Envenomation by the spotted harlequin snake, Homoroselaps lacteus (Linnaeus) 1754 (Serpentes: Atractaspidinae).

Two cases of envenomation from the small, semi-fossorial, front-fanged colubrid Homoroselaps lacteus are presented and the recent literature reviewed. In addition to local oedema and lymphadenopathy, the development of significant subcutaneous loco-regional bruising suggest that damage to capillary basement membrane and possibly other underlying anti-haemostatic effects may pertain to the clinical syndrome. Although local clinical effects may appear dramatic, due to the small volumes of venom that can be injected, it is considered that envenomation is unlikely to cause life-threatening effects.
