Anarchonirmus albovittatus Gustafsson & Bush , new species

( Figs 114–121 )

Type host. Pomatostomus temporalis strepitans (Mayr & Rand, 1935) — gray-crowned babbler. Type locality. Weam (elev. 40 ft), Western District, Papua New Guinea.

Diagnosis. As mentioned above, Anarchonirmus n. gen. displays a conglomerate of morphological characters that makes it difficult to establish what other genus of the Brueelia -complex it is most closely related to. Male genitalia and other characters suggest relationships with Brueelia s. str., Sychraella n. gen., Hecatrishula n. gen., and Osculonirmus . Anarchonirmus ( Figs 114–121 ) can be separated from Brueelia s. str. ( Figs 42–48 ), Sychraella ( Figs 106–113 ), Osculonirmus ( Figs 122–129 ) and Hecatrishula ( Figs 130–137 ) by the following characters: in these four genera the clypeo-labral suture reaches the anterior end of head, and the marginal carina is displaced dorsally at the osculum, but this is not the case in Anarchonirmus ( Fig. 116 ); sternal plates and the anterior end of the subgenital plate of both sexes have no special modification in either of these four genera, but antero-lateral corners are densely sclerotized into nodi in Anarchonirmus ( Figs 114–115 ); ventral anterior plate, if present, is separate from marginal carina in the four genera, but fused to the carina in Anarchonirmus ( Fig. 116 ).

Description. Both sexes. Head shape, cheatotaxy, and preantennal structure as in genus description and Fig. 116 . Preocular nodi large, postocular nodi not wider than marginal temporal carina. Head largely translucent, but marginal, ventral, and occipital carinae, margins of antennal socket, mouth parts, gular plate and bands on antennae pigmented brown. Thoracic and abdominal segments and chaetotaxy as in genus description and Figs 114–115 ; psps long. Only anterior, posterior, and lateral margins of tergopleurites pigmented. Sternal plates short but broad, approaching lateral margins of abdomen. Pigmentation of sternal plates distinctive, with anterior and posterior margins light brown, and middle section translucent. Pigmentation of sternal plates more extensive in females than in males. Lateral ends of anterior pigmentation more intensely pigmented in segments II–VII, giving the impression of large brown spots.

Male. Preantennal nodi slender ( Fig. 116 ). Scape ( Fig. 116 ) almost 3 times as thick and twice as long as female scape ( Fig. 117 ), and more distal antennal segments swollen in males. Pedicle pigmented brown. Pteronotum with 7 mms macrosetae on each side. Abdominal chaetotaxy as in Table 2 and Fig. 114 ; 5–7 tps on segments VII–VIII. Lateral bulges of subgenital plate as intensely pigmented as sternal plates, shaped as in Fig. 114 . Basal apodeme ( Fig. 118 ) broad, somewhat constricted at mid-length, with pointed proximal end. Lateral thickenings slender, but broadens markedly in proximal end, and are medianly continuous anteriorly. Distal margin of basal apodeme deeply concave. Proximal mesosome small, bluntly trapezoidal, with slight distal lateral thickening that appear continuous with small, slender, distally open gonopore. Mesosomal lobes ( Fig. 119 ) uniquely shaped within Brueelia -complex, extending proximally to reach concave distal margin of the basal apodeme. Distally, lobes are moderate, with serrated or pectinate distal margins, and large rugose areas that cover more or less all of the lobes distal to gonopore. Parameral heads ( Fig. 120 ) broad, cup-shaped, interlocking with the lateral distal ends of the basal apodeme. Parameral blades curve around mesosomal lobes, forming a small heel medianly just distal to lobes. Distal part of blades much elongated; pst1 not visible; pst2 microseta, lateral near distal tip. Measurements ex Pomatostomus temporalis (n = 5): TL = 1.09–1.18; HL = 0.28–0.30; HW = 0.33–0.35; PRW = 0.19–0.22; PTW = 0.32–0.35; AW = 0.44–0.49.

Female. Preantennal nodi rounded ( Fig. 115 ). Pedicel and flagellomeres pigmented brown. Pteronotum with 5 mms macrosetae on each side. Abdominal chaetotaxy as in Table 2 and Fig. 115 . Female subgenital plate ( Fig. 121 ) intensely pigmented in antero-lateral corners. Vulval margin ( Fig. 121 ) with 4–6 slender vms on each side, and 5–6 thorn-like vss on each side; 4–7 slender vos on each side; distal seta much separated from proximal setae and much shorter. Gonapophyse with 1 stout seta, and 1 microseta on each side. Measurements ex Pomatostomus temporalis (n = 11): TL = 1.42–1.61 (1.48); HL = 0.31–0.35 (0.32); HW = 0.35–0.39 (0.37); PRW = 0.19–0.23 (0.21); PTW = 0.34–0.38 (0.36); AW = 0.46–0.53 (0.49).

Etymology. The species epithet is formed by Latin “ album ” for “white” and “ vitta ” for “ribbon”, referring to the broad, translucent bands across the tergopleurites and sternal plates.
