromosomal amplification of ribosomal DNA may take place in the oocytes of Nannochorista. The results show that in the structure of the ovariole and the course of oogenesis nannochoristids share noteworthy derived features with boreids, but differ significantly from all other mecopterans. These findings indicate the possible monophyly of an assemblage comprising the Nannomecoptera, Neomecoptera and Siphonaptera.     

Fossils from the Middle Jurassic of China shed light on morphology of Choristopsychidae (Insecta,Mecoptera)

Choristopsychidae, established by Martynov in 1937 with a single isolated forewing, is a little known extinct family in Mecoptera. Since then, no new members of this enigmatic family have been described. Based on 23 well-preserved specimens with complete body and wings from the Middle Jurassic of northeastern China, we report one new genus and three new species of Choristopsychidae, two new species of the genus Choristopsyche Martynov, 1937: Choristopsyche perfecta sp. n. and Choristopsyche asticta sp. n.; one new species of Paristopsyche gen. n.: Paristopsyche angelineae sp. n.; and re-describe Choristopsyche tenuinervis Martynov, 1937. In addition, we emend the diagnoses of Choristopsychidae and Choristopsyche. Analyzing the forewing length/width ratios of representative species in Mecoptera, we confirm that choristopsychids have the lowest ratio of forewing length/width, meaning broadest forewings. These findings, the first fossil choristopsychids with well-preserved body structure and the first record of Choristopsychidae in China, shed light on the morphology of these taxa and broaden their distribution from Tajikistan to China, while increasing the diversity of Mesozoic Mecoptera in China.

刘氏蝎蛉卵巢管结构和卵子发生（英文）

卵巢管结构及卵子发生过程在探讨昆虫系统发育关系中有重要意义, 深入研究长翅目昆虫卵巢管结构及卵子发生可为确定其在全变态类昆虫中的系统发育地位提供依据。本文利用光学显微镜和扫描、透射电子显微镜技术研究了刘氏蝎蛉Panorpa liui Hua卵巢管超微结构及卵子发生过程。结果表明：蝎蛉卵巢由12根多滋式卵巢小管组成, 每个卵巢小管分为端丝、生殖区和生长区。根据滋养细胞、卵母细胞及滤泡细胞的变化, 卵子发生过程可分为5个阶段：卵黄发生前早期、卵黄发生前中期、卵黄发生前后期、卵黄发生期及卵壳形成期。在卵黄发生期, 滋养细胞为卵母细胞提供养分后逐渐消亡, 而此时的卵母细胞可通过滤泡之间的细胞间隙从血淋巴中获取营养。在卵壳形成期间, 3种不同类型的滤泡细胞参与形成不同区域的卵壳, 从而形成不同花饰的卵壳表面。据此推测, 与其他目的滋养细胞数目相比, 每个卵室中2次有丝分裂形成3个滋养细胞可能是比较原始的特征, 表明长翅目昆虫可能是全变态类群中近基部的分支。     

染翅蝎蛉Panorpa tincta Navas, 1931一新异名

蚊蝎蛉捕捉足构造

依据光学显微镜和扫描电镜观察,对扁蚊蝎蛉Bittacus planus Cheng和缠绕蚊蝎蛉Bittacus implicatus Huang et Hua成虫足的外部形态、肌肉组织及超微结构进行了描述和绘图。蚊蝎蛉成虫三对足结构相似,均为捕捉式,以高度特化的跗节捕捉猎物,各跗分节间具发达的关节、凹槽和爪缩肌肌腱膨大区,第4和5跗分节的齿形成嵌合构造,在昆虫纲中为该类群独有特征。首次发现胫节伸肌b由腿节基部发出的一小块三角形肌肉组织和一条长肌腱组成; 爪缩肌肌腱在第5跗分节凹槽末端有一突起,收缩时突起羁绊于凹槽内的“Y”字形底托。分析了成虫捕食行为与捕捉足构造之间的关系,并简要比较了蚊蝎蛉捕捉足与螳螂捕捉足的结构特点。
