The specimens studied were collected with sweep net and pitfall in the forests, agro-forests, herbaceous fallows, and crop fields of 14 localities in the southern part of Cameroon, from August 2015 to February 2018. The results show that Heteracris hannai sp. nov. and Heteracris lecoqi sp. nov. differ from previously known species of the same genus by the pattern of coloration and the details or shape of the phallic complex. H. lecoqi sp. nov. is characterized by light brownish body; male cercus with flattened, downcurved and obtuse apex; lophus strongly curved; interlophal space with V shape; apodeme of cingulum bow, convergent, with V-shape; valve of cingulum in lateral view longer than apical valve of penis; ramus in ventral view joined. H. hannai sp. nov. is distinct to other species by brown to grey body; male cercus with apex rounded, curved inside; lophus curved; interlophal space with U-shape; apodeme of cingulum thick, slightly parallel, with U shape; valve of cingulum in lateral view hardly longer than apical valve of penis; ramus in ventral view opened. The characteristics of H. guineensis are closer to H. hannai sp. nov. than to H. lecoqi sp. nov. H. lecoqi sp. nov. was collected only in the fallows while H. hannai sp. nov. was collected in the forests, agro-forests, fallows, and crop fields. Compared to H. guineensis, both new species are scarce in the natural vegetation and their distribution area is limited to two and four localities respectively for H. lecoqi sp. nov. and H. hannai sp. nov. All these three grasshopper’s species were recorded as accidental species in all types of vegetation.

Three New Species

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.

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.

A New Species

AbstractA new species of entomopathogenic nematode, Steinernema everestense n. sp., was recovered from soil samples collected from Pakhribas, Dhankuta district of Nepal, during a survey in 2007. The analysis of ITS-rDNA and D2D3 LSU sequences placed S. everestense n. sp. in the feltiae-kraussei-oregonense group. The nematode can be separated from other described species of Steinernema by morphological and morphometric characteristics and by characterisations and phylogeny inferred from DNA sequences of the D2D3 LSU or ITS regions of rDNA. For infective juveniles, the new species can be recognised by the body length of 775 (705-838) μm, pharynx 119 (110-130) μm long, H% = 61 (47-68) and E% = 78 (60-89). The lateral field pattern is 2, 8, 6, 4, 3. The males have well curved, brownish-yellow spicules with a prominent but short velum, gubernaculum plump, boat-shaped to almost straight in lateral view, cuneus long, needle-shaped, corpus with two wings in ventral view. Spicule and gubernaculum length of the first generation males is 79 (65-87) μm and 50 (39-57) μm, respectively. A tail mucron is present in both male generations. Genital papillae total 23 or 25, comprising 11 or 12 pairs and a single midventral papilla. Specimens with 23 genital papillae have eight precloacal pairs (seven pairs subventral and one pair lateral), two pairs subterminal and one pair subdorsal. The most posterior two pairs are consistently located near the tail tip. The specimens with 25 genital papillae have an extra adcloacal pair of papillae and the anteriormost two pairs are close together. The vulva is slightly protruding, mostly with equal lips, and low epiptygmata. A post-anal swelling is developed in most first and all second generation females.

Parapachymorpha is one of eight genera within the tribe Medaurini of subfamily Clitumninae (Phasmatidae). It was established by Brunner von Wattenwyl (1893), with the type species Parapachymorpha nigra by subsequent designation of Kirby (1904), from Myanmar. Species of this genus are widely distributed in oriental tropics (Laos, China, Thailand, Myanmar, Vietnam and Cambodia), with only 11 known species in the world (Brock et al. 2018, Ho 2017). Species of the genus Parapachymorpha can be recognized by following characters (Brunner von Wattenwyl 1893;1907, Henmemann & Conle 2008, Ho 2017): 1) body robust in female and slender in male with long leg in relation to the length; 2) body surface of female granulose or spinose; 3) mesonotum of female more and less expanded posteriorly; 4) abdominal tergites lacking expanded prostero–lateral angles in both sexes; 5) laminal supraanalis undeveloped in female; 6) semi–tergite of male irregularly rectangular, with an additional finger­–like ventro–apical appendix on the lower margin and reduced or absent; 7) egg capsule oval to oblong and covered with a raised net–like structure in lateral view; 8) micropylar plate oval; 9) operculum concave or convex. In the present study, we describe additional species, Parapachymorpha minuta sp. nov. from Laos, with photographs of both sexes of adults and egg.
