Subtribe Exocarpocorina

REVISED DIAGNOSIS: Female with enlarged sclerotized plates in vestibulum; endosoma in male either long, forming partial to complete coil, and with secondary gonopore subapical, or relatively short, J-shaped, secondary gonopore submedial, and with spine arising at level of sec- ondary gonopore and sometimes one or more additional medial or apical spines; left paramere sometimes uniquely and bizarrely modified.

DISCUSSION: Our assignment of taxa to the Exocarpocorina may benefit from a brief discussion of the history of recognition of the group and the rather casual interpretation of their interrelationships to date. Polyozus Eyles and Schuh (2003) , with six new species from New Zealand, was assigned to the Phylini by its authors. Weirauch (2007) extended the distribution of the taxon to Australia, and included two additional genera ( Ancoraphylus Weirauch , Exocarpocoris Weirauch ) in her “ Polyozus group,” for which she recognized the unique nature of the endosoma in the male and the posterior wall in the female. In her phylogenetic analysis of relationship among Polyozus -group species, Weirauch (2007) included Xiphoides sp. (also described by Eyles and Schuh, 2003 , with 6 spp. from New Zealand) as one of the outgroup taxa. Schuh et al. (2014) treated Polyozus as a junior synonym of Leptidolon Reuter, 1904 , originally described with one species from SE Australia. Genera now placed in the Exocarpocorina , including the four described in the present paper, are:

Ampimpacoris Weirauch and Schuh, 2011 , 1

Jiwarli Soto and Weirauch, 2009 , 4 spp. from Australia

Leptidolon Reuter, 1904 , 1 sp. from Australia and 6 spp. from New Zealand Leptospermia Schwartz, Weirauch, and Schuh , new genus, 2 spp. from Australia Mecenopa Eyles and Schuh, 2003 , 1 sp. from New Zealand

Melaleucacoris Schwartz, Weirauch, Schuh , new genus, 1 sp. from Australia Melaleucoides Schuh and Weirauch, 2010 , 18 spp. from Australia

Pimeleocoris Eyles and Schuh, 2003 , 3 spp. from New Zealand

Protemiris Russell and Weirauch, 2017, 5 spp. from Australia

Scholtzicoris Schuh, 2016 , 1 sp. from Australia Teddus Schwartz, Weirauch, and Schuh , new genus, 1 sp. from Australia Tryptomenomiris Schuh and Weirauch, 2010, 2 spp. from Australia

Wallabicoris Schuh and Pedraza, 2010 , 37 spp. from Australia

Xiphoidellus Weirauch and Schuh, 2011 , 6 spp. from Australia

Xiphoides Eyles and Schuh, 2003 , 6 spp. from New Zealand

Cladograms of relationships of some of these taxa, and their contained species, are included in the works of Weirauch (2007), Schuh and Pedraza (2010), Schuh and Weirauch (2010), Weirauch and Schuh (2011) , and Russell and Weirauch (2017). Unfortunately, none of these analyses come close to including representatives of all the genera now included in this presumed Gondwanean subtribe by Menard et al. (2013) and Schuh and Menard (2013). In addition, the choice of outgroup taxa has not been consistent, in part because most of the analyses were prepared prior to the larger analysis of Menard et al. (2013) on which current tribal-level assignments are heavily based or before the currently understood range of taxonomic and morphological diversity was recognized.

Our placement of four new genera in the Exocarpocorina includes decisions based heavily on male and female genitalic morphology. Description of these new taxa extends the range of known morphological, geographic, and host diversity in the Exocarpocorina . We do not attempt, however, to prepare a classification that recognizes monophyletic generic groupings within the Exocarpocorina . Nonetheless, having participated in extensive fieldwork in Australia and South America, as well as having examined nearly all relevant available collections of Phylinae from these continental areas, we are confident that the point has been reached where a detailed analysis of relationships within the Exocarpocorina should be undertaken.
