Revision of Neotropical wolf spider genus Arctosa C.L. Koch, 1847 (Araneae: Lycosidae), with description of seven new species.

The genus Arctosa C.L. Koch is redescribed and diagnosed. Seven new species are described, four of them based on both sexes (A. conflicta sp. nov., A. costenola sp. nov., A. jibarosa sp. nov. and A. villa sp. nov.), two only on females (A. ayaymama sp. nov. and A. mineira sp. nov.), and one only on the male (A. pacaya sp. nov.). We also propose the transference of Arctosa humicola (Bertkau, 1880) and Arctosa fusca (Keyserling, 1877) to Trochosa C.L. Koch, 1847, and the new synonymy of Arctosa inconspicua (Bryant, 1948) with Trochosa humicola (Bertkau, 1880) comb. nov. Besides, Arctosa andina (Chamberlin, 1916) and Arctosa pugil (Bertkau, 1880) are transferred to Hogna Simon, 1885, and Arctosa aussereri (Keyserling, 1877) to Prolycosides Mello-Leito, 1942. Additionally, eight lycosid species are synonymized with Prolycosides aussereri: Schizocosa proletaria (Tullgren, 1905); Arctosa workmani (Strand, 1909); Hogna planithoracis (Mello-Leito, 1938); Hogna variolosa (Mello-Leito, 1941); Megarctosa melanostoma (Mello-Leito, 1941); Hippasosa huachoi (Mello-Leito, 1942); Pirata abalosi (Mello-Leito, 1942); and Pirata soukupi (Mello-Leito, 1942). We also transfer Trochosa tenebrosa Keyserling, 1877 to Arctosa. The males of Arctosa tenebrosa (Keyserling, 1877) comb. nov. and Trochosa humicola (Bertkau, 1880) comb. nov. are described for the first time.

Taxonomic revision of the jumping spider genus Tullgrenella Mello-Leito, 1941 (Araneae: Salticidae: Freyina).

This paper presents a taxonomic revision of the genus Tullgrenella Mello-Leito, 1941. Four new species are described: Tullgrenella aisenbergae Marta, sp. nov. (Brazil) (), T. legalissima Marta & Hagopin sp. nov. (Uruguay) (), T. galianoae Marta, sp. nov. (Brazil) () and T. sciosciae Marta & Bustamante sp. nov. (Brazil) (). The males of T. corrugata Galiano, 1981 and T. peniaflorensis Galiano, 1970, and the female of T. selenita Galiano, 1970 are described for the first time. An updated diagnosis for the genus is provided based on the detailed comparative morphological studies. In addition, we present a proposal and discussion about the species groups of Tullgrenella based on the putative synapomorphies as well as the updated distribution of the genus in South America.

Tidying things up: Tropicosa, a new Neotropical wolf spider genus (Araneae: Lycosidae: Lycosinae).

The new genus Tropicosa is proposed based on species of some controversial Neotropical genera of lycosids. These spiders present a longitudinal dark stripe over the sternum in both sexes, median apophysis sinuous, tegular lobe evidently sclerotized and the epigyne with median septum anteriorly expanded and with a parallel, triangular hood. We transfer Alopecosa moesta (Holmberg), Schizocosa chelifasciata (Mello-Leitão) and Lycosa thorelli (Keyserling) to Tropicosa gen. nov. and describe one new species, Tropicosa baguala sp. nov. Likewise, Arctosa bogotensis (Keyserling) is synonymized with Tropicosa thorelli (Keyserling) comb. nov., and Lycosa langei Mello-Leitão with T. chelifasciata (Mello-Leitão) comb. nov. based on examined types. All the four species proposed as members of Tropicosa gen. nov. have South American distribution.

Implementation of the 7-1-7 target for detection, notification, and response to public health threats in five countries: a retrospective, observational study.

BACKGROUND: Suboptimal detection and response to recent outbreaks, including COVID-19 and mpox (formerly known as monkeypox), have shown that the world is insufficiently prepared for public health threats. Routine monitoring of detection and response performance of health emergency systems through timeliness metrics has been proposed to evaluate and improve outbreak preparedness and contain health threats early. We implemented 7-1-7 to measure the timeliness of detection (target of ≤7 days from emergence), notification (target of ≤1 day from detection), and completion of seven early response actions (target of ≤7 days from notification), and we identified bottlenecks to and enablers of system performance. METHODS: In this retrospective, observational study, we conducted reviews of public health events in Brazil, Ethiopia, Liberia, Nigeria, and Uganda with staff from ministries of health and national public health institutes. For selected public health events occurring from Jan 1, 2018, to Dec 31, 2022, we calculated timeliness intervals for detection, notification, and early response actions, and synthesised identified bottlenecks and enablers. We mapped bottlenecks and enablers to Joint External Evaluation (second edition) indicators. FINDINGS: Of 41 public health events assessed, 22 (54%) met a target of 7 days to detect (median 6 days [range 0-157]), 29 (71%) met a target of 1 day to notify (0 days [0-24]), and 20 (49%) met a target of 7 days to complete all early response actions (8 days [0-72]). 11 (27%) events met the complete 7-1-7 target, with variation among event types. 25 (61%) of 41 bottlenecks to and 27 (51%) of 53 enablers of detection were at the health facility level, with delays to notification (14 [44%] of 32 bottlenecks) and response (22 [39%] of 56 bottlenecks) most often at an intermediate public health (ie, municipal, district, county, state, or province) level. Rapid resource mobilisation for responses (six [9%] of 65 enablers) from the national level enabled faster responses. INTERPRETATION: The 7-1-7 target is feasible to measure and to achieve, and assessment with this framework can identify areas for performance improvement and help prioritise national planning. Increased investments must be made at the health facility and intermediate public health levels for improved systems to detect, notify, and rapidly respond to emerging public health threats.

A new huriine genus and notes on morphological characters (Araneae: Salticidae: Salticinae).

Huriini Simon, 1901 currently consists of six genera and 17 species, distributed exclusively in South America. In this work, the huriine genus Guriurius Marta, Bustamante, Ruiz Rodrigues, gen. nov. is proposed with two new species herein described: Guriurius minuano Marta, Bustamante, Ruiz Rodrigues, sp. nov. (type species) and Guriurius nancyae Marta, Bustamante, Ruiz Rodrigues, sp. nov. The female of Atelurius segmentatus Simon, 1901 is described and illustrated for the first time. Scoturius dipterioides Perger Rubio, 2018 is transferred to Atelurius Simon, 1901 due to the morphological similarity of copulatory ducts of epigyne, and Hurius pisac Galiano, 1985 is transferred to Simonurius Galiano, 1988 due to the similarities in body shape and female genitalia. Simonurius campestratus (Simon, 1901) is synonymized with Simonurius quadratarius (Simon, 1901). The interpretation of genitalic characters in Huriini is discussed. In addition, we provide new distributional records for Admesturius bitaeniatus (Simon, 1901), Ad. mariaeugeniae Bustamante Scioscia, 2014, Ad. schajovskoyi Galiano, 1988, At. segmentatus Simon, 1901, Scoturius tigris Simon, 1901, Hurius aeneus (Mello-Leito, 1941), and Simonurius gladifer (Simon, 1901). Except for Urupuyu Ruiz Maddison, 2015, all huriine genera are rediagnosed in the new context of tribe and genus composition.

Três padrões novos de coloração de ninfas de Arvelius albopunctatus (De Geer) (Hemiptera: Pentatomidae) / Three new color patterns of nymphs of Arvelius albopunctatus (De Geer) (Hemiptera: Pentatomidae)

Arvelius albopunctatus (De Geer) é amplamente distribuída na região Neotropical, sendo uma importante praga de Solanaceae. Foram descritas variações na coloração das ninfas para essa e outras espécies de pentatomídeos e seu conhecimento é essencial para a identificação precoce. Foram coletadas ninfas e adultos de A. albopunctatus em fragmentos florestais em Criciúma, Içara, Maracajá e Araranguá, SC, de dezembro de 2005 a julho de 2006. Foram observadas as formas de coloração conhecidas das ninfas de 4º e 5º ínstares, bem como três tipos novos, aqui descritos e denominados forma vermelha (4º e 5º ínstares), forma verde (4º e 5º ínstares) e forma laranja (5º ínstar).

Arvelius albopunctatus (De Geer) is widely distributed in the Neotropical region, being an important pest of Solanaceae. Color variation of nymphs was described for this and other pentatomid species and their knowledge is essential for an early identification. From December 2005 to July 2006 nymphs and adults of A. albopunctatus were collected in forest fragments in Criciúma, Içara, Maracajá and Araranguá (SC, Brazil). Known morphs of nymphs of both 4th and 5th instars were observed, as well as three new morphs, here described and named red morph (4th and 5th instars), green morph (4th and 5th instars) and orange morph (5th instar).
