Myiophanes zebrina and M. incompta will run to M. greeni (couplet 2) in the identification key presented by WYGODZINSKY (1966: 271). The changes to the key provided below will allow recognition of the species. 2. Anterior lobe of pronotum white, a central oblique spot on each side fuscous; abdomen white, with five broad, transverse, fuscous annulations 2a - Colour different 3 2a. Fore lobe of pronotum 0.9 times length of hind lobe. Sri Lanka Myiophanes greeni DISTANT, 1903 Fore lobe of pronotum 1.05-1.5 times length of hind lobe 2b 2b. Pronotum more elongate, about 2.45 times longer than its greatest width, extremely narrow at the level of transverse constriction between the fore and hind lobes (fore lobe more than 6 times longer than width across constriction); fore lobe about 1.5 times longer than hind lobe. India Myiophanes zebrina sp. n. Pronotum less elongate, about 2.3 times longer than its greatest width, rather stout at the level of transverse constriction between the fore and hind lobes (fore lobe about 4 times longer than width across constriction); fore lobe about 1.05 times longer than hind lobe. Pakistan Myiophanes incompta sp. n. Remarks - Myiophanes zebrina sp. n. and M. incompta sp. n. are closely related to but undoubtedly differ from M. greeni. Most of the morphological characters and the colouration of the two new species are very similar; however, the apparent differences between the shape of the pronotum, sharply distinguish the two species. As each species is known only from a single specimen, of different sex, there is a slight possibility that they represent the male and female of the same species. However, because no similar sexual dimorphism is known in the genus, they most likely belong to different species. The species group requires further systematic study based on further material. Pterygopolymorphism in Ploiaria turkestanica Although wing polymorphism is not rare in the family Reduviidae, it is exceptionally common in the subfamily Emesinae. In the cosmopolitan genus Ploiaria SCOPOLI, 1786, containing more than 120 described species, macropterous, brachypterous, micropterous and apterous specimens occur. However, de-
