Leptothrips papago

description: Leptothrips papago Hood
Leptothrips papago Hood, 1939: 209.
Leptothrips acaciae Hood, 1939: 211. Synonymised by Johansen, 1987: 79. Leptothrips robustus Johansen, 1987: 47. Syn. n.
Leptothrips arizonensis Johansen, 1987: 76. Syn. n.
This species was based on a female holotype, with three female and one male paratypes, all collected from cottonwood, at Tucson, Arizona. Measurements of the antennae in the four species listed in the synonymy above are remarkably different. The length of antennal segments III+IV is 145 in the holotype of papago, whereas the measurements provided by Hood indicate only 107 for the holotype of acaciae. The similar measurement for the holotype of robustus is 130, and 110 for the holotype of arizonensis. No other character state differences have been found that correlate with this variation in antennal segment lengths. A further species in which these segments are unusually short is larreae, but in that species antennal segment III lacks a sense cone. Hood described acaciae from Wickenburg, Arizona, based on 17 females and one male collected from Acacia or Prosopis. Johansen described robustus from two specimens from Wyoming and one from Colorado, all three being mounted in Clarite. These specimens are thus seriously distorted, with the antennal sense cones almost completely eroded, and the fore wings of the holotype not available. However, one fore wing of the paratype from Wyoming clearly has no duplicated cilia. Johansen distinguished arizonensis from papago in a key, indicating that the eyes were not prolonged ventrally in the first but prolonged in papago. However, the difference in dorsal and ventral lengths of the eyes in the available specimens is largely dependent on how horizontal the head is on a slide-mounted specimen. Johansen placed robustus in his Group Obesus, presumably because the tube of the holotype is wide at the base (Fig. 16). However, this specimen is mounted in clarite, and is thus crushed with the tube distorted. Individuals identified here as papago have been seen from a wide range of unrelated plants at sites between Utah and California, based on 100 slides in ERMR; the recorded plants include members of the following genera: Adenostema, Ceanothus, Chrysothamnus, Hymenochloa, Purshia and Quercus.

Zygothrips floridensis Watson, 1922: 22. Synonymised by Johansen (1987: 97).
Described from Florida, and recorded from Virginia and Maryland, in association with species of Pinus, there are specimens in ERMR from Texas, taken on Pinus taeda at Smithville, and on Pinus sp. at Blossom. The following have also been studied (in USNM): one specimen from Arizona, one from Georgia, five from New York and three from South Carolina. This species shares with singularis the presence of only two sense cones on the fourth antennal segment. The pronotum lacks sculptured striae medially but is strongly striate anterolaterally, the fore wing is pale at the base, but the apex of antennal segment III is shaded brown.

Leptothrips purpuratus

description: Leptothrips purpuratus (Hood)
Haplothrips purpuratus Hood, 1925: 101.
Described from one female and one male, taken on a species of Atriplex at Tempe, Arizona, this species was described as having antennal segments III–VI “bright yellow”. The fore tarsus bears a small tooth on the inner margin, as in distalis and fasciculatus, and it shares with distalis the presence of strong transverse striae on the pronotum but lacks mid-lateral setae. In contrast, fasciculatus has a smooth pronotum, and purpuratus is unique among the three species of the distalis group in lacking a sense cone on antennal segment III. Specimens have been studied from Arizona (Sacaton), California (Tecopa, Thermal, Victorville), New Mexico (Rodeo) and Texas (Ysleta).

description: Leptothrips singularis Hood
Leptothrips singularis Hood, 1941: 149.
Described from three females and five males collected at Pine Key, Florida, this species is similar to pini but has the pronotum and hind tibiae paler. These two both have only two sense cones on antennal segment IV, but both are known from too few specimens to be sure that this character state is constant. A further species from Florida that is similar in structure and lacks sculpture lines across the pronotum is cassiae.

Type material. Holotype: ♂ from Estação Científica Ferreira Penna [01°42'24"S, 51°27'34.3"W], Floresta Nacional de Caxiuanã, Melgaço, Pará, Brazil, 14.IV.2006, J.A.P. Barreiros leg. (MPEG 29052).
Etymology. Noun in apposition taken from type locality. The final -n is added in order to mimic phonetics of the name of the locality.
Diagnosis. The embolic disc (with long dPED of rounded tip, prolaterally projected and short vPED ventrally projected; Figs 4 C, 6C) and pattern of scales on the carapace of A. caxiuanan sp. nov. (Fig. 5 A) are similar to those of A. mysticetus sp. nov. (Figs 1 A, 2A, 2C). However, A. caxiuanan sp. nov. can be distinguished from this species in having RvTA with rounded tip (Fig. 6 D), and a straight RTA (Fig. 6 B), while A. mysticetus sp. nov. has triangular RvTA tip (Fig. 4 D) and the RTA with the tip prolaterally curved over the cymbium (Fig. 4 B). In addition, it also differs from A. mysticetus sp. nov. by the curved, proximal, dorso-prolateral projection of the cymbium (Fig. 6 B), and a retrolateral depression on cymbium wherein the RTA fits (Fig. 6 D).
Description. Male holotype (MPEG 29052). Total length: 2.43. Carapace with a longitudinal stripe of white scales on carapace and tufts of brown scales laterally (Fig. 5 A), 1.33 long, 0.93 wide and 0.65 high. Ocular quadrangle 0.65 long. Anterior eye row 0.99 wide, posterior 0.84 wide. Legs: unknown (I–II lost). Length of leg III 2.44 (0.80 + 0.80 + 0.84); IV unknown (0.74 + 0.87 + broken). Palp (Figs 6 A–D): femur with a shallow distal depression, where the proximal tegular lobe fits when the palp is flexed (Fig. 6 A); embolic filament short, about half the length of the straight, sclerotized portion (Fig. 6 C). Color in alcohol: thoracic area dark brown and cephalic area black; abdomen dorsally brown and variegated; ventrally pale; legs brown (Fig. 5 A–B).
Female. Unknown.
Distribution. Known only from the type locality (Brazil, Pará) (Fig. 29).

Type material. Holotype: ♂ from Juruti, 02°30'27.4"S, 56°10'39.5"W, Pará, Brazil, 18–23.II.2011, B.V.B. Rodrigues leg. (MPEG 32687).
Etymology. A Latin noun meaning pillow, in reference to the modified RTA.
Diagnosis. The embolic disc and embolus of A. pulvinus sp. nov. are similar to those of A. argentinensis: the short dPED points prolaterally and the vPED points retrolaterally. However, the vPED of A. pulvinus sp. nov. arises from prolateral border of the embolic disc (Fig. 8 C), while in A. argentinensis it arises from the middle of the distal portion of the disc (see Galiano 1997: fig. 10). In addition, A. pulvinus sp. nov. has RvTA and ITA bladeshaped, and a RTA linked to a pillow-like membrane (black arrows in Figs 8 B, 8D), whereas in A. argentinensis the RvTA is trapezoidal with three apical teeth, and both the ITA and the pillow-like membrane are absent (see Galiano 1997: figs 8, 11). Amphidraus complexus also has the pillow-like membrane, but differs from A. pulvinus sp. nov. in having one less projection in the embolic disc and a different shape of the tibial apophyses (see Zhang & Maddison, 2015: figs 211, 212).
Description. Male holotype (MPEG 32687). Total length: 2.55. Carapace 1.25 long, 0.84 wide and 0.65 high. Ocular quadrangle 0.67 long. Anterior eye row 0.87 wide, posterior 0.72 wide. Legs: 431 = 2. Length of leg I 1.90 (0.57 + 0.68 + 0.65); II 1.90 (0.57 + 0.68 + 0.65); III 2.47 (0.72 + 0.84 + 0.91); IV 2.62 (0.76 + 0.87 + 0.99). Palp (Figs 8 A–D): cymbium with a proximal, retrolateral depression, where the pillow-like membrane of tibia fits (Fig. 8 D); tegulum with slight RSDL and tegular lobe prolaterally curved (Fig. 8 C); embolic filament very short, less than a quarter the length of the straight, sclerotized portion (Fig. 8 C). Color in alcohol: thoracic area brown and cephalic area black; abdomen dorsally brown and variegated; ventrally pale; legs light brown (Figs 7 A–B).
Female. Unknown
Distribution. Known only from the type locality (Brazil, Pará) (Fig. 29).

Type material. Holotype: ♂ from Estação Ecológica da Universidade Federal de Minas Gerais, 19°52’S, 43°58’W, Belo Horizonte, Minas Gerais, Brazil, VII.1999 – II.2001, E.S.S. Álvares et al. leg. (IBSP 32545). Paratype: 1♂, same data as holotype (MPEG 32763).
Etymology. Noun referring to the type locality (Belo Horizonte), in the way the name of the city is pronounced by some local people.
Diagnosis. A. belzonte sp. nov. differs from all Amphidraus species by the bifid tegular lobe (when seen laterally, Fig. 10 A), the ITA emerging from proximal portion of the tibia (Figs 10 B, 10C, 10D), the flattening of the embolus in its initial portion, its emerging point in the median portion of the embolic disc (Fig. 10 C), and the conspicuous distal cavity on the femur, in which the proximal tegular lobe fits when the palp is flexed (Fig. 10 A). In other Amphidraus species, the ITA emerges from the distal region of the tibia, the emerging point of the embolus is proximal, and the distal cavity of the femur is less conspicuous.
Description. Male holotype (IBSP 32545). Total length: 2.89. Carapace 1.48 long, 0.95 wide, 0.68 high. Ocular quadrangle 0.72 long. Anterior eye row 1.03 wide, posterior 0.91 wide. Legs: 4312. Length of leg I 2.51 (0.76 + 0.95 + 0.80); II 2.36 (0.76 + 0.84 + 0.76); III 2.97 (0.95 + 0.99 + 1.03); IV 3.28 (1.00 + 1.10 + 1.18). Palp (Figs 10 A–D): RvTA short and rounded, RTA retrolaterally projected, with tip curved towards ventral side, and ITA retrolaterally projected (Figs 10 B–D); cymbium with proximal, retrolateral cavity, in which the RTA fits (Fig. 10 D); embolic disc well developed, with two acute processes, one of them longer, emerging from the distal region of the disc, projected to the prolateral side, and the other shorter, emerging at the middle of distal part of the disc and projected to the retrolateral side (Fig. 10 C); embolic filament very short, less than a quarter the length of the straight, sclerotized portion (Fig. 10 C). Color in alcohol: thoracic area brown and cephalic area black; abdomen dorsally brown and variegated; ventrally pale; legs light brown (Figs 9 A–B).
Female. Unknown.
Distribution. Known only from the type locality (Brazil, Minas Gerais) (Fig. 28).

Etymology. A composed Latin noun (nigri + genu), meaning “black-knee”, in reference to the dark markings on the middle portion of the legs.
Diagnosis. The embolic disc and embolus of A. nigrigenu sp. nov. are similar to those of A. duckei, A. santanae, A. colombianus and A. simplex sp. nov.: there are two dPED and the vPED is proximal and projects retrolaterally; also, the embolus is thicker and sickle-shaped in these species (Fig. 12 C). However, A. nigrigenu sp. nov. can be distinguished by the short and rounded RvTA with two teeth on the border (Fig. 12 D), being slender and sinuous in A. duckei and A. colombianus, short with one tooth in A. santanae (see Galiano 1967: fig. 4), and finger-shaped in A. simplex sp. nov. (Fig 14 D).
Description. Male holotype (MPEG 32688). Total length: 2.93. Carapace 1.44 long, 1.03 wide and 0.80 high. Ocular quadrangle 0.57 long. Anterior eye row 1.10 wide, posterior 0.91 wide. Legs: 3412. Length of leg I 2.20 (0.72 + 0.76 + 0.72); II 2.16 (0.72 + 0.76 + 0.68); III 2.96 (0.95 + 0.95 + 1.06); IV 2.92 (0.87 + 0.95 + 1.10). Palp (Figs 12 A–D): femur with subproximal ventral projection (Figs 12 A, 12D); tibia with reduced RTA and depression below the apophyses (Figs 12 B, 12D); embolic filament longer than straight, sclerotized portion (Fig. 12 C). Color in alcohol: thoracic area brown and cephalic area black; abdomen dorsally almost black; ventrally pale; legs with dark spots (Figs 11 A, 11B).
Female. Unknown.
Distribution. Known only from the type locality (Brazil, Pará) (Fig. 31).
Note. Although we have found large variation in male palp structure of A. santanae, which could include the palp of the holotype of A. nigrigenu, we preferred to recognize this male as a different species, since the unusual morphology of the palp is accompanied by a different color pattern in legs and palps (black).

Type material. Holotype. ♂ from Lago Janauari, 03°20'S, 60°17'W, Manaus, Amazonas, Brazil, 16.XI.1989, J. Adis et al. leg. (INPA 5245).
Etymology. Noun in apposition taken from type locality.
Diagnosis. The male palp of A. janauari sp. nov. is similar to that of A. bochica, A. guatavita, A. pae, A. quimbaya, A. zipa and A. bifidus sp. nov., with only two short dPED (no vPED; Fig, 18C). Among these, A. janauari sp. nov. (Fig. 18 D) seems closer to A. guatavita (see Galvis 2017: fig. 5C) and A. bifidus sp. nov. (Fig. 21 D) by having similar RTA and RvTA (see note below). However, the projection on the basal portion of the embolus is absent in A. janauari sp. nov. (Fig. 18 C), rounded in A. guatavita (see Galvis 2017: fig. 5A) and bifid in A. bifidus sp. nov. (Fig. 21 C).
Note. The structure in A. janauari sp. nov. and A. bifidus sp. nov. named herein as the RTA was referred in A. guatavita by Galvis (2017) as DTS—dorsal tibial spur. On the other hand, Galvis’s RTA in A. guatavita is possibly homologous to the structure referred herein as RvTA. Nonetheless, the homology among these structures is yet to be determined.
Description. Male holotype (INPA 5245). Total length: 2.51. Carapace 1.20 long, 0.82 wide and 0.44 high. Ocular quadrangle 0.55 long. Anterior eye row 0.86 wide, posterior 0.65 wide. Legs: 3421; Length of leg I 1.51 (0.49 + 0.53 + 0.49); II 1.55 (0.49 + 0.57 + 0.49); III 1.79 (0.53 + 0.65 + 0.61); IV 1.75 (0.53 + 0.61 + 0.61). Palp (Figs 18 A–D): tibia with RvTA elongate and ventrally projected (Figs 18 C, 18D), RTA short and acute (Figs 18 B, 18D) and with small dorsal tubercle (Fig. 18 D); cymbium with large cymbial conductor (Fig. 18 C); embolic filament longer than straight, sclerotized portion (Fig. 18 C). Color in alcohol: thoracic area brown and cephalic area black; abdomen light brown; legs light brown (Fig. 17 A–B).
Female. Unknown.

Type material. Holotype: ♂ from Igapó Tarumã-Mirim [03°00’49.0”S, 60°10’33.5”W], Manaus, Amazonas, Brazil, 8.X.1987, unknown leg. (deposited in INPA).
Etymology. Epithet to be treated as a compound Latin noun (loxodonta, the African elephant + the alternative suffix -illus to create the diminutive), in allusion of the shape of the embolic disc and embolus, which, seen upside down, create the image of a young elephant with large ear (the disc) and long trunk (the embolus).
Diagnosis. The embolic disc and embolus of A. loxodontillus sp. nov. are similar to those A. semicanus, with a rounded dPED (Fig. 26 C). However, A. loxodontillus sp. nov. differs from this species in having a small-sized embolus apical filament (Fig. 26 C), while in A. semicanus it is very long and spiralled (see Galiano 1963: lám. XXVII, figs 15–16). In addition, the male palpal tibia of A. loxodontillus sp. nov. has two apophyses, while it has a single, wide apophysis in A. semicanus (Fig. 26 D; see Galiano 1963: lám. XXVII, fig. 15).
Description. Male (deposited in INPA). Total length: 2.51. Carapace 1.29 long, 0.84 wide and 0.53 high. Ocular quadrangle 0.65 long. Anterior eye row 0.87 wide, posterior 0.76 wide. Legs: 4312. Length of leg I 1.90 (0.61 + 0.72 + 0.57); II 1.86 (0.65 + 0.68 + 0.53); III 2.11 (0.70 + 0.65 + 0.76); IV 2.47 (0.76 + 0.80 + 0.91). Palp (Figs 26 A–D): femur with poorly developed distal ventral depression; embolic filament short, slightly longer than half the length of the straight, sclerotized portion. Color in alcohol: thoracic area dark brown and cephalic area black; abdomen dorsally brown and variegated; ventrally dark brown; legs brown (Figs. 25 A–B).
Female. Unknown.
Distribution. Known only from the type locality (Brazil, Amazonas) (Fig. 29).
Misplaced species. The type species of Nebridia (N. semicana Simon, 1902) was transferred to Amphidraus by Zhang & Maddison (2015). Consequently, Nebridia was synonymized with Amphidraus. In addition to the type species, Amphidraus currently includes three other species transferred from Nebridia, namely A. manni, A. mendicus and A. parvus, whose morphology did not correspond to that of true Amphidraus and are discussed below.

Distribution. Known only from the type locality (Argentina, Misiones)
Note. The genus Titanattus belongs in the clade Amycoida and is nested within a smaller clade including scopocirines, sarindines and thiodinies (See Ruiz & Maddison 2015, clade 2). The new combination is based on the similarity with the species referred to as “ Titanattus sp. D” in Ruiz & Maddison (2015), which is being described by Bustamante & Ruiz (2017, in press). New diagnostic illustration of the holotype of T. parvus is provided herein (Fig. 27 E).

description: Truncattus Zhang & Maddison, 2012
Truncattus ZHang & Maddison, 2012b: 47 (type species: Truncattus flavus ZHang & Maddison, 2012, original designation).
Diagnosis. Truncattus Zhang & Maddison, 2012 is similar to Antillattus Bryant, 1943 and Emathis Simon, 1899. It differs from Antillattus by the unmodified male chelicerae and endites, and from Emathis by the bicuspid retromarginal tooth on the chelicera (three or more cusps in Emathis). It is also similar to Caribattus Bryant, 1950 in color pattern, but can be distinguished by the bicuspid retromarginal tooth in Truncattus (Caribattus has one unident retromarginal tooth), and the presence of a proximal tegular lobe on the male palp (absent in Caribattus) (Zhang & Maddison 2012b: 47).

Description. See Bryant (1943).
Note. A. manni and A. mendicus are clearly members of the euophryines by the spiraled embolus and the well developed RSDL, but differ from Amphidraus, which does not have a well developed RSDL, by a simple RTA and an embolic disc poorly developed, with no processes (Figs 27 A, 27C). These species share great similarity with the species of the Antillattus -clade, composed of Antillattus, Petemathis Prószyński & Deeleman-Reinhold, 2012 and Truncattus, which is restricted to the Caribbean Islands (see Zhang & Maddison 2015). The species of this clade usually have two promarginal teeth (see Zhang & Maddison 2015: figs 58, 65, 66, 73, 75, 88, 94) and a coiled embolus of no more than half a circle (see Zhang & Maddison 2015: figs 50, 57, 64, 72, 80, 87, 93). Among the genera of this clade, A. manni and A. mendicus share more morphological similarities with Truncattus in having the chelicera with one bicuspid retromarginal tooth and with a retrolateral depression on the chelicerae (Figs 27 B, 27D; see Zhang & Maddison 2012b: fig. 260; Zhang & Maddison 2015: Fig. 94), and the male palp with a large proximal tegular lobe (Figs 27 A, 27C; see Zhang & Maddison 2012b: figs 240, 249, 259). Based on this evidence, these two species are herein transferred to Truncattus.

Cryphocricos breddini: Usinger 1947, Ann. Entomol. Soc. Amer. 40:341 (corrected generic spelling).
Type repository: Naturmuseum Senckenberg (Frankfurt, Germany).
Type locality: Ecuador: Balzapamba. Balzapamba is both a municipality and town in Bolívar Province. Río Cristal and its tributary Quebrada Chorrera appear to be the most likely streams from which the type specimen was collected.
Discussion: The type specimen is a macropterous male in good condition; however, it is covered with debris (Figs. 5–6). Females and brachypterous specimens are unknown. Usinger (1947) considered macropterous adults from Peru to be indistinguishable from the type, and thus associated brachypterous individuals with it; he then included the use of hemelytra shape to distinguish these brachypters from congeners. However, hemelytral shape is not a consistent attribute in Cryphocricos hungerfordi (Sites 1990) and probably other species. Thus, diagnostic features for C. breddini remain unknown, although Lopez Ruf (1991) presented a detailed diagnosis of specimens from Parque Nacional Baritu in Salta, Argentina, based in part on Usinger (1947).
Diagnosis: Little information is available to apply as diagnostic features because the only authoritatively identified specimen is the macropterous male holotype. Montandon (1911) reported length to be 10 mm and maximum width 4.2 mm. Because macropters differ in size and shape from brachypters, interspecific comparisons mixing morphs is not reasonable. Nonetheless, Usinger (1947) keyed this species using length less than 11 mm and assumed the brachypterous form would be “not or scarcely half as wide as long.”

(Figs. 7–8)
Cryphocricus daguerrei De Carlo 1940: Rev. Soc. Entomol. Argentina 11:430–431 (misspelling of genus).
Type repository: Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” (Buenos Aires, Argentina).
Type locality: Argentina: Entre Ríos Province, Concordia.
Discussion: The holotype is a brachypterous male with only the right foreleg intact. The left foreleg and right hindleg are complete only through the femur, the left middle leg is complete through the tibia, and the right middle leg and left hindleg are missing (Figs. 7–8). The rivers in Concordia are wide, flat, and muddy, which are not suitable conditions for Cryphocricos; thus, if indeed the type specimen was collected there, river dynamics probably have changed since its collection in 1931. De Carlo (1968) proposed an allotype from Uruguay; however, this is not permissible under the rules of the ICZN, and Lopez Ruf (1991) challenged the accuracy of the identification based on differences in color, pronotum, and head shape with those of the holotype.
Diagnosis: De Carlo (1941) offered the diagnostic character of abdominal segments II and III (he probably meant III and IV) lateral margins individually slightly curved; thus, creating a non-uniform curvature of the entire abdominal lateral margin. This species differs from C. rufus De Carlo, 1940 by its smaller size, the shape of the hemelytra, the concavity in the prothoracic anterior margin, the shape of the head, and fewer granulations (=tubercles) (De Carlo 1940). This species differs from C. fittkaui by its darker color and the female subgenital plate is very similar, although it has its differences (De Carlo 1967). The female subgenital plate was illustrated with the lateral margins sinuate and the posterior margin to have three distinct lobes, with the middle lobe half the length of the lateral lobes, and is comparable to that of C. fittkaui (De Carlo 1968).

Type repository: Zoologische Staatssammlung München (Munich, Germany).
Type locality: Peru: Tingo Maria, Rio Rondos, and Rio Azul.
Discussion: The holotype is an intact brachypterous male (Fig. 9) and the allotype is a brachypterous female missing the tarsus of the right hindleg (Fig. 10). Two additional paratypes are at housed at the type repository.
Diagnosis: This species differs from C. daguerrei by its generally light-brown color and the female genital operculum (=subgenital plate) is very similar, although it has its differences; it differs from C. peruvianus De Carlo, 1940 especially by its larger size (De Carlo 1967). I have examined the allotype and topotypes from Tingo Maria; the female subgenital plate has three distinct elongate lobes, similar to those of C. daguerrei, and elongate posterolateral spines of abdominal segments VI and VII (female) or V (male).

Cryphocricos granulosus De Carlo 1967: Amazoniana 1:190–191.
Type repository: Zoologische Staatssammlung München (Munich, Germany).
Type locality: Brazil: Rio Grande do Sul.
Discussion: The holotype is a brachypterous male (Fig. 11) and the allotype a brachypterous female with heavy glue residue ventrally on the right side of the pterothorax (Fig. 12), evidently to hold the specimen to the pin. Eighteen additional paratypes are at ZSM. Ectosymbiotic flatworms, Temnocephala minutocirrus Amato, Seixas & Amato, 2007, were found on 33% of C. granulosus specimens collected from Arroio Forqueta in Rio Grande do Sul, Brazil (Amato et al. 2007). Previously, the only report of Temnocephala on saucer bugs was on several species of Limnocoris, also in Brazil (Vianna & de Melo 2002).
Diagnosis: De Carlo (1967) reported this species to be very characteristic mainly due to the numerous granules (=tubercles) on the dorsal part of the body, which are not observed in C. vianai De Carlo, 1951, which has the same color, but the anterior femora are slightly less wide and the female subgenital plate at the distal end is recessed on the sides, with a slight protruding curve in the middle; it differs from C. rufus by color and because granules (=tubercles) are more dispersed in it.

(Fig. 18)
Cryphocricos hungerfordi Usinger 1947: Ann. Entomol. Soc. Amer. 40:337–338.
Type repository: Snow Entomological Museum Collection (Lawrence, Kansas).
Type locality: Mexico: Veracruz, Tantoyuca.
Discussion: The holotype is a brachypterous male (Fig. 18). The southern extent of the range of C. hungerfordi into Central America is not clear. It extends from Kimble County in central Texas, south at least to Chiapas in southern Mexico (Sites & Nichols 1993). Usinger (1947) described the markedly smaller species C. latus and C. obscuratus from Costa Rica and Panama, respectively, distinguishing them by body proportion differences as well as overall length. However, when studying populations of Cryphocricos from Belize, Sites et al. (2018) were unable to assign a specific identity to them because of high intraspecific variability as some populations had individuals that keyed to three species, including those from Costa Rica and Panama. Thus, C. hungerfordi might extend further southward into Mesoamerica and possibly be synonymous with one or both Central American species.
The immature stages of C. hungerfordi were described and illustrated, including the structure of eggs, which can have three to five micropyles (Sites & Nichols 1993). In central Texas, C. hungerfordi is bivoltine and overwinters as third through fifth instars and adults among large rocks in fast water (Sites & Nichols 1993). Microhabitat partitioning of this species and two other saucer bugs was investigated in the South Llano River in central Texas. Eight of ten abiotic variables were significant in accounting for quadrats in which C. hungerfordi occurred; rock standard error of the mean accounted for 43.1% of the variation in density (Sites & Willig 1991). In a stream simulation study using flow tanks to determine habitat preferences of three species of naucorids, C. hungerfordi preferred cobble over either gravel or pebble substrates; however, a synergistic effect was detected between current velocity and substrate particle size (Herrmann et al. 1993).
Diagnosis: This species differs from most of the South American species in having the posterolateral corners of abdominal segments V (♂) and VI and VII (♀) not acuminate, but right-angled or blunt. Usinger (1947) distinguished it from C. latus and C. obscuratus by its length greater than 7.5 mm, and from C. mexicanus Usinger, 1947 by wider embolia and longer body, hemelytra, and claval commissure.

(Fig. 19)
Cryphocricos latus Usinger 1947: Ann. Entomol. Soc. Amer. 40:340–341.
Type repository: Snow Entomological Museum Collection (Lawrence, USA).
Type locality: Costa Rica: San Isidro del General, 2,000 ft.
Discussion: The holotype is a brachypterous male (Fig. 19) and allotype a brachypterous female. Seven brachypterous paratypes also are housed in the Snow Museum. The macropterous male and female were described by Herrera & González (2013). Cryphocricos latus is associated with fast current, large rocks, and coarse pebbles (Stout 1981). These tropical streams are subject to severe seasonal spates, which result in a high rate of downstream displacement of C. latus followed by a slow recolonization rate (Stout 1981). Because the macropterous form is uncommon except in the dry season, its ability to recolonize upstream following a spate is temporally limited (Stout 1982).
Diagnosis: This species is similar to C. obscuratus in “all characters” but differs from it by a wider body/length ratio, length> 7 mm, and claval commissure subequal to the length of the scutellum (Usinger 1947). Specimens that I have examined from Costa Rica and Panama readily conform to characteristics of both species; thus, I suspect that C. latus and C. obscuratus are conspecific. Moreover, specimens of Cryphocricos from Guatemala and Belize also are small, and those from Belize had body width/length ratios suggesting a C. latus identity, but body lengths spanned those of three species (C. hungerfordi, C. latus, and C. obscuratus) (Sites et al. 2018); thus, considerations of conspecificity must also include C. hungerfordi.

(Fig. 20)
Cryphocricos mexicanus Usinger 1947: Ann. Entomol. Soc. Amer. 40:335–337.
Type repository: California Academy of Sciences (San Francisco, USA).
Type locality: Mexico: Estado de México, District of Temascaltepec, Temascaltepec.
Discussion: The holotype is a brachypterous male (Fig. 20) and allotype a brachypterous female. Several additional paratypes are at housed at the type repository. The type series was collected by Hinton and Usinger in a small rushing stream with small pebbles and rocks by holding a net downstream while turning over and brushing rocks (Usinger 1947). They collected 140 specimens of nymphs and brachypterous adults, but no macropterous adults. In Tejupilco, 48 km southwest of the type locality, Hinton and Usinger collected one male and three female macropterous specimens in the riffles of a swiftly flowing stream. This site was 2000 feet lower in elevation than the type locality.
Diagnosis: Usinger (1947) distinguished C. mexicanus from C. hungerfordi by the shorter body length, hemelytra, and hemelytral commissure, and narrower embolium. Specifically, the hemelytral commissure is half the length of the scutellum, whereas in C. hungerfordi they are subequal. In comparison with C. barozzii, this species is smaller, has a shorter anteocular part of the head, shorter hemelytral commissure, and blunt apical connexival corners (Usinger 1947). Small differences in body length are not reliable interspecific descriptors in this genus; however, the short hemelytral commissure is readily apparent and diagnostic.

Cryphocricos obscuratus Usinger 1947: Ann. Entomol. Soc. Amer. 40:338–340.
Type repository: California Academy of Sciences (San Francisco, USA).
Type locality: Panama: Colón Province, 6 miles east of Porto Bello, XX Plantation. The type series was most likely collected in Río Cascaja.
Discussion: The holotype is an intact brachypterous male (Fig. 21). The allotype and two other specimens from the same collection are in the type repository. One paratype is in the Essig Museum, University of California, Berkeley. There is no mention of C. obscuratus in the literature beyond the original description other than its inclusion in the La Rivers (1971) and Herrera (2013) catalogs.
Diagnosis: Usinger (1947) reported this species to be the smallest described at the time with the holotype male measuring 6.53 mm and female 6.5 mm. In comparison to C. barozzii and C. breddini, the anteocular portion of the head is shorter and body size smaller (Usinger 1947). It differs from C. mexicanus by its smaller size, darker color, and rounded and more coarsely crenulate lateral margins of the pronotum. Further, the posterolateral corners “are less strongly produced posteriorly, the disk of the pronotum is without apparent depressions at the middle and the front femora are shorter and stouter” (Usinger 1947). In the key to brachypterous adults, C. obscuratus was distinguished from C. latus of Costa Rica by the body width less than half its length, the hemelytral commissure shorter than the scutellum, and length <7 mm (Usinger 1947).
