Integrative taxonomy reveals first record of Loxosceles rufescens (Dufour, 1820) (Araneae, Sicariidae) in the Philippines

The spider family Sicariidae Keyserling, 1880 represented by the synanthropic Mediterranean recluse spider, Loxosceles rufescens (Dufour, 1820), is reported in the Philippines for the first time, based on morphological and molecular data. The introduced spider was observed in a small cave (Kamantigue Cave) in Lobo, Batangas Province. Considering the medical importance of this spider, the proximity of its habitat to human habitation and tourist sites poses a potential public health concern.This study reports on the first record of the family Sicariidae in the Philippines and the fourth recorded occurrence of L. rufescens in Southeast Asia.
