Ontogeny of the Tibial Spur in Megamelus Davisi (Homoptera: Delphacidae) and its Bearing on Delphacid Classification

  title={Ontogeny of the Tibial Spur in Megamelus Davisi (Homoptera: Delphacidae) and its Bearing on Delphacid Classification},
  author={S. Wilson and J. Mcpherson},
  journal={Great Lakes Entomologist},
The forms of the nymphal tibial spur in Megamelus davisi Van Duzee, and their relation to Muir's classification of delphacid subfamilies and tribes, are discussed. The evolutionary relationships among fulgoroid taxa, in our opinion, are not clearly understood. Although some attempts have been made to clarify these relationships on the basis of adult morphology (e.g., Muir 1930), the morphology of nymphs, including the ontogeny of anatomical features, has been virtually ignored. The delphacid… Expand
Life History of Megamelus scutellaris with Description of Immature Stages (Hemiptera: Delphacidae)
Abstract The five immature stages of Megamelus scutellaris Berg (Hemiptera: Delphacidae) are described and illustrated. The main characters that distinguish the various stages are body size, numberExpand
An Unusual Morphotype of Caenodelphax teapae (Fowler) (Hemiptera: Fulgoroidea: Delphacidae)
The unusual retention of juvenile features (i.e., paedomorphosis) in adult C. teapae is reported, which exhibits a predictable level of geographical variation in coloration and morphology. Expand
Megamelus bellicus (Hemiptera: Delphacidae): immature stages and biology
The main characters that distinguish the various stages are: body size, color, number of tarsomeres, espinulation of the metatibia and number of teeth on the spur; presence of sensoria on antennal pedicel. Expand
Species of Megamelus (Hemiptera: Delphacidae) Associated with Pontederiaceae in South America
This work is an update of knowledge on this genus, incorporating new specific diagnostic characters such as the length of ovipositor, shape and position of valvifer VIII, shapeand denticulation of the first and second valvulae, and coloration pattern. Expand
Preliminary evaluation of Megamelus scutellaris Berg (Hemiptera: Delphacidae), a candidate for biological control of waterhyacinth
Some feeding and development occurred on other species in the family Pontederiaceae which may have been laboratory artifacts, but which mandates a cautious, further evaluation of this planthopper prior to its use as a classical biological control agent. Expand
Redescription of Megamelus scutellaris Berg (Hemiptera: Delphacidae), a Candidate for Biological Control of Water Hyacinth
The macropterous and brachypterous male and the brachipterous female are described, and the holotype female is redescribed, and some biological aspects are recorded. Expand
The first representative of Progonocimicidae (Hemiptera: Coleorrhyncha) from mid-Cretaceous Burmese amber
Abstract Gakasha calcaridentata gen. et sp. nov. representing Progonocimicidae: Cicadocorinae (moss bugs) is described. It is the first record of Coleorrhyncha in mid-Cretaceous Burmese amber and theExpand
