New species of Charaphloeus Casey, 1916 from the central Amazon area (Brazil) (Coleoptera: Laemophloeidae)

2025-12-19T09:48:24+00:00

In a recent paper, the author identified the characters of Charaphloeus Casey, 1916 (Laemophloeidae) more precisely and described and illustrated ten new species from the lowland natural rain forests of the Amazon basin in Peru (Bremer 2023). In this paper the author is describing six Charaphloeus species from the central part of the Amazon basin near Manaus, Brazil. Species described and illustrated herein are Charaphloeus barclayi sp. nov., C. hurtadoi sp. nov., C. ingratus sp. nov., C. paulus sp. nov., C. vonmartii sp. nov. and C. wallacei sp. nov. Specimens of these new species were collected using light traps from trees of the genus Eschwaleira von Martius, 1828. Two Charaphloeus species described in the first paper from Peru (Bremer (2023) are also occurring in the central part of the Amazon basin (Charaphloeus karneri Bremer, 2023 and C. prosopis Bremer, 2023). They bring up the number of the known species from the central part of the Amazon area to eight species.

A male is described and illustrated for Kaindilagria opposita Telnov, 2022. New records are provided for five poorly known New Guinean lagriine species. A key to species of Gronophora Borchmann, 1916 is presented.

Tychus normandi Jeanell, 1950 and Tychus monilicornis Reitter, 1880 (Staphylinidae: Pselaphinae) in a coastal fen in Mecklenburg-Western Pomerania, Germany – distribution, habitat preference, and phenology of two extremely rare species

2025-12-19T11:10:57+00:00

The minerotrophic coastal paludification fen in the ‘Heiligensee and Hütelmoor’ nature reserve northeast of Rostock, which is aperiodically influenced by brackish water from the Baltic Sea during storm surges, was investigated for two years using pitfall trap series (PTS). Six to eight pitfall traps per PTS were operated from May to October at six sites 2020 and eight sites 2021 with fortnightly emptying. Remarkably, the extremely rare species threatened by extinction Tychus normandi Jeanell, 1950 and T. monilicornis Reitter, 1880 were regularly caught in almost all the sites surveyed. In 2020, 4405 individuals (ind.) of rove beetles were captured in 171 species, including T. normandi in 131 ind. and T. monilicornis in 15 ind. In 2021, 4842 ind. were captured in 143 species, of which T. normandi in 195 ind. and T. monilicornis in 23 ind. Their activity peaked from late May to late June. In 2021, the proportion of ♂ of T. normandi was 83.6 %, that of T. monilicornis 73.9 %. For clarification whether the Tychus species exhibit a salt preference, three soil cores each were analyzed for salinity on each of the eight sites surveyed in 2021 and one reference site in June 2022. The sites investigated had a salt content of 75-867 mg/100 g soil. There was no evidence of a salt preference for either Tychus species; thus, they are apparently halotolerant. The dynamic and constant water supply of intact Phragmites reedbeds in the nature reserve as well as mesoclimatic effects may be crucial for the occurrence of both hygrophilous species. Salt grassland management, here late summer mowing, reduces the habitat suitablility for both species.

Brachynopterus rufulus Bedel, 1898 rediscovered almost 130 years after its original description and first report for Morocco (Coleoptera, Carabidae, Lebiinae)

2025-12-19T12:31:33+00:00

An enigmatic ground-beetle species Brachynopterus rufulus Bedel, 1898 were collected in Morocco for the first time. Detailed redescription of the genus and species were made. Its taxonomic position within the subfamily is discussed. Photographs of the habitus and details of the structure are provided.

A new species of Paha Dajoz (Coleoptera: Zopheridae: Colydiinae) from late Eocene Rovno amber

2025-12-19T13:49:09+00:00

Based on a well-preserved specimen in Eocene Rovno amber, a new species Paha groehni sp. nov. (Coleoptera: Zopheridae) is described and illustrated. The new species differs from extinct species from Baltic amber, Paha vanivanitatum Alekseev & Bukejs, 2024, in distinctly smaller body size, as well in characters of pronotal shape and sculpture, first at all in posteriorly curved pronotal carinae and prominent anterior pronotal angles. The studied inclusion represents the first species of a colydiine beetle described from Rovno amber and extends palaeohistorical distribution limits of the genus further eastwards.

First representative of Cacotemnus LeConte (Coleoptera: Ptinidae) from Eocene fossil resin

2025-12-19T14:27:25+00:00

A new fossil deathwatch beetle, Cacotemnus succinophilus sp. nov., is described on the basis of a single adult inclusion in Baltic amber. The new species is compared with morphologically similar anobiine species from this fossil resin and with closely related extant beetles.

A new species of Serropalpus Hellenius (Coleoptera: Melandryidae) from Rovno amber, with key to extinct species of the genus

2025-12-29T08:03:49+00:00

Based on a well-preserved specimen in Eocene Rovno amber, a new species Serropalpus groehni sp. nov. (Coleoptera: Melandryidae) is described and illustrated.
The new species differs from extinct congeners in having longer metatibial spur, weakly notched apex of mesosternal process, discernible elytral furrows, and outer edges of meso- and metatibiae with 8–9 oblique rows of bristles. An updated key to fossil Serropalpus species, known from Baltic and Rovno ambers, is also provided.

Furthermore, a previously unevaluated diagnostic character is identified and shown to have taxonomic value at the generic level, distinguishing Brevipterus Y. Yang, H. Liu & W. Zhao, 2022 from Sanaungulus.
