Alujamyia octopuncta Norrbom , n. sp.

( Figs 1–5, 8)

LSID: urn:lsid:zoobank.org:act:14315F28-874D-4B30-BB5A-954816F6E5D7 .

Etymology: The name of this species is a noun in apposition, in reference to the four pairs of brown spots present on the scutellum and abdomen.

Diagnosis: This species differs from all other species of Alujamyia in having the scutellum dorsally and the notopleuron microtrichose, and the wing with the posterior apical band present only from vein R 4+5 to the posterior wing margin. It differs from the other species except A. sexvittata Norrbom in having a complete subbasal band, and from the other species except for some specimens of A. farri Norrbom in lacking brown markings on the scutum. It differs from the Antillean species ( A. farri and A. isolata Norrbom ) in lacking a subcostal band and in having orange brown setae, and from the other Mesoamerican species ( A. bella Norrbom and A. sexvittata ) in having a complete anterior apical band connected anteriorly to the subapical band.

Description: Body length 5.0–6.0 mm. Mesonotum length 2.5–2.7 mm. Wing length 5.3–5.7 mm. Setae orange brown.

Head ( Fig. 2). Antenna yellow except most of arista brown; first flagellomere moderately long, 2.25–2.40× as long as wide, reaching or almost reaching ventral facial margin.

Thorax. Mesonotum ( Fig. 5) mostly orange. Scutum orange except for white areas (poorly differentiated), at least paired lateral postsutural white vittae present, without brown markings. Scutellum white except for paired circular dark brown spot on base laterally, extending dorsally only to basal scutellar seta. Pleuron ( Figs 1, 3) orange except for white areas. Mediotergite entirely orange. Scutum nonmicrotrichose except postsutural margin lateral to supra-alar seta; notopleuron microtrichose except dorsal margin; scutellum nonsetulose, entirely microtrichose dorsally, microtrichose only on distal half laterally.

Legs. Entirely orange.

Wing ( Fig. 8). With 5 bands: subbasal band extended to base of vein CuA+CuP, orange except posterior margin narrowly brown in cells c and br; discal band orange with brown margins, relatively broad, its proximal margin covering crossvein bm–m, its distal margin covering basal half of pterostigma, but band narrow and entirely brown in cell m 4; subapical band orange with brown margins, entirely brown posterior to middle of cell dm, broad, covering crossveins r–m and dm–m, with proximal and distal margins convex, not parallel to crossvein dm–m, its proximal margin without sharp bends; anterior apical band complete, connected to subapical band, mostly brown but partially orange in cells r 1 and r 2+3; posterior apical band narrow, extended from vein R 4+5 to posterior wing margin or interrupted in cell r 4+5, very narrowly connected to subapical band along vein R 4+5.

Abdomen ( Fig. 4). Tergites 3, 4 and 5 each with pair of sublateral dark brown spots, 2–3× as broad as long on tergites 3 and 4, circular on tergite 5.

Female terminalia. Oviscape orange, 1.3–1.4 mm long. Aculeus gradually tapered to long, acute tip.

Holotype: ♀ ( MNCR INBioCRI0003826274) Costa Rica: Puntarenas: P. N. Corcovado, Sector La Leona , Cerro Puma, LS 267700 518900, 100–300 m, Malaise trap #2, 19.vi–8.vii.2003, M. Moraga, A. Azofeifa & K. Caballero.

Paratype: Costa Rica: 1♀ same data as holotype except Malaise trap #7, 16.ix–6.x.2003, K. Caballero ( USNM INBioCRI0003780172) .

Distribution: This species is known only from Costa Rica.

Biology: The host plants and biology of this species are unknown.

Comments: Within Alujamyia , the new species appears to be more closely related to the other Mesoamerican species, A. bella and A. sexvittata . They share the following synapomorphies (character numbers following Norrbom (2006)): 40.2 (subbasal band present from crossvein h to apex of cell cua), 44 (discal band shifted basally, touching crossvein bm–m), 47 (discal and subapical bands mostly orange with brown margins), 49 (subapical band not parallel to crossvein dm–m, anteriorly curved or angled more proximally), and 53.4 (abdomen yellow, with paired sublateral brown spots on tergites 3–5, female tergite 6 yellow). The presence of the distal part of the posterior apical wing band (52.1), the plesiomorphic state, suggests that A. octopuncta may be the sister group to the other two species, in which this band is reduced. The isolated anterior apical band may be another synapomorphy for A. bella + A. sexvittata . It is complete and connected to the subapical band in A. octopuncta .
