Gen.n. Ind206: Eberle et al. 2018 (molecular data); Huber et al. 2018: fig. 7.

Type material. INDONESIA: ♂ holotype, ZFMK ( Ar 20648), Halmahera, degraded forest along river near Sofifi (0.715°N, 127.586°E), 130–180 m a.s.l., 11.xi.2009 (S. Sutono), originally in pure ethanol, later transferred to 80% ethanolGoogleMaps  .

Other material examined. None

Etymology. The species name is derived from the type locality; noun in apposition.

Diagnosis. Morphologically, the genus/species differs from most other known Pholcidae  by shape of abdomen in dorsal view ( Fig. 264View FIGURES 264–271; wide and obtuse posteriorly, similar only in Kairona  gen. n. and in some species of Metagonia Simon, 1893  ). Male pedipalp similar to some species of Belisana Thorell, 1898  (e.g., B. fiji Huber, 2005  , figs 626–627 in Huber 2005a), but with distinctive retrolateral process on procursus ( Fig. 273View FIGURES 272–274). Live specimens are apparently unique among Pholcidae  by their pale orange ocular area ( Fig. 264View FIGURES 264–271).

Description. Male (holotype). MEASUREMENTS. Total length 1.35, carapace width 0.50. Distance PME-PME 130 µm; diameter PME 60 µm; distance PME-ALE 10 µm; AME absent. Leg 1: 9.5 (2.4 + 0.2 + 2.4 + 3.6 + 0.9), tibia 2: 1.4, tibia 3: 0.8, tibia 4: 1.5; tibia 1 L/d: 48.

COLOR (in ethanol). Prosoma and legs pale whitish except for orange band between eye triads. Abdomen pale ochre-yellow with some indistinct darker marks dorsally.

BODY. Habitus as in Fig. 264View FIGURES 264–271. Ocular area not elevated. Thoracic furrow absent. Clypeus unmodified. Sternum wider than long (0.28/0.24), unmodified. Abdomen distinctively angular in dorsal view.

CHELICERAE. As in Fig. 274View FIGURES 272–274, with pair of simple pointed apophyses distally and pair of transparent processes proximally.

PALPS. As in Figs 272–273View FIGURES 272–274; coxa unmodified, trochanter with ventral apophysis, femur moderately widened, larger than tibia; procursus slender, with distinctive retrolateral process and sclerotized and membranous distal elements; bulb with cylindrical embolus, without further process.

LEGS. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 3.5%; tibia 1 without prolateral trichobothrium; tarsus 1 pseudosegments not seen.

Female. Unknown

Distribution. Known from type locality only ( Fig. 349View FIGURE 349).

Natural history. The male was collected from the underside of a green leaf in a degraded forest ( Fig. 341View FIGURES 336–341).
