Semirhytus anthurii Costa Lima et Guitton, 1963 Monitoriella anthurii Shenefelt, 1975 View in CoL

Description. Holotype Ƥ. Body length: Ƥ 4.3–4.4 mm.

Head ( Figs 8 View FIGURES 5 – 8 , 16 View FIGURES 13 – 16 ). In dorsal view 2.15–2.20 times wider than high; 1.1 times wider than mesoscutum. Eye in lateral view 1.75 times longer than temple. In frontal view, head 1.4 times as wide as high; malar space large, 0.75– 0.80 times the eye height. Face rugulose, polished medially, 1.7–1.8 times wider than high, 0.58 times as wide as head, gena smooth; middle face weakly elevated just bellow the antennal bases, the raised area concave and polished. Clypeus strongly protruding dorsally; its outline almost orthogonal to face in lateral view. Mandible densely setose except on teeth, ventral tooth longer than dorsal. Frons and vertex granular-rugulose; ocellar triangle elevated. Ocelli small, maximum diameter of posterior ocellus equal to slightly larger than distance between posterior ocelli; shortest distance between eye and ocellus 4.5 times the maximum diameter of posterior ocellus. Occipital carina distinct, absent mid-dorsally. Antenna about as long as body; flagellomere setae shorter than its width; flagellum with 33 joints, flagellomeres becoming shorter gradually toward apex. Maxillary palpi 5 segmented, labial palpi 4 segmented.

Mesosoma ( Fig. 11 View FIGURES 9 – 12 ). 1.46–1.50 times longer than high, 1.0–1.1 times higher than wide. Anterior declivity of mesonotum vertical; median mesonotal lobe bare along the midline, and deeply indented medially; lateral lobes bare medially, setae restrict to its margins. Notauli very deep and crenulate anteriorly, and converging in a rugose patch posteriorly, the sculpture area extending 0.25 the length of mesoscutum and bearing a median carina. Prescutelar pit divided by single carina in two deep and polished pits, with a pair of lateral short stubs. Metanotum laterally smooth, weakly crenulated centrally. Propodeum rugose on posterior half, smooth anterodorsally except for some rugosity medially, median carina indistinct, the unsculptured area separated by a distinct carina from the rugose lateral sculpture; posterolaterally with short tubercles; lateral carina between propodeum and metapleuron indistinct to absent. Metapleuron rugose. Sternaulus shallow and rugose anteriorly, absent posteriorly; epicnemial carina present ventrally, not extending dorsally onto lateral portion of mesopleuron. Pronotum smooth laterally, crenulate anteriorly. Ventral portion of mesopleuron separated by deep crenulate median groove, the groove widening posteriorly.

Legs: Fore tibia with a row of sparse thickened setae on anterodorsal surface. Hind femur 4.4–5.0 times longer than broad; inner hind tibial spur 0.2 times the length of hind basitarsus; hind basitarsus about 0.8 times the length of tarsomeres 2–5; tarsi clothed with short setae ventrally, setae long and sparse dorsally, longest dorsal setae longer than tarsus 2; tarsal claws simple.

Wings: Fore wing 2+3RS 0.8 times 4Rsa; 2CUa present; RS+M weakly sinuate; 1CU-a postfurcal to 1M, proximal segment of 1M as long as 1CU-a.

Metasoma ( Fig. 18 View FIGURES 17 – 20 ). T1 sparsely striated, with a pair of dorsal carina, which converges posteriorly but do not meet; T2 longitudinally striated with median carina present. Reminder metasoma smooth and polished, except for a transverse crenulated groove at base of T3. Petiole about as long as its apical width, apex 1.6–1.8 times wider than base, broadest subapically, narrowed at apex; base narrow, flared subbasally at dorsope. Ovipositor about as long as body, 2.9 times longer than hind tibia.

Color. Head and antenna dark brown; mandibles yellowish, except for darker teeth; maxillary and labial palpi whitish. Mesosoma yellowish, but metanotum, propodeum, and metapleuron brown. Legs yellowish, except mid and hind tibia and femur, and all last tarsomeres brown. Metasomal terga brown, first metasomal tergite darker; metasomal sternum light brown; ovipositor yellowish, apex blackish; sheaths light brown, but apical portion blackish. Wings infumate, stigma dark brown, veins brown, tegula yellow.

Remarks. Some color features could be altered over the years. The hind and mid tibia and femur was originally described as blackish, tough it was lighter when examined.

Variation. The striation of first and second metasomal terga varies in extension; longitudinal carina at second metasomal terga varies from complete to incomplete.

Male. Unknown

Biological notes. The specimens were reared from galls on leaf petioles on Anthurium sp..

Comments. This species resembles M. costalimai sp. nov., differing from it especially in the head shape, which is similar to M. rufithorax . It can be distinguished from all other Monitoriella species by the following combination of characters: concave area centrally on face, just bellow torulli (vs. somewhat raised in most species); mesothorax with a deep midventral groove throughout its length; frons granular-rugulose, without a carinated furrow; occipital carina incomplete mid-dorsally; pronotum laterally smooth; head 1.4 times wider than high, sub-triangular in frontal view; malar space large, about as long as eye height. It is the only known Monitoriella species reared from Anthurium sp.; all other species with known biology were reared from Philodendron spp. ( Fig. 8 View FIGURES 5 – 8 ).
