Macropygium subsulcatum (Amyot & Serville, 1843)  , REVISED STATUS

( Figs 6EView FIGURE 6; 11View FIGURE 11; 12View FIGURE 12; Table 1)

Oxyrhinus subsulcatus Amyot & Serville, 1843: 12  (removed from the synonymy with M. reticulare  ).

Macropygium subsulcatum: Dallas, 1851: 158  .

Lectotype female (here designated) ( Fig. 11View FIGURE 11): FRENCH GUYANE, Cayenne. Labels: Cayenne / Coll. Signoret. // subsulcat. / det. Signoret. ( NHM) 

Paralectotype female: FRENCH GUYANE, Cayenne. Labels: Cayenne / Coll. Signoret. // subsulcat. / det. Signoret. ( NHM) 

Distribution: French Guyane ( Fig. 12View FIGURE 12).

Diagnosis: Antennae five-segmented, first antennomere slightly longer than the second; sutural angles of valvifers VIII posteriorly projected; lateral angles of valvifers VIII roundly projected, covering the base of laterotergites IX.

Male. Unknown.

Female. Genitalia: valvifers VIII almost as long as wide; lateral angles of valvifers VIII rounded, slightly surpassing posteriorly an imaginary line connecting the spiracles of laterotergites VIII, and partially covering a third of the basal portion of laterotergites IX; sutural angles of valvifers VIII posteriorly projected; posterior margin of valvifers VIII concave near the sutural angles; laterotergites IX with mild lateral depression ( Figs 6EView FIGURE 6; 11DView FIGURE 11).

Comments. Macropygium subsulcatum  is currently known only from the two female types, collected in French Guyane ( Fig. 12View FIGURE 12). Macropygium subsulcatum  females are readily distinguished from other Macropygium  species by the relatively wide valvifers VIII and with broadly rounded apical angle ( Fig. 6EView FIGURE 6).
