Macropygium subsulcatum (Amyot & Serville, 1843), REVISED STATUS
(Figs 6E; 11; 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. 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. 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 6E; 11D).
Comments. Macropygium subsulcatum is currently known only from the two female types, collected in French Guyane (Fig. 12). Macropygium subsulcatum females are readily distinguished from other Macropygium species by the relatively wide valvifers VIII and with broadly rounded apical angle (Fig. 6E).
