Figure 2 from: Espinasa L, D. Bartolo N, E. Newkirk C (2014) DNA sequences of troglobitic nicoletiid insects support Sierra de El Abra and the Sierra de Guatemala as a single biogeographical area: Implications for Astyanax. Subterranean Biology 13: 35-44. https://doi.org/10.3897/subtbiol.13.7256

Figure 2 - Anelpistina quinterensis is one of the most troglomorphic described species of nicoletiids. This relatively large eyeless insect is albino and has extremely elongated appendages. Its habitat is restricted to very humid portions of the caves such as mud banks. It is doubtful that it can survive in an epigean environment. Its habitat probably reflects connectivity within a karstic area throughout geologic times and during the evolutionary history of the species.
