Figs 2–3 , fig. 150 in Jaschhof & Jaschhof (2013) This new species was erroneously referred to as A. baltica Spungis in our revision of Swedish Porricondylinae ( Jaschhof & Jaschhof 2013 : 314f. ), where we described it on the basis of three males from Uppland. As these are the only specimens known of this species, they are designated here as the types of A. rickebasta . While the species description published in 2013 is fully applicable to A. rickebasta , an updated diagnosis is presented here taking A. baltica and A. taigensis sp. nov. , two species resembling A. rickebasta , into account. Diagnosis. The ventral parameres of A. rickebasta are unique in forming a triangle-shape with a somewhat raised, longitudinal axis, which appears as an unsharp dark line in slide preparations ( Fig. 3 , ↓ 2 ). A pair of membranous, faintly contoured lobes basally of this triangle is also believed to be of parameral origin ( Fig. 3 ). The helmetshaped gonostylus is slightly swollen below the apical claw, which consists of numerous spines forming a broad comb ( Fig. 2 , ↓ 1 ). The gonostylus of A. baltica is similar, except that the apex is narrower and the apical claw, which actually is a solid tooth, is smaller ( Fig. 18 , ↓ 1 ). The gonostylar structure in A. taigensis is unmistakable in that the area below the claw is strongly swollen, with the result that the claw, a comb of rather small size, is in a subapical position ( Fig. 4 , ↓ 3 ). The parameres of A. baltica ( Figs 18–19 ) and A. taigensis ( Fig. 4 , ↓ 4 ) are quite unlike that found in A. rickebasta , which provides another effective distinction. Etymology. The species name, a noun in apposition, refers to the type locality, Rickebasta Nature Reserve in Sweden’s province Uppland. Type material. Holotype .
