Variation (females). Some specimens have entire scapus yellow to light brown, some have scapus yellow laterally; basal part of metafemur of some specimens are yellow to very light yellow. Of the examined 90 females, about 10 specimens vary in number of teeth on hind femora, i.e. some of them are missing the second (the smallest) teeth on right metafemur, some of them are missing the second teeth on left metafemur.

MALE (N = 35): Length of body 2.7–3.26 mm. Similar to females except as follows: head 1.14–1.3x as broad as high; frontovertex 0.78–1.04x as broad as eye height; eye 1.20–1.44x as high as long; parascrobal protuberance 0.16–0.22x as high as head height; malar space 0.48–0.73x as long as breadth of oral fossa and 0.32–0.39x as long as eye height; flagellum longer, 1.43–1.63x as long as breadth of head, pedicel 0.93–1.48x and F7 1.20–1.61x as long as broad; POL 2.24–3.21x OOL, OOL 0.50–0.71x POD; metasoma with yellow subbasal ring extend to 4/5 of metasoma; parascrobal protuberance more raised than in females, about 0.2x as long as eye length (only about 0.13x in females).

Variation (males). There have been reported so called homeomorph and heteromorph (or even their intermediates) males to be found within various genera of Podagrionini   (for more details see Delvare 2005). We have found homeomorph and heteromorph males, including some intermediates, within our samples.Most of the examined males have been reared from the same egg case of Archeomantis sp. (lc_11–14, lc_50–52, and lc_130–146, respectively). Homeomorph males are similar to females with slightly different sculpture on propodeum ( Figure 1i View Figure 1 ). The intermediates and true heteromorph ( Figure 10a View Figure 10 ) males differ in having slightly enlarged all tibiae and mesobasitarus ( Figure 9d View Figure 9 ), in number of teeth on metafemur and shape of metatibia ( Figure 9 View Figure 9 e–f), in sculpture of propodeum, and shape of petiolus ( Figure 9g, h, j, k View Figure 9 ). Within all examined males 5 specimens were true homeomorphs, 20 specimens true heteromorphs, and 10 intermediates.

Distribution. Australia (Queensland, Australian Capital Territory, New South Wales, South Australia, Victoria) and New Caledonia.

Biology. All specimens with known host associations were reared from egg cases of Archimantis   sp.

Taxonomic remarks. The comparison of the material preliminarily named morphospecies 1 group A with the type material of the Australian members of the genus Podagrion   revealed that morphospecies 1 group A corresponds to P. koebelei Crawford, 1912   and its synonyms P. dolichurum Cockerell, 1930   and P. grotii Girault, 1915   . The remnant of holotype (for holotype condition see below) as well as the non–type material show all generic characters of Lasallegrion   . Accordingly, the above redescribed species is transferred into Lasallegrion   .

The holotype of L. koebelei   lacks head and antennae, the left fore wing is partially covered with glue, the right fore wing and the right hind wing are missing. Unfortunately, the holotype of L. koebelei   was damaged during examination for this study, when the plastic card it was mounted on broke at the point where the pin went through. Right hind leg, part of the left hind leg, left fore wing and metasoma were detached from the rest of the body and were mounted on a separate card. The P. grotii   type is completely fragmented. It consists of one card–mounted metacoxa, a severely damaged head, antennal parts and a metatibia mounted on a broken slide. It cannot be stated with certainty that all of these fragments actually belong to the same specimen. The type of P. dolichurum   is complete and intact. Thus, a complete set of diagnostic characters can only be obtained by combining the types of P. koebelei   and P. grotii   with the type specimen of P. dolichurum   .

Additionally, we identified two new synonyms of L. koebelei   , P. holbeini   , and P. metatarsum   ( Figure 10 View Figure 10 b–c).

The three syntypes of P. holbeini   (two females and one male mounted on one single card) partially lack heads, but the rest of the body allows us to reliably assign all three specimens to the same species that matches our concept of L. koebelei   . The synonymy of P. holbeini   with L. koebelei   had been suggested already by Bouček (1988).

The five syntypes of P. metatarsum   (three females and two males mounted on one single card (SAMA); plus two slides – one (SAMA) with two antennae mounted separately on a slide, labelled ‘ Podagrion metatarsus Gir.   , Type ♀ ’; second (QMB) with fragmented head and antennae on it, labelled ‘ Podagrion metatarsus Gir.   , Type ♀ ’, 5097) are also partially damaged or fragmented, yet there are enough characters visible that allow assignment to the same species which matches our concept of L. koebelei   . Similar to P. holbeini   , the synonymy of P. metatarsum   with L. koebelei   had been suggested already by Bouček (1988).

Although L. koebelei   is fairly similar to L. virescens   , it can be easily distinguished from the third species of the genus, L. washingtoni   , by its very long ovipositor, the funicular segments being always longer than broad, and by the number and shape of the metafemoral teeth. In L. washingtoni   the ovipositor is distinctly shorter, the antennal funicle is stouter with its distal segments being quadrate to subquadrate, and the metafemur bears more and smaller ventral teeth than the metafemur of L. koebelei   (and L. virescens   ). A molecular delimitation of L. koebelei   plus L. virescens   and L. washingtoni   was not possible, because for L. washingtoni   no COI sequence data could be obtained.

Lasallegrion koebelei   and L. virescens   can be differentiated either based on genetic divergence of COI sequences (94.08–94.83%) or morphologically, even if some specimens of both species overlap in some characters, and a combination of all characters is needed to reliably distinguish both species. Furthermore, the multivariate ratio analysis (MRA) resulted in a useful separation of L. koebelei   from L. virescens   and gave further evidence to separate taxa.
