Pantophthalmus kerteszianus ( Enderlein, 1914) View in CoL Figs. 1 View Figure 1 , 2 View Figure 2 , 4 View Figure 4

Acanthomera kertéziana Enderlein, 1914: 578 . Lectotype: female (MfN, examined by photo; according to Val, 1976, the two females syntypes should be in Warsaw and Budapest, one in each collection, but no specimen was found in Warsaw; a female labeled as the type was found in the Berlin collection and designated as lectotype, see Val, 1976: 79). Type locality: Peru, Mariscal Cáceres, Juanjui. [For nomenclatural history, see Papavero (2009: 3), no changes are proposed here].

Diagnosis: Female – Body predominantly brownish to black ( Fig. 1A View Figure 1 ). Frons and antenna orangish-brown ( Fig. 1B, C View Figure 1 ). Face with a very prominent beak ( Fig. 1C View Figure 1 ). Thorax covered with grayish pruinosity and three dark brown longitudinal bands; lateral bands thicker and almost parallel, medial band narrower than lateral bands and interrupted near the posterior margin of scutum ( Fig. 1A View Figure 1 ). Wing with yellowish-brown base, most visible at the level of humeral vein ( Fig. 1D View Figure 1 ). Legs reddish-brown to dark brown, except all tarsomeres 1-2 yellow ( Fig. 1A View Figure 1 ), ventral spine of hind femur reduced in size ( Fig. 1E View Figure 1 ). Abdomen black with small white spots on lateral margins of tergites 2 and 3.

Materialexamined: Brazil,TO[Tocantins], Porto Nacional, Jardim Querido [-10.704158°, -48.400074°], Casa , x.2018, coleta manual, Gaizer, F. leg. (1 ♀ CEUFT 005849 ) ; idem, Setor Vila Operária [-10.725103°,-48.385207°], 25.iii.2021, Silva , R.M. leg. (1 ♀ CEUFT 005850 ) ; idem, iv.2014, Krolow , T.K. leg. (1 ♀ CEUFT 005851 ) .

Comments: Val (1976: 79, fig. 102, female) mentioned the presence of a dark triangular spot on the posterior region of the scutum.In the examined specimens,the triangular mark is small, barely visible, similar to that observed in the lectotype and additional female deposited in Berlin ( Fig. 2 View Figure 2 ). In addition, the studied specimens have considerable variation in size, the smallest measures

19 mm and the largest, 26 mm. This size difference was found in Thunberg′s collection in UUZM, but labeled also noted by Carrera & d′Andretta (1957), who men- from Brazil; presumed lost according to Papavero, tioned that the body length of this species varied be- 2009:5). Type locality:Lesser Antilles, Saint Barthélemy tween 20 and 35 mm. (Forsström). [For nomenclatural history, see Papavero

(2009: 3), no changes are proposed here].

Figs. 2 View Figure 2 , 3 View Figure 3 , 4 View Figure 4

Pantophthalmus tabaninus Thunberg,1819 :vii,pl.,figs.1-4. Type: 1 specimen, likely male as stated by Thunberg (UUZM, see Wallin & Wallin, 2001: 27; according to Val, 1976 only one male specimen,not labeled as type, was Diagnosis: Female – Body predominantly brown to black ( Fig. 3A View Figure 3 ). Frons yellow ( Fig. 3A, B View Figure 3 ). Face with a slightly prominent beak ( Fig. 3B, C View Figure 3 ). Antenna dark brown, covered with yellowish pruinosity,flagellum with the first two flagellomeres wider than the others, last flagellomere tapering towards apex, with an orange tip ( Fig. 3D View Figure 3 ). Thorax predominantly brown with a wide yellowish longitudinal median stripe. ( Fig. 3A View Figure 3 ). Wing with brown base ( Fig. 3E View Figure 3 ). Legs reddish brown to dark brown, hind femur without ventral spine ( Fig. 3F View Figure 3 ). Abdomen black with small white spots on lateral margins of tergites 2 and 3.

Material examined: Brazil, TO [Tocantins], Paraíso [-10.201604°, -48.884114°], Aneliese, A.F. leg. (1 ♀ CEUFT 005852 ) ; idem, Colinas do Tocantins [-8.059549°, -48.477156°], 07.v.2013, coleta manual, Nascimento, W.P.L. leg. (1 ♀ CEUFT 005853 ) .

Comments: The beak on the face of one examined specimen is dented, giving the impression that the structure is excavated. In the illustration provided by Val (1976: 121, fig.80,female) of P.tabaninus , it is possible to verify that the beak,although not very prominent,does not have a recess.
