Cyriotasiastes rhetenor solsonanensis Medina et al. 2023 Figure 1A–B, Figure 2A–B, Figure 3A–B Material examined: Holotype male, PHILIPPINES –Northern Luzon, Ilocos Norte, Solsona, vi.2023, D.Mapile leg. MMCP, to be deposited at PNM; Paratype female, PHILIPPINES –the same label as holotype; 1 female, PHILIPPINES –Northern Luzon, Kalinga, Pinukpuk, viii.2014, loc. Coll. DUBC; 1 female, PHILIPPINES –Northern Luzon, Nueva Vizcaya, Kayapa, vii.2017, loc. Coll. DUBC; 1 male, PHILIPPINES –Eastern Luzon, Isabela, vii.2013, loc. Coll. DUBC; 2 female, PHILIPPINES –Northern Luzon, Cagayan Valley, Santa Ana, vi.2014, loc. Coll. DUBC. Measurements of the various body parts (in range) are as follows: Males (n=3): LB (LH +LP+ LE) = 11.5–15.5 mm; LH = 1.5–2.0 mm; WH = 2.0–3.0 mm; LP = 2.0–3.0 mm; WP = 3.5–4.5 mm; LE = 8.0– 10.5 mm; WEH = 4.0–5.0 mm. Females (n=4): LB (LH +LP+ LE) = 18.0–19.0 mm; LH = 3.0 mm; WH = 3.0– 3.5 mm; LP = 3.0 mm; WP = 5.0 mm; LE = 12.0–13.0 mm; WEH = 6.0 mm. Redescription. Adult male. Teguments: head, prothorax, abdomen, and legs dark brown to matte black, antennae brown to dark brown. Head densely covered with tomentose white to yellowish pubescence, denser at the frons; long erect black setae randomly scattered at frons, denser at the posterior margin. Antennae dark brown, more than twice longer than body length, densely covered with very fine whitish recumbent pubescence; scape slightly robust, with apical cicatrix; antennomeres III–V of the same length. Eyes dark brown and mandible dark brown to matte black. Elytra twice longer than wide, tomentose, coarsely punctate near the base up to apical third, finer towards apical end; densely covered with light to dark brown recumbent setae; with three vertical bands of white to yellowish recumbent setae: slender S-shaped at the basal third, broad C-shaped at postmedian from elytral margin up to near suture, and a small band at the apical end. Elytra apical margin flat, elytral suture miniscule. Scutellum rounded, matte black, densely covered with recumbent white setae. Prothorax armed at each side, slightly recurved white band of longitudinal recumbent setae at each sides. Basal margin of pronotum lined with white recumbent pubescence, minute band of white pubescence near the basal margin, disc slightly raised. Legs dark brown to matte black. Coxae, trochanters black densely covered with white recumbent pubescence; femur and tibiae dark brown, densely covered with minute recumbent pubescence with erect golden-brown bristles at the apex. Claws dark brown. Prosternum, mesosternum, metasternum, abdominal sternites matte black covered with white recumbent pubescence. Metepisternum paralleled, lanceolate at the apical end, covered with whitish and yellowish recumbent pubescence. Pygidium matte black, widely ovate at apex, densely covered with yellowish and black erect setae. Genitalia. Endophallus approximately twice as long as the whole system of genitalia (Fig. 4A). Tegmen relatively slender, parameres broad; apex of parameres lined with long erect yellowish setae. Aedeagus strongly recurved when viewed laterally (Fig. 4I), slightly bottle-shaped ventrally (Fig. 4F), and apical third steeply angled towards a relatively blunt apical tip. Adult Female. Morphologically similar to males except females are broader and larger.Antennae slightly longer than body length but much shorter compared to males. Females have two-toned (basal third or basal half with whitish or yellowish recumbent pubescence, the other half covered with black recumbent pubescence) antennomeres III–VI, males do not have two-toned antennomeres. The S-shaped band of white pubescence at the basal third is much broader compared to the male. Distribution: Philippines (Northern Luzon: Ilocos Norte, Solsona; Kalinga, Pinukpuk; Nueva Vizcaya; Cagayan Valley, Santa Ana. Eastern Luzon: Isabela).
