Holotype male in MNHN [in Peck & Cook, 2016 (aedeagus missing—Note: we recently learned that there are glass slides with male genitalia of the type specimens studied by R. Jeannel and kept separate at the MNHN collection (Michel Perreau, 2019, personal comm.; Jan Růžička, 2019, personal comm.—see Note under MNHN, in ‘Construction and Organization of the Catalog’), and this might be the case with this species), 2017; sex and number of specimens not given in original description, as in MNHN and BMNH, but a male was illustrated and may be interpreted as the holotype]. Type locality: México (inside of houses), [Ciudad de México State], Mexico.

Distribution: Guatemala: Alta Verapaz Department; Honduras: Francisco Morazán Department; Mexico: Chiapas, Ciudad de México, Guerrero, Hidalgo, Jalisco, Morelos, Oaxaca, Puebla, Querétaro, San Luis Potosí, Sinaloa, Tamaulipas, and Veracruz States; Nicaragua: Matagalpa Department.

Note: Not U.S.A.: The Texas record in Peck 1999c: 184 is a misidentification and a species record now described as D. texanus Peck & Cook, 2016: 96 which probably is also in adjacent Mexico and at least in the Sierra del Burro and Sierra del Carmen in Chihuahua and/or Coahuila.
