Diagnosis.
A large yellow species (wing length 2.2-2.3 mm) having a shiny yellow scutum with a medial and two pairs of black stripes, a black 1st flagellomere, yellow maxillary palpus, yellow halteres, and yellow legs. Male epandrium inner-laterally with a hypertrophied tubercle-like seta, and inner-basally with a comb comprising three or four long fused tubercle-like setae. Larva mines the thallus of Conocephalum salebrosum , C. orientalis and C. purpureorubrum .
Description.
Adult male.
Head: (Fig. 54A-E View Figure 54 ) Head yellow, with back of head dark brown excluding margins. (Fig. 54C View Figure 54 ). Antenna porrect, first flagellomere black, pedicel and scape yellow (Fig. 54B View Figure 54 ). Arista subbasal, black, pubescent. Clypeus, face, gena, parafacial and postgena yellow. Proboscis normal, yellow; palpus yellow, cylindrical (Fig. 54C View Figure 54 ). Chaetotaxy: Front orbitals three pairs; one ori directed inward; two ors directed upward (Fig. 54B View Figure 54 ). Orbital setulae minute and erect, in a single row.
Thorax: Thorax shiny. Scutum yellow with medial dark stripe on anterior 2/3, with a pair of narrow pale brown supra-alar stripes and a pair of wider black intra-alar stripes, which adjoin a pair of lateral presutural dark ovoid spots (Fig. 54D View Figure 54 ). Scutellum yellow, subscutellum yellow with brown margin. Mediotergite brown, anatergite yellow with small brown spot near lower margin, and katatergite yellow (Fig. 54E View Figure 54 ). Pleuron yellow with brownish patches on venter of katepisternum and meron (Fig. 54B View Figure 54 ). Haltere yellow. Calypter margin and hairs gray. Leg segments entirely yellow; tibia and tarsus darker (Fig. 54A View Figure 54 ). Chaetotaxy: Scutum with 1+3 dorsocentrals, shortened anteriorly. 20-26 acrostichal setulae in four irregular rows (Fig. 54D View Figure 54 ). Wing: Wing length 2.2 mm, costa reaching M1 (Fig. 54A View Figure 54 ). Length of ultimate section of vein M4 divided by penultimate section 1.3.
Abdomen: Abdomen dorsally subshiny yellow; epandrium dark brown (Fig. 54E View Figure 54 ). Genitalia: (Fig. 54G-J View Figure 54 ) Epandrium rounded apically; inner-posterior margin with a dark ridge; inner-lateral surface with a flattened triangular tubercle-like seta; inner-anterior surface with a comb comprising three or four basally fused long tubercle-like setae (rarely unfused in part); inner-lateral margin with a row of three or four small tubercle-like setae (Fig. 54I View Figure 54 ). Surstylus elongated, curved inwards; with a few short setae apically; with one stout tubercle-like seta subapically (Fig. 54I View Figure 54 ). Cercus narrow, setose. Subepandrial sclerite with a pair of plate-like arms, the dorsal lobe of which is dark, hooked toward dorsum (Fig. 54I View Figure 54 ). Hypandrium slightly sclerotized along outer margin (Fig. 54G View Figure 54 ). Postgonite bare, goose barnacle-shaped, rounded apically, cleft subapically (Fig. 54H View Figure 54 ). Phallophorus with deep incision below, articulated with phallapodeme, fused to epiphallus (Fig. 54G View Figure 54 ). Basiphallus with a pale broad, plate-like sclerite on left side (Fig. 54G View Figure 54 ). Hypophallus broad, membranous covered with microtrichia ventrally; lateral margins lightly sclerotized; medially with a pair of fused narrow sclerites (Fig. 54H View Figure 54 ). Paraphallus absent. Mesophallus dark, cylindrical, widest basally, as long as distiphallus (Fig. 54H View Figure 54 ). Distiphallus comprising one pair of stout tubules basally parallel to each other; covered by a membrane bearing 7-9 pairs of minute oval lateral sclerites basal half composed of ventral dark subtriangular sclerite and weaker medial region; distal half cylindrical, dark; constricted subdistally; with truncated unpigmented apex (Fig. 54H View Figure 54 ). Ejaculatory apodeme pale brown, with fan-shaped blade and short stalk; base wide to one side; sperm pump clear (Fig. 54J View Figure 54 ).
Female (Fig. 54F, M View Figure 54 ). Similar to male, but slightly larger and frons wider. Wing length 2.3 mm. Postabdomen: (Fig. 54K, L View Figure 54 ) Oviscape dark brown, setigerous (Fig. 54K View Figure 54 ). Tergite 10 trifurcate, laterally uniting narrow pleural sclerites (Fig. 54L View Figure 54 ). Each cercus with two stout, apical, trichoid sensilla, 1/3 length of cercus (Fig. 54L View Figure 54 ). Spermathecae semi-orbicular, with truncate proximal ends (Fig. 54K View Figure 54 ).
Etymology.
The specific name (bifasciata = two stripes) refers to a pair of black stripes on the yellow scutum.
Japanese name.
Tsuyasuji-jagoke-hamoguribae.
Host plants.
Conocephalum salebrosum and C. orientalis ( Conocephalaceae ).
Mine.
Larvae construct linear mines in the midrib of the thallus, and pupate in the mines (Fig. 54O-Q View Figure 54 ).
Biological notes.
The habitats of this species are stream banks and mesic slopes in cool temperate deciduous forests dominated by Quercus crispula , Fagus crenata and Aesculus turbinata (Fig. 54N View Figure 54 ). It was sympatric with P. izayoi , P. luteola , and P. conocephali at some localities. Our rearing records suggest that this species is univoltine, and that adults emerge from overwintered pupae in spring.
Distribution.
Japan: Hokkaido, Honshu, Shikoku and Kyushu (Fig. 55 View Figure 55 ).
Remarks.
This species resembles P. dorsata , P. calcicola , P. argentifasciata , P. longifurcae , P. brunofasciata , and P. pallidofasciata in having two pairs of dark lateral stripes on the scutum; it is distinguished from all of them by the glossy scutum (subshiny in the other species) and by the dissimilarity of color between the outer and inner pairs of the stripes (color is similar between outer and inner pairs in the other species).
