03F8813F217EFFA9A3A8522F9158F758.taxon	discussion	Comments. The genus Thyanta is closely related to two other pentatomine genera, Cyptocephala Berg and Tepa Rolston and McDonald, from which it can be separated reliably only by differences in the male genitalia. In all northern hemisphere species of Thyanta, the head of each paramere lacks a lateral lobe. In Cyptocephala and Tepa, the parameres have well-developed lateral lobes. Cyptocephala further differs from Tepa and Thyanta by having minute denticles between the lateral lobe and the apex of the paramere. The parameres of species of Tepa and Thyanta lack denticles. Jensen-Haarup (1928) described the subgenus Parathyanta within Thyanta. Rolston and McDonald (1984) placed Parathyanta in the synonymy of Cyptocephala. At the same time, they transferred 4 species from Thyanta to Cyptocephala and 6 species from Thyanta to Tepa. The species of both Cyptocephala and Tepa have been reviewed recently (Rolston, 1972, 1986; Rider, 1986 a). The genus Thyanta is divided into three subgenera: Argosoma Rider, Phacidium Breddin, and Thyanta. All 8 species of the subgenus Phacidium are restricted to South America and have been treated in an earlier paper (Rider and Chapin, 1991). Argosoma contains 20 species, 6 of which are known to occur outside South America. The nominate subgenus contains 9 species of which 7 are known to occur in the area covered by the present paper.	en	Rider, David A., Chapin, J. B.

03F8813F217CFFAEA3E859929452F991.taxon	discussion	Comments. Species of the subgenus Thyanta have the pygophoral opening subtended by a semicircular or rectangular impression, and the posterior margin is distinctly emarginate medially. Species of Phacidium have the posteroventral surface of the pygophore arcuately rounded or sulcate, and the posterior margin is not emarginate medially. The posteroventral surface of the pygophore in species of Argosoma is produced into a blunt, chin-like protuberance. The ectal surface of each paramere is concave in Argosoma and convex in both Phacidium and Thyanta. The female genitalia are also useful in separating species ofThyantaandPhacidium. In Thyanta, the distal end of the sclerotized rod is cone-shaped, and the spermathecal bulb is digitiform. In Phacidium, the distal end of the sclerotized rod is swollen subapically and narrowed distally, and the spermathecal bulb is globose. The female genitalia ofboth Phacidium and Argosoma are very similar, but females can usually be separated by dorsal punctation which is relatively dense in Phacidium and less dense and more coarse in Argosoma.	en	Rider, David A., Chapin, J.

03F8813F217BFFA2A32557E5950CFD62.taxon	discussion	Comments. Thyanta calceata can be separated from all other congeners except T. custator custator by the distinctly black anterolateral pronotal margins. It can be reliably distinguished from T. c. custator only by the male genitalia. In T. calceata, the pygophoral opening is subtended by a semicircular impression; this impression is rectangular in T. c. custator. Specimens of T. calceata are generally shorter and broader than specimens of T. c. custator, and the black markings on the anterolateral pronotal margins are usually darker and more extensive in T. calceata. These last two characters, however, may be apparent only when a series of specimens of each species can be compared. Most species of Thyanta occur in two color forms, a green form in the warmer months and a brown form in the cooler months. This is particularly well documented in T. calceata (McPherson, 1977 a, b, 1978 a, b; McPherson and Paskewitz, 1982; McPherson et al., 1983).	en	Rider, David A., Chapin, J. B.

03F8813F2177FFA1A09453B29672F98F.taxon	discussion	Comments. This species has been the subject of much confusion in the past. At one time the name T. custator was applied to nearly all specimens from the entire United States. Ruckes (1957 a) showed that the true custator form is confined to the coastal plain from Louisiana to Florida to New York, but he felt that it was a separate species distinct from the accerra form. The two forms have virtually identical genitalia. They cross-breed readily in the laboratory; and where their distributions overlap, specimens intermediate between the two forms are found fairly frequently. The two forms have a very narrow overlap in their respective ranges, however, and specimens taken from outside the area of overlap are usually easily identified. These two forms probably are more correctly considered subspecies. Thyanta c. custator and T. calceata are the only two species in the genus with distinctly black anterolateral pronotal margins. They can be separated reliably from each other only by the characters of the male genitalia. The pygophoral opening in T. c. custator is subtended by a rectangular impression, while this impression is semicircular in T. calceata. When large series are present, some separation can be made based on the general shape of the body: T. custator is slightly longer and narrower than T. calceata. Fortunately, there is very little overlap in their distributions.	en	Rider, David A., Chapin, J. B. (1992): Revision of the genus Thyanta Stal, 1862 (Heteroptera: Pentatomidae) II.

03F8813F216CFFBCA351538992D8F89D.taxon	discussion	Comments. Ruckes (1957 a) distinguished T. pallidovirens setosa from other U. S. Thyanta by the increased amount of pilosity on the legs and rostrum. This is a difficult character to discern. The brown autumnal-vernal forms of several other species and subspecies are also characterized by more and longer hairs on the same body structures (McPherson, 1979 a). Because T. p. setosa differs from the nominate subspecies in no other significant manner, T. p. setosa is placed as a junior synonym of T. pallidovirens. No reliable morphological character will consistently separate T. pallidovirens from T. custator accerra, as discussed in detail under the comments section of T. c. accerra. Basically, in the southwestern U. S. the two usually can be separated by the shape of the humeral angles, which are rounded in T. pallidovirens and angulate to spinose in T. c. accerra. In the northwestern U. S., the two species seem to be geographically isolated (Maps 3, 4).

Rider and Chapin (1991) made lectotype and paralectotype designations. All four specimens, which are housed in the Universetetes Zoologiske Museum (Copenhagen, Denmark), were examined. Rider and Chapin (1991) confirmed the status of Pentatoma fascifera Palisot de Beauvois, P. col / aris Westwood, Cimex transversalis Herrich-Schiiffer, Euschistus fasciatus Walker, and E. adjunctorWalker as junior synonyms. They also designated lectotypes for the latter two species. At one time Euschistus rubiginosus Dallas was considered a synonym of T. perditor. Rider (1986 b), however, examined the holotype of E. rubiginosus and determined that it was a senior synonym of Euschistus incus Rolston.	en	Rider, David A., Chapin, J. B.

The characters used to separate these species are sometimes subtle and hard to diagnose unless a series of specimens is available.

03F8813F2164FFB7A342545C9535F654.taxon	discussion	Comments. Thyanta spectabilis is very closely related to T. perditor, and may actually be a subspecies of that species. The genitalia of the two species are virtually identical; the only difference is that the parameres in T. spectabilis are somewhat larger than those in T. perditor. This is expected, however, since specimens of T. spectabilis are larger than those of T. perditor. The only reliable character to separate the two species is the orientation of the humeral spine. In T. perditor the humeral angle is directed anterolaterad, while in T. spectabilis it is directed primarily laterad and only slightly cephalad.	en	Rider, David A., Chapin, J. B.

It is often necessary to examine the male genitalia in order to make accurate determinations. Within geographical areas, the internal female genitalia are usually distinctive. This subgenus can be divided into two groups based primarily on the structure of the spermatheca. In T. boliviensis, T. brasiliensis Jensen-Haarup, T. emarginata Rider, and T. hamulata Rider, the sclerotized rod is somewhat elongate and lacks any subapical swelling. The remaining species have the sclerotized rod shorter and distinctly swollen subapically, becoming narrowed apically.	en	Rider, David A., Chapin, J. B.

Also, the vertex of the head is relatively flat, a character for which this species was named. The widening of the ostiolar canal is unusual, but not unique. It also occurs in Tepajugosa Van Duzee, a species with essentially the same distribution as Thyanta planifrons. The biological significance of this condition is not known, but would make an interesting study. This is the first record of this species from the United States.	en	Rider, David A., Chapin, J. B.

It is not possible to determine from his original description how many specimens he examined, but evidently he had more than one, as he mentions a variation. Only one syntype was located and examined. It is a 2 in poor condition (apex of abdomen destroyed, left forewing missing, etc.), but it does possess the characters that define this species. It has the following label data: (a) " maculatus " (b) " Thyanta maculata F., " and is here designated the lectotype. This specimen is housed in the Universetetets Zoologiske Museum (Copehagen, Denmark). Stal (1862 b) described T. casta from Mexico without designating a holotype or paratypes. One syntype, a! i!, was located and examined. Although it lacks the reddish markings that many specimens of T. maculata possess, it differs structurally in no significant manner from T. maculata. Because it is not possible to determine the number ofspecimens upon which Sill's description was based, the syntype specimen is designated the lectotype. It is labeled as follows: (a) " Mexico Coll.

03F8813F2159FF80A37D50969512FEA5.taxon	discussion	Commenis. Thyanta maculata was originally distinguished from other congeners by the presence of two oblong reddish macules, one on each side of the middle of the pronotum. Fewer than half the specimens of T. maculata actually exhibit this character. Also, several other species of Thyanta are known to have the same type of maculation in at least some specimens (T. pseudocasta Blatchley, T. brasiliensis Jensen-Haarup, T. curvata Rider). Thyanta maculata can be separated from other congeners except T. pseudocasta by the structure of the male genitalia. Each paramere is rather robust with the apex rounded, and the dorsomedial concave surface is oriented more mediad than dorsad. Thyanta pseudocasta has very similar male genitalia, but the aedeagus is slightly different. The aedeagus of T. maculata has a dorsomedial conjunctival lobe, while the same structure is apparently absent in T. pseudocasta. The two forms can usually be separated based upon the prominence of the humeral angles. Each humeral angle in T. maculata is usually produced beyond the base of the adjacent corium by less than half the width of an eye, while in T. pseudocasta each humeral angle usually protrudes beyond the corium by more than half the width of an eye. Thyanta maculata is a variable species, especially with respect to size and coloration. For example, specimens from the Yucatan peninsula ofMexico average much smaller than specimens from other parts of the range, but they do not differ in any other significant manner.	en	Rider, David A., Chapin, J.

The shape of the emargination in the posteromesial angle of each basal plate of the female is distinctive. Thyanta emarginata and T. excavata both have the posteromesial angles of the basal plates deeply emarginate, but the sides of the resulting concavity are nearly parallel, not divergent as in T. vadosa. The male genitalia are also distinctive. Thyanta vadosa is the only species with the apex of each paramere not only acutely angulate (almost acuminate) but also straight or bending slightly ventrad. In the maculata group, all other species having the apex of each paramere acute to acuminate also have the apex bending dorsad.	en	Rider, David A., Chapin, J. B.

In 1930, however, he designated 15 specimen as " type " (lectotype). He did not mention any of the other syntypes. Although actual paralectotype designations were not made, according to the International Code of Zoological Nomenclature (Ride et al., 1985, sect. 74 a [iv]), once the lectotype is designated the remaining syntypes automatically become paralectotypes. Accordingly, no such designations are needed, but labels have been added to the specimens to indicate their actual status. Regrettably, the d lectotype is in deplorable condition; all that remains is the head and pronotum. It has the following label data: (a) " Miami Fla. W. S. B. Coll. 3 - 11 - 24 " (b) " Purdue Blatchley collection " (c) " TYPE " (d) " Thyanta pseudocasta Blatchley. " The lectotype is deposited in the Purdue University Collection (W.

03F8813F2153FF85A088536F967BFC73.taxon	discussion	Comments. Thyanta pseudocasta can be separated from all congeners except T. maculata because the concave surface of its paramere is oriented more mediad than dorsad. Thyanta pseudocasta may actually be a subspecies of T. maculata. The male genitalia of the two species are very similar, but there are some differences in the aedeagus. Thyanta maculata has a prominent dorsomedial conjunctiva! lobe, while this structure is apparently absent in T. pseudocasta. Also, the humeral angles are more prominent in T. pseudocasta. Because these species represent reproductively isolated populations, a conservative approach is taken, and they are retained as full species.	en	Rider, David A., Chapin, J. B.

Thyanta testacea is very closely related to the other species in the maculata group, and can be reliably identified only by examination of the male genitalia. The apically acute parameres curving gently dorsad will separate it from all congeners except T. patruelis, which it closely resembles. The chin-like protuberance on the posteroventral surface of the pygophore is somewhat less prominent in T. testacea than in T. patruelis. There does seem to be a geographical separation of the two forms with T. testacea restricted to northern South America and the Lesser Antilles, and T. patruelis occurring from northeastern Brazil and southern Peru southward.	en	Rider, David A., Chapin, J.
