Chimarra tokotaai, new species

Figs. 14, 75–79

Chimarra tokotaai is similar to C. vuda and C. naitasirensis in the presence of simple, dorsad-curved gonopods; a strongly enlarged phallotremal sclerite in the phallic apparatus; absence of large endothecal spines; and an endotheca with a group of minute, strongly sclerotized spicules. Chimarra tokotaai is distinguished from the other 2 species by having apically narrowed gonopods; a phallotremal sclerite that is 3x longer than the width of the posterior part of phallotheca; and the presence of only 1 group of sclerotized spicules in the phallic endotheca.

Male. Body dark pale brown, dorsal part of meso- and metathorax only slightly darker than rest of body. Large dark area between lateral and anterior ocelli. Foreleg anterior claw as long as foreleg spur.

Wing s (Fig. 14). Forewings 4.2 mm (n=1), brown; broad, ratio of length to breadth 3.3; R1 slightly curved before crossvein r; radial sector slightly produced anterad immediately before discoidal cell; discoidal cell originating slightly distally of mid-length of wing, nearly 3x longer than wide; median cell slightly shorter than discoidal cell; crossvein r originating from R2+3, immediately before fork I; fork I originating before crossvein s at distance equal to length of crossvein s; nygma located near base of fork II; fork III 1 /6th as long as wing; fork V as long as fork I, shorter than fork II; Cu2 tangential with A at wing margin. Hind wings 3.4 mm (n=1), brown; broad, ratio of length to breadth 3.0; margin slightly incurved at arculus, where Cu1 and Cu2 fused with margin; fork III as long as discoidal cell and 1/7th as long as wing; fork V about as long as fork I; 1A+2A 4x longer than 1A.

Male genitalia (Figs. 75–79). Segment IX slightly shorter than high; each anterodorsal margin shallowly concave in lateral view; each ventral margin strongly convex; each posterior margin produced posterad into large, triangular lobe starting at mid-height of cercus; ventral side of posterior 1/2 of segment IX with scattered setae (ventral view). In dorsal view with narrow anterior lobes; anterodorsal margin with wide, deep incision in dorsal view. In ventral view segment IX with shallowly concave anterior margin and moderately deep, and widely Ushaped posterior margin; posterior margin without central projection. Tergum X simple; tapering apically in lateral view (Fig. 75); orienting posteroventrad, nearly straight; divided into 2 slightly mesad-curved, lateral branches from base in dorsal and ventral view (Figs. 76, 77); each branch slightly narrowing posteriorly in dorsal and ventral view, apically rounded, without processes; sensillae invisible. Cerci large, broad, located immediately below dorsal margin of segment IX and tergum X and oriented posterad in lateral view; very short in dorsal view; covered by long setae. Gonopodsunbranched, about as long as segment IX, curved dorsad and sickle-shaped in lateral view; anterodorsal margin concave; ventral margin nearly straight; posteroventral corner slightly produced into strongly sclerotized minute tooth; in ventral view forming broad plates widening posteriorly, each with strongly sclerotized apicomesal tooth; each mesal margin nearly straight, weakly undulating. Phallic apparatus nearly 2x longer than rest of genitalia: phallotheca, in lateral and ventral view, with anterior part 2– 3 x thicker than posterior part; apicoventral spine absent on phallotheca; strongly enlarged phallotremal sclerite in phallic apparatus forming paired rays and about 1/2 as long as phallic apparatus; large endothecal spines absent; endotheca with1 group of minute, strongly sclerotized, well separated spicules.
