The illustrations PC1-6 show the overall genitalia parts which are volsella, gonostylus and gonocoxite.
PCA based on the data from the shape of volsella, gonostylus and gonocoxite is summarized in a scatterplot matrix shown in Figure 4.
can be distinguished from known species of the genus by the following combination of characters: a spherical median volsella with 9-10 long setae, the basal lobe of the superior volsella with 10-12 setae, tergite IX without median seta, and the absence of pigment marks on the wings.
Derived from the Latin "globosus", meaning spherical, referring to the round shape of the median volsella.
Superior volsella club-shaped, with one inner seta, 3 apical setae and 3 lateral setae, 2156 (8) long, 10-20 (8) wide at base, 22-32 (8) wide at apex.
These authors proposed a codification for several taxonomically informative characters that is adopted in this study; particularly, the anal tergal band (= Tergitebander of Bidawid & Fittkau, 1995), base of anal point (= Typen des Ventrallobus of Bidawid & Fittkau, 1995) and type of superior volsella (= Typen von Anhang I of Bidawid & Fittkau, 1995).
- Superior volsella with 1 apical seta.............................................
(U.) bingoparadoxum is characterized by the following combination: anal point robust, nearly parallel-sided and abruptly tapered to near pointed apex; superior volsella robust, abruptly narrowed apically to hook-shaped form, with two basal setae and one lateral seta, covered with microtrichia.
Gonocoxite 194-206  pm long, inferior volsella sub-rectangular with a dorsal lobe with 5-6  apical setae and a ventral lobe with 2-3  apical setae (Figs.
As a result, the most important characters used to define the Bryophaenocladius species are the shape of the anal point, the shape of inferior volsella, presence or absence of virga, shape of gonostylus, the presence and different degree of development of the crista dorsalis, presence or absence of the finger-like projection on palpomere 3 and wing punctuation.
The imagines are characterized by the following character combination: Ommateum with setae; antenna with 12 clavola; Wing vein R2+3 absent, squama without setae; mid and hind tibiae with one tibial spur; inferior volsella approximatively triangular, curved apically.
Inferior volsella approximatively triangular, curved apically, covered with microtrichiae and about 30-40 weak setae.
