Hystrichophora loricana (Grote)

Phoxopteris loricana Grote 1880:218 .

Ancylis loricana: Fernald [1902]:468; Barnes and McDunnough 1917:174; Heinrich 1923:253; Forbes 1923:408. Hystricophora [sic] loricana: Heinrich 1929:20 ; McDunnough 1939:52.

Hystrichophora loricana: Powell 1983:37 ; Brown et al. 2005:391; Gilligan et al. 2008:168.

Type. Holotype: 3, “630; Grapholitha taleana Grote Type.; Fernald Collection,” [Dayton, Ohio, G. R. Pilate], “male genitalia slide, 19 June 1925, C. H. #17” [slide is lost], deposited in the USNM.

Diagnosis. Hystrichophora loricana can be recognized by the projecting apex, prominent orange markings, and strong metallic reflections of the forewing. Forewing pattern is similar to H. taleana and two undescribed species near taleana (Gilligan, unpublished); however, these species lack the projecting apex and metallic reflections of the forewing.

Redescription. Head: Frons and vertex bronze; labial palpus with lateral surface concolorous with head, medial surface lighter, second segment as long as head; antenna length 0.6 X forewing length, antenna and scapus concolorous with head. Thorax: Tegulae and mesonotum concolorous with head; legs concolorous with mesonotum, tarsomeres ringed with lighter scales distally. Forewing ( Figs. 1–2 ): FWL 7.0– 8.5 mm (mean = 7.8 mm, n = 6); costal margin slightly curved from base to apex; apex strongly projecting; termen concave between veins R5 and CU1; wing bronze from base to median fascia with a longitudinal patch of dark-brown white-tipped scales anterior to ocellus and extending basally into median area and posteriorly along proximal margin of ocellus; costal strigulae pairs 9 and 10 clearly visible; preterminal fascia pale orange, extending from costa at R3 towards termen, not reaching R4; postmedian fascia orange, extending from costa at R1 to the termen, dislocated along M3; median fascia orange, present as a small patch on the costa at Sc; ocellus consisting of remnants of preterminal, postmedian, and median fasciae; preterminal remnant a longitudinal row of black scales with surrounding pale orange extending to termen; postmedial remnant with two short longitudinal rows of black scales bordered anteriorly by pale orange; median remnant a small patch of black scales bordered anteriorly and posteriorly with pale orange; tornus and central field of ocellus bronze; striae silvery bronze; stria arising from strigulae pair 7 running the length of the postmedian fascia; fringe bronze, scales becoming darker near the apex. Hindwing: Ground color dark grayish brown, fringe scales lighter. Abdomen ( Fig. 4 ): Eighth abdominal sternite modified to form two finger-like projections, one with length 1.25 X that of the other; tergite of eighth abdominal segment asymmetrical and excavate medially, forming two strongly sclerotized distal projections with numerous short spines. Male Genitalia ( Fig. 5 ): Uncus well developed, elongate, asymmetrically bifid, with distal projections strongly sclerotized; socii and gnathos absent; tegumen broad, asymmetrical, with anterior margin sinuate; aedeagus curving ventrally, vesica with three rows of about 25 cornuti (n = 1), distal three cornuti stout, 2 X length of others; valvae asymmetrical, divided into costal and saccular lobes; costal lobe long and slender, the apex forming a densely setose club; left saccular lobe broad, ventral margin with a row of short setae, apex rounded with numerous short setae, sacculus a poorly defined rounded ridge; right saccular lobe elongate with a patch of stout setae arising ventromedially and extending distally, distal end with numerous short setae, sacculus a poorly defined rounded ridge. Female genitalia ( Fig. 6 ): Papillae anales broad, densely setose, lateral margins with row of longer setae; tergum VIII with numerous setae on ventrolateral surface, dorsoanterior surface strongly sclerotized and microspinulate, anterior margin poorly defined between the apophyses anteriores; apophyses anteriores thin, with length approximately 0.75 X that of abdominal segment VII and equal in length with apophyses posteriories; ostium bursae located medially on genital plate, asymmetrical, membranous, circular; posterior margin of sternum VII invaginated to entire length of sterigma, strongly sclerotized, fused with lamella postvaginalis and lamella antevaginalis; lamella postvaginalis a sclerotized ridge; lamella antevaginalis forming a channel extending anteriorly from ostium to a strongly sclerotized pocket on the anterior margin of sternum VII; ductus bursae membranous, arising posteriolaterally from ostium; corpus bursae large, oval, membranous covered with short, blunt, rounded projections, two signa blade or finlike and of equal size.

Material Examined. We examined the holotype male and six specimens (5 3, 1 Ƥ) from the following locations: KENTUCKY: Lincoln Co., near Stanford, L. D. Gibson, 28 August 2008 (1 3, genitalia slide TMG455; 1 Ƥ, genitalia slide TMG456). ILLINOIS: Coles Co., Charleston Lake View Park, N 39o 28.309' W 0 88 o 09.000', T. Harrison, 19 August 1990 (1 3), 16 August 2008 (1 3), 21 August 2008 (1 3); Coles County, Charleston, T12N, R9E, NW 1/4 Sec. 11, T. Harrison, 7 August 1996 (1 3, genitalia dissection, wing slide M. Sabourin).
