Genus Lobotractus Grishin, 2019

Type species: Eudamus valeriana Plötz, 1881 .

ZooBank registration: C6E5B5DF-1C74-4DBD-85C3-7285209F6F03

Diagnosis: The genus was defined as a clade from about 15 Mya that contains the species Eudamus valeriana Plötz, 1881 , and putatively synapomorphic DNA characters for this clade were given ( Li et al., 2019). Phenotypically, diagnosis for this genus is the same as given for the "cyda group" by Burns (1996: 196). The following combination of characters unifies all known species in the genus and distinguishes them from all other genera: 3rd segment of palpi long, longer than in Codatractus ( Fig. 18 ); costal fold absent; uncus undivided, in dorsal view longer than wide and slightly concave terminally and on the sides ("scalloped" per Evans (1952)), but not prominently bilobed; tegumen humped in lateral view; shorter, fan-like cornutus with many sharp branches; valvae with a fang-like harpe bending dorsad and enlarged, rounded ampulla protruding caudad to reach the end of harpe; lamella antevaginalis expanded in two large plates, each on the side of ostium bursae, plates reach the end of lamella postvaginalis and protrude further narrowing towards the middle into a sharp tooth, plates fully separated mid-ventrad exposing ostium bursae ventrally. All these characters are illustrated in Burns (1996), who discovered them and described in detail.

Species included: Eudamus valeriana Plötz, 1881 , Thorybes uvydixa Dyar, 1914 , and Heteropia cyda Godman, 1901 .

Parent Taxon: Subtribe Loboclina Grishin, 2019 .
