Comparative diagnosis
This new species is similar to D. (G.) grandis (Fahringer, 1930) known only from Spain, but differs from it by the mediocubital vein (M+CU1) of fore wing distinctly curved in apical half (nearly straight in D. grandis), vertex densely irregularly transversely striate with dense and numerous rugosity (mainly granulate in D. grandis), radial vein (r) arising behind middle of pterostigma (from middle in D. grandis), brachial (subdiscal) cell closed distally distinctly before recurrent (m-cu) vein (weakly before vein in D. grandis), second radiomedial (submarginal) cell not narrowed distally (distinctly narrowed in D. grandis) and hind basitarsus short and thick (long and slender in D. grandis).
Etymology
Name derived from a combination of ‘ maculis ’ (Latin for ‘spotted’) and ‘ pennis ’ (Latin for ‘plumage’) because of the spotted colouration of the fore wing.
