Leptogaster piliensis (Oldroyd, 1972) , comb. n.

Euscelidia piliensis Oldroyd, 1972: 215 ; Joseph & Parui 1983: 278.

Type material - The holotype of undeterminable gender is labelled ‘P. I.: LUZON CAMARINES SUR Mt. Isarog, Pili 600 m, 15.IV.1965 / H. M. Torrevillas Collector BISHOP / 77 / Not same as that figured as setifer antennae 3 shape of scutum (handwritten) / Euscelidia piliensis sp. n det. H. Oldroyd 1971 HOLOTYPE (handwritten except for ‘det. H. Oldroyd 19’) / Bishop Museum Holotype No. No. 9668 (red label with black margin) / Leptogaster piliensis (Oldroyd, 1972) det. T. Dikow 2001’. The specimen is directly mounted, is in poor condition (right pped, all left tarsi, and abdomen broken, thorax cracked), and is deposited in the BPBM.

A ^ paratype is labelled ‘ P. I.: Luzon CAMARINES SUR Mt. Isarog, Pili 600 m, 15.IV.1965 / H. M. Torrevillas Collector BISHOP / Leptogaster piliensis (Oldroyd, 1972) det. T. Dikow 2001’. The specimen is double mounted, is in good condition, and is deposited in the BMNH .

Type locality: Philippines, Luzon Island , Mount Isarog National Park, Mt. Isarog (600 m), 13 39'N 123 22'E .

Remarks: The species does not belong to Euscelidia . There is a minute vertical cylindrical structure on the pronotum that is similar to the ppro peg found in Euscelidia , but I consider this not homologous with the feature described and illustrated above ( Fig. 3 ). Oldroyd’s drawing (1972: 213, Fig. 9 ) of the ơ terminalia shows also a shape never found in Euscelidia (sur with two equally developed lobes that are separated proximally).
