RESULTS AND CONCLUSIONS The body of Aculus schlechtendali is elongate and fusiform. Its colour is opal paleyellow. The trunk is evenly and mildly arched. The prosoma and the opisthosoma are fused, their connection is indistinct on the ventral side, but the outline of the prodorsum is well separated on the dorsal side (Fig. 1). Notogaster widest behind the prodorsum and gradually becoming narrower towards the end of the body. Prodorsum is approximately triangular, its breadth is decreasing forward and ending in a frontal extension (Fig. 2). Surface with a characteristic pattern of two, slightly directed asunder and some unimportant lines towards the notogaster. The two, prodorsal hairs are directed apart and backwards. Their basal warts are situated in front of the backline of the prodorsum (Fig. 2). The rings of the notogaster are not uniform, because one part of the rings is fused on the dorsal side creating wider tergites. So the number of the ventrites is about 1.5 times more than that of the tergites. The width of the tergites is mostly uniform excepting the last one. Latter consisting of two, semicircular sheets, the tail-setae are on its upper part and the anus is on its bottom (Fig. 1). A thin, chitin layer covers the notogaster. The tergites do not form a backbone, their edges are not saw-like, neither at the top nor in the side view (Fig. 1 and 2). The rostrum is short and directed downwards. The palpus cornprinting four joints below the rostrum. The two pairs of legs of Aculus schlechtendali are powerful, located on the ventral side of the prosoma. That is why the long-drawn notogaster is only proped up by the three pairs of ventral setae and the last sheet (Fig. 1). The legs comprises six joints. There are two claws, a comb-like and a simple one on the end of the tarsus, and above these, two tarsal solenidia are directed forward and asunder. The tibia is hairless, its length corresponds the tarsus. Gena with solenidia pointing forward (one on each). These are two times longer on the first pair of legs than on the second. There is one femoral solenidion on a well-developed wart on the upper third of the femur Figure 1. Deutogyn female of Aculus schlechtendali in side-view Folia ent. hung. 59, 1998
