Calapnita deelemanae Huber 2011: 59, figs 72–73, 198–201 (♂♀).
Diagnosis. Males can be easily distinguished from C. subphyllicolaby bulbal appendix (pointed distally with small subdistal process, very similar to C. phasmoidesand C. anai; cf. Figs 101, 110); from C. anaiand C. phasmoidesby distally strongly bent procursus (figs 198–199 in Huber 2011; very similar to C. subphyllicola). Females of these four species appear indistinguishable externally, but the round internal membranous ‘sac’ of C. deelemanae(fig. 201 in Huber 2011) might be distinctive.
Newmaterial examined. MALAYSIA-BORNEO: 2♂ 3♀, ZFMK( Ar16001), Sabah, Mount Kinabalu, Poring Hot Springs, forest near beginning of Kipungit Trail( 6.048°N, 116.706°E), 450 ma.s.l., on undersides of leaves, 7.viii.2014( B.A. Huber, S.B. Huber); 1♂ 7♀2 juvs in absolute ethanol, ZFMK( Bor207), same data. 1♂, RMNH( ARA17804), Poring, fruit plantation, canopy fogging, 23.i.2001(collector not given). 1♀, RMNH( ARA17805), Poring Hot Springs( 6.033°N, 116.833°E), canopy fogging Aglaiasp., primary forest, 500–700 ma.s.l., 28.iii.1998( A. Floren). 1♂ 1♀(2 vials), RMNH( ARA17806–07), Kinabalu National Park, Monggis( 6.220°N, 116.735°E; not as on labels: 6.083°N, 116.65°E), 23.ix.2006( A.

Floren). 5♂ 4♀2 juvs, ZFMK( Ar16002), Sabah, Sepilok, Rainforest Discovery Centre, forest along Pitta Trail(5.875– 5.878°N, 117.937– 117.942°E), 30 ma.s.l., on undersides of leaves, 9.viii.2014( B.A. Huber, S.B. Huber); 1♂ 1♀3 juvs in absolute ethanol, ZFMK( Bor175), same data. FIGURES 72–80. Calapnita semengohHuber, SEM micrographs (ZFMK, Ar 15999–16000). 72. Male chelicerae, oblique frontal view. 73. Male palpal tarsal organ. 74. Basis of left bulb, prolateral view (arrow points at membranous process; asterisk marks unidentified structure). 75. Detail of embolus, showing serrated edge. 76. Tips of procursus and embolus (arrow points at sperm duct opening). 77. Split hair on procursus. 78. Male ALS. 79. Female prosoma, frontal view. 80. Epigynum, ventral view. b, genital bulb; e, embolus; p, procursus. Scale lines: 10 µm (73, 75, 77, 78), 50 µm (74), 100 µm (72, 76, 79, 80). Notes. As mentioned in the original description, there is slight variation among males from different localities. This is confirmed by the new material: the appendix of males from Sepilok resembles that of males from the typelocality (Danum Valley), while males from Mount Kinabalu appear identical to the single male specimen previously known from this locality (i.e., with slightly longer subdistal side branch on appendix). Tibia 1 innew material: 6 males: 6.7–7.9 (mean 7.4); 11 females: 5.6–6.9 (mean 6.3).
Natural history. At Poring, most specimens were found on large leaves along the trail near the park entrance; the species seemed to be much less abundant in the forest. At Sepilok, specimens were found on leaves of various monocot and dicot plants. Egg-sacs contained 9– 12 eggseach, consistently lined up in a single row ( Fig. 9).
Distribution. Widely distributed in Sabah, northeastern Borneo ( Fig. 281).
