Description. Adult, male (N =3). General coloration brownish-yellowish gray. Body length 4.8–5.1 mm. Wing length 5.0– 6.2 mm.

Head. Dark brown, nearly black, dusted with brownish gray pruinosity more intense along eye margin, covered with sparse erect setae, vertex with small tubercle. Eyes holoptic, large and touching each other dorsally. Antenna 1.35 mm long, entirely dark brown, scape elongate, nearly cylindrical, pedicel oval, flagellomeres elongate with distinct apical pedicels ( Fig. 8 View FIGURES 7–12 ), increasing in length distally. Apical flagellomere 1.5 times as long as preceding segment. Longest verticils as long as respective segments. Rostrum brownish gray. Palpus dark brown. Mouth parts brownish.

Thorax. Cervical sclerites blackish laterally, pale dorsally and ventrally. Thorax yellowish-brownish gray. Pronotum dark brown with a yellowish dorso-lateral spot. Mesonotal prescutum brownish-yellowish gray with a wide brown medial stripe that is very distinct posteriorly and fading anteriorly. Lateral stripes absent. Scutal lobe dark brown dorsally, brownish yellow laterally. Pale area in the middle between scutal lobes. Scutellum brownish yellow with blackish fronto-lateral margin. Mediotergite yellowish-grayish brown with yellow lateral and posterior margins. Pleuron with distinct dark brown to blackish stripe extending from cervical sclerites to the base of abdomen, same color as prescutum above stripe and pale yellow below. Wing ( Fig. 2 View FIGURES 1–6 ) with brownish tinge, yellowish before arculus. Stigma distinct, dark brown. Base of Rs and apex of Sc 1 / Sc 2 surrounded by brownish areas. Indistinct darkening along cord and along distal margin of discal cell. Venation: Sc long, Sc 1 ending at about two-thirds of Rs, Sc 2 ends slightly before apex of Sc 1. Rs long, distinctly arched at base. R 1 oblique, R 2 oblique at tip of R 1. R 3 and R 4+5 slightly arched, parallel to each other. Discal cell twice as long as wide. Basal deflection of CuA 1 at branching point of M. Vein A 2 slightly sinuous. Cell a 2 medium-wide, anal angle widely rounded. Halter pale grayish-brown. Length of halter 0.7–1.0 mm. Fore coxae dark brown and posteriorly yellowish; second and third pairs pale yellow. Trochanters pale yellow. Femur brownish gray with pale base and darkened apex. Tibia dark brown with blackened distal end, basal tarsomeres dark brown, distal blackish. Male femur I: 4.7 mm long, III: 5.35 mm, tibiae I: 5.9 mm, III: 5.3 mm, tarsus I: 6.0 mm, III: 4.5 mm.

Abdomen. Abdominal tergites dark brown, basal part of 3–6 tergites pale yellow. Sternites pale, distal margins of 3–7 sternites widely dark brown. Eighth segment entirely dark brown, except the posterior margin of the sternite, which is paler. Male terminalia ( Figs. 9–12 View FIGURES 7–12 ) large and complex. Ninth tergite obscure yellow with widely brownish posterior margin. Gonocoxite brown, slightly longer than wider, with large and complex subapical ventro-mesial lobe resembling a bird´s head ( Fig. 10 View FIGURES 7–12 ). Outer gonostylus long, narrow, hook-shaped, blackened distally. Inner gonostylus complicated: small setose tubercle on dorsal surface, long, rod-shaped lobe with hooked distal part on mesial surface, distal part extends into elongate beak that bends behind mesial lobe. Paramere with long, arched and blackened distal part, penis very large and complex, bifid at apex ( Fig. 12 View FIGURES 7–12 ).

Female. Unknown.

Habitat. Young grove of deciduous trees. Species is attracted to light ( Fig. 13 View FIGURE 13 ).

Elevation. Species was collected at about 30–40 m elevation.

Period of activity. Mid-June.

Distribution. Currently known only from South Korea.

Remarks. A. kleini sp. nov. has very complex male terminalia, which is common among other Atypophthalmus s.s., but these particular structures, e.g., the ventromesial lobe of gonocoxite, inner and outer gonostyli, and penis are very specific. General body coloration resembles that of other Korean Atypophthalmus s.s., including a distinct dark brown or black stripe on the yellowish pleuron. Cross-banded abdomen and patterned wings are similar to that of A. (A.) crinitus ( Alexander, 1924) , both species have some similarities in structure of male terminalia, but details are very distinct, especially the complex ventromesial lobe of gonocoxite in A. kleini sp. nov., which is missing in A. crinitus , and a very complex enlarged penis in A. kleini sp. nov., whereas that structure is simple in A. crinitus .

Etymology. Species is named after entomologist Dr. Terry A. Klein, who collected new species as well as many other crane flies in South Korea.
