Etymology.
The name is derived from Latin for third ( ‘tertius’) indicating that this is the third Langelurillus species described from India.
Diagnosis.
Males of L. tertius sp. nov. can be recognized by the small, thin slightly hook-shaped RTA; females by the simple, round copulatory openings; vertically oriented spermathecae, on which ducts have three loops (Fig. 3B-H View Figure 3 ).

Distribution.
Known only from the type locality (Maharashtra, India).
Natural history.
The new species was found inhabiting rocky patches in scrubland habitat. But they appear to be more common in forest patches than open scrubland. We often observed them perching on small rocks or dry leaf on the forest floor, where forest cover is up to 60-70%.
