Etymology. The species name is an abbreviation and derived from the Lao term "laai làak”, meaning “diverse”, referring to the diversity of the japonica-group in Southeast Asia; term in apposition.
Diagnosis. Small sized Clubioninae with a body length of 7.0 mm in females and strong opisthosomal and leg pattern (Figs 28-29), belonging to the japonica species-group. Females can be distinguished from those of C. campylacantha Dankittipakul, 2008, C. octoginta Dankittipakul, 2008, and C. suthepica Dankittipakul, 2008 by 1) having its epigynal atrium more rectangular (Fig. 22), 2) entire internal duct system being situated behind atrium (Fig. 23), 3) head of spermathecae of internal duct system laterad (Fig. 23).
Description. Female (holotype). PL 2.8, PW 1.9, AW 1.3, OL 4.2, OW 2.0. Eye diametres (Fig. 25): AME 0.14, ALE 0.16, PME 0.15, PLE 0.16.

Spermathecae compact, spermathecal bases short, not extending laterally beyond duct system (Figs 22-23).

Dorsal prosoma with marginal bands and marbled pattern in head region and on frontal chelicerae, the latter reddish brown. Sternum with margin darker. Legs with distinct dark patches.
