Morphological variations were observed in Phlebotomus argentipes, the vector for visceral leishmaniasis reported from the endemic states of Bihar, West Bengal and Uttar Pradesh. The taxonomic features distinguishing vector and nonvector species of P. argentipes were relative length of ascoid and antennal segment IV. Three morphotypes were characterized as <0.4, = 0.4 and >0.4 respectively. Other characteristics of wing width, wing length, eye, style, antennal segment III, IV, V was found statistically significant (p<0.05) and eleven other morphological measurements were not significant. This study suggests three different morphotypes of P. argentipes in these three endemic states. The genetic and reproductive isolation among such morphotypes will establish the variability in further studies.
在比哈尔邦、西孟加拉邦和北方邦的地方病流行区报告的内脏利什曼病传播媒介银足白蛉中观察到形态变异。区分银足白蛉传播媒介和非传播媒介种类的分类学特征是Ascoid和触角第四节的相对长度。三种形态型分别被表征为<0.4、= 0.4和>0.4。发现翅宽、翅长、眼睛、尾器、触角第三节、第四节、第五节的其他特征具有统计学意义（p<0.05），而其他十一项形态学测量结果不具有统计学意义。本研究表明，在这三个地方病流行区存在三种不同形态型的银足白蛉。这些形态型之间的遗传和生殖隔离将在进一步研究中确定其变异性。
