( Figs. 25–33 )

Cheiloneurus n. sp. near amplicornis Gahan : Noyes & Triapitsyn 2018: 21 (mentioned as a hyperparasitoid from Barbados).

Material Examined. BARBADOS, Christ Church Parish, Rockley , 8 Sep 2009, M. A. Ciomperlik (from Hypogeococcus sp. ) [4 females, 4 males, BMNH] .

Host. Hyperparasitoid of the Harrisia cactus mealybug, Hypogeococcus sp. , in Barbados via Leptomastidea hypogeococci [as Leptomastidea sp. ] ( Noyes & Triapitsyn 2018).

Comments. This species is quite likely not conspecific to any of the known species of Cheiloneurus Westwood from the New World although it is somewhat similar to Ch. banksi (Howard) , of which Ch. amplicornis is a junior synonym (Trjapitzin 2002), per the identification labels of John S. Noyes ( BMNH) and personal communication of Robert L.Zuparko (California Academy of Sciences,San Francisco, California, USA). However, we are reluctant to describe it as a new taxon because taxonomy of this genus is very difficult; its Neotropical fauna in particular is poorly known, and there is no identification key available. Its female antenna certainly does not fit any of those New World species of Cheiloneurus illustrated in Trjapitzin & Zuparko (2005) and Trjapitzin & Triapitsyn (2008). Illustrated here, to facilitate recognition of this interesting undescribed species,are its female

( Figs.25 , 27–30 ) and male ( Figs.26 , 31–33 ).Body length of the dry-mount- ed females is 0.96 to 1.47 mm, and that of males is 0.83 to 0.96 mm.
