Figs 180–187 “ Calapnita vermiformis ” (misidentification; only specimens from Sulawesi ): Deeleman-Reinhold 1986a : 45 ; 1986b: 212. Huber 2011 : 48 , figs 141, 147–152. Diagnosis . Distinguished from most species of vermiformis group (except C. dayak ) by wide obtuse tip of ventral flap of procursus ( Figs 180–181 ); from most (except C. saluang ) also by thin proximal part of bipartite cheliceral apophysis ( Fig. 184 ) and by strong and regular fringes at tip of embolus; from most (except C. bohol ) also by oval pore plates in transversal orientation ( Fig. 187 ); from several species also by narrow and distinct epigynal ‘knob’ ( Fig. 186 ). FIGURES 172–187 . Calapnita lawangan sp. nov. (172–179; RMNH, ARA 17815–16) and C. bugis sp. nov. (180–187; RMNH, ARA 17420). 172–173, 180–181 . Left procursi, prolateral and retrolateral views (arrow points at distinctive undulating ridge). 174, 182 . Left palpal trochanters, retrolateral views. 175, 183 . Left palpal femora, prolateral views. 176–177, 184–185 . Right male chelicerae, frontal and lateral views. 178, 186 . Epigyna, ventral views. 179, 187 . Cleared female genitalia, dorsal views. Scale lines: 0.3 mm. Etymology . Named for the Buginese people, an ethnic group in southwestern Sulawesi ; noun in apposition. Material examined. Holotype . INDONESIA-SULAWESI: ♂ , RMNH ( ARA 17817), South Sulawesi , 55 km from Udjung Pandang , 23 km from Camba [~ 5.05°S , 119.74°E ], under leaves in karst forest, 9 & 13–14.viii.1980 ( C.L. & P.R. Deeleman ). Other material . INDONESIA-SULAWESI: 3♂ 3♀ , RMNH ( ARA 17420), same data as holotype ; 1♂ 1♀ , RMNH ( ARA 17426), same data but only 9.viii.1980 . 2♂ 3♀ , RMNH ( ARA 17423), North Sulawesi , Dumoga , near Doloduo [~ 0.517°N , 123.917°E ], primary forest, from leaves, 27–30.viii.1982 (collector not given). Assigned tentatively . INDONESIA-SULAWESI: 2♂ 2♀ , RMNH ( ARA 17425), Central Sulawesi , Palu , Marena , Lore Lindu Reserve [~ 1.3°N , 120, 083°E], “dark little stream valley”, from leaves, 24.vii.1982 (collector not given). Description. Male ( holotype ) MEASUREMENTS. Total body length 5.2, carapace width 0.65. Leg 1 missing, tibia 2: 5.5, tibia 3: 3.4, tibia 4: 6.0. Distance PME-PME 200 µm, diameter PME 80 µm, distance PME-ALE ~30 µm; no trace of AME. COLOR. Entire animal very pale gray to whitish, legs with brown patellae and tibia-metatarsus joints. BODY. Habitus as in close relatives (cf. Figs 120, 122 ); ocular area barely elevated, each triad on very low hump; carapace without median furrow; clypeus unmodified; sternum barely wider than long (0.48/0.46), unmodified. CHELICERAE. As in Figs 184–185 , apophyses near lamellae clearly bipartite, proximal parts slender (similar to C. saluang ), with pair of barely visible lateral processes; without modified hairs; without stridulatory ridges. PALPS. In general similar to C. vermiformis (cf. figs 139 and 140 in Huber 2011 ); trochanter apophysis slender, as in Fig. 182 ; femur as in Fig. 183 , distal process at 44% of femur length; tibia length/diameter 0.51/0.25; procursus as in Figs 180–181 , with simple ventro-distal flat sclerite; bulb length 0.40; embolus length 0.60; embolus tip with strong and regular semi-transparent fringes. LEGS. Without spines and curved hairs; few vertical hairs. Male (variation). Tibia 1 in three other males: 7.7, 7.7, 7.8. The specimens from Lore Lindu Reserve are assigned tentatively because the tip of the procursus differs slightly (ventro-distal flat sclerite directed slightly more towards ventral). Female . In general similar to male; eye triads slightly closer together (distance PME-PME 180 µm). Tibia 1 in 3 females : 6.3, 6.5, 6.7. Epigynum as in Fig. 186 , weakly sclerotized triangular plate with small and slender anterior ‘knob’; internal genitalia as in Fig. 187 , much longer than wide, with small elongated pore plates in transversal orientation far from posterior margin. Distribution. Apparently widespread in Sulawesi ( Fig. 283 ).
