Type series.
HT ♀, WA, Pilbara, 200 km E of Port Hedland, Yarrie Mining Area, Cundaline Ridge, 20°32'36"S, 120°09'35"E, 29 May 2009, Subterranean Ecology, bore-hole CU0046R, scraping, Western Australian Museum Entomology Reg. no. 72022 (WAM).
Differential diagnosis.
Small sized species (TL mm 1.43), easily distinguishable from B. currani by obtuse and not protruding basal angles of the pronotum.
Description of the HT ♀.
TL mm 1.43. Body elongated, depigmented, yellow-testaceous; integument shiny, with evident microsculpture, covered with short pubescence.
Head large, slightly narrower than the base of the pronotum. Labium without tooth. Antennae short, just exceeding the base of the pronotum when stretched backwards. Fronto-clypeal furrow slightly distinct; subrectilinear anterior margin of epistome.
Pronotum subrectangular (max. width / max. length ratio = 1.06) maximum width at the base of the anterior fourth, with basal border narrower than the anterior border, pronotum sides, anteriorly poorly arcuate, posteriorly subrectilinear and slightly sinuated, laterally completely smooth from anterior seta to basal angles, not emarginated before the base. Anterior angles rounded, slightly prominent; posterior angles obtuse, rounded, not protruding. Disc slightly convex, with very sparse and relatively short pubescence; median groove very shallow, slightly marked. Marginal groove relatively narrow and flat, not particularly enlarged near the base; anterior marginal setae inserted inside the marginal groove, approximately on the anterior fifth; basal setae inserted approximately on posterior angles.
Legs long and slender, with metatrochanters normal and metafemora unarmed.
Elytra subrectangular, very elongated (max. length/max. width ratio = 1.98), with parallel sides, slightly emarginated before apex. Disc convex; integument shiny, with evident microsculpture and very short, very dense and upright pubescence. Humeri very marked, squared; post-humeral margin denticulate, with distinct crenulations up to the discal pore; elytral apices separately rounded. Marginal groove narrow and evident up to the discal pore.
Chaetotaxy: scutellar pore large, foveate. Umbilicate series with 1st, 2nd,and 3rd pores of the humeral group almost equidistant; 4th pore clearly farther from the 3rd one and placed at the end of the basal third of the elytron; 5th pore placed well after the middle length of the elytron; 5th and 6th pores spaced out ca. 1/3 of the distance between 6th and 7th pores; 7th, 8th, and 9th pores not equidistant, 8th placed after the 9th one; 7th slightly displaced onto the disc. One single discal seta in the central area of the disc and placed at ca. 2/3 of the distance between the 6th and 7th pores.
Male. Unknown.
Etymology.
The name comes from the type locality: Cundaline Ridge.
Distribution.
Bylibaraphanus cundalinianus sp. nov. is known only from the type locality Cundaline Ridge, in the Yarrie Mining Area, 200 km E of Port Hedland, Pilbara, WA.
