Montina nigripes Stål, 1859

( Fig. 35 )

Montina nigripes Stål, 1859: 197 (new species).

Montina (Montina) nigripes: STÂL (1872) : 73 (checklist, new generic placement, Montina as subgenus).

Montina nigripes: LETHIERRY & SEVERIN (1896) : 195 (catalog); MALDONADO (1990): 235 (catalog).

Type locality. Brazil, Bahia.

Type material. HOLOTYPE: [ BRAZIL]: 1♀, (green label) “ Bahia Gomez ” / “ nigripes Stål ” / (red label) Typus / 2561 ( ZMHB).

Diagnosis. General coloration reddish brown, with head, legs, and scutellum black ( Fig. 35B ); apex of posterolateral process of the pronotum sharp, almost spinelike; membrane translucent; margin of connexivum slightly lobed, more so in segments 4 and 5, darkened with narrow yellow margin ( Fig. 35A ).

Differential diagnosis. Montina nigripes is similar to M. scutellaris and M. calarca sp. nov. due to their reddish and black overall coloration. Montina nigripes can be differentiated from M. scutellaris because it has a general dark red coloration, having the proximal portion of the hemelytron and the posterior margin of the pronotum reddish ( Fig. 35B ), and the connexival margin has a pale-yellow band ( Fig. 35A ), whereas in M. scutellaris the overall coloration is orange, the proximal portion of the hemelytron and posterior margin of the pronotum is darkened ( Figs 19 , 37 ), and the connexival margin has red areas larger posteriorly, in M. scutellaris ( Figs 19A, D ). Montina nigripes can easily be distinguished from M. calarca sp. nov. because of the sharp apex of the pronotal posterolateral process ( Fig. 35B ), in contrast with the obtuse apex found in M. calarca sp. nov. ( Figs 5B, D ), and the presence of a pale-yellow band on the margin of the connexivum ( Fig. 35A ) in contrast to a red band in M. calarca sp. nov. ( Figs 5A, C ).

Distribution. Only known from Brazil ( STÂL 1859). The record from Panama (CHAMPION 1899, MALDONADO 1990) is a misidentification of M. scutellaris (see above).

Remark on type. STÂL (1859) indicated that he examined a single female from Bahia, Brazil. At ZMHB there is a single specimen bearing a label from “ Bahia ”, thus we interpret it as the holotype.
