Diagnosis.

Compared to other species in the genus Paraglenurus , P. albiventris has the morphological characteristics of largely whitish tergites II – V in the male, a usually weak preapical dark brown marking on the hindwing, and a vertex that is very wide and well-developed.

Description.

Male, adult. Head (Fig. 22 B, C View Figure 22 ). Vertex wide, strongly raised, reddish brown. Frons yellow, with broad dark brown band extending from below vertex to below base of antenna; clypeus yellow, with long black hairs. Antenna dark brown, long, with slightly defined club, densely covered with short black hairs; flagellum comprising ~ 42 flagellomeres, each flagellomere with distal yellow annulation. Mouthparts yellowish white; labrum yellowish white, with hyaline yellow hairs; maxillary palpus yellow; labial palpus yellow, spindle-shaped.

Thorax (Fig. 22 C View Figure 22 ). Pronotum slender, longer than broad, brown, with long brown hairs. Mesonotum and metanotum dark brown, with yellow portions.

Legs. Coxae yellow, moderately covered with yellow hairs. Femora mostly dark brown, partly brown; moderately covered with black hairs. Tibiae dark brown; moderately covered with black hairs. Tibial spurs dark yellowish brown proximally, reddish brown distally, slightly long, slightly curved, approximately as long as tarsomere 1. Tarsi yellowish brown, tarsomere 5 as long as tarsomere 1; claws brown.

Wings (Fig. 22 A View Figure 22 ). With white and dark brown markings. Forewings veins and crossveins dark brown; presectoral area with 10 or 11 pterostigma yellowish white; RP arising beyond CuA fork; CuP supporting one cell before fusing with 1 A; 2 A fused with 3 A; pterostigma white; anterior Banksian lines absent; posterior Banksian lines absent. Hindwing slightly shorter and narrower than forewing; presectoral area with one crossvein; RP arising before MP fork; pterostigma white; anterior Banksian lines absent; posterior Banksian lines absent; male without pilula axillaris.

Abdomen (Fig. 22 A View Figure 22 ). Shorter than hindwing, yellowish brown, densely covered with pale brown hairs; tergite II – V largely yellowish white.

Genitalia (Fig. 22 D, E, H – K View Figure 22 ). Ectoproct semicircular, with long black setae. Sternite IX narrow, covered with long black setae. Gonarcus brown, arched. Mediuncus lightly sclerotized, brown, moderately hooked in lateral view. Parameres well sclerotized, dark brown, triangular in caudal view.

Size. BL: 31.7–34.7 mm; FWL: 32.7–34.6 mm; HWL: 32.5–33.3 mm.

Female, adult. General morphology, except coloration of abdomen and terminalia, almost as in male. Abdomen: dark brown, tergite II – VII each with median triangular pale marking at posterior end; tergites III – V each with pair of large pale spot medially (Fig. 25 View Figure 25 ). Terminalia (Fig. 22 F, G View Figure 22 ): tergite VIII wider than tergite IX; tergite IX narrow, triangular in lateral view; ectoproct semicircular in lateral view; lateral gonapophyses semicircular in lateral view, smaller than ectoproct; posterior gonapophyses long, curved, with long black setae; anterior gonapophyses absent; pregenital distinct, plate triangular, presented on membrane below tergite VIII.

Size. BL: 25.8–31.1 mm; FWL: 29.4–36.2 mm; HWL: 28.3–35.2 mm.

Biological notes.

Paraglenurus albiventris is a species frequently observed in open environments, such as coastal dunes and inland grasslands, and is distributed throughout South Korea (Fig. 37 E View Figure 37 ). Adults emerge earlier than other Paraglenurus species in Korea, appearing from June. Larvae are known to be ambush hunters. They were not examined during this study; for details on their ecology, refer to Matsumoto et al. (2021).

Distribution.

Korea (new record), Japan ( Matsumoto et al. 2021).

Remarks.

Paraglenurus albiventris was described by Matsumoto et al. (2021) based on specimens from Japan. A taxonomic review of the genus Paraglenurus is needed in countries where it has been previously recorded.
