Pantophthalmus comptus Enderlein, 1912 ( Figure 1 )

Pantophthalmus comptus Enderlein, 1912: 107 , 117. Holotype: female (Staatlichen Naturhistorischen Sammlungen Dresden, Germany, STM, as STMD in PAPAVERO 2009). Type locality: "South America. [For nomenclatural history, see PAPAVERO (2009)].

Diagnosis. Female (see BARROS et al. 2019). Male: body mostly brownish; scutal bands not well developed, no dark spot at transverse suture level; scutum homogenously brown, except for a weak pair of silver pruinescence over the posterior portion of the scutum medially; scutum markedly covered by medium-sized yellowish setae; scutellum dark brown on its apical half as shown in VAL (1976); pleuron dark brown; with no ventral spine on hind femur.

Material examined. BRAZIL, Maranhão, REBIO - Res. Biol. Gurupi [ Reserva Biológica do Gurupi ], 03°14'05"S 46°41'83"W, armadilha de Malaise, 07-15.i.2011, F. Limeira-de-Oliveira & D.W.A. Marques (1 ♀, CZMA); same data, except: 03°14′01″S 46°40′52″W, armadilha luminosa, 03-07.v.2011, M.M. Abreu & J.A. Silva, cols. (1 ♂, CZMA) .

Distribution. Belize, Colombia, Guyana, Suriname, French Guiana, Peru, Brazil (states of Roraima, Amazonas, Pará, and Maranhão [new record]) ( BARROS et al. 2019).

Comments. Similarly to the female, the male has wings with a yellowish base and an abdomen mostly orangish, with lateral margins dark brown with white spots ( Figure 1A, B ). The color intensity of the legs in the male is not as dark as in the female from Roraima ( BARROS et al. 2019), but the pattern is the same, with all tarsomeres lighter, particularly the hind tarsomeres, which are nearly yellow ( Figure 1A ). VAL (1976) provided illustrations of the male terminalia and here, we complement her efforts with the first digital images of the male terminalia of P. comptus ( Figure 1 C-I).
