Chucallis Tao – Wikispecies link – Pensoft Profile
- Chucallis Tao, 1964[1]: 221. Type species: Myzocallis bambusicola Takahashi, 1921; by monotypy.
- Chucallis Tao: Tao 1990[2]: 139; Zhang 1999[3]: 227–228; Qiao et al. 2005[4]: 184.
Generic diagnosis
In alate viviparae, frontal tubercle not developed. Head without epicranial suture, clypeus without any processes. Antennae 6-segmented, processus terminalis slightly longer than base of the segment. Head and thorax without any dorsal processes. Abdominal tergites with dorsal spinal processes and developed marginal processes. Dorsal setae of body long and pointed, thick or fine. Rostrum short and stout. Wing veins without black borders. Fore coxae distinctly expanded, mid- and hind coxae normal. First tarsal chaetotaxy: 5, 5, 5. Siphunculi truncated, slightly longer than their basal diameters. Cauda knob-shaped. Anal plate bilobed. Gonapophyses fused.
In embryos, dorsal setae of body thick and long, pointed or stout. Dorsum of head with 2 pairs of anterior and 2 pairs of posterior setae. Thoracic tergites each with 1 pair of spinal and 1 pair of marginal setae, respectively. Abdominal tergites I–VII each with 1 pair of spinal and 1 pair of marginal setae, respectively, and spinal setae on tergites III, V and VII slightly displaced pleurally; tergite VIII with 2 dorsal setae. Siphunculi visible.
Distribution
Only found in China (Zhejiang, Fujian, Sichuan, Gansu, Taiwan and Hong Kong).
Host plants. Plants of Gramineae/Poaceae,feeding on bamboos,such as Bambusa stenostachya Hack., Dendrocalamus latiflorus Munro, Phyllostachys heteroclada Oliv., Thamnocalamus spathaceus (Franch.) Soderstr. and Indocalamus tessellatus.
Biology
The species colonize the undersides of the leaves of their host plants.
Comments
The genus is similar to Subtakecallis Raychaudhuri & Pal and Takecallis Matsumura (Quednau 2003[5]), but the alatae differ from those genera in having the clypeus without a nose-like processus (Subtakecallis and Takecallis: the clypeus with a nose-like processus), and some abdominal tergites with long, finger-like, seta-bearing spinal and marginal processes, the marginal ones on tergite IV being especially large (Subtakecallis and Takecallis: some abdominal tergites with small processes, not longer than their basal width).
