 This new species resembles S. musagetes Malicky & Chantaramongkol from North Sumatra. However, the large paraproctal plates of the new species are rounded apically, not triangular, and have pronounced dorsoapical spine-shape processes. Also, the gonopods of the new species are composed of more slender and longer digitiform branches when viewed laterally.   
Male. Body pale, eyes black. Scapes shorter than head, without elongated setal tufts but with long setae present on mesal surfaces of scapes. Maxillary palp formula V-IV-(I,II,III). Anterior surface of head (or cephalic face) with narrow frontal area and enlarged genal areas; anterior tentorial pits demarcating frontal, genal, and clypeal cranial areas weakly developed. Wide frontogenal areas almost completely occupied by large frontogenal compact setose warts. Small, rounded, clypeogenal compact setose wart present on clypeogenal cranial area above articulation of each maxillary palp segment I. Labrum axially elongate, posterior part covered with diffuse setal wart. Haustellum narrow at base, broad at mid-length, with mesodistal hump; posterior half with parallel channels. Single, large subdiamond-shaped vertexal medioantennal compact setose wart dominating on head dorsum, between and behind scapes. Postgenal compact setose warts reduced in size and ventrally attached to ocular groove, forming narrow warts invisible in dorsal view. Coronal, lateral vertexal, occipital, and postoccipital grooves forming dark brown lines on head dorsum. Cranial areas and warts medium brown. Swollen proepisternal setal warts absent. Katepisternum of mesopleura acute anterodorsally.  
Spur formula 0,2,2, middle leg anteroapical spurs each 3 times longer than posteroapical spurs, hind leg anteroapical spurs each half as long as posteroapical spurs, middle leg apical spurs smaller than those on hind legs.  
Forewings 4.7 mm long; pale membrane with weak pattern due to presence of darker setae in groups.  
Male genitalia. Segment IX triangular in lateral view; narrowing gradually dorsally; lateroventrally setose; few setal alveoli on tergum and along border between segment IX and paraproctal plate. Segment X fused to tergum IX, shorter than paraproctal plates, sunken apically between paraproctal plates; nearly triangular in lateral view; slightly excised apicomesally in dorsal view; less sclerotized than paraproctal plates; covered with few minute setae. Paraproctal complex forming phallic guide; fused to tergum IX and venter of segment X, forming pair of broad plates. Paraproctal plates broader basally, extending ventrad as narrow bands down to gonopod articulations; protruding apicad dorsally; each with lateral apex rounded and with long, dark, dorsoapical spine. Cerci reduced to small setose surfaces near juncture of segments IX, segment X and paraproctal plates; almost invisible in lateral view. Gonopods each 5-branched; ventral and dorsal branches longest, digitiform; subdorsal branch broad; the other 2 branches short and very slender. Phallic apparatus with short, indistinct phallobase and membranous, amorphous endotheca, followed by single, slender, arciform paramere; reaching distal end of lateral flanges of phallicata. Phallicata arching, broad, with pair of dorsal flanges at mid-length, possibly housing phallotrema in trough between flanges and phallotremal sclerites. Apex of phallicata tapering in lateral view.  
 Holotype male: INDONESIA (Sumatra): Kerinci National Park, Tapan Road, 1000 m, 10.vii.2008, light trap [J. Oláh, Jr.]— 1 male (OPC, in alcohol).   
 Distribution: Indonesia (Sumatra).   
 Etymology: Pantangulil, from pantan, ”five,” and amgulil, “finger” in Sanskrit, referring to the gonopods each bearing 5 branches.
