A New Species

Pseudolebinthus is an intriguing genus of the tribe Xenogryllini with a distribtuion restricted to southeast Africa and characterized by unique morphological features such as asymmetrical male forewings and harp veins shaped as elongated balloons. It is sister group to the widely distributed genus Xenogryllus and has been known by two species, P. africanus Robillard, 2006 and P. whellani Robillard, 2006. The genus was initially diagnosed based exclusively on male morphological features. In this study, we add a new species to the genus, P. gorochovi Robillard sp. nov. and revise the diagnostic features using both male and female characters. We also update identification keys for the species of the genus.

First Time

The validity of Genolopa Linton, 1910 has been controversial because the observation of presently recognized critical diagnostic morphological features (spines in the genital atrium and a bipartite, anteriorly spined terminal organ) were omitted from the original diagnosis, and these features were not universally appreciated as important diagnostic features until 2008. Modern taxonomists have been further challenged by inappropriate fixation techniques that have resulted in various interpretations of morphological features. Consequently, named species in the genus have fluctuated among other monorchiid genera depending on various interpretations by taxonomists, and a modern consensus on classifying these species is lacking. This study combines a molecular approach with modern conventional morphological techniques to investigate the validity of Genolopa as a lineage within the Monorchiidae. New morphology and molecular sequence data from the type-species of Genolopa were studied, and two new species in the genus were described, Genolopa vesca n. sp. and Genolopa minuscula n. sp. Interrelationships among the Monorchiidae were explored using Bayesian inference analysis of the partial 28S rDNA fragment, incorporating three species of Genolopa for the first time. The phylogenetic analysis revealed that the genus represents a natural lineage, supporting the presence of spines in the genital atrium in conjunction with a bipartite and anteriorly spined terminal organ as key features of the generic diagnosis. This study also provides for the first time partial 28S rDNA data for Postmonorchis orthopristis, Lasiotocus trachinoti, Lasiotocus glebulentus, and an unidentified species of Lasiotocus.

Crustose Lichen

The crustose lichen genus Maronea A. Massal (Fuscideaceae) comprises about 12 species worldwide (Kantvilas 2001, 2004). The easily recognized, diagnostic features of this group of lichens are the lecanorine apothecia, Teloschistes-type ascus, and numerous spores per ascus, and these have contributed to a very stable generic concept over the years. As in many genera of lichenized fungi, however, differing species concepts have led to confusion over how many taxa are recognized. Many species, and varieties and forms of Maronea that were described on the basis of minor morphological features have since been synonymized (e.g. Harris 2006; Magnusson 1934).

The morphology of pollen grains of 16 species from the <em>Rosa </em>L. genus were studied (i.e. <em>R. agrestis</em>, <em>R. canina</em>, <em>R. dumalis</em>, <em>R. gallica</em>, <em>R. inodora</em>, <em>R. jundzillii</em>, <em>R. kostrakiewiczii</em>, <em>R. majalis</em>, <em>R. micrantha</em>, <em>R. mollis</em>, <em>R. pendulina</em>, <em>R. rubiginosa</em>, <em>R. sherardii</em>, <em>R. tomentosa</em>, <em>R. villosa</em>, and <em>R. zalana</em>). The material came from 16 native localities of those species in Poland. The measurements are based on at least 30-50 randomly selected, fully developed pollen grains per specimen. In total, 500 pollen grains were examined. They were analysed for 13 quantitative features of pollen grains and exine sculpturing and the following qualitative traits: outline, shape, "operculum" structure. The diagnostic features of pollen grains of studied species were: length of polar and equatorial axes and length of ectocolpi. The above-mentioned pollen grain morphological features make isolation of one species possible: <em>R. gallica</em>. <em>R. gallica </em>is distinguished for its highest values of the length of polar and equatorial axes, and the length of ectocolpi. The obtained analytical results of operculum and exine sculpture features, considered as diagnostic, corroborated only slightly their priority significance for the isolation of the examined species and sections. The collected data failed to confirm fully the current taxonomical division of the <em>Rosa </em>genus into sections (only section <em>Gallicanae</em> from <em>R. gallica </em>is isolated) as well as consanguinity relationships between the examined species from the <em>Caninae </em>section. On the dendrogram, both species closely related with each other as well as those from other developmental lines were found in the same group. These equivocal results are by no means surprising because the <em>Caninae </em>section is the most polymorphic group in the <em>Rosa </em>genus, and contemporary <em>Caninae </em>are of the nature of a swarm of <em>R. canina </em>hybrids as a link combining all taxons of the section.

Three New Species

The robber fly genus Wilcoxia is revised based on external morphological features of adults. For each species the following is provided: type specimen information, diagnostic features, description, natural history including associated prey data, and geographical distribution (derived from georeferenced localities for both examined specimens and literature records). A key to adults of Wilcoxia, supplemented with photographs of habitus and selected morphological features, is included. The genus comprises eight species, distributed primarily in the southwestern United States. Three new species are described: W. apache (type locality: New Mexico, Quay County, Apache Canyon), W. flavipennis (type locality: Arizona, Pima County, Organ Pipe Cactus National Monument), and W. forbesi (type locality: New Mexico, Doña Ana County, 1 mi. NW Tortugas Mt.). There appear to be two reasonably well-defined species groups (cinerea and martinorum groups, with four species in each), based on structural features, seasonality and natural history. Identified prey items (for W. apache, W. forbesi and W. martinorum) include representatives from Hemiptera (eight families), Coleoptera (one family), Hymenoptera (five families) and Diptera (10 families). A discussion on the structural heterogeneity of Wilcoxia and a history of its classification are provided.

The taxonomy of the family Desmodoridae (Nematoda: Desmodorida) is partially revised based on morphology. The diagnoses of the Desmodoridae and the subfamilies Desmodorinae and Spiriniinae are emended to accommodate re-analyzed morphological features. Eight known species are redescribed and the implication of the new findings for the taxonomy of the group is discussed. Amphispira and Metadesmodora are confirmed as genera inquirendae. Alaimonema and Sigmophoranema, and their corresponding type species, are proposed as inquirendae due to poor descriptions of the type material. The other three species of Sigmophoranema are transferred to the genus Onyx because they bear the diagnostic features of this group: spear-like dorsal tooth and s-shape precloacal supplements. Echinodesmodora, Paradesmodora and Stygodesmodora are transferred to the Spiriniinae based on the absence of a head capsule and on the amphidial fovea being surrounded by cuticle striation. Paradesmodora toreutes is transferred to the genus Acanthopharyngoides as A. toreutes comb. nov. The genus Onepunema does not fit in the family Desmodoridae because of diorchic males; thus, it is regarded as taxon incertae sedis. Lists of valid genera for the two subfamilies are provided. A dichotomic key for the identification of the 14 genera within the Spiriinae is provided.

A description of the hitherto unknown larvae of Drusus radovanovici septentrionis Marinković-Gospodnetić, 1976 and Drusus croaticus Marinković-Gospodnetić, 1971 is given. The most important diagnostic features enabling separation from larvae of the other Drusinae are listed and illustrated. Larvae of D. croaticus are distinguished by the combination of specific morphological features (e.g. shape of head and pronotum, the absence of mandible teeth, the absence of prominent, black median setae on frontal margin of pronotum etc.). Besides the above mentioned, larvae of D. radovanovici septentrionis are primarily distinguished by distinct spinules on the head capsule. Some ecological notes are given and the life cycle of both species is discussed. Regarding the feeding behaviour, both analyzed species seem to be predominantly grazers. Both species were recorded in different spring types in the Dinarides. D. radovanovici septentrionis is known only from three springs in Bosnia and Herzegovina (springs of the Rivers Pliva, Bistrica and Sturba), while D. croaticus was recorded in 19 different springs in Croatia. Additionally, all Trichopteran species recorded from the sampled springs are listed.

Eggs of 14 species within two subfamilies (Edessinae and Pentatominae, tribes Carpocorini, Nezarini, Pentatomini, Procleticini, and one unplaced species) of neotropical pentatomids were studied with scanning electron microscopy, and their external morphology was characterized in detail (chorion surface, operculum, and aero-micropylar processes). Eggs of these species have similar characteristics to those already described for other pentatomids. Most of them are barrelshaped, except in Edessa meditabunda (with spherical eggs) and Odmalea basalis (whose eggs have flattened lateral faces). A “T”-shaped ruptor ovis is present in all studied species; eclosion line at the operculum rim may be visible or not. Average size of eggs (length x width) ranges from 0.9 ± 0.12 x 0.9 ± 0.05 mm (Euschistus picticornis) to 2.1 ± 0.12 x 1.7 ± 0.10 mm (Chinavia erythrocnemis); the number of the aero-micropylar processes ranges from 10 (C. musiva) to 86 (C. obstinata). Chorion surface has a variable aspect: eggs of Euschistus spp., Loxa deducta, and Pallantia macunaima have the spinose chorion type; C. erythrocnemis, C. longicorialis, C. obstinata, C. pengue, and Grazia tincta have a reticulate chorion; C. musiva, O. basalis, and E. meditabunda have a granulated chorion; and Thyanta humilis has a salebrose chorion type. All the species with described eggs in the Edessinae share the same diagnostic features. In Pentatominae, we did not identify shared characters among the species at subfamily or tribe level. Chorion sculpture pattern and aero-micropylar processes shape, as well as number, are diagnostic features at genus level; however, a few species could be identified in the egg stage.

The aim of our researches was exposure of biomorphological specialities of sorts Chrysanthemum × hortorum introduced in conditions of Right Bank Forest-steppe of Ukraine. Researches were done during vegetative season of 2016 in conditions of National Dendrological park ″Sofiyivka″ NAS of Ukraine. The objects of our researches were sorts Chrysanthemum × hortorum: 'Мolfretta Pink', 'Linda', 'Daphne White', 'Venus Galatі', 'Okura Red', 'BelgoLilak', 'Molfretta Orange', 'Ida', 'Distino Orange', 'Paularo Lilac', 'Ceus', which are groun on research-introductive grounds. As a result of researches we found out that vegetative period lasts 211-240 days, bloomiing period continues 31-68 days. The sorts pass all phases of evolution except phase of bearing fruits in introduction in Right Bank Forest-steppe of Ukraine. The plants have a compact spherical and hemispherical shape of the bush, the height of which varies from 23.1 to 36.1 cm, a dissected leaf blade, a variety of inflorescences, a long flowering period, and are characterized by a wide color range of inflorescences. The morphological features of flowers, inflorescences, leaves and shrubs listed above are diagnostic features that make it easy to determine their variety.
