  • First evidence of Halyomorpha halys (Stål) (Hemiptera Heteroptera,
           Pentatomidae) feeding on rice (Oryza sativa L.)

    • Authors: D. Lupi, P. Dioli, L. Limonta
      Abstract: The brown marmorated stink bug, Halyomorpha halys (Stål) is a pest of numerous annual and perennial crops. Additional distribution records for H. halys are provided from northern Italy where rice is cultivated, and the presence of adults feeding on panicles gives the first evidence of an association between this pest and rice (Oryza sativa L.), a crop not previously recorded as a host plant.

  • The insect antenna: segmentation, patterning and positional homology

    • Authors: A. Minelli
      Abstract: The basic mechanism by which the antennal flagellum is subdivided into flagellomeres is probably the same in all insects, irrespective of whether the process occurs in the embryo, in the eye/antenna imaginal disc, or through a series of post-embryonic increments punctuated by moults. The ultimate origin of (all') flagellomeres is the first antennomere following the pedicel, from which split off in apical direction new primary flagellomeres, each of which is eventually the source of secondary flagellomeres, according to specific spatial and temporal patterns subject to heterochrony. Only a detailed knowledge of the underlying segmentation processes could provide the ultimate background for determining positional homology between flagellomeres of two antennae with different number of antennomeres. The antennae of the Heteroptera are likely re-segmented, as their second antennomere seems to include a flagellar component. The larval antennae of the holometabolans are temporal serial homologues of those of the adult, but their segmental composition is problematic. Significant progress will be done by understanding what differentiates antennomeres that divide, either embryonically or post-embryonically, from those that do not; and by discovering whether the spatial and temporal pattern of division along the flagellum depends on local cues, or on signals travelling along the whole proximo-distal axis of the appendage.

  • Agonum tulliae sp. n. from the Sila National Park (Calabria, southern
           Italy) (Coleoptera: Carabidae: Platynini)

    • Authors: A. Mazzei, P. Brandmayr
      Abstract: Agonum tulliae sp. n. is described from the Sila Massif upland in Calabria, Italy. This species is similar to Agonum (Olisares) sexpunctatum (Linné, 1758) as far as the external morphology is concerned, but it is easy to distinguish by the colour pattern, the shape of pronotum, and at best by the morphology of male genitalia. The study includes some remarks about the habitat and ecology of the new species. It lives only in the eastern part of the Sila massif and occupies the southernmost part of the distribution area of the Agonum sexpunctatum (Linné, 1758) complex in Italy.

  • Revision of the genus Chaetocladius Kieffer (Diptera, Chironomidae), 1st
           note: description of four new species from Italy

    • Authors: B. Rossaro, M. Montagna, G. Magoga
      Abstract: Four new species belonging to the genus Chaetocladius, known to occur in Italy, are here described as adult males: C. aedeagovirgatus sp. nov., C. subalpinus sp. nov., C. ticinoi sp. nov., and C. valdostanus sp. nov. C. aedeagolobatus is characterized by a robust aedeagal lobe, C. subalpinus and C. valdostanus by a characteristic inferior volsella, C. ticinoi by a tubercle on the basis of gonostylus. Geographical distribution of the other species known to occur in Italy is given. A key to adult males is presented.
