Pachybrachis sherriae Barney 2017
No full text51. Pachybrachis sherriae Barney, 2017 (Holotype in MCZ). Barney 2017a: fig. 8; map 2B. Remarks. Species treated in the revision of the luridus species-group (Barney 2017a) were inadvertently reported with the pronotal length (PL) and pronotal width (PW) reversed. The correct measurements for P. sherriae are PL = 0.63–0.75 mm and PW = 0.96–1.07 mm. Distribution. Recent collecting found a new state record for P. sherriae in Colorado and extended the range into the Sandhills region of western Nebraska.

Barney 2017 [printed, red paper].” Deposited in MCZ. The specimen is point-mounted with genitalia affixed to a second point. It is in excellent condition with all appendages intact. Paratypes. 4066 27♀♀. See Appendix 19. Description. Male. Yellow with rufous to fuscous punctures, standard maculae diffuse, often dark brown or fuscous; L = 1.90–2.20 mm (mean = 2.07 mm, n = 11); W = 0.98–1.17 mm (mean = 1.08 mm, n = 11); L/W = 1.84–2.00 (mean = 1.93, n = 11). Head: Slightly wider than thoracic apex, HW = 0.63-0.77 mm (mean = 0.70 mm, n = 11); eyes narrowly separated, IOD = 0.14–0.18 mm (mean = 0.16 mm, n = 11); IOD/HW = 0.20–0.24 (mean = 0.22, n = 11); face yellow with brown to black, W-shaped macula connecting the vertex and bases of antennae and up to base of upper lobe of eyes, punctation dense, antennae yellow-brown, not reaching elytral declivity. Pronotum: Yellow, M-shaped macula dark brown to black, broadly diffuse; incomplete punctation to lateral margins, PL = 0.56–0.71 mm (mean = 0.65 mm, n = 11); PW = 0.78–0.96 mm (mean = 0.88 mm, n = 11); PL/PW = 0.72–0.77 (mean = 0.74, n = 11). Elytra: Confused punctures in baso-sutural region, striae moderately impressed, irregular in middle, marginal interspace mostly impunctate. Pygidium: Dark brown to black with 2 oval, yellow maculae. Venter: Dark brown to black, upper sides of last ventrite yellow. Legs: Brown with standard yellow spots. Genitalia: Median lobe in en-face view wide, sides gently narrowing to ALM, then abruptly curved to extended terminus; pre- and post-orificial lengths negligible, OS large, with large, pigmented basal plates; median lobe in lateral view with inflated base, then narrowing at ALA, then inflated to ridgelike keel formed by 2 circular depressions as seen from sub-en-face view (Fig. 19G); DEO deflexed at near 60° angle, thereby creating a triangular, arrowhead-shaped area with a gently rounded terminus and 2 posteriorly projecting denticles. Arrowhead in dorsal view with a third, middle denticle that arises from distinct ridge formed along edge of inflated keel. Long setae present on rounded ALM and lateral edges of arrowheadshaped POL (Fig. 19). Twenty-five males from eight states were dissected. Female. As in male, except L = 2.17–2.38 mm (mean = 2.29 mm, n = 7); W = 1.18–1.33 mm (mean = 1.24 mm, n = 7); L/W = 1.74–1.92 (mean = 1.85, n = 7); HW = 0.75–0.83 mm (mean = 0.79 mm, n =7); IOD = 0.16–0.26 mm (mean = 0.22 mm, n = 7). Etymology. This species is named in recognition of Erin Smith Daugherty, Blacksburg, Virginia. Remarks. A large proportion of specimens (40%) of P. erinae were found from Québec, with a smattering from other states. Pachybrachis erinae superficially resembles P. relictus, but P. erinae is longer and narrower, with eyes closer together than P. relictus, thus providing a resemblance to Pachybrachis pectoralis (Melsheimer), but without the ocular lines and enlarged foreclaws. Distribution. This species is found from Québec and Michigan to Kentucky and South Carolina (Map 3B). Biological Notes. Label data reported collection on Quercus alba L., Quercus rubra L., and Quercus sp. in Québec, Canada. Specimens Examined.

FALL / COLLECTION [printed, white paper] // [circular blue disc signifying dissection by RJB] // HOLOTYPE / Pachybrachis / mcmeansi / R. J. Barney 2017 [printed, red paper].” Deposited in MCZ. The specimen is point-mounted with genitalia affixed to point. It is in excellent condition with all appendages intact. There are two paratypes (2♀♀) with identical collecting data. Paratypes. 5766 52♀♀. See Appendix 14. Description. Male. Yellow, with dark brown to black punctures, standard maculae diffuse, L = 2.08– 2.42 mm (mean = 2.32 mm, n = 10); W = 1.07–1.28 mm (mean = 1.22 mm, n = 10); L/W = 1.84–2.01 (mean = 1.91, n = 10). Head: Slightly wider than thoracic apex, HW = 0.71–0.86 mm (mean = 0.80 mm, n = 10); eyes widely separated, IOD = 0.20–0.28 mm (mean = 0.23 mm, n = 10); IOD/HW = 0.25–0.31 (mean = 0.29, n = 10); face yellow with large, dark brown to black, W-shaped macula connecting the vertex and bases of antennae and up to base of upper lobes of eyes, punctation dense in dark areas, antennae yellow-brown, not reaching elytral declivity. Pronotum: Yellow, with dark brown to black, M-shaped macula broadly diffuse, punctation dense in dark areas, more sparsely placed in pale areas, especially along lateral margins, PL = 0.64–0.77 mm (mean = 0.74 mm, n = 10); PW = 0.95–1.09 mm (mean = 1.04 mm, n = 10); PL/PW = 0.67–0.76 (mean = 0.71, n = 10). Elytra: Yellow with dark brown to black maculae in no particular pattern; punctation confused in baso-sutural region, striae incomplete basally, mostly regular laterally and apically. Pygidium: Finely punctate, weakly convex; dark brown to black, often with 2 small, oval, yellow maculae. Venter: Dark brown to black, yellow spot on last ventrite. Legs: Dark brown to black with yellow femoral and tibial spots. Genitalia: Median lobe in en-face view with large, oval OS within parallel-sided shaft, with reduced PRL. POL, best seen in the lateral view, slightly deflexed at ALM, thus creating a lateral ridge, and then further up towards apex it is deflexed at near 90° angle, thereby creating a triangular, arrowhead-shaped area with a gently rounded terminus and 2 posteriorly projecting, rounded denticles (Fig. 14). EFW = 0.29–0.39 mm (mean = 0.31 mm, n = 10); AAM = 0.15– 0.21 mm (mean = 0.18, n = 10); AAL = 0.16– 0.21 mm (mean = 0.19 mm, n = 10); AAW = 0.16–0.19 mm (mean = 0.18 mm, n = 10); AAL/ AAW = 0.92–1.14 (mean = 1.06, n = 10). Long setae present along edges of arrowhead down to initial deflexation. AAL/AAW ca. 1.0 indicates arrowhead essentially an equilateral triangle. Twenty-four males from 10 states were dissected. Female. As in male, except L = 2.30–2.63 mm (mean = 2.48 mm, n = 8); W = 1.19–1.36 mm (mean = 1.26 mm, n = 8); L/W = 1.85–2.21 (mean = 1.97, n = 8); HW = 0.81–0.92 mm (mean = 0.86 mm, n = 8); IOD = 0.18–0.34 mm (mean = 0.27 mm, n = 8); IOD/HW = 0.23–0.38 (mean = 0.31, n = 8). Etymology. This species is named in recognition of Orlando F. McMeans, PhD, Vice President for Research and Public Service; Dean and Director, Douglass Land-Grant Institute; Director, Agricultural and Environmental Research Station; Executive Director, WVSU Research and Development Corporation; West Virginia State University, Institute, West Virginia, for his unwavering support of this research. Remarks. Many of the specimens of this species were discovered in a unit tray in Fall’ s collection (MCZ-FALL) labeled as P. relictus. However, a dissection of Fall’ s P. relictus lectotype revealed a significantly different aedeagal median lobe. Pachybrachis mcmeansi has a very wide aedeagal median lobe with a distinctive, very large, arrowhead-shaped POL, as does P. walteri. However, P. mcmeansi has a secondary narrowing pre-arrowhead-shaped POL, and P. walteri, found only in Florida and Georgia, has a third, middle denticle. Distribution. This species is found in a scattered distribution from Maine to Arkansas (Map 2B). Biological Notes. A label cited a potential host plant as Amorpha fruticosa L. in Arkansas. Specimens Examined.
