Thorax ( Fig. 85b View FIGURE 85 ): Pronotum longer than wide; posterior margin slightly wider than anterior; subapical furrow present; mostly pale with a central longitudinal black “Y” shaped line, and two longitudinal thin bands surrounding the central one (some darker specimens with black areas larger and fused); set with many short and long black setae, but with few long white setae at anterior margin. Mesonotum with prescutum and scutellum pale with a central black longitudinal band, scutum pale with black longitudinal bands (some darker specimens mostly black with small pale spots); covered with short black setae, and some elongate black setae, mainly on prescutum anteriorly. Metanotum with three longitudinal black bands, a central and two marginal, intercalated with pale bands; covered with short black setae. Pterothoracic pleura dorsal segments mostly black with scattered pale spots but ventral segments mostly pale with some black marks, mainly on dorsal margins (some darker specimens with black areas larger); covered with elongate white setae. Miller’s organ present.

Wings ( Fig. 85c View FIGURE 85 ): Fairly broad with tip acute; anterior Banksian line present in both wings, posterior absent; veins set with short black setae, in general brown, except by the main longitudinal veins that are intercalated by numerous short white regions. Male pilula axillaris present. Forewing membrane almost hyaline with small brown marks as follows: on posterior margin, tip, pterostigma, subcostal area, around mediocubital crossveins, one small brown line on prefork area apex, and another on rhegmal area; CuA fork located between RP origin and first fork; three or four presectoral crossveins (specimens with four the distal one bifurcates); costal area large; with many subcostal veinlets forked; posterior area narrower than prefork area. Hind wing membrane hyaline except for a small brown mark on rhegmal area; MP fork located between RP origin and first fork; subcostal veinlets simple but few distal ones forked in some specimens; one presectoral crossvein.

Legs ( Figs. 85 View FIGURE 85 a–b): All pairs of legs, femur elongate (> 3.5x length of coxa); tibia about same size of femur but longer than tarsi; tibial spurs surpassing T2 tip; T2, T3 and T4 about same size, T1 about twice as long as T2, T5 about twice as long as T1; claws about half of T5 length; coxa, trochanter, and femur set with short white setae; femur, tibia and tarsi set with short black setae, and scattered long black setae; T5 ventrally with two rows of thick, long, black setae. Proleg femur sense hair absent; tibia with antennal cleaning setae ventroapically; coxa mostly pale with irregular black marks; trochanter pale; femur pale with tip dark brown; tibia mostly pale with three dark brown rings; tarsi with T3, T4 and tip of T5 dark brown, remaining areas pale. Mesoleg with same colour pattern of proleg. Metaleg with femur, tibia and T1 slightly longer than in other legs; colouration similar to other legs, except for tibia pale, with tip dark brown.

Abdomen: In general, mostly black with many irregular pale marks, but in some specimens the pale marks are dominant. Beset with short black setae.

Male Terminalia ( Figs. 86 View FIGURE 86 a–d): Ectoproct posterior margin rounded in lateral view, set with elongate black setae. 9 th sternite in ventral view, with large medial invagination; covered with elongate black setae. Gonarcus arched with lateral areas broad in posterior view; curved in lateral view. Mediuncus short and forked at tip. Paramere broad with an acute medial extension in lateral view.

Female Terminalia ( Figs. 86 View FIGURE 86 e–f): Ectoproct posterior margin rounded and covered with thin elongate setae. Lateral gonapophyses rounded, smaller than ectoproct, set with cavisetae. 7 th sternite distal margin straight in ventral view; covered with long black setae. Pregenital plate elongate longitudinally, with posterior margin rounded in ventral view. Posterior gonapophyses broad, elongate, with tip slightly enlarged; covered with long black setae, and cavisetae on apex. 9 th tergite with an elongate membranous digitiform process. Anterior gonapophyses as two small rounded lobes, set with few thickened setae. Ventral membrane, gonapophyseal plates present.

Distribution ( Fig. 87 View FIGURE 87 ). Australia: NSW, NT, QLD, SA, VIC, WA. Widespread and common across mainland

Australia.

Adult activity period. Records for all months of the year; most records for October to February.

Biology. Unknown, larva unknown.

Name-bearing types. Myrmeleon osmyloides   : Holotype (by implicit monotypy), male [not female], ZIMG, high-resolution images examined. Type locality: Australia. From original description: “(Fem.).—Patria: Australia ”. From New (1985b): “Types / Holotype of Myrmeleon osmyloides   'Australia' (Greifswald, not seen)”. From New (1996): “Type data: holotype EMAG adult sex indet.*. / Type locality: Australia ”.

Gerstaecker’s (1885a) statement that the apparently single specimen upon which the species was based is a female is incorrect; the presence of a pilula axillaris at the base of the hind wing demonstrates that the holotype is a male. Condition: good, missing left hind wing and hind leg.

Glenoleon annulicornis   : Holotype (by original designation), female, BMNH, high resolution images examined. Type locality: Australia. From original description: “ Victoria; one specimen (Coll. Esben-Petersen), the other not labeled. Type in Coll. West Australian Museum, Perth; cotype in Coll. Esben-Petersen”. From New (1985b): “ G. annulicorne   was described from two specimens: the type, designated as having no data, stated to be in WAM. I did not find any such specimen in WAM. There is in BMNH, though, a specimen of this species, tallying exactly in leg positions with Esben-Petersen's photograph, and also lacking abdomen (also now antennae): labelled as Type (seen). I believe this to be the type”. From ( New 1996): “Type data: syntypes BMNH 1 adult sex indet. (whereabouts of other syntypes unknown)”.

The statements made by New (1985b) are confirmed here; the holotype stated by Esben-Petersen (as “Type”)

to be deposited in the WAM is now in the BMNH. The specimen is identical to the picture presented in the original description and also bears a type label. The sex of the holotype was never mentioned but it is clearly a female because of the absence of the pilula axillaris. The “cotype” (a paratype) with location unknown was located during this study. It is a male deposited in the ZMUC; labels: Vict. (small pale square), Glenoleon annulicorne   n. sp. Esben Petersen Cotype (large white rectangle), cotype (elongate red rectangle). Specimen in general well preserved: right meso leg missing, and tip of the wings damaged.

Glenoleon gerstaeckeri   : Holotype (by original designation), male, AMSA, high-resolution images examined. Type locality: Australia, Western Australia, Kalbarrie (town). From original description: “ Holotype, ♂, Western Australia, Kalbarrie, 22.xi.1978, M.S. and B.J. Moulds (AM)”. Condition: good; right metaleg missing; terminalia dissected.

Comments. Synonymy of Glenoleon annulicornis: The   synonymy of Glenoleon annulicornis   under G. osmyloides   , first proposed by Esben-Petersen (1923) and later corroborated by New (1985b), is confirmed here once again. The two specimens of the type series of G. annulicornis   were re-examined and it is clear that both belong to G. osmyloides   .

Synonymy of Glenoleon gerstaeckeri: In   the original description of G. gerstaeckeri   New (1985b) noted its resemblance to G. osmyloides   , but differentiated the species based on the abdominal pattern and genitalia. Re-examination of the holotype of G. gerstaeckeri   for this work has shown it to be very similar to G. osmyloides   -- its general body marks, leg lengths, and wing shape and venation are almost identical. The abdominal pattern mentioned by New is not a robust character and is one of the most variable characteristics of the Periclystus   genus group. The holotype is only slightly paler than typical G. osmyloides   specimens. The genitalia are essentially identical to G. osmyloides   , the only difference being the slightly wider parameres (a character too weak to sustain the species). Based on these observations Glenoleon gerstaeckeri   is here synonymized with Glenoleon osmyloides   .
