Family Macrothricidae Norman & Brady, 1867

43. Grimaldina brazzai Richard, 1892. Recorded by Álvarez (2010) and Fuentes-Reinés et al. (2012, fig 12). Pantropical taxon ( Smirnov 1992), probably it is represented by a series of taxa (H.J. Dumont, personal communication). In Colombia, it occurs in the Caribbean region.

44. Guernella raphaelis Richard, 1892. Recorded by Fuentes-Reinés & Elmoor-Loureiro (2011, figs 1-6) and Fuentes-Reinés et al. (2012, fig 8). Pantropical taxon ( Smirnov 1992) needs to be revised ( Frey 1988). In Colombia, it occurs in the Caribbean region.

45. Macrothix hirsuticornis N orman and Brady, 1867 s.lat. Recorded by Stingelin (1913). Only Palearctic populations could be regarded as M. hirsuticornis s.str. ( Smirnov 1992). Kotov (2007) concluded that all populations from southern South America belong to M. oviformis Ekman, 1900 . Nevertheless, in northern South America this species should be revised because its identity with M. oviformis is not obvious. In Colombia, it occurs in the Andean region.

46. Macrothrix paulensis (Sars, 1901). Recorded by Álvarez (2010). Neotropical species ( Kotov & Hollwedel 2004; Kotov et al. 2013 a). In Colombia, it occurs in the Caribbean region.

47. Macrothrix spinosa King, 1853. Recorded by Álvarez (2010); Fuentes-Reinés et al. (2012, fig 10) and Fuentes-Reinés (2014 a). Pantropical taxon ( Smirnov 1992). In Colombia, it occurs in the Caribbean region.

48. Macrothrix elegans Sars, 1901. Recorded by Álvarez (2010) and Fuentes-Reinés et al. (2012, fig 9). Neotropical species (Dumont et al. 2002; Kotov et al. 2004). In Colombia, it occurs in the Caribbean region.

Macrothrix laticornis (Jurine, 1820) . Recorded by Pearse (1916). Dubious records, the author most probably meant M. spinosa .

Macrothrix triserialis Brady, 1886 . Recorded by Stingelin (1913, figs 18-19) and Brehm (1956). M. triserialis is distributed in the Old World tropics and subtropics (Dumont et al. 2002; Kotov et al. 2004). Populations from South America belong to M. elegans , see above.

Macrothrix triserialis var. chevreuxi Richard in Stingelin (1913). The name is applied improperly: in reality M. chevreuxi is a name for African triserialis -like populations. Probaby, Stingelin (1913) dealt with M. elegans .

49. Onchobunops tuberculatus Fryer & Paggi, 1972. Recorded by Álvarez (2010) and Fuentes-Reinés et al. (2012, fig 11). Neotropical species ( Kotov et al. 2013 a). In Colombia, it occurs in the Caribbean region.

50. Streblocerus serricaudatus (Fischer, 1849). Recorded by Stingelin (1913). Holarctic species ( Smirnov 1992), nevertheless it has been reported from Australia and the Neotropics ( Paggi 1976; Smirnov & Timms 1983; Kotov et al. 2013 a). Populations from non-Eurasian localities should be revised. In Colombia, it occurs in the Andean region.
