Calapnita bugis sp. nov. 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).

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).
