Ametastegia armillata (Konow, 1905)

Emphytus armillatus Konow, 1905b: 163. Syntypes [assumed] ♀. Type locality: Algeria, Oran.

Protemphytus pallipes Spinola, 1808, var. nov. Benson in litt.: Rungs (1949), misidentification; recorded in Morocco, larva described, biology (host: cultivated Viola sp.).

Protemphytus afritus Zombori, 1979: 231-232. Holotype ♀. Type locality: Tunisia. Synonymy by Lacourt (1985).

Material examined.

Lectotype E. armillatus . 1♀ (DEI-GISHym4106), Oran. The only known existing former syntype. Oehlke and Wudowenz (1984) referred to this specimen as the “Holotypus”. In so doing, they fulfilled the requirements of Article 74.6 of the International Code of Zoological Nomenclature ( International Commission on Zoological Nomenclature 1999) and designated this specimen as lectotype. Badly damaged: remaining parts are the thorax, including right fore wing, bases of hind wings, most of fore and mid legs, coxae of hind legs, as well as abdominal tergum 1 and part of 2 (Fig. 8G, H ).

Notes.

The tegula (Fig. 8G ) and postspiracular sclerite (Fig. 8H ) are completely black. The mesoscutellum is rather densely punctate, but mostly with the interspaces unsculptured and shiny, except on a small matt postero-medial area where the punctures are nearly contiguous (Fig. 8F ).

Recorded only from North Africa (Algeria, Tunisia, Morocco). The male of A. armillata is unknown ( Lacourt 1985).
