Diagnostic characters

Maxilla with numerous cuspules arranged in a triangular area ( Figs 202–204 View Figs 202–210 ). PMS medium-sized to large. Apical segment of PLS elongate and considerably longer than in other Raveniola spp. ( Figs 555– 558 View Figs 555–564 cf. Figs 559–618 View Figs 555–564 View Figs 565–574 View Figs 575–583 View Figs 584–592 View Figs 593–601 View Figs 602–610 View Figs 611–618 ). Males: tibiae and metatarsi I–II without modified hairs ( Figs 256, 258, 260 View Figs 256–264 , 290 View Figs 290–309 ); cymbium moderately short (as in Figs 349–351 View Figs 349–363 ); embolus broadly tipped, always with well-developed subapical keel ( Figs 379–384 View Figs 379–388 , 466–468 View Figs 466–474 ).
