The specimens of the

series vary in dorsal body colouration: specimens from drying up stream are generally paler (ochreous) than specimens from Moka River. The highest variability is however in elytral striation: in some specimens short strioles present between suture and stria 1, suggesting the present of 
<normalizedToken originalValue="“true”">&quot;true&quot;</normalizedToken>
stria 1, which is vanished in all studied specimens (thus, the first visible stria is actually stria 2); in addition, strioles presenting in basal third between striae 9 and 10 may confluent into distinct stria in some specimens. On the other hand, all even striae have tendency for reduction, they are often fragmented, persisting only as a few longitudinal strioles or missing completely; in the extreme, only four elytral striae (stria 1, 3, 5, 7) are well preserved on disc with striae 9 and 10 preserved as short strioles (Fig.
