Carmenelectra Evenhuis, 2002 View in CoL
Carmenelectra Evenhuis, 2002c: 11 . Type species: Carmenelectra shechisme Evenhuis, 2002 , by original designation.
Carmenelectra pernigra Evenhuis , new species ( Figs. 11 View FIGURES 5 – 12 , 15, 16 View FIGURES 15 – 18 )
Types. Holotype male from Baltic Region: exact locality unknown; No. B-6336, in a smooth polished and rounded piece of golden yellow-colored amber, with no syninclusions and measuring roughly 12 x 9 mm in circumference ( Fig. 15 View FIGURES 15 – 18 ). Baltic amber; mid Eocene. Holotype currently in the personal collection of NLE; to be deposited in BPBM.
Diagnosis. This species is similar to C. shechisme Evenhuis but can be separated from it by the all black head (front and face yellow in C. shechisme ) and the all black mesonotum (with pair of thin admedian yellowish vittae in C. shechisme ).
Description. Length: 2.0 mm. Head. Black; eyes dichoptic, separated at vertex by slightly more than distance between lateral ocelli; front slightly depressed medially; antennae black; scape minute; pedicel subcylindrical, slightly longer than wide; first flagellomere lanceolate-ovoid, length about 2.5 x greatest width; second flagellomere slightly more than 2/3 length of first, with apical style; proboscis dark brown, length slightly less than 1/2 head height; labrum sclerotized, stiff, pointed apically, length slightly more than height of oral margin; palpus not evident.
Thorax. Black, with scattered short dark hairs on mesonotum and scutellum; coxae and legs brown; halter stem and knob brown.
Wing ( Fig. 11 View FIGURES 5 – 12 ). Subhyaline except for brownish infuscation anteriorly from costa to vein R4+5; veins brown; costa ends just before midpoint between ends of veins R4+5 and M1; vein Sc incomplete, ending at level just beyond origin of Rs; Rs evanescent at connection with R1; R2+3 ends at basal 1/5 between end of R1 and R4+5; R4+5 slightly curved to wing margin; vein separating cells br and bm distinct; vein M1 slightly curved toward wing margin; M2 fairly straight to wing margin; crossvein dm-cu closing discal cell absent; veins CuA1 and A1 straight to wing margin; sparse fringe of hair on posterior margin of wing.
Abdomen. Distended; dorsum and venter black, with scattered dark hairs. Genitalic features hidden, not discernable.
Etymology. The species-group epithet is from the Latin per, = “very”; + nigra = “black”; in reference to the striking black color of this species.
