The Neotropical genera of Paronellinae (Collembola, Entomobryoidea, Paronellidae) with description of two new species and redescription of Campylothorax mitrai

Abstract

Knowledge on Neotropical Paronellinae (Paronellidae) grew fast during the last years. Here we present an identification key and diagnoses to six valid genera, describe two new species: Salina zhanghi sp. nov. and Trogolaphysa ernesti sp. nov., redescribe Campylothorax mitrai Bellini & Meneses, and present notes on Brazilian fauna of Paronellinae. Salina zhanghi sp. nov. is very similar to Salina tristani Denis and S. hermana Mari Mutt in ventral head characters and mucro shape, but differs in dorsal chaetotaxy among other features. Trogolaphysa ernesti sp. nov. is similar to T. quisqueyana Soto-Adames, Jordana & Baquero in labial and dorsal chaetotaxy, empodial complex morphology and mucro shape, but it is different in color pattern, antennal morphology, and trochanteral and collophore chaetotaxy. After redescription C. mitrai most diagnostic features are the combination of dorsal head chaetotaxy and color pattern.
