Comments

In both mtg trees the monophyly of Carsidaridae and Pachypsylla is strongly or very strongly supported. Carsidaridae + Pachypsylla (Pachypsyllinae) and Homotomidae form a poorly supported sister group in the AN tree and both families are included in an unresolved basal assemblage in the CC tree. In the molecular analyses by Cho et al. (2019), Celtisaspis (Pachypsyllinae) is recovered as weakly supported sister-group of Homotomidae , rather than Carsidaridae , and the monophyly of Carsidaridae , Celtisaspis and Homotomidae is well supported. Hollis & Broomfield (1989) listed two putative morphological synapomorphies to link Carsidaridae and Homotomidae : 1) the presence of a pair of large tubercles on the metapostnotum, and 2) all three ventral sense organs of the metafemur in a basal position. These characters are present also in Pachypsyllinae , though the tubercles on the metapostnotum are relatively small in Celtisaspis . Cho et al. (2019) mention the bipartite male proctiger as a putative synapomorphy of Homotomidae + Pachypsyllinae . As in Aphalaridae , the three taxa discussed here form, depending on the type of analysis, an unresolved basal (paraphyletic) assemblage or a monophylum with contradicting relationships between the constituent groups. For reasons of consistency, we include the three groups in the single family Carsidaridae . The concept of Carsidaridae by Burckhardt & Ouvrard (2012) is broadened here to include also Homotomidae and Pachypsyllinae which is transferred from Aphalaridae .
