Description
TABLE 2. Diagnostic characters for X. lichneuta and X. melanopsamma on the base of female and male genitalia.
| No | Diagnostic character\ species | X. lichneuta | X. melanopsamma |
|---|---|---|---|
| Female genitalia | |||
| 1 | distance between anterior edge of sterigma and posterior edge of 7th segment | relatively short, 7.6 times shorter than papillae anales | relatively long, 2.5 times shorter than papillae anales |
| 2 | shape of posterior edge of 7th sternite | rounded concave, with distinct lateral triangular projections | almost straight, with faintly distinguishable lateral projections |
| 3 | shape of sterigma | transversely oval with distinct anterior margin | more or less angular, with a weakly defined anterior edge |
| 4 | 7th sternite | with relatively wide longitudinal zone almost lacking microsetae in the middle and sclerotised lateral sides | with close longitudinal lines of dense microsetae in the middle and weak sclerotised lateral sides |
| 5 | plate between base of papillae anales | as equilateral triangle | as longitudinally elongated triangle |
| Male genitalia | |||
| 6 | length of harpa | reaches 9/10 of valva length | slightly exceeds 3/5 of valva length |
| 7 | row of strong thorns on apical part of harpa | semioval with equal dorsal and ventral parts (Fig. 8) | arched, with longer part along ventral margin of harpa (Fig. 12) |
| 3 | thorns on the apical part of harpa | smaller | larger, especially along ventral margin of harpa |
| 4 | shape of valva | smoothly widened from base towards 3/5 (Fig. 7) | smoothly widened from base towards 1/3, further parallel-sided towards 2/3 (Fig. 11) |
