Diagnosis.

The male of C. lala resembles those of C. grucollaris (Figs 40, 60A, 70A) in having a long, columnar conductor base and beak-shaped conductor apex but differs in the following: the embolar apex is coiled (Figs 42D, E, 60B) (vs. not coiled; Figs 40, 60A); the tegular apophysis is boomerang-shaped in ventral view (Figs 42D, 60B) (vs. petal-shaped; Figs 40B, D, E, 60A, 70A); the finger-like retrolateral tibial apophysis (Figs 42A, B, 70B) (vs. triangular; Figs 40A, B, 70A). The female of C. lala can be separated from that of C. grucollaris by the atrium anterior margin medially not concave (vs. medially concave) (cf. Fig. 87C and 87D), spermathecae tubular, consisting of base and head (vs. ascending spirally, consisting of base, stalk, and head) (cf. Fig. 95C and 95D). The female of C. lala also appears to be closely related to C. campylacantha (Dankittipakul and Singtripop 2008a: 38, figs 2-4, 13, 14, 38-40), C. octoginta (Dankittipakul and Singtripop 2008a: 39, figs 18-19, 45-47) and C. reichlini (Figs 37A-D, 79B, 87B) by the general shape of the atrium and vulva but can be easily distinguished from these species by the: (1) more rectangular atrium (Figs 43A, B, 87D) (vs. atrium more cambered); (2) spermathecae posterior to the atrium, well separated from atrium anterior margin (Figs 43C, D, 95D) (vs. spermathecae situated anteriorly, close to atrium anterior margin); (3) spermathecae separated by ca. one diameter (Figs 43C, D, 95D). (vs. spermathecae close together).

Description.

Male. (Fig. 43E, F): Total length 6.30; carapace 2.95 long, 1.96 wide; opisthosoma 3.53 long, 1.53 wide. Carapace brown, distinctly dark brown in ocular area, with a distinct pattern on pars cephalica consisting of a pair of dark, lateral bands and Ψ-shaped markings behind PER; ocular region distinctly narrowed, cervical groove and radial grooves indistinguishable; tegument smooth, clothed with short, dense setae. Eyes: AER slightly recurved, PER slightly procurved, the former wider than the latter. Eye sizes and interdistances: AME 0.11, ALE 0.15, PME 0.12, PLE 0.13, AME-AME 0.12, AME-ALE 0.10, PME-PME 0.27, PME-PLE 0.16, MOQL 0.36, MOQA 0.35, MOQP 0.52. Chelicerae robust and dark brown, dorsally with dark pattern. Cheliceral furrow with three anterior and two posterior teeth. Sternum yellowish white, 1.47 long, 0.96 wide. Labium and endites light orange. Legs brownish, all legs with conspicuous dark brown annuli on the distal parts of the femur, patella, tibia, metatarsus, and tarsus. Leg measurements: I 6.51 (1.78, 2.67, 1.32, 0.75), II 6.99 (1.90, 2.80, 1.44, 0.86), III 5.62 (1.72, 1.60, 1.74, 0.56), IV 8.29 (2.44, 2.93, 2.29, 0.60). Abdomen brown, with conspicuous anterior setal tufts; dorsum light yellow, antero-laterally with disconnected longitudinal bands, posteriorly with dark purple markings; venter with two indistinct purplish longitudinal markings.

Palp (Figs 42A-E, 60B, 70B). Tibia short, ca. 1/2 × cymbium length, with retrolateral apophysis; RTA digitiform, broad at base, apex truncated. Bulb more or less spherical, ca. twice longer than wide, oval; sperm duct sinuate, running an irregular course in the postero-retrolateral part of the tegulum. Embolus flagelliform; embolar base situated meso-prolaterally on the tegulum; embolar apex coiled, resting on an apical portion of the tegulum, covered by conductor in prolateral view. Conductor large, longer than 1/2 length of tegulum, with a heavily sclerotised and beak-shaped apex, base membranous, long, and columnar. Tegular apophysis heavily sclerotised, boomerang-shaped in ventral view.

Female. See Jäger and Dankittipakul (2010). Epigyne as in Figs 43A-D, 79D, 87D, 95D, habitus as in Fig. 43G-H.
