Atopsyche (Atopsaura) kamakan Gomes & Calor , new species

Figures 4 A–G

Diagnosis. This new species belongs to the Atopsyche (Atopsaura) longipennis Group according to the shape of the apicomesal process of the first article of each inferior appendage which doubles the second article. The new species resembles to A. huarcu and A. sanctipauli in that the second article of each inferior appendage is broad basally and its apex is slender and curved so as to cover the apicomesal process of the first article ( Flint 1974) and in that the phallotheca has an elongate, curved, spine-like basodorsal process. This new species can be recognized by the shape of the anterodorsal lobe of the apicomesal process of the first article of each inferior appendage and by the upturned and uniformly slender basodorsal process of the phallotheca.

Description. Length of each forewing 5.52–6.56 mm (n = 19) ( Fig. 4 A). Overall body color yellow to dark brown. Head, frons and vertex with brown setae. Antennal scapes light yellow with long setae, pedicels light yellow; basal flagellomeres yellow, apical ones brown. Setose labial and maxillary palps with long brown setae. Dorsum of thorax with erect light and dark brown setae. Legs yellowish brown, coxae of all legs and foreleg tibiae dark brown, mid- and hind leg tibiae with yellow and brown. Forewings brown, erect setae of veins forming distinct pattern of alternating dark brown and yellow setae, with fewer, scattered white setae ( Fig. 4 A). Terga II, III, IV, V, VI and VII with elongate, coarse setae on posterolateral margins; terga III and IV each with pair of prominent, rounded glands located at anterolateral margins of respective terga. Sterna II, III, IV, V and VI with numerous minute setae; sternum VI process long, slender, curved, with longer, spine-like setae; process on sternum VII short, straight.

Male genitalia. Segment IX, in lateral view, longer ventrally tapering dorsally ( Fig. 4 C). Proctiger as viewed laterally, broadly widened apically, covered externally with numerous minute setae, lateral margins with several elongate setae. Parapods broad at base, narrow at tip, each with apicodorsal process upturned and with posterolateral process subapical; in dorsal view, parapods irregular with complex apex ( Fig. 4 D). Filipods absent. Preanal appendages small, rounded and setose. Inferior appendages each with first article relatively slender and four times as long as greatest width near mid length, apicomesal projection long and with mesolateral tooth; second article bilobed apically, anterodorsal lobe slender and acute and other lobe setose; in ventral view, second article broad basally and apicolateral margin parallel and closely aligned with the anteromesal projection of first article ( Fig. 4 G). Phallic apparatus relatively simple, apex divided mesally into pair of lateral “beaks”, in lateral view, “beaks” uniformly wide and rounded apically ( Fig. 4 E), slender in dorsal view ( Fig. 4 F); phallotheca with elongate, the upturned and uniformly slender basodorsal process, with dorsal tooth near middle, uniformly slender and apically upturned; aedeagus forming elongate curved spine, with basal sclerite ( Fig. 4 E).

Distribution. Brazil (Bahia).

Etymology. The Kamakã language ( Kamakan ), or Ezeshio, is an extinct language of a small family believed to be part of the Macro-Gê languages of Bahia State, near Brazil's Atlantic coast. Dialects included Kotoxó, Mongoyó/Mangaló, and Kamakã-Menien. The Kamakan native indigenous people lived in the neighbourhoods of the distribution area of the new species, now a municipality known as Camacan.
