Chimarra circumverta , new species
( Figs 10 View FIGURES 7–13 , 33–38 View FIGURES 26–38 )
Diagnosis. The male of this species is distinguished from those of other described Afrotropical species by the presence of strongly sclerotized lateral lobes of tergum X, forming a complex of sharply pointed structures curved dorsad and anterad. The inferior appendages are most similar to those of C. bertrandi Scott 1974 , from Zimbabwe, each with a prominent dorsomesal process, however the dorsomesal process of C. circumverta is blunt in contrast to the sharp process of C. bertrandi . The inferior appendages of C. circumverta each also possess a second mesal process, absent in C. bertrandi , partly covered by the dorsomoesal process.
Description, male: Colour (in alcohol): Head yellowish; antennae light brown; head setal warts light brown; thorax yellowish; thoracic setal warts light brown; terga light brown; wings pale yellow; foretibiae, -tarsi and -tibial spurs light brown, forefemora and –coxae and other legs yellowish; abdomen yellowish. Forewings each 6.5 mm (n=4) long, length over width ratio 3.2; barely visible opaque, hyaline spots distributed as in Fig. 10 View FIGURES 7–13 , Y-shaped indentation present anteriorly; discoidal cell twice as long as wide, originating shortly before mid length of wing; median cell shorter than discoidal cell; fork I originating after crossvein r at distance equal to 1.5 times length of crossvein r; fork III twice as long as wide. Hind wings each 5.3 mm (n=4), length over width ratio 2.8; anterior margin slightly curved.
Genitalia: Segment IX with two posteroventral processes elongate, slightly sigmoid, distally robust. Preanal appendages each minute, ellipsoid, setose, partly concealed by tergum IX in lateral view. Tergum X divided into pair of heavily sclerotized, black lobes directed caudad and then curving dorsolaterad in dorsal and lateral views; complex of 2 pairs of basal branches curving laterad with sharp apices; posterodorsal margin of segment IX darkly sclerotized. Inferior appendages each triangular, broad basally, tapered to acute apicodorsal angle in lateral view; posteroventral margin with sharp, darkly pigmented teeth-like processes; in dorsal view large, thumblike dorsomesal process partly covering large, sharp, dark sclerotized second mesal process; in ventral view apicomesal corner of each inferior appendage sharply pointed and triangular, heavily sclerotized; scattered setae on apicoventral surface and apical margins. Phallic apparatus with anterior half bulbous, slightly sclerotized subapically, apical 1/3rd strongly sclerotized, especially apical 1/8th and pair of sharp apical phallothecal spines directed slightly ventrad; short and thick endothecal spine present at mid length of retracted phallic apparatus.
Male holotype: Malawi: Mulanje Mountains: stream near Minunu hut, S15.92481°, E35.63856°, 2014 m, light trap, 11 November 2012, Loc # Ma 41a, leg. M. Espeland, S. Dupont and R. Murphy ( Fig. 1 View FIGURE 1 , locality #4) GoogleMaps .
Paratypes: Same data as for holotype, except 10 November 2012: 10 males, 5 females GoogleMaps .
Etymology. Circumverta from the Latin circum, around, and verta, turned, describing the elaborate and curved lobes of tergum X as well as the inward directed mesal process on each inferior appendage.
