Checklist of British and Irish Hymenoptera - Ichneumonidae Author Broad, Gavin R. text Biodiversity Data Journal 2016 4 9042 9042 http://dx.doi.org/10.3897/BDJ.4.e9042 journal article http://dx.doi.org/10.3897/BDJ.4.e9042 1314-2828-4-9042 Tryphon (Symboethus) duplicatus (Heinrich, 1953) Symboethus duplicatus Heinrich, 1953 discedens (Heinrich, 1953, Symboethus ) Distribution England, Scotland Notes H.K. Townes (pers. comm. to M.G. Fitton) regarded duplicatus as a junior synonym of exclamationis, the correct name for the species here called duplicatus being Tryphon hinzi (Heinrich, 1953). Townes also regarded 'duplicatus' (= hinzi sensu Townes) as comprising two species, one with red hind femora and one with black hind femora, also differing in characteristics of the egg. However, Shaw and Kasparyan (2005) regard a form of bidentatus with red hind femora as possibly being synonymous with hinzi . Further clarification is needed.
