Pellorneum capistratum (Temm.) (Timaliidae)

Haemoproteus timalus Bennett, Bishop & Peirce, 1991 (Table 10)

Locality. – Malaysia: Sarawak; Indonesia: Java, Lingo lowland secondary forest , Java; Sep.2001 .

Type host. – Turdoides rubiginosus ( Kenya, East Africa). Additional hosts of Hae. timalus in SE Asia are Garrulax spp. and Heterophasia picadoides (Bennett et al., 1991) . Infection in Pel. capistratum from Sarawak consisted predominantly of macrogametocytes; the one microgametocyte traced was not measured.

Remarks. – The gametocytes adhere to the erythrocyte nucleus and either fill the entire space between the nucleus and erythrocyte wall or remain partly detached from the wall. Gametocytes from Pel. capistratum are more reminiscent of the type material than those from Garrulax spp. The seemingly fully-grown gametocytes never reach one or both extremities of the erythrocyte, in the type material this occur only in those not fully grown. Protrusions and spikes shown in the type description also occur in some presently reported macro- and microgametocytes. The macrogametocytes have blue-staining cytoplasm and sometimes disclose densely packed vacuoles. The pigment granules are often fewer than reported in the type material, mostly small and some accompanying a vacuole. Erythrocyte nuclear displacement is the same as in the type material. The growing young gametocytes become attached first to the erythrocyte nuclei.
