Twenty-two new species of Zadbimyia, a new genus of the tribe Asynaptini, are described from Costa Rica, the first new descriptions of Neotropical Porricondylinae (Cecidomyiidae) in modern times. The new species are: Zadbimyia aberrans, Z. anniae, Z. artborkenti, Z. browni, Z. carolinae, Z. costaricensis, Z. dubia, Z. elenae, Z. elviae, Z. holdenae, Z. inornata, Z. lasalturas, Z. marcoi, Z. mem...

A,(T) = [L9(T) ® LQ(T)]IK where K is the kernel of the convolution operator c:Lp(S>LQ(T)->C0(T) by (f®g)(y)(f* g)(y)-4*(r) is the /?-Fourier algebra which was introduced by Figa-Talamanca in [6] where it was shown that ^ ( T ) * isisometrically isomorphic to MP(T), the bounded, translation invariant, linear operators on LP(T), Herz [11] showed that AP(V) is a Banach algebra under pointwise mult...

Although salamanders are characteristic amphibians in Holarctic temperate habitats, in tropical regions they have diversified evolutionarily only in tropical America. An adaptive radiation centered in Middle America occurred late in the history of a single clade, the supergenus Bolitoglossa (Plethodontidae), and large numbers of species now occur in diverse habitats. Sublineages within this cla...
