A new pachytroctid genus and species, Libanopachytrocta planaspinosa n. gen. n. sp., is systematically described and illustrated from an Early Cretaceous (Barremian) amber outcrop in the easternmost region of Lebanon. This new taxon displays two interesting morphological features, one in the forewings (forked anal vein), which has never been reported previously in the family, and another in the maxillary palpomeres (apical palpomere with sigmoidal outer margin and two flattened spines). The Pachytroctidae are the most species-diverse troctomorphan family represented in Lebanese amber. This new discovery showcases the first fossil record of the subfamily Pachytroctinae to date.
