Harpactrox geminodus Gustafsson & Bush , new species
( Figs 253 View FIGURES 253 – 254 –259)
Type host. Harpactes erythrocephalus erythrocephalus (Gould, 1834) — red-headed trogon. Type locality. Chiang Saen Kao , Chiang Rai Province, Thailand.
Diagnosis. Harpactrox geminodus n. sp. is separated from the two other species in the genus by head shape; the head is proportionately narrower in Ha. geminodus (Fig. 255) than in either Ha. loeiensis n. sp. ( Fig. 248 View FIGURES 248 – 252 ) or Ha. pontifrons n. sp. ( Fig. 260 View FIGURES 260 – 262 ). As in Ha. loeiensis ( Fig. 248 View FIGURES 248 – 252 ) the dorsal preantennal suture extends anteriorly from the ads in Ha. geminodus (Fig. 255), but only in Ha. geminodus does it reach the dsms; the dorsal preantennal suture does not extend anteriorlyin Ha. pontifrons ( Fig. 260 View FIGURES 260 – 262 ). The proximal mesomere of Ha. geminodus (Fig. 257) is FIBURES 255–259. Harpactrox geminodus n. gen. & n. sp. ex Harpactes erythrocephalus erythrocephalus : 255 male head, dorsal and ventral views. 256, male genitalia, dorsal view. 257, male mesosome, ventral view. 258, male paramere, dorsal view. 259, female subgenital plate and vulval margin.
broad and flattened, whereas that of Ha. loeiensis ( Fig. 250 View FIGURES 248 – 252 ) is narrow and rounded. Vulval chaetotaxy of Ha. geminodus intermediate between that of the other two species, and female best identified on non-genitalic characters.
Description. Both sexes. Head shape, structure, and chaetotaxy as in Fig. 255. Ventral anterior plate much wider than marginal carina. Ventral carinae clearly defined anterior to pulvinus. Dorsal preantennal suture reaches ads and dsms. Preantennal nodi large. All mts of about equal length, except mts 3 about twice as long as other mts . Gular plate spade-shaped. Thoracic and abdominal segments as in genus description and Figs 253–254 View FIGURES 253 – 254 . Sternal plates and subgenital plates very pale, and illustrated only tentatively.
Male. Subgenital plate sinuously trapezoidal ( Fig. 253 View FIGURES 253 – 254 ). Abdominal chaetotaxy as in Table 2 and Fig. 253 View FIGURES 253 – 254 ; 1 tps present on tergopleurite VIII in one examined male, absent in the other. Basal apodeme broad (Fig. 256). Proximal mesosome broad, anterior margin roughly flat. Gonopore (Fig. 257) terminal, not extended distally. Mesosomal lobes angular; 3 ames microsetae submedianly on each side anterior to gonopore; 2 pmes microsetae laterally to gonopore on each side. Parameral heads rounded rectangular. Parameral blades (Fig. 258) blunt, slender; pst1–2 as in genus decsription. Measurements ex Harpactes erythrocephalus erythrocephalus (n = 2, TL and AW cannot be measured due to mounting): HL = 0.35–0.37; HW = 0.36–0.39; PRW = 0.23–0.24; PTW = 0.36–0.39.
Female. Abdominal chaetotaxy as in Table 2 and Fig. 254 View FIGURES 253 – 254 . Subgenital plate sinuously trapezoidal, reaching vulval margin (Fig. 259). Vulval margin (Fig. 259) somewhat angular, with 2 short, slender vms on each side, and 3–5 short, thorn-like vss on each side; 5–7 long, slender vos; the 2–3 distal vos median to vss. Measurements ex Harpactes erythrocephalus erythrocephalus (n = 3): TL = 1.86–2.01; HL = 0.40–0.41; HW = 0.44–0.45; PRW = 0.26–0.27; PTW = 0.41–0.42; AW = 0.59–0.68.
Etymology. The species epithet is derived from Latin “ gemini ” for “twins” and “ nodus ” for “ knot ”.
Type material. Ex Harpactes erythrocephalus erythrocephalus : Holotype ♂, Chiang Saen Kao , Chiang Rai Province, Thailand, 4 Mar. 1953, R.E. Elbel, RE-2348, B-14848 ( NHML) . Paratypes: 1♀ same data as holotype ( NHML) ; 1♂, 2♀, same data as holotype (PIPeR).
