Abstract
Summary: Inbarian. gen. is proposed based on type species Geoica swirskii Remaudière & Inbar, 2004, resulting in a new combination, Inbaria swirskii (Remaudière & Inbar, 2004) n. comb. Inbaria easily differs from all Pistacia gall-producing aphids of the tribe Fordini by the size of the primary and secondary rhinaria in fall migrants. Inbarian. gen. is differentiated morphologically from the similar genera Geoica Hart, 1894 and Slavum Mordvilko, 1927. Genetically (COI), the two genera Geoica and Inbaria show a large divergence of more than 9% of the sequence. Notes on some morphological characters in apterous fundatrigeniae and descriptions of the embryo of the apterous exule, within alate viviparous females of I. swirskii, are provided.

Funding Information:National Notifiable Disease Report System of Chinese Disease Prevention and Control Information System and Liwan District Center for Disease Control and Prevention of Guangzhou. Frequency analysis (proportions), histograms, and percentage stacked area plots were used to describe the epidemiological characteristics of the outbreaks. The incubation period and time-varying reproduction numbers (Rt) estimations were used for the further analysis. Results By June 18, 2021, a total of 127 COVID-19 cases caused by Delta variant was reported in Liwan district. The youngest case was aged 2 years and the oldest was aged 85 years. There were 18.9% (24/127) aged <18 years, 43.3% (55/127) aged 18-59 years, and 37.8% (48/127) aged ≥60 years, the male to female ratio of the cases was 1∶1.35 (54∶73). The cases were mainly retired people (32.3%, 41/ 127), the jobless or unemployed (18.1%, 23/127), and students (16.5%, 21/127). The infections mainly occurred in Baihedong (70.1%, 89/127) and Zhongnan street (23.6%, 30/127) communities in the southern area of Liwan district. The median incubation period of the Delta variant infection was 6 days (range: 1-15 days). The clinical classification were mainly common type (64.6%, 82/ 127). The basic reproduction number (R0) was 5.1, Rt which once increased to 7.3. The transmissions mainly occurred in confined spaces, such as home (26.8%), restaurant (29.1%), neighborhood (3.9%), and market (3.1%), the household clustering was predominant. Close contacts tracing (66.1%) and community screening (33.1%) were the main ways to find the infections. Conclusion The COVID-19 outbreak caused by Delta variant in Liwan district of Guangzhou was highly contagious, with the obvious characteristics of household clustering and high proportions of cases in adults aged 18-59 years and elderly people aged ≥60 years. 【Key words】 COVID-19; SARS-CoV-2; B.1.617.2(Delta) variant; Epidemiological characteristic Fund programs: National Natural Science Foundation of China (81773543, 81973150); Guangdong Basic and Applied Basic Research Foundation (2021A1515011591, 2020A1515110230); Natural Science Foundation of Guangdong Province (2021A1515011765)
