Diagnosis. Body length 595 μm (n=1). Funicle 5-segmented ( Fig. 145 View FIGURES 143–146 ); fore wing ( Fig. 146 View FIGURES 143–146 ) with venation extend- ing at least 0.66× wing length; marginal vein longer than submarginal vein and 2× as long as parastigma; postmarginal vein absent; 2 distal macrochaeta present. Male genitalia with two rod-like parameres.

Discussion. Only three specimens (CNC) of Arescon from America north of Mexico were seen. Arescon aspidioticola Ashmead (1879) , catalogue by Peck (1963: 51) and placed in Arescon , is probably correctly placed in Aphelinidae as discussed by Schauff (1984a: 39), so no named species are represented in the Nearctic. Incidentally, that species appears, incorrectly, under Mymaridae in the checklist of Chalcidoidea of Malta ( Askew & Mifsud 2016). Arescon has 5-segmented tarsi and represents an early lineage that appears to be most closely related to Kikiki Huber & Beardsley and Tinkerbella Huber & Noyes with 3- and 4-segmented tarsi, respectively; the latter two genera occur in the New World but have not yet been found in the Nearctic. Four other apparently related genera occur only in the Old World (Huber 2017).

Nearctic hosts. Unknown. An extralimital host is in Hemiptera : Cicadellidae ( Subba Rao 1966) .

Important references. Ogloblin (1957) treated the Neotropical species (as Xenomymar ), Triapitsyn & Berezovskiy (2003, 2004a) treated the Palaearctic species and Triapitsyn (2016) treated the Oriental species.

Arescon spp. The few specimens examined appear to represent two species. Distribution. USA: AL, FL.
