The planthopper genusTrypetimorpha: systematics and phylogenetic relationships (Hemiptera: Fulgoromorpha: Tropiduchidae)

From micropterism to hyperpterism: recognition strategy and standardized homology-driven terminology of the forewing venation patterns in planthoppers (Hemiptera: Fulgoromorpha)

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.

Fine structure of sensory apparatus on the head of Cixiopsis punctatus

The external morphology of the heads of adult male and female Cixiopsis punctatus (Matsumura) (Hemiptera: Fulgoromorpha: Tropiduchidae) was studied using scanning electron microscopy. Eleven types of sensilla or sensory organs were identified: trichoid sensilla on the pedicel, scape, maxillae, and labium; campaniform sensilla on the antennal pedicel, antennal scape, maxillae, and labium; plate organs on the antennal pedicel; coeloconic sensilla in Bourgoin's organ and styloconic sensilla on the expanded flagellar base; Evans' organ and button-like sensilla on the maxillary plates; basiconic sensilla, peg sensilla, and coin-shaped sensilla on the labium. Styloconic sensilla on the expanded flagellar base and peg sensilla located between the dorsal sensory field and the opening of the maxillae and mandibles were first reported in Tropiduchidae. The external morphology, distribution, and abundance of sensilla located on antennae, maxillae, and labium in C. punctatus were illustrated.

A SEM study of antennal and maxillary sensilla in Zema gressitti Fennah (Hemiptera: Fulgoromorpha: Tropiduchidae)

The sensory organs on the antennae and maxillary plates of Zema gressitti Fennah (Hemiptera: Fulgoromorpha: Tropiduchidae) are studied using scanning electron microscopy. Four types of antennal sensilla are reported: trichoid sensilla on the antennal scape and antennal pedicel, plate organs on the antennal pedicel, campaniform sensilla on the antennal scape and antennal pedicel, and coeloconic sensilla in Bourgoin's organ on the antennal flagellum. Cuticular denticles and cuticular microtubercles are also present on the antennal pedicel. On the maxillary plates, three campaniform sensilla are discovered. Additionally, Evans' organs are described as placoid sensilla sunk into deep cuticular cavities on the maxillae below the antennae. The morphology of the sensory equipments in this species is provided for possible use in taxonomic and phylogenetic studies within the Tropiduchidae and Fulgoromorpha.

An annotated checklist of the planthoppers of Iran (Hemiptera, Auchenorrhyncha, Fulgoromorpha) with distribution data

A list of Hemiptera Fulgoromorpha (planthoppers) of Iran is provided, based primarily on literature records from 1902 to the present. In total 15 families and 235 species are recorded, with taxonomic details. Distribution data in Iran are given. Iranissus ephedrinus Dlabola, 1980 is transferred from Issidae to Nogodinidae. To resolve nomenclatural difficulty the following new combinations in Issidae are given: Iranodus dumetorus (Dlabola, 1981), Iranodus khatunus (Dlabola, 1981) and Iranodus repandus (Dlabola, 1981). Due to published generic synonomy the following are new combinations: Duilius seticulosus (Lethierry, 1874), Duilius tamaricis (Puton & Lethierry, 1887), Duilius tamaricicola (Dubovsky, 1966) and Duilius v-atrum (Dlabola, 1985).
