Abstract. Although the generic name implies that the genus Malayaxenos Kifune is from Southeast Asia, the current distribution is more cosmopolitan. Species are now known from Germany, United States of America, Dominica, Colombia, Australia, and Malaysia. As part of this distribution, four new species are named: Malayaxenos baileyi new species, Malayaxenos dominicensis new species, Malayaxenos kogani new species, and Malayaxenos platycephala new species. Additionally, Australoxenos Kathirithamby is proposed here as a junior synonym of Malayaxenos, making its only species Malayaxenos yetmaniensis new combination. All species in Malayaxenos are herein described or reviewed and a world key is provided for species identification.

Abstract. A new cryptic oxycarenid seed bug, Crophius arribus new species (Hemiptera: Heteroptera: Oxycarenidae), is described from the Mexican states of Chiapas, México, Puebla, and Querétaro, and Arizona, USA. The new species is assigned to the genus Crophius Stål even though the length of the labium and the number of fore femoral spines exceed the established generic limits. A lectotype is designated for Oxycarenus scabrous (Uhler).

Abstract. The genitalia of an unusually pale and uniform male of Gesta (Erynnides) from central Texas are intermediate between those of Gesta horatius and Gesta tristis tatius, owing to interspecific hybridization. These sister species are widely distributed (mainly from the eastern United States and from the southwestern United States to Colombia, respectively) and barely sympatric. Four different methods of analyzing data from whole genome sequencing of 7 specimens of each parental species, 6 specimens of related species G. meridianus (as an outgroup), and the specimen with the peculiar genitalia show that it is an F1 hybrid whose mother is G. t. tatius. The superficial appearance of this hybrid does not suggest either parent.

the most species-rich genus of Symphyta (sawflies) with more than 1000 described species worldwide—roughly 154 of these found in the Nearctic Region (Taeger et al. 2018, Goulet 2020). Despite their larger body size relative to many sawflies, surprisingly little is known of the biology of this genus in North America—we estimate the life histories of greater than 90 percent remain unknown (Baine et al. 2019). Published host records are documented from a wide diversity of plant families, and while several species appear to be highly specialized, many Palearctic Tenthredo are considered to be mainly polyphagous (Goulet 1996). Herein, we reveal for the first time the life history of T. mellicoxa Provancher, 1878 (Fig. 2) from Virginia waterleaf (Hydrophyllum virginianum L.) (Boraginaceae). As the first member of the T. rufopectus species group with a known life history, we hope this discovery will offer clues to the biology of related Tenthredo species, i.e., T. rufopectus (Norton, 1860), T. nimbipennis Cresson, 1872, T. ruma MacGillivray, 1923, and T. fernowi Goulet and Smith, 1995. As T. mellicoxa appears to be a Hydrophyllum specialist, we predict its kin may also be dietary specialists. In late April 2022, in Brown Co., Kansas (Hamlin, No-man’s Land Farm, (39.90625° lat, -95.58656° long)), TAM observed an abundance of adult T. mellicoxa flying around a large stand of Virginia waterleaf in a mesic, mixed deciduous forest (Fig. 1). Where the adults were abundant, Hydrophyllum, just shy of blooming, stood about 0.5 m tall and was the dominant understory plant. Adult Tenthredo (Fig. 2) were readily collected with a sweep net as they skimmed low above the waterleaf or as they perched on the upper surface of waterleaf leaves. TAM netted four adult females and placed them into separate 50-dram vials, each bearing a single Hydrophyllum leaf. All four females successfully oviposited. Observed details of the life history are as follows. Ova were inserted between the lower epidermis and mesophyll in nonvascular areas of the waterleaf leaf tissue (Fig. 3). The captive oviposition rate was remarkably consistent across the four captured females; each laid 12–15 eggs, with oviposition slowing 48 hours post collection and ceasing altogether 72 hours post collection. Eggs hatched 9–10 days post oviposition and first instar larvae immediately began feeding solitarily within the interior of the leaf blade leaving ovate holes behind (Fig. 4). The cloudy white bloom of early instars was replaced by the characteristic gray dorsum of later instars in the third instar. Like other Tenthredo and related genera, when not actively feeding larvae often coiled themselves on the undersides of the leaves, and when disturbed, would drop from the leaf surface. The fifth, prepupal instar did not form a silken cocoon, but rather was found to shelter in an earthen cell, presumably overwintering until pupation and subsequent eclosion the following spring. The average time from oviposi

Abstract. No comprehensive identification resource is available for the genus Frankliniella. In response, a dynamic internet–based platform with interactive identification tools, species fact sheets and slide preparation tutorials are being developed by the author(s). We reviewed certain type, port interceptions, and origin collected specimens. We attempted to validate species identification using non-destructive DNA extraction and sequencing of both intercepted and field collected specimens. Sequences explicitly linked to a permanently curated morphological voucher specimen were deposited in a public repository (GenBank). The morphological review and genetic analysis revealed that both F. bruneri Watson and F. xanthaner Hood are each likely cryptic species complexes. Five species are described, F. ecuatoriana new species, F. funderburki new species, F. pelucensis new species, F. sanabriana new species and F. suramericana new species. Sequence data are recorded for the holotype specimens of the latter four species. Taxonomic status changes for F. genuina Hood and F. venusta Moulton are provided.

Abstract. During collections made in 2019 and 2020 at different localities in the Sierra Norte de Puebla (Northern Sierra of Puebla), Mexico, some odonate specimens, representing new state records of three genera and 16 species, were captured. Among the new records there are little known species such as Erpetogomphus erici (Novelo and Garrison, 1999), E. liopeltis (Garrison, 1994) and Phyllocycla breviphylla (Belle, 1975). Furthermore, new localities are recorded for uncommon species, such as Paraphlebia zoe (Selys in Hagen, 1861), Argia percellulata (Calvert, 1902) and Erpetogomphus viperinus (Selys, 1868). These records add to the already known species richness of the state of Puebla, increasing it from 110 to 126 species. As a result, the state of Puebla is now in tenth place nationally in terms of species richness.

Abstract. Diaphorina citri is considered the most serious pest of citrus. It transmits the bacterium Candidatus Liberibacter spp., which causes Huanglongbing disease. Augmentation biological control of D. citri involves the release of the parasitoid Tamarixia radiata and entomopathogenic fungi. The following potential predators were evaluated in the present study: Ceraeochrysa valida, Ceraeochrysa sp. nr. cincta, Chrysoperla externa and Chrysoperla rufilabris. The evaluated parameters included maximum predation rate, functional response, handling time and search time. C. externa showed the highest predation rate (274.1 ± 3.1a). The correlation coefficient for the four species was higher than R2 = 0.95, while the linear coefficient P1 was negative and significant, indicating a type II functional response. The third instar of C. externa showed high search capacity (1.7905 ± 0.0737), while the first instar of C. valida was associated with low search capacity (0.6243 ± 0.1118). The highest and lowest values of handling time were recorded in the third (0.00891 ± 0.00105) and second instars (0.00931 ± 0.000075) of C. valida. The species C. rufilabris showed the highest search capacity value (1.3551 ± 0.0261) and the lowest handling time (0.00899 ± 0.00008904). The results show that the predatory capacity of the four species is a function of their stage of development and the density of the prey. The species C. externa and C. rufilabris showed to be the most suitable natural enemies for population regulation of D. citri. Resumen. Diaphorina citri se considera la plaga más grave de los cítricos. Transmite la bacteria Candidatus Liberibacter spp., causante de la enfermedad Huanglongbing.

En el presente estudio se evalúan las siguientes alternativas de control mediante los depredadores Ceraeochrysa valida, Ceraeochrysa sp. nr. cincta, Chrysoperla externa y Chrysoperla rufilabris. Los parámetros evaluados incluyen la tasa máxima de depredación, la respuesta funcional, el tiempo de manipulación y el tiempo de búsqueda. C. externa mostró la mayor tasa de depredación (274,1 ± 3,1a). El coeficiente de correlación para las cuatro especies fue superior a R2 = 0,95, mientras que el coeficiente lineal P1 fue negativo y significativo, indicando una respuesta funcional de tipo II.

Diaphorina citri is considered the most serious pest of citrus. It transmits the bacterium Candidatus Liberibacter spp., which causes Huanglongbing disease. Augmentation biological control of D. citri involves the release of the parasitoid Tamarixia radiata and entomopathogenic fungi. The following potential predators were evaluated in the present study: Ceraeochrysa valida, Ceraeochrysa sp. nr. cincta, Chrysoperla externa and Chrysoperla rufilabris. The evaluated parameters included maximum predation rate, functional response, handling time and search time. C. externa showed the highest predation rate (274.1 ± 3.1a). The correlation coefficient for the four species was higher than R2 = 0.95, while the linear coefficient P1 was negative and significant, indicating a type II functional response. The third instar of C. externa showed high search capacity (1.7905 ± 0.0737), while the first instar of C. valida was associated with low search capacity (0.6243 ± 0.1118). The highest and lowest values of handling time were recorded in the third (0.00891 ± 0.00105) and second instars (0.00931 ± 0.000075) of C. valida. The species C. rufilabris showed the highest search capacity value (1.3551 ± 0.0261) and the lowest handling time (0.00899 ± 0.00008904). The results show that the predatory capacity of the four species is a function of their stage of development and the density of the prey. The species C. externa and C. rufilabris showed to be the most suitable natural enemies for population regulation of D. citri. Resumen.
