Oliveira, Sarah Siqueira & Amorim, Dalton De Souza, 2010, Four new species of Paratrizygia Tonnoir from the Brazilian Atlantic Forest (Diptera, Mycetophilidae, Sciophilinae), Zootaxa 2629, pp. 29-46 : 34-40

Paratrizygia camargoi , sp. nov.

( Figs. 5 , 10 , 11 )

Diagnosis. Apical projections of gonocoxite tapering to the apex. Gonostyle wide at base, with a strong medial sinuosity, thin at the apex, with four apical elongated spines. Aedeagus with a medial incision at base. Female S8 with a pair of long, digitiform gonapophyses.

Material examined. Holotype ɗ, BRAZIL, State of Bahia, Ilhéus, Mata Esperança, Malaise trap, 14°46’ S, 39°04’ W, 15–18.v.2002, C.O. Azevedo et al. cols. (BIOTA-FAPESP). Paratypes 1 ɗ, same data as holotype; 1 Ψ, same data as holotype, except 18–21.v.2002.

Description. Male. Head. Vertex brown, with scattered setae. Three ocelli, mid ocellus smaller and slightly more ventral in position than lateral ones. Occiput brown. Eyes setose. Scape and pedicel rounded, yellow, with longer setae dorsally along apical margin; 14 brownish flagellomeres, almost twice longer than wide, with scattered setae and a short apical neck. Front and clypeus brownish, covered with short setae; labella yellow; maxillary palpus yellow, five palpomeres, basal palpomere very small, apical ones increasingly longer, last palpomere more than twice penultimate. Thorax. Scutum and scutellum brownish. Pleural sclerites brownish, pleural membrane yellow. Scutum moderately arched, covered with scattered small setae and stronger supra-alar, dorsocentral and acrostical. Scutellum with four scutellar bristles of slightly different sizes and many setulae. Pronotum densely setose, with some stronger setae. Anepisternum with some stronger setae and many setulae; katepisternum more or less squared ventrally. Mesepimeron reaching ventral margin of thorax, devoid of setae. Laterotergite only slightly projected, with setae of different sizes, suture separating from mediotergite incomplete dorsally. Mediotergite slightly curved on profile, ventral half with a pair of patches of longer setae and some setulae. Haltere whitish yellow, with some few setae on pedicel and more densely setose on knob. Coxae whitish yellow, femora, tibiae and tarsi yellow. Mid and hind first tarsomere more than twice the length of second tarsomere; mid and hind tibiae and tarsi with erect darker short bristles along almost entirely length, those on hind tibia more or less aligned dorsally and laterally. Tibial spurs 1:2:2, about twice the length of tibial width at apex, internal spurs shorter. Tarsal claws with a larger apical tooth and a smaller, more basal one. Wing ( Fig. 5 ). Length, 1.7 mm, width 0.6 mm. Membrane homogenously light brownish, no maculation; membrane densely covered with microtrichia on all cells, macrotrichia densely distributed, less so in the basal cells. Sc complete, ending in C just on base of Rs, setose, well sclerotized. C ending before wing apex, extending about a third the distance between R5 and M1. First sector of Rs almost transverse, devoid of setae, about as long as r-m. R1 relatively long, reaching C on apical third of wing; R5 reaching C quite before wing margin, well sclerotized; r-m almost longitudinal, well sclerotized, setose. M1+2 unforked; a loose vein between medial and cubital inforked veins (possibly M4); CuA complete, well sclerotized. A1 incomplete, not produce on the apical half. All apical veins with dorsal macrotrichia. Abdomen. Segments light brown, setose. T8 short and wide, S8 slender, longer than wide, rounded apically. Terminalia light brown, conspicuous. Terminalia ( Fig. 10 ). Gonocoxite setose, elongate, fused to each other only at ventral margin, with a pair of apical medial projections slendering to the apex, which on untreated specimens fold covering inner structures of the terminalia; gonostyle wide at base, with a strong medial sinuosity, thin at the apex, with four apical elongate spines; aedeagus slightly sclerotized, pointed at apex, with a medial incision at base; T9 long, setose, with four characteristic regular rows of spines at a apical fold facing ventrally; cerci not medially fused, weakly sclerotized, covered with setulae.

Female. As the male, except for the following features. Wing length, 1.7 mm, wing width, 0.7 mm. Antennal flagellomeres smaller, not so elongate as the male, near each other. Terminalia ( Fig. 11 ). Terminalia light brownish yellowish. Spermathecae not visible (but maybe present). S8 with a pair of long, digitiform gonapophyses, some longer setae laterally and some shorter at apex of gonapophyses; T8 wide, with setae only at lateral margins; S9 (genital fork) without an anterior medial extension; T9 wide and short, setae emerging from digitiform projections along apical margin; S10 membranous, with microtrichia; T10 not visible, maybe fused to T9; Ce1 slightly more than twice times Ce2 length, covered with microtrichia and few scattered setae; Ce2 ovoid, covered with microtrichia and some longer setulae.

Etymology. This species is named after Brazilian entomologist Dr. João Maria Franco de Camargo (1941–2009), an excellent teacher and a great naturalist, who devoted his professional career to the study Meliponinae bee biology and systematics. Dr. Camargo produced beautiful ink drawings of meliponines.
