==Type material==
'''Holotype''' male, THAILAND, Chiang Dao, 1000m, [http://ptp.pensoft.eu/redirect_to_googlemap.php?labels%5B0%5D=19%C2%B025%27N%2C+98%C2%B052%27E&coordinates%5B0%5D=19%C2%B025%27N%2C+98%C2%B052%27E 19°25'N, 98°52'E], 17–24.v.1991, leg. V. Kubáň (ICCM). Paratypes, two males and one female, same data as holotype (ICCM).

==Distribution==
Thailand (Chiang Dao).

==Diagnosis==
''{{Taxon name|Prothemus lycoceroides}}'' sp. n. is fairly similar to ''{{Taxon name|Prothemus laticornis}}'' sp. n., but distinguishable by the narrower antennae, less prominent longitudinal elytral costae and less curved apices of parameres of the aedeagus.

==Description==
'''Male''' (Fig. 2<ref name="B1">{{aut|Kazantsev S}}, {{aut|Brancucci M}} (2007) Cantharidae. In: Löbl I Smetana A (Eds). Catalogue of Palaearctic Coleoptera, Vol. 4. Apollo Books, Stenstrup: 234-298.</ref >). Black. Pronotum and elytra red; pronotum with a darkened median stripe.<br />
Head surface dorsally densely and finely punctate, slightly depressed between eyes; ultimate maxillary palpomere elongate, securiform, widest near base, acute at apex; antenna extending to apical one-fourth of elytron, antennomere II as long as wide at apex, III–VIII flattened and serrate, at least 2.0 times as long as wide at apices, IX–XI slightly flattened and subparallel-sided (Fig. 10<ref name="B3">{{aut|Okushima Y}}, {{aut|Satô M}} (1997) Cantharid beetles of the genus ''Prothemus'' (Coleoptera, Cantharidae) of the Ryukyu Islands, southwest Japan. Elytra 25: 333-342.</ref >).<br />
Pronotum slightly wider than long, widest near base, all margins and angles rounded, disc distinctly convex, with an obscure median groove.<br />
Elytra long, about 4.75 times longer than pronotum and 3.2 times longer than wide at humeri, humeral width distinctly wider than that of posterior margin of pronotum, almost parallel-sided, disc surface densely and finely punctate, with 2 distinct longitudinal costae.<br />
Aedeagus (Fig. 12<ref name="B3">{{aut|Okushima Y}}, {{aut|Satô M}} (1997) Cantharid beetles of the genus ''Prothemus'' (Coleoptera, Cantharidae) of the Ryukyu Islands, southwest Japan. Elytra 25: 333-342.</ref >): fairly similar to ''{{Taxon name|Prothemus laticornis}}'' sp. n., distinguishable by less curved apices of parameres.<br />
'''Female'''. Similar to male, but larger and wider, eye smaller, antenna (Fig. 11<ref name="B3">{{aut|Okushima Y}}, {{aut|Satô M}} (1997) Cantharid beetles of the genus ''Prothemus'' (Coleoptera, Cantharidae) of the Ryukyu Islands, southwest Japan. Elytra 25: 333-342.</ref >) shorter and wider in middle antennomeres.<br />
Body length 13.2–13.8 mm, width 3.0–3.3 mm.

==Etymology==
The name of the new species is modified from ''{{Taxon name|Lycocerus}}'', alluding to its similarity to the members of some ''{{Taxon name|Lycocerus}}'' species.
