Type species: Dilyta subclavata Förster, 1869 . Synonyms in Menke & Evenhuis (1991): 152.

Redescription. Length: 0.8–2.0 mm.

Head (fig. 1A): Rounded in anterior view, eyes located at middle line of head, malar space subequal to OOC. Surface completely smooth, without any strigae, malar impression, epistomal sulcus or clypeo-pleurostomal lines. Clypeus almost straight, slightly projecting over mandibles, without marginal inflection. Setae sparse, concentrated principally below toruli.

Antennae (fig. 3, 4): Size of pedicel and flagellomeres variable among species. Female: 13-segmented, slightly clavate; two last segments (F10–F11) broadly jointed. Male: 14-segmented, slightly clavate or filiform; two last segments (F11-F12) broadly jointed.

Mesosoma (fig. 1B): Pronotum with setae only in anterior part; pronotal carinae long, clearly indicated, going from scutum to anterior part of pronotum. Mesoscutum smooth, shining, almost without setae. Mesopleuron smooth, without any longitudinal ridge in lower part. Scutellum smooth with scarce setae at posterior and lateral parts. Propodeum with two strong and broad carinae. Apex of scutellum (fig. 2): HOLARCTIC SPECIES: with an ∩-shaped carina. AFROTROPICAL SPECIES: with one carina at each side, both symmetrical and parallel, distance between them equivalent to distance between propodeal carinae.

Forewing (fig. 1C): Large, longer than body, covered with dense pubescence; marginal setae present and long. Veins brown. Radial cell small and completely open along anterior margin; R1 very short, barely reaching costal margin; Rs short and almost straight, reaching wing margin; R1 and Rs not parallel; Cu1a, M+Cu1a, Rs+M and M veins absent.

Metasoma (fig. 5): T3 and T4 fused into one large syntergum. Proximal part with a complete ring of setae. Distal half with or without punctures.

Biology. When known, the species of this genus are hyperparasitoids of Psyllidae via Encyrtidae ( Hymenoptera : Chalcidoidea).

Distribution. Holarctic and Afrotropical regions.
