Abstract

During a recent survey of the insect fauna of the mangroves of the San Vicente Mangrove Forest
Association (SAVIMA) Bohol, Philippines, many Diptera specimens were collected. They were pre-sorted into
putative species (3% threshold) using COI sequences obtained via next-generation-sequencing (“NGS barcodes”:
313bp). The sequences were then compared to a database with sequences for more than 15,000 Southeast Asian
dolichopodid specimens belonging to >250 species. Sequences for two putative species were found to be new.
Morphological study revealed that these species are new to science. Based on the presence of peculiar ventral
bristles on the fore tibia and typical male terminalia, both belong to Thinophilus and are here newly described as
Thinophilus lungosetole Ramos & Grootaert sp. nov. and Thinophilus ronazeli Ramos & Grootaert sp. nov. We
provide extended diagnoses that are illustrated with stacked habitus photos, figures of the male terminalia and NGS
barcodes. A checklist of all Dolichopodidae recorded in the Philippines is provided.
