Resolving the identities of Phylinae (Heteroptera: Miridae) described by O.M. Reuter from Australia in 1904.

Abstract--Examination of photographs and specimens from the Museum Victoria, Melbourne, Australia, allows for the incorporation of three taxa described by Reuter from Australia in 1904 into the modern classification of Miridae: Phylinae. Leptidolon vittipenne Reuter is judged to be congeneric with Polyzus galbanus Eyles and Schuh; because Leptidolon Reuter is the older name. Polyozus Eyles and Schuh is treated as a junior synonym of Leptidolon, new synonym. Psallus eximius Reuter is transferred to Wallabicoris Schuh and Pedraza, new combination, and is treated as the senior synonym of Wallabicoris cuneotinctus Schuh and Pedraza, new synonym. Sthenarus australis Reuter is transferred to Ausejanus Menard and Schuh, new combination.

Reuter (1904) described three species of Phylinae from Australia as part of his larger effort to describe and produce a classification for the world Miridae: Leptidolon vittipenne Reuter, Psallus eximius Reuter, and Sthenarus australis Reuter. With the exception of catalog entries (Carvalho, 1958; Schuh. 1995, 2002-2013), no further mention of these taxa exists in the literature. Although Reuter listed the single specimen for each species as being from Victoria (without exact localities), there was no indication in the original publication of where the specimens were deposited. With the advent of on-line collection databases, it has now come to our attention that the holotypes of all three species are deposited in the Museum Victoria, Melbourne.

Leptidolon Reuter

Leptidolon Reuter, 1904: 14 (n. gen.)

Polyozus Eyles and Schuh, 2003: 303 (n. gen.); Weirauch, 2007: 39 (descr., disc.). New Synonym

Dissection of the holotype of Leptidolon vittipenne Reuter, the type species of this genus reveals that it is a member of the nominal genus Polyozus Eyles and Schuh, 2003. This means that Polyozus is a junior synonym of Leptidolon. Leptidolon vittipenne is distinct from the species described by Carvalho (1965), Eyles and Schuh (2003), and Weirauch (2007) based on features of the male genitalia. All species previously placed in Polyozus must therefore be transferred to Leptidolon with the creation of the following new combinations: Leptidolon australianus (Carvalho, 1965), L hulita (Weirauch, 2007), L. furcilla (Weirauch, 2007), L galbanus (Eyles and Schuh, 2003), L. kojonup (Weirauch, 2007), L. kuringgai (Weirauch, 2007), L. manila (Weirauch, 2007), L. mina (Weirauch, 2007), and L. Widens (Weirauch, 2007).

Leptidolon vittipenne Reuter

Fig. 1

Leptidolon vittipenne Reuter, 1904: 15 (n. sp.).

We have illustrated the male genitalia of L. vittipenne in figure 1. The structure of the endosoma indicates that this taxon is distinct and likely most closely related to L. furcilla (Weirauch, 2007) and L. Widens (Weirauch, 2007), based on the form of the median apical process of the endosoma. This process is dendriform in most species of Leptidolon', L. furcilla and L. Widens feature a heavily sclerotized process that is apically bifurcating, and L. vittipenne has a relatively short process with a bluntly bifurcating apex. Because the endosoma was broken during dissection, our drawing shows a fracture line just distad of the secondary gonopore. This specimen is missing the possess arising near the secondary gonopore (see characters 19 and 28 in Weirauch, 2007) that is diagnostic for all other species of Leptidolon. This process is rather fragile, and easily detaches at its base during dissection. We argue that the lack of this process is likely a dissection artifact and predict that dissection of additional specimens, should they become available in the future, will confirm the presence of a short, straight process. The anterior process of the left paramere is heavily sclerotized, an attribute that we have emphasized in figure 1. A photograph of the holotype is available through the Museum of Victoria website (http://collections. =1018462).

Wallabicoris eximius (Reuter), new combination Psallus eximius Reuter, 1904: 12 (n. sp.).

Wallabicoris cuneotinctus Schuh and Pedraza, 2010: 30 (n. sp.). New Synonym

Comparison of photographs of the holotype of Psallus eximius Reuter on the web site of the Museum Victoria ( object.php?im= 1018466) with those provided by Schuh and Pedraza (2010) indicate that this nominal species is the senior synonym of Wallabicoris cuneotinctus Schuh and Pedraza. Therefore the correct name for this taxon is Wallabicoris eximius (Reuter).

Ausejanus australis (Reuter), new combination

Sthenarus australis Reuter, 1904: 13 (n. sp.).

Examination of photographs of the female holotype of Sthenarus australis Reuter (1904) ( php?irn= 1018467) indicates that this nominal taxon almost certainly represents a species of Ausejanus Menard and Schuh (2011). This specimen was not recognized by Menard and Schuh (2011) as a member of the Leucophoropterini and was therefore not included in their treatment of the tribe. The unique reddish coloration of the head, thorax and abdomen in combination with the yellow coloration of the femora and patterning of the transverse fascia on the hemelytron indicate that this specimen represents a separate species from other described taxa of Ausejanus. Ausejanus albisignatus (Knight) has the head, thorax, pronotum and abdomen black to at most dark brownish-red, as do other members of Ausejanus, including those with yellow femora, with the exception of A. neboissi (Carvalho and Gross) and A. macrozonata (Carvalho and Gross). We rule out A australis as being a synonym of A. neboissi because of the shape of the transverse fascia (defined and white, unlike the broad and yellow fascia of A. neboissi) and of A. macrozonata because of the shape of the fascia and the femora in australis are yellow, not dark red as in A. macrozonata.
