Abstract: The family Chrysopetalidae has been poorly studied from the Pacific coast of Mexico compared to other families. Specifically from the southern Mexican Pacific, only two species of the family have been recorded in previous studies, Chrysopetalum occidentale and Paleanotus chrysolepis. In this study 311 specimens were revised, and nine species, belonging to six genera were found. Eight of these species are new records from the southern Mexican Pacific coast: Arichlidon watsonae n. sp., Bhawania cf. goodei, Chrysopetalum elegantoides, C. maculata, Hyalopale sp., Paleaequor psamathe, Paleanotus bellis and P. purpurea. A new species is also described, Arichlidon watsonae n. sp., which is characterized by the curved tips blades of the falcigers and their small and ovoid palps. Additionally, the genera Arichlidon and Hyalopale are recorded by first time from the Tropical Eastern Pacific.

Abstract: While most species of the Bellis genus are characterized by saponins in concentrations of ca. 4 % dry weight, Bellis annua only contains ca. 0.3% saponins. Hence positive-ion electrospray ionization mass spectrometry, including MS-MS analysis, has been used extensively for the rapid identification of the saponins of B. annua obtained after mild alkaline hydrolysis. The saponin composition is similar to that of other Bellis species and, in addition, glycosides of the rare bellisonic acid, which has recently been found in B. bernardii, have been identified.
