Cechetra inconspicua  is the most divergent species in the genus in terms of its COIAbout COI mtDNA (COI-5P “barcode region”: Fig. 16View FIGURE 16, 40, Table 2). In habitus, it is closest to C. lineosa  and C. subangustata  . Cechetra inconspicua  differs from C. lineosa  in having entirely white antennae in males and white or dull pinkish ones in females ( Fig. 41View FIGURE 41); in males of C. lineosa  , they are brownish, pinkish or greyish basally. In comparison with C. lineosa  , in most specimens of C. inconspicua  the first diagonal line of the forewing upperside is wider and the distance between the first and second lines is greater than that between the second and the third. The median thoracic pale band of C. inconspicua  is divided longitudinally by a thin brown line, whereas in C. lineosa  this line is absent, weak or dark green. The colours are less bright than in C. lineosa  , C. scotti  and C. bryki  , making specimens of C. inconspicua  look like discoloured C. lineosa  or C. subangustata  . Except for the colour of antennae, all these characters work well only for fresh or well-preserved specimens. The female is similar to the male but larger.

The male genitalia ( Fig. 39View FIGURE 39) differ from those of C. bryki  , C. lineosa  and C. scotti  in the basal section of the harpe being more massive with a curved and less elongate sclerotized process; the phallus armature has a very small denticulate plate with smaller and more numerous uniform teeth.

One mtDNA haplotype of C. inconspicua  is shown in Fig. 40. The translated polypeptide sequence differs from other Cechetra  species in one non-synonymic amino acid substitution.

C. inconspicua  has been found in Northern Borneo (Sabah, Trusmadi Mt.) and Sumatra at altitudes of about 1000 m where this species appears to be rather common, so most records of C. lineosa  from those islands are probably attributable to C. inconspicua  . The moth illustrated in Holloway (1987) as C. lineosa  is actually C. inconspicua  but we were unable to locate that specimen in the NHMUKAbout NHMUK. In Sumatra, C. inconspicua  is sympatric with C. lineosa  and C. subangustata  ; in peninsular Malaysia and Borneo, it flies with C. lineosa  . We have no examples of C. subangustata  from Borneo.

The larval hostplants of C. inconspicua  are unknown. Genetically, this species is quite distant from C. lineosa  , C. scotti  and C. bryki  , so the hostplants of C. inconspicua  may be different from those of these species.

Etymology. The name refers to the long-overlooked existence of this species.
