Pedicel greyish orange yellow; first flagellomere grey; arista with 3-4 dorsal and one ventral branches in addition to terminal fork. Face orange yellow. Gena orange yellow but dark brown on anteroventral margin. Clypeus orange brown. Palpus yellow. Cibarium: anterolateral projections longer than half width of anterior margin; medial sensilla 20-21; posterior sensilla approximately 20. Prementum ventrally slightly expanded, thicker in ventral than in dorsal portion from lateral view (Fig. 2B, C View Figure 2 ). Labellum with five pseudotracheae per side (Fig. 2B View Figure 2 ).
Thorax. Postpronotal lobe grey yellow, with two prominent setae: upper one 0.8 as long as lower one. Scutum and scutellum grey yellow but grey brown medially. Thoracic pleura grey yellow, with dark grey patches. Acrostichal setulae in six rows. Basal scutellar setae divergent; apicals cruciate.
Wing. C1 setae two, subequal in size. Halter opaque white.
Legs grey yellow; tarsomere Vs of all legs darker. Foreleg femur with 4-6 long setae in two rows on outer side. Fore- and mid-leg tarsomere Is longer than three succeeding tarsomeres together; hindleg one longer than rest together. Preapical, dorsal setae present on tibiae of all legs; apical setae on tibiae of fore- and mid-legs.
Abdomen. Tergites grey yellow, each posteriorly darker. Sternites yellow.
Terminalia (Fig. 2E-H View Figure 2 ). Epandrium with 11-14 setae on medial to dorsal portion and approximately four setae on ventral lobe (Fig. 2E View Figure 2 ). Surstylus with 6-7 apically pointed prensisetae arranged along caudobasal margin and 40-42 recurved setae on ventral portion of inner surface (Fig. 2E, F View Figure 2 ). Cercus nearly entirely pubescent except for lateral to ventral margin, with 21-24 setae (Fig. 2E, F View Figure 2 ). Hypandrium caudolaterally pubescent and fused to gonopod, with a pair of inward extended plates apically articulated to bases of parameres (Fig. 2G View Figure 2 ).

Etymology.
The specific name Lordiphosa curva = “curved” refers to the paramere basally curved ventrally.
Distribution.
India (Uttarakhand).
Remarks.
This species closely resembles L. neokurokawai in having only one ventral branch of arista, the long, apically pointed paramere curved ventrad medially and outward apically, and the epandrium and the surstylus nearly identical in morphology, but can be clearly distinguished from it by the diagnostic characters.
