本文报道了鞘翅目(Coleoptera)叶甲科(Chrysomelidae)萤叶甲亚科(Galerucinae)柱萤叶甲属Gallerucida的三新种:基红柱萤叶甲G.basalis sp.nov.褐缘柱萤叶甲G.limbatella sp.nov.、小柱萤叶甲G.parva sp.nov.及一新纪录种:黑缘柱萤叶甲G.limbata(Baly,1878)。
The present paper deals with four species of the genus Gallerucido, three of them are new to science, one first recorded to China. All the species including in this paper are distinguished by Prof. Chen S. H. during his life time and described by Mr. Yang Xingke. The type specimens are preserved in the Insect Collections of the Institute of Zoology, Acadetnia Sinica.
1. Gallerucida basalis Chen, sp. nov. (fig. 1)
. Length. 11 mm. Head, prothorax. ventral surface of thorax and legs dark brown. Antennae and the middle portion of abdomen black. Sculcllum and the base of elytra reddish. Elytra yellow.
Antonnnae 1/2 as long as the elytra. Prothorax with a transversal groove, which discontinue at middle; disc with sparsely punctures and strongly in groove. Elytra with closely irregular punctures. Apex of abdomen with a pair of furcella.
Holotype , Longling County (24.5 N, 98.7 E), Yunnan Province, 1600 m, 20. V. 1955, by Wu rong et al.; paralype, 1, ditto. A distinct species, it can be distinguished by the abdominal furcella from the known species of the genus.
2. Gallerucida limbatella Chen, sp. nov. (fig. 3 ) Length. : 6.0 mm; : 6.5 mm.
: Head and antennae pitchy black; prothorax and scutellum reddish brown to dark; elytra orange or yellowish brown, suture, and basal lateral margins fo elytra blackish brown; external and inner margins of the epipleura, tibia and tarsi pitchy black.
Antennae 1/5 as long as the elytra. Prothorax with transversal subdepressed near the middle, deeper towards middle, surface closely covered with punctures stronger at sides. Scutellum trianglar and impunctures. Elytra with both large and small sized punctures, the large ones arranged in subregular rows between humeral angle and scutellum. The male gentalia is shown as in fig. 3.
Holotype , Huashan Mountain (31.5 N, 110.0 E), shaanxi Province 1670m, 27. V. 1963. by Mao Jinlong, allotype, Wuling Mountain (40.6 X, 117.4 E), Hebei Province, 1200-1800 m, 5. VII. 1963, by Jiang Shengqiao, paratypes 2, 2, Hebei, Nei Mongol Aut. Region, Shanxi Shaanxi Provinces, 1916-1931, by P. Licent.
This new species closely allied to Gallerucida limbata (Baly), but differs in the punctures of head and prothorax, the male genitalia is distinctly different.
3. Gallerucida parva Chen, sp. nov. (fig. 4) Length: 5.0mm; 6.0 mm.
Head, antennae, prothorax, scutellum, prosternitc and legs dark brown to pitchy black; one orange spot on the vertex; elytra and abdomen red; meso- and metasterniter reddish brown.
Antennae 1/2 as long as the elytra. Prothorax with sparsely and line punctures; disc without any concavity or depression. Elytra with disc raised, surface covered with strong and irregular punctures. The male genitalia is shown in fig. 4.
Holotypeo , Pr. Menghun (21.8 N, 100.3E), Xishuangbanna Dai Aut. Region, Yunnan Province, 1200-1400m, 28. X. 1958, by Wang Shuyong; allotype , ditto; paratypes 2, 1:1, the same as holotype, 1, Pr. Mengla (21.4 N, 101.5 E), Xishuangbannan Dai Aut. Region, 650 m, 10. VI. 1980, by Yu Han, 1, Pr. Menghai (21.9 N, 100.5 E), 1200-1600 m, 10. VII. 1957, by Zang Lingchao.
This new species very similar to G. reflecia Laboissiere, but, can be easily distinguished by the concavity and the punctures of the prothorax.
