Fig. 8

Postlarval instar 2 of Pallenospis vanhoeffeni. SEM micrographs (B–E, G, H) and stereomicroscopic images of Sytox-stained specimens (A, A’,F). A Ventral view. Arrowheads indicate ventral intersegmental folds. The arrow points at the slit-shaped proctodeum anlage. A’ Detail of the pointed ocular tubercle. Arrows indicate the pair of anterior eyes. B Ventral view. Arrowheads indicate ventral intersegmental folds. Note the distinct dorso-distal seta on the future tibia 1 of walking leg 3 (arrow). C Anterior body pole. Lateral view. Arrowheads mark setae on the distal end of the scape. The stippled circle highlights the short attachment gland process. Arrows point at lateral setae on the chela palm. D Detail of the left chela. Arrowheads indicate characteristic setae at the base of the moveable and immovable chela fingers. E Detail of the attachment gland process. Note fibrous secretion emanating from the process of this specimen. F Detail of proboscis and larval limbs. Ventral view. Arrowheads point at the cuticular husks of the larval limbs, whereas the stippled lines indicate the extension of the remaining limb tissue. G Detail of the larval limbs. Note distinct external subdivision into three articles (1–3). Arrows point at the lateral seta of each proximal article. The arrowheads indicate the medial seta on each second article. H Details of bi-, tri- and tetrafurcating “Gabelborsten”. The arrow marks a slit-organ. Abbreviations: ch – cheliphore; chp – chela palm; ff – fixed chela finger; mf – moveable chela finger; ot – ocular tubercle; ovl – ovigeral larval limb; pal – palpal larval limb; pr – proboscis; sc – scape; wl – walking leg
