Abstract

Gigasanalis jianfenglingensis Long & Chen sp. nov. urn:lsid:zoobank.org:act: 063141DE-7F55-4EF6-9BDD-6DE7ADA48D16 Figs 1–21 Diagnosis The salient features of this new species following: 1) aedeagus with phallobase bilaterally symmetrical, dorsal periandrial lobe shovel-shaped with apex broadly concave (Fig. 14); 2) each paired inner penis rod with apex rod like and with three dorsal spines located at subapical (Figs 14–16); 3) anal segment in dorsal view (Fig. 10) approximatively oblong-shaped, epiproct distinctly exceeding apical margin of anal segment, anal style with slightly exceeding apical margin of epiproct; 4) genital style with lobes tortuous and irregular, apical margin almost rounded (Figs 11–13). Etymology The species name refers to the type locality, Jianfengling National Natural Reserve, Hainan Province, China.

Yellowish white to dark brown (Figs 1–4). Vertex yellowish brown (Figs 1, 3, 5). Frons brown, area along lateral margin with a broad longitudinal yellowish white stripe from upper margin to below level of antennae (Fig. 7). Clypeus, rostrum and antennae brown. Genae yellowish white with area beneath antennae brown (Figs 2, 4, 6). Eyes and ocellus generally reddish brown (Fig. 6). Pronotum with area between lateral carinae (containing median and lateral carinae) dark brown, lateral lobes yellowish white, and ventral lobes brown (Figs 1–7). Mesonotum and tegula yellowish white (Figs 1, 3, 5). Fore wing dark brown to yellowish white, area at base yellowish white, costal margin with one small sharp triangle yellowish white marking and one large yellowish white stripe, and with another large triangle yellowish white marking at costal cell, area from base of postcostal cell to radial cell, median cell and base of C5 with numerous, small, yellowish white spots, main veins brown with branches pale brown to reddish brown, and short cross veins yellow to yellowish brown (Figs 1–4, 8).

Pygofer in lateral view (Fig. 11) with posterior margin broadly convex in the middle, medioventral process (Fig. 12) with apical ½ divided into two large branches, each with apical margin roundly convex. Aedeagus with phallobase bilaterally symmetrical (Figs 14, 16), dorsal periandrial lobe shovel-shaped with apex broadly concave (Fig. 14); lateral periandrial lobe in lateral view (Fig. 15) large finger-like with apical margin roundly convex; ventral periandrial lobe in ventral view (Fig. 16) with basal ⅓ neck-shaped, apical ⅔ subquadrangular with two basal horn-shaped processes large, directed laterally, with two apical horn-shaped processes small and acuate, directed apically. Dorsobasal suspensorium broad and flaky (Figs 14, 16). Each paired inner penis rod with apex rod like and with three dorsal spines located at subapical (Figs 14–16). Connective with basal ⅓ relatively stout and apical ⅔ finger-like (Fig. 15). Anal segment in dorsal view (Fig. 10) approximatively oblong-shaped, with ratio of length to maximum width 1.6, with basal margin with a reentrant angle of about 90 degrees in midline, epiproct tongue-shaped, distinctly exceeding apical margin of anal segment, anal style with apical margin broadly convex and slightly exceeding apical margin of epiproct; in lateral view (Fig. 11) anal segment with ventral margin with two dumpy processes, apical margin subtruncate, anal style approximatively banana-shaped, hanging at the apex of anal segment ventrad, with length nearly as long as anal segment. Genital style with lobes tortuous and irregular, apical margin almost rounded (Figs 11–13). FEMALE TERMINALIA. Sternite VII with posterior margin distinctly concave as U-shaped, anterior margin obtuse angle-shaped producing basad (Fig. 17). Anal segment (Figs 18–19) in dorsal view suborbicular, basal margin broadly concave, apical margin incised in the middle; epiproct with apical margin incised in the middle, exceeding apex of anal segment; anal style with apical margin roundly convex and distinctly exceeding apical margin of epiproct. Gonapophysis VIII with spines at the outer and inner lateral margins respectively 4 and 1 (Fig. 20). Gonapophysis IX with two lateral lobes incompletely symmetrical, narrowing and sharp apically (Fig. 21).
