Morphological and molecular data on the bat flies, Basilia silvae (Brèthes, 1913) and Trichobius parasiticus Gervais, 1844 parasitizing Chilean bats

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 3, Page 422-430, September 2025.
We determined morphological and molecularly two species of bat flies: T. parasiticus (Streblidae), and B. silvae (Nycteribiidae). We generated the first sequences for both species in the country for the cytochrome oxidase subunit I. We do recover monophyletic groups for both species, and we discussed the tree topology.

open access: yesAstronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT The close approach of comet C/2013 R1 (Lovejoy) allowed us to conduct an in‐depth study of the morphology of the inner coma. From the measurement of the dust emission structures expanding near the cometary nucleus in November–December 2013, we derived a slow rotation period of 47.8±1.2$$ 47.8\pm 1.2 $$ h.
