Cephalia fenestrata Coquillett, 1900

Valid name. Myiomyrmica fenestrata ( Coquillett, 1900) (Ulidiidae) .

Cephalia fenestrata Coquillett, 1900: 24 (Kansas) .

Myiomyrmica fenestrata: Steyskal, 1961: 404 ; 1965: 646; Wallace, 2021: 9, 14, 69.

Material. Type. Holotype ♀: U.S.A.: “Onaga // Kansas ”, [Baker leg.], “ Cephalia // fenestrata // Coq.”,

“ Type // No. 4474 // U.S. N.M.” ( USNM), (examined) .

Remarks: Steyskal (1961) established a separate monotypic genus for this species in his key to the Nearctic genera of Platystomatidae and Otitidae , with a short diagnosis in a key couplet based on the frons being entirely shining and the wing narrow with a pale brownish disk and a whitish spot. Judging from Steyskal (1961: Fig. 5 ), it also differs by the male epandrium bearing trilobate surstyli lacking large prensisetae. It shares its long antenna, very wide, subtriangular palp, bulging upper part of the occiput and lack of proepisternal seta with Cephalia , Myrmecothea and Tritoxa , these synapomorphies apparently supporting monophyly of a lineage represented by these four genera.
