Reshchikov, Alexey V., Soper, Anna & Van, Roy G., 2010, Review and key to Nearctic Lathrolestes Förster (Hymenoptera: Ichneumonidae), with special reference to species attacking leaf mining tenthredinid sawflies in Betula Linnaeus (Betulaceae), Zootaxa 2614, pp. 1-17 : 14

Lathrolestes scutellatus ( Ashmead, 1890) stat. rev.

Prionopoda scutellata Ashmead, 1890 , Holotype, female, USNM Homalomma eriocampoides Rohwer, 1915 , Holotype, female, USNM Homalomma caliroae Rohwer, 1915 , Holotype, female, USNM

This species was synonymized with Lathrolestes luteolator (Gravenhorst, 1829) by Barron (1994) i.q. Homalomma eriocampoides Rohwer, 1915 and H. caliroae Rohwer, 1915 .

The holotype specimens of these species are similar to that of European L. luteolator (Gravenhorst, 1829) but differ from the latter by the sculpture and punctation of the mesopleuron. Specimens of L. scutellatus ( Ashmead, 1890) from AEI and CNC show variation in sculpture and punctation of the mesopleuron and coloration but nevertheless individuals of L. scutellatus ( Ashmead, 1890) never have shiny smooth surface of mesopleuron and deep distinct punctures. L. scutellatus ( Ashmead, 1890) stat. nov. reestablished here as a valid species.
