Coelinius wrayi Kula , new species

( Figs. 15–19 )

Diagnosis. Coelinius wrayi is most similar morphologically to Coelinius hopkinsii Ashmead and Coelinius muesebecki (Riegel) . The axillae extend posteriorly as thick, blunt protuberances in C. wrayi ( Fig. 18 ); they bear flangelike carinae in C. hopkinsii ( Fig. 20 ) and C. muesebecki .

Head: HL 0.87–0.88X HW, HW 0.98X TW, FW 1.63–1.65X FH, EL 0.74–0.81X EH, MNL 2.36–2.70X MNAW, MNAW 0.85–1.11X MNBW, F1L 1.11–1.40X F2L; antenna with 39–41 flagellomeres, maxillary palpus with 6 palpomeres, labial palpus with 4 palpomeres; face punctate, setose; frons mostly smooth, rugose ventromesally, glabrous; gena and vertex smooth with widely spaced punctures, setiferous; occiput smooth except punctate ventrolaterally, setiferous ventrolaterally but otherwise glabrous; eye virtually glabrous; clypeus protruding to degree that apical rim appears absent, punctate, setose; mandible ( Fig. 16 ) with four teeth, outer surface setiferous except teeth glabrous, punctate except teeth smooth and with ridges associated with tooth 1 and 3, tooth 1, 3, and 4 rounded apically, tooth 2 acute apically, tooth 1 and 3 forming less than 90° angle and similar in size and shape, tooth 2 elongate and triangular, tooth 4 between tooth 1 and tooth 2 as flangelike protrusion at base of tooth 2.

Mesosoma ( Fig. 17 ): ML 2.43–2.68X MW, ML 1.82–1.96X MH, MW 0.73–0.75X MH, SSL 0.20–0.30X SSW; pronotal collar smooth anteriorly and crenulate posteriorly, pronope present, lateral portion of pronotum crenulate-rugose ventrally, posteriorly, and in anterior furrow with remainder smooth or coriaceous with punctures, collar setiferous, lateral portion setiferous posterodorsally and along margins with remainder glabrous; notauli present, extending posteriorly on mesoscutum into deep furrow anteriad transscutal articulation, crenulate; mesoscutal midpit represented by rugose furrow spanning from middle of mesoscutum posteriorly to transscutal articulation; mesoscutum (excluding lateral margin, notauli, and midpit) with median lobe punctate and lateral lobes coriaceous mesally and punctate laterally, setose except lateral lobes glabrous mesally; scutellar sulcus bearing median longitudinal ridge along with crenulae and rugae; axillae extending posteriorly as thick, blunt protuberances ( Fig. 18 ); scutellar disc smooth with widely spaced punctures to punctate, setiferous; metanotum with flange mesally; propodeum areolate-rugose, setiferous; precoxal sulcus present along entire length of mesopleuron, rugose; posterior mesopleural furrow entirely crenulate; mesopleuron (excluding precoxal sulcus and posterior mesopleural furrow) coriaceous except subalar groove and anterior margin crenulate-rugose, setiferous anteriorly, ventral to precoxal sulcus, and diagonally from subalar area to posteroventral corner near mesocoxa; metapleuron areolate-rugose, setose.

Forewing ( Fig. 19 ): Hyaline; stigma with fairly discrete proximal and distal margins, semielliptical; vein r arising from middle of stigma; with following veins complete and tubular: C+SC+R, 1CUa, 1CUb, 1-1A, 2-1A, 1RS, 1M, (RS+M)a, 1m-cu, 1cu-a, 2CUa, 2cu-a, r, 2RS, and 3RS; M+CU nebulous proximally transitioning to tubular distally; 2M transitioning from tubular proximally to nebulous then spectral distally; vein 3RS evenly curved to wing margin; vein 1cu-a distad vein 1M; vein 1m-cu basad vein 2RS.

Hind wing ( Fig. 19 ): Hyaline; basal and subbasal cells enclosed by tubular veins; R and R1 complete and tubular; RS and 2M nebulous proximally transitioning to spectral distally; m-cu absent.

Metasoma: T1L 4.04–4.21X T1W; subcylindrical; t1 areolate-rugose, dorsal carinae not extending beyond dorsope; t2 coriaceous, t3 coriaceous or smooth, t4–t8 smooth; t2–t3 setiferous, setae in no apparent pattern, t4–t8 setiferous, setae located in posterior half of each tergum but otherwise in no apparent pattern.

Color: Head (excluding mouthparts and antenna) brown, mandible yellow except tooth 2 mostly brown and margins brownish, palpi brownish yellow, antenna with scape yellow and pedicel brownish yellow, flagellum brown; mesosoma brown except propleuron yellowish brown and pronotum yellow to brownish yellow anteriorly and brown posteriorly; pro- and mesothoracic legs yellow, metathoracic leg yellowish brown except trochanter, trochantellus, and tarsus yellow; metasoma brown with t1 darker than other terga.

Host. Unknown.

Material examined. Holotype male: Top label (white; typewritten)= U.S.A., “VIRGINIA:Giles Co. [;] Mountain Lake Biol. Station [;] 37°22'25.69"N, 80°31'25.41"W ”. Second label (white; typewritten)=“forest along Spring Road [;] 4.viii.-15.viii.2009 [;] R.R. Kula Malaise trap” (USNM). Paratype: 1 3 same data as holotype (USNM).

Etymology. The species is named in honor of Brendan Wray for his assistance to the author as an Intern at the Smithsonian Institution National Museum of Natural History.

Discussion. Coelinius wrayi fits Lepton Zetterstedt (= Coelinidea Viereck ) sensu Griffiths (1964). The monophyly of subgenera recognized previously within Coelinius sensu lato is questionable except for Polemochartus Schulz (Kula 2008) . Therefore, Coelinius wrayi is not formally assigned to a subgenus at this time.
