Diagnosis. Atyphella species have aedeagal LL visible at the sides of the ML and an aedeagal sheath with posterior area of sternite emarginate on its right side from attachment of the right arm of the tergite. Most species are from Australia, the island of New Guinea and the Solomon Islands. Males of Australian species, and Aty. rennellia and Aty. scabra , with anterior hypomeron flat to neck, and posterior area flattened and strongly adpressed; in non-Australian species the anterior hypomeron is not strongly adpressed; epipleuron either continuing around elytral apex as a ridge ( Ballantyne & Lambkin 2009 figs 9–11, 79, 83, 118, 119, 122–125, 127–129, 169, 170) or not; frons-vertex junction rounded, sometimes angulate ( Ballantyne & Lambkin 2009 figs 84, 85); mouthparts usually functional; apical segment of labial palpi either strongly flattened, with inner margin dentate, or ovoid with inner margin entire, without the asymmetrical T8 of Asymmetricata (that of Atyphella is not emarginated); differing primarily in colour pattern from Convexa and M. limbata , both of which have distinctive dark elytra with pale margins; without the dorsal colour pattern, shape of aedeagus and hooded basal piece of Lloydiella , and without the arched V7 with LO retracted to anterior half or less characteristic of Pygatyphella and Pacifica . Females ( Ballantyne & Lambkin 2000, fig 6; 2009 figs 130–136; 2013 Table 7 ) either macropterous or exhibiting varying degrees of brachelytry. Larvae with laterally explanate tergal margins concealing laterotergites from above ( Ballantyne & Lambkin 2000 figs 7, 12 a, b, 15a−c).

Remarks. The version of Atyphella addressed by Ballantyne & Lambkin (2000) was restricted to Australia and included 16 Australian species of which two, ( costata Lea and majuscula Lea ) have subsequently been transferred elsewhere ( Aquilonia and Lloydiella respectively). Species were keyed from males, females from 11 species (including costata Lea and majuscula Lea ) and larvae from 7 species (including majuscula Lea ).

Ballantyne & Lambkin (2009: 34) reassessed the genus from a wider perspective including New Guinea and Pacific islands, addressed 23 species of which three were new, and transferred both Aty. costata and Aty. majuscula to Aquilonia and Lloydiella respectively. Species were primarily distributed along the eastern coast of Australia to Kiama in New South Wales, and in the island of New Guinea.

Atyphella is now represented by 28 species which extend its range both to the east, north and west of the island of New Guinea. Females are associated for nine species and larvae for seven. Ballantyne et al. (2015: fig. 1B) presented an Atyphella ‘complex’ of 26 species which included two species of Magnalata , rennellia and carolinae , and Luciola striata . These three species are assigned here to Atyphella , in addition to Luciola abdominalis Olivier. Atyphella rennellia comb. nov. and Aty. carolinae comb. nov. occur to the east of the island of New Guinea in the Solomons, and to the north in the Republic of Palau respectively. Two species were recorded from further west of New Guinea: the type specimen of Aty. testaceolineata Pic from the Maluku Islands, and a possible record of Aty. guerini Ballantyne from Halmahera ( Ballantyne & Lambkin 2009: 45, 53). Two additional species assigned here extend that westerly range further viz. Aty. striata (F.) comb. nov. from Java and Aty. abdominalis (Olivier) comb. nov. from the Philippines making this the only Philippines record and the most westerly distribution of this genus.
