Etymology. The specific epithet is taken from the Latin adjective longissimus , and means very long, referring to the slender embolus and copulatory ducts.

Diagnosis. This new species is similar to L. primus Tang & Li, 2009 , but can be distinguished by the much slender embolus, which has a ratio of 2.0 for the length of embolus/circumference (1.0 in L. primus ).

Description. Male (holotype measured): Total length 4.90. Prosoma 1.90 long, 1.70 wide; opisthosoma 3.10 long, 1.70 wide. Prosoma slightly convex, yellow, with sparse setae and small red spots. Tubercle of ALE and PLE grayish white, large and continuous. A white stripe connects with both of ALE. Eye measurements: AME 0.08; ALE 0.12; PME 0.06; PLE 0.11; AME–AME 0.14; AME–ALE 0.18; PME–PME 0.18; PME– PLE 0.42. MOA length 0.37 with front width 0.30 and back width 0.30.
