Sucinoptinus brevipennis sp. n. M a t e r i a l. Holotype. Possibly male. SIZK D-2295, Dubrovitsa, Rovno amber, Late Eocene (fig. 1, 2). Syninclusions: Mycetophilidae, Acari (Parasitengona), numerose stellate hairs. D e s c r i p t i o n. Length: 1.6 mm. Slender, parallel-sided; color brownish-piceus (fig. 1, 2). Head finely punctuated and pubescent; interantennal space narrow and rather flat; eyes hemispherical, quite prominent and finely faceted. Antennae eleven segmented, slender and long, slightly longer than the elytral length, covered with semierect pubescence; antennomere proportions according to the formula: 7–3–4–4–4–4–4–4–4.5–5–8.5 (fig. 1, 2). Pronotum slightly longer than wide and wider than a single elytron; apical margin widely convex anteriorly, partially concealing the head; sides slightly rounded, only slightly constricted near the base, moderately convex at the disk and showing a quite apparent transversal depression in the posterior third; surface irregularly sculptured in the anterior third, with round, small tubercles in the disk, and with small elongated tubercles in the posterior third transversal depression; pubescence formed by short semi-recumbent hairs evenly distributed (fig. 1, 2). Legs short and robust covered with short recumbent pubescence; tarsi relatively long, nearly as long as tibiae; mesotarsi with tarsomere proportions according to the formula: 5–1.5–1.5–1–5. Scutellum triangular, as long as wide. Elytra subparallel and short, only slightly longer than twice the length of the pronotum; humeri prominent; elytral surface serially punctuated by elongated strial punctures, leaving an interstriae interval about twice wider as the width of the striae; pubescence formed by semirecumbent short setae inserted in the punctures (with a length similar to that of the puncture) and erect and moderately long (somewhat longer than those of the punctures) setae inserted in the intervals (fig. 1, 2). D i a g n o s t i c c h a r a c t e r s. S. brevipennis is similar to the previously known species, S. bukejsi and S. sucini in having the same general structure of the prothorax, but differing from these species in having much shorter elytra, with a proportion length of the pronotum (LP)/length of the elytra (LE) = 2.1. This clearly differs from the proportion found in S. sucini (LE/LP = 2.7), in S. bukejsi (LE/LP = 2.6, according to measurement made on the pictures sent by V. Alekseev) and in S. rovnoensis, described above, where LE/LP = 3.0. E t y m o l o g y. The specific name refers to the shortness of the elytra, which is the most typical feature of the new species., Published as part of Bellés, X. & Perkovsky, E.

Sucinoptinus ? sp.? M a t e r i a l. SIZK K-25483, Klesov, Rovno amber, Late Eocene. The inclusion contains a spider beetle, with only the ventral and right lateral parts preserved. Moreover, the remains are affected by a sort of a cloudy secretion (fig. 1, 5) that makes more difficult the observations. However, the lateral part of the prothorax showing a characteristic depression near the base in the dorsal part, suggests that it belongs to the genus Sucinoptinus., Published as part of Bellés, X. & Perkovsky, E.

Sucinoptinus rovnoensis sp. n. M a t e r i a l. Holotype. Possibly female, only thorax and elytra present. SIZK UA-335, Rovno amber, Late Eocene. D e s c r i p t i o n. Length (pronotum plus elytra): 1.5 mm. Relatively robust, roundedsided; color brownish (fig. 1, 1). Pronotum slightly wider than long and neatly wider than a single elytron; apical margin widely convex anteriorly; sides only slightly rounded, practically not constricted near the base, moderately convex at the disk and showing a quite apparent semicircular depression in the posterior third; surface covered with dense tubercles, oval and large, specially within the semicircular depression, where they are almost as large as half the size of the scutellum; pubescence formed by short semi-recumbent hairs inserted between the tubercles (fig. 1, 1). Scutellum triangular, as long as wide. Elytra slightly roundsided and relatively short, 1.35 as long as wide, but clearly longer than twice the length of the pronotum; humeri prominent; elytral surface serially punctuated by elongated strial punctures, leaving an interstriae interval about twice wider as the width of the striae; pubescence formed by recumbent short setae inserted in the punctures (with a length somewhat longer that the puncture), semirecumbent and moderately long (somewhat longer than those of the punctures) setae inserted in the intervals and evenly distributed, and erect and still longer setae sparsely distributed in the interstriae of the apical part (fig. 1, 1). D i a g n o s t i c c h a r a c t e r s. The new species is similar to S. bukejsi, from amber inclusions found at Yantarny (formerly Palmnicken) in the Kaliningrad region, Russia (Alekseev, 2012) in having the same general structure of pronotum and elytra, but differing from this species by the morphology of the pronotum, with sides only slightly rounded and practically not constricted near the base, whereas that of S. bukejsi has the sides well rounded leaving a slight but clear constriction near the base. Moreover, the semicircular depression of the posterior third of the pronotal disk of S. rovnoensis is not present in S. bukejsi, which shows a regularly convex pronotal disk, with a depression in the posterior third only slightly marked. The large tubercles forming the surface of the semicircular depression of S. rovnoensis are neither present in S. bukejsi, which shows a type of tubercles smaller and evenly distributed. S. sucini Bellés et Vitali (2007) also has a semicircular depression in the posterior third of the pronotal disk, but it is narrower and the tubercles of the sculpture within it are much smaller and rounded in shape.

Sucinoptinus sp.? M a t e r i a l. Two specimens, SIZK UA-284, Rovno amber, Late Eocene and SIZK K-6067, Klesov, Rovno amber, Late Eocene. The inclusion labeled UA-284 contains a well recognizable spider beetle belonging to the genus Sucinoptinus sp. The specimen is practically complete except the antennae and parts of the legs, but its orientation in the inclusion makes difficult a specific identification. However, it looks like a S. rovnoensis, but with the typical semicircular depression on the posterior third of the pronotum somewhat deeper, and with the strial punctures of the elytra somewhat broader, which leave the interstriae intervals only slightly wider than the punctures (fig. 1, 3). The specimen SIZK K-6067 is also practically complete, but again the orientation makes difficult a complete identification. It looks very similar to the specimen UA-284, but with the pronotum slightly more transversal and the elytra somewhat shorter (fig. 1, 4)., Published as part of Bellés, X. & Perkovsky, E.

Ptinus bertranpetiti sp. nov. (Coleoptera: Ptinidae) is described from Socotra Island. The practical absence of secondary sexual dimorphism and the structure of the aedeagus, slender and subsymmetrical, suggest that the new species must be placed in the subgenus Gynopterus Mulsant & Rey, 1868. The most peculiar characteristics of P. bertranpetiti sp. nov. refer to the aedeagus and the elytral pubescence, both with features that are unparalleled in other species of the subgenus Gynopterus.

Immunoreactivity against peptides of the allatostatin family having a typical YXFGL-NH2 C-terminus has been localized in different areas of the central nervous system, stomatogastric nervous system and gut of the cockroach Blattella germanica. In the protocerebrum, the most characteristic immunoreactive perikarya are situated in the lateral and median neurosecretory cell groups. Immunoreactive median neurosecretory cells send their axons around the circumesophageal connectives to form arborizations in the anterior neuropil of the tritocerebrum. A group of cells in the lateral aspect of the tritocerebrum project to the antennal lobes in the deutocerebrum, where immunoreactive arborizations can be seen in the periphery of individual glomeruli. Nerve terminals were shown in the corpora allata. These terminals come from perikarya situated in the lateral neurosecretory cells in the pars lateralis and in the subesophageal ganglion. Immunoreactive axons from median neurosecretory cells and from cells positioned in the anteriormost part of the tritocerebrum enter together in the stomatogastric nervous system and innervate foregut and midgut, especially the crop and the valve between the crop and the midgut. The hindgut is innervated by neurons whose perikarya are located in the last abdominal ganglion. Besides immunoreactivity in neurons, allatostatin-immunoreactive material is present in endocrine cells distributed within the whole midgut epithelium. Possible functions for these peptides according to their localization are discussed. © 1998 Wiley-Liss, Inc., This work was supported by the DGICYT, Spain (project PB95-0062) (X.B.) and the Agricultural and Food Research Council of Great Britain (grant AG68/022), the Leverhulme Trust (F/476/Q), the Royal Society, and the Central Research fund of the University of London (A.T.).

Inventory-based approaches (i.e., those that directly relate species richness to explanatory variables) do not work on the medium and local scale that was studied in this paper; even when ecologically-meaningful environmental predictors were used. The use of an alternative approach (Taxon-based diversity mapping) is proposed. This approach starts by modelling the probability of occurrence of twelve target endemic species using environmental variables as predictors. Next, it projects the probability of occurrence from 48 sampled sites to a grid of 532 1-km2 units. Finally, the approach estimates endemic species richness at these 532 1-km2 units by overlapping the twelve maps inferred. We also propose a new approach whose purpose is to detect possible false absences and unstable presences. These doubtful observations were excluded from ecological niche modelling. In addition to species richness, the patterns experienced by species composition were analysed. Species composition experienced strong changes (i.e., large turnover), while species richness remained constant. This stasis in species richness is neither related to low environmental variability (both the biotic and abiotic scenarios are diverse) nor to the lack of species-environment relationships (not only species composition but also species-specific responses are correlated with environment). The area studied is environmentally diverse and species turnover of the macroinvertebrate community was moderate to large. Species composition was significantly correlated with environment (minimum temperature). The predicted number of target endemic species per cell in 92% of the studied area fell between 3 and 5. Therefore Taxonbased diversity mapping has been confirmed as a valid alternative to conventional inventory-based diversity mapping. Additionally, the new procedure proposed here for dealing with noisy presence/absence data produces more accurate distributional maps of individual species., The authors thank Conselleria de Medi Ambient del Govern de les Illes Balears and Caixa de Balears “Sa Nostra” for their financial support.
