Halcyon semicaerulea hyacinthina Reichenow, 1900b: 249 .

Now: Halcyon leucocephala hyacinthina ( Reichenow, 1900b) . See Peters (1945: 198).

Syntype: ZMB 49.320 ( Fischer no. 6), skin, male, collected on “ Sansibar ”, 18.3.[18]77 .

Syntype (missing): Fischer no. 650, male, collected at Maurui, [17.01.1883].

Type locality: “ Sansibar ” [ Zanzibar, Tanzania] and “Usegua” [Useguha country, Tanga Region, Tanzania], from the original description.

Remarks: In the original description no type was chosen, nor were there measurements or inventory numbers for specimens, but localities “ Sansibar ” and “Usegua” were mentioned. Only one syntype from Zanzibar was found at the ZMB. Fischer however collected a male H. semicaerulea (no. 650) at Maurui on 17 Jan 1883 (Fischer 1884). Maurui is in the Lower Pangani River Valley at 5°07’S, 38°23’E in the area then known as Useguha or “Usegua”. The whereabouts of this syntype is unknown. There is no indication that this missing syntype was at the ZMB, so it is unclear whether Reichenow saw it or only cited it following Fischer (1884).
