Termitophilous rove beetles in Australia encompass diverse genera and species from several tribes in Aleocharinae. While some taxa have been well-documented, others remain poorly known due to the ...scarcity of available material. The existing knowledge of Austrospirachtha Watson for instance, is based solely on Austrospirachtha mimetes, described from two specimens collected in an old termite mound. The genus is known for its highly developed physogastry and potential mimicry adaptations. Herein, we present the description of a new species, Austrospirachtha carrijoi sp. nov., representing the second known species for the genus.
A systematic review of the marine littoral
Cafius bistriatus
(Erichson) along the eastern Pacific and the western Atlantic coasts including the Caribbean Sea is presented based on morphological and ...molecular (
COI
and
28S
) characters. Specimens of the
Cafius bistriatus
species complex
C. bistriatus
,
C. rufifrons
Bierig, and
C. sulcicollis
(LeConte) are similar to each other, including the form and structure of the aedeagus, and they can be treated as cryptic species. Detailed micromorphological characters (SEM) and molecular analyses support the validity of these three species. Intraspecific genetic divergence of
COI
using uncorrected p-distance among individuals of
Cafius bistriatus
ranged from 0% to 1.56%, while interspecific divergence among three species ranged from 4.90% to 14.59%. All three species were each supported as a single lineage using
COI
and
28S
on both parsimony and maximum likelihood trees. Morphological characters among
C. bistriatus
,
C. rufifrons
, and
C. sulcicollis
are compared.
Cafius bistriatus fulgens
Frank is synonymized under
C. bistriatus
and
Cafius bistriatus
is redescribed with illustrations of diagnostic characters.
Rove beetles belonging to the genus Corotoca (Staphylinidae: Aleocharinae) are termitophiles exclusively found in nests of Constrictotermes (Isoptera: Termitidae). We observed the reproductive ...behavior of Corotoca melantho and C. fontesi during host (C. cyphergaster) foraging events. The reproductive behaviors of both species are similar. The variables collected for analysis were distance traveled, the time of larval deposition, nest return time, and locomotion speed. The fact that the female stops in the middle of the foraging trail to deposit the larva leads to a discussion of how its physiological or voluntary mechanisms function to determine the correct stopping time and the importance of speed when returning to the nest as a strategy to avoid predation. This study provides new information concerning the life cycle of Corotoca spp., although complete understanding of host-termitophile relationships, their evolutionary history, and the significance of viviparity will require additional studies.
Diochus Erichson is a worldwide rove beetle genus with species found in forest floor litter. Three species of Diochus were recently collected in northern Brazil, one of them considered as new and ...herein described. Within Diochus nanus-group, D. cleidecostae sp. nov. differs from D. apicipennis Cameron, D. nanus Erichson and D. perplexus Cameron by the aedeagus with clearing trifurcate apex of parameres; and differs from D. parvulus Kraatz by the three apical long setae of parameres distributed on ventral and dorsal lobes. A previous key to the D. nanus-group is updated to include the new species. Here we also report for the first time D. santacatarinae Irmler and D. parvulus from Pará state, Brazil. Finally, a discussion about the sexual dimorphism on sternum VIII is also provided for the genus.
Three new species of Nazeris Fauvel, 1873 from the Jiuwan Mountain, Guangxi, China, are described and illustrated: N. jiuwanensis, sp. n., N. qingshuius, sp. n. and N. yangmeius sp. n. An ...identification key to the Nazeris species in Guangxi is provided.
Xenogaster Wasmann is a Neotropical genus of termitophilous rove beetles with 11 known species. During recent surveys in Southeastern Brazil, we collected a new species of this genus, Xenogaster ...lugens Pires-Silva and Zilberman sp. nov., herein described. This new species is known only from an intermediate stage of development, which prompted a discussion about the range and underestimation of the phenomenon of post-imaginal growth in Termitogastrina (Corotocini). A redescription of X. pilosula Seevers, and comparisons between its stenogastric and physogastric stages are also presented and used in the final discussion on the taxonomical and evolutionary significance of this phenomenon under the frame of the knowledge of post-imaginal growth in the subtribe and also Corotocini in general.
This study describes a new rove beetle species, Naddia flavipes sp. nov. from southern China and provides additional morphological knowledge on Naddia hainanensis Yang & Zhou 2010. Line drawings and ...color illustrations of adult structures and genitalia are provided for both species.
A new species of the genus Leptobium Casey (Coleoptera: Staphylinidae: Paederinae) from Israel is described, illustrated, and distinguished from congeners: Leptobium korotyaevi sp. n. (Tel-Aviv, ...Shoham). New and additional distribution data for eight species in the Middle East and adjacent regions are reported. A checklist and identification key of Leptobium of Israel is provided. The genus is now represented in Israel by seven species.
