Systematics and biology of the new genus Macrosaccus with descriptions of two new species (Lepidoptera, Gracillariidae).

Davis DR, De Prins J - Zookeys (2011)

Bottom Line: The new genus Macrosaccus Davis & De Prins is proposed for three species formerly assigned to the genus Phyllonorycter: Macrosaccus robiniella (Clemens), Macrosaccus morrisella (Fitch), and Macrosaccus uhlerella (Fitch); two new, closely related species: Macrosaccus neomexicanus Davis and Macrosaccus gliricidius Davis, are also proposed.Descriptions of the adults, pupae, larvae, life histories, and distributions are supplemented with photographs, line drawings, and scanning electron micrographs.The genus is endemic to the New World, with the invasive species Macrosaccus robiniella now widely established in Europe.

ABSTRACT
The new genus Macrosaccus Davis & De Prins is proposed for three species formerly assigned to the genus Phyllonorycter: Macrosaccus robiniella (Clemens), Macrosaccus morrisella (Fitch), and Macrosaccus uhlerella (Fitch); two new, closely related species: Macrosaccus neomexicanus Davis and Macrosaccus gliricidius Davis, are also proposed. Descriptions of the adults, pupae, larvae, life histories, and distributions are supplemented with photographs, line drawings, and scanning electron micrographs. Larvae of all species are serpentine/blotch leaf miners on various genera of the plant family Fabaceae. The genus is endemic to the New World, with the invasive species Macrosaccus robiniella now widely established in Europe.

Figure 18: Pupa of Macrosaccus robiniella. 83 Abdominal segments 7, 8, 9+10, ventral view (100 µm) 85 Detail of accessory cremaster, abdominal sternum 7 (100 µm) 86 Abdominal segments 8, 9+10, dorsal view (100 µm) 87 Abdominal segments 8, 9+10, ventral view (50 µm) 88 Caudal view of abdomen (100 µm) 89 Abdominal segments 8, 9+10, lateral view (100 µm). (Scale lengths in parentheses).

Mentions: The pupa of Macrosaccus is characterized by an accessory cremaster on abdominal sternum 7 that is unlike that of any other known gracillarid genus. This consists of a raised transverse ridge bearing ~ 18–21 mostly longitudinally oblique rows of short, blunt spines (Figs 84, 85). The accessory cremaster when present in Phyllonorycter differs greatly in consisting of a raised triangular area located midventrally on sternum 7 with 1–2 pairs of stout spines projecting laterally (Davis and Deschka 2001).
