Allorhogas inquilinus sp. nov.
Diagnosis.
This is a morphologically distinctive species, which could be distinguished from the remaining described members of Allorhogas from Brazil by having: 1) eyes small, malar space 0.8 times eye height (eyes larger, malar space less than 0.8 times eye height in the remaining species); 2) frons and vertex strongly rugose-coriaceous (generally coriaceous in the remaining species; striate-rugose and coriaceous in A. copaiba ); 3) face coriaceous with longitudinal v-shape striation (variable but never with this sculpture in the remaining species); 4) propodeum entirely strongly rugose-areolate, with two indistinct diverging carinae (at least partially coriaceous and with distinct diverging carinae in the remaining species); 5) hindwing with vein m-cu almost straight, slightly curved towards wing base (slightly curved towards apex in the remaining species); 6) apical half of third and remaining metasomal tergites punctate-slightly costate (usually smooth in the remaining species).
Description.
Female. Body size 3.3 mm (Fig. 4A View Figure 4 ), forewing 2.3 mm. Colour: body entirely honey yellow; scape, pedicel and first four flagellomeres honey yellow, remaining flagellomeres dark brown; eyes silverish black; palpi yellow; legs honey yellow, tarsi brown; tarsal claws black; wings hyaline; forewing veins brown, stigma brown; hindwing veins honey yellow; ovipositor sheaths black, ovipositor honey yellow, apex strongly sclerotised.
Head: transverse in dorsal view, 2.4 times wider than its median length (dorsal view) (Fig. 4B, D View Figure 4 ), and 0.6 times as long as high (lateral view); occipital carina complete and reaching hypostomal carina before mandible; post ocellar line (POL) as long than ocellar diameter (OD), 0.3 times ocular ocellar line (OOL); frons and vertex strongly rugose-coriaceous, temple and gena coriaceous-slightly rugulose; face pilose, costate-rugose in longitudinal v-shape and coriaceous (Fig. 2D View Figure 2 ); area surrounding clypeus and gena with large, dense pilosity; clypeus transversally costate-rugose; frons excavation distinct but not defined by sharp lateral margins; eye 1.1 times longer than wide; eye width 1.9 times longer than temple in dorsal view; malar space 0.8 times eye height and 2.0 times longer than width of hypoclypeal depression; mandibles bidentate; antenna with 29 flagellomeres, first flagellomere about 3.0 times longer than wide, 1.3 times longer than second flagellomere.
Mesosoma: 1.6 times longer than high (Fig. 4B View Figure 4 ) and 1.4 times longer than wide (Fig. 4C View Figure 4 ); pronotal collar short but visible in dorsal view, pronotal furrow wide, scrobiculate; mesoscutum transverse in dorsal view, its median length 0.8 times its width; mesoscutal lobes rugose-coriaceous, with large, dense pilosity; median mesoscutal lobe with a wide furrow that turns more distinct basally; notauli wide, deep and rugose-scrobiculate, not meeting, reaching the end of scutellum in a rugose area; scutellar disc coriaceous, prescutellar furrow with five transverse carinae; mesopleuron transversally rugose-coriaceous anteriorly, coriaceous medially and basally; subalar groove wide and rugose-scrobiculate; precoxal sulcus wide, scrobiculate-coriaceous, running along 0.6 of mesopleuron; metapleuron entirely rugose-areolate; propodeum entirely strongly rugose-areolate and slightly coriaceous basally, with two indistinct diverging carinae.
Wings: forewing 3.2 times longer than wide (Fig. 4F View Figure 4 ). Pterostigma 4.0 times as long as wide and 0.7 times as long as R. Vein r as long as 3RSa, 0.3 times as long as 3RSb, and as long as r-m. Vein 2RS interstitial with m-cu, vein RS+Mb absent. Hindwing vein M + CU as long as 1 M, vein m-cu almost straight, slightly curved towards wing base.
Legs: hind coxa with distinct, pointed basoventral tooth, with large, dense pilosity, ventrally rugose. Hind femur 3.3 times longer than wide.
Metasoma: first tergite 1.7 times wider than long, costate, slightly punctate laterally, with two longitudinal carinae only distinct at base; transverse basal carina distinct (Fig. 4E View Figure 4 ). Second and basal half of third tergite costate-slightly punctate, line between second and third tergites distinct and straight; apical half of third and remaining tergites punctate-slightly costate. Ovipositor sheaths 0.6 times as long as metasoma.
Variation.
Body size 3.0-4.0 mm. Antenna with 28-31 flagellomeres.
Male. Similar to female. Body size 4.0 mm. Antenna with 30 flagellomeres. Hind femur swollen, about 3.0 times longer than wide.
Holotype.
Female (DCBU 420452). Brasil, RD, Santo Antonio da Patrulha, Coxilha das Lombas; from galls of Cecidonius pampeanus ( Lepidoptera , Cecidosidae ), 18.IV.2015; G. R.P. Moreira & S. L. Bordignon col.
Paratypes.
(DCBU420453-58, 420472; IBUNAM). 1 male, 4 females, 1 specimen without metasoma (DCBU 420457). Same data as holotype.
Biology.
A detailed description of the feeding biology of A. inquilinus was previously reported by Moreira et al. (2017). This species was confirmed by the authors as a gregarious inquiline of stem galls made by the cecidosid moth Cecidonius pampeanus Moreira & Gonçalves on Schinus weinmannifolius Mart. ex Engl. ( Anacardiaceae ).
Etymology.
The epithet of this species is a reference to its inquiline biology.
