Type material.

Holotype: male (IZCAS), Mahawafa Hill (6°55.92'N, 80°14.68'E, elevation 38 m), Mahawafa Village, Avissawella Town, Maniyangama, Colombo District, Western Province, Sri Lanka, 26 September 2014, S. Kosala leg. Paratype: 1 female (IZCAS), same data as holotype.

Etymology.

The specific name refers to the type locality; noun in apposition.

Diagnosis.

Males of M. colombo sp. nov. resemble M. oryzae, but can be distinguished by a distinct cymbial protrusion approx. 1/2 length of bulb (Fig. 5D) (vs. inconspicuous cymbial protrusion approx. 1/3 the length of bulb), conductor bifurcate and distinctly shorter than embolus (Fid. 5B) (vs. conductor not bifurcate and almost similar length with embolus). Females can be distinguished by having a pair of elongated spermathecae concaving posteriorly (Fig. 6A).

Clypeus brownish, with dark brown marks medially. Labium and sternum dark brown. Abdomen slightly elongated, brownish, with dark brown marks dorsally and ventrally (Fig. 6E).
