Distribution. Philippines (Luzon, Visayas, Mindanao)

Remarks. Externally similar to L. irrorata . Phallobase of male genitalia is distinctly longer than parameres. The species is well represented in the northern part of the Philippines especially in Central Luzon and least represented in the southern part particularly in the Mindanao region. It is least represented in the eastern coasts wherein majority of the specimens collected in the Samar and Leyte areas are L. irrorata . Distribution was also based on several museum collections deposited locally and internationally from 1911–2010 ( Fig. 41 ). The specimens examined match the digital photographs of Ernst Brenske specimens ( Fig. 42) from the ZMHB (provided by Dr. Joachim Willers) and Burmeister’s syntypes ( Fig. 43) from the MLU (provided by Dr. Karla Schneider).
