PSEUDOPOLYDESMUS PALUDICOLUS HOFFMAN, 1950 View in CoL
( FIGS 29–31 View Figure 29 View Figure 30 View Figure 31 )
Pseudopolydesmus paludicolus Hoffman, 1950: 222 View in CoL , fig. 4, ♂ HT (USNM, vidi, gonopods missing). – Chamberlin & Hoffman, 1958: 70. – Hoffman, 1999: 445.
Pseudopolydesmus paludicola [sic] – [ Withrow, 1988: 111, figs 95, 99, 103, 126, map 9, table 11.]
Diagnosis
Size: Small, with male body length measured at 11 and 13 mm (N = 2; Withrow, 1988: 111). Comparable in size to Ps. minor and Ps. caddo . Clearly smaller than all other congeneric species. May be mistaken, e.g. for the similarly sized Po. inconstans , because, unlike in most Pseudopolydesmus , the collum is narrower than the mandibles and tergal setae are clearly visible under the dissecting microscope.
Paranota and tergal sculpture ( Fig. 29 View Figure 29 ): Corners of paranota forming a longitudinally oblong rectangle. Leading and distal margins moderately curved. Denticles strongly distinct with unusually long, easily visible setae, but ALC indistinct. Trailing margin concave, strongly curved. Anterior blister row thicker than median blister row along its entire breadth, and MB row thicker than PB row. Individual MBs subequal in area, as are individual PBs. Central paranotal blisters occupying two-thirds of paranotal breadth. Lateral blisters aligned with longitudinal axis. Tergal and paranotal blisters also with unusually long, easily visible setae.
Gonopod ( Figs 30 View Figure 30 , 31 View Figure 31 ): Gonocoxa ventral lobe with two gonocoxal plates stacked dorsoventrally ( Fig. 31 View Figure 31 ). Telopodite roughly boomerang-shaped, abruptly kinked distal from pulvillus, curving terminally. Pulvillus very small (comparable in size to process m1), pointed, slightly closer to base of acropodite than terminus. Processes e1, e3 and m4 absent. Process e2 projecting laterally ( Fig. 30C View Figure 30 ); e4 unusually large, spike-shaped. Process m1 unusually large, subtriangular, medial of pulvillus; m2 and m3 medium-sized, connected by a shared lamina ( Figs 30–31 View Figure 30 View Figure 31 ); m2 offset laterad from m3 ( Fig. 30C View Figure 30 ).
Type notes
(♂ HT, USNM, vidi): From Sand Bridge , City of Virginia Beach, Princess Anne Co., VA, USA, collected 8 May 1949 by L. M. Carter, H. I. Kleinpeter and R. L. Hoffman . ♂ HT intact with gonopods removed (gonopods non vidi).
Distribution
Coastal plain of southeastern Virginia south to South Carolina.
