Iphiclus suturalis (Lacordaire, 1842)

Skelley, Paul E., 2009, Pleasing fungus beetles of the West Indies (Coleoptera: Erotylidae: Erotylinae), Insecta Mundi 2009 (82), pp. 1-94 : 33

Distribution. Iphiclus suturalis is the only known member of Erotylinae on Dominica ( Fig. 1b ).

Type Material. For Brachysphaenus suturalis, Lacordaire (1842) stated “De la Guadeloupe ” and preserved the species name “ suturalis ” proposed in the Dejean catalog (1836) under Aegithus . This again showed Lacordaire studied specimens from Dejean’s collection. A single specimen was located in Dejean material over a label “S. G. Oogaster, Brachysphaenus suturalis Guadeloupe, Dej., Lacord.” This specimen matched Lacordaire’s description and is considered type material. Lacordaire made no indication how many specimens were studied. To resolve nomenclatural confusion and fix the name to a single specimen, the male specimen of B. suturalis in the Dejean material ( Fig. 145 ) is here designated as the lectotype. The label data is as follows: “/ [green paper] D. Latreille / [red paper] LECTOTYPE Brachysphaenus suturalis Lacordaire , des. P. E. Skelley 2008 /” (MRSN).

Lacordaire’s type locality “ Guadeloupe ” is in error. All specimens studied that are conspecific with the lectotype are from Dominica.

Specimens Examined. In addition to the lectotype, 65 specimens were studied from Dominica: Portsmouth, Coconut Beach Motel, 6-29-2004, C.W. O’Brien (1- FSCA) ; Pont Cassé , 1380', 6-19-2004, C.W. & L.B. O’Brien (2- PESC) ; Pont Cassé , 1380', 6-24-2004, C.W. & L.B. O’Brien (6- PESC) ; Roseau R. Valley, 22-JUN-2004, C.W. & L.B. O’Brien (1- PESC) ; 2.5 to 3.5 km W. Freshwater Lake, Morn Tres Piston [Morne Trois Pitons] N.P., 23-JUN-2004, C.W. & L. O’Brien (1- PESC) ; town above Canefield , 19-JUN- 2004, C.W. O’Brien, on soft white fungus (7- PESC) ; 6 mi. E. Dublanc , 1250 ft., 16-AUG-1986, C.W.& L.B. O’Brien (4- PESC) ; Clark Hall , 9-FEB-1966, D. E. Johnson, polypore on log (1- WIBF) ; Clark Hall , 5-FEB- 1966, D.E. Johnson (4- WIBF) ; Trafalgar Village , 850 ft., 29-DEC-1978, M.A.& L.L. Ivie (5- WIBF) ; Layou , 1-7-[18]88, G.A. Ramage, fungi on fallen trees (5- NHML, PESC) ; Salibia , 30-JAN-1968, B. Malkin (2- FMNH) ; Bataka , 30-JAN-1968, B. Malkin (2- FMNH) ; Roseau Botanical Garden , 2-FEB-1968, B. Malkin, FM(ND) # 68-3, on fungus (preserved) (3- FMNH) ; Trafalgar Village , 850 ft., 29-DEC-1978, M.A. & L.L. Ivie (6- BMUC, PESC) ; Loyou , 30-3-[18]88, G.A. Ramage, 97-67 (3- NHML) ; Layou, G.A. Ramage, 97-67 (8- NHML) ; St. David , 3 mi. W. of Pontcasse [sic], 7-10-JUL-1970, J. H. Frank, under bark of fallen hardwood tree (2- NHML) ; Corlet [?], OCT-1901, in decaying timber, (2- NHML) .

Remarks. See remarks under I. guadeloupensis for nomenclatural concerns. Leng and Mutchler (1914) first recorded this species from Dominica as Brachysphaenus marginatus , which was based on the previous synonymy of the names. This record is repeated in subsequent faunal lists ( Blackwelder 1945, Peck 2006).
