A taxonomic synopsis of the orchid genus Habenaria in New Guinea and adjacent islands is presented. We confirmed the occurrence of 27 Habenaria species in study area. Sixteen of these are endemic and were not so far found outside New Guinea. Morphological characteristics and illustrations of floral segments of taxa are presented. One new species of Habenaria is described. Four neotypes are selected. An updated key to species groups and species occurring in the study area is provided. The importance of diagnostic floral characters in Habenaria is discussed.

The Neotropical orchid genusPonthievaR. Br. was established in 1813. The 70 representatives of this taxon are terrestrial, lithophytic, or epiphytic plants with basal, sessile, or petiolate leaves which are glabrous or pubescent. Their erect peduncle is pubescent and terminated by lax, few- to many-flowered raceme. Flowers are non-resupinate, with dissimilar sepals and asymmetrical petals which are adnate to the sides of the gynostemium. The lip is uppermost, fused to the lower part of the gynostemium. Here the synopsis of ColombianPonthievais presented. A list of national genus representatives includes 26 species, including one new species,P. vallecaucanaSzlach. Kolan. & Olędrzyńska, sp. nov., discovered during this study. We did not confirm occurrence of four species reported in previous research. To facilitate process of identification of genus representatives, we dividedPonthievainto six morphological complexes based on vegetative and floral characters. The highest number of species was found in Magdalena and Cauca Valley montane forests. Lectotypes forPonthieva inauditaandP. mandoniiare designated. Morphological characteristics and illustrations of perianth segments of Colombian representatives of the genus are provided as well as a key for their identification.

The genus Tricimba. in its broadest sense. is revised from Australia. New Guinea. and Bismarck and Solomon Islands and Vanuatu . In all, 66 species are recorded from Australia. 39 from New Guinea and the Bismarck Archipelago. five from the Solomon Islands and two from Vanuatu . A total of 96 species is included in the keys: seven described species. 87 new species of Tricimba (T . aberrans.

Tricimba steatodae Hickman, 1971 is newly synonymised with T. convexa Malloch, 1927. The species considered are grouped into three genera and 17 species-groups within Tricimba. The relationships of the species-groups with each other and with extra-limital species-groups, and the relationships of the genera are tabulated and discussed. The genera Nartshukiella, Euhippelates, Eutricimba and Crassivenula are considered to correspond to the level of species-groups of Tricimba in this revision and are synonymised with Tricimba. The relationships of the tribes Tricimbini and Incertellini are discussed.

The genus Systenus Loew, 1857 is recorded from Afrotropical Region for the first time. A description of a new species, Systenus africanus Grichanov sp. nov., and notes on females of another probably new Afrotropical species are provided. The genus is considered now as cosmopolitan. A key to species and species groups of the Systenus worldwide is compiled.

Species within Gennadas differ from each other largely only in male (petasma) and female (thelycum) copulatory characters, which were restudied in scanning electron microscopy and used as a basis for phylogenetic analyses. Twenty-six petasma characters and 49 thelycum characters were identified. All 16 recognized species of Gennadas and Aristaeomorpha foliacea (outgroup) were included as terminals. Four robust monophyletic clades were retrieved, described and diagnosed as new species groups. The thelycum characters had greater impact on tree topology and supported deeper nodes than did the petasma characters. We hypothesize that features of the thelycum evolved first followed by aspects of the petasma. Relatively more conservative characters include parts of the sternites of the thelycum and of the petasma, while the scuti and protuberances on the thelycum and the shape and subdivisions of the petasma lobes are evolutionarily plastic. We identified two groups of copulatory characters, which are likely coupled functionally and interlinked evolutionarily: (i) the external part of the petasma and the posterior part of the thelycum and (ii) the internal part of the petasma and anterior part of the thelycum. We reconstruct possible mating position during copulation for each of the new species groups presented here. We also present an updated key to genera of Benthesicymidae and key to species of Gennadas .

AbstractThe species of Synophromorpha Ashmead (Hymenoptera: Cynipidae) are reviewed. One new species is described (Synophromorpha kaulbarsi; type locality: Naupan, Puebla, Mexico). The previously described species (S. rubi Weld, S. sylvestris (O.S.), and S. terricola Weld) are redescribed, and a key to species is presented. All species are illustrated for the first time. Synophromorpha sylvestris is designated type-species for the genus and a lectotype is chosen. Hypotheses on the phylogenetic relationships between the species of Synophromorpha are presented.

The genus Myopsalta Moulds is distributed throughout much of Australia. Previous studies have associated several undescribed species with the Myopsalta crucifera (Ashton) species complex. The present study informally divides the cicadas in the genus Myopsalta into two species groups. It provides a revision of the M. crucifera species group, which includes redescriptions of M. crucifera s. str. and M. mackinlayi (Distant). The identity of the latter species is further refined and attributed to material formerly presented under the name Myopsalta atrata (Goding & Froggatt). In addition to the redescriptions, 14 new species belonging to the M. crucifera species group are described, including M. albiventris n. sp., M. bassiana n. sp., M. chrysopedia n. sp., M. gordoni n. sp., M. leona n. sp., M. longicauda n. sp., M. majurae n. sp., M. melanobasis n. sp., M. parvula n. sp., M. platyptera n. sp., M. riverina n. sp., M. septa n. sp., M. umbra n. sp. and M. xerograsidia n. sp. A key to species in the genus Myopsalta is provided. Standard morphological descriptions and descriptions of calling songs unique to each species are included along with a discussion on different song types in the M. crucifera species group.

The micropolydesmoid millipede family Haplodesmidae is here recorded from Cambodia for the first time through the discovery of the first, new species of the genus Eutrichodesmus Silvestri, 1910: E. cambodiensissp. nov. This new species is described from two limestone habitats in Kampot Province, based on abundant material. It is easily distinguished from all related congeners by the following combination of characters: body greyish-brown; limbus roundly lobulate; solenomere partially divided from acropodite by a digitiform lobe, but without hairpad. Brief remarks on the previously-proposed “pecularis-group” are provided and a second group, the “demangei-group”, is established and discussed on the basis of morphological evidence, updating the number of recognised species groups of Eutrichodesmus to two. Detailed morphological illustrations, photographs and a distribution map, as well as remarks on its habitat and mating behaviour of the new species are presented. Furthermore, the current distributions of all 55 presently-known species of Eutrichodesmus are provided and a key to all 23 species that occur in mainland Southeast Asia is given.
