Six new species of the genus Exocelina Broun, 1886 from Wano Land, New Guinea (Coleoptera, Dytiscidae, Copelatinae).

ABSTRACT: Six new species of New Guinea Exocelina Broun, 1886 are described in this paper: E. iratoisp. n., E. likuisp. n., E. puisp. n., E. pulukensissp. n., E. tomhansisp. n., and E. wigodukensissp. n. Although different morphologically, together with Exocelina ascendens (Balke, 1998), E. bagus (Balke & Hendrich, 2001), and E. ransikiensis Shaverdo, Panjaitan & Balke, 2016, they are found to form a monophyletic clade and be closely related to representatives of the E. ekari-group, based on preliminary analysis of sequence data. An identification key to the species is provided, and important diagnostic characters are illustrated. The present data on the species' distribution show that most of them are local endemics.

Exocelina baliem sp. n., the only known pond species of New Guinea Exocelina Broun, 1886 (Coleoptera, Dytiscidae, Copelatinae).

Project description:Exocelina baliem sp. n. is described from the Baliem Valley in the Central Mountain Range of New Guinea (Papua Province, Indonesia). Having striolate elytra, different structure and setation of the male and female genitalia and tarsomeres, and inhabiting swampy ponds, the new species differs from all known New Guinea species, which have smooth elytra and are stream associated. It forms a monophyletic group with the Australian Exocelina ferruginea (Sharp, 1882) and New Caledonian Exocelina inexspectata Wewalka, Balke & Hendrich, 2010, based on shape of the paramere and structure of the male tarsi. Habitus, protarsomeres, and male and female genitalia are illustrated, comparing some structures with Exocelina ferruginea and two New Guinea stream species. We briefly discuss the biogeographic relevance of this discovery.

Nine new species groups, 15 new species, and one new subspecies of New Guinea diving beetles of the genus Exocelina Broun, 1886 (Coleoptera, Dytiscidae, Copelatinae).

Project description:Nine new species groups of Exocelina Broun, 1886 from New Guinea are introduced with keys to their representatives. Four groups are monotypic and include three new species: the E. aipomek group, the E. koroba group: E. koroba sp. nov., the E. mekilensis group: E. mekilensis sp. nov., and the E. morobensis group: E. morobensis sp. nov. The remaining five species groups include 18 species with 12 new species and one new subspecies: the E. bacchusi group: E. akameku sp. nov., E. oiwa sp. nov., E. oksibilensis sp. nov., and E. bacchusi herzogensis ssp. nov.; the E. jaseminae group: E. aseki sp. nov., E. kailaki sp. nov., and E. pseudojaseminae sp. nov.; the E. larsoni group: E. warahulenensis sp. nov.; the E. takime group: E. mianminensis sp. nov.; and the E. warasera group: E. haia sp. nov., E. kobau sp. nov., E. pulchella sp. nov., and E. warasera sp. nov. Diagnoses of five already described species of these groups are provided, as well as comparatives notes on all species. Exocelina santimontis (Balke, 1998) syn. nov. is a junior synonym of E. aipomek (Balke, 1998). Data on the distribution of the species are given, showing that most of the species of these groups occur in the Papua New Guinea.

Three new species of Exocelina Broun, 1886 from the southern slopes of the New Guinea central range, with introduction of the Exocelina skalei group (Coleoptera, Dytiscidae, Copelatinae).

Project description:Three new species of the genus Exocelina Broun, 1886: E. brazza sp. nov., E. amabilis sp. nov. and E. mimika sp. nov. are described from New Guinea. The former two species are placed into the E. ekari group, while the latter is suggested to be a member of a separate lineage, the newly introduced E. skalei group. The only other species of that group is E. skalei Shaverdo & Balke, 2014. The group is phylogenetically sister of the E. ekari group. All species have been collected on the southern slopes of the New Guinea central range, a region that remains mostly unsampled.

Introduction of the Exocelina ekari-group with descriptions of 22 new species from New Guinea (Coleoptera, Dytiscidae, Copelatinae).

Project description:The Exocelina ekari-group is here introduced and defined mainly on the basis of a discontinuous outline of the median lobe of the aedeagus. The group is known only from New Guinea (Indonesia and Papua New Guinea). It contained four species to date: Exocelina astrophallus (Balke, 1998), Exocelina atowaso (Shaverdo, Sagata & Balke, 2005), Exocelina munaso (Shaverdo, Sagata & Balke, 2005), and Exocelina polita (Sharp, 1882). Twenty two new species are described herein: Exocelina alexanderisp. n., Exocelina anggiensissp. n., Exocelina arfakensissp. n., Exocelina bifidasp. n., Exocelina brahminensissp. n., Exocelina bundiensissp. n., Exocelina edeltraudaesp. n., Exocelina ekarisp. n., Exocelina emesp. n., Exocelina evelyncheesmanaesp. n., Exocelina hansferyisp. n., Exocelina irianensissp. n., Exocelina kakapupusp. n., Exocelina knoepfchensp. n., Exocelina oceaisp. n., Exocelina pseudosoppisp. n., Exocelina soppisp. n., Exocelina uniposp. n., Exocelina utowaensissp. n., Exocelina waigeoensissp. n., Exocelina weylandensissp. n., and Exocelina wondiwoiensissp. n. The lectotype of Copelatus politus Sharp, 1882 is designated. A checklist and identification key to all species of the group are provided and important diagnostic characters (habitus, color, male antennae and protarsomeres 4-5, median lobes and parameres) are illustrated. Data on the distribution and habitat requirements are given. Representatives of the Exocelina ekari-group are so far mostly known from lowland to lower montane habitats of the northern and central parts of New Guinea, the group is less diverse in higher altitudes.

Seven new species of the Exocelina ekari group from New Guinea central and coastal mountains (Coleoptera, Dytiscidae, Copelatinae).

Project description:Seven new species of the genus Exocelina Broun, 1886 are described from three different mountain ranges of New Guinea: E. foja sp. nov., E. riberai sp. nov., E. apistefti sp. nov., and E. waaf sp. nov. from the Foja Mountains; E. hudsoni sp. nov. from the Cyclops Mountains; E. ekpliktiki sp. nov. and E. oraia sp. nov. from Wano Land. All of them are placed into the E. ekari group based on the structure of their male genitalia. The species are characteristic dytiscid elements of the fauna of northern cost and the western part of central orogen of New Guinea. Two taxonomic notes are presented: Exocelina athesphati is a correct name for the recently described Exocelina athesphatos Shaverdo et al., 2020; Exocelina bacchus Balke, nom. nov. is a replacement name for Exocelina bacchusi (Balke, 1998), formerly Copelatus (Papuadytes) bacchusi Balke, 1998, a junior homonym of Copelatus bacchusi Wewalka, 1981.

Two new species of the Exocelina ekari group from New Guinea with strongly modified male antennae (Coleoptera, Dytiscidae, Copelatinae).

Project description:Two new species of the genus Exocelina Broun, 1886: E. athesphatos sp. nov. and E. tsinga sp. nov. are described from New Guinea and placed into the E. ekari group based on the structure of their male genitalia. The two species are very similar with respect to their external morphology and characterised by almost identical, strongly modified male antennae. However, they can easily be separated by the shape and setation of the median lobe and paramere. Based on morphological similarity and results of a molecular phylogenetic analysis, we suggest these are sister species. Both of them have been collected on the southern slopes of the Central Range (the spine of New Guinea), with a distance of ca. 380 km straight line between the collecting localities.

Taxonomic revision of New Guinea diving beetles of the Exocelina danae group, with the description of ten new species (Coleoptera, Dytiscidae, Copelatinae).

Project description:Ten new species of Exocelina Broun, 1886 from New Guinea are described: Exocelina andakombensissp. n., Exocelina garainasp. n., Exocelina injiensissp. n., Exocelina kabwumensissp. n., Exocelina marawagasp. n., Exocelina posmanisp. n., Exocelina tekadusp. n., Exocelina variratasp. n., Exocelina wareagasp. n., and Exocelina woitapensissp. n. All of them together with five already described species are united into the newly defined Exocelina danae-group (with Exocelina miriae-subgroup), a polyphyletic complex of related species with lateral setation on the median lobe. In the light of newly available material, all previously described species of the Exocelina rivulus-group are considered to belong to a single species, Exocelina damantiensis (Balke, 1998), which is now placed into the Exocelina danae-group, and three new synonyms are therefore proposed: Exocelina madangensis (Balke, 2001) syn. n., Exocelina patepensis (Balke, 1998) syn. n., and Exocelina rivulus (Balke, 1998) syn. n. Exocelina tarmluensis (Balke, 1998) syn. n. is a junior synonym of Exocelina danae (Balke, 1998). Redescription of Exocelina atratus (Balfour-Browne, 1939) is provided based on its type material. An identification key to all known species of the group is provided, and important diagnostic characters are illustrated. Data on the species distribution are given, showing that whilst most species are local endemics, Exocelina damantiensis is extremely widely distributed.

Description of two new species of the Exocelina broschii-group from Papua New Guinea, with revision and key to all representatives of this species group (Coleoptera, Dytiscidae, Copelatinae).

Project description:Two new species of Exocelina Broun, 1886 from Papua New Guinea are described herein: Exocelina mondmillensis sp. n. and Exocelina pseudomarinae sp. n. They are placed into the Exocelina broschii-group based on the shovel/fork-like ventral sclerites of their median lobe. While the former has rather distinct combination of the morphological characters (inconspicuous dorsal punctation, thin apex of the median lobe and ventral sclerite of the median lobe with two tips of different length), the latter is very similar to already described species Exocelina marinae (Shaverdo, Sagata & Balke, 2005). All described species of the group are revised and a key to their identification is provided. Important diagnostic characters (habitus, color, protarsomeres 4-5, median lobes, and parameres) are illustrated. Data on the distribution of all species of the group are given showing that its representatives occur only in Papua New Guinea and most of them are widely distributed in it central part.

Descriptions of two new species and one new subspecies from the Exocelina okbapensis-group, and notes on the E. aipo-group (Coleoptera, Dytiscidae, Copelatinae).

Project description:Two new species and one new subspecies of Exocelina Broun, 1886 from New Guinea are described: E. okbapensis Shaverdo & Balke, sp. n., E. okbapensis hajeki Shaverdo & Balke, ssp. n., and E. may Shaverdo & Balke, sp. n. These and two already described species are assigned to the E. okbapensis-group, which is morphologically (based on setation of the paramere) and phylogenetically close to the E. aipo-group. On the latter, morphological and taxonomic notes are provided. An identification key to all known species of the groups is presented, and important diagnostic characters are illustrated. Data on the species distributions are mapped and show that the species occur only in the central mountain part of the island restricted by Wamena in the west and Sandaun Province in the east.
