Furcadia Opitz , new genus
Type Species. Furcadia sandala Opitz , new species.
Diagnosis. In a key to the genera of Orthopleurinae ( Opitz 2009a) , Furcadia keys to the Old World genus Funicula , from which Furcadia is distinguished by a more robustly developed antennal capitulum (compare Figs. 3 and 8 View Figs ), subsecuriform maxillary and labial terminal palpomeres, and a well-diffentiated pronotal arch (compare Figs. 21 and 23 View Figs ). Also, the spicular apodemes are not contiguous in Furcadia ( Fig. 13 View Figs ), whereas in Funicula these apodemes are contiguous for nearly their entire length ( Fig. 12 View Figs ).
Synapotypic Characteristic. Intraphallic-plate membrane spinose.
Description. Size: Length 4.8–8.0 mm; width 1.2–2.0 mm. Form: Oblong-rectangulate, about 3.5 times longer than broad. Vestiture: Discs of cranium and pronotum vested with pale setae, elytral disc vested with 1° setae and shorter, profusely distributed 2° setae. Head: Cranium quadrate, frons wide, indented with small, contiguous, setiferous punctation; gula small, triangular, sutures oblique, gular process narrow and bifid; labrum short, medial incision deep; mandible short, subacuminate; maxillary and labial terminal palpomeres subsecuriform; eyes small, finely faceted, ocular notch large; antenna ( Figs. 3, 5 View Figs ) capitate, capitulum lax, scape elongate, longer than combined length of pedicel and antennomere 3, funicular antennomeres progressively shorter to capitulum, capitular antennomeres 9 and 10 sexually dimorphic, triangular in females, oblong-triangular in males, antennomere 11 oblong. Thorax: Pronotum ( Fig. 23 View Figs ) quadrate, with tumescences on pronotal disc, lateral margins slightly incised at anterior third, arch welldeveloped, remainder of pronotum finely punctate, transverse subapical and prebasal depressions welldeveloped, prointercoxal process expanded distally; pronotal projections long, contacting but not fused with prointercoxal process; elytron sculptured with asetiferous punctation that diminish after basal half, punctuation subseriate in basal half, 1° setae always adjacent to asetiferous punctation, 2° setae present, epipleural fold narrowing to elytral apex, anterior margin carinate; tibial spur formula 2-2-2, tarsal pulvillar formula 3-3-3, unguis with well-developed

denticle. Abdomen: Six visible sternites; aedeagus ( Figs. 14, 15 View Figs ) with lateral lobes feebly developed; phallobasic struts not confluent with phallobasic apodeme, phallobasic rod broad; phallic plates narrow; spicular plates flared ( Fig. 13 View Figs ), plates slightly truncate, spicular apodemes not fused, intraspicular plate oblong-linear.
Distribution. This monotypic genus is known from Laos.
Etymology. The genus name Furcadia is a compound name that stems from the Latin furca (= fork) and the Greek dia (= between). I refer to the complete separation of the spicular apodemes. Gender: Feminine.

Type Material. Holotype: ♀. Phou Pan (Mt.), Houa Pan Prov., NE LAOS, 10–22.V.2011, St Jakl leg ( FSCA) . Paratypes: Two specimens. LAOS, Phongsaly Province, 21°41 ′ N 102°6E ′, Phongsaly environs, 6–17-V-2004, 1500 m, M. Brancucci ( RGCM, 1; WOPC. 1) GoogleMaps .
Diagnosis. This is the only species in the genus, so it is recognized by the combination of characteristics defining the genus.
Description. Size: Length 4.8 mm; width 1.2 mm. Form: As in Fig. 31 View Figs . Color: Black, except frons, mouthparts, prosternum, pterothoracic venter, and abdomen dark castaneous; pronotal arch black, pronotal disc red. Head: Antennal capitulum welldeveloped ( Figs. 3, 5 View Figs ), capitular antennomeres 9 and 10 triangular, antennomere 11 oblong-rectangular, funicular antennomeres subfiliform; maxillary and labial terminal palpomeres digitiform; eyes much narrower than frons (EW/FW = 15/30). Thorax: Pronotum ( Fig. 23 View Figs ) quadrate (PW/PL = 70/70), lateral margins incised at apical 1/3; elytral asetiferous punctation small and shallow, extending to just beyond elytral middle, interstitial spaces arenose, epipleural fold narrowing to elytral apex. Abdomen: Pygidium scutiform; aedeagus ( Figs. 14, 15 View Figs ) with lateral lobes feebly developed; phallobasic struts not confluent with phallobasic apodeme, phallobasic rod broad; phallic plates narrow; spicular plates flared ( Fig. 13 View Figs ), plates slightly truncate, spicular apodemes not fused, intraspicular plate oblonglinear.
Natural History. The type specimens were collected during May, two at 1,500 m.
Variation. Size: Length 4.8–8.0 mm; width 1.2–2.0 mm. Except for body size, the type specimens are quite homogeneous.
Distribution. This species is known only from Laos ( Fig. 39 View Figs ).
Etymology. The Latin specific epithet sandala (= slipper or sandal) refers to the body form of this beetle.
