Abstract:
Two new species of Trigonidiinae (Orthoptera: Grylloidea; Trigonidiidae), Trigonidium albarum sp. nov. and Svistella prominens sp. nov., were discovered in Sichuan Province, China. T. albarum sp. nov. has a similar coloration to Trigonidium rubrumoculum He & Ma, 2022 and can be distinguished by different ectoparamere; while S. prominens sp. nov. and Svistella anhuiensis He, Li & Liu, 2009 have similar morphological characteristics and are distributed in the same area, but the new species is characterized by a dark yellow body and a semicircular protrusion on the lateral lobe of epiphallus. This article presents descriptions and illustrations of the new species.

Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
