We describe a new species of the genus Liotyphlops from the Caribbean coast of Honduras in Nuclear Mesoamerica, a genus previously known only from Isthmian Mesoamerica and northern, central, and eastern South America. Our description is based on a single specimen found by chance. The new species differs from other congeners by unique combination of external morphological characteristics, specifically by the presence of three scales on the first vertical row of the dorsals, three supralabial scales, 425 dorsal scales, and dorsals in 22 series of uniformly pigmented scales across the body. The type locality represents the northernmost record for the genus and is located 920 km (airline) northwest of the previous record for Liotyphlops albirostris in Costa Rica. We developed an identification key for the genus and discussed natural history and biogeographical aspects of Liotyphlops, including the species described here.

The tick fauna of El Salvador is currently represented by 10 species of hard ticks (family Ixodidae) and 2 species of soft ticks (family Argasidae). This study aimed to report new and additional records of ticks and rickettsiae in El Salvador. During 2019-2021, a total of 216 specimens of ticks were collected from eight host species (domestic and wild animals) and in the environment among 15 geographic localities of El Salvador.

The gut microbiome plays an important role in insect evolution and ecology. Bacteria support the host's nutrition and defense and therefore play an important role in the fitness of the host. Halyomorpha halys is one of the most important invasive pest species in the world.
