Mirandofures kamena Gustafsson & Bush  , new species

( Figs 90–97View FIGURES 90 – 91View FIGURES 92 – 97)

Type host. Erythrura trichroa sigillifer (De Vis, 1897)  —blue-faced parrotfinch. Type locality. Mount Kaindi , elev. 2300 m, Morobe District, Papua New Guinea. 

Diagnosis. Females are separated from all other described species in the genus by the lack of a median extension of the subgenital plate ( Fig. 97View FIGURES 92 – 97) and the set of large setae on the posterior margin of the subgenital plate. Male genitalia ( Figs 94–96View FIGURES 92 – 97) similar to those of Mirandofures amandavae  , but the parameres of Mirandofures kamena  n. sp. are larger, more elongate, and more strongly curved. The mesosome of Mi. kamena  is longer and broader with more extensive mesosomal lobes and more prominent lateral nodi of the gonopore in Mi. kamena  than in Mi. amandavae  .

The head shape ( Fig. 92View FIGURES 92 – 97) and male genitalia ( Figs 94–96View FIGURES 92 – 97) of Mi. kamena  are similar to those of Mi. stenozona  . However, the preantennal area of Mi. kamena  is proportionally longer and more narrow anteriorly than is the case in Mi. stenozona  , and the marginal carinal plate is not as extensive in Mi. stenozona  as in Mi. kamena  . In both species, the proximal mesosome is roughly rectangular, the parameres are slender and elongated, and there is no distinct heel of the paramere distal to the mesosome. However, the mesosomal lobes of Mi. kamena  are broad and rounded with rugose area limited to distal margin, whereas in Mi. stenozona  the lobes are slender, somewhat angular distally, and with the rugose areas extending along the entire lateral margins. Female Mi. kamena  are separated from female Mi. stenozona  by the fact that in the former species the subgenital plate does not extend posteriorly towards the vulval margin, whereas in the latter species a broad median section of the subgenital plate reaches the vulval margin. The long setae at the posterior margin of the subgenital plate in Mi. kamena  ( Fig. 97View FIGURES 92 – 97) are absent in Mi. stenozona  .

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus description and Fig. 92View FIGURES 92 – 97. Marginal carinal plate extensive, obovate. Marginal temporal carina, postmarginal carina, and head nodi with dark brown pigmentation. Thoracic and abdominal segments as in genus description and Figs 90–91View FIGURES 90 – 91. Pleural ridge prominent, swollen. Pleural incrassations with large median extensions in anterior end, especially prominent in females. Sternal plates and median section of tergopleurites translucent in both sexes, but pleurites and lateral sections of tergopleurites medium to dark brown, lighter brown in area around spiracle openings.

Male. Antennae as in Fig. 92View FIGURES 92 – 97. Abdominal chaetotaxy as in Table 4 and Fig. 90View FIGURES 90 – 91; ss of tergopleurites III –IV often absent. Basal apodeme with constriction at mid-length ( Fig. 94View FIGURES 92 – 97). Proximal mesosome trapezoidal, rounded. Gonopore ( Fig. 95View FIGURES 92 – 97) narrowly open distally. Mesosomal lobes rounded, small, with rugose distal ends. Small submedian spur on each lobe; 3 pmes sensilla sublaterally on each lobe. Parameral heads ( Fig. 96View FIGURES 92 – 97) bifid. Parameral blades gently curved around mesosome, distally elongate, slender; pst1–2 as in genus description. Measurements ex Erythrura trichroa sigillifer  (n = 13, except n = 10 for TL and n = 12 for AW): TL = 1.41–1.57 (1.48); HL = 0.33–0.39 (0.36); HW = 0.24–0.26 (0.25); PRW = 0.16–0.20 (0.18); PTW = 0.23–0.28 (0.26); AW = 0.36–0.44 (0.39).

Female. Antennae as in Fig. 93View FIGURES 92 – 97. Abdominal chaetotaxy as in Table 4 and Fig. 91View FIGURES 90 – 91. Subgenital plate rounded rectangular ( Fig. 97View FIGURES 92 – 97), not modified compared to other sternal plates; distal margin not or only slightly bulging medianly, not approaching vulval margin. Vulval margin gently rounded, not bulging medianly ( Fig. 97View FIGURES 92 – 97), with 4–6 slender vms on each side, and 4–6 short, thorn-like vss on each side. One long, slender setae median to vss on each side; 2–3 long setae on posterior margin of subgenital plate on each side, and 3–5 shorter, slender vos scattered posterior to subgenital plate on each side. Measurements ex Erythrura trichroa sigillifer  (n = 15 except n = 14 for TL and n = 13 for AW): TL = 1.89–2.08 (1.99); HL = 0.40–0.42 (0.41); HW = 0.27–0.29 (0.28); PRW = 0.19–0.21 (0.20); PTW = 0.25–0.30 (0.29); AW = 0.36–0.59 (0.44).

Etymology. The species epithet “ kamena  ” is derived from the Greek “ kaména  ”, meaning burned or charred, and referring to the darkened pleurites, perhaps particularly the darkened median margin of the hook-shaped pleural heads, which looks as though they have been touched by flames.
