Coracina caeruleogrisea strenua (Schlegel, 1871) – stout-billed cuckooshrike. Type locality. Mount Bosavi , Southern Highlands Province , Papua New Guinea . Diagnosis. Shape of the proximal mesosome and mesosomal lobes suggest a close relationship between In. ( In. ) microgenitalis new species ( Figs 4–6 ) and In. ( In. ) saburrata new species ( Figs 11–13 ). These two species can be separated by the following characters: proximal mesosome with slight lateral bulges in In. ( In. ) microgenitalis ( Fig. 5 ), but without such bulges in In. ( In. ) saburrata ( Fig. 12 ); female subgenital plate gently rounded distally in In. ( In. ) microgenitalis ( Fig. 7 ), but broadly flattened distally in In. ( In. ) saburrata ( Fig. 14 ); shape of dorsal fringe and distal margin of mesosome differ between species ( Figs 4–5 ; 11–12 ); male tergopleurite V with 2 ss and male tergopleurites VI–VII with>2 ss on each side in In. ( In. ) microgenitalis ( Fig. 1 ), but tergopleurite V with 1 ss and tergopleurites VI–VII with 2 ss on each side in In. ( In. ) saburrata ( Fig. 8 ); abdominal segment VI in both sexes with 3 ps on each side in In. ( In. ) microgenitalis ( Figs 1–2 ), but with 2 ps on each side in In. ( In. ) saburrata ( Figs 8–9 ); lateral margins of preantennal head more convex in In. ( In. ) microgenitalis ( Fig. 3 ) than in In. ( In. ) saburrata ( Fig. 10 ). Description. Both sexes . Head rounded trapezoidal ( Fig. 3 ), lateral margins of preantennal head convex, frons slightly concave. Marginal carina broad, narrowing conspicuously near dsms , deeply displaced and widened at osculum. Ventral anterior plate slender, crescent-shaped. Head chaetotaxy as in Fig. 3 . Preantennal nodi large, bulging. Pre- and post-ocular nodi large, connected dorsally by broad ocular band. Marginal temporal carina slender. Gular plate triangular, tapering anteriorly. Thoracic and abdominal segments as in Figs 1–2 . Base pigmentation translucent; preantennal and preocular nodi dark brown; posterior section of marginal carina, margins of antennal sockets, parts of mandibular framework, ocular band, postocular nodi, gular plate, proepimera, metepisterna, medium brown; sternal plates II–VI and subgenital plates pale brown, anterior sternal plates paler than posterior plates. Male. Thoracic and abdominal chaetotaxy as in Fig. 1 ; tergopleurite V with 2 ss on each side; tergopleurites VI–VII with 3–4 ss on each side; segment VI with 3 ps on each side. Basal apodeme roundly broadened anteriorly ( Fig. 4 ). Proximal mesosome with lateral bulges but not marked extensions ( Fig. 5 ), and anterior margin convex. Mesosomal lobes more or less parallel. Distal margin of mesosome deeply concave. Gonopore with antero-lateral extensions slightly hooked. Dorsal fringe not tilted posteriorly, with small rounded thumb-like process on anterior margin. Chaetotaxy: 2 ventral gpmes sensilla on each side of distal gonopore; lpmes not visible in single examined male; 1 dorsal ames sensilla on each side distal to dorsal fringe. Parameres and pst1–2 as in Fig. 6 . Measurements as in Table 1 . Female. Thoracic and abdominal chaetotaxy as in Fig. 2 ; segment VI with 3 ps on each side. Subgenital plate with broadly rounded distal margin ( Fig. 7 ). Vulval margin flattened medianly, with 2 short, slender vms and 1 short, thorn-like vss on each side; 4–6 slender vos on each side of subgenital plate; distal 2–3 vos median to vss , and markedly longer than vms . Measurements as in Table 1 . Etymology. The species epithet is derived from Greek “ micros ” for “small” and Latin “ genitalis ” for “genitalia”, referring to the relatively small male genitalia of this species. Type material.
