Bibloplectus wingi Owens, new species

(Figs. 4a–4b)

Type Material. Holotype: (1 male) Shades State Park Montgomery Co., IN. 8.v.1961 // Berlese leaf litter W. Suter (FMNH) . Paratypes: (2 males, 3 females) same data as holotype. (FMNH) .

Etymology. This name is based on the same unpublished manuscript name provided by Orlando Park.

Diagnosis. The combination of the mesotibia with a small flange and the mesotibia not swollen near the midpoint is similar to characters of B. levis Owens and Carlton and B. silvestris Owens and Carlton, n. sp. The form of the aedeagus is unique among members of the genus (Fig. 4a–4b). Absence of distinguishing characters, external or internal, makes females of the genus almost impossible to differentiate.

Description. MALE holotype. Measurements: HL 0.06 mm, HW 0.15 mm; PL 0.13 mm, PW 0.20 mm; EL 0.25 mm, EW 0.31 mm; A1–6, respectively, 0.04, 0.08, 0.06, 0.07, 0.09, 0.03 mm; An1–11, respectively, 0.02, 0.02, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.02, 0.02, 0.06 mm; MP1–4, respectively, 0.01, 0.03, 0.01, 0.02 mm; GL 0.39 mm, GW 0.23 mm; ML 2.3 mm.

Integument: head, pronotum, elytra, and abdomen light brown, appendages yellow. Entire surface covered with sparse, semierect pubescence. Pubescence in gular area denser, slightly longer than on rest of body. Thorax: procoxae unmodified, protibiae unmodified, with setae denser towards apex. Mesocoxae contiguous, unmodified, mesotibiae with conspicuous small subapical spine, setae slightly denser towards apex. Metacoxae unmodified, conjunct, not fully separated by short intercoxal process of ventrite I, metatibiae with subapical spine on inner face, setae slightly denser towards apex. Abdomen: typical for genus. Genitalia: aedeagus asymmetrical. Median lobe barely extending beyond fimbriated margin of central sheath, distally expanded. Left and right lateral processes forming part of sheath extending down ¾ of aedeagal length. Ventral apparently absent.

Females. Integument, Head, Thorax, Abdomen: similar to male except eyes slightly smaller and legs unmodified.

Distribution. This species is only known from the type locality.
