Etymology. The specific epithet, flabellatus (= fan-like), is the adjective of the Latin noun flabellum = fan.
Diagnosis. Males can be recognized by the TA provided with a sharply pointed basal tooth and a broad mesal ramus on the embolus ( Fig. 115 View FIGURES 114–121. 114 ). Females can be easily recognized by the laterally compressed, digitiform spermathecae (Fig. 1119).
Description. Male (holotype). Total length 6.82; prosoma 3.52 long, 2.70 wide. Eye sizes and interdistances: AME 0.32, ALE 0.22, PME 0.20, PLE 0.22, AME–AME 0.26, AME–ALE 0.60, PME–PME 0.20, PME–PLE 0.66; MOQ: 0.66 long, 0.70 anterior width, 0.60 posterior width. Leg measurements: I 13.14 (3.14, 4.12, 3.30, 2.56), II 10.90 (2.74, 3.42, 2.72, 1.98), III 10.96 (2.88, 3.30, 2.94, 1.82), IV 15.14 (3.66, 4.46, 4.72, 3.28).
Coloration (Fig. 1094). Carapace yellowish brown. Sternum yellowish. Chelicerae brown. Legs yellowish. Dorsum of opisthosoma pale brown; background mottled with numerous minute pale spots. Dorsal pattern: first pair represented by elongate-ovoid spots running longitudinally; second pair by round spots; third to fifth pairs by a series of chevrons.
Palp (Figs 1115–1118). Retrolateral margin of palpal tibia strongly pronounced, terminally rounded. RTA digitiform, bluntly pointed. Cymbial fold broad, situated basally, occupying less than half of cymbial length. TA elongated, apical ridge quadrangular, visible in prolateral view (Fig. 1118); apico-prolateral process bifid, provided with sharply pointed mesal branch and short lateral one; meso-retrolateral fold triangular, pointed mesad; baso-prolateral tooth sharply pointed. Tegular spine absent. Embolic base aligned in transverse direction, anterior margin straight, posterior margin medially excavated; membranous area triangular. Embolus relatively broad, bifurcated, branching subterminally, mesal ramus apically dilated, forming broad, semi-transparent flange, longer than curved lateral ramus.
Female (paratype). Total length 6.95; prosoma 3.60 long, 2.80 wide. Eye sizes and interdistances: AME 0.30, ALE 0.22, PME 0.22, PLE 0.22, AME–AME 0.28, AME–ALE 0.60, PME–PME 0.20, PME–PLE 0.68; MOQ: 0.66 long, 0.62 anterior width, 0.60 posterior width. Leg measurements: I 13.38 (3.20, 4.20, 3.36, 2.60), II 11.10 (2.80, 3.48, 2.78, 2.00), III 11.16 (2.92, 3.36, 3.00, 1.86), IV 15.42 (3.72, 4.54, 4.80, 3.32).
Coloration (Fig. 1095). As in males but pattern on dorsum of opisthosoma with first pair more elongated.
Genitalia (Figs 1110, 1119–1120). Epigynal plate elevated, represented by transverse, narrow band, with broad anterior median incision. Lateral borders more or less parallel. Spermathecae digitiform, curved backwards, apex blunt, lateral margins slightly excavated.
Natural history. Types of new species M. flabellata sp. nov. were collected from primary evergreen forest around 1,500–1,750 m asl.
Distribution. Known only from medium altitude belt (1,400 –1,800 m asl) of Mt. Kinabalu, northeastern Borneo.
