Hemilomecopterus alienus Martins & Galileo, 2004: 42 View in CoL .

Remarks. – Hemilomecopterus alienus was described based on a single female from Colombia (Amazonas). Galileo & Martins (2005) recorded the species from Ecuador (Napo) based on two males. The shape of the head, with the genae very elongated and frons distinctly oblique, makes it easy to recognize the species.

According to Martins & Galileo (2004) (translated): “Head black, except macula on occipital region, on inferior region of frons, and genae which are reddish.” In the female from Brazil,the dorsal surface of the head is entirely black, frontal area of the genae is mostly brown, the apex of the genae is brownish,and the inferior region of the frons and the wide central area of the postclypeus are orangish brown. Still according to them (translated): “Antennae black” (in the female from Brazil, the dorsal apex of the scape is brown, the apical half of the dorsal surface and most of the sides of the apical third are yellowish brown, apical quarter of antennomere III is brown, antennomere IV 20. Ventral habitus. 21. Lateral habitus. 22. Head, lateral view. 23. Head, frontal view.

andbasalhalf of Vare brownish, and the apical half of antennomere V and antennomeres VI-VIII are dark brown); “Elytra with the basal half orangish yellow, except the humeri which are black; with transverse black band after middle, followed by another transverse yellowish band, covered with dense pubescence of same color; and reddish-brown apical fifth, covered with yellowish pubescence” (in the female from Brazil, the dark central band is dark brown, starting before middle of the elytra; the anterior region is yellowish brown; there is a dark longitudinal band from humerus to the transverse central band, not reaching epipleural margin, black basally, gradually browner on its apical region; the sides of area from the transverse dark-brown band to near apex is blackish; remaining apical half is orangish brown except the brown punctures; and the pubescence is yellowish-white, except sparser and brown pubescence on dark-brown central area); “Fore- and middle legs yellowish” (in the female from Brazil, the dorsal surface of profemora is brown basally and dorsal surface of protibiae is dark brown on wide central area; mesofemora are blackish except yellowish-brown apex of dorsal surface and sides, this area longer on sides, and yellowish-brown apical third of ventral surface; and mesotibiae is blackish basally, and most dark brown on remaining surface); “Metafemora black, except the ventral surface” (in the female from Brazil, only the apical third of the ventral surface is yellowish-brown); “Mesoventrite black with the mesoventral process yellowish” (in the female from Brazil, the mesoventral process is brown on sides of anterior half and orangish brown on remaining surface); “Mesepimeron, metanepisternum, and sides of metaventrite black” (in the female from Brazil, the mesepimeron is brownish, the metanepisternum and sides of metaventrite are reddish brown); “abdominal ventrites 1 to 3 yellowish, 4 and 5 brown (in the female from Brazil, the sides of abdominal ventrite 4 is brownish basally, gradually, dark brown toward apex, and 5 is entirely dark brown). Furthermore, in the description of the genus it was reported that the elytra in female are 3.6 times longer than the humeral width, while in the female from Brazil, the elytra are 3.2 times longer than the humeral width.
