Diagnosis.
From s.g.
Roscidotoga
Hoare
, s.g.
Simplimorpha
differs by the lack of shiny markings on forewing, the presence of two distal veins on forewing (three in
Roscidotoga
), valva with a ventral lobe (without a lobe in
Roscidotoga
), and the slender anterior apophyses in the female genitalia (anterior apophyses very wide in
Roscidotoga
). The feeding preference on
Anacardiaceae
,
Sapindales
(Malvids / Eurosids II), and the South African-Mediterranean distribution make
Simplimorpha
distinctive compared with s.g.
Roscidotoga
that occurs in
Australia
and feeds on
Cunoniaceae
and
Elaeocarpaceae
,
Oxalidales
(Eurosids I / Fabids).
From
Myrtinepticula
subgen. nov.
, s.g.
Simplimorpha
differs by the absence of strong purple or blue iridescence of adult scaling, the presence of two distal veins (four in
Myrtinepticula
), the absence of anal loop of forewing, presence of two distal veins of hindwing (three in
Myrtinepticula
), presence of transverse bar of transtilla (usually absent in
Myrtinepticula
), wide phallus (slender in
Myrtinepticula
), small corpus bursae (greatly reduced in
Myrtinepticula
), and the slender anterior apophyses (very broad in
Myrtinepticula
).
Simplimorpha
is distinctive because it feeds on
Anacardiaceae (Sapindales)
and is distributed in Africa and the Mediterranean in contrast to
Myrtinepticula
subgen. nov.
that feeds on
Myrtaceae (Myrtales)
and is distributed in South America.
Description. Adults with collar comprised of piliform or lamellar scales. Forewing with distinctive pale scales (
Figs. 63, 64
). Forewing venation (
Figs. 52–54
) with four veins on Rs+M stem, or two veins distally. Male genitalia: tegumen wide, truncate, laterally setosae (
Figs. 1, 2
); vinculum large, rounded (
Figs. 7, 8
); valva slender, with a basal part little or greatly extended in the shape of ventral lobe (
Figs. 13, 14
); transtilla with a transverse bar (1) weakly chitinized uncus is preserved in
S. nielseni
, see further for
Figs. 97–99

Remarks: yet although the wing venation in general is valuable it is not without its limitations: independent losses are likely; being extreme tiny moths, the venation can be rather easily got reduced even in cases of related species (Figs. 53, 54) or, occassionally, within same species (Puplesis & Robinson 2000). Note that the morphological structures are drawn in different scales.
