obscura (Arma) Dallas 1851: 100. [ Fig. 130 ]

Original data: “ ♀ ”; “a. Brazil. Presented by E. Doubleday, Esq.” [syntype (s)]

LECTOTYPE ♀ (designated by Thomas 1992: 89): purple-margined lectotype disc; red-margined type disc; “ Brazil / 45 67; “20. ARMA OBSCURA ,”; “a”; “NHMUK 010592329”. Fifth right antennomere, third to fifth left antennomere, and right anterior and posterior legs missing; genital plates disjointed ( Fig. 130 ).

Current status: Podisus nigrispinus ( Dallas, 1851) (synonymised by Thomas 1992: 88).

Note: Thomas (1992: 89) explained: “The type of Arma obscura , a female, was located in the British Museum (Natural History). It is labeled: (a) “Type,” (b) “ Brazil,” (c) “a,” (d) “20. Arma obscura .”” From Dallas’s original description, we do not know whether Dallas had one or more specimens, only the sex: female. Walker (1867a: 137) listed one specimen from the same provenance and we have found only one female specimen in the collection but cannot be sure it was the only one Dallas had. By giving its labels data and calling the specimen “the type”, Thomas designated it as the lectotype by inference of “the type” ( ICZN 1999: Art. 74.6).
