HOLOTYPE: Male: MALAYSIA: Sabah: Tenompok , 6.01777 ° N 116.48555 ° E, 637 m, 10–19 Feb 1959, T.C. Maa ( AMNH _ PBI 00041548 View Materials ) ( BPBM type# 16726) ( BPBM). GoogleMaps

DIAGNOSIS: Recognized by its single proepisternal lobe, orange-brown coloration, punctate pronotum and extremely long, thin left paramere. The genitalia of drepanopenis are very similar to those of prolixipenis , but the latter is much darker in coloration and lacks punctures on the pronotum.

DESCRIPTION: COLORATION (figs. 4, 6): Head: Mostly light orange-brown, frons with faint, darker brown vittae; raised tubercles adjacent to eyes yellow; ocular margins and posterior margin of vertex with yellow piping; clypeus, mandibular and maxillary plates, and gena light orange-brown; buccula yelloworange; labrum and labium orange-brown, darker brown apically. Antenna: AI pale orange-brown, with thin dark brown annulations at base and apex; AII light orange-brown with dark brown apical annulation; AIII and AIV dark brown, yellow basally. Thorax: Pronotal collar yellow, anterior margin dark brown; pronotum mostly orange-brown with faint yellow median stripe; margins with thin yellow piping; proepisternum yellow, remaining thoracic pleura orange-brown, posterior margins becoming yellow; mesoscutum orange-brown; scutellum orange-brown with faint dark brown markings on lateral margins and yellow markings laterally and apically. Hemelytra: Orange-brown, slightly lighter anteriorly and at cuneal fracture; clavus slightly darker than remainder of hemelytron; cuneus slightly yellow basally, becoming orange along outer and apical margins; membrane pale brown with darker brown veins. Abdomen: Uniformly yellow-orange; parameres glossy amber. Legs: Yellow-orange, metafemur faintly orange at apex, laterally with diagonal brown stripes. SURFACE AND VESTITURE (figs. 4, 6): Head smooth and glossy with widely spaced punctation medially on vertex, sparsely covered with short, white setae; pronotum with shallow, even punctation; scutellum slightly rugulose and impunctate; propleuron, metepimeron, and hemelytra impunctate; head and dorsum with sparse distribution of short, white, decumbent setae. STRUCTURE (figs. 4, 6): Head: Broad; frons weakly convex; vertex with minor swellings medially and adjacent to eyes; posterior margin of head carinate and weakly medially rounded. Thorax: Pronotum broad and convex, margins thinly carinate, anterolateral margins slightly upturned, submarginal region of humeral angles depressed, posterior margin thin, callar region undifferentiated; proepisternum unilobed; posterior margin of metepimeron truncate; metanotum not prominent and flared; scutellum swollen. Hemelytra: Costal margin thin, somewhat flared over its entire length and weakly sinuate. Legs: Metatibial spines short and thin. Abdomen: When viewed laterally, posterior margin of abdominal sternite II not angular. MALE GENITALIA (fig. 10I–K): Right paramere small and triangular (fig. 10J); left paramere extremely long, thin, curved, slightly twisted along its axis (fig. 10I), and extending beyond the margin of the pygophore (fig. 10K); posterior margin of pygophore biconvex, with fold on left forming a shallow groove (fig. 10K). FEMALE PARAGENITALIA: Unknown.

ETYMOLOGY: This species name, drepanopenis , is derived from Greek drepanon (‘‘scimitar, sword’’) and Latin penis (lit., ‘‘tail’’) and reflects its extremely long, swordlike left paramere.

HOST: No host information.

DISTRIBUTION: Known only from Sabah (map 5).
