Prolygus alboscutellatus Carvalho, 1987

( Figs 43–44 )

Prolygus alboscutellatus Carvalho, 1987: 140 (original description).

Material examined. INDONESIA: SUMATRA: Brastagi, North of Toba Lake, 3.18, 98.50, 1,400 m, UV light trap, 8 Dec 1989, T. Yasunaga, 1 ♀ ( AMNH _PBI 00380625) ( TYCN). PHILIPPINES: NEGROS ISLAND: Camp Lookout, Dumaguete, 22 May 1961, Schneirla & Reyes, 1 ♁ (00110770) ( AMNH).

Distribution. Indonesia (Sumatra) (new record), Papua New Guinea ( CARVALHO 1987), Philippines (Negros) (new record).

Comments. A female specimen ( Fig. 43 ) from N. Sumatra and a male ( Fig. 44 ) from Negros Island could belong to this taxon, which is now assumed to be a close relative of P. nigriclavus , based on similarities in basic color pattern (yellow-brown dorsum, yellow pronotum sometimes with dark, posterior fascia and more or less darkened clavus), elongate median process at apex of left paramere hypophysis, and presence of a single lobal-sclerite on the endosoma. But the scutellum of P. alboscutellatus sometimes has a large, black, triangular mark in the middle, differing from that illustrated by CARVALHO (1987).
