Following recent advances in the morphological interpretations of the tegmen basal cell margins in the Paraneoptera, a standardized and homology-driven groundplan terminology for tegmina types, structures and vein patterns in Hemiptera Fulgoromorpha, including fossils, is proposed. Each term is listed with a morphological definition, compared and linked to the main systems of planthopper forewing description that have been reviewed. The importance of a standardized and homology-driven terminology is stressed to enhance the quality of data in taxonomic descriptions and to strengthen phylogenetic morphological analysis results. When the interpretation of the origin of vein branches is render difficult, a three-step strategy for pattern recognition of the vein is proposed based on two principles: (1) vein forks are more informative than topology of the vein branches: a search for homologous areas, the nodal cells in particular, must first guide the recognition rather the number of branches of a vein, and (2) minimum of ad hoc evolutionary events should be invoked in the understanding of a modified vein pattern. Examples of some conflicting interpretations of venation patterns in planthoppers are discussed within different families for both extant and extinct taxa. For the first time, the concept of brachypterism is defined in a non-relative way independently from other structures, and the new one of hyperpterism is proposed; a reporting system is proposed for each of them.

The genus Poeciloterpa Stål endemic to the Philippines with 9 known species is reviewed. Four new species are described and illustrated: P. altissima Crispolon et Soulier-Perkins sp. nov., P. conica Crispolon et Soulier-Perkins sp. nov., P. gapudi Crispolon et Yap sp. nov. and P. mangkas Crispolon et Yap sp. nov. Illustrations and descriptions for the male genitalia are given for the first time for all the species except for P. nigrolimbata Stål known only by two female specimens. A key to species is provided. The type of habitats where the species are found is discussed and new host-plants listed.

The genus Lebinthus Stål, 1877 (Orthoptera: Gryllidae: Eneopterinae: Lebinthini) in the Philippines is studied. New locality records are provided for L. bitaeniatus Stål, L. sanchezi Bolívar, L. polillensis Baroga, Yap & Robillard, L. puyos Robillard, and L. luae Robillard & Tan. Six new species are described from Mt. Porras, Sibalom (L. dannybaletei sp. nov.), Mt. Balatukan, Misamis Oriental (L. parvus sp. nov.), Mt. Empagatao, Misamis Oriental (L. palaceus sp. nov.), Tarumpitao, Palawan (L. hamus sp. nov.), Mt. Malinao, Albay (L. magayon sp. nov.), and Boracay, Aklan (L. boracay sp. nov.). A distribution map, a taxonomic key, and an updated checklist of the genus in the Philippines are also provided.
