All theadults collected in STi: Melhus.T h i r d s t a g e. (Head and prothorax Plate I, 1)Length of head: 0.55-0.72 mm, width: 0.80-0.90 mm.Least pigmented parts of head and pronotum light yellow oryellowish white, meso- and metanotum and abdominal tergiteslight orange or yellowish brown.

Ocelli and ocellar areaabout as in B. argenteolum. Only four setae on frontal piece inarea where B. argenteolum has many. Nasale (Fig. 17a and b)totally different from that of B. argenteolum. Very narrow, butprojecting in the middle, front margin shorter than epicranialsuture: a:b = 0.13-0.19. Front margin usually well marked bya large tooth on each side. Two or three small teeth betweenthese. Antennae (Fig. 23) not as slender as in B. argenteolum,second joint: i = 1.7-2.1. First joint as long as or up to 1.2times longer than second joint. Third joint 1.2 to 1.5 timeslonger than second joint, and about twice as long as fourth,Retinaculum (Fig. 18a and b) in proportion to mandible largerthan in the previous species: r:ar = 0.2-0.3. Second joint ofmaxillary palpi: i = 1.2-1.4.Scutum of prothorax with 20-25 setae on each side of medianline. Mesonotum (Fig. 21) as long as or somewhat shorter thanscutum of prothorax: i = 0.50-0.53. 16-21 setae on each sideof median line.Legs (Fig. 19) about as in B. argenteolum. Claw, however, lessslender and its greatest length shorter relative to tarsus thanin B. argenteolunz. Abdominal tergites (Fig. 24) with about equalnumber of setae, from 9-12 on each side of median line. Ventralside of eighth segment (Fig. 22) has 36-50 setae.Micropores and sculpture about as in the previous species.
