Type host. Dicrurus bracteatus carbonarius Bonaparte, 1850 —spangled drongo.

Type locality. Embi Lakes , Popondetta, Northern Province, Papua New Guinea .

Diagnosis. Guimaraesiella (Di.) carbonivora is morphologically closest to Guimaraesiella (Di.) latitemporalis n. sp. (see below), but they can be separated by the following male genitalic characters: (1) proximal margin of mesosome concave in Guimaraesiella (Di.) carbonivora , but straight in Guimaraesiella (Di.) latitemporalis ; (2) ventral sclerite reaches anterior margin of mesosome in Guimaraesiella (Di.) latitemporalis , but not in Guimaraesiella (Di.) carbonivora ; (3) additional ventral sclerite short and pointed anteriorly in Guimaraesiella (Di.) carbonivora , but long with irregular anterior end in Guimaraesiella (Di.) latitemporalis ; (4) rugose area of mesosomal lobes restricted to sublateral bulges in Guimaraesiella (Di.) carbonivora , but forming medianly continuous arch in Guimaraesiella (Di.) latitemporalis ( Figs 19 , 26 ). Also, these two species differ by aps being absent on male tergopleurites IV–V and female tergopleurite VIII in Guimaraesiella (Di.) carbonivora ( Figs 15–16 ), but present on these tergopleurites in Guimaraesiella (Di.) latitemporalis ( Figs 22–23 ).

Description. Both sexes. Head and chaetotaxy as in Fig. 17 , with lateral margins of preantennal area slightly convex, frons broadly flattened; marginal carina irregular, broad but narrowing considerably anteriorly; dorsal preantennal suture reaches dsms and ads, nears but does not reach lateral margins of head; ventral anterior plate semicircular; coni long, slender; temples rounded; gular plate pentagonal, pointed anteriorly ( Fig. 17 ). Thoracic and abdominal segments as in Figs 15–16 .

Male. Thoracic and abdominal chaetotaxy as in Fig.15 ; aps absent on tergopleurites IV–V, but present on tergopleurites VI–VII. Genitalia as in Figs 18–20 : basal apodeme rectangular with rounded anterior end, not constricted laterally ( Fig. 18 ). Proximal mesosome about as broad as distal mesosome, with concave anterior margin; ventral sclerite with irregular lateral margins, not reaching anterior margin of mesosome; mesosomal lobes broad, with sinuous lateral margins; rugose nodi slight; 2 ames sensilla on each side near antero-lateral corners of mesosomal lobes; 2 pmes sensilla on each side of gonopore, near rugose nodi; gonopore roughly circular, with slender marginal thickenings ( Fig. 19 ). Parameral heads rectangular ( Fig. 20 ). Parameral blades slightly curved, broad, tapering only distally ( Figs 18, 20 ). Measurements: Ex Dicrurus bracteatus carbonarius (n = 33, except TL and AW, where n = 30): TL = 1.17–1.45 (1.32); HL = 0.33–0.39 (0.36); HW = 0.28–0.36 (0.32); PRW = 0.18–1.22 (0.20); PTW = 0.26–0.32 (0.29); AW = 0.35–0.47 (0.40).

Female. Thoracic and abdominal chaetotaxy as in Fig. 16 ; psps absent on tergopleurite VIII. Subgenital plate broadly rectangular anteriorly; lateral submarginal bulges small. Vulval margin bulging distinctly medianly, with 3–4 long, slender vms on each side, and 4–7 short, thorn-like vss on each side; 3–6 long, slender vos on each side; distal 1 vos anterior to vss ( Fig. 21 ). Measurements: Ex Dicrurus bracteatus carbonarius (n = 44, except TL and PRW where n = 43, and AW where n = 39): TL = 1.38–1.67 (1.56); HL = 0.36–0.42 (0.39); HW = 0.32–0.38 (0.35); PRW = 0.18–0.23 (0.21); PTW = 0.28–0.34 (0.32); AW = 0.40–0.51 (0.45).

Etymology. The species epithet derives from “ carbo ” Latin for “coal”, and “ vorare ” Latin for “to devour”, referring to the name and dark plumage of the host subspecies.
