A New Species

A new species of Tricorythopsis is described, illustrated and diagnosed based on nymphs from Pará state, Brazil. Tricorythopsis similis sp. nov. is related to Tricorythopsis rondoniensis (Dias, Cruz & Ferreira) based on abdominal terga III–VII with acute tubercles medially located on posterior margins, and by the absence of the transversal line on operculate gill. However, the new species can be identified by the following combination of characteristics: general coloration yellowish brown, with blackish and purplish marks irregularly distributed; maxillary palp 1-segmented; segment II of labial palp shorter than segment I and longer than segment III; femora and tibiae with margins covered by long, pectinate setae; tarsal claws with 4 to 5 marginal denticles and 4+2 very small, submarginal denticles. This is the first species of Tricorythopsis recorded from Pará state.

Abstract The efficacy of tree injected with emamectin benzoate (EB) against the Asian long-horned beetle (ALB) was tested in a heavily infested willow forest in Beijing, China. In a 1.7-ha plot, 240 out of 310 trees were treated with two EB formulations at various rates. After fall application, the larval population decreased by 89% in the following spring and by >99% during the second year detected by monitoring new frass emission from marked holes. Consequently, the number of exit holes of emerging adults decreased to 0 in the second year. Re-infestation occurred in the third year after application. This high efficacy and lasting activity might be contributed to: a) a favorable translocation of EB in trees when injected into the sapwood; b) the high intrinsic activity against ALB larvae with LC50 of 20–30 ppb; and c) a reduced lifespan of ALB adults by over 60% when feeding on twigs of EB-treated trees. On untreated control trees, the larval population decreased during the first winter. In the second year after application, the larval population was wiped out during winter and a re-infestation started from border trees by adults flying in from outside the trial plot. This pattern indicates an eradication of the ALB population in the 1.7-ha plot can be expected 2 yr after EB treatment. The benefit of treating with EB on the surrounding population was observed in both the untreated trees and imidacloprid-treated trees, suggesting that treatment of EB benefits both the treated trees and the surrounding trees in the area.

The structure and innervation as determined by methylene blue techniques of the sensilla of the maxillary palp, galea, mandible, labrum, and labial palp of the spruce budworm larva are described, based on light and scanning electron microscopy. An attempt is made to identify the function of various sensilla by comparing them with those of other insects. The function of the gustatory sensilla on the galea and epipharynx is confirmed electrophysiologically.

Morphological Differences

The egg of Paederidus ruficollis (Fabricius, 1781) and larvae of that and P. rubrothoracicus carpathicola Scheerpeltz, 1957 are described and illustrated. This is the first thorough description of immature stages for the genus Paederidus Mulsant & Rey (1878). The immature stages were obtained by rearing adults. Morphological differences between instars of the same species and also between the studied species are found in the detailed structure of the antenna, nasale, maxillary palp, labial palp, tarsungulus and urogomphus; chaetotaxy of pronotum, profemur and protibia; proportions of same body parts; microstructure of urogomphus and body colour. Comparative characters of larvae of two subtribes Paederina and Stilicina are presented.

One New Species

The fauna of bristletails of the family Machilidae in Kazakhstan currently includes one species of the genus Silvestrichiloides Mendes, 1990 and 13 species of the genus Allopsontus Silvestri, 1911. The present study describes one new species of the genus Silvestrichiloides (S. berkarensis Kaplin, sp. nov. from South Kazakhstan) and two new species of the genus Allopsontus (A. (Kaplinilis) nigrostriatus Kaplin, sp. nov. and A. (Machilanus) perfectus Kaplin, sp. nov. from Southeastern Kazakhstan). Silvestrichiloides berkarensis sp. nov. differs from the other species of this genus in the structure of antennal flagellum, apical palpomere of labial palp and ovipositor. Among species of the subgenus Kaplinilis Mendes, 1990, A. nigrostriatus sp. nov. belongs to a group of species characterized by numerous short chaetae on the ventral surface of the 5–7th palpomeres of the male maxillary palp and by the absence on the labial palp. This group includes two species: A. volgensis Kaplin, 1999 from Samara Region and A. smelyanskii Kaplin, 1999 from Orenbourg Region (both Russia). The new species differs from A. volgensis and A. smelyanskii in the length of the body and antenna, color of scales on the upper surface of the body, shape of the compound eye and paired ocellus, structure of the flagellum and apical palpomere of the male labial palp. The subgenus Machilanus Silvestri, 1934 is represented only by A. bitschi Wygodzinsky, 1962 from Afghanistan and A. perfectus sp. nov., which are characterized by numerous short chaetae on the ventral surface of the 2nd–7th palpomeres of the male maxillary palp. Allopsontus perfectus sp. nov. differs from A. bitschi in the shape of compound eyes, paired ocellus, structure of male labial palp and genitalia.

Generic Description

AbstractA revised generic description of the three larval instars of Omophron is presented. Hypothetical apotypic character states of the genus are: bidentate retinaculum; lacinia subequal in length to galea and apically subspatulate; ligula as long as labial palp; pore LAa located on ligula and seta LA6 on basal third of ligula; setae TI2* and TI7* of middle and hind tibiae located basally; setae UN1 and UN2 flat and about 1.5 times the length of claws; presence of serially paired gland-like structures on abdominal pleura I–VII; hypopleurites not apparent in first instar; apex of urogomphi extended as a small hyaline appendix in first instar; setae PY1, PY2, and PY6 on the pygidium absent. Most of these character states are autapotypic, and no synapotypies were found to indicate a sister group to Omophron.
