Diagnosis. M. maputuana   sp. n. is the Southern African sister species of M. omphalota ( Hampson, 1903)   (figs 19, 20, 54, 74) differing from that in the following features: the new species is somewhat larger in size (length of forewing and wingspan of M. omphalota   are 5–6 mm and 12–13 mm, respectively, while those of M. maputuana   are 6–8 mm and 13–16 mm, respectively), its forewing ground colour is much darker greyish brown with less prominent greyish orbicular stigma frequently fused with a darker, quadrangular medio-costal patch, while the forewing of M. omphalota   is much paler, rather whitish grey with sharply defined, more distinct blackish orbicular stigma.

The differences between the male genitalia of the two species are also well expressed: the robust, hook-shaped harpe of the new species is significantly smaller, with much shorter thorn-like apical section compared to that of M. omphalota   in addition, the curved claw-like cornutus of the aedeagus is significantly longer and more slender in the new species than in M. omphalota   , as well as in other members of the M. omphalota   species group ( M. omphalota euroetes Hacker, 2012   , M. denauxi Orhant, 2003   and M. mineti Hacker, 2012   ).

The new species’ female genitalia has somewhat longer apophyses and considerably longer sclerotized distal section of ductus bursae compared to those characters of M. omphalota   .

The closely related Mecothrix mineti   occurs sympatrically with the new species in Maputaland, however the two species are easily distinguishable by the following characters: M. maputuana   is considerably larger in size (length of forewing and wingspan of M. mineti   are 5–6 mm and 12–13 mm, respectively, while those of M. maputuana   are 6–8 mm and 13–16 mm, respectively), having conspicuously wider forewings and darker ground colour of fore- and hindwings compared to those of M. mineti   ; in addition, the new species has larger, somewhat less sharply defined orbicular stigma, often fused with a dark grey, quadrangular medio-costal patch, while the smaller orbicular stigma of M. mineti   is darker grey than that of M. maputuana   and only rarely fused with the rather pale costal patch. In the male genitalia, besides the above mentioned difference in the shape of the cornutus, further distinctive character is expressed by the configuration of the harpe, which is considerably slimmer, and less scurved in M. maputuana   than in M. mineti   . In the female genitalia the new species has significantly longer and thicker ductus bursae and somewhat longer pair of finger-like signum bursae compared to those characters of M. mineti   .

Description. Adult ( Figs 15–18 View FIGURES 1–16 View FIGURES 17–30 ). Forewing length 6–7 mm in males, 7–8 mm in females. Male antennae fasciculate with short rami, female antennae filiform. Head relatively large, frons and vertex whitish grey; compound eyes large, globular; palpi well developed, their length as width of head, gently arcuate, medially dilated, inner and dorsal surface bright white, lateral surface dark greyish brown. Thorax and abdomen uniformly pale grey in both sexes, somewhat darker in females. Intraspecific variability significant, expressed by the variable tone of the ground colour of wings, the thickness and definition of the elements of forewing pattern, especially the orbicular stigma, the costal patch and the postmedial line. Forewing short, moderately broad, rather quadrangular with rounded apex; forewing ground colour pale grey with some brownish sheen in males, considerably darker grey in females. Subbasal and basal lines deleted, antemedial line fine, blackish, interrupted, v-shaped; medial line shadow-like, pale brownish grey ending in a conspicuous, darker grey, relatively large quadrangular costal patch. Orbicular stigma well developed, rounded, consisted of raised, blackish scales, often fused with costal patch forming a dark dash-like patch in the costal half of forewing. Postmedial line fine, blackish, may be interrupted, rather wavy, conspicuously dilated and sharply defined in its ventral quarter. Subterminal line diffuse, shadow-like consisted of a series of somewhat darker greyish patches; terminal line shadow-like, interrupted, consisted of darker greyish squares; cilia pale brownish grey, somewhat lighter than terminal line. Hindwing pale ochreous brown in males, whitish grey in females, lacking any pattern in both sexes, distal section of veins covered with darker greyish scales in females, unicolorous in males; cilia creamy white in males, pale grey in females. Underside of wings unicolorous, lacking any pattern in both sexes.

Male genitalia ( Figs 52 View FIGURES 44–52 , 53 View FIGURES 53–61 ). Uncus absent; tuba analis wide, scaphium very long and thin, weakly sclerotized; tegumen short and broad, weakly sclerotized; juxta short and broad ovoidal; vinculum relatively short, very narrow, finger-like, apically rounded, possessing a pair of dense, extraordinarily long, easily removeable androconial hairtufts arising from a pocket-like lateral extension of vinculum; valva elongated, relatively broad, with more or less parallel distal and proximal margins, apically broadly rounded, with a narrow, short concavity between apex and tip of saccular process. Sacculus relatively broad at base, tapered medially, forming a narrow, slightly arcuate sclerotized band along the ventral margin of valva, apically with a short, slightly dilated, apically rounded, gently setose process. Harpe short, s-shaped, basally relatively narrow, apically pointed, claw-like with apex pointing posteriorly. Aedeagus relatively short and broad, strongly dilated at ostium ductus ejaculatorii, then gradually tapering, apically narrowly rounded, caecum rather short, apically slightly dilated; vesical armed with a large, curved, relatively slim, gradually tapering, apically pointed claw-like cornutus.

Female genitalia ( Figs 72, 73 View FIGURES 67–75 ). Ovipositor short and broad; papillae anales rectangular, with rounded angles; apophyses posteriores relatively long and thin, apophyses anteriores very short and thin. Eighth tergite relatively short and broad, its distal margin straight with a short, rounded medial process, proximal margin with a shallow, wide medial concavity. Ostium bursae moderately broad, narrow elliptical; ductus bursae conspicuously long, relatively broad, dilating proximally, dorso-ventrally flattened, folded in its distal third, strongly sclerotized in full length. Cervix bursae rather short, broadly rounded with a small sclerotized ring at the base of ductus seminalis. Corpus bursae more or less ovoidal, distal section narrower, proximal one broadly rounded; signum bursae consisted of a pair of relatively long, finger-like processi, distal one broad-quadrangular, proximal one narrow, apically rounded.
