Description (male). For more detailed description, see Gordon & Canepari (2008) and Corrêa, Santos & Almeida (2011). Length: 6.58, width: 5.58 mm. Similar to female in all aspects except for elytral spots larger and almost joined ( Fig. 4 A, B). Abdomen yellowish with yellow pubescence ( Fig. 4 C). Genitalia with basal lobe asymmetrical, half length of parameres, apex slightly obliquely truncated; parameres straight, apex rounded with long setae ( Fig. 4 D, E); sipho slender, long, strongly curved; siphonal capsule with inner and outer arm developed; apex sinuate ( Fig. 4 F–H).

Geographical Distribution. French Guiana (Cayenne, Montagne des Chevaux, Bélvédère de Saül and Réserve Naturelle des Nouragues New records) and Brazil (AM, Itacoatiara) ( Fig. 10 ).

Remarks. Menoscelis insignis differs widely from all other species of the genus in its color pattern and male genitalia. The shape of the mentum and legs, 11-segmented antennae, and the slightly curved postcoxal line of M. insignis resemble M. saginata ( Figs 5 A–B, D–E, G).
