Enaesius Enock, 1909: 456 . Type species: Enaesius agilis Enock, 1909 , by subsequent designation by Gahan & Fagan, 1923: 50 . Synonymy by Debauche. 1948: 192. Anthemiella Girault, 1911 [90]: 185. Type species: Anthemiella rex Girault, 1911 , by original designation. Synonymy by Schauff, 1984a: 45 ; previous synonymy under Parallelaptera by Girault, 1912 [112]: 297. Erythmelus ( Erythmelellus ) Viggiani & Jesu, 1985: 487 . Type species: Erythmelus lygivorus Viggiani & Jesu, 1985 , by original designation. Diagnosis . Body length 370–1590 μm; 330–1170 in Triapitsyn et al . (2007). Head in lateral view with gena short ( Fig. 396 ) or absent ( Figs 388 , 389 , 403 ) so head appearing thin and long; mandible (in both sexes) reduced to small stub, without teeth ( Fig. 406 ); maxillae together in posterior view distinctly longer than wide ( Figs 402 ); mesosoma in lateral view with dorsellum slightly overhanging propodeum ( Figs 396 , 408 ); propodeum medially divided by a longitudinal sulcus ( Fig. 395 , 407 ); gaster in lateral view with hypopygium long, extending posteriorly at least to apex of gaster ( Figs 388 , 389 , 398 , 413 ). Discussion . Schauff (1984) related Erythmelus to Anaphes , based on the propodeum with a median longitudinal sulcus, but otherwise the two genera are structurally very different. Nearctic hosts . Hemiptera : Miridae , Tingidae . Important reference . Triapitsyn et al . (2007).
