The white-backed planthopper (abbr. WBPH) (Sogatella furcifera (Horvath),
Homoptera: Delphacidae) is an important insect pest of rice in Taiwan occasionally.
Present study was conducted to investigate its population fluctuations, to determine
the factors affecting abundance, and to develop the models for forecasting its
population abundance based on the data collected from the monitored fields and traps
from 1982 to 2002 in Chiayi region. Accordin

No full textAhlbergia clarolinea Huang & Chen (Figs. 18–21, 63– 66, 71–72, 90–91, 104, 108) Ahlbergia clarolinea Huang & Chen, 2006: 317, figs. 4–6 for male and female genitalia, cpl. 12, figs. 1–3 for habitus. Material. CHINA: Yunnan province: 1 ♀ (CHH, holotype, dissected), Lijiang City, Yulongxueshan, 2800m, 29. IV. 2005, H. Huang leg..; 3 ♂♂, 1 ♀ (CHH, dissected), Lijiang, Yulongxueshan, 2600m, 26.IV. 2015, H. Huang leg.; 2 ♂♂ (CCAM, paratypes, dissected), Lijiang, Ludian, 2600–2900m, IV. 2006, A.-M. Chen leg.; 8 ♂♂, 4 ♀♀ (CHH; 2 ♂♂ & 2 ♀♀ dissected), Lijiang, Ludian, 2500–2800m, 13.V. 2014; 7 ♂♂, 4 ♀♀ (CHH; 2 ♂♂ & 2 ♀♀ dissected), Lijiang, Ludian, 2600–2700m, 28.IV. 2015 & 20.V. 2015, H. Huang & X.-D. Yang leg.; 1 ♂ (CZZH), Dali Bai Autonomous Region, Yunlong County, Tianchi, 20.V. 2014, Z.-H. Zheng leg.; 1 ♂, 1 ♀ (CHSJ), Kunming, IV. 2014, S.-J. Hu leg.. Sichuan province: 1 ♀ (CHH, dissected), Liangshan Yi Autonomous Region, Muli County, Liziping, 2700m, 5.V. 2014, X.-D. Yang leg.. Remarks. The female holotype was collected from Yulongxueshan whilst the male paratypes were collected from Ludian, thus the association of male and female requires a confirmation from more material. In a recent expedition made by the first author, specimens of both sexes were collected from both localities. An examination of male and female genitalia proved the original association of male and female to be correct. Distribution. Yunnan (Lijiang, Kunming, Yunlong), Sichuan (Muli).Published as part of Huang, Hao & Zhu, Jian-Qing, 2016, Ahlbergia maoweiweii sp. n. from Shaanxi, China with revisional notes on similar species (Lepidoptera: Lycaenidae), pp. 409-433 in Zootaxa 4114 (4) on page 431, DOI: 10.11646/zootaxa.4114.4.3, http://zenodo.org/record/27160
