5. Embates duplicatus (Champion)

(Fig. 42, 244)

Ambates duplicatus Champion 1907: 165 . Holotype female, Mexico, labeled: “Type”, “ ♀ ”, “Cerro de Plumas/ Mexico / Hoege” (BMNH). Hustache 1938 (cat., Batames to subspecies); O’Brien

& Wibmer 1982 (cat.)

Batames duplicatus (Champion) . Casey 1922: 4

Embates [ duplicatus ]. Alonso­Zarazaga & Lyal 1999 (global combination of all species of Ambates Schönherr 1836 with Embates Chevrolat 1833 )

Diagnosis. Agrees with E. bisignatus in all details except: total length 6.1 mm; elytral macula of black scales narrower, only anterior portion extending to interstria 5; post­macular fascia of light yellow scales restricted to interstriae 2–3 (Fig. 42).

Plant association. Not known.

Material examined. MEXICO. Oaxaca: Cerro de Plumas ( BMNH); 30 km S Suchixtepec, 1300 m ( CMNC). Total 2 specimens .

Discussion. This taxon is known from two nearby locations in Oaxaca, Mexico (Fig. 244). It is not clear, whether or not E. duplicatus represents a species distinct from E. bisignatus . The latter species is smaller, while its vestiture appears variable enough to justify the inclusion of E. duplicatus . More material is needed to resolve this issue.
