“…Considering these evolutionary trends, S. agassizii, with an open thelycum and a complex spermatophore, can be considered as a less derived species within the Dendrobranchiata. This coincides with the general assumption that within solenocerids, the genus Solenocera approaches some morphological aspects of penaeids (Burkenroad 1983, Tavares & Martin 2010. …”

“…There are many suggested functions, mostly associated with the process of copulation (King 1948, Boschi & Angelescu 1962, Bauer 1994, Tavares & Martin 2010. Bauer (1996) mentioned that in Sicyonia dorsalis the petasma may temporarily connect male and female genitalia during copulation and/or adjust the position of the male genital papilla relative to the aperture of a spermatheca.…”

“…The wings have been described to be securely anchored to a groove on the sternal surface between the third and fourth pereopods of L. setiferus (King 1948, Pérez-Farfante 1975, Pérez-Farfante & Boris 1982, Chow et al 1991, which coincides with our observations for S. agassizii. The glutinous mass is composed of adhesive and glutinous secretions (Pérez-Farfante 1975, Talbot & Beach 1989, Bauer & Cash 1991, Tavares & Martin 2010 Quadrangular area with a median bald prominence in front of the two spine-covered prominences between the 5th legs; 2 small spiny papillae in front of the quadrangular area.…”

Solenocera agassizii is commercially exploited along the Costa Rican Pacific coast and represents around 30% of the country's total shrimp catch. Despite its economic importance, information on its biology is scarce. Here we describe its secondary sexual characters and spermatophores. The open thelycum is located between Sternites XIII and XIV. A pair of parallel setose projections (Sternite XIV) is distally curved in larger females (< 30 mm carapace length); a disk-shaped projection (Sternite XIII) emerges from Pereopod IV and projects towards Sternite XIV, and a triangular emargination is present (Sternite XIII). The semi-open petasma with cincinnulli connecting the pleopods in mature males has sclerotized dorsolateral (DL), ventrolateral (VL) and ventromedian (VM) lobules. The VM tooth-like projections fit the VL tooth-like projections. The DL and VL lobules end in a leaf-like, less sclerotized projection and are separated by a gap. The VL lobule has a patch of spinules and a highly sclerotized costa. An elongated appendix masculina (AM) with concave margin forms a distal subtriangular lobe and has a DL margin with an aggregation of setae. The AM fits inside the appendix interna (AI) and is shorter and narrower than the AM. The spermatophore has superior (wing) and inferior (germinate body) sections. The GB ends in a triangular hook-like structure. The thelycum resembles that of S. geijskesi, whereas the petasma, AM and AI are similar to those of Atlantic solenocerids. The complex spermatophore resembles that of other penaeoid shrimp. According to evolutionary trends, S. agassizii can be considered as a less derived species within the Dendrobranchiata.

“…The great majority of dendrobranchiate shrimps, at least in some part of their life cycle, live in marine and/or estuarine waters, with only a few exceptions of sergestids which are exclusively found in freshwater (Pérez Farfante andKensley 1997, Tavares andMartin 2010). This environmental condition is the same described for the area where A. timidus n. gen. n. sp.…”

“…Differently from the Caridea, in which the pleura of the second abdominal somite overlap the first and the third, in Penaeoidea the pleuras of the anterior somites always overlap the posterior somites (Glaessner 1969, Feldmann andSchweitzer 2010). According to several authors, this character is one of the diagnostic characters for Dendrobranchiata (Burkenroad 1981, Pérez Farfante and Kensley 1997, Dixon et al 2003, Tavares and Martin 2010. We believe this new species belongs to the superfamily Penaeoidea due to the proportion of the sixth abdominal somite, which is considerably more elongated in several sergestid species, including Paleomattea deliciosa, described from the same formation (Maisey and Carvalho 1995).…”

The fossil shrimp Araripenaeus timidus n. gen. n. sp. is the first fossil Penaeoidea from Brazil. Here, we describe, illustrate and compare it with Paleomattea deliciosa, a fossil Sergestoidea (Dendrobranchiata) previously described from the same region. The material of the early Cretaceous (Albian) was collected in the town of Jardim, south of the state of Ceará, in the superior septarian concretion level of the Romualdo Formation. Additionally, a second specimen of Kellnerius jamacaruensis was found in the same site of the Araripe Basin.

Mid-water plankton collections commonly include bizarre and mysterious developmental stages that differ conspicuously from their adult counterparts in morphology and habitat. Unaware of the existence of planktonic larval stages, early zoologists often misidentified these unique morphologies as independent adult lineages. Many such mistakes have since been corrected by collecting larvae, raising them in the lab, and identifying the adult forms. However, challenges arise when the larva is remarkably rare in nature and relatively inaccessible due to its changing habitats over the course of ontogeny. The mid-water marine species Cerataspis monstrosa (Gray 1828) is an armored crustacean larva whose adult identity has remained a mystery for over 180 years. Our phylogenetic analyses, based in part on recent collections from the Gulf of Mexico, provide definitive evidence that the rare, yet broadly distributed larva, C. monstrosa, is an early developmental stage of the globally distributed deepwater aristeid shrimp, Plesiopenaeus armatus. Divergence estimates and phylogenetic relationships across five genes confirm the larva and adult are the same species. Our work demonstrates the diagnostic power of molecular systematics in instances where larval rearing seldom succeeds and morphology and habitat are not indicative of identity. Larval–adult linkages not only aid in our understanding of biodiversity, they provide insights into the life history, distribution, and ecology of an organism.
