Figs 21–27

Diagnosis

A medium-sized yellow species of the albiseta -group. Postpedicel brown, a little more than 5 times as long as wide; stylus white, about as long as postpedicel. Mid tibia with short yellow apical sharp spur, shorter than tibia is wide.

Etymology

The word ‘manjano’ means yellow in Turumbu, language that is spoken in Yangambi. It refers to the yellow body colour of the new species.

Type material

Holotype ♂, DR Congo, Yangambi , 27 May 2013, primary mixed forest (0°48’04.69” N 24°31’37.87” E; reg. 33015; leg. P. Grootaert; MS name Plat 5), mid leg in position AB42406125 was extracted for DNA. A COI barcode can be found in GenBank with accession number: KJ768329 .

Description

Male

LENGTH. Body 2.4 mm; wing 2.7 mm.

HEAD. Entirely black. Occiput greyish pollinose; with 1 pair of long black verticals. Ocellar tubercle greyish pollinose, with 2 black, short anterior and 2 minute posterior setae. Frons very narrow, somewhat widened toward ocellar tubercle, above antennae nearly as broad as anterior ocellus, greyish pollinose. Face very narrow, narrower than anterior ocellus, greyish pollinose, clypeus subshining. Antenna with scape, pedicel and postpedicel brown; postpedicel conical, long, 5.3 times as long as wide; stylus white (except basal segment), long pubescent, about as long as postpedicel. Proboscis brownish, long, nearly as long as head is high. Palpus yellow, small, ovate, with scattered setulae and a long brownish subapical seta.

THORAX. Almost entirely yellow, only postpronotal lobe, notopleuron narrowly along lower margin, anepisternum (= mesopleuron) narrowly along upper margin and anterior spiracle yellowish brown; scutum shining, otherwise thorax subshining; bristles brownish. Postpronotal lobe elongate narrow, with 1 minute seta. Mesonotum with 2 notopleurals (anterior seta very short, posterior seta long, strong), 1 long strong postalar and 4 scutellars (apical pair long and cruciate, lateral pair very short); acrostichals very short, scattered, arranged in 2 broadly spaced rows; dorsocentrals uniserial, sparse, nearly as long as acrostichals, 2 prescutellar pairs somewhat longer.

LEGS. Almost entirely yellow, except for fore tibia and apical four tarsomeres more brownish than fore femur; mid and hind leg with only apical tarsomere brownish. Coxae and trochanters with ordinary yellowish to brownish setae of different lengths. Fore femur slender; with very short anteroventrals and 4 fine moderately long brownish posteroventral setae on about basal half. Fore tibia slender, clothed with ordinary setulae. Mid femur very thickened; with double row of black ventral spinules and row of long, black posteroventral setae ( Fig. 24 ). Mid tibia bearing a row of black ventral spinules; with very short flattened apical spur. Hind femur slender, with short anteroventral setae. Hind tibia slender, clothed with ordinary setulae. Tarsi of all legs unmodified.

WING. ( Fig. 22 ) Finely, uniformly infuscate, with brownish veins. Costa between R 1 and R 2+3 darkened. One moderately long costal seta. Veins R 4+5 and M 1+2 almost parallel just before meeting wing margin. Crossveins m-cu and r-m contiguous; cell bm longer and distinctly broader than cell br; Vein CuA 2 somewhat sinuate reaching wing border. Anal vein distinct in apical part and evanescent in basal part. Calypter brown, with about 10 brown setae. Halter darkened.

ABDOMEN. With brownish tergites and yellowish sternites (except segment 8); tergites covered with short brownish setae; sternites with similar but somewhat longer setae; segment 8 bearing numerous very long black strong setae. Terminalia ( Figs 25–27 ) moderately large, brown. Left cercus ( Fig. 26 ) much longer and broader than right cercus, clothed with long unmodified setae. Left epandrial lamella much shorter than right epandrial lamella bearing about 4 long apical setae.

Female

Unknown.

Comparison

In Smith’s (1969) key the new species runs to P. rhodesiensis Smith, 1969 that was described from females found in Rhodes-Inyanya National Park in Zimbabwe. However the latter has scape and pedicel yellow. In P. manjano sp. nov. the scape and pedicel are brown. In P. rhodesiensis the scutellum is reddish yellow, but blackish on disc and sometimes completely black. In the new species the scutellum is yellow.

Distribution

DR Congo.
