Diagnosis. Resembling B. paradoxum, B. costatum, and B. lobatum sp. nov. in having males with the pre-anal appendages stout, apically rounded. The male differs from that of B. costatum in having each inferior appendage terminating in a small rounded area of short black setae, not an elongate brush. It is distinguished from B. costatum by having the lobes of the upper penis cover in ventral view acute apically, not flared distally as in B. costatum, and is distinguished from B. paradoxum by having the basal region of each inferior appendage subrectangular, not subquadrate, and from B. lobatum sp. nov. which has the mesal angle more strongly produced, rounded. Females resemble those of B. lobatum, having the apical lobes short, stout, and stepped (obliquely truncate).
Description. Mesothorax without mesoscutellar setate warts.
Male. Length of each forewing 6.8–7.5 mm (n = 4). Abdomen with small sharply pointed spur medially on sternite VII. Genitalia: Pre-anal appendages stout, rounded apically. Upper penis cover forming pair of elongate lobes of more or less uniform width for most of length, tapered slightly to apex. Inferior appendages each with coxopodite basally long, subrectangular to ovoid in ventral view, without any tufts of setae or mesal lobes, harpago slender at base, slightly dilated distally, with round pad of short, stout black setae apically.
Female. Length of each forewing 8.3–9.6 mm (n = 3). Terminalia: Apical lobes, slightly stepped toward rounded apices.
Distribution. Found from eastern New South Wales, from the Blue Mountains to the west of Sydney to south-eastern Queensland.
Etymology. Named after the Lorien Wildlife Refuge and Conservation Area near Lansdowne, New South Wales.
