Abstract:
The transmission of cutaneous leishmaniasis (CL) is of public health concern in Sri
Lanka. The parasite Leishmania donovani is reported to be the causative agent for CL in Sri
Lanka. However there is no report on the vector of CL in the country. Phlebotomus argentipes
sensu lato is the well known vector of L. donovani which causes visceral leishmaniasis (VL)
in the nearby South India. The taxon Ph. argentipes previously reported to occur as a species
complex comprising of two morphospecies namely A and B. The taxonomy of the Argentipes
complex was reassessed recently and reported to have three species viz. Phlebotomus
glaucus, Ph. argentipes sensu stricto and Ph. annandalei. A study was carried out in Jaffna
mainland, where three CL patients have been recorded, and two associated islands in northern
Sri Lanka to record the presence of the members of the Argentipes complex. Sandflies were
collected using human landing and cattle baited collections. Collected samples were analyzed
based on reported morphometric and meristic characteristics. The study revealed the presence
of all three members of the complex in which Ph. glaucus and Ph. argentipes s.s. are reported
for the first time in Sri Lanka.
