Amegilla (? Glossamegilla) tetrataeniata (Gribodo, 1894)

Anthophora tetrataeniata Gribodo, 1894 b: 275 , ♀ [Timor, MSNG]

Material examined.

West Timor / Timor-Leste • 1 ♀; Timor ; [likely 1892]; [likely W. Doherty leg.]; MSNG ( holotype) • 1 ♀; Timor [no further information]; M. A. Lieftinck det. 1966; RMNH .

Remarks.

This species is currently (to our knowledge) only known from two females which are the holotype ( MSNG) and one undated specimen ( RMNH). Amegilla tetrataeniata was placed into the subgenus Dizonamegilla by Brooks (1988), but this choice is confusing as the male is unknown and this subgenus is largely defined based on male characters. However, considering the biogeography of this species, the long tongue, the slightly swollen yellow-marked “ tubercles ” on the lower paraocular areas, as well as the presence of other Glossamegilla species in the region (the Lesser Sunda islands), a placement in the subgenus Glossamegilla seems more likely. Amegilla tetrataeniata is similar to A. anthracina but differs by the presence of white hairs on the gena, vertex, scutellum, and T 3-4. Without males and further data for this species, this placement is currently uncertain. It is included in the identification key for utility and to facilitate its further study.

Distribution.

Amegilla tetrataeniata is currently known only from the island of Timor ( Gribodo 1894 b; Brooks 1988).
