D. curtus Portevin, 1903a: 162,

1921: 535 (as D. monilis, misidentification—see Note 1); Jeannel, 1936: 152 (assignment to group); Szymczakowski, 1961: 150; Salgado, 2002a: 255, 2007b: 143, 2008b: 221, 2010a: 294, 2014c: 124, 2016a: 63, 2018a: 65.

Syntypes (several specimens, [probably] in Grouvelle collection, in original description, with a male habitus illustrated) in MNHN [in Jeannel, 1936, males and females].

Type locality: Cochabamba [Department], Bolivia.

Distribution: Bolivia: Cochabamba Department; Ecuador: Cotopaxi, Pichincha, and Zamora-Chinchipe Provinces; Peru: Cuzco and Huánuco Departments; Venezuela: Distrito Capital.

Note 1: Considering the synonymic list in Jeannel, 1936: 152, it seems that this species was misidentified as D. monilis Murray [1856] in Portevin, 1921: 535 .

Note 2: Mexico (in caves): The records in Guerrero (in Szymczakowski, 1968: 18, as a doubtful record) and in Chiapas (in Peck, 1973b: 105, 1977: 186) are in error but the true identification of those specimens is not reported (SBP, personal data).
