Laneella patriciae
(Wolff, 2013)
Mesembrinella patriciae
Wolff, 2013: 121
.
Holotype
male (CEUA), not examined. Type locality: Filandia,
Quindio
,
Colombia
. [NB: originally placed under
Mesembrinella
, later moved to
Laneella
based on DNA analysis and the examination of spermathecae which revealed they are tuberform like other
Laneella
(
Marinho
et al.
2017
)
.]
Laneella patriciae

;

Mesembrinella patriciae
:
Cerretti
et al.
(2017
: tab. 2).
Diagnosis.
A medium-sized fly averaging
9.4 mm
(9–10/5) in length. Abdomen bluish to purple-green vs. shiny brown in
L. fusconitida
sp. nov.
; mid and hind femora with apices dark brown in
L. patriciae
vs. entirely orange in
L. fusconitida
; male with surstylus straight in
L. patriciae
vs. curved forward in
L. fusconitida
. This species is very similar to
L. fusconitida
, both sharing the distinctive tuberform spermathecae and brown spot around crossvein r-m.
Redescription
. [Summarized from Wolff (2013).]
Male
. Head. Frons narrow (holoptic); fronto-orbital, parafacial and gena yellow with silvery tomentum; frontal vitta reddish-brown, obliterated above; postgena and occiput with white tomentum and fine long pale setae; antenna orange and palpus typical; postocular setae extending to gena. Dorsum of thorax reddish-brown with white tomentum and testaceous stripes; ppn and pleura orange with fine white tomentum; spiracles pale yellow. Coxae, trochanters and femora orange; mid and hind femora with dark reddish-brown apices; chaetotaxy: ac 2:3, dc 2:3, ia 1:2, kat 2:1, ppn
3x
3, meral setae in form of inverted L; ap scutellar setae 1:1. Wing hyaline with brown spot around crossvein r-m; subcosta bare; section IV about 0.30 of III (estimated from Wolff 2013: fig. 1); calypters with dark rims. Abdomen with dorsum bluish to greenish-purple except T1+2 yellow; T1+2 and T3 with lateral marginal setae; T4 and T5 with rows of marginal setae; disc of T5 without row of stout setae, whole segment with short fine setae. T6 partially fused with T7+8; pregonite apically truncated; tip of paraphallus with dorsal line of denticles; hypophallus shorter than paraphallus; epiphallus long and thin; cercus and surstylus slightly curved backward in lateral view (see Wolff 2013: fig. 2).
Female
. Dichoptic, frons broad and reddish-brown.
Material examined.
None (no specimens could be obtained for examination).
Distribution.
Colombia
.
Remarks.
A single sequence of this species from GenBank (
KR820718
) was added to our molecular analysis. It was distinct from other species and was recovered close to
L. fusconitida
sp. nov.
(
Fig. 488
) with a genetic divergence of 3.84%, which supports them as two separate species; this is supported also by the several morphological differences as listed above.
