Calapnita deelemanae Huber 2011: 59   , figs 72–73, 198–201 (♂♀).

Diagnosis. Males can be easily distinguished from C. subphyllicola   by bulbal appendix (pointed distally with small subdistal process, very similar to C. phasmoides   and C. anai   ; cf. Figs 101 View FIGURES 98 – 106 , 110 View FIGURES 107 – 111 ); from C. anai   and C. phasmoides   by 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.

New material examined. MALAYSIA-BORNEO: 2♂ 3♀, ZFMK (Ar 16001), Sabah, Mount Kinabalu , Poring Hot Springs , forest near beginning of Kipungit Trail (6.048°N, 116.706°E), 450 m a.s.l., on undersides of leaves, 7.viii.2014 (B.A. Huber, S.B. Huber) GoogleMaps   ; 1♂ 7♀ 2 juvs in absolute ethanol, ZFMK (Bor 207), same data GoogleMaps   . 1♂, RMNH ( ARA 17804 View Materials ), Poring , fruit plantation, canopy fogging, 23.i.2001 (collector not given)   . 1♀, RMNH ( ARA 17805 View Materials ), Poring Hot Springs (6.033°N, 116.833°E), canopy fogging Aglaia   sp., primary forest, 500–700 m a.s.l., 28.iii.1998 (A. Floren) GoogleMaps   . 1♂ 1♀ (2 vials), RMNH ( ARA 17806–07), 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) GoogleMaps   . 3♀ (2 vials), RMNH ( ARA 17808–09), Kinabalu National Park (coordinates on label probably wrong: 6.083°N, 116.65°E), 16/ 17.ix.2006 (A. Floren) GoogleMaps   . 5♂ 4♀ 2 juvs, ZFMK (Ar 16002), Sabah, Sepilok, Rainforest Discovery Centre, forest along Pitta Trail (5.875– 5.878°N, 117.937– 117.942°E), 30 m a.s.l., on undersides of leaves, 9.viii.2014 (B.A. Huber, S.B. Huber) GoogleMaps   ; 1♂ 1♀ 3 juvs in absolute ethanol, ZFMK (Bor 175), same data. GoogleMaps  

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 type locality (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 in new 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 eggs each, consistently lined up in a single row ( Fig. 9 View FIGURES 3 – 12 ).

Distribution. Widely distributed in Sabah, northeastern Borneo ( Fig. 281 View FIGURE 281 ).
