Based on behavioral observations, we report termitophily by the earwig Spirolabia kaja Kočárek, sp. nov. (Spongiphoridae: Labiinae). The new species was found in association with the wood-boring termite Schedorhinotermes sarawakensis (Holmgren, 1913) in a dipterocarp rain forest in Borneo; in addition to being observed in the galleries, termite–earwig interactions were subsequently documented in the laboratory. We found that earwigs and termites communicate by antennation, and we observed no form of targeted mutual or unilateral aggressive behavior. The earwigs responded to the proximity of an experimentally irritated termite soldier by conflict-avoidance behavior based on thanatosis, which seems to be a defensive reaction that may reduce the chance of being attacked by an irritated termite. Based on the analysis of gastrointestinal tract contents, we conclude that S. kaja sp. nov. is an omnivorous species that feeds mainly on plant tissues and fungi but occasionally on arthropod remains. The occurrence of S. kaja sp. nov. adults together with the nymphs (2nd to 4th instars) in the galleries of S. sarawakensis strongly suggests that the earwig can reproduce inside the termite colony. Spirolabia kaja Kočárek, sp. nov. is the first earwig species for which termitophily has been demonstrated.

Recently, drone technology advanced, and its safety and operability markedly improved, leading to its increased application in animal research. This study demonstrated drone application in livestock management, using its technology to observe horse behavior and verify the appropriate horse–drone distance for aerial behavioral observations. Recordings were conducted from September to October 2017 on 11 horses using the Phantom 4 Pro drone. Four flight altitudes were tested (60, 50, 40, and 30 m) to investigate the reactions of the horses to the drones and observe their behavior; the recording time at each altitude was 5 min. None of the horses displayed avoidance behavior at any flight altitude, and the observer was able to distinguish between any two horses. Recorded behaviors were foraging, moving, standing, recumbency, avoidance, and others. Foraging was the most common behavior observed both directly and in the drone videos. The correlation coefficients of all behavioral data from direct and drone video observations at all altitudes were significant (p < 0.01). These results indicate that horse behavior can be discerned with equal accuracy by both direct and recorded drone video observations. In conclusion, drones can be useful for recording and analyzing horse behavior.

A New Species

A new species of Ripiphoridae Gemminger & Harold, 1870, Archaeoripiphorus nuwa gen. et sp. nov., is described and illustrated from a well-preserved impression fossil from the Middle Jurassic Jiulongshan Formation collected at Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China, representing the oldest documented occurrence of the Ripiphoridae described from the Mesozoic era. It shares several characters belonging to two basal ripiphorid subfamilies (Pelecotominae and Ptilophorinae), but it cannot be attributed to either of them and is herein placed as Subfamily incertae sedis. An overall similarity between Archaeoripiphorus gen. nov. and Recent Pelecotominae and the occurrence of wood-boring beetles in the same Formation implies a similar parasitoid host preference in xylophagous beetles for A. nuwa gen. et sp. nov., putting a spotlight on a potential host-parasitoid relationship in the Mesozoic.

Three New Species

Of the 92 Codonoboea species that occur in Peninsular Malaysia, 20 are recorded from the state of Terengganu, of which 9 are endemic to Terengganu including three new species, C. norakhirrudiniana Kiew, C. rheophytica Kiew and C. sallehuddiniana C.L.Lim, that are here described and illustrated. A key and checklist to all the Terengganu species are provided. The majority of species grow in lowland rain forest, amongst which C. densifolia and C. rheophytica are rheophytic. Only four grow in montane forest. The flora of Terengganu is still incompletely known, especially in the northern part of the state and in mountainous areas and so, with botanical exploration, more new species can be expected in this speciose genus.

Five new species of thelotremoid Graphidaceae are described from the Philippines: Myriotrema subviride Rivas Plata, Sipman & Lücking, differing from Myriotrema viride in the more prominent ascomata and transversely septate ascospores; Ocellularia gigantospora Rivas Plata, Sipman & Lücking, differing from O. ripleyi in the uncarbonized, ecolumellate ascomata and the larger ascospores; O. leucocavata Rivas Plata, Sipman & Lücking, differing from O. cavata in the uncarbonized ascomata and the larger ascospores; O. sublaeviusculoides Rivas Plata, Sipman & Lücking, differing from O. laeviusculoides in the erumpent ascomata with black columella; and Thelotrema philippinum Rivas Plata, Sipman & Lücking, differing from Thelotrema suecicum in the stictic acid chemistry. The new combination Ocellularia megalospora (Müll. Arg.) Lücking is also proposed. Three of the new species are based on historical collections from vanished rain forest areas on the island of Luzon and are probably extinct, emphasizing the role of herbaria in documenting biotic diversity from threatened ecosystems.

Abstract— A new species of Phyllanthus with phylloclades endemic to the State of Bahia is described here. Phyllanthus dracaenoides can be recognized for its peculiar habit that resembles a species of Dracaena, a very unusual height of up to 7 m, the plagiotropic phylloclades spirally arranged, and its vermiform cincinni. Notes on its habitat, taxonomic affinity, conservation status, geographic distribution, illustrations, and photographs are provided.

Mangrove Wood

In a survey of the fauna inhabiting fallen wood in Rhizophora-dominated forests of an archipelago of small islands to thesouth of Sulawesi, in Indonesia, four species of limnoriid (Limnoria insulae, L. pfefferi, L. sellifera new species and L.unicornis) were found feeding on the wood. L. sellifera is characterised by a saddle-shaped pleotelson that is smaller thanpleonite 5, transverse rows of teeth-like tubercles dorsomedially on pleonites 2–4 and a uropod with relatively small ex-opod, two rows of pointed tubercles on the peduncle, and one row on the endopod. L. sellifera is the second species ofLimnoria to be found exclusively on mangrove wood. The cephalon and pereon of the four species of limnoriids are anatomically similar, but they differ markedly in features of pleonite 5, the pleotelson and the uropods.

A New Species

Mystacagenia Evans, 1973 is a strictly Neotropical genus of pompilid wasps (Pepsinae: Ageniellini), restricted to rain forest areas. The genus comprises four described species: M. albiceps Evans, 1973 (Peru, Brazil), M. bellula Evans, 1973 (Peru), M. variegata Evans, 1973 (Brazil), and M. elegantula Evans, 1980 (Panama). Mystacagenia is scarce in collections, with only eight specimens registered, all of these females (Evans 1973, 1977, 1980; Cambra 1993; Corro & Cambra 2011).

Seven species of the genus Chiromyza Wiedemann are recorded in Brazil: C. brevicornis (Lindner, 1949), C. enderleini (Lindner, 1949), C. leptiformis (Macquart, 1838), C. ochracea Wiedemann, 1820, C. stylicornis (Enderlein, 1921), C. viridis Bezzi, 1922 and C. vittata Wiedemann, 1820. Herein I describe a new species, Chiromyza raccai sp. nov., based on 88 specimens (41 males, 47 females) from the Atlantic Rain Forest mountains of State of Rio de Janeiro, Brazil, in the city of Miguel Pereira. The new species is distinguished from the related species C. ochracea and C. vittata by the structure of male terminalia. Chiromyza raccai sp. nov. has the distal region of the phallus rounded with two conspicuous apical setae, C. ochracea has the distal surface of the phallus wide and flatness, and C. vittata has the distal surface of the phallus rounded with outer margin rugose.

A new species of the genus Liotyphlops, known from three localities in the states of Alagoas and Bahia, in the Atlantic Rain Forest of Northeastern Brazil, is described. Liotyphlops trefauti sp. nov. is distinguished from all other species of the genus by the following combination of characters: four scales contacting the posterior edge of prefrontal; one scale contacting the posterior edge of nasal, between the second supralabial and the frontal; five scales in the first vertical row of lateral head scales; 22-22-22 scales around body; 520–543 dorsal scales; 499–532 ventral scales; absence of eye spot; and dorsal and ventral color bright yellowish-brown to reddish-brown.
