Coridromius declivipennis Miyamoto and Yasunaga View in CoL Figures 4, 6, 10E–H, 11A, map 6
Coridromius declivipennis Miyamoto and Yasunaga, 1999: 35–37 View in CoL (n. sp.).
DIAGNOSIS: Recognized by the following combination of characters: bilobed proepisternum; rounded and cleft right paramere; long left paramere, sharply curved at base; embolium angularly flared near cuneus. Similar to crassus , nakatanii , and pteraulos but with shorter ventral apical process on the pygophore than in crassus and pteraulos , and different hemelytral shape, and coloration to all three.
REDESCRIPTION: COLORATION (figs. 4, 6): Mostly light brown with orange and brown markings. Head: Yellow-brown to orange-brown; vittae absent; ocular margins and posterior margin of head yellow; three dark brown spots, one immediately above clypeus and one over each antenna; clypeus, gena, mandibular and maxillary plates slightly paler; buccula dark brown basally then becoming yellow; labrum orange-brown, labium yellow, brown apically. Antenna: AI dark brown, base and apex yellowed; AII light orange-brown with pale subapical annulation and dark brown apical annulation; AIII and AIV dark brown, yellow basally. Thorax: Pronotal collar yellow; pronotum mostly orange-brown with faint yellow medial stripe, yellow margins and faint yellowing at humeral angles; mesoscutum light orange-brown; scutellum orange-brown to dark brown, with faint yellow apex and sides; thoracic pleura mostly orange-brown, posterior margins yellowed; lobes of proepisternum yellow, ventral portion of posterior lobe dark brown. Hemelytra: Yellow-brown to dark brown, darker anteriorly, yellow posteriorly; clavus yellow at commissure; corium and embolium yellow from apex of claval commissure to costal fracture; cuneus yellowbrown to orange-brown, sometimes darker apically; membrane brown with dark brown veins. Abdomen: Mostly yellow-brown to orange-brown, sometimes with dark brown markings around spiracles. Legs: All coxae pale yellow; pro- and mesofemora yellow, brown apically; metafemur yellow basally, becoming brown apically, with diagonal brown striping on outer surface, sometimes dark brown immediately below striping; tibia yellow, sometimes slightly brown basally. SURFACE AND VESTITURE (figs. 4, 6): Head weakly punctate laterally and medially, densely setose; pronotum, propleuron, metepimeron, scutellum, and hemelytra finely punctate, clothed in long, simple, white, decumbent setae; male with short, dense and thick conelike setae on the left posteroventral margins of abdominal segments VII and VIII. STRUCTURE (figs. 4, 6): Head: Frons tumescent medially, merging with punctate minor swelling on vertex; vertex with two minor swellings adjacent to eyes, shallow depressions behind each swelling; posterior margin of head rounded, weakly carinate. Thorax: Pronotum broad and steep, posteriorly rounded, finely punctate; margins carinate, anterolateral margins somewhat depressed, not upturned, submarginal region of humeral angles excavate; callar region weakly defined; proepisternum bilobed; posterior margin of metepimeron truncate, upper corner slightly extended and rounded; metanotum prominent and flared; scutellum somewhat flattened. Hemelytra: Costal margin carinate, distally expanded. Legs: Metatibial spines long and thick. Abdomen: When viewed laterally, posterolateral margin of segment II angular. MALE GENITALIA: (figs. 10E–H, 11A) Right paramere broad and rounded with thumblike lobe, paramere appears U-shaped when viewed dorsally; left paramere thick and elongate, sharply angled basally, then evenly curved and tapering to apex with a slight twist along its axis, curved at tip; pygophore with a long mesal suture; ventral apical process broad and short (figs. 10, 11A). FEMALE PARA- GENITALIA: Abdominal tergite II asymmetrical, right lateral margin weakly tumescent, posterior margin sulcate.
REMARKS: Based on the modifications of the female dorsum, it is thought that males inseminate females dorsolaterally.
HOST: No host records.
DISTRIBUTION: Known from Kyushu, Japan (map 6).
