( Fig. 8a–d )

Type Material. Holotype, male: USA, Illinois, Pope Co. 7 mi NNE Golconda at Grand Pierre Crk. 3 June 1986 UV light. E. A. Lisowski / LSAM0002152 . ( FMNH).

Etymology. This species is named after the first author’ s youngest brother who has provided many years of friendship and entertainment.

Diagnosis. This species is distinguished, externally, from all species in the genus except B. faulknerensis new species) and B. baylessae new species by the absence of a flange on the meta- tibia and the presence of a shortened flange and spine on the mesotibia ( Fig. 8c, d ). The form of the aedeagus is distinctive ( Fig. 8a, b ), with the median lobe straight, lateral processes elongate, and the ventral lobe strongly curved at its distal third and apically divided into two small, overlapping processes, the most dorsal process curved downwards over the more ventral one.

Description. Male. Measurements: HL = 0.16 mm, HW = 0.21 mm; PL = 0.17 mm, PW = 0.22 mm; EL = 0.34 mm, EW = 0.40 mm; A1–6, respectively, = 0.04, 0.06, 0.06, 0.06, 0.10, 0.02 mm; An1–11, respectively, = 0.05, 0.04, 0.02, 0.02, 0.02, 0.02, 0.02, 0.02, 0.02, 0.03, 0.09 mm; MP1–4, respectively, = 0.01, 0.03, 0.01, 0.02 mm; GL = 0.41 mm, GW = 0.25 mm; ML = 2.2 mm. Integument: Head, pronotum, elytra, and abdomen light brown, appendages light brown to yellow. Entire surface covered with semierect pubescence. Pubescence in gular area sparse, longer than on rest of body, a few capitate. Thorax: Procoxae unmodified, protibiae laterally with small subapical setae or small spines. Mesocoxae contiguous, unmodified, mesotibiae with a large subapical tubercle and associated spine. Metacoxae unmodified, conjunct, not fully separated by short intercoxal process of ventrite I, metatibiae unmodified apically. Genitalia: Ventral lobe elongate, strongly curved dorsally at distal 1/3 and apically divided into 2 small processes, the most dorsal process curved downwards over the more ventral one. Median lobe straight and slightly expanded distally. Lateral process to the left very elongate, composed of 2 processes that are closely associated.
