Diagnosis

Adults. In his search for the true Tydeus , in the Oudemans Collection, André (2005) designated new type species for Tydeus , established that Lorryia is actually a monotypic genus based on unique characters and that Brachytydeus is a valid genus. All the species assigned to the genus Lorryia by Kaźmierski (1989, 1996) display the same chaetotaxy as Tydeus cruciatus which was designated as the type species of Brachytydeus . This genus is defined as follows: opisthosoma with 10 pairs of setae (ps included); poriodotaxy: three (im sometimes posterior to setae e 1); genital organotaxy—adults: no eugenital setae in female but male has four pairs, six pairs of genital setae are present and four pairs of aggenital setae in both adults; coxa I with coxal organ; chaetotaxy of leg segments: 8(ω)-6(ω)-5-5, tibiae 3 + k -2-2-2, genua 3-2-1-1, femora 3-3-2-1, trochantera 1- 0-1-0, epimeral formula adults: 3-1-4-2; solenidiotaxy: two; femur IV entire; palp chaetotaxy: 6(ω)-2-2.
