Parasaphodes townsendi (Ashmead)

( Figs 155–166 View FIGURES 155 – 158 View FIGURES 159 – 166 )

Parasaphes townsendi Ashmead, 1905: 404 ; syntypes in USNM, examined.

Parasaphodes townsendi ( Ashmead, 1905) ; new combination by Bouček 1988: 346.

Diagnosis. Both sexes: clypeal margin subtruncate; genae long and not strongly converging towards mouth ( Fig. 159 View FIGURES 159 – 166 ); scape short, not nearly reaching lower margin of median ocellus ( Fig. 159 View FIGURES 159 – 166 ); anterior corners of pronotal collar carinate ( Fig. 160 View FIGURES 159 – 166 ); axillae strongly advanced ( Fig. 163 View FIGURES 159 – 166 ); propodeum with median carina defined only anteriorly, splitting in two in the middle of propodeum, median area with several additional interconnected carinae, the interspaces smooth ( Fig. 165 View FIGURES 159 – 166 ); gaster virtually sessile, petiole small, strongly transverse, with two lateral flanges and some longitudinal rugae on dorsal side ( Fig. 165 View FIGURES 159 – 166 ).

Female: funicular segments long ( Fig. 162 View FIGURES 159 – 166 ), F1 length 1.4–1.6× width, F7 length 1.3–1.6× width.

Male: F1 length about 2.8× width.

Parasaphodes townsendi is very similar to P. iceryae (see the remarks on the latter species).

Redescription. Female. Body length: 0.9–1.1 mm.

Colour. Head blackish-brown, with faint metallic reflections ( Figs 159–161 View FIGURES 159 – 166 ). Mesosoma brown ( Figs 163–165 View FIGURES 159 – 166 ). Gaster light brown basally, becoming darker towards apex ( Figs 155, 157 View FIGURES 155 – 158 ). Eyes red; ocelli pale orange ( Figs 159, 160 View FIGURES 159 – 166 ). Antenna ( Fig. 162 View FIGURES 159 – 166 ) with scape, pedicel and proximal flagellar segments yellowish-brown, flagellum becoming darker distally. Legs yellowish-brown, except for brown fore coxae and pretarsi ( Fig. 155 View FIGURES 155 – 158 ). Wings hyaline, tegula and venation light brown ( Fig. 166 View FIGURES 159 – 166 ). Body pilosity whitish, wing pilosity pale brown ( Figs 163, 166 View FIGURES 159 – 166 ).

Sculpture. Head smooth ( Figs 159–161 View FIGURES 159 – 166 ). Mesosoma with pronotum and mesoscutum smooth to finely coriaceous; axillae and mesoscutellum smooth ( Figs 163, 164 View FIGURES 159 – 166 ); propodeum variable, but usually with median carina defined only anteriorly, splitting in two in the middle of propodeum, and median area with several additional interconnected carinae, the interspaces smooth ( Fig. 165 View FIGURES 159 – 166 ); prepectus and metapleuron smooth; almost entire mesopleuron alutaceous ( Fig. 164 View FIGURES 159 – 166 ). Gaster smooth.

Structure. Head. Clypeal margin subtruncate. Genae short and strongly converging towards mouth ( Fig. 159 View FIGURES 159 – 166 ). Scape short, not nearly reaching lower margin of median ocellus ( Fig. 159 View FIGURES 159 – 166 ). Head width 2.1–2.2× length in dorsal view (38:17) and about 1.3× height in frontal view (38:29). POL 1.0–1.1× OOL (8:7). Eye height 1.2× length (17:14) and 1.5× malar space (17:11). Scape length about half eye height (9:17) and 1.3–1.6× length of pedicel (9.0:5.5). Head width 0.6–0.7× length of pedicel plus flagellum. F1 width 1.4–1.6× length; F5 width 1.3–1.6× length; clava length 2.8–3.2× width.

Mesosoma. Anterior corners of pronotal collar carinate ( Fig. 160 View FIGURES 159 – 166 ). Axillae strongly advanced ( Fig. 163 View FIGURES 159 – 166 ). Mesosoma length 1.3–1.4× width (46:33), width about 0.9× height (33:35). Mesoscutum width about 1.9× length (33:17). Mesoscutellum length about equal to width (19:19). Propodeum length about half mesoscutellum length (10:19). Dorsellum about 0.3× propodeum length (3:10). Fore wing length about 2.4× width (90:38). MV length 5.4–6.5× SV (26:4); MV 5.2–5.4× PV (26:5).

Metasoma. Petiole small, strongly transverse, with two lateral flanges and some longitudinal rugae on dorsal side ( Fig. 165 View FIGURES 159 – 166 ). Gaster ( Figs 155, 157 View FIGURES 155 – 158 ) short ovate in dorsal view, length 1.9–2.1× width (45:21) and shorter than to subequal in length to mesosoma, with apex sometimes more or less truncated due to retraction of tergites; hypopygium more or less exserted, tip upturned.

Male. Similar to female, but differs mainly as follows. Body length: 0.7–0.8 mm. Flagellar segments longer and thinner. F1 length about 2.8× width. Gaster length 1.1–1.2× width, posterior part truncated due to strong retraction of tergites ( Fig. 156 View FIGURES 155 – 158 ).

Distribution. Philippines ( Ashmead 1905); Malaysia (new record).

Biology. According to Ashmead (1905), the specimens were reared “from a coccid” (p. 405). Bouček (1988) stated that the species was reared from Icerya purchasi Maskell and I. seychellarum (Westwood) , without giving any references. As the above label records show, P. townsendi was reared from I. aegyptiaca (Douglas) and I. seychellarum , without any mention of I. purchasi , which can be regarded as a doubtful record.

Remarks. In 1984 Z. Bouček labelled a female as lectotype ( Figs 155, 157, 158 View FIGURES 155 – 158 ), but the designation was not formally published; this is done in the present revision. According to Ashmead (1905), the species was described “from 5 female and 3 male specimens” (p. 405). From the collection of USNM I examined one female (designated as lectotype) and two males (paralectotypes, Fig. 156 View FIGURES 155 – 158 ); an additional female from the same type series is missing from the point. An additional two females (one with both antennae broken, the other without head) bearing the same labels as the type material, except for a type label, were listed as “other material”. For additional comments see P. iceryae .
