Intergonocoxal area moderately long, with 2 indistinct lobes each with 4 long setae. Gonocoxa broad, longer than gonostylus, with sparse and fine setosity. Gonostylus ( Fig. 3A ) wide, roundish laterally, convex medially, slightly narrowed apically; with short and dense setosity apically, with straight and conical apical tooth, with 1 megaseta on apical, 1 on dorsal, 1 on ventral side of apical tooth, with 3 subapical megasetae very near apical tooth; slightly differentiated whip-lash seta on apical quarter of gonostylus. Tegmen ( Fig. 12A ) slightly shorter than wide, roundish and membraneous apically, straight and strongly sclerotized laterally, with long apodemes, and a large area of aedeagal teeth. Aedeagal apodeme rather short. BIN . Unknown. Discussion . Lycoriella ampla sp. n. has long antennae, a narrow eye bridge with one or two rows of facets, an extremely short maxillary palpus with a strongly deepened sensory pit (2 nd and 3 rd palpal segments are short and oval and together as long as 1 st segment), basally narrowed wings, a very short wing vein R1, and a small demarcated fore tibial organ. The intergonocoxal area has apically two small groups of only four or five closely placed setae, the medial side of the gonostylus is straight, with a relatively short whip-lash seta on its apical half, and a slender apical megaseta. These characters are shared with Lycoriella micria Mohrig & Menzel, 1990 . Lycoriella ampla differs from L. micria in having longer antennal flagellomeres, a strongly widened gonocoxa and gonostylus, apically roundish tegmen with straight sclerotized lateral sides, a nearly straight apical tooth, and a higher number of apical-subapical gonostylar megasetae (see the description). Lycoriella micria has a narrower gonocoxa and gonostylus with more widely placed and stronger subapical megasetae, a wider and straighter apex of the tegmen, more indistinct groups of setae in the intergonocoxal area, and a more strongly curved apical tooth of the gonostylus with only one apical and three to four subapical megasetae. The extremely voluminous gonostylus of L. ampla , with its extremely widened lateral side, resembles that of Bradysiopsis vittigera ( Zetterstedt, 1851 ) and the unusually sclerotized lateral sides of its tegmen, unknown in any other known species of Lycoriella , resemble those of Hemineurina riparia ( Holmgren, 1883 ) [see Figs 159 and 374 in Menzel & Mohrig (2000)]. Etymology . The name is Latin, ampla , widened, referring to the widened gonostylus of the male hypopygium.
