Abstract

The morphological ontogeny of Pilogalumna tenuiclava (Berlese, 1908) is redescribed and illustrated. The prodorsal setae of juveniles are of medium size or long and barbed, and bothridial seta is fusiform, with thick, barbed head. Larva has 11 pairs of gastronotal setae, including h2, most are short and smooth, except for longer and barbed c2, c3, dp, h1 and h2. The nymphs have 15 pairs of these setae, most are short and smooth, except for longer and barbed c3. Gastronotal shield of juveniles is poorly developed, with setae of d-, l-series, and h1 in the larva, and d-, l-, h-series and p1 in the nymphs, setae of c-series, p2 and p3 are inserted on unsclerotized integument. In all juveniles, a humeral organ is present.

摘要

纤弱毕氏胸刺螨（Berlese，1908）的形态发生学被重新描述并图示。幼螨的前背板刚毛中等大小或较长且具刺，两叉毛刚毛呈梭形，头部粗且具刺。幼虫有 11 对腹侧板刚毛，包括 h2，大多数是短而光滑的，除了较长且具刺的 c2、c3、dp、h1 和 h2。若虫有 15 对这些刚毛，大多数是短而光滑的，除了较长且具刺的 c3。幼螨的腹侧板发育不良，幼虫有 d-、l-系列和 h1 刚毛，若虫有 d-、l-、h-系列和 p1 刚毛，c-系列、p2 和 p3 刚毛插入未骨化的表皮。在所有幼螨中都存在肩突器。
