Material examined. Holotype: ♂, VIETNAM, Dong Nai Province: Cat Tien National Park , 25 km NW of Tan Phu (11º25'22.3"N, 107º25'42.5"E), 130 m, evergreen rainforest between HQ and Mr. Dong redwood tree, 26–29 August 2003, leg. P.J. Schwendinger ( MHNG, SV–03/14) GoogleMaps . Paratypes: 1♂, 1♀, same data as holotype GoogleMaps . 1♀, Lam Dong Province, road from Da Hoa (= Da Huoai) to Bao Loc , ca. 13 km southwest of Bao Loc (11º27'19.8"N, 107º43'03.8"E), 690 m, evergreen rainforest, 31 August 2003, leg.

Diagnosis. Males can be easily distinguished by the truncated tegular spine ( Fig. 415 View FIGURES 410–416. 410–416 ), the membranous posterior margin of the embolic base ( Fig. 413 View FIGURES 410–416. 410–416 ) and the pronounced RTA with apical modification ( Fig. 414 View FIGURES 410–416. 410–416 ). The female is recognized by the strongly elongated apical part of the spermathecae provided with 15 unequal coils.

Etymology. The specific epithet is derived from Latin (stem convolutes = past participle of convolvare = to roll up, to entwine).

Legs yellowish. Dorsum of opisthosoma dark brown, with reduced opisthosomal pattern. Dorsal scutum well-defined, longitudinal, occupying 1/3 of opisthosomal length.

Palp ( Figs 410–422 View FIGURES 410–416. 410–416 View FIGURES 417–423. 417–422 ). RTA represented by large prong, abruptly bending at half its length, apex with elevated lateral ridge. Cymbial fold broad, reaching apex. Tegular spine short and truncated. Conductor with distinctly pronounced triangular dorsal process. TA with triangular apico-prolateral fold; apico-prolateral process replaced by broad, sharply pointed, triangular flange directed posteriad; meso-prolateral ridge triangular. Embolic base subtriangular; membranous area well-developed, situated on lateral and posterior margin. Embolus filiform, elongated, originating at 90°.

Female (paratype). Total length 7.64; prosoma 3.82 long, 2.67 wide. Eye sizes and interdistances: AME 0.32, ALE 0.22, PME 0.24, PLE 0.24, AME–AME 0.12, AME–ALE 0.22, PME–PME 0.16, PME–PLE 0.42; MOQ: 0.72 long, 0.60 anterior width, 0.56 posterior width.
