Phaloria Stål, 1877

Tan, Ming Kai, Rahmadi, Cahyo & Robillard, Tony, 2021, New species of Phaloria (Orthoptera: Phalangopsidae: Phaloriinae) from West Papua (Indonesia), Zootaxa 4985 (4), pp. 513-530 : 514-515

Genus Phaloria Stål, 1877

Diagnosis (based on Gorochov, 1996). This genus is characterised by inner and outer tympana open but relatively small; male ectophallic apodeme [rachis] isolated from endophallic sclerite [formula], rami separated from each other (instead of connected in the anterior parts), and pseudepiphallic paramere [ectoparamere]; apex of female ovipositor with 2–4 and 1–4 large rounded lateral teeth on the upper and lower valves, respectively.

Remarks. This speciose genus is split into four subgenera, and now comprises 68 described species. The genus is distributed from the islands of western Indian Ocean, across the Southeast Asian mainland and archipelago, Australia to the western Pacific islands.

The subgenera are differentiated exclusively by characters in the male genitalia. The subgenus Papuloria Gorochov, 1996 is more speciose, consisting of 42 species, of which 22 are recorded from New Guinea. The nominal subgenus Phaloria consists of 17 species, of which one is recorded from New Guinea. The subgenera Sulaweloria Gorochov, 2011 (from Sulawesi) and Trelloria Gorochov, 1996 (from New Guinea and Solomon Islands) consist of one and two species, respectively. Six species do not have an assigned subgenus. The monophyly of the subgenera will have to be demonstrated using phylogenetic analyses in future studies.

Here, we describe six new species from West Papua, New Guinea:

Phaloria dischidia Tan & Robillard , sp. nov. from Lobo

Phaloria paradischidia Tan & Robillard , sp. nov. from Kumawa

Phaloria tukul Tan & Robillard , sp. nov. from Lobo

Phaloria brevis Tan & Robillard , sp. nov. from Kumawa

Phaloria berbeda Tan & Robillard , sp. nov. from Lobo

Phaloria lobulata Tan & Robillard , sp. nov. from Kumawa

Key to subgenera of Phaloria

1. Pseudepiphallus with a pair of lateral lophi................................................................. 2

-. Pseudepiphallus with two pairs of lophi: one pair of longer lateral lophi and another pair of shorter medial lophi.......... 3

2. Endophallic sclerite with large unpaired apodeme directed anteriorly.............................. subgenus Trelloria

-. Endophallic sclerite without large unpaired apodeme directed anteriorly........................... subgenus Papuloria

3. Pseudepiphallus with median part “ribbon-like”. Endophallic sclerite strongly reduced. Distribution: only Sulawesi .......................................................................................... subgenus Sulaweloria

-. Pseudepiphallus without median part “ribbon-like”. Endophallic sclerite not strongly reduced. Distribution: not Sulawesi (Malay Peninsula, Taiwan, Philippines, Maluka, New Guinea, Solomon Islands, western Pacific islands, Australia)................................................................................................. subgenus Phaloria
