Mount Haig, state of Queensland, northeastern Australia (17°06’S, 145°29’E).

Scolytocis australimontensis sp. n. can be distinguished from other Australian and Oriental species of Scolytocis by the combination of the following features: pronotum with a conspicuous rugose border along the posterior edge and smooth interspaces of punctures; metatibiae with a clear distinction between the outer and apical edges, the outer edge being straight and bearing at least five spines separated from each other by more than a spine-width. Scolytocis novazelandiae has a similar posterior pronotal border, but interspaces of punctures are microreticulate. Scolytocis werneri has a comparatively narrower posterior pronotal border and interspaces of punctures are coarsely reticulate.

The species name derives from the Latin adjectives “australis”, which means “of the South” and refers to Australia, and “montensis”, which means “of or belonging to mountains”, both in the genitive singular. The name is a reference to the Australian mountains where most specimens were collected.

This new species was collected only in localities above 800 m, three of them at Australian mountains (Mount Haig, Mount Edith and Mount Bartle Frere) (Fig. 24). This species may be included in the Sc. werneri species-group, in which the species have a rugose border along the posterior pronotal edge.

Federated States of Micronesia: holotype (ANIC) labeled “PONAPE ISLAND: Colonia, iii.1998, H. S. Dybas, FMHN [printed]\Scolytocis insularis Souza-Gonçalves & Lopes-Andrade HOLOTYPUS [printed on red paper]”. Paratype: one female (CELC, dissected), same locality data as holotype and additionally labeled\Scolytocis insularis Souza-Gonçalves & Lopes-Andrade PARATYPUS [printed on yellow paper].

The species name is a Latin adjective in the genitive singular and means relative or belonging to an island, in reference to the insular distribution of this species.

This new species is known only from the type locality, Kolonia, a coastal town and capital of the state of Pohnpei in the Federated States of Micronesia (Fig. 24). The species does not fit in any previously proposed species-group of Scolytocis. Here, we propose the Sc. insularis species-group to encompass this single species, the group defined by the combination of the following features: biconcave prosternum; outer edge of metatibiae slightly rounded, without a clear distinction between outer and apical edges. The prosternum is also biconcave in species of the Scolytocis danielssoni and the Scolytocis fritzplaumanni species-groups. However, in the Sc. danielssoni species-group the species are comparatively larger and have a rugose border along the posterior pronotal edge. In the Sc. fritzplaumanni group the species are also larger than Sc. insularis and bear a smooth border along the posterior pronotal edge. Metatibiae with slightly rounded outer edge are also seen in species of the Scolytocis bouchardi and the Scolytocis lawrencei species-group, but they have triconcave and tumid prosternum, respectively, and are exclusively neotropical.

Guam: 15 specimens (8 ANIC; 7 CELC, including 2 dissected females) labeled “MARIANAS: Guam, Ritidian Point, 29.v.1945, #2086 FMNH in polypore, H. S. Dybas”.

Scolytocis samoensis is the type species of the genus and was described based on a single specimen from Samoa, possibly a female, deposited in the Bernice Pauahi Bishop Museum (Hawaii, USA). Blair (1928) mentioned the poor condition of the holotype. This species was tentatively included in the Sc. lawrencei species-group by Lopes-Andrade (2008) and here we keep the same opinion. The specimens we examined from Guam (Fig. 24) fit the original description by Blair (1928).

The new species is named in honor of the ornithologist Dawn Whyatt Frith, who collected all specimens from the type locality. The species name is Latinized from “Frith” using the feminine suffix in the genitive singular (-ae).

This is the first described species of Xylographella from the Australian region. The genus encompasses only two other species: X. punctata Miyatake, 1985 and X. speciosa Lopes-Andrade, 2008, the former from the Japanese islands of Honshu and Shikoku, and the latter from the provinces of Mindanao and Luzon in the Philippines. Images of X. frithae were recently provided by Lawrence (2016).
