Lorryia Oudemans, 1925


  • Feminine

Type species[edit]


  • 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.
  • 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.
  • 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 synonymize Lorryia with Tydeus.
  • Currently, the genus Lorryia is interpreted in two ways.
    • First interpretation (based on the single claw)
      • Interpretation proposed or followed by Oudemans (1925, 1928), André (2005: 981–982), Kaźmierski (2009), and the world catalogue of Silva et al. (2016: 29),
      • The genus includes only one species,
      • Lorryia and Brachytydeus are two distinct genera.
    • Second interpretation (based on the reticulation)
      • Interpretation proposed or followed by Oudemans (1929), Thor (1933: 53), Baker (1944, 1965, 1968), Kaźmierski (1998), and Mondin et al. (2016).
      • The genus includes > 200 species,
      • Brachytydeus is considered a junior synonym of Lorryia.
  • This database follows the first interpretation (except for recent species placed between square brackets).
