description: 3. Anopheles sineroides S. Yamada
(Fig. 2 A, B, 3C, 4C, 5C, 6C)
Size: Length 528.25–584.94 um (mean 553.93 + 24.22 um, n = 7); width 70.12–140.16 (mean 96.71 + 27.16 um, n = 5) (Table 1, Fig. 2 A, B). Color: Black. Overall appearance: Slightly boat-shaped in both ventral and dorsal views, anterior and posterior ends blunt, sometimes slightly pointed. Ventral surface slightly concave, dorsal surface curved, float relatively long and wide in dorso-ventral plane, length 367.40–424.75 um (mean 401.20 + 22.83 um, n = 5); width 59.20–100.10 um (mean 73.97 + 16.21 um, n = 5). Dorsal and lateral surfaces: All surfaces uniformly covered with mostly pentagonal and hexagonal outer chorionic cells or plastron-type cells. (Fig. 3 C), each longer than wide, long dimension oriented in long axis of egg. Interior of each cell with perforated meshwork, surrounded by an elevated, palisade-like outer chorionic reticulum. Cell area 78.84–330.18 um (mean 202.88 + 69.07, n = 20) (Table 1). Float fairly long, about 0.72 length of egg; ratio of float length and width, and length in proportion to egg length and number of ribs as in Table 1. Ribs towards both ends of float wider than those at middle part, slightly striated on dorsal sides; number of ribs per float 28–36 (mean 28.56 + 3.00, n = 9). Ventral surface. Deck continuous, slightly narrows at both ends of float, degree of narrowing usually variable; anterior part of deck usually as wide as posterior part; entire deck covered uniformly with fine tubercles (Fig. 4 C). Frill continuous, shallow along narrowed portion of deck. Lobed ventral tubercles at anterior end of the deck, 5–6 (mean 5.50 + 0.71, n = 2), and at posterior end, 3–4 (mean 3.60 + 0.55, n = 5), (Table 1, Fig. 5 C). Lobed ventral tubercles usually round, occasionally oval or oblong. Lobes of each anterior ventral tubercle, 5–7 (mean 6.50 + 0.84, n = 6); lobes of each posterior ventral tubercle, 6–7 (mean 6.33 + 0.58, n = 3). Lobes clearly separated, often swollen at ends, outer walls often smooth. Lobes in slightly elevated, tuberculoid structures. Anterior end, micropyle. Anterior end slightly more blunt than posterior end. Micropylar collar irregular in outline, with smooth surface, inner edge uniformly and deeply excavated, peaks between excavations tapering to form radial ridges extending about half way across micropylar disc, dividing disc into sectors (Fig. 6 C). Number of sectors (or ridges) 6–7 (mean 6.60 + 0.55, n = 5). Area of micropylar 60.35–90.67 um (mean 80.01 + 17.04 um, n = 3), usually with smooth surface, or covered with thin film.
