This species belongs to the C. concava species group and is most similar to C. engor Oláh & Johanson from Malaysia (Perak). It is distinguished from C. engor in having double warts at the ventroapical setose lobes, more ventrally located ventroapical setose lobes, and more-slender harpagones.
Male. Cephalic and thoracic scerites dark chestnut brown, legs paler brown. Maxillary palp formula: I-IV- III-II-V. Dorsum of head very dark chestnut, mostly denuded, warts discernible by bright white alveoli. Cephalic setal warts include: pair of large, ovoid, occipital compact setal warts; pair of lunular and posteradarching vertexal ocellar compact setal warts; pair of well-separated, obliquely elongated vertexal lateroantennal compact setal warts; single, rounded diamond-shaped vertexal medioantennal compact setal wart; pair of ventral, postgenal compact setal warts, attached to ocular grooves, very narrow warts with 4 strong setae; and single frontoclypeal large setal wart covering almost entire face below antennal sockets and above labrum, delineated laterally by frontogenal and clypeogenal grooves. Pair of small, brown, setal warts associated with cervical sclerite, apparently detached from slender, anterior cervical sclerite, located dorsally on whitish membranous neck. Swollen setal wart absent on proepisternum; few setae present on precoxale.
Spur formula 2,4,4; forelegs each with asymmetric tarsal claw, laterally flanked by setal bundle; posteroapical spur half as long and broad as anteroapical spur. Middle and hind leg claws asymmetric; anteroapical and anterosubapical spurs each smaller than respective posterior spurs.
Forewings 5.0 mm long; brown, with slightly darker veins; transparent hyaline line present on first half of stem of M1+2; Sc and R, and Cu2 and A1 separate to wing margin. Hind wings each with Sc and R meeting apically of crossvein r; crossvein r tangential with crossvein s; fork 1 absent.
Male genitalia. Segment IX annular; tergum short; sternum 2 times longer than tergum; anterolateral margins convex; dorsally and ventrally deeply concave; posterior margins each with bluntly triangular apical lobe, located immediately above articulation cavities of gonopods. Antecosta of segment IX broad, gradually narrowing ventrally and dorsally, antecostal suture visible; small acrotergite visible in lateral and dorsal view; spine row on posterolateral margins of segment IX each with subdorsal break. Apical lobes fused in dorsal view, bearing alveoli, serrated with minute, triangular, central projection. Area between segment IX and segment X forming gradual, almost invisible membranous slope. Segment X short; nearly quadrangular in lateral and dorsal views; basal part slightly sclerotized. Setaless mesocaudal lobe produced, with dark, marginal band, without dorsal intelobular gap. Dorsad-curving mesocaudal lobe quadrangular in lateral view. Ventroapical setose lobes small, located ventrolaterally, forming doublet visible in lateral and dorsal views. Sutures of segment X visible behind cerci. Cerci forming elevated warts, surrounded by less pigmented area. Coxopodites extending far beyond apex of segment X; straight, rod-like in lateral view; barely dilated at apex in ventral view. Harpagones slender, curving slightly mesad in ventral view. Phallotheca robust, basal section broad, obtusely bent; mid region slightly arched ventrally in lateral view; apex broadening into ventral bulge, curving dorsad at end. Endophallus long, broad, extending through and filling almost entire phallotheca, ending anteriorly in narrow, tube at gonopore. Chitinized endothecal process elongate, subquadrangular, strongly pigmented. Phallotremal sclerite long, vertical in lateral view.
Holotype male: INDONESIA (Sumatra): Bukit Barisan Selatan National Park, Barisan Mts., Way Pitias , 800 m, 17–19.vi.2008, light trap [J. Oláh, Jr.]— 1 male (OPC, in alcohol).
Distribution: Indonesia (Sumatra).
Etymology: Urhpirdana, „doublet” in Sanskrit, referring to the double warts of the ventroapical setose lobes.
