Lordiphosa nigricolor species group: Baechli et al., 2004 : 264. Diagnosis. Acrostichal setulae in line with and anterior to dorsocentrals as long as others. Male foreleg tarsomeres without sex combs. Epandrium more or less projected or expanded on caudosubmedial margin near surstylus (Figs 3D , 4C, D , 6A, B , 7B ). Key to Indian species of the Lordiphosa nigricolor group
1 Epandrium with large flap covering surstylus on caudosubapical margin (Figs 4C, D , 6A, B ); oviscapt medially broad and humped in lateral view, distally narrowing and curved ventrad, with large, sclerotized perineal plate between them (Figs 4G, H , 6E, F ) 2
- Epandrium without large flap on caudosubapical margin (Figs 3D , 7B ); oviscapt neither medially humped in lateral view nor distally curved ventrad, without sclerotized perineal plate between them (Fig. 3G ) 3
2. Epandrial, caudosubapical flap serrate on dorsal margin (Fig. 4C, D ) Lordiphosa ayarpathaensis Kandpal & Singh, sp. n.
- Epandrial, caudosubapical flap not serrate on dorsal margin (Fig. 6A, B ) Lordiphosa makaibarensis Pradhan & Chatterjee, sp. n.
3 Paramere apically not hirsute, unevenly bifurcated (Fig. 3F ) Lordiphosa antillaria (Okada, 1984)
- Paramere apically hirsute (Fig. 7C, D ) 4
4 Hypandrium not shorter than twice of width (Fig. 7C ) 5
- Hypandrium shorter than twice of width 6
5 Ventral branches of parameres symmetric in length, apically truncated; arista with five dorsal and two ventral branches in addition to terminal fork Lordiphosa nigrovesca (Lin & Ting, 1971)
- Ventral branches of parameres asymmetric in length, apically pointed (Fig. 7C, D ); arista with 6-7 dorsal and 3-4 ventral branches (Fig. 7A ) Lordiphosa srinagarensis Sati & Fartyal, sp. n.
6 Epandrial, ventral lobe not extending beyond distal end of surstylus Lordiphosa coei (Okada, 1966)
- Epandrial, ventral lobe much elongated, extending beyond distal end of surstylus 7
7. Hypandrium triangular, anteriorly narrowing; dm-cu crossvein somewhat clouded Lordiphosa himalayana (Gupta & Gupta, 1991)
- Hypandrium quadrate; dm-cu crossvein clear Lordiphosa peniglobosa (Kumar & Gupta, 1990)
