Thaumastomiris piceatus – Stonedahl 1988: 96 (figs 93, 99, redescr.). Diagnosis Recognized by the following characters: total length 5.1–5.4; dorsum reddish with large diffuse brown spot on apical half of clavus and medioapical area of corium; left wall of genital capsule with two very long and thin subapical spines ( Stonedahl 1988 : fig. 99a); aedeagus with single-coned, spinelike subapical sclerotized process ( Stonedahl 1988 : fig. 99e). Material examined Lectotype INDIA • ♂ ; Ganges delta , Sorabkatti ; 14 Dec. 1909 ; Jenkins leg.; at light ; NHM . Paralectotype INDIA • 1 ♂ ; Ganges delta, Khulna distr. , Gurhhalee , 8 Dec. 1909 ; Jenkins leg.; at light; NHM . Other material BURMA • 1 ♀ ; Rangoon ; Mar. 1927 ; E.J. Meggitt leg.; USNM . Distribution Burma , Pakistan , and northern India ( Stonedahl 1988 ) . Remarks Phylogenetic analysis of the genus ( Stonedahl 1988 ) resolved this species as a sister taxon to Th. sanguinalis , which differs from Th. piceatus in having uniformly reddish dorsum, short subapical spines on the left wall of genital capsule ( Stonedahl 1988 : fig. 100a), and twin-coned sclerotized process of the aedeagus ( Stonedahl 1988 : fig. 100e). Thaumastomiris piceatus is similar to Th. discoidalis (New Guinea ) in the body size and coloration, particularly in the presence of brown medial spot on hemelytron, but the latter species may be distinguished by the antennal segment II longer than width of head and the presence of single spine on the left wall of the genital capsule.
