Redescription of immatures and bionomy of the Palaearctic species Dicladispa testacea (Linnaeus, 1767) (Coleoptera: Chrysomelidae: Cassidinae: Hispini), a leaf-mining hispine beetle

Abstract

Dicladispa testacea (Linnaeus, 1767) is a member of the tribe Hispini Gyllenhal, 1813 associated with plants of the family Cistaceae Juss. and is widely distributed in the Mediterranean Basin. Immature stages are described in detail, including line drawings, chaetotaxy, sculpture of integument, and SEM photos of morphological details. This is the first detailed description of immatures in the tribe Hispini, and this can be regarded as a model description for studies of other species in the tribe. Diagnostic characters for this species in comparison with other described larvae and pupae of the genus Dicladispa and the sympatric Hispa atra Linnaeus, 1767 are discussed. Some remarks on the biology of Dicladispa testacea, such as host plants, feeding patterns of adults, structure of larval and pupal mines, are also given.

Description of the last-instar larva and pupa of a leaf-mining hispine – Prionispa champaka Maulik, 1919 (Coleoptera, Chrysomelidae, Cassidinae, Oncocephalini)

“…It can be seen from above that the lateral scoli and abdominal apex of larva and pupa are the most important diagnostic characters between different species in these three genera as well as other Old World genera of leaf-mining hispines, such as Dactylispa Weise, 1897 (Chen et al 1986; Kimoto and Takizawa 1994; Lee and Cheng 2007, 2010; Zaitsev 2012; Dai et al 2012), Platypria Guérin-Méneville, 1840 (Kimoto and Takizawa 1994; Liao et al 2014), Dicladispa Gestro, 1897 (Chen et al 1986; Lee et al 2010; Świętojańska et al 2014). …”

The larval head structures of Podagricomela shirahatai (Chûjô) (Chrysomelidae, Galerucinae, Alticini) and morphological effects of leaf mining

“…The obviously plesiomorphic character states occur in larvae of Chrysomela : M. 9 is present, M. 18 has a tentorial origin, and M. 29 has only a single insertion, conditions which also occur in more generalized beetle larvae (e.g., Beutel ; Beutel and Molenda, ; Beutel and Friedrich, ). External apomorphic features shared by alticine larvae are the loss of stemmata, which are well developed in larvae of Chrysomela and other chrysomelid taxa (e.g., Cassidinae; Świętojańska et al, ), the loss of antennomere 3, and the presence of a well developed inner lobe of the mala (see Hua et al, for more potential apomorphies). An apomorphic feature found in alticine larvae and Chrysomela is the greatly reduced condition of the anterior tentorium.…”
