CF235683DA285A4998C34DEC536A0F7A.taxon	etymology	Etymology. The specific epithet glaisteri, a noun in the genitive case, is given in honor of Alena Glaister of Monash University, VIC, who devised a successful method of rearing Australian larval elmids to adults, thereby enabling their association. She published an extensively illustrated identification guide to the larval Elmidae of Australia with keys and descriptive notes on taxonomy, distribution, and habitat. Few elmid researchers have attempted such work, and none have produced larval keys covering so many taxa.	en	Barr, Cheryl B., Shepard, William D.

Disc with 10 punctate striae; punctures small and spaced <1 diameter apart, stronger anteriorly, fainter posteriorly; accessory basal stria between striae 1 and 2 long; stria 3 ending before posterior margin, striae 4 and 5 joining and ending just before posterior margin. Metathoracic wings: Macropterous. Prosternum: Very short anterior to procoxae, margined; prosternal process very setose, moderately narrow, 3 x longer than wide, with a distinct median longitudinal carina, apex rounded. Mesoventrite: Short, wide; disc concave between mesocoxae, with a deep mesoventral cavity to receive prosternal process; covered with short yellow setae. Metaventrite: Broadly rectangular; with a wide, circular, median depression covering posterior 3 / 4; discrimen as long as median depression; metakatepisternal suture present; disc heavily punctate, punctures small and often contiguous; disc covered with short, dense, yellow setae. Legs: Of different lengths, fore leg shortest, hind leg longest; each leg with femur shorter than tibia; mesotibia narrower than pro- and metatibia; tarsus with tarsomere 5 slightly longer than tarsomeres 1 - 4 combined; claws large, simple, acute. Coxae black, metacoxae deeply sulcate; femora yellow-brown or light red-brown each with dorsal surfaces and apical 1 / 3 black; tibiae black; mesotibiae with posterior surfaces flat, glabrous, shiny; metatibiae weakly arcuate; tarsi black. Abdomen: Five convex ventrites, each with a shallow depression near lateral margin; ventrite 1 with margined, broadly triangular, intercoxal projection; ventrites 2 - 4 widely rectangular, with lateral margins each produced to form a small lobe of varying size, those of ventrites 3 and 4 largest, which clasps the epipleuron; ventrite 5 with lateral margins evenly curved with broadly rounded apex. Ventrites covered with shallow, often contiguous, punctures, and semi-erect and recumbent yellow setae. Aedeagus: Mostly well-sclerotized; short, broad, widest at apex of phallobase; phallobase longer than parameres, parameres slightly shorter than penis; phallobase open dorsally (Fig. 42). In dorsal view (Fig. 42 A), parameres broad at base, abruptly digitate at apices; medial margin darkly sclerotized at basal 2 / 3 due to folding of the margin ventrally, inner surface flat against penis; medial margin weakly divergent at basal 1 / 2, arcuate and strongly divergent at apical 1 / 2, sinuate before apex; lateral margins evenly arcuate with four, small, sharp teeth near apex. Penis very broad, less well-sclerotized than parameres, medially inflated at basal 2 / 3 between parameres forming a longitudinal, margined, flat-topped carina; apex bell-shaped, tip produced and bent ventrally; no visible corona; basal apophyses moderately long, 1 / 2 - 2 / 3 as long as phallobase, straight, very broad, transversely truncate at tips. In lateral view (Fig. 42 B), aedeagus widest midway between apex and base; paramere broadly triangular in outline, moderately convex dorsally, moderately concave ventrally, apex acute; penis apex narrowly rounded, curved ventrally slightly above paramere apex. In ventral view (Fig. 42 C), parameres with arcuate median margins, thickened at basal 1 / 3; penis with tip longitudinally carinate, fibula absent. Ovipositor: Well-sclerotized; elongate, 2.5 x longer than wide; baculum 1 / 4 longer than gonocoxite; proximal gonocoxite subrectangular except widened medially at base, with two teeth; distal gonocoxite 2 x longer than proximal gonocoxite, base 2 x wider than apex, apex broader than middle, median margins straight, lateral margins sinuate; stylus narrow, 1 / 4 - 1 / 3 length of distal gonocoxite.	en	Barr, Cheryl B., Shepard, William D.
