(Figs 2, 6, 9, 14, 19, 23, 24)
Description. Holotype Ƥ. Body length: Ƥ 4.0– 4.2 mm.
Head (Figs 6, 14, 23). Transverse, in dorsal view 2.24–2.40 times wider than long; 1.2 times wider than mesoscutum. Eyes very large, in lateral view twice as long as temple. Head 1.8 times wider than high in frontal view; malar space 1/3 times the eye height. Face rugulose, dorsomedial polished area absent, 1.85–2.10 times wider than high, 0.51 as wide as head. Temple and gena granular, malar space smooth. Clypeus dorsally protruding. Mandible thick; ventral teeth longer than dorsal. Vertex granular; ocellar triangle elevated; frons with deep carinated depression. Ocelli large, maximum diameter of posterior ocellus ~1.6–1.7 times larger than distance between posterior ocelli; shortest distance between eye and ocellus 2.30–2.57 times the maximum diameter of posterior ocellus. Occipital carina completely absent (Fig. 23), except for a very short ventral ridge connected to the hypostomal carina. Antenna slightly longer than body; flagellomere setae shorter than its width; flagellum 28 jointed. Labial palpi 4 segmented, maxillary palpi broken.
Mesosoma (Figs 9, 14). 1.5 times longer than high, almost as high as wide. Anterior declivity of mesonotum vertical, median mesonotal lobe weakly indented, lateral lobes bare medially. Notauli deep and crenulate, converging in a rugose area posteriorly, this area restrict to posterior third of mesoscutum. Prescutelar sulcus divided by median carina, with some additional weak lateral carina. Metanotum smooth. Propodeum with very short median carina anteriorly which forks near metanotum enclosing a rugulose areola that extends to posterior margin of propodeum; posterolaterally without short tubercles; lateral carina between propodeum and metapleuron absent. Metapleuron rugose. Sternaulus present anteriorly, shallow and wide; rugose anteriorly; ventral margin weakly granulate. Epicnemial carina weak but present ventrally, absent laterally. Pronotum smooth laterally, weakly crenulate anteriorly, dorsally granular. Ventral portion of mesopleuron not separated by median groove.
Legs (Fig. 24): Fore tibia with a row of spines anterodorsally; tibial spur long and curved, half as long as basitarsus. Hind femur 3.6 times longer than broad; inner hind tibial spur longer than outer, 0.25 times the length of hind basitarsus; hind basitarsus 0.66 times the length of tarsomeres 2–5; tarsi densely clothed with short setae ventrally, setae long and sparse dorsally; tarsal claws simple.
Wings: Fore wing 2nd submarginal cell pentagonal, 2RS 1.15 times longer than 3RSa; 2Cua short but present; RS+M sinuate; 1CU-a just postfurcal to 1M.
Metasoma (Fig. 19). T1 rugose, without median longitudinal carina, pair of lateral carina present on anterior half; T2 longitudinally striate, median carina absent; T3, T4 and T5 finely punctate; reminder terga polished. Petiole short, 0.7 times longer than apical width, apex 1.5 times wider than base, broadest subapically, narrowed at apex. Base narrow and flared sub-basally at dorsope. Ovipositor length 2.7 times longer than hind tibia, 2.3 times longer than mesosoma; apex serrate ventrally.
Color. Brown, becoming lighter from head, which is dark brown, toward metasomal apex; metasoma except T1 and T2 light brown to yellowish. Legs yellow. Mandibles, maxillary palpi, and propleuron yellowish brown. Ovipositor sheaths with a white band medially, brown at base and blackish apically. Antenna black; scape, pedicel and first flagellomere yellow. Wings weakly infumate; veins brown, but 2M, r-m and 3RSb of fore wing lighter.
Variation. The paratype differs in antenna color, 2nd and 3rd flagellomeres with yellow basal half; antenna with 29 flagellomeres; ocelli larger, maximum diameter of posterior ocellus twice the distance between posterior ocelli, distance between eye and posterior ocelli 2.7 times maximum diameter of posterior ocellus; the face is entirely granular–rugulose; sternaulus on metapleuron more extensively rugose.
Male. Unknown
Comments. The absence of occipital carina, and presence of a row of spines on the fore tibia are exclusive features within Monitoriella spp. It resembles M. rufithorax by the midventral line of mesothorax that is not set within a deep groove, and the face without a raised area bellow toruli. The large eyes of this species are similar to those of M. curta, though M. spinata possesses a shorter malar space (about 1/3 of eye height in frontal view). The extensive dark coloration of this species, including thorax, with yellow legs, resembles M. elongata; differing from the latter by the antenna, with at least scape, pedicel and first flagellomere yellow.
Etymology. The species name refers to the row of spines present on the anterodorsal surface of the fore tibia.
