Natural history
All observed Ancylometes species (bogotensis, hewitsoni, riparius, rufus, terrenus) are nocturnal hunters and strongly ground related, however they climb on tree trunks to hide during inundation of the ground or to flee from army ants. During the day they hide in crevices and at night they hunt in a sit-and-wait manner, often near water bodies. The biology of A. rufus in a terra firme forest near Manaus (Reserva Ducke) was studied by Azevedo (1999). The species is most frequently observed along small rivers in the forest. An observed strong temporal variation of densities along the stream indicated seasonal migrations within the habitat, e.g. to the stream banks during the dry season and to small water ponds within the forest during the wet season.
Hunting on frogs has repeatedly been observed for several species (Brandão pers. comm. for A. concolor - IBSP 6536, preying Hyla sp.; for A. rufus and A. hewitsoni pers. obs. and photo in Höfer & Beck 1996, photos in Bernarde et al. 1999, Hödl 1993); and tadpoles (pers. obs.) and fish (pers. obs.) are also preyed. The spiders can easily paddle on the water surface, and dive for prey but also to hide; remaining more than 30 minutes below water has been recorded (pers. obs.). One bite accident in Manaus has been brought to our knowledge, but in the field these spiders are not at all aggressive and can easily be captured by hand. Moults are often found hanging down from leaves in vegetation (30-50 cm above ground). One male which was kept for one night in a small device had difficulties to moult, which resulted in curved legs. Pompilid wasps have been observed to prey on Ancylometes spiders. To avoid flooding in inundation forests and army ant raids in terra firme forest the spiders climb on tree trunks, where they were caught in arboreal funnel traps.
Mating of A. bogotensis was described by Merrett (1988). We found some females with their epigynes plugged. Females carry their egg sacs, which are covered by strong brown water proof silk, attached to the chelicerae and held by the pedipalps under the venter. Egg sacs of A. rufus contained more than 1000 eggs. The nursery webs constructed by the females of A. rufus are about 10 cm in diameter and were frequently encountered near the ground along the stream. Juveniles were observed to remain for about one week in the webs. Adults were encountered throughout the year indicating that there is no seasonal reproduction(Azevedo 1999).

Symphysanodon

description: [[Genus Symphysanodon Bleeker]]
The small to medium-sized perciform fishes of the genus Symphysanodon Bleeker inhabit waters over the continental shelf, upper continental slope, and submarine ridges and occur in similar depths in insular areas. The genus is known from 10 species -six previously described (S. andersoni Kotthaus, S. berryi Anderson, S. katayamai Anderson, S. maunaloae Anderson, S. octoactinus Anderson, and S. typus Bleeker), the three described herein, and a species known only from stomach contents of a specimen of Latimeria chalumnae Smith collected off the Comoros in the western Indian Ocean. Symphysanodon has been treated variously as a member of the Acropomatidae, Serranidae, or Lutjanidae, but it lacks traits that would support assigning it to any of those families. Fourmanoir (1981), without explanation, erected the monotypic family Symphysanodontidae, an action that seems justified because Symphysanodon does not appear to possess characters that would allow its placement elsewhere. During an extensive study of the branchial morphology of bony fishes, the second author examined a specimen of Symphysanodon, collected in Mona Passage off the west coast of Puerto Rico, that differs from all other species of Symphysanodon in number of gillrakers on the first arch. It also differs from the other two Atlantic species and at least five of the other species of the genus in two other aspects of gill-arch structure. (Springer and Johnson, 2004, described and illustrated the dorsal gill-arch musculature of S. berryi.) The first author received from N. V. Parin material of the second new species, collected over the Sala y Gómez Ridge in the eastern South Pacific, and from the Natural History Museum in London specimens of the third new one, caught off the Maldive Islands in the northern Indian Ocean. The second new species is apparently most closely related to S. maunaloae from which it can be distinguished by mean numbers of pectoral-fin rays and tubed lateral-line scales and by several morphometric characters; the third new species is very similar to S. berryi but displays a number of morphometric differences.

Symphysanodon octoactinus

description: Symphysanodon octoactinus Anderson, 1970.
This species was referred to as Symphysanodon sp. B by Anderson (1967). Symphysanodon octoactinus, described originally from 19 specimens (58-108 mm SL), collected in the western Atlantic off the Bahamas, Puerto Rico, Nicaragua, and Panama in 156-293 m, was caught on one occasion with S. berryi off Grand Bahama Island (Anderson, 1970). We have examined five additional specimens (60-115 mm SL), collected in 183-640 (585-640) m; they are from Caribbean coast of Mexico, off Quintana Roo (UF 232079; 68 mm SL); off Belize (FMNH 70762; 2: 98-115 mm SL); off Caribbean coast of Nicaragua (FMNH 70763; 2: 60-66 mm SL). Claro et al. (2000) reported this species from off the southern coast of Cuba, based on observations and collections of specimens from the submersible Johnson Sea Link II in December 1997, and Claro et al. (2001) noted its presence off southern Cuba. Locality data for S. octoactinus are plotted in Figure 4.

Symphysanodon andersoni

description: Symphysanodon andersoni Kotthaus, 1974.
This species was described from a single specimen (ZMH 5170, 157 mm SL), collected in the western Indian Ocean southwest of Socotra Island near the entrance to the Gulf of Aden in a depth of 290-190 m (Kotthaus, 1974), and has been reported from the Gulf of Kutch, an inlet in the northeastern quadrant of the Arabian Sea on the west coast of India (Manilo and Bogorodsky, 2003) (see Figure 9). Three small specimens (USNM 326398, 40-47 mm SL) of Symphysanodon, collected by prawn trawl in 78 m off Somalia in the Gulf of Aden, may be representatives of S. andersoni (see Figure 9). Unfortunately, none of the small specimens is in good enough condition to accurately determine the most critical character (number of lateral-line scales) needed for identification as that species. Nevertheless, the presence of parapophyses on the first caudal vertebra in the holotype of S. andersoni and in the three small individuals suggests that the four specimens are conspecific (see below).

description: Symphysanodon sp. from the Comoros.
McCosker (1979) reported two partially digested specimens (7-8 cm) of Symphysanodon removed from a male coelacanth, Latimeria chalumnae (CAS 33111, 118 cm), collected in the western Indian Ocean off Grande Comore Island in ca. 225 m (pers. comm., David Catania, 14 November 2002; see Figure 9). G. David Johnson, who identified the specimens, informed McCosker that they probably represent an undescribed species (McCosker, 1979). The gillrakers on the more intact specimen of Symphysanodon number 8 + 20 (Johnson, pers. comm., 28 October 2002). A total count of 28 gillrakers on the first arch is appreciably lower than that from the only other described specimen of Symphysanodon from the western Indian Ocean, the holotype of S. andersoni, which has a total count of 41-right, 42-left (Kotthaus, 1974). Johnson appears to be correct in his appraisal of the status of the specimen on which he made a gillraker count.

Mangus

description: Genus Mangus Kopylov, gen. nov.
Etymology. The generic name refers to Mangus—Mongolian mythological beast. Gender masculine.
Type species. M. magnus sp. nov.
Species included. Type species only.
Distribution. Lower Cretaceous of Mongolia.
Diagnosis. Sc with two branches: Sc1 joining C and Sc2 joining R; Sc extending beyond Sc1 as distinctive spectral vein; pterostigma desclerotized only in the apical half; C beyond 6-Rs junction developed; 1-Rs not much longer than 1-M; 2-Rs longer than 1r-rs; Rs+M 0.8 × as long as 2-M and shorter than 1-Cu; 5-M more than 0.5 × as long as 3r-m; 2m-cu relined; 3-A1 3 × as long as 2-A1.
Comparison. The new genus differs from Kempendaja in presence of Sc2 and C beyond 6-Rs, pterostigma more sclerotized, shorter 1-Rs, longer Rs+M, 2-Rs, 5-M, 3-A1, large size.
Remarks. The diagnosis of subfamily Kempendajinae provided by A.P. Rasnitsyn (1980) appeals generally to the characters of body and hind wing morphology. Anyway by the presence of spectral Sc ending beyond Sc1, partly desclerotized pterostigma, Rs+M shorter than 1-Cu the new genus fits into Kempendajinae better than to any other anaxyelid subfamily.

Dolichosyntexis

description: Genus Dolichosyntexis Kopylov, gen. nov.
Etymology. The name is derived from generic names Dolichostigma Rasnitsyn, 1968 and Syntexis. Gender masculine.
Type species. D. transbaikalicus sp. nov.
Species included. Type species only.
Distribution. Lower Cretaceous of Transbaikalia.
Diagnosis. Fore wing with costal area narrow; pterostigma very long and broad, reaching the middle of 3r cell; both 1r-rs and 2r-rs present, 1r-rs slightly longer than 2r-rs; cell 2r small, as wide as pterostigma; cell 3r very long; Rs+M furcating before 1m-cu, 2Rs+M absent, cell 1mcu hexagonal.
Comparison. Dolichosyntexis differs from all other syntexines in having very long and broad pterostigma reaching the middle 3r cell, and small 2r cell. It also differs from Eosyntexis and Cretosyntexis in presence of two r-rs veins; from Syntexis and Parasyntexis in Rs+M furcation before 1m-cu.
Remarks. By the huge pterostigma Dolichosyntexis is close to another anaxyelid subfamily—Dolichostigma-tinae. But it differs in having long Rs+M and cell 2r very short. Basing on these characters I assign the new genus to Syntexinae and not to Dolichostigmatinae.

Curiosyntexis

description: Genus Curiosyntexis Kopylov, gen. nov.
Etymology. The name is derived from Latin curiosus—curious and generic name Syntexis. Gender masculine.
Type species. C. magadanicus sp. nov.
Species included. Type species only.
Distribution. Upper Cretaceous of Magadan.
Diagnosis. Fore wing with costal area almost absent; pterostigma short and broad, widely unsclerotized; both 1r-rs and 2r-rs present, 1r-rs incomplete and not reaching R1, potentially longer than 2r-rs; cell 1mcu pentagonal, Rs+M furcating at the level of 1m-cu; veins 3r-m and 2m-cu strongly displaced basad; tubular veins not developed beyond line connecting apices of pterostigma and 1A. Ovipositor short, scarcely protruding beyond abdominal tip.
Comparison. Curiosyntexis differs from all other genera of Syntexinae in having 3r-m and 2m-cu strongly displaced basad and in absence of tubular veins beyond pterostigma. Partly developed 1r-rs is rare within Syntexinae: Eosyntexis and Cretosyntexis completely lacks this vein, while Parasyntexis and Dolichosyntexis has this vein fully developed. But in recent genus Syntexis this character is polymorphic, some specimens have 1r-rs complete, others have it partly developed like in Curiosyntexis. The new genus also differs from Cretosyntexis in having Rs+M furcates at the level of 1m-cu; from other genera excluding Syntexis in having pterostigma widely unsclerotized; from Syntexis and Parasyntexis in having short ovipositor.

Description: Shell medium in size (L up to 53 and H up to 38mm), elongated, equivalve; anterior margin slightly convex, ventral side smoothly and broadly rounded, posterior side convex in the middle part and wider than the anterior part, without a postero-ventral fold.Umbones less flattened and concave, situated backwardly at slight anterior to the middle of shell. Radial ribs narrowed, rectangular in section, granulated with close and crossed crests that are rather strong in the anterior and central fields of the left valve and in the anterior field of the right valve; interspaces of radial ribs equal to the width of the ribs of the right valve and covered by low ridges continuing into the rib crest; the number radial ribs are 25-27. Ligamental area subtrigonal in shape, shorter and wider in the anterior part than in the posterior part, with four chevron grooves posteriorly and two anteriorly. Hinge plate narrow, the boundary between the anterior and the posterior series unclear. Periostracum brown and film-like on the ribs tops and ciliated along the rib interspaces.
