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

Abstract

The last-instar larva and pupa of Prionispa champaka Maulik, 1919 are described and figured in detail. The chaetotaxy of the head, mouthparts, legs, and dorsal and ventral surfaces of the body are given. The larva of P. champaka mine in the leaves of Pollia japonica Thunb. (Commelinaceae) and pupate in the base of the mid-ribs. The adults were also observed feeding on the leaves of Pollia siamensis (Carib.) Faden ex D. Y. Hong. The prominent diagnostic characters of immature stages of other species of the three genera of Oncocephalini (Prionispa, Chaeridiona, and Oncocephala) are discussed.

Are dominant plant species more susceptible to leaf‐mining insects? A case study at Saihanwula Nature Reserve, China

“…Our 8 years of experience with leafminer collection in China, which began in 2007, has made us thoroughly familiar with most types of leaf mines, allowing us to easily identify plants with leaf mines and some leafminer groups (Bai, Xu, & Dai, 2015, 2016; Dai et al., 2013, 2014, 2018; Liao, Liu, Xu, Staines, & Dai, 2018; Liu et al., 2015; Xu, Dai, Liao, Diškus, & Stonis, 2018; Xu et al., 2017). According to our rearing records and leaf mine characteristics, leafminers in Saihanwula belong to four insect orders: Lepidoptera (moths), Diptera (flies), Coleoptera (beetles), and Hymenoptera (sawflies).…”

Mitochondrial genome of a leaf-mining beetle Prionispa champaka Maulik (Coleoptera: Chrysomelidae: Cassidinae)

“…P. champaka feeds on Pollia japonica Thunb. and P. siamensis (Craib) Faden ex Hong (Commelinaceae) and widely distributes in southern China (Chen et al 1986;Liao et al 2018). In this study, the complete mitochondrial genome of P. champaka was obtained and annotated for the first time.…”

“…It mainly occurs in the oriental tropics (Chen et al 1986;Staines 2015). The larvae of Prionispa are leaf-miners and generally form irregular blotch mines (Liao et al 2018). P. champaka feeds on Pollia japonica Thunb.…”

Descriptions of immature stages of Octodonta nipae (Maulik) (Coleoptera, Chrysomelidae, Cassidinae, Cryptonychini)

“…Many larvae and pupae in the subfamily Cassidinae have been described in detail (Maulik 1938, Gressitt 1960a, 1960b, Ford and Cavey 1985, Borowiec and Świętojańska 2003, Świętojańska et al 2005, 2006, 2013, 2015, Świętojańska and Borowiec 2007, Świętojańska and Kovac 2007, Świętojańska and Medeiros 2007, Świętojańska and Windsor 2008, Liao et al 2018), in the genus Octodonta , larvae of O. korthalsiae , O. subparallela , O. maffinensis were keyed and described by Gressitt (1960a); and preimaginal stages of O. depressa were described by Zaitsev (2006). As the only Octodonta species in China, the immature stage of O. nipae is still not described in detail, and we found O. nipae resembles another invasive species, Brontispa longissima (Gestro), especially in the immature stages.…”
