(61) Guernella raphaelis Richard, 1892

Indian records. Andaman & Nicobar Islands — Venkataraman (2000a); Bihar —Sharma B.K. & Sharma S. (2001); Manipur —Sharma B.K. & Sharma S. (2009a); Meghalaya —Sharma B.K. (2010); Tamil Nadu — Raghunathan & Suresh Kumar (2002, 2003); Rajasthan — Venkataraman (1990b); West Bengal — Venkataraman & Das (1993), Venkataraman et al. (2000); General record— Fernando & Kanduru (1984), Sharma B.K. & Michael (1987), Raghunathan & Suresh Kumar (2003).

Remarks. Valid species ( Smirnov 1976, 1992; Kotov & Ferrari 2010) described from Gabon ( Richard, 1892). Raghunathan & Suresh Kumar (2003) incorrectly listed “ raphalis ” as species epitheton.

Distribution. Circumtropical, but non-African populations need to be revised.

Gurneyella odiosa , see M. odiosa

Macrothrix capensis ( Sars, 1916)

Indian records. General record— Fernando & Kanduru (1984).

Remarks. For India it is a doubtful record. M. capensis was described as Echinisca from South Africa ( Sars 1916). Then similar populations were also found in Australia ( Smirnov & Timms 1983; Smirnov 1992). Smirnov (1976) regarded monodi as a subspecies of E. capensis . Perhaps this was a reason for the determination by Fernando & Kanduru (1984). Most probably they meant M. odiosa .

Macrothrix chevreuxi Guerne and Richard, 1892

Indian records. Assam — Biswas (1980); Rajasthan — Biswas (1971); General record— Raghunathan & Suresh Kumar (2003).

Remarks. It was described from Senegal and Gabon (Guene & Richard 1892). M. chevreuxi was found to be a junior synonym of M. triserialis (Michael & Sharma B.K. 1988; Smirnov 1992). Then Dumont et al. (2002) and Kotov et al. (2004) concluded that “ M. triserialis ” is a large group of cryptic species, but it seems that actual M. triserialis s.str. (described from Sri Lanka) is present in India. It is unknown what Biswas (1971) meant under this name, perhaps M. triserialis .

Macrothrix goeldi Richard, 1897

Indian records. Andhra Pradesh — Karuthapandi et al. (2012); Rajasthan — Nayar (1971); Tamil Nadu — Mohideen et al. (2008); Maharashtra — Pandit et al. (2007); West Bengal — Gurney (1907), Sharma B.K. (1978), Michael & Sharma B.K. (1988), Venkataraman & Das (1993), Sinha & Khan (2000), Khan (2003), Datta (2011); General record— Fernando & Kanduru (1984), Sharma B.K. & Michael (1987), Murugan et al. (1998); Raghunathan & Suresh Kumar (2003).

Remarks. It was described from Chile ( Richard 1897). Junior synonym of M. spinosa ( Dumont & Van de Velde 1977; Smirnov 1992; Kotov & Ferrari 2010).

Macrothrix groenlandica Lilljeborg, 1901

Indian records. Jammu & Kashmir— Brehm (1936); General record— Fernando & Kanduru (1984), Sharma B.K. & Michael (1987), Michael & Sharma B.K. (1988), Murugan et al. (1998), Raghunathan & Suresh Kumar (2003).

Remarks. It was described from Greenland, territory of Denmark ( Lilljeborg 1901). According to opinion of many recent investigators ( Hudec 1983; Margaritora & Usai 1983; Silva-Briano 1998; Kotov 2007, 2008), characters discriminating M. groenlandica from M. hirsuticornis fall within the variability of the latter. Therefore M. groenlandica is a junior synonym of M. hirsuticornis .
