New genera, new species, and new combinations in New World Cochylina (Lepidoptera: Tortricidae: Tortricinae) Author Brown, John W. text Zootaxa 2019 2019-09-17 4671 2 195 222 journal article 25519 10.11646/zootaxa.4671.2.2 978ec4b3-8d0e-4f47-8084-610b34b96759 1175-5326 3442344 8DA2FA3F-3629-4D10-92B0-671637D91DD4 Pogospinia Brown , new genus Type species: Pogospinia floridana Brown , new species , by present designation. Pogospinia is proposed for three species formerly placed in Spinipogon Razowski, 1967 , i.e., P. spinifera (Razowski, 1967) , new combination ; P. veracruzanus ( Razowski and Becker 1986 ) , new combination ; and P . signata (Razowski, 1967) , new combination ; and one new species described herein. The last is from southern Florida and appears to be the only U.S. representative of Pogospinia . Razowski (1994) referred to “two groups of species…” in Spinipogon , which I recognize as distinct genera. Although P. spinifera , P. veracruzanus , and the new species are convincingly associated by male genitalia, P . signata is known only from the female, and its genitalia are not like those of any other Spinipogon . Females of most (but not all) species of Spinipogon and Pogospinia have an unusual and characteristic spiny, truncate-cone-shaped process emanating from the corpus bursae (e.g., Razowski and Becker 1983 : figs. 111, 112), similar to that of Phalonidia and Gynnidomorpha Turner, 1916 . The male genitalia of the species included in Pogospinia are very similar, however, they can be distinguished most easily by the shape of the median process of the transtilla. Razowski and Becker (1986) provided three illustrations of the male genitalia of S. veracruzanus , all from Estación Biologia Las Tuxtlas in Veracruz , Mexico , and recognized two different “forms” which mostly likely represent different species. Diagnosis . Superficially, adults of Pogospinia ( Fig. 8 ) are similar to those of Spinipogon , Lorita Busck, 1939 , Cochylis , Thyraylia , and others, however, they usually are slightly smaller. The male genitalia ( Fig. 26 ) of Pogospinia are easily distinguished by the shape of the valva: the distal 0.3–0.5 is widely bifurcate with a broad, round- ed or squarish concavity between the termination of the costa and the termination of the ventral edge (sacculus) ( Fig. 26 ; also see Razowski & Becker 1986 : figs 103‒108). This shape is unique among Cochylina and distinguishes the three described species of Pogospinia for which males are known. Pogospinia appears to be most closely related to Spinipogon ; the two genera share similar socii, a similar median process of the transtilla, and fused arms of the vinculum, sometimes forming a weak saccus. In Spinipogon the valva are somewhat rectangular or parallel-sided and not bifurcate distally (see Razowski and Becker 1986 : figs. 109, 110; Razowski 1993 : figs 33, 34; Metzler and Sabourin 2002 : figs. 2a, b). The absence of cornuti in the vesica of Pogospinia is shared with a few other genera, including Spinipogon . Males of Pogospinia lack both a forewing costal fold a hindwing costal roll. Description . Head: Frons and vertex rough scaled; ocellus present; sensory setae of antenna 0.8–1.0 times flagellomere diameter in male, shorter in female; labial palpus porrect, length of all segments combined 1.0–1.2 times diameter of compound eye, segment III weakly exposed; maxillary palpus 1-segmented. Thorax: Posterior crest weak; lateral scales of metanotum hairlike. Forewing length 3.3–4.5 mm in male, 4.4–4.5 mm in female, length 2.5–2.9 times maximum width, slightly wider in female; costa gently arched from base, apex round, male without costal fold; termen straight, oblique; Sc ca. 0.5 wing length; R 1 originating near middle of discal cell; R 2 originating nearer R 3 than R 1 ; R 5 ending at costa; M 3 and CuA 1 separate; CuA 2 originating about 0.6 length of discal cell; CuP absent; A1+2 stalked at 0.4 length. Hindwing length 2.5–3.6 times width; costa straight, male without costal roll; apex rounded; termen concave between M 1 and M 2 ; Sc+R 1 about 0.6 wing length; Rs and M 1 stalked about 0.4 length of M 1 ; M 3 and CuA 1 separate; CuA 2 originating 0.65 length of discal cell; frenulum with one acanthus in male, two in female. Abdomen: Unmodified. Male genitalia ( Fig. 26 ) with uncus absent; socius rounded, broadly attached to top of tegumen, setose; transtilla well developed, median process variable from short and blunt to bifurcate, spined or minutely dentate; valva wide at base, bifurcate in distal 0.5‒0.7 with dorsal (costal) lobe and ventral (sacculus) lobe, each with well-developed field of strong spines; vinculum arms fused distally forming V-shaped saccus. Phallus large, slender, 0.8–1.3 times length of valva, pointed apically; vesica without cornuti. Female genitalia ( Fig. 40 ) with papillae anales weakly lobate, setose; length of apophyses anteriores ca. 0.8 times that of apophyses posteriores, apophyses anteriores connected to sclerotized sterigma; sterigma variable from complicated with dense patches of spiculation, and rounded V-shaped median process to simple with median sclerite; ductus bursae short, with colliculumlike sclerotized band, weakly differentiated from corpus bursae; corpus bursae variable, round to elongate, with minute spicules and a truncate-cone-shaped process of long spines; accessory bursa originating from anterior third of corpus bursae. Distribution and biology . The genus ranges from Brazil ( P. spinifera ) north through Mexico ( P. veracruzanus ) to Florida; it likely occurs in the Caribbean. Little is known of the life history of Pogospinia , however, P. floridana was reared (n = 3 individuals) by Don Davis from Anthernanthera maritima (Amaranthaceae) at Long Key State Park in southern Florida. Etymology . The genus name is close to, but not quite, an anagram of the related Spinipogon , and is feminine in gender.
