Portanus haku sp. nov.

( Figs 13–24 )

Type locality. Parque Estadual do Cristalino , Novo Mundo, Mato Grosso, Brasil.

Diagnosis. Male: Pygofer ( Fig. 18 ), in lateral view, with posterior margin with acute apical projection directed posteroventrally. Style ( Fig. 20 ) apical portion not appearing bifid, with preapical lobe rounded and robust.Aedeagus ( Figs 22–24 ) with pair of ventral preapical processes long and acute, turned outward and measuring approximately two-thirds of the shaft length. Female: unknown.

Measurements (mm). Males (n = 8): body length, 4.1–4.5; crown length, 0.4–0.5; transocular width, 1.0–1.1; interocular width, 0.5–0.6; maximum pronotum width, 1.0.

Coloration. Crown( Fig.13 )brown; anterior margin bordered with dark brown line; apical third with subtriangular pale yellow marking between ocelli, which extends to posterior margin as a median line; basal two-thirds with pair of longitudinal reddish-brown maculae. Ocelli red. Face with dorsal third pale brown with pale yellow stripes and remainder two-thirds ivory ( Figs 15–16 ). Pronotum ( Fig. 13 ) brown, with several ivory spots. Mesonotum ( Fig. 13 ) brown; with pair of large anterolateral triangular dark brown maculae; posterolateral margins ivory. Scutellum pale brown to ivory. Forewing ( Fig. 17 ) translucent yellowish-brown; veins dark brown with alternating ivory spots; three dark brown maculae along costal margin; apex dark brown. Thoracic venter and legs ivory.

Description. Head ( Figs 13–16 ), in dorsal view, with anterior margin angulate; crown median length approximately four-fifths of interocular width and approximately half of transocular width; lateral frontal suture approaching the ocelli; epicranial suture not extending to imaginary transverse line between ocelli; texture shagreen. Pronotum ( Fig. 13 ) width subequal to transocular width; lateral margin angulate; posterior margin straight; texture smooth with transverse striae. Mesonotum ( Fig. 13 ) shagreen. Forewing ( Fig. 17 ) with distinct venation; with three closed anteapical cells; median anteapical cell slightly longer than the other ones. Metatibia with row AD with 10 long cucullate setae intercalated by 1-3 shorter setae; PD row with 10-11 very long cucullate setae, intercalated by 0-1 shorter cucullate ones; most of PD setae length 1.5x longer than AD setae. Hind leg with first tarsomere slightly longer than combined length of second and third; posterior margins with three, two, and zero platellae, respectively, between a pair of outer slightly longer cucullate setae.

Male terminalia. Pygofer lobe ( Fig. 18 ), in lateral view, longer than high; subtrapezoidal; posterior margin angulated; apex forming acute process directed posteroventrally; macrosetae distributed at dorsal posteromedian portion; some microsetae at apex. Valve ( Fig. 19 ), in ventral view, subquadrate; longer than wide; anterior margin straight; posterior margin convex, with acute point at middle; lateral margins angulate. Subgenital plate ( Fig. 19 ), in lateral view, extending posteriorly beyond pygofer apex; apical third upturned; in ventral view, basal third with transverse unpigmented line; with 6–7 robust uniseriate macrosetae and several long microsetae. Connective ( Fig. 20 ), in dorsal view, Y-shaped; anterior margin with short median basiventral triangular projection; apex truncate, not fused with aedeagus preatrium. Style ( Figs 20–21 ) with apodeme (basal portion anterad of connective articulation) long, one-fourth of style total length; apical portion enlarged, not appearing bifid; preapical lobe rounded and robust, with some long microsetae; apex elongated and thin, with digitiform process curving outward; in lateral view, subcylindrical and sinuous. Aedeagus ( Figs 22–24 ), in lateral view, with short preatrium; dorsal apodeme bifid and slightly sclerotized; shaft robust, subcylindrical and straight; preapical pair of processes long and acute, turned dorsally and outward, measuring approximately two-thirds of shaft length; in posterior view. Anal tube with segment X ( Fig. 18 ) subcylindrical; length two-thirds of pygofer dorsal margin length.

Remarks. Portanus haku sp. nov. is very similar to Portanus hastatus Souza & Takiya, 2014 and Portanus mariae Carvalho & Cavichioli, 2001 , due to color pattern and the shape of the pygofer, style, and valve. However, the new species can be distinguished from these and other Portanus species by the following features: (1) aedeagus shaft with apical third narrower than basal two-thirds; (2) pair of ventral preapical processes long and acute, turned outward; and (3) preapical processes length approximately two-thirds of shaft length.

Etymology. The species epithet is a reference to the character Haku from the animated movie Spirited Away by Studio Ghibli. The character is a dragon with horns, resembling the aedeagus preapical processes. The species epithet is treated as a noun in apposition.
