Based on this new material, the family is redefined. The phylogenetic relationships among the taxa of Lygistorrhinidae were studied by parsimony analysis using 43 morphological characters from the adults of 25 ingroup and one outgroup species. The cladistic analysis produced 14 most parsimonious cladograms. The solution obtained suggests unambiguously the following phylogeny: Palaeognoriste Meunier and "Lygistorrhina" asiatica Senior-White are successively sister groups of the rest of the Lygistorrhinidae; there is a clade Labellorrhina + ( Gracilorrhina + ( Blagorrhina + (( Seguyola Matile + ( Loyugesa Grimaldi & Blagoderov + Matileola Papp))))) with a monophyletic Lygistorrhina Skuse - Probolaeus Williston lineage as sister group. The phylogeny among the latter group remains largely unresolved.10aBlagorrhina brevicornis10aGracilorrhina gracilis10aLabellorrhina grimaldii ( Lygistorrhinidae- ) : Malaysia-10aLygistorrhinidae-: General-morphology10aMorphological-characters-analysis-and-significance-of-new-taxa; Blagorrhina blagoderovi10aNew-spe10aPhylogeny-1 aHippa, Heikki1 aMattsson, Ingegerd1 aVilkamaa, Pekka  uhttp://www.online-keys.net/sciaroidea/2000_/Hippa_et_al_2005_Lygistorrhinidae_phylogeny_gen_n.pdf
