A NEW COCKROACH GENUS (GURNEYA)
PREVIOUSLY CONFUSED WITH PINACONOTA

Princis (1967) listed 2 species of Pinaconota, viz. bifasciata (Saus- sure) and obliqua (Walker). Ischnoptera ( ?) sicca Walker was synonymized by Kirby ( 1904) with bifasciata, but I ( 1973a) showed that Kirby was incorrect in his interpretation of the species and placed sicca in the new genus Alphelixia. The male genitalia and other morphological characters of obliqua indicate that this species is not a Pinaconota and a new genus is erected for it (see below). In describing Pinaconota, Saussure (1895) simply stated that the hind metatarsi were very short, with a fringe of long hairs, and a large apical pulvillus. Shelford's (1910) characterization of the genus is as follows: Form depressed. Pronotum trapezoidal, an- teriorly and posteriorly sub-truncate, deeply punctate. Scutellum exposed. Tegmina and wings fully developed, extending beyond the apex of the abdomen. Femora moderately spined beneath. Tarsi very short, fimbriate, and entirely unarmed beneath; posterior meta- tarsus equal in length to the two succeeding joints, its pulvillus large. Arolia very large. In this generic description, Shelford was appar- ently influenced by his belief that Ischnoptera ( ?) obliqua Walker was a Pinaconota.
Pinaconota can be recharacterized as follows: Pinaconota Saussure

large. Supra-anal plate rounded with a mesa1 indentation. Cerci short, reaching to about the hind margin of supra-anal plate. Sub- genital plate ( cf ) asymmetrical, broadly, but weakly concave on right side; styli about equal. Male genitalia: L2d a small irregu-
larly shaped sclerotized plate separated from L2vm; prepuce densely spicular in part, with or without large spines on the free margin (Figs. IS, 17, 20, 23. 291, 30; see Fig. 29 for naming of parts), a light sclerotized plate present ventral to the L2vm. The membrane
lying above the L2vm may have a number of small spines (Fig. 15) but in the flattened KOH preparations are not shown in their normal position (Figs. 20, 23). R2 unique in having a finger-like basal projection directed toward the inner curved margin of the hook (Figs. 16, 18, 21, 3 I ) . Right paraproct considerably more developed than the left (Figs. 13, 27-28).
The presence of large spines on the prepuce is, as far as I know, unique for a member of the Epilamprinae, and has only been found in the Blaberinae. However, in that subfamily the spines usually closely surround the L2d (Roth, igyoa). Because of the unusual genital structures, I place Pinaconota in the tribe Pinaconotini. The following is a redescription of Pinacon'ota bifasciata supple- menting that of Saussure:
Pinaconota bifasciata ( Saussure)

anal plate (Figs. 4, 13), flattened dorsally with few scattered setae, somewhat convex ventrally covered with many short and a few long setae. Subgenital plate asymmetrical, apex of hind margin subacute, the right side shallowly concave, styli about equal, not extending beyond the apex of the plate (Fig. 14). Leg armament as described for genus: Antero-ventral margin of front femur with 2-6 small but stout spines followed by a row of very small setae. Pulvilli very large, apical on the metatarsi, and covering practically the entire ventral surfaces of the other tarsal segments; arolia very large. Genital phallomeres shown in figures 15-23 : Lad an irregu- larly shaped sclerotized plate separated from L2vm (Figs. 15, 17, 20, 23) ; preputial membrane modified into a densely spicular area with 3 or more large spines; a pale sclerotized plate continues beyond the dense spicular area (Fig. 15) ; the membrane above L2vm with many small spines ; LI with a deep, heavily sclerotized, upcurved cleft, the upper lobe smaller than the lower lobe which lacks setae (Figs. 19, 22). R2 strongly curved, the apex partly membranous, enlarged, a large finger-like projection extending from the base toward the inner margin of the curved portion (Figs. 16, 18, 21 ). Measurements (mm) : Total length, I 5-1 6.5 ; pronotum length X width, 4.1-4.2 X 5.9-6.2; tegmen length, 12-12.5 (macropterous). 7.6 (brachypterous) .
Coloration: Face (Fig. 3) brownish to black, followed by a broad testaceous band just above the antenna1 sockets, then a broad brownish to black band connecting the tops of the eyes and followed again by testaceous; basal half of clypeus testaceous. Antennae more or less unicolorous throughout, or with basal segments yellowish brown, the remainder darker. Pronotum and tegmina semi-hyaline to subopaque, the less transparent specimens whitish-yellow, the others testaceous. Pronotum with an irregularly shaped, arched, longitudinal, light to dark brownish band on each side of the mid-line, not reaching the borders, but converging posteriorly; surface sprinkled with a few to many brownish dots of variable size (Figs. I, 2, 5, 7). Humeral vein with a brownish stripe of variable length, the stripe solid (Fig. 5) or pale with dark lines on either side (Fig. I) ; right tegmen dark on the portion covered by the left tegmen (Fig. I). Tergites mostly dark, either solidly dark brown or interspersed with some pale areas, laterally with a broad testaceous or yellowish-white border, sprinkled with small brown dots; in the subopaque the seventh segment has a round brownish spot on each side (Fig. 4). Sternites dark brown with or without a lateral testaceous border

Measurements (mm) : Total length, 17-21; pronotum length X width, 4.2-5.5 X 6.5-8.2 ; tegmen length, 14-16 (ma~ro~terous) , 8.9 (brachypterous) .
Nymphs: Nymphs are brownish, and yellowish brown, the mark- ings differing with different instars (Figs. 10-12). Young and older stages have the characteristic head markings of the adult. The pro-, meso-, and metanotum are sprinkled with variable sized raised dots, a row of several elongated ones along the mid-posterior border just above the margin. A similar row of elongated granules along the hind margins of the abdominal tergites, the granules decreasing in size laterally, and smaller on the posterior segments. Material examined (All specimens from the US. National Mu- seum) :
d, 9 nymph, 2 d nymphs, Brazil (at San Francisco, I 7. XI. 1970, with bromeliads) ; 9, 8 nymph, Brazil (at Hoboken, 29, 30. X. 1940, with bromeliads) ; d and 9, Corupa (Hansa Humboldt) , S.

chids) ; brachypterous CJ and 9, Ilha das Alcatrazes, S. Paulo, Brazil.
I was not able to obtain Saussure's type 2 but the available macropterous specimens in general fit his description and figure. The pronotal markings of the brachypterous specimens were of a much lighter brown than the long-winged forms and the male preputial modification differed slightly (Fig. 20) from the others (Figs. 17, 23). It is possible that more than one species is represented in the above material but additional specimens, particularly of brachypterous forms are needed before this can be decided. Walker (1868) described the male of Panchlora inaequalis which Kirby (1904) listed under Tribonium, and which was laced in Proscrafea by Princis (1958). The male genitalia of Panchlora (Roth, r 97 r a), Tribonium spp. (Roth, I 970) and Proscratea com- 'The following changes should be made in the explanation of figures in my Zetoborinae paper (Roth, 1970) : p. 223, Fig. 18, Tribonium conspersum (Gukrin) should be Tribonium spectrum (Eschtz.) ; Fig. 19 should be 20; Fig. 20 should be 19 and Tribonium sp. should be Tribonium conspersum (Gukrin) ; page 234, shown in Fig. 19 should read 20; Tribonium conspersum should read Tribonium spectrum; p. 235, Tribonium sp. should read Tribonium conspersum and shown in Fig. 20 should read 19).
19741 Roth - Cockroach Genus Gurneya 295 planata (Perty) (Roth, 1973; type of genus, Princis, 1964)) are so different from inaequalis that it is unwarranted to place this species in any of these genera. The most unusual features of the genitalia of inaequalis are the R2 (Fig. 31) with a basal projection extend- ing toward the inner margin of the hook, and the densely setose preputial modification (Figs. 29, 30). The R2, L2d, and LI (Figs. 29-32) of inaequalis are remarkably similar to these structures of Pinaconota bifasciata (Figs. I 5-23). The prepuce in both have a large faintly sclerotized plate which lies under the L2vm; the pre- puce of inaequalis differs in lacking some large spines on the border and smaller ones on the membrane above L2vm. Although the color markings and size of Panchlora inaequalis differs from Pinaconota bifasciata (cf. Figs. I and 24)) the marked similarity in their genitalia and other characters indicates that the former species should be placed in Pinaconota.
The following is a redescription of Panchlora inaequalis supple- menting that of Walker.

Shelford ( 1907) stated that Ischnoptera ( ?) obliqua Walker "appears to be undoubtedly referable to the genus Pinaconota, Sauss. ; it can be distinguished from the only other species in the genus P. bifaxiata, Sauss., by its much larger size." P. obliqua differs markedly from bifasciata in femoral armature, relative length of cerci, bulging eyes, and <S genital phallomeres. Because of the morphological differences, especially in the 3 genital phallomeres, I am placing obliqua in a new genus characterized as follows: Gurneya n. gen.3
Type-species : Ischnoptera ( ?) obliqua Walker ( I 869, p. I 48) (present designation).
'Princis (1958) placed inaequalis in Proscratea. The femoral armament of a female of Proscratea complanata was as follows: Anterior and posterior margins of front femur unarmed except for 1 distal spine on each; genicular spine absent. Both margins of mid femur unarmed; distal spines lacking; genicular spine present. Anterior margin of hind femur unarmed; hind margin with 3 widely spaced heavy spines; distal spines absent, genicular spine present.
'The genus is named in honor of Dr. Ashley Gurney, orthopterist at the United States National Museum, who has helped me considerably in my taxonomic studies of the Blattaria.
(3'. Vertex, face, and pronotum deeply punctate (Figs. 34-35). Entire ventro-anterior margin of fore femur armed with a row of small, bimarginally serrated, closely spaced spines, lacking a large distal spine (Fig. 36) ; ventro-anterior margin of mid femur similarly armed but the spines fewer and not uniformly spaced. Tarsi very short, fimbriate, unarmed beneath. Supra-anal plate rounded, entire. Cerci long, extending well beyond hind margin of supra-anal plate (Fig. 38). Subgenital plate asymmetrical, with a broad shallow incision on right side (Fig. 39). Styles equal, not extending beyond hind margin of subgenital plate (Fig. 39). Genital phallomeres; Lad absent, prepuce spiculate, otherwise unmodified (Fig. 40). R2 with a deep subapical incision which extends to about the middle of the hook (Fig. 41) ; LI with the upper lobe (above the cleft) elongate and more narrow than the lower (Fig. 42). In obliqua, the absence of an L2d and shape of the spicular sur- face of the prepuce (though lacking some long "silky" hairs on one side) resembles the same structure in Alphel'ixia (see Figs. 21 and 23, in Roth, 1973a). The hooked phallomere (R2) resembles this structure in certain genera of Epilamprinae (e.g. Litopeltis, see Fig. 37, in Roth, 1971) and Blaberinae (e.g. Blaptica, see Fig. 57, in Roth, 1970a). The shape and sclerotization of the LI differs from that found in the other genera with similar appearing R2's. Gurneya obliqua (Walker), n. comb.
