Diagnosis

The elongate gonostylus of simple shape is not compressed at the apex, which is rounded and covered with dense microtrichia (↓ 1, Fig. 14A View Fig ). The gonocoxites are peculiar for both the membranous portions ventroposteriorly, whose outline resembles a stair (↓ 2, Fig. 14A View Fig ), and the ventral emargination, which is large, somewhat rectangular and vaguely delineated at the base (↓ 3, Fig. 14A View Fig ). The ninth tergite has an almost truncate, strongly sclerotized posterior edge (↓ 4, Fig. 14B View Fig ), which is a unique feature in Glemparon , and on the inside numerous small tubercles in indistinct rows. The tegmen is provided with a pair of sclerotized, serrate points (↓ 5, Fig. 14C View Fig ) and, at the points’ bases, sclerotized processes each consisting of two curved teeth (↓ 6, Fig. 14C View Fig ).

Etymology

The specific epithet refers to Lake Rotoiti in the north of New Zealand’s South Island, where the holotype was collected.
