According to Aburto-Oropeza and Balart (2001), H. chierchiae is a common species at Los Islotes, Gulf of California, with an occurrence frequency between 10-30%. In Cabo Pulmo, Mexico, this fish was considered scarce, with a relative abundance between 0.1-1%, and a relative frequency between 25-50% (Villarreal-Cavazos et al. 2000). In Bahía de Navidad, Jalisco, still in México, this fish was not captured within 12 (one each month) field trips throughout a year (Rojo-Vázquez et al. 2001). Surveys conducted at Gorgona Island coral reefs, Colombia (Zapata and Morales, 1997; Rubio, 1986), also could not find this species.
