Banyallarga (Banyallarga) columbiana (Navás)

Fig. 5

Anisocentropus columbianus Navás 1934a:174 [Type locality: Colombia, Santander, Pamplona; MNHNP; original description implies female, but type is male].

Banyallarga columbiana — Flint 1983:77.

This species is known only from the type specimen, which is in rather poor condition, lacking a head, most of its legs, one hind wing, and all the wing hairs. The phallic endotheca is not everted, so that portion is not described. Banyallarga columbiana is distinguished from other species in the subgenus Banyallarga by the shape of tergum X, which is broad and truncate apically in dorsal view, and has a sharp dorsomesal ridge ( Fig. 5A, B ). Tergum X is also broad in B. penai , but it is shallowly emarginate apically.

Adult. Forewing length 10.9 mm (n=1).

Dorsal pterothorax golden brown; ventrolateral thorax and legs golden brown. Tibial spurs 2:4:3 [according to Navás's description; hind leg of specimen missing]. Hind wing of male with basal semimembranous sleeve or pouch, enclosing brush of long setae (as in Fig. 32B ).

Male. Tergum IX with darkly sclerotized anterior ridge, posterior margin concave; lateral ridge present; sternum IX with posterior sublateral ridges. Preanal appendage subequal to tergum X, rounded apically, with short setae on apical half ( Fig 5B ). Tergum X truncate apically, with a sharp dorsolateral ridge ( Fig. 5B ); in lateral view posterior margin oblique ( Fig. 5A ). Inferior appendage simple, with long setae ventrally and laterally on coxopodite; harpago rounded apically, of uniform circumference, with peglike setae apically. Phallus with phallotremal sclerite U­shaped.

Female. Unknown

Material examined. COLOMBIA: Santander: Pamplona, 2300 m, 1920, Rochereau — holotype male ( MNHNP) .

Distribution. Colombia.
