Microspines in the pylorus of Pseudonannolene tricolor and Rhinocricus padbergi (Arthropoda, Diplopoda) Iheringia, Sér. Zool.
Miyoshi,Akio R.; Gabriel,Vagner A.; Fantazzini,Evandro R.; Fontanetti,Carmem S..
The aim of this paper is to report the morphology and distribution of microspines in diplopods pylorus, as these are important structures present along the alimentary tract of arthropods. The morphology of the internal surface of the pylorus of Pseudonannolene tricolor Brolemann, 1901 and Rhinocricus padbergi Verhoeff, 1938 was analyzed by SEM. Pseudonannolene tricolor presents two morphologically distinct pyloric regions: anterior and posterior. The first region is characterized by the presence of thin microspines that increase in number and size towards the posterior portion; the second region presents smaller and triangular-shaped microspines distributed throughout small plates. The pylorus of R. padbergi does not present differentiated regions; the...

Stridulatory file and calling song of two populations of the tropical bush cricket Eneoptera surinamensis (Orthoptera, Gryllidae, Eneopterinae) Iheringia, Sér. Zool.
Miyoshi,Akio R.; Zefa,Edison; Martins,Luciano de P.; Dias,Pedro G. B. S.; Drehmer,César J.; Dornelles,José E. F..
This study characterizes the calling song and ultramorphology of the stridulatory file of two geographically isolated populations of the tropical bush cricket Eneoptera surinamensis (De Geer, 1773) from city of Foz do Iguaçu, state of Paraná, and town of Rio Claro, state of São Paulo, Brazil, distant 1,000 Km from each other. The teeth are shell-shaped, the larger ones are distributed in the medium region of the file, decreasing gradually in size towards the edges. Specimens from Foz do Iguaçu have a file with 82 ± 9.8 teeth, length=1.89 mm ± 0.15 with 43.76 ± 5.94 teeth per mm (n=15). Specimens from Rio Claro present a file with 87 ± 9.81, length=1.96 ± 0.19 mm with 44.52 ± 4.61 teeth per mm (n=15). Statistical differences found between the two...
