AbstractA new trichodorid species, Trichodorus gilanensis n. sp. is described from a forest park in northern Iran. The new species is characterised in the male by three ventromedian cervical papillae with the anterior two at the level of the onchiostyle region, the posterior-most ventromedian procloacal supplement (SP1) at the level of the retracted spicule head, spicules smooth and manubrium continuous with shaft, and in the female by large triangular vaginal sclerotised pieces close to one another in lateral view, a barrel-shaped vagina, a transverse slit-like vulva in ventral view and a slightly swollen tail region. Three other trichodorid species found, T. primitivus, Paratrichodorus porosus and P.tunisiensis represent new records for Iran.

Bakernema enormese sp. n., collected from rhizosphere of forest wood trees in Muong Phang, Dien Bien Province (north Vietnam) is described and illustrated. The new species is characterized by large body size and stylet. In general, this new species is close to two existing species of the same genus, B. inaequale and B. dauniense by cuticle structure in transparent membranous projections which appear in lateral view as spine-like structures on each annulus. These structure arranged into several rows along the body. In morphology, the new species differs from B. inaequale and B. dauniense  by body and stylet length, i.e. 609–842 µm and 143.5–150 µm vs. 391–578 µm and 59–74 µm for B. inaequale and vs. 391–461 µm and 65–74 µm for B. dauniense. In addition, new species can be distinguished from B. inaequale by the longer membranous projection, 8–12 vs. 6–10 µm and vagina shape, curved vs. sigmoid. From B. dauniense, the new species differs by the much longer membranous projection, 8–12 vs. 1.4–2.2 µm and less number annules between vulva and tail end (RV), 3–4 vs. 7.8 annules. The presence of Criconema (Nothocriconemella) graminicola Loof, Wouts & Yeates, in Vietnam with morphometrics, illustrators and remarks given.

Three new species of Ceraclea (Leptoceridae) from Southeast Asia are described and illustrated: Ceraclea (Athripsodina) trisdikooni n. sp. from Myanmar, C. (A.) thongnooi n. sp. from Thailand and Myanmar and C. (A.) thongpongi n. sp. from Laos. Ceraclea trisdikooni n. sp. is distinguished from other species by its inferior appendages recurved ventrad nearly 180° apically. The apex of the basal segment of each inferior appendage is more pointed. In ventral view, each inferior appendage of the new species has an obvious basoventral lobe with numerous long setae. Ceraclea thongnooi n. sp. is distinguished from those by inferior appendages that are each shaped like a seahorse head both in lateral view and ventral view. Ceraclea thongpongi n. sp. is distinguished from other species by the rectangular preanal appendages. In dorsal view, the apical end of segment X is oval and notched apically; in ventral view, the subapicodorsal lobe of each inferior appendage is rounded and straight.

Oxyethira Eaton, 1873 is one of the most diverse genera of Hydroptilidae, comprising over 240 species distributed in all biogeographical regions. Here three new species of Oxyethira (Trichoglene) Neboiss, 1977 are described and illustrated from male specimens collected in New Caledonia: O. (Trichoglene) hamus sp. nov., recognized by the hook-shaped apex of the long inferior appendages in lateral view and by the posterior margin of segment IX with a trilobed appearance in ventral view; O. (Trichoglene) rectangulata sp. nov., recognized by the rectangular shape of the inferior appendages, which are totally fused and with two pairs of small setae on the inner face; and O. (Trichoglene) spiralis sp. nov., recognized by the strongly curvilinear shape of the subgenital process in dorsal and lateral views and by the long process spiralling around the ejaculatory duct at the phallus apex.

AbstractAdults of the dusk-flying and rotting wood-nesting bees Megalopta genalis and/or M. ecuadoria were collected at Barro Colorado Island, The Smithsonian Tropical Research Institute (BCI, STRI), Panama and La Selva, Costa Rica, and examined for nematodes. Nematodes were recovered as dauer juveniles from the Dufour's gland of female bees and aedeagus of male bees. Adult nematodes isolated from M. genalis (BCI and La Selva) and M. ecuadoria (BCI) were successfully cultured and kept in the laboratory. All three populations were used for morphological observations and molecular analyses and were identified as a new species that is described herein as Acrostichus megaloptae n. sp. It is characterised by its stomatal morphology, possession of six triangular cuticle flaps covering stomatal opening, duplicated cheilo- and gymnostomatal walls, large dorsal tooth and sclerotised ventral stegostomatal ridges, female with vulval flap, male spicule and gubernaculum morphology, i.e., relatively straight spicule with oval-shaped manubrium, rounded flap-like rostrum and separated and strongly ventrally curved spicule with bifurcate tip, gubernaculum L-shaped in lateral view and anchor-shaped in ventral view, and filiform tail of both sexes. Sequences from the three A. megaloptae n. sp. geographical/host isolates were not significantly different and molecular phylogenetic analysis and biological and morphological comparisons place the new species close to A. halicti from Halictus ligatus and A. puri from Augochlora pura from North America, although the new species is distinguished from A. halicti and A. puri based upon its stomatal morphology of males and females, male spicule and gubernaculum morphology and female vulval structure.

Abstract Acrostichus dauer larvae (JIII) were recovered during dissections of the palmetto weevil, Rhynchophorus cruentatus, from southern Florida, and the palm weevil, R. palmarum, from Colombia, Costa Rica and Trinidad. Based upon morphological and molecular studies, the four isolates are conspecific and are described herein as A. rhynchophori n. sp. Acrostichus rhynchophori n. sp. is characterised by narrow, flap-like dorsal tooth, female gonads not reflexed to the level of the vulva, male spicule and gubernaculum morphology, i.e., spicule with small and indistinct manubrium embedded in lamina/calomus complex, strong expansion just posterior to manubrium and smoothly curved and smoothly tapered lamina/calomus complex, and gubernaculum with claw-like anterior end in lateral view and three distal branches in ventral view. The new species is distinguished from A. superbus by morphology of the spicule and gubernaculum. Type specimens of four other Acrostichus species, originally described from bark beetles from North America, i.e., A. concolor, A. gubernatus, A. ponderosus and A. taedus, were re-examined and photo-documented.

Three New Species

Three new species and one new record are added to the philopotamid fauna of India from the Indian Himalaya. The newly described species under the genus Chimarra Stephens include Chimarra butticulata sp.n. and C. gangotriensis sp.n. both from Uttarakhand and C. sangtami sp.n. from Nagaland. The record of C. nigra Kimmins (from Sikkim) constitutes the first record of that species from India, although it was previously known from Nepal. It is redescribed here from India as there are minor differences in the male genitalia from previously described species (in original paper of Kimmins only lateral view of the phallus was illustrated and in the redescribed species the ventral view of phallus is illustrated along with the lateral view). The four species belong to two different species groups and one species is unplaced in the species group. These species are distinguishable from each other as well as from the previously known allied species by consistent taxonomic features of the inferior appendages, tergite X, and the phallic apparatus of males.

We conducted an inventory of the Trichoptera fauna of Serra do Tepequém, Amajari municipality (county), Roraima state, Brazil. Adult caddisflies were collected with Pennsylvania and Malaise traps operated beside three 2nd-order streams near the summit of Serra do Tepequém. We identified 27 Trichoptera species (including two new species), all representing new records for the state of Roraima, five of these species are recorded for the first time in Brazil. In this study, two new species are described: Marilia mahedae sp. nov. differs from all other species of the genus by the following combination of characters: Segment X subquadrate in dorsal view, bipartite, membranous mesally, with short apical V-shaped incision; preanal appendages wide at base in lateral view; endotheca with an acute subapicoventral projection, directed anterad in lateral view; phallotheca very short. Polyplectropus tepequemensis sp. nov. differs from all other species of the genus by the following combination of characters: Posterior margin of sternum IX nearly straight; slightly sclerotized intermediate appendages broad in the basal 2/3 and abruptly slender apically; two phallic ducts, each with an endothecal spine. With this inventory the number of Trichoptera species for Roraima state increased from 37 to 65.
