In the present paper, a new species of cynipid gall wasp, Liu & Pang, is described from several provinces in southern China. The new species is closely related to the recently redescribed (Kieffer, 1906). In addition to differences in adult and gall morphology, the new species is also readily separated by COI sequences, with a 6.2-8.9% genetic distance between populations of the new species and those of . A contrasting difference in sex ratios was also observed between the two species, with extremely female-biased (95.5-97.8% female) while male-biased to more balanced (5.4-43.5% female). PCR screening for infection further revealed contrasting infection rates between populations of and : the infection rate was 0% in and 100% in . Cytoplasmic incompatibility induced by is proposed as a potential mechanism of speciation of the sympatric and .

在本论文中，一种新的瘿蜂科瘿蜂——刘&庞氏瘿蜂，在中国南方的几个省份被描述。该新物种与最近重新描述的（基弗，1906年）密切相关。除了成虫和瘿形态的差异外，新物种还可以通过细胞色素氧化酶亚基I（COI）序列轻松区分，新物种群体与[另一物种名称缺失]群体之间的遗传距离为6.2 - 8.9%。在两个物种之间还观察到了性比的显著差异，[物种一名称缺失]极度偏向雌性（95.5 - 97.8%为雌性），而[物种二名称缺失]偏向雄性到较为平衡（5.4 - 43.5%为雌性）。对[某种感染相关名称缺失]感染的PCR筛选进一步揭示了[物种一名称缺失]和[物种二名称缺失]群体之间的感染率差异：[物种一名称缺失]的感染率为0%，而[物种二名称缺失]的感染率为100%。由[某种感染相关名称缺失]诱导的细胞质不亲和被认为是同域分布的[物种一名称缺失]和[物种二名称缺失]物种形成的潜在机制。
