  An Overlooked Species of Enigmatic Wolf Spider (Araneae: Lycosidae) Clarifies the Mysterious Distribution of its Sibling Abstract Several wolf spiders exhibit a peculiar geographical distribution. One good example of this is Pardosa aenigmatica Tongiorgi, 1966, recently recognized in Italy and the Middle East but missing in the Balkans. A comparison of populations from the disjunctive areas revealed that they would be better described as two distinct species. As a result, here we describe Pardosa sepidehae sp. nov. The paper includes detailed descriptions and comparative illustrations of male and female copulatory organs for the newly discovered species and P. aenigmatica. Pardosa sepidehae sp. nov. is distributed in the Middle East, whereas P. aenigmatica remains endemic to the Apennine Peninsula.

Fusion of Pectinal Teeth in Scorpio kruglovi Birula, 1910 (Scorpiones: Scorpionidae)

Abstract


A rare teratological anomaly of pecten is described and illustrated: a case of fusion in pectinal teeth in the scorpion Scorpio kruglovi Birula, 1910). It was observed that 7th and 8th teeth are fused in the right pecten. The resulting fused tooth is larger than other teeth. A smaller fulcrum located inside of the large, fused tooth whereas other fulcra are located between normally developed teeth.
