Bibloplectus ferroi Owens and Carlton , new species

( Figs. 5, 6, 7a–d )

Type Material. Holotype, male: USA: LA: St. Tammany Par. Abita Creek Preserve 30°31′25″N 89°58′07″W 11Aug 1999 FIT C3 C. Carlton, D. Prowell. ( FMNH).

Etymology. This species is named after Michael L. Ferro, LSAM alumnus, valued personal and professional associate of the authors, and current collections manager at Clemson University, South Carolina.

Diagnosis. The absence of an apical tubercle on the metatibia and the presence of a flange on the mesotibia ( Fig. 7c, d ) distinguish this species, externally, from all others in the genus. The form of the aedeagus is distinct ( Fig. 7a, b ), with a broad median lobe, the left and right lateral processes narrow and curved, and the ventral lobe about one-half the length of the aedeagus.

Description. Male. Measurements: HL = 0.14 mm, HW = 0.17 mm; PL = 0.17 mm, PW = 0.20 mm; EL = 0.30 mm, EW = 0.33 mm; A1–6, respectively, = 0.03, 0.07, 0.06, 0.06, 0.07, 0.02 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 = 0.41 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 elongate subapical tubercle. Metacoxae unmodified, conjunct, not fully separated by short intercoxal process of ventrite I, metatibiae unmodified apically, with series of spines. Genitalia: Median lobe broad. Left and right lateral processes elongate and narrowed distally, curving inwards, left dorsally directed and right ventrally directed apically. Ventral process about ½ length of aedeagus.

Female. Unknown.

Distribution. Louisiana: St. Tammany Parish.
