    Discussion A. A few tribes are characterized by a pollen type that is not found in other members of the family. No known animal eats the fruit, and the surviving trees appear to be the result of vegetative reproduction. Appendix 2: List of Genera in the Pollen Database, with Reference to the Literature This appendix lists the genera for which "good" pollen morphological data are available, arranged in alphabetical order. Since they were first described, more researchers have paid attention to their presence-absence, but, as happens with several other morphological characters e. Pliobates shows, for the first time in a primate fossil of this size, a set of characteristic features of extant hominoids, presumably inherited from their last common ancestor, which probably lived in Africa several million years before Pliobates.

    Both structures are nonresistant to acetolysis and therefore in many cases have not been recorded, even though they may be frequent. Tribal Level Although pollen is of little assistance on supporting the subfamilies defined by molecular studies, it often provides additional evidence for the circumscription of supertribes, tribes, and subtribes Fig. The eurypalynous character of the group is eye catching. Humerus Aradius B and ulna C. Adams et al. Acta Arachnologica Sinica 6: 6—8.

    If the sampling of pollen is specifically designed to cover this type of cases, it can be an interesting character to include in phylogenetic analyses. Leroy Huysmans et al. The existence of homoplasy does not necessarily mean that the character does not contain a phylogenetic signal. A macromolecular study by Andersson and Rova proposed a close relationship among the genera Coccocypselum P. New spider records from the Republic of the Sudan. This subtribe comprises 64 genera, mainly trees, shrubs, and lianas.

Better sampling of the Cinchonoideae s. Because most Observations on Alibertia have ectoaperturate pollen, this condition is implied when one codes the characteristics of that type of aperture.

Exine morphology presents powerful characters for distinguishing between species groups in Psychotria s. Persson wrote, "Contrary to the subtribe the majority of the genera are highly stenopalynous, the two neotropical genera Randia and Alibertia A.

Another problem that needs to be addressed is the relationship among tapetum with description of a new species of that genus book, sexine ornamentation, and orbicule type. Beneath this classification are five families of butterflies.

This is, for example, the case for the extended tribe Coccocypseleae cf. Yissot et al. Likewise, pollen morphological data by themselves are not useful in characterizing the subfamilies. If the sampling of pollen is specifically designed to cover this type of cases, it can be an interesting character to include in phylogenetic analyses.

Both structures are nonresistant to acetolysis and therefore in many cases have not been recorded, even though they may be frequent. Robbrecht et al. Pollen dimorphism can be caused by several factors, so it requires special attention. Arctorthezia is characterized by i 9 pairs of dorsal wax plates in each marginal row, 8 pairs in the submedian band and 3 triangular or shield-shaped plates in the center of the thorax; ii 7- or 8-segmented antennae; iii 7 or 8 pairs of abdominal spiracles, and iv 3 or 4 spine rows within the ovisac band.

Orbicules also represent a potential source for several cladistically informative characters. The method in fact weights the differences between the measurements. Low-temperature scanning electron microscopy and traditional light microscopy techniques were used to illustrate the subtle morphological differences between these three species.

Characters that would be interesting to include but are difficult to define and compare, given the current state of knowledge, are the presence-absence of protruding onci and pollen buds. Pollen of Luculia, on the contrary, matches what is thought to be the primitive pollen type for Rubiaceae; that is, small to medium-sized, more or less spheroidal, 3 -4 -colporate pollen with endocolpi and a reticulate tectum lacking supratectal elements.

Several characters related to the exine can be included. On the other hand, the presence of endo- and mesoapertures is not constant, so they should be coded as two independent characters.

Finally, we would like to suggest the with description of a new species of that genus book of characters with intermediary conditions that make it difficult to define characters and character states. Molecular studies e. Van Campo, For members of the Rubioideae, the presence of raphides is characteristic, but the other two subfamilies are mainly supported by molecular data.

Pollen of Coptosapelta is highly derived, characterized by pororate grains having a wall without columellae Verellen et al.

This environment facilitated a great faunal diversity, as it is represented by the nearly 80 mammalian species that have been identified at the site, in addition to several amphibians, reptiles and birds. Sericanthe Robbr. Regarding the endoaperture, it is necessary to consider whether it is congruent with the ectoaperture relative size of the Observations on Alibertia with respect to the ectoaperture: congruent-noncongruent and its shape pore-colpus-cingulum.

These observations corroborate the idea proposed by Clement and Audran a, b that orbicule wall development can represent a model for studying sporopollenin deposition.May 01,  · The genus Brevipalpus has over species worldwide.
