Indoceoplanetes (Indoceoplanetes) indonesiana ( Eichler, 1947)

( Figs 217–223 )

Brueelia indonesiana Eichler, 1947: 8 .

Type host. Coracina striata sumatrensis (Müller, 1843) — bar-bellied cuckoo-shrike. Type locality. Laboran [?], Sumatra, Indonesia.

Other hosts. Coracina striata panayensis (Steere, 1890) — bar-bellied cuckoo-shrike new host record. Coracina striata difficilis (Hartert, 1895) —bar-bellied cukoo-shrike new host record.

Description. Both sexes. Head shape, structure, and chaetotaxy as in genus and subgenus descriptions and as in Fig. 219 . Marginal carina widened into marginal carinal plate at osculum. Ventral carinae diffuse anterior to pulvinus. Pre-and postocular nodi connected both dorsally and ventrally. Gular plate bluntly triangular. Head almost entirely translucent, but preantennal, pre-, and postocular nodi, parts of mandibular framework, and gular plate medium brown. Posterior half of marginal carina and at least pedicel and flagellomeres 1–2 pale brown. Thoracic and abdominal segments as in genus and subgenus descriptions and Figs 217–218 . Proepimera, metepisterna, and sternal plates pale to medium brown, the rest of body more or less translucent. Pigmentation typically stronger in females than in males.

Male. Sternal plates IV–VI and subgenital plate with medium brown pigmentation, sternal plate III sometimes with very pale brown pigmentation. Abdominal chaetotaxy as in Table 2 and Fig. 217 . Genitalia as in Figs 220– 222 . Basal apodeme slender. Proximal mesosome widely rounded. Gonopore ( Fig. 221 ) as thick, convergent sclerites, open distally and proximally. Mesosomal lobes wide, overlapping partially with parameres dorsally. Distal margin of lobes papillate, with 2 pmes microsetae on each side submedianly; these setae are often very hard to see. Parameral heads ( Fig. 222 ) pointed. Parameral blades slender blunt; pst1 sensillus; pst2 microseta, lateral near distal tip. Measurements ex Coracina striata sumatrensis (n = 1): TL = 1.51; HL = 0.40; HW = 0.36; PRW = 0.21; PTW = 0.32; AW = 0.45. Ex C. s. difficilis (n = 4): TL = 1.54–1.69; HL = 0.41–0.42; HW = 0.37–0.40; PRW = 0.23–0.24; PTW = 0.31–0.36; AW = 0.44–0.50.

Female. Sternal plates IV–VI and subgenital plate with medium brown pigmentation, sternal plate III with pale brown pigmentation, darker than in male. Abdominal chaetotaxy as in Table 2 and Fig. 218 . Subgenital plate broadly pentagonal, but distal margin flat, not reaching vulval margin ( Fig. 223 ). Vulval margin gently rounded ( Fig. 223 ), with 2 (rarely 3) minute vms on each side, and 0–1 thorn-like vss on each side; 5–6 long, slender vos; distal 2–3 vos distal to vss. Measurements ex Coracina striata panayensis (n = 1): TL = 2.02; HL = 0.45; HW = 0.44; PRW = 0.27; PTW = 0.42; AW = 0.56. Ex C. s. difficilis (n = 4): TL = 1.89–1.95; HL = 0.42–0.44; HW = 0.38–0.42; PRW = 0.24–0.26; PTW = 0.33–0.37; AW = 0.49–0.56.

Type material. Ex Coracina striata sumatrensis : Holotype ♂, Laboran [?], Sumatra, Indonesia, Jul. 1923, [E. Mjöberg], 770 ( MFNB).

Additional material examined (non-types)

Ex Coracina striata panayensis : 1♀, 8 km N of Siaton, Oriental, Negros, Philippines, 24 Jul. 1964, N. Wilson, BBM-6038 ( BPBM).

Ex Coracina striata difficilis [some as Coracina striata ]: 2♂, 2♀, Brooke’s Point, Palawan, Philippines, 31 Mar. 1962, Max Thompson, BBM-PI-785 (OSUS); 1♂, 1♀, Palawan, Philippines, 1947 (OSUS); 1♂, 1♀, Puerto Princesa, Palawan, Philippines, 16 Oct. 1941, Hoogstraal, 2662 (OSUS) [slide contains unidentified Guimaraesiella].

Remarks. Brueelia indonesiana was first described by Eichler (1947: 8), who separated it from “other Brueelia species (sens. strict.)” by its “completely rounded” temples and the brown sternal plates on abdominal segments III–VI. This description is accompanied by a drawing of some features of the ventral side of the head and the right half of the pro- and pterothorax, as well as some measurements.

We have examined material from three Coracina striata subspecies, and we identify the material as the same species. In the phylogeny of Bush et al. (2016), material from Coracina novaehollandiae (Gmelin, 1789) and C. pectoralis (Jardine and Selby, 1828) was genetically very similar to material from C. striata , as well as other specimens from other Coracina and Edolisoma spp. Although, these specimens are morphologically very similar, there are some differences in pigmentation patterns and the shape of the head and male genitalia. More specimens need to be studied to determine the host and geographic limits of Indoceoplanetes indonesiana .
