Legs. Forecoxa slightly shorter than pronotum length, longer and wider than middle and hind coxae; forefemur widened, 3-4 × as long as wide, wider and slightly longer than middle femur, slightly wider and shorter than hind femur (Fig. 13G, H, N), segment I of hind tarsus twice longer than segment II; segment III slightly longer than segment II (Fig. 13O); claw with subapical tooth; middle row of tiles on unguitractor full (Fig. 13L). Genitalia. See species description.

Female. Similar to male. Genitalia. See species description.

Etymology.

The genus is named for its sparkling appearance, micans from Latin meaning sparkling, glittering. The genus is masculine.

Remarks.

Micanitropis belongs to Fulviini as its structure fits the diagnosis for this tribe, in particular, it has the prognathous head, the antenna shorter than the body, the body impunctate, and its labium is long, reaching or almost reaching the genitalia segment (Gorczyca 2000).

Micanitropis is similar to Peritropis Uhler, 1891, as they both have the moderately elevated calli, the carinate lateral margins of pronotum, the eyes elongate in lateral view and reaching gula, and the hemelytron, at least in some species, including type species P. saldaeformis Uhler, 1891, is covered with small tubercles (Moulds and Cassis 2006; Wolski and Henry 2012). Currently Peritropis includes ca. 90 species worldwide, with only the Australian and American fauna having been revised (Moulds and Cassis 2006; Wolski and Henry 2012). According to the previous works and personal observations, Peritropis differs from Micanitropis in the collar being indistinct, the vertex usually more or less carinate, the metathoracic scent gland evaporative area usually being reduced or at least its anterior angle being rounded, and the head, pronotum and pleura not being covered with rugosities, but instead with a net-like pattern of microsculpture. The anterior margin of pronotum of Peritropis is also often concave and angulate at sides, and the apical part of ductus seminis does not have the row of outgrowths along margin (Moulds and Cassis 2006; Wolski and Henry 2012).

As mentioned in the remarks for Callitropisca, this genus, Micanitropis, and Xenocylapidius share similar genitalic structures, with the apical part of the ductus seminis having two lobes, bearing a row of long outgrowths along outer margin. See comparison of Callitropisca and Micanitropis in the Remarks section for Callitropisca . Xenocylapidius and Micanitropis are similar in the head being longer than high in lateral view, the vertex flat (Fig. 13I; Wolski and Gorczyca 2014b: figs 9-15), and the tarsal segment I being longer than tarsal segments II and III each (Fig. 13O). However, Xenocylapidius differs from Micanitropis in the antennal segment I being longer than the vertex, the setae covering the dorsum are either dense and short or long and sparse, and the head, pronotum, and scutellum are not rugose or only slightly rugose (pers. obs.; Wolski and Gorczyca 2014b).
