Lorryia Oudemans, 1925




  • The genus Lorryia was erected by Oudemans (1925) with L. superba as the type species.
  • The description of the genus took only one line: "Lorryia=Tydeus met ééne klauw aan elken poot !" which means "Lorryia=Tydeus with one claw to each leg". Oudemans (1928a: 229–232; 1928b: 380) confirmed that the genus Lorryia was unique in having only one claw whereas all the other related species had two claws.
  • The weak chaetotaxy of the palp is the second point of his concluding remarks (Oudemans, 1928a: 233) but was not retained in next publications.
  • Later, Oudemans changed his mind and concluded (1929: 481) "Op die gronden wensch ik de diagnose van het genus Lorryia te wijzingen als volgt : als Tydeus, maar dorsaal met geheel, of gedeeltelijk netvormige structuur". The translation is: "On this basis, I wish to modify the diagnosis of the genus Lorryia as follows: as Tydeus, but dorsally with entirely or partly reticulated pattern".
  • Thor (1933: 54) divided the genus Lorryia into two subgenera, Raphitydeus and Lorryia sensu stricto.
  • "The claw and palpal setal patterns are not typical for what we have assumed to be the genus. These must be misinterpretations." concluded (Baker, 1968: 986).
  • André (1980) observed that most Lorryia species had the same chaetotaxy as the genus Tydeus as it was defined by Baker (1965). Accordingly, he decided to transfer Baker’s Lorryia to Tydeus. There was, however, no formal synonymisation.
  • André (2005) proposed to restore the genus in its primitive state and it be monospecific. All other species assigned to Lorryia (Lorryia sensu Kaźmierski were transferred to Brachytydeus.
  • This was not accepted by Kaźmierski, see Kaźmierski et al. (2018: 804). As a result, the genus was interpreted in several ways and two synonymizations with the genus Brachytydeus followed (for further details, see André (2023).
  • André (2023), after a detailed study of the original description and in the absence of type, re-established again the genus in its primitive state, proposed it remains monospecific and redefined the genus Brachytydeus.
